水性有机颜料分散体制备技术（二）

Preparation Technique of Waterborne Organic Pigment Dispersion （Ⅱ）

文中论述了水性有机颜料分散体的制备技术;有机颜料水性分散体物理化学特性及表征;相关有机颜料着色剂主要类型及应用特性.为满足水性涂料及水性印墨对有机颜料分散体的要求,在颜料合成与后处理过程中,采用多种不同极性的改性剂或添加剂实施颜料表面改性处理,以提高颜料粒子表面极性及改进分散体的稳定性.

The paper discusses the preparation of aqueous organic pigment dispersion technology; the physical and chemical properties of organic pigments in aqueous dispersion; and application characteristics of the main types of relevant organic pigments colorant. In order to meet coatings and aqueous printing inks on the requirements of orgartic pigment dispersion, , we can use a variety of different polarity modifiers or additives to achieve the pigment surface modification treatment in the process of the pigment synthesis and post-processing, which can increase the pigment particle surface polarity and improve the stability of the dispersion.
