摘要：

以蜂蜡为微胶囊芯材,以甲苯-2,4-二异氰酸酯（TDI）和乙二胺（EDA）为单体,以辛基酚聚氧乙烯醚（OP-10）为乳化剂,采用界面聚合法制备聚脲蜂蜡相变微胶囊。探讨乳化剂用量、单体摩尔比和反应温度等因素对聚脲蜂蜡相变微胶囊的影响,并表征其包覆效果。结果表明,在乳化剂质量分数为2.40%,n（TDI）∶n（EDA）=1.2∶1.0,反应温度为70 ℃的条件下制备的聚脲蜂蜡相变微胶囊的平均粒径为70.3 μm,耐热温度为210 ℃,相变温度为41 ℃,相变潜热为59.55 J/g。

Abstract:

Polyurea microcapsules containing beeswax as the core material were prepared by interfacial polymerization. Toluene diisocyanate （TDI） and ethylene diamine （EDA） were used as monomers and octylphenol polyoxyethylene （10） ether （OP-10） was used as emulsifier. The effects of emulsifier dosage, molar ratio of monomers and reaction temperature on polyurea/beeswax phase change microcapsules were studied. The effectiveness of microencapsulation was also analyzed. The results showed that when the emulsifier mass fraction is 2.40%, n（TDI）∶n（EDA） is 1.2∶1.0 and the reaction temperature is 70 ℃, the average particle size of polyurea/beeswax microcapsules prepared under such condition is 70.3 μm, while the heat-resistance temperature, phase change temperature and latent heat of phase change are 210 ℃, 41 ℃, and 59.55 J/g, respectively.

Key words: beeswax, polyurea, phase change microcapsule, interfacial polymerization
