Abstract

The invention provides a normal-temperature phosphating solution and a method for preparing the same. The normal-temperature phosphating solution is mainly made from materials of hydroxylamine sulphate, phosphoric acid, sodium dihydrogen phosphate, fatty alcohol polyoxyethylene ether, cerous nitrate, zinc oxide, manganese phosphate and water. The preparation technology is simple and practicable, and the operation is convenient. The normal-temperature phosphating solution has competences of rust and oil fouling removing, and economizes the whole phosphating process by being combined with a sand blasting process; phosphating film after phosphating process has good anti-crazing, deformation resistant and shock resistant competences and a good combining capacity with an organic coating, and the phosphating film is a good base layer for the coating; and the normal temperature during a phosphating process is operable, the phosphating time is short, and the effect is good.

Description

Technical field

[0001] The invention relates to a normal temperature phosphating solution and a preparation method thereof. Background technique

[0002] Phosphating is to treat steel workpieces in a solution containing phosphate, oxidation promoters, and additives to form a phosphating film on the surface. The phosphating film has the functions of anti-corrosion, abrasion resistance, improving coating adhesion, lubrication and the like. Phosphating treatment is performed on the surface of steel. The traditionally used phosphating solution has high temperature, high energy consumption, long time and high cost. Especially for large workpieces such as automobile chassis and parts, it is more difficult for some small and medium-sized enterprises to carry out medium and high temperature phosphating. With the progress of phosphating technology, modern phosphating treatment is mainly developing towards low temperature, rapid formation of thin and good protective phosphate film. [000...
