Description

The mixture is designed for thermal insulation of interiors and exteriors of buildings

BACKGROUND OF THE INVENTION

Older types of thermal insulation materials such as polystyrene and polyurethane, mineral wool, expanded perlite, etc. are used in building technology to reduce heat transmission through walls and ceilings of buildings. Their main disadvantage is the layer thickness, which significantly increases the overall thickness of masonry, up to tens centimeters, which in architecturally and historically valuable buildings with a significant relief of external or internal plaster would lead to degradation of the building. This type of insulation cannot be used even if the building is already finished and has a finished facade.

By using common internal insulation, the inner space is significantly reduced.

In the case of older buildings and buildings used only occasionally, the negative factor of these standard insulation is the purchase price in relation to the service life of the building or the rate of its use.

It should not be forgotten that the frequent undesirable phenomenon that arises when these conventional insulations are used in conjunction with plastic window frames is the increased humidity of the masonry and consequently the formation of mold.

In addition to these older types of thermal insulation materials, composite materials with a thickness of approximately 8 mm of thin insulation and thermo-reflective foil are newly used in the construction industry, but they can only be used in a small area, eg behind a heating element.

In recent years, thermally insulating coatings have been developed and used, reminiscent of conventional interior plasters, which are applied at a thickness of 1 to 2 mm. In addition to organic polyacrylate or polyvinyl acetate binders, they contain hollow glass microspheres as the main component and an airgel that fills the interspace between the beads. Other components are antifungal, flame retardant, stabilizer, dispersant, etc. They can be applied to masonry, wood and metal surfaces by painting or spraying.

The main drawback of these materials is their soft surface, which is easy to rub off, for use as an internal plaster. They are therefore very resistant to mechanical wear on the surface.

Another major drawback is the low heat resistance, which ranges only from -40 ° C to +150 ° C. Because of the use of organic binders and organic antifungal, these coatings are subject to destruction at temperatures above +150 ° C, making their application in the region impossible. for hot surfaces such as pipes, furnaces, boilers.

For these reasons, the existing mixtures do not sufficiently meet the fire performance when applied to wooden buildings and wooden attic spaces.

The essence of the technical solution

The new compound has significantly better properties than the existing materials due to its completely different composition. It uses balls with an ideal distribution curve to ensure optimal insulation environment inside the mixture. In addition to previously used glass or ceramic hollow microspheres, it also uses new types of glass foamed glass spheres, these porous spheres have a surface treatment that increases stability, have a low thermal conductivity coefficient, a high temperature resistance of 900 ° C, and chemically and mechanically very durable.

The used binder-potassium water glass (aqueous solution of potassium silicate) -is purely inorganic origin, has thermal insulating properties, further anti-fungal effects (no need for additional anti-fungal preparation), it is highly non-flammable and refractory (new mixture no longer requires flame retardant) it has good adhesion to all surfaces and facilitates application to the base material, ensures sufficient hardness and abrasion resistance of the coating, as well as vapor permeability. The waterglass is stabilized with the hydrophilic alkoxy alkyl ammonium salt of Betolin Q 40.

Osakryl OSA23NM styrene-acrylate dispersion and Dispelair CF 895 antifoam are added to the blends.

The composition intended for masonry application has better thermal adhesion to the masonry, higher surface hardness and abrasion resistance, and higher grain size of the filler compared to the existing composition while maintaining thermal insulating properties, even without the use of airgel, which is expensive. so it looks like a regular stucco plaster. Coarse plaster types can also be used as external plaster.

The properties described, such as hardness and abrasion resistance, were observed after application to the perimeter wall; the originally cold wall was dry and warm. All kinds of mixtures were applied to a surface with a heat of lottery of 500 C, in the touch test the surface was only hot.
