Problems solved by technology

[0002] In the field of metal surface treatment, although the traditional phosphate conversion and chromate passivation surface treatment technologies can achieve good results, the above two treatment methods have major defects: poor environmental compatibility and high cost of use
[0004] However, the silane treatment agents in the prior art do not have the characteristics of concentration, which leads to their large volume and inconvenient transportation and storage.

Abstract

The invention discloses a silane treating agent for metal surfaces. The silane treating agent is composed of, by weight, 20-30 parts of silane coupling agents, 20-30 parts of film-forming agents, 5-7 parts of complexing agents and 15-30 parts of purified water. According to the silane treating agent, the film-forming agents are thickening agents, and the complexing agents are sodium citrate, so that the silane treating agent has superior environment-friendly properties such as high ageing, hyper concentration, low carbon, energy conservation and no residue, phosphorus, zinc, chromium, fluorine or zirconium; a silane film has good effects of corrosion resistance property and adhesion property.

Description

technical field [0001] The present invention relates to a silane treatment agent, more specifically, it relates to a metal surface silane treatment agent. Background technique [0002] In the field of metal surface treatment, although the traditional phosphate conversion and chromate passivation surface treatment technologies can achieve good results, the above two treatment methods have major defects: poor environmental compatibility and high cost of use. Environmental hazards: phosphating contains zinc, manganese, nickel and other heavy metal ions and a large amount of phosphorus, and nitrite is used as an accelerator in the production and use process, which is a serious carcinogen. Chromium treatment itself contains seriously toxic chromium (Ⅵ). Due to the promulgation of regulations on the danger of heavy metals, chromium (Ⅵ)-containing treatment methods will be banned in many fields (the European Union has completely banned chromium in July 2007. (Ⅵ) Use in metal surfa...
