▎ 摘　　要

NOVELTY - Graphene oxide aqueous epoxy coating comprises 26 wt.% epoxy resin, 16 wt.% curing agent, 50 wt.% zinc powder, 5.8-6.4 wt.% mica powder, 0.4 wt.% wetting agent, 0.4 wt.% defoamer, 0.2 wt.% anti-flash rust agent, 0.2 wt.% leveling agent, 0.4 wt.% anti-settling agent, 0-0.4 wt.% graphene oxide and 0-0.2 wt.% dispersant. USE - Graphene oxide aqueous epoxy coating. ADVANTAGE - The graphene oxide aqueous epoxy coating plays the dual functions of physical shielding anticorrosion and electrochemical effect anticorrosion, greatly improves the anticorrosion effect, preparation process is simple, the operation is easy, the equipment requirements are not low, the environment is friendly, and suitable for industrial production. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing graphene oxide aqueous epoxy coating, which involves dispersing aqueous epoxy resin, wetting agent, defoaming agent, anti-flash rust agent, leveling agent and anti-settling agent for 5 minutes, then adding mica powder, graphene oxide and dispersant, continue to stirring and dispersing for 10 minutes, adding zinc powder at a speed of 300 revolutions/minute, and continue to stirring and disperse for 15 minute at a speed of 1500 revolutions/minute after adding zinc powder, adding quantitative curing agent to the dispersion mixture, stirring and dispersing uniformly, adding water to dilute, and coating the tinplate sheet with a 150 micrometer wire rod coater, drying and curing at room temperature for 7 days, and obtaining a graphene oxide aqueous epoxy coating.
