以马来海松酸酐缩水甘油酯型环氧树脂( MPTGE)为原料与聚乙二醇反应合成了一种与MPTGE具有相似分子结构的松香基非离子型表面活性剂( MP)，再以MP及其它5种常用表面活性剂乳化MPTGE作为嚢芯，正硅酸四乙酯( TEOS)为囊壁，采用溶胶-凝胶法制备了一种新型有机硅包覆环氧树脂微胶囊。研究了不同种类及用量的表面活性剂对微胶囊粒径及其分布的影响，并通过光学显微镜、扫描电镜、Zeta粒径测定等分析方法表征了微胶囊的表面形貌、粒径尺寸及分布。结果表明，表面活性剂MP有助于有机硅包覆环氧树脂微胶囊的形成；在MP用量为16.7%(质量分数)时，制备的微胶囊表面光滑致密、分散均匀。

A novel microcapsule was prepared from silica encapsulating maleopimaric acid glycidyl ester type epoxy resin ( MPTGE) by sol-gel process. In these microcapsules system, MPTGE was used as the core material, and tetraethyl orthosilicate ( TEOS) acted as the shell material. Some ionic, nonionic, macromolecular surfactants and a rosin-basd surfactant ( MP) which was synthesized from MPTGE and polyoxyalkylene were used as the stabilizer. The effects of different surfactants and concentrations on the particle size and distribution of the encapsulated microcapsules were investigated. The surface morphology, particle size and distribution of microcapsules were characterized by optical microscope, scanning electronic microscope and zeta size analyzer, respectively. Experimental results indicated that the surfactant MP synthesized from MPTGE was favorable to form TEOS encapsulating MPTGE microcapsules. The microcapsules had smooth and compact outer surface when the amount of MP was close to 16. 7 %.
