▎ 摘  要

NOVELTY - A coating material comprises 8-15 pts. wt. graphene oxide, 5-10 pts. wt. copper powder, 0.3-3 pts. wt. antioxidant, 8-15 pts. wt. diatomaceous earth, 5-10 pts. wt. active agent and 20-40 pts. wt. resin compound. USE - The coating material is useful for surface treatment of automobile ferrule (claimed). ADVANTAGE - The coating material forms protective film having excellent hardness and wear resistance. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) method for preparing the coating material, which involves (a) mixing copper powder with dilute hydrochloric acid and then ultrasonically mixing with graphene oxide, and (b) mixing obtained mixture with antioxidant, diatomaceous earth, active agent and resin compound; and (2) surface treatment of automobile ferrule, which involves spraying the coating material onto a surface of an automobile ferrule by laser spraying.
