摘　　要：采用双(3-三乙氧基甲硅烷基丙基)胺和乙烯基三乙酰氧基硅烷的混合体系,对冷轧钢表面进行硅烷化处理,通过监测硅烷水解液在不同水解时间的pH值和电导率,研究其稳定性能,并研究了硅烷含量和水解溶剂中乙醇的含量对所制备硅烷膜耐腐蚀性能的影响。结果表明:混合硅烷体系的水解液具有较好的稳定性;当混合硅烷含量为2%,水解溶剂中乙醇含量为20%时,所制备硅烷膜具有较好的耐腐蚀性能,且满足工业应用要求。The silane surface treatment based on the mixture of bis（triethoxysilylpropyl）amine and vinyltriacetox-ysilane had been developed for cold rolled steel. The pH value and conductivity were monitored to investigate solution stability. The effect of silane solution concentration and the content of ethanol in solvent on the anti corrosion perform-ance were also studied. The results indicate that the solution stability is good. When the concentration of silane solution is 2% and the content of ethanol in solvent is 20%, the silane film prepared shows good anti-corrosion performance, which meets the requirement of industrial application.
