两性表面活性剂及脂肪酸对联苯胺黄G的改性研究

MODIFICATION OF BENZIDINE YELLOW G WITH AMPHOTERIC SURFACTANT AND FATTY ACID

本文以两性表面活性剂和脂肪酸对联苯胺黄G表面改性，测定了颜料的流动性、润湿性和分散性。结果表明，添加脂肪酸后，颜料的流动性和在非极性介质中的润湿性和分散性有所提高；添加两性表面活性剂后，颜料的流动性及在极性、非极性介质中的润湿性和分散性均得以改善，并随活性剂用量的增加呈递增趋势。

The benzidine yellow G pigment was modified with amphoteric surfactant and fatty acid, and the flowing, wetting and dispersing properties of the modified pigment were determined. It has been shown that addition of fatty acid can improve the flowing, and wetting and dispersing ability of the pigment in non-polar system,and amphoteric surfactant can help the improvement of flowing and dispersing properties of pigment, which will improve with the increasement of addition of modifying agents.
