| Abstract: |
| 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. |
