摘要 以司盘-80、吐温-80和十二烷基硫酸钠合成不同配方的复合乳化剂,与SiO2为载体材料,棕榈醇-棕榈酸-月桂酸为相变材料,采用溶胶-凝胶法制备一系列相变调湿复合材料。利用激光粒度分析仪、扫描电子显微镜、傅里叶变换红外光谱仪、差示扫描量热仪和动态水分吸附分析仪研究不同复合乳化剂配方对相变调湿复合材料粒度分布、微观形貌、组成结构、热性能与湿性能的影响,分析复合乳化剂对相变调湿复合材料热性能与湿性能的影响机理。结果表明:以司盘-80、吐温-80和十二烷基硫酸钠为复合乳化剂制备具有良好热性能与湿性能的相变调湿复合材料,其相变材料质量分数达到70.34%~74.00%,在相对湿度为40%~60%之间的湿容量为0.0361~0.0390g/g。以司盘-80、吐温-80和十二烷基硫酸钠为复合乳化剂有效改善相变调湿复合材料的粒度分布与均匀程度,并且提高相变调湿复合材料的分散性。

Abstract:Sipan-80, Tween-80 and sodium lauryl sulfate were used to synthesize the compound emulsifier with different formulations, and SiO2 as the carrier, hexadecanol-palmitic acid-lauric acid as a phase change material,a series of phase change and humidity controlling composites were made by sol-gel method. Effects of different compound emulsifier formulations on particle size distribution, microstructure, composition structure, thermal properties and humidity properties were studied by LPSA, SEM, FTIR, DSC and DVS, the influence mechanism of compound emulsifier on thermal properties and humidity properties of phase change and humidity controlling composites was analyzed. The results show that with Sipan-80, Tween-80 and sodium lauryl sulfate as compound emulsifier, phase change and humidity controlling composites with good thermal properties and humidity properties were prepared, such as phase change material with mass fraction of 70.34% to 74.00%, and the moisture content with relative humidity between 40% and 60% is 0.0361-0.0390g/g. With Sipan-80, Tween-80 and sodium lauryl sulfate as compound emulsifier can effectively improve the particle size distribution and uniformity coefficient of phase change and humidity controlling composites, and improve the dispersion of phase change and humidity controlling composites.
