【Abstract】 A new type of metal surface protection silane coupling agents-vinyltrichlorosilane was selected,and was hydrolyzed in water and alcohol mixed solution.The hydrolysis stability of the metal surface protection agent was good,and the silicon hydroxyl content could be guaranteed to remain.Through water resistance test,saline soaking test,acid and alkaline-proof test and 3% CuSO4 solution pitting corrosion test,the results showed that the performances such as water resistance,salt water resistance,acid and alkaline proof resistance and CuSO4 solution corrosion resistance of the new type of metal surface protection silane coupling agents were good,and it had great advantages such as no pollution and low cost.The metal surface had better corrosion resistance after treatment with using this silane coupling agent than with using traditional phosphating technology.更多还原
