摘　　要：以环保充油乳聚丁苯橡胶SBR1723作对比,研究环保充油溶聚丁苯橡胶T2830在轮胎胎面胶中的应用。结果表明:与SBR1723/天然橡胶(NR)/顺丁橡胶(BR)胶料相比,T2830/NR/BR胶料的起硫速度略快、硫化速度略慢;拉断伸长率和撕裂强度较高,硬度、定伸应力和拉伸强度相当;抗湿滑和抗干滑性能相当,干操控性能略差。采用T2830/NR/BR胎面胶的轮胎高速性能、耐久性能和滚动阻力与采用SBR1723/NR/BR胎面胶的轮胎相当。T2830可以替代SBR1723用于轮胎胎面胶。The application of environmentally-friendly oil extended solution SBR T2830 in the tire tread was investigated, and compared with emulsion SBR SBR1723. Compared with SBR1723/NR/BR blend, the scorch time of T2830/NR/BR blend was a little shorter, the curing rate was slightly lower; the elongation at break and tear strength of T2830/NR/BR vulcanizates were higher, the hardness, modulus and tensile strength were similar, the slip resistance on wet and dry roads was also similar, and the driving performance on dry road was slightly worse. By using T2830/NR/BR in tire tread compound, the high speed performance, endurance performance and rolling resistance of the tire were similar to the tire with SBR1723/NR/BR. T2830 could be used to replace SBR1723 in tire tread compound.
