Energy-saving paints: what they are and how they are used. What is energy-saving paint Energy-saving paint for glass

Modern consumers are accustomed to a variety of paints and varnishes. And even today, some of them are surprised that there are not only simple paints, but also energy-saving ones.

What are the features of this material and how exactly is it used? If you know as fully as possible about the qualities of energy-saving paints, you will be able to significantly improve your living conditions without resorting to complex technologies.

What is energy-saving paint?

Structurally, energy-saving paint is a so-called polymer matrix. It contains great amount microscopic pores, which reduce heat loss. The material is produced in the form of a fine powder. Moreover, the particles themselves are so small that their diameter rarely exceeds 50 microns. Due to such a specific structure and interesting looking polymer paint and is endowed with excellent thermal insulation parameters.

Where are energy-saving paints used?

The scope of application of the material is even wider than that of ordinary paint. It is clear that it can be used to paint walls, ceilings, and floors. But, in addition, it is suitable for painting cornices, loggias, heating pipes and water pipes. It is actively used at industrial facilities, warehouses, and hangars. Railroad and automobile tanks, which transport materials that are sensitive to temperature changes, are also covered with it.

Energy-saving paint is mainly used for external works. But internal use is also possible. The material is safe, so it is recommended for use even in baths and saunas. Energy-saving paint is not afraid of heat. And in terms of environmental friendliness, it is no worse than other paints and varnishes.

How to handle energy-saving paint

Exist various methods applying this composition to the work surface. The most common tools are used: brush, roller, spray bottle. To save material, it can be added to other paints. There are no special requirements for the base for painting. The material fits equally well on plaster and painted wallpaper.

In the seventies, American scientists were tasked with developing a special material for spaceships, which could withstand both extremely high and very low temperatures. The created composite material, consisting of a polymer matrix and a special filler, is called energy-saving paint. The topical issue of energy saving these days has literally forced energy-saving paints to fall from heaven to earth. Today this modern material effectively used for “domestic” purposes as a thermal insulating coating for enclosing structures and pipelines.

Operating principle

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

The secret of the energy-saving properties of the coating is as follows. After drying, the composition turns into a dense and elastic membrane. Microspheres located in the membrane are capable of reflecting and scattering about 90% of infrared radiation and more than 80% of visible sunlight. Energy saving paint- this is a kind of “climate control” that does not allow heat into the house in the summer, and in the winter it keeps the heat inside and is a barrier to the street cold. In numerical terms, the reduction in heat loss from enclosing structures 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;
• premises with high humidity and poorly heated rooms (bathrooms, toilets, showers, locker rooms, etc.);
• external and internal surfaces of enclosing structures of buildings and structures for industrial purposes (workshops, warehouses);
• external and internal surfaces of enclosing structures of public buildings (stations, gyms, 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 storing oil, petroleum products, gas, water;
• bridges.

Energy-saving coating reduces heat loss, protects structures from corrosion and overheating, prevents the formation of condensation, reduces operating costs and reduces the need for renovation work. In addition, energy-saving paints, along with high functionality, look quite aesthetically pleasing and are perfect for finishing buildings.

On average, energy-saving paints from various manufacturers can 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, be it concrete or Brick wall, metal pipe, wooden or plasterboard partition. In this case, the surface can be of absolutely any shape - the paint will lie evenly.

How to work with energy-saving paints

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

To apply paint to the surface, use a brush, roller or spray gun. First apply one layer. The time required for drying is 24 hours, then polymerization occurs within 12 hours (the same membrane is formed). After this, it is necessary 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 structures and does not occupy usable area, in contrast to the use of multilayer insulation.

Energy-saving paints must be thoroughly mixed in a bucket or some other container before application. You can use an electric drill with a special attachment for this. There is no need to dilute the paint with water - it is sold ready-made.

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

Caring for painted surfaces is very simple - they can be washed with any detergents. If there is a need to replace the coating, this can be done using grinding tool. But it should be noted that the paint has quite long term services. Manufacturers usually provide a warranty of at least 10 years. But, as experience shows, on the external surfaces of house structures it should work reliably for up to 50 years in ordinary Russian climatic conditions and up to 15 years if exposed to harsh environmental influences.

New trends and developments

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

Recently, a fundamental new product appeared on the market - a ceramic additive that can be mixed with regular paint, turning it into energy-saving. Eco-friendly and non-toxic dry powder, consisting of ceramic granules, is added to paint at the rate of 110 grams of additive per 1 kg of paint. The additive can also be used with other coatings and composite materials for interior and exterior finishing premises.

But this invention is not the limit. Science has moved on, and today, based on energy-saving additives, they produce energy saving wallpaper, which are glued under ordinary ones. In addition to performing thermal insulation functions, they also smooth out unevenness on the wall well.

Effect in numbers

The reduction in 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 thermal insulation materials.

What is energy saving paint

Energy-saving paints are a new generation of special composite materials. It was invented by designers assembling space shuttles back in the 70s of the last century. As main characteristics Such paints were designed to be highly resistant to high and low temperatures. This is how they appeared energy saving paints, which were a special polymer matrix filled with special hollow microscopic particles. The particles are microspheres, according to appearance resembling powder. The diameter of one sphere can range from 10 to 200 microns. From this indicator, as well as the percentage of microspheres in the composition will determine the main characteristics of the paint.

In the 80s and 90s of the last century energy saving paints began to be used in other areas besides rocket science. Based on them, a special thermal insulating coating based on liquid polymer materials began to be produced.

At the end of the 20th century, this type of paint appeared on the consumer construction market, where it remains to this day.

Modern energy saving paints

Today, there are energy-saving paints from many manufacturers, types and varieties.

Most modern paints of this type contain special microspheres made of ceramic or glass. Spherical fillers are developed and manufactured using the latest nanotechnology. Modern paint also includes a special insulating putty.

In addition to the paints themselves, today you can also purchase special additives made in a similar way. Ceramic energy-saving additives should be added to ordinary paint, giving it enhanced thermal insulation characteristics. The additive is produced in the form of a white dry powder, at detailed consideration which you can see a lot of small ceramic granules. This building mixture is environmentally friendly pure material and does not contain any harmful toxic impurities. The melting point of granule-based powder is 1800 degrees Celsius. Thanks to this property, when powder is added to paint, the latter acquires high, permanent heat-saving indicators.

Energy-saving wall paint and others are capable of using it

The energy-saving additive is a universal mixture, and therefore it can be mixed not only with ordinary paint, but also with many other types of coatings and composite materials that are used for finishing works different types. Based on energy-saving additives and polymers, special wallpapers are also produced that can retain heat in your home. You can use such wallpaper as usual, or stick it under existing wallpaper. The coating will help increase the thermal insulation of the room, and also make the walls smoother and more even.

This is achieved by polymerization of the additive composition. After complete drying, the entire mass is a dense and fairly durable monolith that does not allow heat to pass through, infrared radiation, as well as solar ultraviolet radiation. In fact this type coverage is ideal both in summer and winter. During frosty periods, the coating will prevent heat from leaving the room, and during hot periods it will prevent stuffy air from coming inside.

Today's area of ​​use energy-saving paints wide enough. Firstly, these paints and additives are indispensable when repairing house facades, treating external surfaces and roofs. This paint can be used to paint a balcony, loggia, cornices and any other external structures for domestic or industrial purposes.

For interior decoration are used energy saving paints for walls.They are ideal for bathrooms, saunas, swimming pools and other rooms with high humidity. An extremely wide area of ​​application for such paints and compositions is industrial. Such paints are indispensable for the construction of workshops of factories and factories, metal structures, premises social purpose, roofs of buildings and hangars. The paint is used for painting storage tanks for petroleum products, liquids or gases.

So wide scope applications these colors exists due to the large number of positive properties of this building composite material.

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

The main function of such paint is to retain as much heat as possible of the surface on which it is applied. This paint is a new generation product. The history of such paints is mentioned back in the 70s, when the need arose to insulate outer surface spaceships. Then well-known company Nasa has developed such material. Subsequently unique paint began to be used for different areas activities. 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 from 10 to 200 microns. By the way, the percentage of microspheres 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 quite recently in Russia they began to produce similar paint for use in housing and communal services.

Despite the fact that on Russian market There is a wide selection of various heat-saving materials, in particular, insulation; paint is the only unique material that does not allow the cold to pass through from the outside of the building. It works on the principle of storing heat that leaves the room and then releasing it back.

Important: heat-saving paint works well in combination with a heated floor, which has an infrared film structure. Thus, when a heated floor is installed in a room, the heat will not penetrate into the lower rooms, but will be returned 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, paint is applied to the surface in the same way as ordinary paint using a roller, brush or a special device with a sprayer. Paint with an energy-saving effect has excellent adhesion properties. It easily covers any surface:

• tree;
• 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 three-layer coating. If the consumer wants to save money, and it is worth noting that the price of paint is quite high, then he will not get the desired effect of preserving heat in the room. By the way, this indicator is easy to check: 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 there is no point in talking 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. The paint can be applied in any way. After applying the first layer, after ten minutes a thin film forms on the surface, which dries within 24 hours. And only after the first layer has completely dried, the next layer is applied.

The paint consumption when working with a roller is half a liter per square meter, and with a sprayer it is one hundred grams less. One liter of paint allows you to cover about 2.5 square meters area.

Paint in action

Paint with an energy-saving effect does not deteriorate when exposed to high temperatures. It can withstand maximum temperatures up to 250-260 degrees Celsius. This means that it can be successfully used both on the facades of buildings and on various communications located in the open air.

A simple example: if you paint pipes running outdoors and providing hot water to the population, 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 selected. In the city, according to state program, 15 residential buildings were insulated with paint. And it is worth noting that energy savings turned out to be significant!

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

Advantages of paint and varnish 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 a few more important advantages:

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

You can see what the paint looks like in the photo:

About the cons

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

About diversity

There are enough presented on the construction market a large number of paints from different manufacturers. Paints are also classified by type and variety. But most of them have a single component: microspheres made of ceramic or glass.

The paint also contains a special putty with a warming effect. By the way, in addition to paint, you can purchase special ceramic-based additives that can be added to the paint to enhance the heat-saving effect. This type The 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 suggests that when paired with paint, higher heat retention rates can be achieved.

Paint application area

Paint with a heat-saving effect, which covers the walls of buildings, is universal. Such construction paint may mix with different types building mixtures which are used as finishing. And this is not the entire list of materials that retain heat. In addition to paint, there are special wallpapers on sale that will retain 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 inside Heat-saving wallpaper will keep the room warm.

The principle of heat-protecting paints is that winter period A coating of such paint will keep the room warm, and in the summer, on the contrary, it will prevent hot air from getting inside.

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

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

Energy-saving paint has a very 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.
