摘要

通过对硅橡胶材料的表面腐蚀、化学腐蚀以及老化引起污秽层形成这3种老化途径的机理分析

表明硅橡胶具有极好的抗老化性。同时

指出漏流径形成是造成硅橡胶老化的最主要原因。盐雾试验证明

老化引起绝缘性能降低后

经过一段时间

硅橡胶表现出本身具有自恢复性。

Abstract

Through analyzing the three ageing mechanisms of the silicone rubber material

i.e.

the surface corrosion

the chemical corrosion and the forming of dirty layer by ageing

it is demonstrated that the silicone rubber has a better age-inhibiting function.Moreover

the major reason leading to ageing of silicone rubber is the forming of leakage-current pathway.Salt-fog test shows that the silicone rubber has a function of self-restoration after the insulation level is lowered due to ageing for a period of time.
