Abstract

The invention discloses a stainless steel passivating agent which consists of the following components in parts by weight: 1-2 parts of borax anhydrous, 0.9 part of potassium chlorate, 0.7 part of silicon-calcium powder, 4.9 parts of tannic acid, 1.8 parts of hydroxyl propyl methylcellulose, 2.3 parts of fatty amine polyoxyethylene ether, 1.1 parts of ammonium hexafluorotitanate, 1.3 parts of alkyl sodium sulfovinate, 0.7 part of titanyl sulfate and 44 parts of deionized water. The stainless steel passivating agent disclosed by the invention can be used for passivating treatment of metal, so that a uniform passivating protective film is formed on the surface of the metal; and the protective film has excellent rust protection, abrasion resistance, corrosion resistance, heat resistance, cold resistance, weather resistance, and is good in surface smoothness.

Description

technical field [0001] The invention relates to a passivator for stainless steel. Background technique [0002] Existing stainless steel 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 purpose of the present invention is to provide a kind of stainless steel passivation agent, can be used for the passivation treatment of metal, forms uniform passivation protection film on the 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 sta...
