动力转向管用氯磺化聚乙烯
摘要：
本发明涉及动力转向管用氯磺化聚乙烯无铅配方。配方组分为：氯磺化聚乙烯橡胶(CSM)：100份，快压出炉黑(N550)：30～50份，软化剂T810T：15～35份，癸二酸二辛酯(DOS)：5～20份，轻质碳酸钙：10～20份，流动助剂WS1 80：0.5～2份，流动助剂WA 48：0.5～2份，防老剂NDBC：0.5～2份，N’N-间苯撑双马来酰亚胺(HVA-2)：0.5～3份，四硫化双五甲撑秋兰姆(DPTT)：0.5～2份，二硫化二苯并噻唑DM：0.5～1份。本发的明配方具有高强度、高硬度、低压缩残余变型、耐油等特性，完全达到动力转向管的要求，同时无毒、无味，贮藏稳定。
摘要（英）：

The invention relates to a chlorosulfonated polyethylene lead-free recipe for a power steering pipe. The recipe contains the following components: 100 parts of chlorosulfonated polyethylene rubber (CSM), 30-50 parts of fast extruding furnace black (N550), 15-35 parts of softener T810T, 5-20 parts of dioctyl sebacate (DOS), 10-20 parts of light calcium carbonate, 0.5-2 parts of flow promotor WS1 80, 0.5-2 parts of flow promotor WA 48, 0.5-2 parts of antiager NDBC, 0.5-3 parts of N'N-m-phenylene dimaleimide (HVA-2), 0.5-2 parts of dipentamethylenethiuram tetrasulfide (DPTT) and 0.5-1 part of dibenzothiazyl disulfide DM. The recipe has the characteristics of high strength, high hardness, low compression residual deformation, oil resistance and the like, thereby completely meeting the demands of the power steering pipes; meanwhile, the recipe has no toxin or odor and is stable in storage.
