摘要
通过动态硫化工艺制备了溴化丁基橡胶(BIIR)/聚丙烯(PP)热塑性弹性体,研究了加工时间、填料、硫化剂对弹性体力学性能的影响。结果表明,动态硫化制备热塑性弹性体的时间约为13 min;使用炭黑N330/白炭黑双相填料的热塑性弹性体具有较好的力学性能;在氧化锌、硫磺、溴化辛基酚醛树脂及硫磺/溴化辛基酚醛树脂并用硫化体系中,溴化辛基酚醛树脂硫化的热塑性弹性体力学性能最佳。
Brominated butyl rubber（BIIR） / polypropylene（PP） thermoplastic elastomer（TPE） was prepared by dynamic vulcanization technology.The effects of time,fillers and curing agents on mechanical properties of BIIR/PP TPE were studied.The results showed that the time preparing TPE was about 13 min;BIIR/PP TPE packed by N330/WCB diphase fillers had good mechanical properties;among ZnO,sulfur,bromo-octyl-phenolic resin and sulfur/ bromo-octyl-phenolic resin curing systems,comprehensive properties of TPE dynamically vulcanized by bromo-octyl-phenolic resin were best.
