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２，５－二甲基－２，５－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。
Nitrile butadiene rubber (NBR)/polyoxymethylene (POM) thermoplasticelastomers were prepared by dynamic vulcanization with peroxide. The effects 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-dimethyl -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,electric insulation,aging resistance and oil resistance improved significantly.
