| 中文摘要: |
| 采用机械共混法制备热塑性聚氨酯（TPU）/顺丁橡胶（BR）共混材料，并研究TPU/BR共混比对共混材料性能的影响。结果表明：TPU/BR共混材料的硫化特性和物理性能较BR显著改善；TPU/BR共混材料的流动性能与TPU/BR共混比成反比；TPU/BR共混材料的耐老化性能和热稳定性能较BR下降。 |

| Abstract：Thermoplastic polyurethane（TPU）/butadiene rubber（BR） blends were prepared by mechanical
blending，and the effects of TPU/BR blending ratio on the properties of the blends were studied. The results
showed that，the vulcanization characteristics and physical properties of TPU/BR blends were significantly
improved compared with those of BR，the fluidity of TPU/BR blends was inversely proportional to the
blending ratio of TPU/BR，and the aging resistance and thermal stability of TPU/BR blends were lower than
those of BR. |
