Problems solved by technology

At present, the inkjet printing ceramic inks that have been published for decorative ceramics have been disclosed to have photocatalytic properties, but their photocatalytic properties still need to be improved; in addition, the colorants of ceramic inks are mainly organic solvent-soluble Composed of metal salts, after the ceramic ink is printed and baked, some colorants undergo chemical changes under high temperature, which leads to darkening or even no color development of the colorants, especially red

Abstract

The invention belongs to the technical field of ceramic ink, and specifically relates to red ceramic ink. The ceramic ink is mainly prepared from the following materials, by weight: 18-23 parts of a pigment, 14-18 parts of glaze powder, 4-8 parts of modified molecular sieve, 2-5 parts of magnesium carbonate, 40-45 parts of a solvent, 1-3 parts of phenolic resin pyrrolidone, 1.5-2.5 parts of phenolic resin, 2-5 parts of a surfactant and 0.3-0.8 part of an antifoaming agent; and the modified molecular sieve is prepared by combining the characteristics of the ceramic ink. The ceramic ink has photocatalysis performance, and can effectively degrade the organic pollutants on ceramic surfaces and decompose the organic harmful gas in air after being printed on ceramic bricks; in addition, the color brightness of red can be enhanced; and as the ceramic ink is simple in preparation method, the ceramic ink is easy to produce.

Description

【Technical Field】 [0001] The invention belongs to the technical field of ceramic ink, and specifically relates to a red ceramic ink and a preparation method thereof. 【Background technique】 [0002] Inkjet printing technology is a molding technology with great potential application value. The key to achieving inkjet printing is ceramic ink. Because once the ceramic ink quality is not good enough, the printer will not work normally. Among them, the quality of ceramic ink only needs to be reflected in the dispersion stability of the ceramic pigment in the system, and only the ceramic ink with high stability can match the printer and work normally. At present, the inkjet printing ceramic ink used for the production of decorative ceramics has been published to have photocatalytic performance, but its photocatalytic performance still needs to be improved; in addition, the colorant of the ceramic ink is mainly composed of organic solvent soluble It is composed of metal salt. After th...
