摘要: 采用动态热力学分析方法研究了影响硬质聚氨酷泡沫塑料(RPUF)阻尼性能的因素,结果表明,未添加任何填料时,阻尼性能随着泡孔孔隙率的增加而增加;添加填料时,在相同孔隙率条件下阻尼性能随着填料含量的增加有所提高;体系交联密度的降低也有利于提高RPUF的阻尼性能。当纳米碳酸钙含量为5%(体积分数,下同)时,材料的损耗因子在一20 ~ 100℃范围内均在0.04以上,满足刚性阻尼材料的要求。

Abstract: The parameters affecting the damping property of rigid polyurethane foam (RPUF) were in-vcstigatcd.It showed that the damping factor increased with increasing porosity and cros、一linking dcnsity.八t the same porosity, the damping factor increased with increasing filler content. When the content
of nano-CaC03 was 5 vol%,the loss factor was above 0 .04 between一20一100℃.
