The invention discloses catalytic oxidation paint used for an automotive alternator cover plate. The catalytic oxidation paint is prepared from the following raw materials in parts by weight: 22 partsof nano material level organic silicone modified acrylic emulsion, 15 parts of polyurethane acrylate, 20 parts of 1000-mesh calcium carbonate, 8 parts of 1500-mesh talcum powder, 18 parts of rutile titanium dioxide, 5 parts of bismaleimide, 5 parts of neopentyl glycol, 15 parts of hydroxyethyl cellulose, 8 parts of methyl silicone oil, 5 parts of titanium dioxide, 3 parts of carboxylic acid, 14 parts of purified water, 3 parts of mixed type lead-free boron-free glass powder, 6 parts of an adhesion promoter, 4.8 parts of organosilicone-modified polyurethane and 5 parts of core-shell type magnesium fluoride micro powder. The catalytic oxidation paint disclosed by the invention has the advantages that a film of the coating is compact and rigorous, color does not bleed, the film is not cracked or expanded and is not peeled under intensive ultraviolet rays, drying time is short, ultraviolet lamp radiation is combined during spraying, and adhesive force of the paint on the cover plate is better.
