| 中文摘要: |
| 研究了三水合氧化铝、增塑剂及偶联剂用量对三元乙丙橡胶电性能的影响。结果表明，三水合氧化铝能有效提高三元乙丙橡胶的抗漏电起痕性能及抗腐蚀性能，但同时引起介电常数及损耗因子增大，电阻率下降；增塑剂及偶联剂用量增加均使电性能降低，其用量应限定在一定范围内。 |
| 英文摘要: |
| The influence of the level of alumina trihydrate，plasticizer and coupling agent on the electrical property of EPDM was studied.The result showed that using alumina trihydrate，the electrical tracking resistance and electric erosion resistance of EPDM could be improved but the dielectric coefficient and loss factor would increase and the electrical resistivity would decrease；the electrical property would decrease as the level of plasticizer and coupling agent increase，so their loading level had to be in a certain range. |
