| 中文摘要: |
| 探讨氯磺化聚乙烯橡胶（CSM）、氯化聚乙烯橡胶和乙烯-乙酸乙烯酯共聚物作为相容剂对丁腈橡胶（NBR）/三
元乙丙橡胶（EPDM）并用胶的相容改性作用，并研究硫化体系对NBR/EPDM/CSM并用胶性能的影响。结果表明：CSM
作为相容剂能改善NBR与EPDM的相容性，提高NBR/EPDM并用胶的物理性能；随着促进剂DPTT用量的增大，NBR/
EPDM/CSM并用胶的物理性能提高；硫黄硫化体系与过氧化物硫化体系并用的NBR/EPDM/CSM并用胶的物理性能最
佳；过氧化物硫化体系单用的NBR/EPDM/CSM并用胶的耐热老化性能最佳。 |
| 英文摘要: |
| In this study，chlorosulfonated polyethylene rubber（CSM），chlorinated polyethylene rubber，
and ethylene-vinyl acetate copolymer were applied to improve the compatibility between nitrile rubber（NBR）
and ethylene-propylene-diene rubber（EPDM）. The modification effects were investigated and the effects
of curing systems on the properties of the NBR/EPDM/CSM blends were studied. The results showed that
the addition of CSM could improve the compatibility between NBR and EPDM and improve the physical
properties of the NBR/EPDM blends. With the increase of accelerator DPTT dosage，the physical properties
of NBR/EPDM/CSM blends were improved. The physical properties of the NBR/EPDM/CSM blends with
sulfur and peroxide combined curing system were the best，and the heat aging resistance of the NBR/EPDM/
CSM blends only with peroxide curing system was the best. |
