The invention relates to high-performance water-based heavy anti-
corrosion paint and a preparation method thereof, and belongs to the technical field of water-based anti-
corrosion paint. The water-based heavy anti-
corrosion paint comprises water-based
epoxy zinc rich primer, water-based
epoxy graphene-modified intermediate paint and water-based
polyurethane finishing paint, wherein an intermediatecoating uses the water-based
epoxy graphene-modified intermediate paint; properties, such as an extra-large specific surface area, good barrier property, high
chemical stability and good electrical
conductivity, of
graphene are utilized, so the overall performance of the anti-corrosion compound
coating is greatly improved, for example, an
adhesive force of the
coating to a base material is reinforced, the
abrasive resistance and the anti-corrosion property of the paint are improved, and the
coating has the characteristics of
environmental protection and safety, and no secondary
pollution andthe like. Three types of the paint are compounded for using, a thickness of a paint film can be greatly reduced under the
precondition without affecting the anti-corrosion property, and the requirements of lightweight coating are satisfied. The preparation method of the water-based heavy anti-corrosion paint is simple, and suitable for industrial production, and raw materials are easily obtained.
