Abstract

The invention discloses an aluminum passivation agent. The aluminum passivation agent is composed of, by weight, 1-2 parts of calcium chloride, 8.5 parts of malonic acid, 6.5 parts of organic phosphonic acid, 1.8 parts of 2-phosphonobutane-1,2,4-tricarboxylic acid, 2.3 parts of hydroxypropyl cellulose, 2.1 parts of polyoxyethylene castor oil, 0.7 part of beta-naphthylamine, 1.5 parts of isodecanol polyoxyethylene ether, 1.1 parts of titanium (IV) acetylacetonate and 40 parts of deionized water. The aluminum passivation agent can be used for passivation treatment of metal, a uniform passivation protective film is formed on the surface of the metal, and the protective film has excellent antirust performance, friction resistance, corrosion resistance, heat resistance, cold resistance and weather resistance and is good in surface degree of finish.

Description

technical field [0001] The present invention relates to an aluminum passivator. Background technique [0002] Existing aluminum passivators 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 also less than ideal. Contents of the invention [0003] The object of the present invention is to provide a kind of aluminum passivation agent, can be used for the passivation treatment of metal, forms uniform passivation protection film on metal surface, and protection film has excellent antirust, abrasion resistance, corrosion resistance, heat resistance, Cold resistance, weather resistance, and good surface finish. [0004] For achieving the above object, technical scheme of the present invention is to design a kind of aluminum passivator, is ...
