The steel plate corrosion prevention is mainly realized by adopting a steel surface galvanization mode at present, and a sacrificial anode plating layer is adopted to protect a steel matrix, so that the service life of steel materials is prolonged. However, zinc is very active and is susceptible to corrosion by substances or media such as acids, alkalis, oxygen, carbon dioxide and water vapor in the atmosphere, so that the zinc layer needs to be protected to some extent, i.e. passivated. The traditional passivation mode of the galvanized layer adopts hexavalent chromium salt for passivation, and the method has simple process, excellent performance and low cost, but the hexavalent chromium has carcinogenicity, and meanwhile, has great harm to the environment, so the hexavalent chromium passivation is basically forbidden.

However, the passivation performance of chromium-free at present still cannot perfectly reach the passivation performance of hexavalent chromium.
The scientific principle of the invention is as follows:
the isopropyl tri (dioctyl pyrophosphoric acid acyloxy) titanate can enable inorganic addition nano particles and the like in the passivation film to be firmly adsorbed on the surface of the galvanized layer, ensure the toughness of the coating and avoid the cracking or falling of the coating due to deformation or other stress. The adsorbed inorganic particles have pinning effect on the resin film layer at the same time, so that the adhesive force of the organic coating is improved. Vanadyl oxalate provides tetravalent vanadium, the aqueous solution of tetravalent vanadium has higher stability, tetravalent vanadium has simpler hydrolytic balance in liquid phase compared with pentavalent vanadium, and stable solution of tetravalent vanadium can be obtained. And the tetravalent vanadium can realize self-repairing capability in the use process of the coating. The polyethylene wax is added, a layer of polyethylene wax is formed on the surface of the passivation film layer in the curing process, and the surface of the galvanized layer has scratch resistance and low friction coefficient due to the high hardness and high lubricity of the polyethylene wax, so that the phenomenon of friction blackening generated in the collision and friction processes of galvanized steel parts can be reduced.
