摘　　要：以氧化铁和酞菁蓝为颜料,考察了不同分散剂、增稠剂种类及用量对水性色浆贮存稳定性的影响,优化了无树脂色浆制备工艺,通过实验验证了提高体系贮存稳定性的条件。适宜的颜料含量、合适的润湿分散剂和增稠剂种类及用量、合理的细度范围,均能在不同程度上影响颜料粒子沉降,改善体系贮存稳定性。The effects of the varieties and levels of dispersants and thickeners on the storage stability of the waterbased resin -free colorants have been investigated with the iron oxide and phthalocyanine blue as the pigments. Meanwhile, the requirements to improve the storage stability of system were indentified through the experiments with the optmized production process. The storage stability of colorants could be improved with the utility of optimum content of pigments, suitable types and levels of dispersants and thickeners,and the reasonable fineness, which have great effects on the settlement of the waterbased colorants.
