摘　　要：本文采用自行合成的四种铜酞菁有机胺类衍生物对酞菁蓝颜料进行了表面处理,得到了以下规律:颜料的临界润湿表面张力随着铜酞菁衍生物碳氢链长度的改变均有不同程度的下降;颜料的表面自由能、表面自由能的色散成分变化不大,而极性成分下降比较明显;颜料的粒度分布向小颗粒方向移动,经铜欧菁衍生物处理后的颜料在正辛醇、二甲苯中分散,粒径在4μ以下的颜料粒子重量百分比由空白样品的50.1%增加至88.4%和96.4%;经表面处理后的颜料,其流动性也普遍有所改善.The surface treatment of four derivatives of Copper Phthalocynine has been studied. The critical wetting surface tensions and the polar component of surface tensions are decreased with the increase of the lengths of the carbon chains of the derivatives. The length of hydrocarbon affects slightly the dispersion component of surface tension; the distribution of the size of the treated pigments tends to move from big size to the small one; and the fluidity after the treatments has generally been improved.
