NOVELTY - An aqueous paint comprises component (A) comprising 45-48 %mass polyurethane emulsion, 0.1-1.0 %mass modified graphene oxide, 1.0-1.2 %mass tripropylene glycol monobutyl ether, 0.2-0.3 %mass sodium dehydroacetate, 32 %mass precipitated barium sulfate, 0.1 %mass polydimethylsiloxane, 0.2 %mass thickener and remaining deionized water, and component (B) comprising 50 %mass curing agent and 50 %mass deionized water. The volume ratio of component (A) to the component (B) is 10:1. USE - Aqueous paint. ADVANTAGE - The aqueous paint has excellent water resistance, salt spray resistance, corrosion resistance, high hardness, strong weather resistance, and excellent adhesion. The preparation process is economical due to the addition of modified graphene oxide. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the aqueous paint, which involves uniformly mixing polyurethane emulsion, modified graphene oxide, tripropylene glycol monobutyl ether, precipitated barium sulfate, polydimethylsiloxane and deionized water, carrying out grinding or high-speed dispersion to less than 40 mu m, adding sodium dehydroacetate and thickener, and uniformly stirring.
