摘　　要：目的研究分析不同配方和比例原材料对水基丝印油墨性能和印刷适性的影响。方法分别以聚氨酯乳液、丙烯酸树脂乳液、水性色浆为主剂,增稠剂、干燥剂、消泡剂等为辅助剂配置水性油墨;利用平行板粘度计、旋转粘度计等检测油墨的粘度、软硬程度、流动值、拉丝性能、耐抗性等相关性能。结果随着丙烯酸树脂乳液相对于水性色浆比例的增大,粘度逐渐增加,丝头越短,油墨越硬,光泽度提高;随着聚氨酯乳液相对于水性色浆比例的增大,粘度逐渐减小,丝头越长,油墨先变软后变硬,光泽度降低;随着增稠剂加入量的增大,油墨粘度增大;随着催干剂的加入,油墨干燥时间缩短。结论丙酸烯树脂乳液与水性色浆的质量比为5∶1时为较优配方;聚氨酯树脂乳液与水性色浆的质量比为3∶1时为较优配方。The paper aims to study the effects of different formulations and proportions of raw materials on ink properties and printability. The water-based ink was prepared with polyurethane emulsion, acrylic resin emulsion and water-based color paste as main agent, thickener, desiccant and defoamer as auxiliary agent;parallel plate viscometer, rotating viscometer and other instruments were used to test ink viscosity, hardness, fluidity, wire-drawing property, resistance and other related properties. With the increase of the ratio of acrylic emulsion to water-based color paste, the viscosity increased gradually;the shorter the silk head, the harder the ink, and the higher the gloss;with the increase of the ratio of polyurethane emulsion to water-based color paste, the viscosity gradually decreased;the longer the silk head, the ink first became soft and then hard, and the lower the gloss. With the addition of thickener, ink viscosity increased. With the addition of drying agent, ink drying time was shortened. When the ratio of acrylic resin emulsion to water-based color paste is 5:1, it is a comparatively excellent formula. When the ratio of polyurethane resin emulsion to water color paste is 3:1, it is a comparatively excellent formula.
