摘　　要：为降低聚氨酯硬泡(RPUF)反应温度,利用相变微胶囊(PCM)对RPUF进行改性。研究了PCM含量对RPUF反应温度、热稳定性、力学性能和导热系数的影响。结果表明:PCM含量越高,其吸热降温能力越强,但添加PCM会降低RPUF的热稳定性。随着PCM含量的增加,RPUF的压缩强度和导热系数先增加后降低,而剪切强度一直下降。In order to reduce the reaction temperature of rigid polyurethane foam(RPUF),phase change microcapsules(PCM)were used to modify RPUF.The effects of PCM content on the reaction temperature,thermal stability,mechanical properties and thermal conductivity of RPUF were studied.The results showd that,with the increase of PCM content,its heat absorption and cooling capacity increased.However,the addition of PCM reduced the thermal stability of RPUF.With the increase of PCM content,the compressive strength and thermal conductivity of RPUF first increased and then decreased,while the shear strength always decreased.
