SILICATE PAINT Russian patent published in 2006 - IPC C09D1/02 

FIELD: building materials industry; production of silicate paint of special composition.

SUBSTANCE: the invention is pertaining to the field of building materials industry, in particular, to the composition of the silicate paint for deposition of protective and the decorative coatings intended for staining, for example, of brick, concrete and plastered external and internal surfaces, protection of metal against oxidation and timber against putrefaction and fire. The paint contains the following components ratio (in mass %): 35.0-65.0 - modified liquid glass, 15.0-45.0 - quartz-containing component, 3.0-23.0 - talcum, 3.0-30.0 - transient oxide of s² element, 0.1-2.0 - sodium tripolyphosphate as a deflocculant, 0.01-5.0 - organic modifying agent - a copolymer, 0.001-2.5 - cellulose ether as thixotropic additive agent. As the liquid glass they use sodium glass, ammonium glass, lithium glass, potassium glass, sodium-potassium glass modified by polyorganohydridesiloxane. As the organic modifying agent- copolymer they use acrylate copolymer, or butadiene-styrene copolymer, or vinylacetate copolymer. The silicate paint may contain pigments in quantity of 0.5-15.0 mass %. The invention ensures an increased viability and storage duration of the paint, reduction of its value at keeping high parameters of its breaking away capacity, strength of adhesion, water resistance, frost-resistance and required viscosity.

EFFECT: the invention ensures an increased viability and storage duration of the paint, reduction of its value at keeping high parameters of its breaking away capacity, strength of adhesion, water resistance, frost-resistance and required viscosity.
