▎ 摘　　要

NOVELTY - A coating comprises 40-45 pts. wt. aqueous epoxy resin, 15-20 pts. wt. acrylic acid modified aqueous polyurethane, 18-35 pts. wt. polyethylenepyrrolidone/graphene dispersion liquid, 1-2 pts. wt. film-forming auxiliary agent, 8-15 pts. wt. curing agent, 0.5-1 pts. wt. adhesion promoter, 15-20 pts. wt. modified filler, 0.5-5 pts. wt. auxiliary agent and 60-80 pts. wt. water. USE - Coating. ADVANTAGE - The coating has good stability, abrasion resistance and corrosion resistance, and can be cured under medium and low temperature conditions, which can greatly improve drying speed. The paint film has good compactness, smoothness and flexibility, and improved strength, corrosion resistance, scratch resistance, abrasion resistance and adhesion to different substrates. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the coating comprising adding aqueous epoxy resin and acrylic acid modified aqueous polyurethane into water, stirring for 20-30 minutes, adding graphene, polyvinylpyrrolidone and modified filler, stirring for 30-60 minutes, dispersing and grinding for 60-90 minutes, adding film-forming auxiliary agent, curing agents, auxiliary agent and adhesion promoter, and stirring for 30-40 minutes.
