Abstract

The invention discloses a passivator for metal plates. The passivator for metal plates is prepared from, by weight, 1-2 parts of phosphoric acid, 7.8 parts of phosphoric acid, 0.7 part of residue extract of rhizomes of shouliang yam, 1.1 parts of sodium dodecyl sulfate, 2.3 parts of vinyl trimethoxy silane, 0.9 part of dodecyltrimethylammonium bromide, 8.4 parts of etidronic acid, 1.2 parts of sodium alkyl succinic ester sulfonate, 0.7 part of sodium aluminate and 36 parts of deionized water. The passivator for metal plates can be used for passivating treatment of metal, a uniform passivating protection film can be formed on the surface of metal, and the protection film has excellent rust-proof performance, abrasion resistance, corrosion resistance, heat resistance, cold resistance and weather resistance and is good in surface smoothness.

Description

technical field [0001] The present invention relates to a metal plate passivator. Background technique [0002] Existing passivating agents for metal plates are used for passivation treatment of metals to form a passivation protective film on the metal surface, but the antirust, abrasion resistance, corrosion resistance, heat resistance, cold resistance and weather resistance of the protective film need to be improved. And the surface finish is not ideal enough. Contents of the invention [0003] The purpose of the present invention is to provide a passivating agent for metal plates, which can be used for the passivation treatment of metals and form a uniform passivation protective film on the metal surface. The protective film has excellent rust resistance, abrasion resistance, corrosion resistance and heat resistance. , cold resistance, weather resistance, and good surface finish. [0004] In order to achieve the above object, the technical scheme of the present invent...
