Low melt point paraffin was prepared by the compounding of solid paraffin with liquid paraffin, the water was dispersed into the low melt point paraffin by using SDBS as surface active agent, then epoxy resin was added to prepare water-containing phase change material. 以固体石蜡和液体石蜡进行复配制得低熔点石蜡,采用十二烷基苯磺酸钠(SDBS)作表面活性剂,将水分散于低熔点石蜡中,然后加入环氧树脂,制得含水型树脂基定形相变材料。
