Graphene zinc coating was prepared by mixing graphene,epoxy resin,epoxy curing agent,zinc-based material,feldspar powder and other fillers with special additives in a certain proportion.The SEM was used to describe rgo zinc coating's topography and epoxy zinc rich primer and the results showed that the coating formed a compact structure with the addition of graphene.Neutral salt spray(NSS),adhesion and tafel polarization show that the graphene zinc coating has better anticorrosion performance than epoxy zinc rich primer.The dry film of graphene zinc coating containing 60%Zn and 0.5%graphene(mass fraction)exhibited the best corrosion resistance.Compared with the epoxy zinc rich primer,the neutral salt spray resistance time increased from 800 hours to 3500 hours,the drawing adhension increased from 8 MPa to 22.8 MPa,and the corrosion potential increased from 57 mV to 140 mV.The anti-corrosion mechanism of graphene zinc coating was also discussed.
