颜料黄81改性研究

Study on the Synthesis and Modification of Pigment Yellow 81

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 )

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.
