| 研究炭黑补强的自制星形溶聚丁苯橡胶（S-SSBR）/异戊橡胶（IR）并用胶并用比对胶料各项性能的影响。结果表明：S-SSBR与IR具有一定的相容性，IR可以改善S-SSBR的加工流动性能，增大胶料的硫化速率，改善S-SSBR的低温性能；随IR用量的增大，硫化胶的硬度和压缩生热降低，阿克隆磨耗量和拉断永久变形逐渐增大。磨耗形貌和物理性能的变化表明，当IR用量超过40份时，发生S-SSBR与IR的相转变；S-SSBR为连续相时，随着IR用量的增大，硫化胶的抗湿滑性能降低，滚动阻力变化不大。S-SSBR/IR并用比为80/20时，并用胶具有较优的综合性能。 |

| The influence of the blending ratio on the properties of self-developed star-shaped solution SBR（S-SSBR）/IR blends reinforced by carbon black was studied.The results showed that S-SSBR had good compatibility with IR，blending with IR improved the processing properties and low temperature properties of S-SSBR，and increased the cure rate.With increase of the addition level of IR，the hardness and compression temperature rise of the vulcanizates decreased，the abrasion resistance and tensile permanent set gradually increased.The change of wear surface morphology and physical properties showed that phase transition occurred while the adding level of IR reached 40 phr.When S-SSBR was in continuous phase，the wet-skid resistance decreased and rolling resistance changed little with the increase of the addition level of IR.When the blending ratio of S-SSBR/IR was 80/20，the blend had the better comprehensive properties. |
