Abstract
A low-VOC-emission waterborne coating is prepared from a waterborne acrylic emulsion, a hydrophilic cross-linking agent, a coalescing agent, additives and a pigment, and the waterborne acrylic emulsion is formed from performing emulsion polymerization on those reactive monomers including an alkyl-group-containing methyl acrylate, a hydroxyl-group-containing methyl acrylate, a carboxyl-group-containing methacrylic acid, a hydroxyl-group-containing acrylic polyester (polyether) polyol, and a methyl acrylate containing alkene-based unsaturated functional groups, which features high hardness, good adhesion, high luster, high acid resistance, high alkali resistance, good weatherability, high solvent resistance, high scrap resistance and high thermal shock resistance.
