The invention discloses aqueous paint. The aqueous paint comprises the following materials in parts by weight: 80-90 parts of aqueous acrylic 
emulsion, 15-20 parts of light 
calcium carbonate, 8-10 parts of hydroxypropyl 
methyl cellulose, 2-3 parts of 
dibutyl phthalate, 2-4 parts of 
glycerol, 1-2 parts of glycol 
ether, 1-2 parts of 
sodium polyacrylate, 1-2 parts of buthyl polyacrylate, 2-3 parts of 
hydrotalcite, 0.2-0.4 part of dimethyl 
silicon oil, 1-3 parts of 
diphenylamine, 10-20 parts of deionized water, 0.8-1 part of N-(beta-aminoethyl)-gamma-aminopropyl trimethoxy 
silane and 10-15 parts of composite mosifying agent. The paint film produced by the preparation method disclosed by the invention is firm, good in glossiness, strong in 
impact resistance, unlikely to crack, soft in texture, strong in decoration, high in 
weather resistance, washing-resistant, strong in 
adhesive force, long in service life, free of special smell, free of 
heavy metals including mercury, lead and the like, free of 
formaldehyde volatile matter and capable of satisfying the technical requirements of environmentally-friendly paint. The conventional 
titanium dioxide is replaced by the added composite modifying agent, so that the surface gloss of the paint film is improved and the production cost is saved; moreover, the paint film has better washing resistance and 
weather resistance, and therefore, the quality of the paint film is strengthened.
