High hardness and high temperature resistance nanometer automobile paint belongs to the technical field of paint. The paint is prepared from, by weight, the following components: 15-25 parts of rosinphenolic resin, 1-6 parts of modified polyurethane, 2-8 parts of epoxy resin, 1-5 parts of alkyd resin, 2-5 parts of aluminum hydroxide, 3-5 parts of methyl methacrylate, 4-6 parts of antimony oxide,1-2 parts of calcium acetate, 4-7 parts of aluminum powder slurry, 6-10 parts of stearic acid, 3-8 parts of nanometer wear resistance particles, 3-6 parts of oxidized paraffin, 3-4 parts of talc powder, 8-10 parts of bismaleimide resin, 7-14 parts of ethyl acetate, 1-3 parts of additives, and 2-3 parts of initiators. The paint can withstand wiping of an acetone solvent for hundreds of times, and the solvent-resistant wiping performance is much higher than that of a commercially available product; and the paint is high in wear resistance and scratch resistance, provides good barrier protectioneffects for coated combustible materials, and enables its range of application to be greatly expanded.
