| 摘 要： | 用马来酸酐接枝聚丙烯（ＭＰ）／胺／端羧基液体工腈橡胶（ＣＴＢＮ）反应，生成ＰＰ－ＮＢＲ嵌段共聚物作为相容剂制备ＮＢＲ／ＰＰ动态硫化共混型热塑性弹性体效果很好，其中尤以ＭＰ／１．６－己二胺／ＣＴＢＮ效果最为理想。相容剂用量控制在６％左右。ＰＰ的熔融指数越小，共混体的性能越好。硫化体系采用酚酸树脂２４０２／氯化亚锡（８／０．５）、加入一定量的增塑剂邻苯二甲酸二辛酯和补强剂高耐磨炭黑，可获得性能较好的共混体。

| Abstract: | A dynamically-curable thermoplastic elastomer of NBR/PP blend was prepared with a block copolyrner formed in the reaction of maleic anhydride-graft polypropylene (MP)/a amine / liquid carboxyl terminal butadiene nitrile rubber (CTBN) as compatibilizer. Among ammes, hexamethylene-diamine was the most efficient. The preferrable level of the compatibilizer was about 6%. The lower the melt index, the better the properties of the blend. A blend with better properties could be obtained by adding phenolic resin 2402/tin bichloride (8/0. 5) curative and a certain level of dioctyl phthalate plasticizer and HAF reinforcing agent. |
