颜料黄81改性研究

本文在C I P Y 81 (颜料黄 81 )合成的基础上 ,用不同类型的表面活性剂对其实施表面处理 ,并研究了表面活性剂结构及添加量对C .I.P .Y .81性能的影响。结果表明 ,添加非离子表面活性剂和阴离子表面活性剂 ,例如OP - 7,OS - 1 5及红油 ,可以明显改善C .I.P .Y .81的色光、透明度、流动性及着色力等多项应用性能 ,通过试验得到了较佳的工艺性条件 ,较佳添加量为颜料量的 3%～ 5% (质量分数 )

Study on the Synthesis and Modification of Pigment Yellow 81

On the base of the syntheis of pigment yellow 81(C.I.P.Y.81)the pigment was treated on the surface using various surfactnats.The effects of structure and addition quantity of non-ionic and anionic surfactant on properties of C.I.P.Y.81(Benzidine Yellow 10G) were studied.The results showed that shade,transparency,flowability and color strength of C.I.P.Y.81,were obviously improved by adding 3%～5% of non-ionic and anionic surfactant,such as OP-7,OS-15 and sulfonated castor oil.The suitable condition was presented.
