| 中文摘要: |
| 研究高效气体阻隔剂AT-200在轮胎气密层胶[溴化丁基橡胶（BIIR）/天然橡胶并用胶]中的应用。结果表明：在轮胎气密层胶中添加气体阻隔剂AT-200，胶料的门尼粘度略有减小，焦烧时间延长，硬度和耐热老化性能变化不大；随着气体阻隔剂AT-200用量增大，胶料的气密性逐渐提高，但拉伸强度、撕裂强度和弹性稍有降低；加入适量气体阻隔剂AT-200并适当减小BIIR用量，可以有效降低胶料体积成本。 |
| 英文摘要: |
| The application of high-efficiency gas barrier agent AT-200 in tire inner liner compound which was bromobutyl rubber（BIIR）/natural rubber（NR） blend was investigated. The results showed that with gas barrier agent AT-200，the Mooney viscosity of the compound was slightly reduced，the scorch time was prolonged，and the hardness and heat aging resistance changed little. With increase of the addition level of gas barrier agent AT-200，the air tightness of the compound gradually increased，but the tensile strength，
tear strength and elasticity decreased slightly. With optimized amount of gas barrier agent AT-200 and less amount of BIIR，the cost of the compound was reduced. |
