摘要 以固体石蜡和液体石蜡熔融混合进行复配,复合石蜡的相变温度和相变焓都随固体石蜡含量的增加而升高,以固液比3 : 7制备的复合石蜡熔点为28.3℃,相变潜热为100.04kJ/kg.以此复合石蜡作为微胶囊的芯材,以甲苯2,4二异氰酸酯(TDI)和乙二胺为单体,OP-10为乳化剂,采用界面聚合法在复合石蜡表面包覆聚脲囊壁材料制备石蜡/聚脲相变微胶囊,用扫描电镜(SEM)观察了乳化搅拌速度和反应温度对相变微胶囊表面形貌的影响,并用红外光谱(FTIR)、热重(TG)和差示扫描量热法(DSC)对相变微胶囊进行了表征.实验结果表明:在乳化搅拌速度2000r/min、反应温度70℃时制备的石蜡/聚脲相变微胶囊颗粒呈球形分布,平均粒径在3~4μm范围内,分散均匀,颗粒表面光滑、致密,熔点为28.1℃,相变潜热为58.4kJ/kg,包覆效率为87.5%.

Abstract:The composite paraffin was obtained by mixing solid and liquid paraffin. DSC characteristic results show the melting point and the enthalpy of composite paraffin is increasing with the increase of solid paraffin content. The melting point of composite paraffin which prepared with solid/liquid mass ratio 3 : 7 is 28.3℃, the latent heat of phase change is 100kJ/kg. Microencapsulated paraffin/polyurea phase change materials were prepared through an interfacial polymerization method using composite paraffin with solid/liquid mass ratio 3 : 7 as core materials, 2,4 toluene diisocyanate (TDI) and ethylenediamine as monomers, OP-10 as an emulsifier. It was investigated the effect of the particle size of microcapsules on the emulsification stirring speed and polymerization reaction temperature by SEM, FTIR and TGA and DSC methods were used to characterize the microcapsules. The results show that paraffin/polyurea microencapsules prepared with the emulsification stirring speed of 2000r/min and the polymerization reaction temperature of 70℃ are spherical and smooth surface and the average particle size of 3-4μm. Its melting point of 28.1℃ is similar with that of composite paraffin 28.3℃, the enthalpy of 58.4kJ/kg is less than that of composite paraffin 100.04kJ/kg, and the encapsulation efficiency is 87.5%.
