The waterborne zinc-rich epoxy primer greatly reduced the emission of volatile organic compounds(VOC), but its anti-corrosion performance is still difficult to reach the level of solvent-based zinc-rich epoxy primer. A low zinc content graphene waterborne zinc-rich epoxy primer with 3 000 hours salt spray resistance was prepared by controlling the molar ratio of reaction groups of epoxy resin and modified amine curing agent was 1.2∶1, the content of zinc powder in dry film was 60%, the content of graphene was 0.25% and the pigments volume concentration(PVC) was 40%.
