摘要:
相变微胶囊的储能能力以及环保性是决定其应用价值的关键指标。选用熔点为28 ℃的石蜡芯材，通过原位聚合并结合除醛处理，制备低甲醛、高芯壁比的三聚氰胺甲醛（MF）相变微胶囊。通过红外光谱、差示扫描量热仪、扫描电镜等对MF相变微胶囊的结构、形貌和性能进行了表征，探究芯壁比对MF相变微胶囊热性能的影响。结果表明：石蜡经过微胶囊化后，不仅可以防止石蜡泄露，还能提高石蜡的热稳定性；MF相变微胶囊呈现良好的表面形貌，在水中具有良好的分散性；通过调控芯材与壁材的比例，MF相变微胶囊包覆率可高达93-3%，焓值为214-5 J/g；通过分批次加入三聚氰胺制备预聚体的方式，可有效地将MF相变微胶囊甲醛残留量从361-3 mg/kg降低至317-7 mg/kg，在此基础上添加40%的尿素可以将甲醛残留量进一步降低至121 mg/kg。
