| 中文摘要: |
| 采用3种不同牌号的炭黑分别搭配不同并用比的NR/BR，设计性能侧重点分别为机械强度、耐屈挠性能和生热性能的支撑胶配方，研究其对跑气保用轮胎零气压耐久性能的影响。结果表明：成品轮胎的零气压耐久性能与支撑胶的硬度和刚性相关性较强；在不同的胶料硬度水平下，支撑胶的耐屈挠性能和生热性能未表现出对成品轮胎零气压耐久性能的明显增益效果。 |
| 英文摘要: |
| Using three different kinds of carbon black to match NR/BR with different ratios separately，a support compound formula was designed with a focus on mechanical strength，flexural resistance and heat build-up performance，and the effect of the support compound on the zero-air pressure durability of run flat tire was studied.The results showed that the zero-air pressure durability of finished tires had a strong correlation with the hardness and rigidity of the support compound.The flexural resistance and heat build-up performance of the support compound with different hardness did not show a significant improvement effect on the zero-air pressure durability of the finished tire. |
