Problems solved by technology

Although scientists have done a lot of research in this area, it is not yet fully understood
After the end of World War II, there were few breakthroughs in phosphating technology, but steady development and improvement.
However, the degreasing and phosphating agents currently on the market use strong alkaline hot solutions (high energy consumption, heavy pollution, and the floating oil on the surface of the working fluid will cause secondary oil pollution to the treated parts), or use strong acids, or use easy Combustible, explosive, and toxic organic solvents produce toxic, highly corrosive, and heavy pollution of gas, liquid, and solid wastes, and also do not meet the needs of clean production development in the existing society

Abstract

The invention discloses an environment-friendly oil removal phosphating solution and a preparation method thereof. The environment-friendly oil removal phosphating solution is prepared from, by weight, 10-20 parts of methyl acrylate, 2-6 parts of hexamine, 6-9 parts of hydroxylamine sulphate, 2-6 parts of polyvinylpyrrolidone, 4-5 parts of ammonium peroxydisulfate, 2-6 parts of starch ether, 12-16 parts of zinc nitrate, 2-6 parts of polyethylene benzyl trimethyl quaternary ammonium salt, 2-6 parts of stearic acid triethanolamine ester quaternary, 100-120 parts of water, and 7-9 parts of sodium fluosilicate. A phosphating film prepared through the environment-friendly oil removal phosphating solution is compact and uniform; the oil removal procedure in the phosphating process is simplified, and the phosphating efficiency is improved; and the preparation method is simple and low in cost.

Description

technical field [0001] The invention relates to an environment-friendly degreasing and phosphating solution and a preparation method thereof. Background technique [0002] Phosphating is a commonly used pretreatment technology. In principle, it should belong to chemical conversion film treatment. It is mainly used for phosphating on the surface of steel, and non-ferrous metals (such as aluminum and zinc) can also be phosphating. Phosphating is a process in which chemical and electrochemical reactions form a phosphate chemical conversion film, and the formed phosphate conversion film is called a phosphating film. The purpose of phosphating is mainly to provide protection for the base metal and prevent the metal from being corroded to a certain extent; it is used as a primer before painting to improve the adhesion and anti-corrosion ability of the paint film layer; it can reduce friction in the metal cold processing process Lubrication. The phosphating process includes chemi...
