目的 研究开发曲面喷墨打印水性喷墨墨水的制备，用喷墨打印的方式对不规则曲面制品进行图文装饰。方法 通过选择树脂种类，调整色浆和水的含量以及添加其他助剂，制备出具有较好印刷适性（如不堵塞喷头，粘度适宜，表面张力好）的水性喷墨墨水。结果 制备出的水性软性喷墨墨水和硬性喷墨墨水，软性墨水的颗粒度为0.2～0.6 μm，粘度控制在5～6 mPa?s，表面张力为27～29 mN/m；硬性墨水的颗粒度为0.3～0.6 μm，粘度控制在7～8 mPa?s，表面张力为25～27 mN/m。结论 通过对树脂种类、色浆的选择，水的含量及其他助剂的确定，制得了一款环保的曲面喷墨打印水性墨水。

The work aims to study and develop the preparation of water-based ink-jet ink for curved-surface ink-jet printing, and decorate the irregular curved-surface products with graphics and text by means of ink-jet printing. Through the selection of resin type, adjustment of the content of color paste and water and addition of other additives, the water-based ink-jet ink with better printability (such as no blockage of the nozzle, proper viscosity and good surface tension) was prepared. For the prepared water-based soft ink-jet ink and hard ink-jet ink, the particle size of the soft ink was 0.2～0.6 μm, the viscosity was controlled at 5～6 mPa?s, and the surface tension was 27～29 mN/m; while the particle size of the hard ink was 0.3～0.6 μm, the viscosity was controlled at 7～8 mPa?s, and the surface tension was 25～27 mN/m. Through the selection of resin type and color paste, and the determination of water content and other additives, an environmentally friendly water-based ink for curved-surface ink-jet printing is prepared.
