▎ 摘  要

NOVELTY - Environmentally-friendly and corrosion-resistant aqueous graphene coating comprises 15-35 wt.% resin base material, 20-40 wt.% pigment, 0.01-0.5 wt.% graphene, 5-18 wt.% additive and 5-15% organic polyamine compound and remaining is solvent. USE - Environmentally-friendly and corrosion-resistant aqueous graphene coating used for vehicles, rails and other substrates with harsh environmental requirements. ADVANTAGE - The method uses carboxyl modified graphene to improve adhesive force between the coating and a base material, improves the mechanical property and the corrosion resistance of the coating, improves the stability, so the base material coated by the coating is not easy to peel off, does not easily rust and does not produce snail patterns. The coating has excellent stability, corrosion resistance, tolerance, ultraviolet resistance and weather resistance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation of the environmentally-friendly and corrosion-resistant aqueous graphene coating, which involves stirring the resin base material at 1000-1500 rpm, adding additive and solvent, continuously stirring, adding graphene, pigment and organic polyamine compound, mixing and stirring for 20-40 minutes, filtering the mixture and discharging.
