使用石蜡和颗粒状多孔介质膨胀珍珠岩,并在其外部包裹环氧树脂复合而成颗粒型复合储能相变材料,文中研究了固化温度、溶剂种类及用量对石蜡/膨胀珍珠岩复合相变材料制备的影响,使用扫描电镜对石蜡/膨胀珍珠岩复合相变材料的形貌进行表征。研究结果表明：以石蜡为相变储能材料的最佳制备工艺条件是：珍珠岩/环氧树脂=1∶0.2;环氧树脂/HDT31=1∶0.4;膨胀珍珠岩/石蜡复合相变材料颗粒包裹的非常均匀,形成的环氧树脂膜均匀致密,在50℃烘箱内干燥48 h,无石蜡渗出。

Granular composite material that expanded perlite impregated with paraffin wax as phase change material is enclosed with epoxy resin is fabricated.The effect of solvent and its ratio to the expanded perlit,the ratio of the perlite to epoxy resin,the ratio of epoxy resin to curing agent are investigated in the paper.The morphology of the composite is characterized by scanning electronic microscope.Th...
