Abstract

The invention relates to a water-based yellow ceramic ink for inkjet printing and a preparation method thereof. The preparation method comprises: crushing quartz, zirconia, praseodymium oxide, cerium oxide and a mineralizer and mixing them evenly, and then mixing the obtained mixture After pressing and molding, place it in a crucible with a cover, cover the crucible and put it in an electric furnace for calcination. The fired product after firing is ball milled, washed, suction filtered and dried in sequence to obtain ceramic color material; ceramic color material The material is mixed with water and dispersant and ball milled to form a suspension, and then the suspension is ultrasonically dispersed to form a water-based yellow ceramic ink. In the present invention, try to add a large amount of praseodymium oxide and cerium oxide to carry out praseodymium-cerium co-doping, so that cerium can be doped into the zirconium silicate lattice and generate zirconia cerium oxide, so that cerium can be used as a chromogenic agent. It is added into the pigment praseodymium oxide to solve the problem of high synthesis cost in the traditional praseodymium yellow material due to the large amount of praseodymium oxide added, and at the same time it can also enhance the color development effect of ceramic pigments and ceramic inks.

Description

technical field [0001] The invention relates to the technical field of ceramic ink, in particular to a water-based yellow ceramic ink for inkjet printing and a preparation method thereof. Background technique [0002] Ceramic inkjet printing technology is a non-contact, high-speed, low-noise printing technology that uses computer-controlled ceramic ink nozzles to decorate the surface of ceramic bodies based on the existing inkjet printing technology. Compared with traditional printing technology, Ceramic inkjet printing technology has the advantages of low printing cost, hygienic working environment, convenient conversion and production, and less waste of color and glaze materials. It is a ceramic decoration technology with great application value. [0003] Yellow ceramic ink, one of the three primary colors, is widely used in the decoration of ceramic products. The preparation of the yellow ceramic ink includes two parts: ceramic pigment preparation and ink preparation. A...
