NOVELTY - Waterproof coating comprises A component and B component, where the A component comprises 40-70 wt.% cement, 15-35 wt.% shell powder, 5-10 wt.% modified graphene oxide loaded with yttrium oxide, and 10-25 wt.% tourmaline powder, the component B includes 60-80 wt.% modified styrene-butyl acrylate-acrylic acid copolymer emulsion, 5-10 wt.% styrene-butadiene emulsion, 0.1-0.5 wt.% defoamer, 1-5 wt.% emulsifier, and water (balance). USE - The waterproof coating is used for construction. ADVANTAGE - The waterproof coating: contains modified styrene-butyl acrylate-acrylic acid copolymer emulsion and styrene-butadiene emulsion, which improves the fluidity and weather resistance of the coating; modifies styrene-butyl acrylate-acrylic acid copolymer emulsion, in the modification process, oleic acid-sodium lauryl sulfate modified titanium dioxide participated in the emulsion copolymerization reaction process, which improves high-temperature storage stability of the waterproof coating, and coating still exhibits excellent mechanical properties even after being stored in an environment of 50°C for a long time. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing waterproof coating, comprising (i) adding cement, shell powder and modified graphene oxide loaded with yttrium oxide into a ball mill, and ball milling and mixing to obtain component A, (ii) mixing the modified styrene-butyl acrylate-acrylic acid copolymer emulsion, styrene-butadiene emulsion, defoamer, emulsifier and water, stirring to obtain component B, and (iii) mixing component A and component B uniformly to obtain waterproof coating.
