软质聚氨酯泡沫塑料隔热性能研究

Study on the Insulation Property of Flexible Polyurethane Foam

研究了软质聚氨酯泡沫塑料隔热性能的影响因素。讨论了泡沫压缩率、泡沫密度、温度及泡沫吸水率与导热系数的关系 ,结果表明 ,温度、密度及吸水率是影响泡沫隔热性能的主要因素。

The factors influencing the thermal insulation of soft polyurethane foam were investigated.The relations between thermal conductivity and compression of the foam,temperatures,density and water absorption have been discussed.The results show that temperature,density and water absorption are the main factors.
