NOVELTY - The utility model model claims an anti-corrosion coating structure, comprising a zinc-rich anti-corrosion layer, the number of the zinc-rich anti-corrosion layer is two layers, a conductive layer is set between the two layers of zinc-rich anti-corrosion layer. The utility model through adding conductive layer in the two layers of zinc-rich anti-corrosion layer to form an interlayer structure, firstly, it can provide ultra-long-lasting cathode protection for the corrosion point under the extremely bad corrosion environment and long time corrosion conditions. the second conductive layer is graphene carbon nano-tube coating, the coating has a lamellar microstructure, it has the function of shielding the corrosion medium and slowing the corrosion speed. at the same time, because of the ultra-high conductive efficiency graphene the carbon nano-tube interlayer, when the zinc content of the zinc-rich anti-corrosion layer is low, the electronic movement of the zinc powder in the large range to the corrosion point through the " electronic bridge " function of the interlayer, it has excellent cathode protection effect.
