摘要
本文采用了不同类型的表面活性剂对酞菁绿进行了表面处理，考察了不同极性基团，碳链长度，表面活性剂用量以及不同分散介质对颜料粒子的粒径分布的影响，发现以－ＯＨ、－ＮＨ２和ＣＯＯＨ作为锚固基团的Ｓｐａｎ和Ｔｗｅｅｎ类，脂肪胺和脂肪酸类表面活性剂均有利于酞菁绿颜料的细化。在锚固基团相同的条件下，碳链长度在１２～１８碳范围内随碳链增加有利于颜料的细化但作用不大。表面活性剂的最好用量为５％～７％。弱极性有机介质有利于酞菁绿颜料的分散。
Abstract In this paper,the surface treatment of Phthalocyanine Green G has been studied by use of different ionic and nonionioc surfactants.Surfactants with anchoring group-OH,-NH2,-COOH,are good dispersants for Phthalocyanine Green G such as Span,Tween,fatty amine and acid.The dispersion stability of Phthalocyanine Green G increases with hydrophobic chain increasing.Weak polar octanol is an effective dispersion medium for Phthalocyanine Green G.The addition of 5%～7% surfactant is suitable.
