Abstract  

Under ultrasonic effect, used capric acid (CA) and lauric acid (LA) mixed to synthesize organic binary fatty acid as phase change materials, porous diatomite materials as the carrier , a kind of porous carries phase change material with various mass fraction of CALA(35%、40%、45%、50%、55%)was prepared via melting method to utilize adsorption characteristics of porous diatomite. Performance of temperature controlling and moisture absorption and desorption of porous carries phase change material was tested by coolingstep curve and isothermal moisture absorption and desorption method respectively, and the comprehensive performance of temperature and humidity was evaluated. Meanwhile its pore structure, phase change temperature and phase change latent heat, morphology, structure and thermal stability were characterized by mercury intrusion porosimetry(MIP), differential scanning calorimetry (DSC), scanning electron microscope (SEM), fourier transform infrared (FTIR) and thermogravimetric(TG). The results showed that the diatomite is welldeveloped pore structure, and when CALA adsorption amount reach 45%, the phase change temperature of porous carrier phase change material is 17.92℃ to 22.20 ℃, phase change latent heat is 30.88 J/g to 32.97 J/g . It also has good thermal reliability under the 140 ℃. The composite materials not only have advanced thermal performance but also humidity effect as to meet the temperature and moisture controling requirements of the building indoor.

多孔载体相变材料的热湿综合性能

以癸酸（CA）和月桂酸（LA）在超声波作用下混溶制备的二元有机脂肪酸为相变材料，多孔硅藻土材料为载体，利用多孔硅藻土的吸附特性，使用熔融法制备相变材料质量分数不同（35%、40%、45%、50%、55%）的多孔载体相变材料，分别采用步冷曲线法和等温吸放湿法对多孔载体相变材料的控温性及吸放湿性进行测试，并对热湿综合性能进行评价.同时利用压汞法（MIP）、差示扫描量热法（DSC）、扫描电镜（SEM）、红外光谱（FTIR）、热重（TG）等手段对多孔载体相变材料的孔结构、相变温度、相变潜热、形貌、组成和热稳定性进行分析.结果表明，硅藻土孔隙发达，对CALA的物理吸附质量达到45%时，多孔载体相变材料的相变温度在17.92～22.20 ℃，相变潜热在30.88～32.97 J/g；在温度为140 ℃以下具有良好的热稳定性，该复合材料具有满足建筑室内对相变材料热性能要求，而且具有良好的湿效应.
