Abstract

Graphene with different specific surface areas was characterized by scanning electron microscopy, transmission electron microscopy and atomic force microscopy and so on. The effects of specific surface area and content of graphene on the corrosion resistance of water-based epoxy zinc-rich anti-corrosion coating were investigated through neutral salt spray test. The results show that the anti-corrosion coating modified by graphene had significantly improved resistance to neutral salt spray corrosion. With the increase of the specific surface area of graphene, the corrosion resistance of the coating first improved and then tended to be stable. When the specific surface area was 500 m²/g and the addition amount was 0.7%, the resistance time to neutral salt spray corrosion was over 2 000 h for the graphene modified water-based epoxy zinc-rich anti-corrosion coating.
