| 中文摘要: |
| 研究国产溴化丁基橡胶（BIIR）2302在全钢载重子午线轮胎气密层胶[天然橡胶/BIIR并用胶（并用比为20/80）]中的应用。结果表明：与采用进口BIIR2222的气密层胶相比，采用BIIR2302的气密层胶硫化速度和加工安全性相当；气密性差异不大，拉断伸长率较大，其他物理性能相近；工艺性能较好；成品轮胎耐久性能略好。BIIR2302完全可以替代BIIR2222用于全钢载重子午线轮胎气密层胶中。 |
| 英文摘要: |
| The application of domestic brominated butyl rubber（BIIR） 2302 in the innerliner compound [blend of natural rubber/BIIR（blend ratio 20/80）] of TBR tire was studied.Compared with imported BIIR 2222，the curing speed and processing properties of the BIIR 2302 compound were similar，the air tightness of the innerliner was also similar，the elongation at break was larger，other physical properties were similar，process property was better，and the durability of the finished tire was slightly better.It was concluded that BIIR2302 instead of BIIR 2222 could be used in the innerliner compound of TBR tire. |
