Abstract
This invention relates to a zinc-rich epoxy anti-corrosion coating comprising a component A capable of being cured into a film, and a component B containing a curing agent, wherein the component A comprises, by mass percentage, 0.1-5 wt % graphene, 0-35 wt % zinc powder, 30-70 wt % filler, 10-20 wt % epoxy resin having 54 wt % solid content, and 10-20 wt % solvent, wherein the sum of the mass percentage contents of the graphene, zinc powder and filler is 60-80 wt % and the sum of the mass percentage contents of all components of component A is 100 wt %. According to the present invention, the addition of graphene to an anti-corrosion coating decreases the thickness of the coating film, reduces the amount of zinc powder while increases the anti-corrosion effect. It reduces zinc oxide vapour generated during welding and is environmentally friendly.
