受阻胺/热塑性聚氨酯复合材料的结构与性能研究

对受阻胺/热塑性聚氨酯复合材料的结构和性能进行研究。结果表明，受阻胺GW-622均匀分散在受阻胺GW-622/TPU复合材料中，受阻胺GW-944在受阻胺GW-944/TPU复合材料存在少量团聚体；随着受阻胺用量的增大，受阻胺/TPU复合材料高温区的阻尼性能显著提高；与TPU相比，复合材料的拉伸强度大幅下降。;The structure and properties of hindered amine/TPU composites were studied.The results showed that the hindered amine GW-622 was uniformly dispersed in the composites，while a few hindered amine GW-944 agglomerates existed；as the addition level of hindered amine increased，damping property of the composites in high temperature range improved significantly；tensile strength of the composites was decreased significantly compared with that of TPU
