| 摘 要： | 采用异丙基黄原酸钠SIP、N-乙基-N-苯基二硫代氨基甲酸PX的复合促进剂体系(用量分别为1.5phhr和0.5phhr)可使天然橡胶/顺丁橡胶并用胶(并用比为70∶30)在90℃~95℃内快速硫化,硫化特性符合缓冲胶工艺的要求,但其性能与HG/T 4124-2009《预硫化缓冲胶》存在一定的差距。

| Abstract: | Isopropyl xanthate sodium （ SIP） and N-Ethyl-N-phenyldithiocarbamic Acid Zinc Salt （ PX） ,1.5 and 0.5phhr respectively ,are applied to make up complex accelerator system ,and cause the NR/BR blends （ with a blending ratio of 70∶30 ） fast curing at 90℃~95℃.The vulcanization characteristics meet requirements of the cushion gum processing , but its performances keep a certain distance from those described in the HG /T 4124 -2009“precured tread cushion gum”. |
