NOVELTY - Graphene oxide aqueous epoxy coating comprises 6-10 wt.% aqueous epoxy curing agent, 0.15-1 wt.% modified graphene oxide dispersion, 10-15 wt.% antirust pigment, 15-30 wt.% coloring pigments and fillers, 10-30 wt.% deionized water, and 1-4 wt.% auxiliary as component A, and a non-ionic aqueous epoxy emulsion component B. The solid content is 40-60%, and the addition amount of the B component is 35-45% of the total mass of the coating. The modified graphene oxide is a reactive halogen-free flame retardant curing agent modified graphene oxide. USE - The aqueous epoxy coating is useful for ships. ADVANTAGE - The method is simple, free of organic solvents, safe, environmentally friendly and non-toxic. The cured paint film has excellent comprehensive properties, high performance and high environmental protection requirements and is suitable for the construction and application of marine coatings in marine environments.
