摘要
制备了一种复合相变蓄热材料,该蓄热材料是由两种相变材料(硬脂酸和石蜡油)组成,通过物理吸附的方法将其复合在固态支撑材料中,通过实验分析了所研制的蓄热材料的相变点、相变热、热稳定性及微相结构等性能。测试结果表明该蓄热材料具有较高的相变潜热和较好的热稳定性。
A heat storage phase change composite material was prepared, based on two kinds of phase change materials (stearic acid and paraffin oil), and physically adsorbed by a solid skeleton material. The properties of the heat storage material including phase change temperature, phase change latent heat, thermal stability and microstructure were analyzed, and the results show that the composite material has higher latent heat and better thermal stability.
