▎ 摘　　要

NOVELTY - An anticorrosive primer comprises 0.2-5% graphene filler and remaining zinc-rich primer. The graphene is treated with metal modifier. The metal modifier is chosen from one or more of metal, metal doping, nano metal oxide, and nano metal oxide doping. The amount of metal modifier is 10-50% mass ratio of graphene. USE - Anticorrosive primer for bridges. ADVANTAGE - The anticorrosive primer provides adhesion between primer and graphene is improved. Reduce its structural defects, enhance adhesion of coating thereby forming dense protective film and improve corrosion resistance.
