Preparation method of zirconium silicate coated pigment for high-coating-rate ceramic ink-jet printing
The invention discloses a preparation method of a zirconium silicate coated pigment for high-coating-rate ceramic ink-jet printing, which comprises the following steps of: preparing a coated pigment precursor by using a chemical coprecipitation method, pretreating the precursor, sequentially adding a silicon source and a zirconium source, carrying out ball milling, and carrying out after-treatmentto obtain the coated pigment. According to some examples of the invention, the coating rate of the zirconium silicate coated pigment can be significantly improved on the premise of meeting the use requirements of ink-jet printing, and by taking the cadmium selenide brilliant red pigment as an example, the coating rate can be improved from 7%-10% achieved by the conventional method to 11%-15%, andthe maximum particle size of the coated pigment is smaller than 1.8 [mu]m. The coated pigment can be directly used for ceramic ink-jet printing, the production cost of the coated pigment can be effectively reduced, and the pollution to the environment is greatly reduced.
本发明公开了一种高包裹率陶瓷喷墨打印用硅酸锆包裹色料的制备方法，包括使用化学共沉淀法制备得到包裹色料前驱体，对前驱体进行预处理后依次加入硅源和锆源进行球磨，后处理得到包裹色料。本发明的一些实例，在满足喷墨打印使用要求的前提下，可以显著提高硅酸锆包裹色料的包裹率，以硫硒化镉大红色料为例，包裹率可以由常规方法的7%～10%提高到11%～15%；包裹色料的最大粒径小于1.8μm，可以直接用于陶瓷喷墨打印；能有效降低包裹色料的生产成本，大幅减少对环境的污染。
