| 中文摘要: |
| 研究稀土顺丁橡胶（牌号BR1243Nd）在轿车子午线轮胎胎侧胶中的应用。结果表明：在胎侧胶中以BR1243Nd全部替代镍系顺丁橡胶（牌号BR9000），并调整环保橡胶油的用量，胶料的加工性能相当，硫化胶的回弹值增大，耐屈挠龟裂性能和玻璃化转变温度相当，损耗因子减小；成品轮胎的高速性能和耐久性能提高，且胶料成本降低。 |
| 英文摘要: |
| The application of rare earth butadiene rubber（brand BR1243Nd） in the sidewall compound of passenger car radial tire was investigated.The results showed that replacing nickel based butadiene rubber（brand BR9000） with BR1243Nd in the sidewall compound and adjusting the amount of environmentally friendly rubber oil，the processability of the compound was comparable，the rebound value of the vulcanizate increased，the flexural cracking resistance and glass transition temperature were comparable，and the loss factor was decreased.The high-speed performance and durability of finished tires were improved，and the cost of compound was reduced. |
