    蓄热调温石蜡相变微胶囊的制备及性能

    • 摘要: 采用界面聚合法,以甲苯2,4-二异氰酸酯和哌嗪为反应单体、30号相变石蜡为芯材,制得了一种智能纺织品用蓄热调温相变微胶囊。通过红外光谱、扫描电镜、差示扫描量热仪对微胶囊的化学组成、形貌和蓄热性能进行了表征,测试了其耐热和耐溶剂性。结果表明:所得微胶囊主要为球形,表面光滑,平均粒径为10.6μm,对w=0.40的NaOH溶液、w=0.60的H2SO4溶液、无水乙醇、丙酮稳定,能被甲苯、二甲基甲酰胺、乙醚破坏。相变潜热为118 J/g,石蜡在微胶囊中的质量分数为84%。

       

      Abstract: Thermal energy storage and temperature conditioning microencapsulated phase change material (MEPCM) for smart textiles was prepared by interfacial polymerization technique. Toluene2,4diisocyanate and piperazine were used as monomers, and 30# paraffin was used as core material. Chemical composition, surface morphology and thermal energy storage of the MEPCM were studied by FTIR spectrum, scanning electron micrograph and differential scanning calorimeter analysis. Results indicate that the MEPCM prepared by interfacial polymerization technique is mostly spherical, which has lubricious surface with the average diameter of 10.6 μm. MEPCM is stable in NaOH solution (w=0.40), H2SO4 solution (w=0.60), ethanol and acetone while can be destroyed by toluene, dimethylformamide and ether. Latent heat of the MEPCM is 118 J/g. Mass content of the paraffin in the MEPCM is 84%.
