Problems solved by technology

In addition to praseodymium yellow, the traditional yellow pigment is praseodymium yellow, which is deeper than praseodymium yellow, but package yellow also has the disadvantage that the smaller it is ground, the lighter the hair color, and it is more serious than praseodymium yellow, so ordinary package yellow is used to grind It is not feasible to make the particle size smaller to achieve the purpose of developing a darker color than praseodymium yellow

Abstract

The invention discloses a preparation method of a yellow wrapper for ink-jet printing ceramic ink. The preparation method includes the following process steps that 1), mixed liquid is formed after 5-10 parts of cadmium sulfide and 60-65 parts of zirconium acetate are dissolved in water respectively, and a sodium sulfide water solution is prepared from 3-4 parts of sodium sulfide; 2), the mixed liquid and the sodium sulfide water solution are stirred and mixed, and precipitates are obtained; 3), the precipitates are washed with hot water and ground to be 100-150 mesh, then the precipitates and15-20 parts of water glass are stirred and mixed until gel is formed, the gel is dried and then mixed with 5-8 parts of mineralizer, and finally calcination is carried out for 10-12 min at the high temperature of 900-950 DEG C. The traditional production process of the yellow wrapper is improved, by adjusting the additive amounts of the raw material components and reducing the firing temperature,the prepared yellow wrapper can achieve the fineness of 100-150 mesh and the yellow developing effect that the yellow wrapper is darker than a praseodymium yellow pigment by one time or above, and thecolor developing effect is stable.

Description

technical field [0001] The invention relates to the field of ceramics, in particular to a ceramic pigment. Background technique [0002] In the past, the materials used by ceramic factories to color ceramics were pigments, but now ceramic inks have become the mainstream coloring materials through printer printing, and yellow coloring materials are used in large quantities and become an indispensable coloring material. The main problem of the current yellow pigment is light color after it is made into ink, and in many cases it cannot meet the application requirements of ceramic factories. The light color is mainly because the yellow pigment is made of traditional praseodymium yellow material through grinding to make the particle size smaller, and as the particle size becomes smaller, the hair color will become lighter. So it was inevitable to develop a deeper yellow pigment. In addition to praseodymium yellow, the traditional yellow pigment is praseodymium yellow, which is ...
