Abstract

The invention discloses ceramic ink with good stability, and a preparation method of the ceramic ink. The ceramic ink is prepared from the following raw materials in parts by weight: 9-17 parts of polytetrafluoroethylene, 1-5 parts of pigment, 5-12 parts of isopropyl palmitate, 3-7 parts of 2,6-dihydroxypyridine-4-carboxylic acid, 2-6 parts of dimethyl carbonate, 11-19 parts of titanium dioxide and 40-48 parts of 50% ethanol solution. The preparation method comprises the steps of mixing the polytetrafluoroethylene with an isopropyl palmitate solution, stirring while heating, and then dropwise adding the dimethyl carbonate while stirring so as to obtain a mixture A; grinding the pigment and titanium dioxide, then adding a 2,6-dihydroxypyridine-4-carboxylic acid solution into the ground material, and stirring to obtain a mixture B; mixing the mixture A with the mixture B, and finely grinding until the particle size of the mixture is less than 1.5 microns; then, carrying out ultrasonic treatment for 45min to obtain the ceramic ink. The ceramic ink prepared by the method has good high temperature resistance, and can completely bear the temperature of pottery firing; the chromogenic rate of the ink is greatly increased, and the color generation is stable; furthermore, the ceramic ink does not easily precipitate, and is good in stability.

Description

Technical field [0001] The invention relates to the technical field of inks, in particular to a ceramic ink with good stability and a preparation method thereof. Background technique [0002] With the development of market economy and computer technology, the existing traditional ceramic decoration methods can no longer meet market needs. The introduction of modern computer technology is an inevitable trend in the future development of ceramic product design. At present, inkjet printing technology, a new process for moldless molding, is becoming a research hotspot worldwide, and various ceramic inks supporting it have also appeared. Inkjet printing is a highly potential decoration technology. The method is to make colorants into multi-color ink for ceramic surface decoration, and print the multi-color ink directly on the ceramic surface for decoration through a computer-controlled printer. Ceramic products generally need to be fired at a high temperature of more than one thousa...
