一种新型微纳米钴锌绿建筑装饰颜料的制备

Preparation of New Micro-nano Cobalt Zinc Green Architectural Decoration Pigment

采取溶胶-凝胶法,以六水合氯化钴(CoCl_(2)·6H_(2)O)、氯化锌(ZnCl_(2))为原料,制备了钴锌绿颜料前驱物.通过低温烧结,得到了一种新型钴锌绿微纳米建筑装饰颜料.研究了不同原料配比的呈色效果,结果表明,该颜料所呈现的颜色与CoCl_(2)·6H_(2)O的加入量呈正相关关系,随着CoCl_(2)·6H_(2)O加入量的不断增加,颜料颜色由浅绿色逐渐转变为深绿色,所得样品为微纳米颜料.

The precursors of cobalt zinc green pigments were prepared by sol-gel method with cobalt chloride hexahydrate(CoCl_(2)·6H_(2)O)and zinc chloride(ZnCl_(2))as raw materials.A new type cobalt zinc green micro-nano architectural decoration pigments was obtained by low temperature sintering.The color effect of different ratio of raw materials was studied.The results showed that the color of the pigment was positively correlated with the addition amount of CoCl_(2)·6H_(2)O.With the increase of the addition amount of CoCl_(2)·6H_(2)O,the color of the pigment gradually changed from light green to dark green,and the samples obtained were micro-nano pigments.
