| 中文摘要: |
| 采用以天然橡胶（NR）、NR/顺丁橡胶（BR）和NR/BR/溶聚丁苯橡胶（SSBR）为基体的轮胎胎面胶配方，研究低滞后炭黑DZ13对3种硫化胶物理性能和疲劳破坏行为的影响。结果表明：低滞后炭黑DZ13部分替代炭黑N234后，NR，NR/BR和NR/BR/SSBR硫化胶的物理性能变化规律相似，即定伸应力略有增大、拉断伸长率和撕裂强度减小；耐磨性能、耐压缩疲劳性能和耐割口增长性能的变化依赖于基体橡胶；其中NR/BR硫化胶的屈挠疲劳次数提高，但疲劳破坏界面的微观形貌更加粗糙。 |

| The low hysteresis carbon black DZ13 was used to replace part of carbon black N234 in the tread compounds based on NR，NR/BR and NR/BR/SSBR，and the effect of DZ13 on the physical properties and fatigue failure behavior of the vulcanizates was investigated.The results showed that，the physical property change of three vulcanizates was similar，i.e.，the modulus increased slightly，elongation at break and tear strength decreased.The change in wear resistance，compression fatigue property and cut growth resistance depended on the rubber matrix type.For NR/BR vulcanizate，the flex property was improved，but the morphology of failure interface was rougher. |
