▎ 摘  要

NOVELTY - An aqueous coating comprises component (A) comprising 1-5 pts. wt. graphene, 0.1-2 pts. wt. crosslinking agent, 2-5 pts. wt. water-soluble negative ion additives, 15-20 pts. wt. silicone resin and 10-15 pts. wt. inorganic silicate and component (B) comprising 50-80 pts. wt. aqueous epoxy resin and 2-4 pts. wt. amine compound. USE - The aqueous coating is used in automobile paint (claimed). ADVANTAGE - The aqueous coating has good corrosion resistance, stability and good mechanical properties, and achieves self-drying effect within 30 minutes. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation method of the aqueous coating comprising (S1) mixing graphene crosslinking agent and water-soluble negative ion additives to obtain the component (A), (S2) mixing aqueous epoxy resin and amine compound to obtain the component (B) and (S3) mixing component (A) and component (B) to obtain the aqueous coating.
