| 研究硫化体系对白炭黑胎面胶硫化特性、物理性能、动态力学性能及轮胎硫化效率和性能的影响。结果表明：减小防焦剂CTP用量、增大促进剂DPG用量以及采用促进剂TBzTD，可提高胎面胶的硫化效率，在保证交联密度接近的情况下，胎面胶的物理性能和动态力学性能得到保证；采用回弹值测试试样模拟胎面胶硫化时的消泡情况，其结果与轮胎硫化时的消泡情况一致；调整胎面胶的硫化体系以缩短轮胎的硫化时间可使轮胎某些部件的过硫程度降低，轮胎的高速性能、耐久性能、滚动阻力和干地制动性能得到保证或改善。 |
| 英文摘要: |
| The effect of vulcanization systems on the vulcanization characteristics，physical properties，and dynamic mechanical properties of the silica tread compounds，and vulcanization efficiencies and performance of the tires was studied.The results showed that reducing the amount of anti-scorching agent CTP，increasing the amount of accelerator DPG and using accelerator TBzTD，the vulcanization efficiency of the tread compound could be improve.While ensuring a similar crosslinking density，the physical properties and dynamic mechanical properties of the tread compound were guaranteed.Using rebound value test samples to simulate the defoaming situation of the tread compound during vulcanization，the results were consistent with the defoaming situation of the tire during vulcanization. After adjusting the vulcanization system of the tread compound to shorten the vulcanization time of the tire could reduce the degree of over sulfurization of certain components of the tire，the high-speed performance，durability，rolling resistance and dry braking performance of the tire were guaranteed or improved. |
