摘要
合成了一系列ＮＣＯ／ＯＨ＜１的聚醚氨酯样品，借助动态粘弹仪讨论了交联密度、软硬段种类以及软硬段相对含量对聚醚氨酯动态力学性能和阻尼性的影响。结果表明，在ＮＣＯ／ＯＨ＜１的情况下，适当的软硬段组成配比可以获得高阻尼、宽温域（△Ｔ_（０．６）＞１００℃）的优良阻尼材料。
A series of polyether based polyurethane composition with NCD/OH<1 were prepared. By using the visco-elastometer,the vibration damping properties which effected by crosslink density, chemical compositions and hard segment contents were discussed.At NCO/OH<1,a higher damping material over wide temperature ranges(△T0.6>100 ℃) was obtained.
