镀镍石墨／三元乙丙橡胶导电复合材料的性能研究

研究镀镍石墨（NCG）用量对NCG/三元乙丙橡胶（EPDM）导电复合材料性能的影响，遴选出最佳硅烷偶联剂，研究其用量对复合材料导电稳定性的影响.结果表明，随着NCG用量的增大，复合材料的体积电阻率逐渐降低，当NCG用量超过240份时，复合材料的体积电阻率降至10 Ω·cm以下、Al37是一种有效的硅烷偶联剂，当其用量为9份时，复合材料的各项性能较好。;The influence of the content of nickel coated graphite（NCG）on the properties of NCG/EPDM electrically conductive composite was studied.the effective silane coupling agent was selected.and the effect of its content on the electrically conductive stability of the composite was investigated. The results showed that with the increase of addition level of NCG.the volume resistivity of the composite decreased.When the addition level of NCG was more than 240 phr，the volume resistivity could be reduced to 10 Ω·cm.It was found that A137 was an effective silane coupling agent and the properties of the composite were better when the addition level of A137 was 9 phr
