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 phosphating agents on the market now, after the workpiece is phosphating, the film layer is too thick, the hardness is not strong, and the wear resistance is not high.
Can not meet the requirements of workpiece wear resistance

Abstract

The invention discloses a high-wear-resistance phosphating solution and a preparation method thereof. The high-wear-resistance phosphating solution is prepared from, by weight, 10-15 parts of polyvinylpyrrolidone, 3-8 parts of hexamine, 15-20 parts of lauryl sodium sulfate, 1-3 parts of ammonium peroxydisulfate, 3-6 parts of stearic acid triethanolamine ester quaternary, 2-6 parts of sodium xylene sulfonate, 2-6 parts of sodium fluosilicate, 10-20 parts of hydroxylamine sulphate, 3-6 parts of sodium metanitrobenzene sulfonate, 55-65 parts of deionized water and 5-8 parts of isooctyl palmitate. Compared with an existing phosphating solution and phosphating technology, the high-wear-resistance phosphating solution is adopted for carrying out phosphating treatment on a workpiece, and therefore the phosphating technology is simplified, phosphating efficiency is improved, and phosphating cost is reduced. Meanwhile, a phosphating film formed by the high-wear-resistance phosphating solution is more compact, evener, excellent in bonding force with a workpiece substrate and excellent in wear resisting property, and the preparation method is simple and low in cost.

Description

technical field [0001] The invention relates to a highly wear-resistant 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 chemical and electro...
