摘要
通过在脂肪族聚氨酯链上引入阴离子基团，制备了对颜料润湿性和树脂相容性良好的水性通用树脂，并对助剂和颜料进行选择性研究，制得了汽车涂料用水性通用色浆。确定了DMPA（二羟甲基丙酸）最佳用量为3．0％～6．0％，功能性助剂用量为0．4％～0．8％，润湿剂用量为0．3％，分散剂用量为0．4％～0．7％，消泡剂用量为0．4％。
A waterborne universal resin with good pigment wettability and resin compatibility was prepared bv the introduction of anionic group on aliphatic polyurethane chain. And through the study of selective additives and pigments, a waterborne universal colorant for automotive coatings was prepared. The optimum amount of DMPA 3.0%-6.0%, functional additives 0.4%-0.8%, wetting agent 0.3%, dispersing agent 0.4%-0.7% and defoamers 0.4% were determined
