Abstract:
The present invention provides a passivant for hot-dip Al—Zn-coated sheet of which the raw materials include: 2˜6 parts by weight of water soluble molybdate, 4˜12 parts by weight of water soluble manganese salt, 50˜100 parts by weight of basic silica sol and 50˜100 parts by weight of water soluble organic resin. The present invention also provides a method to prepare the passivant for hot-dip Al—Zn-coated sheet including the following steps: adding and dissolving water soluble molybdate and water soluble manganese salt into deionized water; adding basic silica sol into the solution and mixing well; adding water soluble organic resin into the solution and mixing well; regulating the pH value of the solution to 5˜8 by using phosphoric acid. The present invention also provides a hot-dip Al—Zn-coated sheet treated with the present passivant and a method to passivate hot-dip Al—Zn-coated sheet.
