Energy-saving paint - selection criteria. Liquid energy saving materials Where to use energy saving paint

In the 1970s, American scientists were tasked with developing a special material for spacecraft that could withstand both extremely high and very low temperatures. The created composite material, consisting of a polymer matrix and a special filler, was called energy-saving paint. The topical issue of energy saving in the literal sense today made energy-saving paints fall from the sky to the ground. Today, this modern material is effectively used for "domestic" purposes as a thermal insulation coating for building envelopes and pipelines.

Operating principle

The hollow microspheres that make up the filler look like powder. The smallest particles have a diameter of 10 to 200 microns and a wall thickness of 0.5-2 microns. The general properties of the product depend on their size, quantity and the material from which they are made.

The secret of the energy-saving properties of the coating is as follows. After drying, the composition turns into a dense and elastic membrane. The microspheres in the membrane are able to reflect and scatter about 90% of infrared radiation and more than 80% of visible sunlight. Energy-saving paint is a kind of "climate control" that does not let heat into the house in summer, and keeps heat inside in winter and is a barrier to the street cold. In numerical terms, the reduction of heat loss from building envelopes when using energy-saving coatings can reach 40-45%.

Application area

• external and internal surfaces of enclosing structures of residential buildings;
• roofs of buildings;
• slopes, cornices, balconies, loggias;
• rooms with high humidity and poorly heated rooms (bathrooms, toilets, showers, changing rooms, etc.);
• external and internal surfaces of the enclosing structures of buildings and structures for industrial purposes (workshops, warehouses);
• external and internal surfaces of the enclosing structures of public buildings (railway stations, sports halls, shopping and entertainment centers, etc.);
• enclosing structures of premises with special temperature conditions and humidity (freezers, swimming pools, etc.);
• roofs of hangars, garages, containers, trailers, refrigerators;
• air conditioning systems;
• pipelines;
• tanks for storage of oil, oil products, gas, water;
• bridges.

Energy-saving coating reduces heat loss, protects structures from corrosion and overheating, prevents the formation of condensate, reduces operating costs and less frequently repairs. In addition, energy-saving paints, along with high functionality, look quite aesthetically pleasing and are great for finishing buildings.

On average, energy-saving paints from various manufacturers withstand temperature ranges from -60°C to +200°C. Although the upper limit for some modern modifications can reach +500°C.

Due to the peculiarities of the composition, energy-saving adhesives have good adhesion to almost any surface, whether it is a concrete or brick wall, a metal pipe, a wooden or plasterboard partition. In this case, the surface can be absolutely any shape - the paint will lie flat.

How to work with energy saving paints

The base for the coating must be dry and clean, the preparation is carried out in accordance with GOST 28196-89 (clause 6.3.) As when working with water-dispersion paints. For better adhesion on the surface, it is recommended to apply a primer that does not contain organic solvents.

To apply paint to the surface, use a brush, roller or spray gun. One layer is applied first. The time required for drying is 24 hours, then polymerization occurs within 12 hours (the same membrane is formed). After that, you need to apply a second layer. Paint consumption depends on the base material and can range from 0.155 to 0.5 liters. per sq.m. (one layer). The thickness of the coating is approximately 0.25-0.5 mm, due to which the paint does not weigh down the structures and does not occupy a usable area, in contrast to the use of multilayer insulation.

Energy-saving paints must be mixed well in a bucket or some other container before application. You can use an electric drill with a special nozzle for this. It is not necessary to dilute the paint with water - it is sold ready-made.

If the structures are in an open area, it is not recommended to work when it is raining, it is also necessary to provide protection from possible precipitation for the first four hours after application. The temperature during work should not be below 5 °C.

Caring for painted surfaces is very simple - they can be washed with any detergent. If it becomes necessary to replace the coating, this can be done using a grinding tool. But it should be noted that the paint has a rather long service life. Manufacturers usually give a guarantee of at least 10 years. But, as experience shows, on the outer surfaces of house structures, it should work confidently up to 50 years in normal Russian climatic conditions and up to 15 years if it is subjected to harsh environmental influences.

New trends and developments

Today, paints from various manufacturers can contain microspheres made of glass, ceramics, and be produced in the form of aerogels with the smallest particles developed using the latest nanotechnologies, in the form of insulating putties.

Recently, a fundamental novelty has appeared on the market - a ceramic additive that can be mixed with ordinary paint, turning it into an energy-saving one. An environmentally friendly and non-toxic dry powder, consisting of ceramic granules, is added to the paint at the rate of 110 g of additive per 1 kg of paint. The additive can also be used with other coatings and composite materials for interior and exterior decoration.

But this invention is not the limit. Science has gone further, and today, on the basis of an energy-saving additive, energy-saving wallpapers are produced that are glued under ordinary ones. In addition to performing thermal insulation functions, they also smooth out irregularities on the wall well.

Effect in numbers

Reducing heat loss from building envelopes when using energy-saving coatings is 40-45%.

Comparison of the properties of one of the modifications of energy-saving paint with other heat-insulating materials.

Energy saving paint . This material is characterized by flexibility, lightness, extensibility, good adaptation to surfaces. Energy saving paint consists of microscopic ceramic or silicone balls, which, being hollow inside, are suspended in a liquid consisting of synthetic rubber and inorganic pigments. This paint is unique because of its thermal insulation properties, which are the result of the intense interaction of the air molecules inside the bubbles.

In addition to the fact that the paint has thermal insulation properties, it does not support combustion at all. When painted surfaces start to burn, carbon and nitrous oxide are released from the paint film, which slows down the spread of fire.
However, energy-saving paint is used not only as a material for insulation, it has the ability to reflect the sun's rays. Due to this property, the paint during the summer heat reduces heat penetration into the room by several times, and this leads to a decrease in the air conditioning of the rooms and an increase in their comfort level.
Energy saving paint can be applied to any surface - brick, concrete, metal, glass, plastic, rubber and even cardboard, in a word, any surface can be painted with this paint (walls and ceilings, facades and roofs, slopes and floors, etc.).
Corundum, Izollat ​​and Keramoizol paints have gained particular popularity among energy-saving paints.

Corundum

Very thin thermal insulator in the form of a suspension. Corundum is a highly porous energy-saving material, the principle of which is based on the mechanism of thermal blocking of heat transfer by radiation, convection and conduction, due to which it is able to reflect and scatter more than 80% of radiation. Low thermal conductivity weakens the heat flow coming from the outside, and insignificant properties for radiation reduce the level of the outgoing heat flow, as a result of which heat losses are significantly reduced. The coating "Korund" has high thermal and operational characteristics, it has a very high economic efficiency. The period of successful operation of surfaces coated with "Korund" is at least 15 years. Among all domestic energy-saving materials, Korund is one of the cheapest and highest quality.
"Korund" is used for thermal insulation of pipelines for supplying hot and cold water (on pipes for cold water, the coating is used to prevent condensation), for facades and roofs, interior walls, concrete floors, air conditioning ducts.

Isollat

This is an innovative liquid ceramic universal energy-saving material developed on the basis of nano-technologies. The liquid polymer composition is saturated with ceramic microscopic hollow spheres, inside which rarefied air is contained. Thanks to these microspheres, the Isollat ​​coating can refract, dissipate and reflect radiant heat.
energy saving materials
This coating has a low coefficient of thermal conductivity, it has good resistance to precipitation and anti-corrosion properties. "Isollat" refers to "breathable" materials, it is steam and waterproof. The period during which the paint retains all its properties is at least 15 years. I also call Isollat ​​paint-thermos and are used for painting indoor walls, as well as facades and roofs of buildings, external pipelines.

Energy saving materials

« Keramoizol"- a liquid composition containing a huge number of microscopic hollow glass spheres, the principle of operation of which is a bit similar to the principle of a reflector device, but reflecting infrared rays.
This coating has a number of advantages, including low vapor permeability, high heat-saving capacity, ease of application and ease of repair of a damaged layer.

« Keramoizol”, made on a varnish basis, allows you to carry out insulation work at sub-zero temperatures. The service life of this coating is at least 7 years.

« Keramoizol"also called a "warm mirror" and is used for thermal insulation work for structures of any complexity and shape (foundations, internal and external walls), applied to various joints, pipes, interpanel seams.

How to make your home and garden beautiful. Artificial stone is identical in appearance to natural stone, and many different textures, amazing colors and original shades make it many times superior to natural stone. The price of artificial stone, however, is more attractive, and the process of purchase and delivery is much more economical and faster.

Energy saving in construction is one of the most important tasks. Resources are constantly becoming more expensive. If you do not take effective measures to insulate buildings and structures, then high financial costs are guaranteed. The latest heat-insulating material is energy-saving paint. It first appeared in the space industry, where it was supposed to protect ships from the icy cold of space and the heat when passing through the atmosphere.

Its composition is quite simple: hollow microspheres with a diameter of 10 to 200 microns and a wall thickness of about 1 micron are added to the polymer base. The composition is applied to the surface with a brush or spray. Drying, it forms an elastic and elastic coating, tightly adhered to the base. It has unique mirror properties. More than 80% of sunlight and almost 90% of infrared radiation are reflected from it. This means that the coating does not allow heat to escape in winter and does not let heat in in summer.

Energy-saving paints of the latest generation have extremely useful properties:

• resistance to any precipitation, wind load and ultraviolet rays;
• high decorative and aesthetic characteristics due to the original surface texture and a wide range of colors;
• more than a ten-year service life of the coating;
• compatibility with any building materials: bricks, blocks, concrete, wood, drywall, metal, etc.;
• anti-static, safety and environmental friendliness;
• lack of labor-intensive work and special devices for thermal insulation.

The use of energy-saving paint in the construction of residential and industrial buildings is not limited to reducing heat losses. At the same time, reliable protection against corrosion, prevention of heating and formation of condensate is achieved. In addition, paint is also a means of finishing. All this allows to reduce operating costs and increase the overhaul interval.

The use of energy-saving paints is effective not only in construction. The scope of their application is constantly expanding. Today they are successfully used for protection and thermal insulation of many objects:

• metal hangars, bridges, railway tanks, refrigerator cars, garages, sheds, containers and many other metal products;
• rooms with high humidity, such as showers, bathrooms or toilets;
• swimming pools, freezers, saunas and other facilities that impose special conditions on temperature and humidity;
• storage tanks and pipes for transportation of water, steam, gas, oil and oil products.

Today, construction stores offer their customers various materials that have both necessary functions and useful ones. Among these products, a new paint and varnish material is presented on the construction market - energy-saving paint.

The main function of such paint is to keep the heat of the surface on which it is applied as much as possible. This paint is a product of a new generation. The history of the appearance of such paints is mentioned back in the 70s, when it became necessary to isolate the outer surface of spacecraft. Then the well-known NASA company developed such material. Subsequently, unique paint began to be used for various fields of activity. In particular, it almost completely replaced the need to insulate pipes.

What does it consist of

Energy-saving paint includes two components:

1. Powdered balls (spheres).
2. Resin.

One such ball has a diameter of 10 to 200 microns. By the way, the percentage of the microsphere in the paint depends on this indicator, which directly affects its characteristics.

Not so long ago, no one knew about such paint, because it was used exclusively to cover American military equipment. And only recently in Russia they also began to produce a similar paint for use in housing and communal areas.

Despite the fact that the Russian market has a wide selection of various heat-saving materials, in particular, insulation, paint is the only unique material that does not let the cold outside the building. It works on the principle of accumulating heat that leaves the room, then to give it back.

Important: heat-saving paint "works" well in a duet with a warm floor, which has an infrared film structure. Thus, when a warm floor is laid in the room, the heat will not penetrate into the lower rooms, but will return back through accumulation. If you follow this technology, you can increase the thermal coefficient of the room by about 40 percent.

How to apply

As strange as it may sound, the paint is applied to the surface in the same way as ordinary paint using a roller, brush or a special device with a sprayer. The energy-saving effect paint has excellent adhesion properties. It easily covers any surface:

• wood;
• metal;
• concrete surface;
• brick;
• rubber;
• from cardboard;
• from glass.

In order to get the maximum expected effect from the paint, it is applied in several layers. The paint application technology provides for a coating in three layers. If the consumer wants to save money, and it is worth noting that the price of the paint is quite high, then he will not get the desired effect of keeping the heat in the room. By the way, this indicator is easily checked: if the paint is applied not in three, but in one or two layers, then the surface does not have an even color, which means that it makes no sense to talk about the direct purpose of the paint.

Before applying energy-saving paint, the surface must be carefully prepared: remove debris, dirt, rust and degrease. The surface temperature must be at least seven degrees and not higher than one hundred and fifty degrees Celsius. Paint can be applied in any way. After applying the first layer, after ten minutes a thin film is formed on the surface, which dries up during the day. And only after the first layer has completely dried, the next layer is applied.

Paint consumption when working with a roller is half a liter per square meter, with a spray gun - one hundred grams less. One liter of paint allows you to cover about 2.5 square meters of area.

Paint in action

Energy-saving effect paint is not destroyed by high temperature. It is able to withstand maximum temperatures up to 250-260 degrees Celsius. This means that it can be successfully applied both on the facades of buildings and on various communications located in the open air.

A simple example: if you paint pipes that run outdoors and provide hot water to the population, then the temperature in the pipe can increase by as much as 6-7 degrees!

By the way, domestic builders are already successfully using energy-saving paint in action. As an experiment, a microdistrict in Kazan was allocated. In the city, according to the state program, 15 residential buildings were insulated with paint. And it is worth noting that the energy savings turned out to be significant!

The principle of the paint is clearly shown in the photo:

Advantages of paintwork material

In addition to the fact that paint can significantly save on heating costs, it is an excellent protector of surfaces from corrosion. Also, the paint does not allow moisture to penetrate inside. And some more important advantages:

1. The paint has a beautiful sheen, and thus increases the attractiveness of the treated surface.
2. Does not cause allergies and is quite easy to use.

What the paint looks like, you can see in the photo:

About cons

The most significant drawback of paint is its high price, high consumption. In addition, heat-insulating paint cannot be used in an airtight room that is well heated, as the room will be unbearably hot.

About diversity

A fairly large number of paints from different manufacturers are presented on the construction market. Paints are also classified by types and varieties. But most of them have a single component: ceramic or glass microspheres.

Also in the composition of the paint there is a special putty with the effect of warming. By the way, in addition to the paint, you can purchase special ceramic-based additives that can be added to the paint to enhance the heat-saving effect. This type of additive looks like an ordinary white powder, consisting of small "balls" - granules. The mixture is environmentally friendly and does not contain harmful impurities. The powder melts at a temperature of more than 1600 degrees, which indicates that when paired with paint, higher heat retention rates can be achieved.

Scope of paint

Heat-saving paint, which covers the walls of buildings, is universal. Such building paint can be mixed with different types of building mixtures that are used as a finish. And this is not the whole list of materials that retain heat. In addition to paint, there are special wallpapers on sale that will save twice as much heat. If the outside of the building is covered with a special layer of plaster, and three layers of exterior paint are applied to the walls, then heat-saving wallpaper will keep the heat in the room from the inside.

The principle of heat-protecting paints is that in winter, a coating of such paint will keep the heat in the room, and in summer, on the contrary, it will not let hot air inside.

Paint is widely used not only as a protective coating for the walls of buildings, its scope has expanded significantly in recent years and is used:

• for painting the roof;
• fences;
• cornices, balconies and loggias;
• showers and other rooms that are not heated;
• pipeline pipes;
• bridges;
• storage tanks for water, gas and other flammable liquids.

Energy-saving paint has a relatively wide range of applications due to its economic effect. The service life of a surface painted with energy-saving paint is up to ten years.

During the period of growth in energy resources, energy-efficient technologies are developing by leaps and bounds. People try to get the maximum benefit out of every calorie of heat, so preventing heat loss in the first place is one of the most important tasks. One of the actively promoted novelties is energy-saving paint.

What is the essence of the action of energy-saving paint

The basics of this technology were developed in the 70s in the USA. NASA used a similar dye to insulate the outer surfaces of the Space Shuttle. The main function of such a coating is to retain the heat of the surface on which it is applied. Now it is increasingly used in everyday life, construction, industry, housing and communal services.

In fact, the paint is a set of hollow ceramic and silicone balls ranging in size from 10 to 200 microns, which are present as a suspension in a liquid mixture consisting of acrylic polymers, pigment and synthetic rubber. Due to this composition, the mixture covers surfaces of any configuration well, is extensible and light. The size of the balls determines the content of microspheres in the substance, which directly affects its properties.

After application to the surface, the suspension dries and creates an elastic coating. Energy-saving it achieves unique insulating properties due to the intense molecular effect of the air in the balls.

It can be used in many areas, in particular suitable for:

• air conditioning systems,
• pipelines,
• walls and roofs of houses,
• water heaters,
• refrigerators and freezers,
• garages,
• drinking water tanks, etc.

The composition withstands extreme temperatures up to +280 degrees, which makes it possible to use it in steam pipes, heat exchangers, boilers, pipelines with hot water.

How to apply energy saving paint

The suspension can be applied to surfaces with a paint brush, roller or sprayer. It has a very high grip rate and can be used on different types of surfaces:

• metal,
• wood,
• concrete,
• brick,
• glass,
• cardboard,
• rubber.

The dye can be diluted with water and used indoors without additional ventilation. However, for safety reasons, you should work in a respirator and goggles. The surface before painting should be degreased and cleaned, its temperature should not exceed 150 degrees, but also not be lower than 7 degrees. The temperature limits when using the material are from - 47 to + 260 degrees.

The most economical way to apply paint is with a sprayer. Then the layer thickness will be only 0.38 mm. A waterproof film appears on the surface after 15-20 minutes. The layer vulcanizes after 12 hours, and dries completely in a day. After that, you can apply the next layer.

The most effective manufacturers claim a three-layer coating. This can be checked visually: the three-layer coating has a uniform color.

Paint consumption for a single-layer coating is:

• when working with a sprayer - 0.4 l / sq.m.,
• when working with a roller - 0.5 l / sq.m.

That is, on average, one liter of a substance is enough to process 2.5 sq.m. surfaces.

The positive qualities of energy-saving paint include its incombustibility, the substance decomposes when the temperature reaches 840 degrees. This releases nitrogen and carbon, and the spread of smoke and flames slows down. The negative feature that energy-saving paint has is the price.
