采用微胶囊技术制备空囊材料,以减少材料的导热性能,从而达到保温、节能降耗和提高材料性能的目的.以三聚氰胺为壁材,空气(或二氧化碳气体)为芯材,司盘-60为乳化剂,采用锐孔法和乳化缩聚技术制备涂料用微胶囊仿瓷乳液.以涂料用微胶囊的外形、粒径大小,涂料用微胶囊仿瓷乳液稳定性、导热系数为评价指标,对涂料用微胶囊仿瓷乳液制备方法、工艺条件及乳液性能进行了研究.结果表明:方法可行,工艺简便,经济;涂料用微胶囊仿瓷乳液保温性能较佳,且具有良好的仿瓷性能.%The microcapsule ceramic -like emulsion used for coating was prepared using melamine as wall,air (or carbon dioxide) as core and Span -60 as emulsifier by combining the orificing method and emulsification condensation polymerization technique. The profile, particle size, stability of microcapsule ceramic -like emulsion and its heat transfer coeffcient were used as evaluating criteria to study the preparation technology microcapsule emulsion for coating and its properties. Results showed the method was simple feasible and economic, which could be used to provide a coating with good heat insulation performance and ceramic -like effect.
