Problems solved by technology

[0003] And because the ceramic inkjet ink is a ceramic ink made into a solution from the ceramic powder to be formed, the configured ceramic ink is directly printed on the surface of the building ceramics by the printer, and then sintered, due to the special characteristics of the ceramic inkjet ink The preparation and use methods are different from ceramic coatings, and both belong to two different technical fields, which makes it difficult to directly apply the technology in ceramic coatings to ceramic inkjet inks. Therefore, in view of the existing problems in the prior art, it is urgent to provide a Special white ceramic inkjet ink technology is particularly important

Embodiment 1

[0054]This embodiment provides a special white water-based ceramic inkjet ink, the ceramic pigment is a sol prepared by a sol-gel method between a precursor of zirconia and a precursor of silicon oxide, wherein the sol is 0:1 ≤The number of moles of silica: the number of moles of zirconia≤1:1. In this embodiment, the sol contains silica sol, and the molar ratio of silica to zirconia in the sol is less than or equal to 1:1. Other The composition is basically the same as that of ordinary water-based ceramic inkjet ink.

[0055] In this embodiment, the precursor of the above-mentioned zirconia is zirconium oxychloride or ammonium zirconia. Of course, the precursor of zirconia can also be other substances, as long as it can be prepared by sol-gel method to obtain zirconia sol. Yes; the precursor of the above-mentioned silicon oxide is one or more of tetraethoxy silicon, tetramethoxy silicon and water glass, wherein the modulus of water glass is equal to or greater than 2, and of c...

Embodiment 2

[0058] A kind of special white water-based ceramic ink-jet ink of the present embodiment, except ceramic pigment, other components are deionized water, water-based dispersant, surfactant, water-soluble organic solvent and ink auxiliary agent, this special white water-based ceramic ink-jet ink is made of Composition of the following weight percentages:

[0059] Deionized water 20~55%

[0060] Sol 35~60%

[0061] Water-based dispersant and surfactant 2~10%

[0062] Water-soluble organic solvent 2-10%

[0063] Ink additives 2~6%

[0064] Wherein, the weight of the sol is calculated by the dry weight of zirconia and silicon oxide after the ink is fired, and the molar ratio of zirconia and silicon oxide is 1:1.

[0065] Wherein, the weight of deionized water, the dry weight of the sol after ink burning, the weight of water-based dispersant and surface activity, the quality of water-soluble organic solvent and the weight of ink additives are the total weight, and the weight perc...

Embodiment 3

[0081] The main technical solutions of this embodiment are basically the same as those of Embodiment 1 or 2, and the features not explained in this embodiment are explained in Embodiment 1 or Embodiment 2, and will not be repeated here. A kind of ultra-white water-based ceramic inkjet ink of this embodiment also contains silane coupling agent, when preparing ultra-white water-based ceramic ink-jet ink, add coupling agent when adding water-soluble organic solvent, surfactant, coupling agent mainly There are water-soluble silane coupling agents and titanate coupling agents, specifically aminopropyl triethoxy silicon, aminopropyl trimethoxy silicon, glycidyl triethoxy silicon, glycidyl trimethoxysilane etc.

Abstract

The invention relates to extra-white aqueous ceramic ink-jet ink. Ceramic pigment is sol prepared from a zirconium oxide precursor and a silicon oxide precursor through a sol-gel method. The white ceramic pigment is prepared by the sol-gel method, has small particle size and good sphericity, solves the technical problem of long time and high energy consumption when the traditional ceramic ink-jet ink is ground, can keep active groups through the sol-gel reaction, can be sintered at a low temperature, and overcomes the technological difficulty that zirconium oxide pigment in the prior art is required to be sintered and adhered tightly at 1500 DEG C. The preparation method of the extra-white aqueous ceramic ink-jet ink comprises the steps of sol preparation and grinding, the preparation method is simple, the prepared extra-white aqueous ceramic ink-jet ink has the advantages of high whiteness, good ink-jetting effect, suitability for high-precision ink-jet printing cartridge and the like.

Description

technical field [0001] The invention relates to the technical field of ceramic inkjet, in particular to an ultra-white water-based ceramic inkjet ink and a preparation method thereof. Background technique [0002] Ceramic inkjet technology is a technology that applies inkjet printing technology to the surface of ceramics for decoration. It is to make ceramic ink from the ceramic powder to be formed, and use the printer to directly print the configured ceramic ink to the surface of architectural ceramics. This is followed by sintering, in which the shape and geometry of the shaped body are controlled by a computer. At present, the ceramic inks used by most domestic ceramic enterprises are mainly ceramic inks produced by several foreign companies such as Spanish Esmalglass~itaca, and American Ferro. Domestic ceramic inks are mainly ceramic inks launched by Mingchao Technology Development Co., Ltd. in 2010. Inkjet ink. Ceramic inkjet inks at home and abroad are mainly blue, b...
