| description | The invention discloses an anti-corrosion coating method for a metal surface. The preparation method specifically comprises the following steps: adding a silane coupling agent into a few-layer graphene aqueous solution of which the pH value is adjusted, then adding a dispersing agent, and uniformly stirring to obtain a few-layer graphene dispersion liquid; the preparation method comprises the following steps: adding graphene nanosheets and a dispersing agent into a solvent, and uniformly stirring by using high-shear equipment to obtain graphene nanosheet dispersion liquid; and adding the graphene nanosheet dispersion liquid into the primer, and uniformly mixing to obtain the anticorrosive primer. The method comprises the following steps: cleaning the surface of a to-be-coated workpiece metal, coating the surface of the to-be-coated workpiece metal with a few-layer graphene dispersion liquid, and drying to form a pretreatment layer; and the pretreatment layer is coated with anti-corrosion primer, and the anti- |
