摘要
以硬脂酸丁酯为相变材料、膨胀珍珠岩为载体,采用减压吸附法制备了定型相变材料,然后加入脱硫石膏和外加剂配制成相变砂浆。当定型相变材料添加的质量分数为15%(硬脂酸丁酯吸附的质量分数为45%)时制备的砂浆性能最好。对比相变砂浆和普通砂浆的降温曲线,相变砂浆具有温度调节功能,能够实现能源的合理利用。
Shape-stabilized phase change material （SSPCM） is prepared using the method of vacuum absorption with n-butyl stearate as phase change material and expanded perlite as matrix. The SSPCM is mixed with desulfurized gypsum subsequently to produce the phase change mortar. When the ratio of composite SSPCM to mortar is 15% by mass,which contains 45% of n-butyl stearate, the performance of the phase change mortar is the best. In comparison with the temperature dropping curves of ordinary insulation mortar, the temperature dropping curves of phase change mortar indicates that the desulfurized gypsum based phase change mortar has thermal adjustment function and could achieve energy reasonable use.
