介绍了以聚苯乙烯-丁二烯-苯乙烯（SBS）、酯型聚氨酯（TPU-EX）和醚型聚氨酯（TPU-ER）为基材，通过熔融共混制备新型热塑性复合弹性体材料。研究了在不同成分下其形貌、热阻、力学性能和动态阻尼性能之间的关系。SBS/TPU复合弹性体材料的一个重要特点是透明均匀，因为SBS和TPU的折射率一致，颗粒非常小，尺寸分布很窄。此外，随着TPU加入量的增加，SBS热老化前后的热阻、动态阻尼性能和力学性能均有所改善，表明SBS与TPU共混符合复合规律。SBS/TPU复合弹性体材料具有较好的高频动态阻尼性能。
We present the preparation of novel thermoplastic composites elastomer material based on poly (styrene–butadiene–styrene) (SBS), ester-type polyurethane (TPU-EX) and ether-type polyurethane (TPU-ER) materials via melt blending. A series of studies were conducted on the relationship between their morphology, thermal resistance, mechanical properties, and dynamic damping properties, given different compositions. An important feature of the SBS/TPU composites elastomer materials of all compositions is their uniform transparency, because the particles are very small with a narrow size distribution and the refractive indices of SBS and TPU are coincide. Additionally, the thermal resistance, dynamic damping properties and mechanical properties of SBS before and after thermal aging are improved as the amount of added TPU is increased, suggesting that blending SBS with TPU is consistent with the compound rule. In addition, the SBS/TPU composites elastomer materials have better dynamic damping properties at high frequency.
