SILICATE PLASTER MASS, LIGHT PLASTER CONSISTING OF THIS SILICATE PLASTER MASS, AND USE OF SAID SILICATE PLASTER MASS TO PRODUCE LIGHT PLASTERS Russian patent published in 2019 - IPC C04B41/48 C04B26/00 C04B14/04 C04B14/16 C04B14/24 C04B16/08 

FIELD: chemistry.

SUBSTANCE: group of inventions relates to silicate plaster mass. Silicate plaster coating contains: at least one silicate filler, wherein silicate filler has bulk density higher than or equal to 2.0 kg/l, and average particle size D₅₀ not more than 250 mcm; at least one light filler, wherein the light filler has bulk density lower than or equal to 1.0 kg/l, and the average particle size D₅₀ not more than 250 mcm; silicon sol; at least one liquid glass; granular material, wherein grain size of granular material defined by sieve analysis according to DIN 66165 is at least 300 mcm; at least one organic binder comprising at least one dispersed or dispersible polymer formed from monomers of one type or from different monomers, wherein at least one of the monomers is selected from a group consisting of vinyl acetate, vinyl chloride, vinyl propionate, ethylene, acrylonitrile, methacrylic acid ester, acrylic acid ester, butadiene, styrene, versatate and maleate ester, and/or at least one organosilicate hybrid binder; additives and water, plaster mass having pH value of at least 9.5, in particular of at least 10.5.

EFFECT: technical result is prevention of efflorescence and defeat of algae and fungi, resistance to weather factors, low flammability, high adhesion of sublayer plaster mass, low weight of plaster mass, reduced consumption of plaster mass.
