| 中文摘要: |
| 以预分散多壁碳纳米管（MWCNTs）为导电填料，研究预分散MWCNTs/三元乙丙橡胶（EPDM）复合材料的硫化特性、物理性能和导电性能。结果表明：与MWCNTs/EPDM复合材料相比，预分散MWCNTs/EPDM复合材料的t90大幅缩短，门尼粘度减小，硫化效率和加工性能提高；预分散MWCNTs/EPDM复合材料的拉伸强度、拉断伸长率、撕裂强度和压缩永久变形增大，100%定伸应力和回弹值减小，预分散MWCNTs/EPDM复合材料有更明显的导电逾渗现象，导电性能提高。 |

| The vulcanization characteristics，physical properties and conductivity performance of the pre-dispersion multi-walled carbon nanotubes（MWCNTs）/ethylene-propylene-diene rubber（EPDM）composites were studied by using the conductive filler of the pre-dispersion MWCNTs.The results showed that compared with the MWCNTs/EPDM composite，thet90 of the pre-dispersed MWCNTs/EPDM composite was significantly shorted，and the Mooney viscosity decreased，vulcanization efficiency and the well of processing properties increased.The tensile strength，elongation at break，tear strength and compressive set of the pre-dispersed MWCNTs/EPDM composite increased，and the stress at 100% elongation and rebound value decreased.The pre-dispersed MWCNTs/EPDM composite had more obvious conductive percolation phenomenon，and its conductive performance was improved. |
