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 rust-removing and phosphating agents currently on the market are mainly used to clean and remove rust with hydrochloric acid, nitric acid, and sulfuric acid according to different metals, generating toxic and choking yellow and red smoke, resulting in serious corrosive three-waste pollution, and easy to clean. The metal itself of the parts: the outer layer dissolves to form over-corrosion, and the inner hydrogen permeates to cause hydrogen embrittlement, which endangers the safety of use and shortens the service life

Abstract

The invention discloses an anti-rust phosphating solution and a preparation method thereof. The anti-rust phosphating solution is prepared from the following raw materials in parts by weight: 10-16 parts of polyvinylpyrrolidone, 3-6 parts of sodium 3-nitrobenzene sulfonate, 5-9 parts of stearic acid triethanolamine ester quaternary ammonium salt, 5-9 parts of marigold essential oil, 3-7 parts of ethylenediaminetetraacetic acid, 5-7 parts of allyl glycidyl ether, 3-5 parts of tartaric acid, 15-20 parts of 2-methyl-4-isothiazolin-3-one, 4-5 parts of hexamethylenetetramine, 6-8 parts of sodium lauryl sulfate, 100-110 parts of water and 12-16 parts of zinc dihydrogen phosphate. Compared with a conventional phosphating solution and a conventional phosphating process, the anti-rust phosphating solution and the preparation method disclosed by the invention have the advantages that when the anti-rust phosphating solution is adopted for phosphating treatment of a workpiece, the phosphating process is simplified, the phosphating efficiency is improved and the phosphating cost is reduced; meanwhile, a phosphating film formed by adopting the anti-rust phosphating solution not only is denser and more uniform, but also can be effectively protected from rust; and the preparation method is simple and low in cost.

Description

technical field [0001] The invention relates to an antirust 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 electrochemical rea...
