中文摘要:
      研究星形支化溴化丁基橡胶(BIIR)6222在全钢载重子午线轮胎气密层中的应用,并与传统BIIR2222进行对比。结果表明:与BIIR2222胶料相比,BIIR6222胶料的加工性能较好,焦烧时间延长;硫化胶的耐热老化性能和耐臭氧性能优异,气密性能提高;成品轮胎的耐久性能提高。
英文摘要:
      The application of star branched brominated butyl rubber(BIIR)6222 in the inner liner of truck and bus radial tire was studied and compared with traditional BIIR2222.The results showed that,compared with BIIR2222 compound,the processability of BIIR6222 compound was better,the scorch time was extended,the heat resistance and ozone resistance of the vulcanizate were excellent,and the air tightness prolonged.The durability of the finished tire improved.
