Problems solved by technology

Heating phosphating, the quality of the phosphating film is better, but it needs to be heated, which consumes a lot of energy, and the process and equipment are more complicated
Although phosphating at room temperature does not require heating and consumes less energy, but the phosphating time is longer, the adhesion is not strong, and the phosphating film is easy to peel off
Phosphating solution generally contains water and needs to be replaced after a period of use

Abstract

There is a kind of quick non-water bonderizing liquid, it belongs to chemistry treatment field of metal surface. The techonlogy is providing a kind of quick, normal temperature and short time bonderizing liquid. The technology scheme is, the proportion is: 5-15 poly vinyl alcohol butyric aldehyde, 60-100 alcohol, 4-10 orthophosphoric acid, 0.1-1 tannin, 12-30 pimelin ketone, 10-20 resin. The manufacturing method is: poly vinyl alcohol butyric aldehyde is added into alcohol and immersed for 24 hours, then adds in resin and pimeline ketone, heated and blended; the tannin is added into orthophosphoric acid and immersed for one hours, and adds in pimelin ketone and blended, then blended the two mixed liquid and gets the bonderizing liquid.

Description

Technical field: [0001] The invention belongs to the technical field of surface chemical treatment of metal materials whose surface reacts with a reaction liquid. Background technique: [0002] Phosphating of steel components before coating, there are two methods of heating phosphating and room temperature phosphating. Heating phosphating, the quality of the phosphating film is better, but heating is required, energy consumption is large, and the process and equipment are more complicated. Although phosphating at room temperature does not require heating and consumes little energy, the phosphating time is longer, the adhesion is not strong, and the phosphating film is easy to peel off. Phosphating solution generally contains water and needs to be replaced after a period of use. Summary of the invention: [0003] The technical problem to be solved by the present invention is to provide a phosphating solution that can be used at room temperature, has short phosphating time, strong...
