Description

The invention relates to a dispersion filler paint with a silicone component. The parba is intended for external surface treatment of the perimeter cladding of building structures in places with a high content of solid exhalations, while this paint can be applied by brush, roller or pneumatic spraying.

Previously known paints and macromolecular components produced in the form of paints have the disadvantage that they are easily contaminated with fly ash, dust, and thus suffer the color of the facades. In addition, organic binders are sensitive to oxidation in thin layers under the simultaneous action of ultraviolet rays, which, as a result of ecologically harmful earth phenomena, are increasingly reflected in paints or varnishes. coatings made from them. The survey revealed that the paint with high resistance to moisture according to the author's certificate no. 252 126 solves the increase of service life and the increase of resistance to moisture by the addition of a preservative mixture containing mineral oils and alkaline alloys of alkylairic acids. Anti-corrosion paint according to the author's certificate no. 263,431 addresses the increase in anti-corrosion efficiency by the use of core lead pigments. It follows that a specific aurovina favorably affects some vlaatnoati.

Paint aid for coloring porous and building material according to the author's introduction no. 256,009 addresses the dyeing of porous and building materials using polyalkoxyaliloxanes. It is a coloring of building material and the aid is not intended for common building substrates such as concrete, plaster, plasterboard, etc.

The invention SU 812-814 solves a paint for surface and decorative protection of reinforced concrete, asbestos cement and bricks, with the filler alumina-silica AlgO 2 -SiO ₂ being modified with dimethyldichlorosilanol, thus ensuring greater permeability to water vapor.

The said dispersion is removed by a disperse filler and an silicone component based on a copolymer macromolecular diaper, pigments, fillers, silica fillers, a solution of silicone resins or emulsions, additives according to the invention, the data of which is to contain 20 to 35 parts by weight of copolymer or styrene-acrylate diaperesis, 1 to 20 parts by weight of fillers, and preferably float, kaolin, talc, blancfix, limestone, 0.2 to 20 parts by weight of color pigments or pigment pins, 20 to 50 parts by weight of tritoate mineral silica fillings. .05 mm to 0.30 mm, 0.5 to 5 parts by weight of heat-treated silica lava peak - perlite, 0.2 to 5 parts by weight of silicone binder, preferably methylphenyl silicone resin or aqueous emulsion, 1 to 12 parts by weight of water, 0.1 to 2 parts by weight of modifiers and preferably bentonite, 5 to 15 parts by weight of additives from acupine including defoamers, diape detergents, preservatives and biocides, corrosion inhibitors, co-agents, thickeners and theological agents, wetting agents.

The created colored surface has a uniform structure, good physical and mechanical properties, such as covering, adhering to concrete, watertightness on a low substrate, diffusion.

It has been found that the addition of silicone solution resins or silicone aqueous emulsions aa increases the service life of the coating material, while maintaining a lasting hydrophobic effect and thus the purity and color of the façade. The suitable composition of the filling has a favorable effect on the diffusion properties, so that said color can be applied to all kinds of circumferential skins without creating an active vapor barrier.

The preparation of the paint is carried out by adding pigments, fillers, silica fillers, lava sands and finally organic silicone compounds to the mixture of additives, water, dispersions. The production process is completed by homogenization, after which the paint is filled into packaging.

The subject matter of the invention is evidenced by exemplary embodiments, where the stated amounts denote lengths by weight.
