▎ 摘　　要

NOVELTY - Anti-corrosive coating comprises (in pts.wt.): antirusting agent and graphene or graphite-based oxide, where antirusting agent is doped in graphene or graphite-based oxide. USE - Anti-corrosive coating used for building, bridge, industrial device, metallurgy, mold, shipping, communication device and traffic tool. ADVANTAGE - The anti-corrosive coating has wide inustrial applicability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing anti-corrosive coating, which involves (A) mixing graphite oxide and organic solvent to obtain a graphite oxide solution; and (B) adding graphene or a graphite oxide doping agent in the graphite oxide solution, and then mixing antirusting agent and alkenyl-substituted resin paint by using an ultrasonic oscillator to obtain the final product.
