| 中文摘要: |
| 研究废旧轮胎再生胶（简称再生胶）在轿车子午线轮胎胎侧胶中的应用。结果表明：随着再生胶用量的增大，胶料的硫化速度减慢，300%定伸应力、拉伸强度、回弹值明显减小，耐屈挠性能下降，滞后损失增大；在轿车子午线轮胎胎侧胶中加入5份再生胶，胶料的加工性能和物理性能基本不变，成品轮胎的高速和耐久性能满足国家标准要求，同时生产成本降低。 |
| 英文摘要: |
| The application of waste tire reclaimed rubber（referred to as reclaimed rubber） in the sidewall compound of passenger car radial（PCR） tire was studied.The results showed that with the increase of the amount of recycled rubber，the vulcanization speed of the compound was slower，the modulus at 300% elongation，tensile strength and rebound value were reduced obviously，the flexural resistance decreased，and the hysteresis loss increased.Addition 5 phr reclaimed rubber in the sidewall compound of PCR tire，the processability and physical properties of the compound changed little，the high-speed performance and durability of the finished tire met the requirements of national standard，while the tire production cost was reduced. |
