中文摘要:
      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。
英文摘要:
      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.
