Problems solved by technology

At present, about a dozen kinds of ceramic inks have been developed in China, among which blue has the strongest color development power, and yellow color development power is weak. Difficult to achieve, the whiteness of white ink is not high
The reason for these problems is that the existing ceramic inks have defects in conductivity, solid content, viscosity, color rendering, etc.

Embodiment Construction

[0014] A new type of ceramic ink for ceramic tile inkjet printing, which is composed of the following raw materials in parts by weight: 20% of composite perovskite-type inorganic pigment, 1% of alkylphenol polyoxyethylene ether, and the balance of solvent; wherein the composite calcium Titanium-type inorganic pigments are mixed with rare earth oxides, transition metal oxides, metal-organic framework materials, and calcium fluoride in a molar ratio of 1:1:0.01:0.001. After grinding and dispersing, they are calcined at high temperature, decarbonized, and ground. The obtained powder has a particle size of 0.01 μm.

[0015] The metal organic framework material is a porous material with a periodic network structure formed by self-assembly of Zn ions and 2-methylimidazole through coordination.

[0016] Wherein the solvent is 85% ethanol / water solution.

[0017] The high-temperature calcination process is as follows: the heating rate is 12°C / min, the temperature is 1350°C, and the s...

Abstract

The invention discloses a novel ceramic ink for inkjet printing of ceramic tiles. The novel ceramic ink for inkjet printing of the ceramic tiles is prepared from, by weight, 20-45% of composite perovskite type inorganic pigment, 1-2% of dispersant and the balance water, wherein the composite perovskite type inorganic pigment is a powdery material prepared by mixing rare earth oxide, transition metal oxide, a metal organic framework material and a fluxing agent according to the molar ratio of 1 to 1 to (0.01-0.05) to 0.001, performing grinding and dispersion and then performing high-temperature calcination, carbon removal and grinding, and the particle size of the powdery material is 0. 01-1 micron.

Description

technical field [0001] The invention relates to the technical field of ceramic inks, in particular to a novel ceramic ink used for tile inkjet printing and a preparation method thereof. Background technique [0002] With the development of the economy, consumers have higher and higher requirements for the quality of life. Ceramic tiles are an indispensable and important material in architectural decoration. They are a product that combines practicality and artistry. The pursuit of fashion is also more inclined to fashion and personalization. Ceramic printing technology is one of the important means of decoration to realize the diversification and individualization of ceramic decorative effects, and it is also an important driving force to promote the development of the modern ceramic industry. In particular, the emergence of inkjet printing technology has subverted the traditional printing technology and is the mainstream technology in the ceramic printing industry. [000...
