Embodiment 1-5

[0031] The composition formula of the colored glaze mixed type antibacterial ink for ceramic inkjet printing provided by Examples 1-5 is shown in Table 1 below.

[0032] Table 1

[0033]

Embodiment 1

[0034]The pigment used in Example 1 is praseodymium yellow, and the antibacterial agent containing silver ions is a mixture of silver nitrate and calcium phosphate, wherein the mass fraction of calcium phosphate is 8%, and the rest is silver nitrate. In this example, the mass percentages of the chemical components of the calcium-based glaze powder are: silicon dioxide: 45% to 50%; aluminum oxide 18% to 22%, ferric oxide: ≤0.2%; titanium dioxide: ≤0.3%; Calcium oxide 10%~12%; Magnesium oxide 4%~5%; Potassium oxide: 1%~3%; Sodium oxide: 3%~5%; Barium oxide: 2%~4%; Zinc oxide: 1%~2% %; zirconia: 1% to 2%; loss on ignition: ≤1%; water: ≤0.5%. Through the mass percentages of the above chemical components, those skilled in the art can calculate the dosage of the formula through the chemical analysis results of minerals or frit materials commonly used in ceramic production, so only the chemical components of calcium-based glaze powder are given here. According to requirements, those...

Embodiment 2

[0055] For the formula, see the mass ratio of each component given in Table 1. In this example, the pigments used are cobalt blue and spinel-based black pigments mixed at a mass ratio of 1:2. The ratio of the two can be matched according to the ink color required in actual use. , And if necessary, other pigments can also be added, such as: praseodymium yellow, red brown, orange and so on. The antibacterial agent containing silver ions is a mixture of silver nitrate and calcium phosphate, wherein the mass fraction of calcium phosphate is 12%, and the rest is silver nitrate.

[0056] In this example, the preparation method is basically the same as that in Example 1, except that the raw materials of the colorant used in this example are pre-calcined before use. Specifically: the cobalt blue and spinel black pigments are calcined at a temperature of 700-850 ° C, and the particle size reaches 325 mesh. The standard analysis sieve residue ≤ 0.05%, and the water content ≤ 0.5% can b...

Abstract

The invention provides a ceramic ink-jet printing colored glaze mixed type antibacterial ink and a preparation method thereof, and belongs to the ceramic brick decoration technology. The ceramic ink-jet printing colored glaze mixed type antibacterial ink provided by the invention comprises the components by the mass percentage: 28%-35% of a coloring material, 11.5%-17% of a calcium-based glaze powder, 0.5%-3% of an antibacterial agent containing silver ions, 1%-5% of magnesium carbonate, 45%-55% of diethylene glycol, 1-3% of a dispersant, 0.5%-2% of a bonding agent, and 0.5%-2% of a surface active agent. An ink-jet printing layer formed after ink-jet printing of the ink on a ceramic brick blank has good antibacterial effect after sintering, and moreover, the printing layer is resistant to wear and lasting in antibacterial effect, and is especially suitable for bottom surface decoration of public space having urgent antibacterial requirements.

Description

technical field [0001] The invention relates to a ceramic tile decoration technology, in particular to an ink for ceramic ink-jet printing, and more specifically, to a color-glazed antibacterial ink for ceramic ink-jet printing and a preparation method thereof. Background technique [0002] Bacteria and mold, as pathogenic bacteria, are very harmful to humans, animals and plants, affecting people's health and even life-threatening, and bringing significant economic losses. Therefore, the research on antibacterial materials and their products has attracted people's attention day by day, and the demand for antibacterial products will constitute a huge market. Ceramic tiles have the characteristics of high strength, long service life, and rich decorative effects. They have always been the most commonly used building materials, and they are also one of the most frequently encountered materials. Therefore, if ceramic tile products can be made to have an antibacterial function, i...
