▎ 摘　　要

NOVELTY - A graphene composite coating comprises 15-35 pts. wt. modified graphene, 30-45 pts. wt. acrylate emulsion, 2-4 pts. wt. polycarboxylate salt dispersant, 0.5-2 pts. wt. nonionic wetting agent, 1-5 pts. wt. calcium bentonite, 12-20 pts. wt. solvent and 1-3 pts. wt. additives. The modified graphene is palladium-doped graphene. The doping molar ratio of palladium atoms in palladium-doped graphene is 0.5-2%. The acrylate emulsion is organo titanium modified acrylate emulsion. USE - Graphene composite coating (claimed). DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation method of graphene composite coating, which involves adding organo titanium modified acrylate emulsion to kettle, stirring at 1200-1500 rpm for 30-60 minutes, adding polycarboxylate salt dispersant, non-ionic wetting agent, calcium bentonite and solvent, mixing to obtain a mixed material, adding modified graphene and additives to the mixed material, heating at 60-80 degrees C for 30-40 minutes and cooling.
