| 中文摘要: |
| 研究白炭黑/炭黑填充的新型高性能溶聚丁苯橡胶（H-SSBR）的各项性能以及填料在硫化胶中的微观分布，并在较佳白炭黑/炭黑并用比下，研究H-SSBR/天然橡胶（NR）并用比对胶料性能的影响。结果表明：随着白炭黑/炭黑并用比的减小，H-SSBR胶料的拉伸强度、拉断伸长率、压缩疲劳温升和耐磨性能提高，抗湿滑性能降低，滚动阻力增大；电镜照片表明，炭黑与白炭黑相互镶嵌分布在H-SSBR橡胶基体中，形成交织的填料网络，可发挥出双相填料的作用。在H-SSBR中并用适量NR，胶料的焦烧时间和正硫化时间缩短，拉断伸长率、撕裂强度和压缩疲劳温升提高，耐磨性能、抗湿滑性能和滚动阻力降低。在H-SSBR中并用适量NR可获得加工和使用性能较佳的绿色轮胎胎面胶。 |
| 英文摘要: |
| The properties of silica/carbon black-filled new type of high-performance solution polymerized styrene-butadiene rubber（H-SSBR） as well as the microscopic distribution of filler in the vulcanizate were studied.Besides，on the preferred blend ratio of silica/carbon black，the effect of the ratio of H-SSBR/NR/natural rubber（NR） on the performance of compound was investigated.The results showed that as the ratio of silica/carbon black reduced，the tensile strength，elongation at break，compression fatigue temperature and abrasion resistance of the H-SSBR compounds were improved，wet skid resistance was reduced，and rolling resistance was increased.TEM photographs showed that carbon black and silica particles embedded into H-SSBR matrix and formed the interweaving networks，which serves as two-phase filler.When H-SSBR blends with moderate NR，the scorch and curing time of compound were shorted，elongation at break，tear strength and compression fatigue temperature were increased，while there was a slight drop in wear resistance，rolling resistance and wet skid resistance.When H-SSBR blends with moderate NR，it would have a better processing and using performance in green tire tread. |
