NOVELTY - The utility model belongs to the coating technical field, especially is a graphene heavy anti-corrosion coating structure, comprising a substrate, a primer layer, a middle coating layer, top coat layer and high temperature resistant coating, the upper end of said substrate is coated with a primer layer, the upper end of the priming layer is coated with a coating, the upper end of the middle coating layer is coated with a top coat layer, the upper end of the paint layer is coated with a high temperature resistant coating, said substrate is steel or a steel structure, said primer layer is graphene/epoxy resin-based coating, the thickness is 80-120 microns. This utility model through a primer layer, a middle coating layer, top coat layer and the high temperature resistant coating, high-temperature resistant coating has high and low temperature resistance, electrical insulation, oxidation stability, and weather resistance, fire resistance, hydrophobicity, corrosion resistance, non-toxic and tasteless and physiologically inert and excellent characteristics, which further improves the service life of the base material, and it is durable, and the anti-corrosive performance, avoids the inconvenience to be periodically re-spraying.
