PREPARATION OF COMPOSITE MATERIAL OF GYPSUM-BASED DOUBLE-SHELL MICRO-NANO PHASE CHANGE CAPSULES AND PERFORMANCE RESEARCH OF TEMPERATURE-HUMIDITY CONTROL

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。

The miniemulsion interfacial polymerization method was used to prepare the double-shell micro-nano phase change capsules which were mixed with building gypsum to prepare the composite material of gypsum-based double-shell micro-nano phase change capsules. It was tested and analyzed by absorption and desorption test, thermal performance test and durability test. The apparent morphology and thermal performance were analyzed by scanning electron microscope （SEM） and differential scanning calorimeter （DSC）, respectively.The results show that double-shell micronano phase change capsules have reached the effect of the micro/nano coexistence, which can be filled into tiny pore of gypsum-based material. The composite material of gypsum-based double-shell micro-nano phase change capsules with mass content of 30% of double-shell phase change micro-nano capsules can provide good absorption and desorption effect, good thermal performance and good durability.
