【摘要】 本文用流变性方法分析了酞菁蓝－醇酸清漆分散体系的分散稳定性，同时用沉降和透射电镜等直接方法对分散体系的分散稳定性进行了确证。结果表明，添加了９４３颜料分散剂的酞菁蓝－醇酸体系的分散稳定性变好，其流动行为趋近宾汉流体；而未加分散剂的酞菁蓝－醇酸清漆体系中，酞菁蓝粒子易沉降、返粗，其流动曲线形成明显的触变环。更多还原

【Abstract】 The dispersion stability of phthlo cyanine blue-alkyd clear coating system is analysed by rheology approach,and confirmed with direct determination, such as sedimentation and electronic microscope. It has been shown that the dispersion stability increases with the addition of 943 pigment dispersant and flow behavior acts like Bingham fluids. However, the phthalo cyanine bluealkyd dispersion system without dispersant will show sedimentation of phthalo cyanine blue and flocculation,and an obvious closed thixotropic loop.更多还原
