低温可逆变色微胶囊的制备及其在水性涂料中的应用研究

Study on the Preparation of Lower-Temperature Reversible Discoloration Microcapsule and the Application in Water Based Paint

以结晶紫内酯 /双酚A为变色组分 ,月桂醇为溶剂 ,将其在水中分散为粒径 10～ 10 0 μm的液滴 ,在其外部包覆一层明胶 /阿拉伯树胶 ,制得可逆变色颜料的微胶囊 ,将油性的变色颜料改性成为粉末 ,克服了原来油性颜料与水性涂料相容性差、分散困难的缺点。

Crystal violet lactone/diphenylol propane wass serviced as discoloration constituents and dodecanol as solvent,which were dispersed into 10～100 μm drops in water.By coating the drops with gelatin/Arabic gum,reversible discoloration microcapsule was prepared,which oiliness pigment was changed in powder,and so overcome the shortcomings that the oiliness pigment cann't be compatible with water based paint.
