摘　　要：研究了乙炔炭黑和超导炭黑填充天然橡胶（ＮＲ）、丁腈橡胶（ＮＢＲ）和三元乙丙橡胶（ＥＰＤＭ）胶料的基本电性能和物理机械性能。实验结果表明，胶料电阻率在老化后均有不同程度的下降：测试环境温度发生变化时，胶料电阻率随着热能的吸收呈下降趋势。The electric and physical properties of NR,NBR or EPDM compounds filled with acetylene black and super conductive black were studied. The test results showed that the electrical resistivity of the compounds decreased to different degrees after aging; the electrical resistivity decreased with the absorption of heat energy when the temperature of the test atmosphere changed.
