| 中文摘要: |
| 用马来酸酐接枝聚丙烯（MP）/胺/端羧基液体丁腈橡胶（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。硫化体系采用盼醒树脂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。 |
| 英文摘要: |
| A dynamically-curable thermoplastic elastomer of NBR/PP blend was prepared with a block copolymer formed in the reaction of maleic anhydride-graft polypropylene (MP)/a amine/liquid carboxyl terminal butadiene nitrile rubber (CTBN) as compatibilizer.Among amines, 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. |
