Problems solved by technology

However, based on the current research status at home and abroad, the currently published ceramic ink preparation methods still focus on the dispersion method, the sol-gel method and the inverse emulsion method, and the direct raw materials used are mostly metal oxides, and the above three production methods Among the methods, the sol-gel method is limited due to the complex manufacturing process, expensive raw materials, and unstable sol. The inverse emulsion method also has many technical problems to be solved due to the low solid phase content of the prepared ink. The problem of the dispersion method The reason is that the pigment particles are large, easy to agglomerate and will block or wear the printer nozzle

Abstract

The invention provides black ceramic ink and a preparation method thereof, and belongs to the technical field of ink preparation. The ceramic ink includes, by mass percentage, 25%-28% of a black pigment, 56%-60% of a solvent, 3%-6% of a dispersing agent BYK-2055, 3%-4.4% of organic bentonite, 0.3%-0.8% of a wetting agent Anti-terra-U, 5%-7% of a surfactant, and 0.4%-0.8% of an antifoaming agent. The black pigment is copper-chrome black doped with a small amount of aluminum oxide, and the mol ratio of the copper-chrome black to the aluminum oxide is 1 : 0.02-0.04. The ceramic ink takes the copper-chrome black as the pigment, so that the tinting strength of the ceramic ink can be enhanced through doping; through the blending of a dispersing system, excellent dispersing stability can be obtained; and through the controlling of formula composition and grinding parameters, the particle size and viscosity of the ink can accord with the requirements of an ink jet printer, so that a nozzle ofthe printer cannot be blocked.

Description

【Technical field】 [0001] The invention relates to the technical field of ink preparation, in particular to a black ceramic ink and a preparation method thereof. 【Background technique】 [0002] Inkjet printing technology is a non-contact digital printing technology successfully developed in the late 1970s. It sprays ink onto the surface of various media through the nozzles on the print head, realizing non-contact, high-speed, low-noise monochrome or color text or image printing. At the beginning of the 21st century, the American company Ferro developed an oil-based ink suitable for inkjet printing on ceramics. The corresponding patent application number in my country is 00818261.2. This started the widespread application of inkjet printing technology in the production of architectural ceramics. As a brand-new concept of ceramic decoration, printing technology for ceramic decoration can make full use of abundant computer data, introduce digital technology into traditional ar...
