摘要
对比研究星形接枝溴化丁基橡胶(BIIR6222)与通用溴化丁基橡胶(BIIR2222)在轮胎气密层中的应用性能。结果表明:与BIIR2222相比,BIIR6222具有焦烧时间长、加工能耗低、压延尺寸收缩率小等优点,物理性能相当,气密性略优。
The application of star grafted brominated butyl rubber(BIIR6222)and general brominated butyl rubber(BIIR2222)in the inner liner of tire was compared and investigated.The results showed that,compared with BIIR2222,BIIR6222 had the advantages oflong scorching time,low energy consumption in the processing and low shrinkage during calendering.Its physical properties were similar to that of BIIR2222,and air tightness was better.
