摘　　要：对乙炔炭黑填充硅橡胶的导电性能进行研究。实验结果表明:在甲基乙烯基硅橡胶中,随着乙炔炭黑用量增加,试样的体积电阻率呈降低趋势;白炭黑对硅橡胶导电性能有较大不良影响;经过热处理后,硅橡胶的导电性能有明显改善。　The electrically conductive properties of silicone rubber filled with acetylene black were studied.The results showed that the volume resistivity of the silicone rubber reduced while the acetylene black increased or the silica reduced,and the volume resistivity of the silicone rubber also reduced after heat treatment in air.
