Problems solved by technology

However, since the raw materials are dry powder materials, the particle size is generally 45-75 microns, the mixing and homogenization is not good, and the firing reaction is not sufficient, resulting in unstable product quality and light hair color.
Even if a crusher is used to crush the raw materials to a particle size of 13 microns before production, the cost will be greatly increased, and its quality and color development effect will not be ideal

Abstract

The invention discloses a preparation method of a ceramic pigment. The preparation method comprises the following steps: (1) detecting the content of metatitanic acid of metatitanic acid slurry, wherein the metatitanic acid content of the metatitanic acid slurry is 50-70%; (2) adding the following components in parts by weight: 120-240 parts of metatitanic acid slurry, 1-6 parts of chromium sesquioxide, 6-13 parts of antimony trichloride and 0-2 parts of auxiliary materials, and wetly stirring and homogenizing through stirring equipment; (3) adding water to regulate the slurry concentration tothe solid content of 50-70% so as to prepare mixed slurry; (4) pushing the mixed slurry into a rotary kiln for performing once-firing, and controlling the temperature to 1050-1250 DEG C; (5) enablingthe slurry out of a rotary cooler to enter grinding equipment so as to be ground, namely obtaining the ceramic pigment. The invention further discloses a ceramic pigment. According to the preparationmethod disclosed by the invention, the production efficiency can be improved, the production cost is reduced, and the pigment is stable in quality and high in coloring force.

Description

technical field [0001] The invention relates to the field of ceramics, in particular to a preparation method of a ceramic pigment; correspondingly, the invention also relates to a ceramic pigment. Background technique [0002] Ceramic pigments are indispensable decorative materials for modern ceramic products. Due to the constraints of raw materials and production processes, common ceramic pigments have large particle sizes, small contact areas, and poor fluidity, resulting in insufficient mixing and homogenization and incomplete reactions. , low production efficiency, light-colored and unstable products. For example, Chinese patent CN106278381A discloses a new type of ceramic pigment treatment process. Firstly, titanium dioxide, antimony dioxide and chromium dioxide are mixed and mixed thoroughly, fired in a kiln, cooled and pulverized, and finally ceramic pigments are obtained. However, since the raw material is a dry powder material, the particle size is generally 45-75 ...
