Abstract

The invention provides a waterproof coating for an internal wall and a preparation method of the waterproof coating. The coating consists of the following components in parts by mass: 36-48 parts of water, 0.7-2.5 parts of sodium hexametaphosphate, 24-35 parts of argil, 18-26 parts of calcined kaoline, 0.9-1.8 parts of polyoxyethylene ether, 48-62 parts of styrene-acrylic emulsion, 20-30 parts of silica sol, 2.7-5.4 parts of texanol ester alcohol, 1-2.4 parts of polycarbonate, 0.5-1.2 parts of diethyl phthalate, 0.1-0.3 part of rigid polyvinyl chloride and 1.2-3 parts of sodium pentachlorophenate. The coating provided by the invention is attractive in appearance, stable in storage and proper in viscosity, has good heat resisting, freezing resisting and waterproofing functions, has excellent mildewproof and antistatic effects, and can achieve an extremely good protection effect on the internal wall.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a waterproof coating for interior walls and a preparation method thereof. Background technique [0002] Styrene-acrylic emulsion is obtained by emulsion copolymerization of styrene and acrylate monomers. It has good adhesion, transparent film, good water resistance, oil resistance, heat resistance and aging resistance. [0003] At present, the interior wall coatings used by people have excellent comprehensive properties, but their heat resistance, frost resistance, and waterproof functions are not outstanding. With the alternation of seasons, the coatings are prone to cracking and aging, and their anti-mildew and anti-static effects are poor. Contents of the invention [0004] Technical problem to be solved: Aiming at the shortcomings of the above-mentioned interior wall coatings, the present invention provides a waterproof coating for interior walls and a preparation method thereof. ...
