NOVELTY - A paint comprises component (A) and component (B) in the mass ratio of 30-40:1. The component (A) includes 1 pt. wt. polyetheretherketone-acrylic modified epoxy resin, 3-4 pts. wt. sucrose polyester modified epoxy resin, 1-2 pts. wt. aliphatic glycidyl ether modified alkyd resin, 0.8-1 pt. wt. aqueous fluorocarbon resin, 2-3 pts. wt. polymethyl methacrylate, 1-2 pts. wt. silica-coated porous graphene, 0.1-0.2 pt. wt. sodium dodecyl sulfonate and 30-40 pts. wt. water. The component (B) includes 1 pt. wt. caprolactam monomer, 0.2-0.3 pt. wt. ethylene-acrylic acid copolymer and 0.03-0.04 pt. wt. catalyst. USE - Paint for automotive coating. ADVANTAGE - The coating film has excellent adhesion on the surface of the automobile and has excellent corrosion resistance to meet the automobile. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) preparation of paint, which involves (1) adding sodium dodecyl sulfate to the reaction vessel containing water, stirring and dissolving, then adding polyetheretherketone-acrylic modified epoxy resin, sucrose polyester modified epoxy resin, aliphatic glycidyl ether a modified alkyd resin, aqueous fluorocarbon resin and polymethyl methacrylate, stirring for 30-40 minutes, adding silica-coated porous graphene, stirring reaction to obtain component (A) and (2) using caprolactam monomer and ethylene-acrylic acid copolymer as raw material, carrying out polymerization reaction under the action of catalyst to obtain a modified polyamide as a component (B); and (2) method of using paint, which involves mixing and stirring component (A) and component (B), evenly spraying on the surface of the automobile, and drying at room temperature.
