Abstract

The invention provides a preparation method of an anticorrosion passivation solution, which comprises uniformly mixing water, a silane coupling agent, a water-soluble silicate, a silicon oxide filler and a water-soluble film-forming resin in sequence. The present invention also provides the anti-corrosion passivation solution prepared according to the above-mentioned preparation method and the application of the above-mentioned anti-corrosion passivation solution in the preparation of metal materials. The present invention also provides a hot-dip metal material, which includes a hot-dip metal substrate and a coating attached to the hot-dip metal substrate, the coating is the above-mentioned anti-corrosion passivation liquid solidified product. The protective film formed by the anti-corrosion passivation solution provided by the invention has excellent corrosion resistance. In addition, the anti-corrosion passivation solution provided by the invention has excellent storage resistance, and can be stored at room temperature for 180 days after preparation without obvious change in properties and performance decline.

Description

technical field [0001] The invention relates to the field of metal protection, in particular to a preparation method of an anti-corrosion passivation solution, an anti-corrosion passivation solution obtained by the preparation method, uses of the anti-corrosion passivation solution and a hot-dip metal material. Background technique [0002] Hot-dip metal materials, including hot-dip galvanized metal materials and hot-dip galvanized metal materials, in order to prevent corrosion, a layer of anti-corrosion passivation solution will be coated on the surface of the hot-dip metal materials to form a protective film. Therefore, the performance of the anti-corrosion passivation solution is very important for the anti-corrosion of hot-dip metal materials. [0003] For example, CN101608306A discloses a passivation solution, which also belongs to an anti-corrosion passivation solution, and is characterized in that the passivation solution is an aqueous solution containing water-solubl...
