Abstract

The invention relates to an automobile chassis part based on an impact-resistant coating, the automobile chassis part comprises an automobile chassis part body and an impact-resistant coating, the impact-resistant coating is obtained by coating the surface of the automobile chassis part with the impact-resistant coating, and the impact-resistant coating is prepared from the following raw materials in percentage by mass: 45-49% of epoxy resin, 7-9% of a reinforcing agent and 4-6% of modified graphene oxide, the coating comprises the following components in percentage by weight: 3-5% of zinc oxide, 0.2-0.4% of dimethyl silicone oil, 0.2-0.4% of polyacrylic acid and the balance of solvent. The reinforcing agent is added into the coating, so that the impact resistance of the coating can be improved, and the impact resistance of an automobile chassis part is improved; the modified graphene oxide is added into the coating, so that the corrosion resistance of the coating can be improved, and the corrosion resistance of the automobile chassis part is improved.

Description

technical field [0001] The present application relates to the technical field of automotive chassis parts, in particular to an automotive chassis part based on impact-resistant coatings. Background technique [0002] Automobile chassis parts include rear axles, trailing arms, anti-collision bars, foot pedals, instrument panel beams, etc. The automobile chassis parts are assembled from these parts. [0003] Therefore, the inventor believes that the automobile chassis parts are relatively large in size, and are susceptible to the impact and friction of external objects during the handling process, thereby causing damage to the automobile chassis parts. SUMMARY OF THE INVENTION [0004] In order to reduce the possibility of damage to automobile chassis parts, the present application provides an automobile chassis part based on impact-resistant paint. By adding a reinforcing agent to the paint, the impact resistance of the paint is improved, thereby improving the impact resist...
