摘要

摘要: 采用溶胶-凝胶法制备棕榈醇-棕榈酸-月桂酸/SiO₂复合材料。利用响应面法研究了无水乙醇用量、去离子水用量以及棕榈醇-棕榈酸-月桂酸用量对棕榈醇-棕榈酸-月桂酸/SiO₂复合材料热湿综合性能的影响，并对棕榈醇-棕榈酸-月桂酸/SiO₂复合材料的制备工艺参数进行了优化。结果表明，各因素对性能影响的主次顺序为：无水乙醇用量>棕榈醇-棕榈酸-月桂酸用量>去离子水用量；在本研究的各参数范围内，优化方案是无水乙醇用量（与正硅酸乙酯的物质的量比）为9.11、去离子水用量为5.21、棕榈醇-棕榈酸-月桂酸用量为0.52。优化棕榈醇-棕榈酸-月桂酸/SiO₂复合材料具有良好的热湿综合性能，即相对湿度50%时，平均平衡含湿量为0.102 0 g/g，相变温度为26.81~28.52℃，相变焓为95.69 J/g，属于微米级有机相变芯材/无机基体复合材料。

Abstract: Hexadecanol-palmitic acid-lauric acid/SiO₂ composite materials can be prepared by sol-gel method. The effect of absolute alcohol amount, deionized water amount and hexadecanol-palmitic acid-lauric acid amount on heat & moisture comprehensive property of hexadecanol-palmitic acid-lauric acid/SiO₂ composites, and the preparation technology parameters for hexadecanol-palmitic acid-lauric acid/SiO₂ composite materials was optimized. The results show that primary and secondary sequence of factors is the effect of absolute alcohol amount is obviously more significant than that of hexadecanol-palmitic acid-lauric acid amount, and the effect of hexadecanol-palmitic acid-lauric acid amount more significant than that of deionized water amount. Within the ranges of parameters in this study, absolute alcohol amount (mole ratio to tetraethyl orthosilicate) is 9.11, deionized water amount is 5.21 and hexadecanol-palmitic acid-lauric acid amount is 0.52. Hexadecanol-palmitic acid-lauric acid/SiO₂ composite materials have the best heat-moisture comprehensive performance in the range of human comfort, i.e. average equilibrium moisture content is 0.102 0 g/g in relative humidity 50%, phase change temperature is 26.81-28.52℃, phase change enthalpy is 95.69 J/g, and belong to micron organic phase change core materials/inorganic substrate composite materials.
