▎ 摘　　要

NOVELTY - Aqueous graphene- based anticorrosive paint comprises 30-80 pts. wt. aqueous epoxy emulsion, 15-30 pts. wt. first modified graphene oxide, 15-30 pts. wt. second modified graphene oxide, 20-40 aqueous epoxy resin, 1-10 pts. wt. emulsifier, 1-15 pts. wt. curing agent, 0.1-10 pts. wt. wetting agent, 0.1-10 pts. wt. dispersant, 10-30 pts. wt. pigment filler, 0.1-30 pts. wt. co-solvent. The first modified graphene oxide is obtained by functional modification of graphene oxide with small molecules of polyetheramine. The second modified graphene oxide is obtained by modifying graphene oxide with silane coupling agent 3-Aminopropyltriethoxysilan. USE - The paint is useful for electric network facilities, ship heavy anti-corrosion, marine engineering and petrochemical industry field (claimed). ADVANTAGE - The paint: has environmentally-friendly, low spatial porosity and maintains good adhesion and corrosion resistance.
