摘要
考查了斯盘、吐温和脂肪胺三种不同类型的非离子表面活性剂，在氯苯和水中，对酞菁绿颜料进行表面处理后，其自由面能γｓ、表自由面能的色散成分γｄｓ变化不大，而表自由面能的极性成分γｐｓ变化明显，且随疏水链长度增加而下降。处理后的酞菁绿颜料，在正辛醇中其粒径均向窄分布小颗粒区间移动，得到易分散的颜料。处理过程所用介质，对处理后颜料表面的亲水、亲油性有很大影响。以水为介质得到在水中分散性好的颜料。以有机溶剂为介质得到在油中分散性好的颜料。
The surface treatment of phthalocynine Green in chlorobenzene has been studied by use of span, tween and fatty amines. The lengths of hydrophobic chains have a slight effect on the wetting critical surface tension and the dispersion component of surface tension of the treated pigment. The distribution of size of the treated pigment moves from big size region to small one. The polar component of surface tension decreases obviously with the increasing of length of hydrophobic chains. The disperse medium used for treating pigment, has an evident effect on the lypohydrophilic character. When water is taken as the disperse medium, the obtained pigment has a good dispersivity in water and when oil is taken as the medium, the obtained pigment has a good dispersivity in oil.
