▎ 摘　　要

NOVELTY - Graphene heavy-duty anticorrosive coating comprises a resin system and a curing agent system, where the resin system comprises 0.82-1.5 parts mass modified graphene, 70-80 parts mass epoxy resin, 13-28 parts mass first organic solvent, 1-2 parts mass binder, and 5-7 parts mass leveling agent, and the mass ratio of the curing agent system to the resin system is (3.5-4.5):1. USE - The coating is useful as a heavy duty anticorrosive coating (claimed). ADVANTAGE - The graphene heavy-duty anticorrosive coating has excellent anticorrosive performance and mechanical properties. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the coating, comprising preparing the resin system and curing agent system, where the step of preparing the resin system involves preparing modified graphene, uniformly mixing modified graphene, epoxy resin, and first organic solvent to obtain a first mixture, uniformly mixing the first mixture, binder, and leveling agent to obtain a second mixture, and ultrasonically processing the second mixture.
