| titleOfInvention | High-corrosion-resistance galvanized steel sheet and preparation method thereof |
| abstract | The invention discloses a high-corrosion-resistance galvanized steel sheet and a preparation method thereof. The high corrosion-resistant galvanized steel sheet comprises a cold-rolled steel sheet, a zinc coating on the surface of the cold-rolled steel sheet and a protective film on the surface of the zinc coating, wherein the protective film is formed by solidifying a passivation solution, and the passivation solution comprises a component A and a component B in a mass ratio of 1: 1.2-1.8; the preparation method comprises the following steps: s1, sequentially carrying out alkali washing and water washing on the cold-rolled steel plate; s2, annealing the cleaned cold-rolled steel sheet; s3, hot galvanizing the annealed steel plate to form a galvanized layer; s4, putting the galvanized steel plate into the passivation solution, soaking for 10-15min, taking out, standing for 20-25h, curing to form a protective film, uniformly coating the protective film with the protective solution, and standing for 1-2h to form the high-corrosion-resistance galvanized steel plate. The high corrosion resistance galvanized steel sheet has the advantages of chromium-free passivation and good corrosion resistance. |
