According to the requirements of energy conservation and emission reduction in China, combined with the characteristics of phase-change material, the phase-change material was incorporated into the traditional cement mortar concrete to prepare a new type of wall material. In this regard, for preparation of a new kind of energy-saving material, lauric acid, paraffin and expanded perlite were used as raw materials, the composite material was prepared by the method of physical fusion; and then the performance of the prepared phase-change material was tested by DCS thermal analysis, durability test and compressive strength test method. Through the above test, it's concluded that, with the increase of the phase change material dosage, the temperature regulating property of the material increases gradually, but the compressive strength decreases gradually. Therefore, the phase-change material should be properly added in the wall material, which can greatly improve the wall temperature control ability and achieve the purpose of energy saving and emission reduction.%针对目前国家提出的节能减排要求,结合相变储能材料的特点,将相变材料掺入到传统的水泥砂浆混凝土中,制备一种新型的墙体节能材料.对此,为实现对新型节能材料的制备,选取月桂酸、石蜡、膨胀珍珠岩等作为原材料,采用物理融合法对复合材料进行制备;然后通过DCS热分析测试、调温能力试验、抗压强度测试等方法对制备的相变材料性能进行测试.通过上述的测试,得出随着相变材料添加量的增加,材料的调温性能逐步提高,其抗压强度逐步减小.由此得到,在墙体材料中应适当加入相变材料,可极大的提升墙体温控调节能力,达到节能减排的目的.
