Problems solved by technology

However, the temperature of the phosphating solution needs to reach 45~65°C, and the energy consumption is high; a large amount of sediment is generated during the phosphating process, which not only wastes chemicals but also increases the workload of removing the waste residue. If it is not handled properly, it will also affect the quality of the phosphating film. ;The process is complex and the production continuity is poor
At the same time, a large amount of strong acid and strong alkali need to be used in the cleaning process, which increases the pollutant discharge load

Abstract

The invention discloses a metal surface treating agent. The metal surface treating agent comprises the following components: vinyl trimethoxy silane, laurinol, 2,2,4-Trimethyl-1,3-pentanediol monoisobutyrate, hydroquinone, ethanol, water, gamma-allyl glycidyl ether trimethoxy silane, benzotriazole, 4,4-methylene (2,6-di-tert-butylphenol), tallow amine, octyl amine, decyl alkyl amine, triethylamine, 8-hydroxyquinoline, hexyl amine, diamylamine, water-soluble chitin, nonox, didodecylamine, dioctadecylamine, triethanolamine, dodecylamine, hexadecylamine, octadecylamine, resorcinol, pyrocatechol, catechol, 2,6-di-tert-butyl-alpha-dimethylamino hydroquinone, fatty alcohol-polyoxyethylene ether, alkylphenol ethoxylates, polyoxyethylene stearates, and sodium bicarbonate. The metal surface treating agent obviously improves the adhesive force on the metal surface and realizes the corrosion resistance during coating of the whole metal.

Description

technical field [0001] The present invention relates to a metal surface treatment agent. Background technique [0002] At present, in the coating industry, the coating of metal products, especially plates, usually uses a phosphating process to improve the adhesion between the coating and the metal. However, the temperature of the phosphating solution needs to reach 45~65°C, and the energy consumption is high; a large amount of sediment is generated during the phosphating process, which not only wastes chemicals but also increases the workload of removing the waste residue. If it is not handled properly, it will also affect the quality of the phosphating film. ; The process is complex and the production continuity is poor. At the same time, a large amount of strong acid and strong alkali needs to be used in the cleaning process, which increases the pollutant discharge load. Contents of the invention [0003] The object of the present invention is to provide a metal surfac...
