摘　　要：研究了氨基硅烷偶联剂对提高环氧涂层与钢铁基底材料的附着力的作用。主要对其水解特性和对涂层附着力的影响进行了测试，并利用反射红外（RAIR）对氨基硅烷偶联剂的作用机理进行了分析。结果表明，氨基硅烷偶联剂在极少量水分的条件下就能够水解形成硅羟基，添加氨基硅烷偶联剂的涂层与底材之间有化学键作用，能够显著提高涂层与底材的附着力，与纯环氧涂层相比，可以提高5～6MPa。Amido-silane coupling agent was used to increase the adhesion of the epoxy resin coating on iron and steel substrates. Thus the hydrolysis behavior of the amido-silane coupling agent and its effect on the adhesion of the epoxy coating on iron-steel substrate were investigated, while the action mechanisms of the coupling agent was examined by means of reflective infrared spectrometry. It was found that the amido - silane coupling agent had very strong hydrolysis ability and was able to greatly increase the adhesion of the epoxy resin coating by forming chemical bond between the coating and the substrate. Namely, the adhesion of the coating with the coupling agent was 5- 6 MPa higher than that of the epoxy resin coating without the coupling agent.
