| 中文摘要: |
| 研究EXXPRO对全溴化丁基橡胶（BIIR）胶料气密性的影响。结果表明：采用EXXPRO等量部分或全部替代BIIR后，胶料的交联密度增大，硫化胶的气密性和动态力学性能提高，生热降低；成品轮胎的气密性提高。对甲基苯乙烯基团含量和橡胶交联密度是影响BIIR胶料气密性的主要因素。 |
| 英文摘要: |
| The effect of EXXPRO on the air tightness of full brominated butyl rubber（BIIR） compound was studied.The results showed that by using EXXPRO to replace part or whole BIIR in equal weight，the crosslinking density of the compound increased，the air tightness and dynamic mechanical properties of the vulcanizate improved，and the heat build-up decreased.The air tightness of the finished tire was improved.P-methylstyrene group content and rubber crosslinking density were the main factors affecting the air tightness of BIIR compound. |
