Abstract

The invention discloses a novel preparation method of ceramic printing ink containing carbon black. The preparation method comprises the steps of carbon black modification, preparation of modified carbon black sol, preparation of silica sol, preparation of zirconia sol, preparation of zirconium silicate containing carbon black precursor, preparation of zirconium silicate containing carbon black powder, and the preparation of zirconium silicate containing carbon black ceramic printing ink. The ceramic ink containing carbon black utilizes zirconium silicate containing carbon black nanoparticlesinstead of cobalt, chromium and other heavy metal elements in the prior art, being environmentally friendly without pollution. The cheap carbon black is used to replace the expensive cobaltous oxide in the existing black ceramic pigment material, greatly reducing the cost of black ceramic ink. The ceramic ink containing carbon black is in deep and pure color, and has good high temperature stability. The average particle size D50 of zirconium silicate containing carbon black nanoparticles in ceramic inkcontaining carbon black is less than 300nm, meeting the requirement of almost all ceramic nozzles for the fineness of ink particles in the market.

Description

technical field [0001] The invention relates to the technical field of ceramic inks, in particular to a novel carbon black-wrapped ceramic printing ink and a preparation method thereof. Background technique [0002] With the development of science and technology and people's relentless pursuit of beauty, traditional ceramic decoration methods can no longer meet the needs of the market. The emergence of ceramic inkjet printing technology has combined ceramic decoration with modern computer control methods, bringing the development of ceramic decoration industry into a new era. Domestic and foreign scientific research institutions and large ceramic decoration companies have carried out research and development on this inkjet printing technology. As we all know, ceramic products need to be fired at a high temperature of about 1200 degrees. Therefore, ceramic printing inks suitable for inkjet printing technology also need to withstand corresponding high temperatures. Pigments t...
