▎ 摘  要

NOVELTY - Graphene aqueous anticorrosive coating includes a base resin component and a curing component. The mass ratio of the basic resin component and the curing component is 1:(1.5-3.5). The curing component includes at least 50-100 pts. wt. of flake zinc powder, 5-20 pts. wt. graphene, 100-250 pts. wt. curing agent, 1-2.5 pts. wt. polyether modified siloxane and 150-200 pts. wt. water. USE - Graphene aqueous anticorrosive coating. ADVANTAGE - The graphene aqueous anticorrosive coating has good dispersibility, and the gloss and uniformity of the coating are good, the coating toughness is high, the coating adhesion is significantly improved, and the salt spray resistance effect can be greatly improved, and zinc powder in the synergistic system increases its utilization rate, strengthens the cathodic protection of zinc powder, and achieves the best corrosion resistance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for using the graphene water-based anticorrosive coating, which involves: (A) degreasing the surface of the workpiece to be coated, and then derusting, removing oil, salt and other dirt, then brushing; (B) stirring the basic resin components uniformly, then mixing the curing components with them, and stirring them uniformly; (C) adding 0-15 wt.% of thinner, then waiting for the graphene aqueous anticorrosive paint to mature before painting, and during construction, the surface temperature of the workpiece must be 3 degrees C higher than the dew point temperature and lower than 50 degrees C; (D) stirring the brushing operation to prevent precipitation; and (E) spraying and brushing the painting, and total thickness of the primer film layer is 60-80 micrometer, and it is applying in two coats, and after it dries, painting the topcoat on the surface of the film.
