| 中文摘要: |
| 采用过氧化物硫化体系用动态硫化方法制备了丁腈橡胶/聚甲醛（NBR/POM）热塑性弹性体。研究了硫化体系、橡塑比对共混物性能的影响。实验结果表明采用2，5一二甲基一2，5一双（叔丁基过氧基）己烷硫化体系硫化效果较好，共混物的综合性能优异；随着POM用量增加，共混物的拉伸强度略有增加，表观粘度降低，加工性能变好，电绝缘性能、老化性能和耐油性能均得到明显改善。 |
| 英文摘要: |
| Nitrile butadiene rubber(NBR)/polyoxymethylene(POM) thermoplastic elastomers were prepared by dynamic vuleanization with peroxide.The effeets of the curing system and the amount of POM on properties of NBR/POM blends were studied.The test results showed that the NBR/POM blend exhibited excellent comprehensive Properties when cured with 2，5-dirnethyl-2，5-di(t-butylperoxy) hexane；with the increase of the amount of POM in the blend，the tensile strength increased， the apparent viscosity decreased，the processibility，eleetric insuation，aging resistance and oi1 resistance improved significantly.
