摘要:
选择月桂酸(LA)、肉豆蔻酸(MA)、棕榈酸(PA)作为储能材料制备三元脂肪酸低共熔物(LA-MA-PA),利用理论估算公式得到LA-MA-PA的组成比例和热性能参数。采用真空吸附法将不同质量的液态LA-MA-PA封装于膨胀珍珠岩(EP)的孔隙内制备出月桂酸-肉豆蔻酸-棕榈酸/膨胀珍珠岩复合相变材料(LA-MA-PA/EP),然后利用渗出圈法确定膨胀珍珠岩对于三元脂肪酸的最大担载量。通过扫描电子显微镜(SEM)、傅里叶变换红外光谱仪(FT-IR)、热分析仪(TG)和差示扫描量热仪(DSC)等对LA-MA-PA/EP的微观结构、化学稳定性、热稳定性和热性能进行了表征。结果表明:复合相变材料中LA-MA-PA和EP质量比为2:1时达到最大负载量,且脂肪酸能均匀密实地分布于EP的孔隙中; EP担载材料与相变材料LA-MA-PA之间无化学反应; LA-MA-PA/EP的相变温度和相变潜热分别为30.4 ℃ 和103.6 J/g,适合应用于夏季炎热地区的建筑领域; 将LA-MA-PA/EP应用于建筑围护结构中,在其工作温度领域质量损失率低,具有较好的热稳定性。
Abstract:
Lauric(LA),myristic(MA)and palmitic(PA)were chosen as phase change materials(PCMs)to prepare LA-MA-PA ternary eutectic mixtures for energy storage.Theoretical calculation was done for the mass ratio and the thermal properties of LA-MA-PA ternary eutectic mixtures.LA-MA-PA with different mass ratios was absorbed in expanded perlite(EP)by vacuum absorption to prepare four kinds of LA-MA-PA/EP composite phase change materials.The optimum mass ratio of LA-MA-PA to EP was undetermined by compared with imprints on the filter paper.The scanning electron microscope(SEM), Fourier transform infrared spectrometry(FT-IR), thermogravimetric analysis(TG), and differential scanning calorimetry(DSC)characterization indicated that the optimum mass ratio of LA-MA-PA to EP was 2:1. LA-MA-PA was uniformly absorbed in the porous network of EP by its porous structure,instead of any chemical reaction. The phase change temperature and the latent heat of the LA-MA-PA/EP composite PCMs were tested to be 30.4 ℃ and 103.6 J/g,respectively. The LA-MA-PA/EP composite PCMs had good thermal stability during their working temperature range, thus it could be used in the construction field.
