WATER DISPERSION PAINT Russian patent published in 2015 - IPC C09D133/02 C09D133/04 C09D125/08 

FIELD: chemistry.

SUBSTANCE: invention relates to paint materials, particularly water dispersion paints based on a copolymeric acrylate dispersion with addition of pigments, filler and auxiliary substances. The water dispersion paint is intended primarily for external painting of buildings and structures and contains as a pigment a mixture of titanium dioxide and titanium slag, which is an industrial waste, formed with formation of titanium dioxide in rutile form during industrial high-temperature treatment of titanium and alloys thereof, ground to a fraction of minus 60 mcm. The water dispersion paint includes a pigment - mixture of titanium dioxide and titanium slag, filler - chalk and calcite, film-forming agent - styrene-acrylate dispersion A-10, a dispersant, a thickener, an anti-foaming agent, a preservative, a coalescent and water, with the following ratio of components, wt %: pigment 10-30, filler 34-50, film-forming agent 12-19, dispersant 0.4-0.6, thickener 0.8-0.85, anti-foaming agent 0.2-0.3, preservative 0.2-0.3, coalescent 0.5-0.6, water - the balance.

EFFECT: paint formulation provides improved physical and mechanical and operational properties, particularly high water resistance, weather resistance and frost resistance.
