对聚脲石蜡相变微胶囊壁材进行改性,增加其柔韧性,延长循环使用周期。用差示扫描量热仪(DSC)、红外光谱仪(FT-IR)和烘箱分别对微胶囊产物进行了分析和表征,结果表明:添加适中长度的柔性链段能提升壁材柔韧性和微胶囊的稳定性,使用循环周期大幅度延长;用换热器模型对比测试了微胶囊的储热保温性能,发现壁材改性微胶囊有较大的储热保温性能。 The polyurea paraffin phase change microcapsule wall material is modified to increase its flexibility and extend the cycle of use. The microcapsule products were analyzed and characterized by differential scanning calorimetry (DSC), infrared spectroscopy (FT-IR) and oven respectively. The results showed that adding moderate length of soft segment can improve the flexibility and microcapsules The stability of the microcapsules was greatly prolonged with the cycle time. The thermal storage and thermal insulation properties of the microcapsules were compared with the heat exchanger model. The thermal insulation properties of the microcapsules were found to be improved.
