摘　　要：以密胺树脂为壁材,以十二醇和十四醇组成的复合醇为芯材,通过原位聚合法制备了微胶囊相变材料.通过正交试验考察了反应时间、反应温度、反应pH值和芯壳比对微胶囊相变材料反应收率的影响.结果表明:反应时间为4h,反应温度为70℃,反应pH值为6.0,芯壳比为1∶2.0时,反应收率最高,达到88.5%.微胶囊相变材料的外观呈球型,平均粒径为1.9μm;在25.5℃左右具有较好的调温作用,相变焓为63.9 J/g.Microencapsulated phase change materials were prepared by in-situ polymerization using melamine resin as wall material and compound alcohol as core material. The effects of reaction time, reaction temperature, pH and core-shell ratio on the conversion rate of microencapsulated phase change materials were investigated by orthogonal experiment. The results show that the highest conversion rate of 88.5% is obtained when the reaction time is 4 hours, reaction temperature is 70 ℃, pH is 6.0, and core-shell ratio is 1∶2.0. The microencapsulated phase change material is spherical with an average particle size of 1.9 μm. It has a good temperature regulation effect at 25.5 ℃, and its phase transition enthalpy is 63.9 J/g.
