Design and Performance Study of High Conductive Silicone Rubber for Aviation
摘要:
本文通过高导电硅橡胶配方中硅橡胶和导电填料的选型和测试的实验，对硫化合成后的玻璃镀银微珠导电橡胶和铝镀银导电橡胶进行一系列环境试验前后指标的对比研究，研究结果表明采用30度级且平均分子量120万的乙烯基硅橡胶和平均粒径40 µm的铝镀银或玻璃镀银填料制成的高导电硅橡胶具有优秀的电性能、力学性能和环境适应性能。
Abstract:
In this paper, through the selection and testing of silicone rubber and conductive filler in high conductive silicone rubber formulation, a comparative study of indexes before and after a series of environmental tests was conducted on the glass coated silver coated micro conductive rubber and aluminum silver plated conductive rubber. The results show that high conductive silicone rubber, made of the vinyl silicone rubber of 30 degree and the average molecular weight of 1 million 200 thousand and the aluminum silver or silver plated glass filler of the average particle size of 40 µm, has excellent electrical properties, mechanical properties and environment properties.
