摘　　要：以石蜡为囊芯,脲醛树脂为囊壳,通过原位聚合法制得了微胶囊。研究了脲醛预聚体的生成和脲醛预聚体的固化2个阶段的工艺条件对微胶囊形成的影响。显微观察微胶囊形貌完整。涂膜隔热性能测试结果表明,该种微胶囊具有明显吸热性能,可作为隔热添加剂使用。With paraffin as core material, urea-formaldehyde resin as shell material, by means of in-situ polymerization, microcapsules were prepared. The effects of parameters during prepolymer's forming and its solidifying process are researched. The optical morphography shows that the microcapsules are integrated. The measurement of coating within the microcapsules proves the heat insulation property, and the microcapsules can be used as heat insulation additive.
