| 中文摘要: |
| 将全钢载重子午线轮胎气密层胶主体材料由并用比为80/20的溴化丁基橡胶（BIIR）/天然橡胶（NR）并用体系改为全BIIR，研究气密层胶的性能变化。结果表明，与BIIR/NR气密层胶相比，BIIR气密层胶的气密性和耐热老化性能好，加工性能略差，但通过增加混炼段、降低排胶温度等措施，胶料的加工性能改善，压延半成品和成型接头质量提高。 |
| 英文摘要: |
| Current inner liner of TBR tire was produced using blends of BIIR/NR with a blending ratio of 80/20.The purpose of this study was to investigate properties of inner liner compound with only BIIR as rubber material.The experimental testing results showed that the air tightness and heat aging resistance of BIIR compound were better than the BIIR/NR blend.However，the processing properties of BIIR compound were slightly worse comparing with the blend.In order to improve the processing properties of BIIR compound and quality of semi-finished products and joints，it was recommended to use more mixing stages and reduce the discharge temperature. |
