摘　　要：硅橡胶以其独特的化学键和结构所带来的的特性在电力行业中得到了广泛的应用,但其在实际运行中不可避免的会出现老化现象。通过制备一系列固体硅橡胶样片,定期跟踪检测其机械性能和电气性能的变化,并通过傅里叶红外光谱分析仪(FT-IR)和扫描电子显微镜(SEM)分析固体硅橡胶老化前后微观官能团变化和宏观表面结构变化。结果表明:实验所用的固体硅橡胶具有较好的机械性能和电气性能。Silicone rubber has been widely used in power industry because of its unique chemical bond and structure during natural aging,but it will inevitably appear aging phenomenon in the actual operation.A series solid silicone rubber samples were prepared,and detected regularly the change of mechanical and electrical properties.The changes of micro functional groups and macro surface structure of the rubber before and after aging were analyzed by FTIR and SEM.The results shown that the rubber used in the experiment had good mechanical and electrical properties.
