摘要 以脲醛树脂作为囊壁,添加氯化钾代替氯化钠作为微胶囊促进剂,采用原位聚合法制备了石蜡微胶囊。结果表明:石蜡微胶囊的平均粒径为16.8μm,囊壁厚度约为500nm。热重分析显示石蜡微胶囊比石蜡具有更好的热稳定性。石蜡微胶囊的相变温度为33.29℃,相变焓为128.51J/g,与添加氯化钠的微胶囊相比储热性能更好。

Abstract: Micro-encapsulated paraffin was prepared by in-situ polymerization method with urea-formaldehyde resin as shell and KCl as the microcapsulated accelerant.The experimental results showed that the microcapsules were successfully coated by urea-formaldehyde with 16.8μm of the mean particle size and 500nm of the size of capsule wall.The TGA results shown that the microcapsules had higher thermal stability than paraffin.The microcapsules showed the melt point and enthalpy were 33.29℃ and 128.51J/g,respectively,which were showed the higher thermal storage performance than the microcapsules added NaCl.
