▎ 摘　　要

NOVELTY - Coating comprises graphene, conductive ceramic powder, aqueous resin, inorganic acid, auxiliary agent and solvent, where the coating is formed by curing. USE - Used as coating. ADVANTAGE - The coating has good and stable adhesive force and toughness, long-term use will not happen cracking and shedding phenomenon, good resistance stability, good heating performance, strong high temperature resistance and long service life, and wide application prospect in the field of heating coating. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the coating, comprising (i) orderly adding graphene and conductive ceramic powder into the solvent to disperse and grind, adding auxiliary agent and inorganic acid and adding aqueous resin to obtain the graphene composite coating; and (ii) coating the graphene composite coating on the substrate, heating and curing to form the coating.
