【摘要】：采用细乳液界面聚合法制备双壳微纳米相变胶囊。以建筑石膏作为基体材料,将双壳微纳米相变胶囊掺入石膏基体材料中,制备石膏基双壳微纳米相变胶囊复合材料。对其进行吸放湿试验测试分析、储放热试验测试分析和耐久性测试分析。利用电子扫描显微镜和差示扫描量热仪研究其表观形貌、热性能。结果表明:双壳微纳米相变胶囊已经达到微纳米共存的效果,可以有效填充在石膏基材料的细小孔隙中。当双壳微纳米相变胶囊掺量为30%时,石膏基双壳微纳米相变胶囊复合材料具有显著的吸放湿效果和储放热效果。石膏基双壳微纳米相变胶囊复合材料具有良好的耐久性。
[Abstract]:Double-shell micro-nano phase change capsules were prepared by interfacial polymerization of fine emulsion. Using building gypsum as the matrix material, the double shell micronano phase change capsule was mixed into the gypsum matrix material to prepare the gypsum based micronano phase change capsule composite. The moisture absorption test, heat storage test and durability test were carried out. The morphologies and thermal properties of ESM and DSC were studied by means of electron scanning microscope and differential scanning calorimeter. The results show that the double shell micronano phase change capsules have achieved the effect of coexistence of micro and nano particles and can be effectively filled in the fine pores of gypsum based materials. When the content of double shell micronano phase change capsule is 30%, the gypsum based double shell micro and nano phase change capsule composite has remarkable effect of moisture absorption and heat release. Gypsum-based double-shell micro-nano-phase change capsule composites have good durability.
