摘要: 本论文针对纺织品护肤功能整理,采用界面聚合法,以甲苯二异氰酸酯(TDI)和聚乙二醇(PEG)为预聚单体,研制了聚氨酯型维生素E护肤微胶囊。探讨了扩链反应温度、PEG种类、芯壁质量比对微胶囊化效果的影响。结果表明:选取60℃、PEG400为反应单体、芯壁质量比为1/1.25时,制备的微胶囊粒径分布窄且粒径小,具有较高的微胶囊化产率和适当的有效载量。扫描电镜和动态粒径分析表明,优选工艺下制备的微胶囊呈规则的球状,粒径分布在260~2000nm,平均粒径在500~600nm,适用于纺织品护肤整理。

Abstract: Vitamin E (VE) core polyurethane microcapsules were successfully prepared via interfacial polymerization of polyurethane with toluene diisocyanate (TDI) as the isocyanate, polyethylene glycol as the polyol. The factors affecting microencapsulation effectiveness of VE were studied, such as chain-extending reaction temperature, molecular weight of PEG, and mass ratio of core to shell. Based on the present research, the microcapsules have a small narrow particle size distribution and a high yield and appropriate effective load, which are prepared with PEG400 as the polyol at 60℃and the mass ratio of 1/1.25. SEM and dynamic particle size analysis showed that VE microcapsules have smooth surfaces and spherical appearances, the mean particle size of 500~600 nm and distribution of 260~2000 nm.

Key words: microcapsules , polyurethane , vitamin E , skin-care textiles
