掺月桂酸
摘要： 以改性膨胀蛭石为吸附材料，以月桂酸和硬脂酸为相变材料，通过熔融共混法与真空吸附法制备定型复合相变材料，然后将其掺入砂浆中制备得到蓄热砂浆。结果表明：复合相变材料经过1000次循环后相变焓为167.6 kJ/kg，变化率仅为3.6%，热稳定性良好，无渗漏现象，掺入30%体积含量复合相变材料的砂浆28 d强度为9.2 MPa。掺有该定型相变材料的蓄热砂浆具有优异的热力学性能，完全可以应用于建筑物围护结构来调节室内温度。

Abstract: The modified expanded vermiculite is used as the adsorbent material, and the lauric acid and stearic acid are used as the phase change materials. The shaped composite phase change material is prepared by melt blending method and vacuum adsorption method, and then mixed into the mortar to prepare the heat storage mortar. The results show that the phase change enthalpy of the composite phase change material after 16 cycles is 167.6 kJ/kg, the change rate is only 3.6%, the thermal stability is good, no leakage phenomenon, and the 28 d strength of the mortar with 30vol% composite phase change material is incorporated. It is 9.2 MPa. The heat storage mortar mixed with the shaped phase change material has excellent thermodynamic properties and can be completely applied to the building envelope to adjust the indoor temperature.
Key words: phase change material, expanded vermiculite, shaped phase change material, thermal storage mortar
