| 摘 要： | 以聚乙烯醇为皮材、玫瑰香精为芯材、戊二醛为交联剂，采用界面聚合法合成醇醛树脂香精微胶囊，研究了反应温度、芯皮材质量比、乳化剂用量、交联剂用量等对合成的微胶囊形状及其缓释性能的影响；通过傅里叶红外测试、粒径分布测试等分析了产品的粒径大小及结构。结果表明：在温度为40℃，乳化剂质量为0.15g，皮材和芯材比为2：3，盐酸体积为1mL，戊二醛体积为2mL的情况下反应3h，可得到中值粒径为47.7716μm的微胶囊颗粒。

| Abstract: | Fragrant microcapsules was synthesized by interfacial polymerization using polyvinyl alcohol as sheath material,rose perfume as core,and glutaraldehyde as the crosslinking agent.The effects of reaction temperature,sheath /core ratio,dosages of emulsifier and crosslinking agent on the shape and control release properties of the microcapsules were studied.Fourier transform infrared spectroscopy was used to examine the particle size distribution and structure of the microcapsules.The results showed that microc... |
