摘　　要：采用一步法对钢铁表面化学吸附成膜技术进行了研究,通过单因素试验优化出较佳的工艺条件:聚乙二醇(400)20mL/L,三乙醇胺40mL/L,硅烷偶联剂10mL/L,丙三醇15mL/L,温度45°C,pH=10,处理时间8min。试验结果表明,在此条件下得到的化学吸附膜耐硫酸铜点滴时间为68s,附着力0级,冲击强度50kg·cm。该化学吸附膜综合性能优于传统的磷化膜。The chemical adsorption film forming process on surface of iron and steel was studied by one-step method. The process conditions were optimized by single factor test as follows： polyethylene glycol （400） 20 mL/L, triethanolamine 40 mL/L, silane coupling agent 10 mL/L, glycerin 15 mL/L, temperature 45 ℃, pH 10, and treatment time 8 min. The test results showed that the chemical adsorption film prepared under the optimal conditions endures CuSO4 dropping corrosion test for 68 s, and has a 0-grade adhesion strength and a impact strength of 50 kg.cm. The comprehensive performance of the chemical adsorption film is better than that of traditional phosphating film.
