| 中文摘要: |
| 对比研究不同生产厂家的低玻璃化转变温度改性溶聚丁苯橡胶（SSBR）在电动汽车全天候轮胎胎面胶中的应用。结果表明：不同生产厂家的SSBR用于胎面胶中，胶料的硫化特性、物理性能和动态力学性能基本相当；试制的215/55R17 98 V轮胎的高速和耐久等性能满足企业标准要求，湿滑性能和滚动阻力性能分别达到欧盟标签法的B和A级，－7 ℃下轮胎的滚动阻力系数为7.8 N·kN-1。 |
| 英文摘要: |
| A comparative study was conducted on the application of low glass transition temperature modified solution styrene-butadiene rubbers（SSBR） from different manufacturers in the tread compounds of all-weather tire for electric vehicles.The results showed that when the SSBR from different manufacturers were used in the tread compounds，the vulcanization characteristic，physical properties and dynamic mechanical properties of the compounds were basically equivalent.The high-speed performance and durability of the trial-produced 215/55R17 98 V tire met the requirements of the enterprise standards，etc.The wet grip performance and rolling resistance grade reach level B and level A respectively according to the EU labeling law，the rolling resistance coefficient of the tire at -7 °C was7.8 N·kN-1. |
