Embodiment 1-5

[0032] The composition formula of the colored glaze mixed ink for inkjet printing of ceramics provided in Examples 1-5 is shown in Table 1 below.

[0033] Table 1

[0034]

Embodiment 1

[0035]The pigment used in Example 1 is praseodymium yellow, and the prepared ink is yellow in color. The semiconductor oxide is a mixture of tin oxide and zinc oxide, and the mass ratio of tin oxide and zinc oxide is 8:2. The mass percentage of the chemical composition of the glaze powder is: silicon dioxide: 45% to 50%; aluminum oxide 18% to 22%, ferric oxide: ≤0.2%; titanium dioxide: ≤0.3%; calcium oxide 8% to 12% ;Magnesia 4%~5%; Potassium oxide: 2%~5%; Sodium oxide: 3%~5%; Barium oxide: 2%~4%; Zirconia: 1%~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 the Segel formula and the common mineral or frit raw materials used in ceramic production. Therefore, only the chemical composition requirements of the glaze powder are given here. For raw materials from different origins or frits with different chemical compone...

Embodiment 2

[0052] 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 semiconductor oxide is selected as a mixture of titanium oxide and tin oxide, and the mass ratio of the two is 1:2.

[0053] 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 be used as the raw material of the color material. .

Abstract

The invention provides anti-static colored glaze mixed ink for ceramic ink-jet printing and a preparation method thereof, belonging to the technical field of ceramic tile decoration. The ink provided by the invention comprises the following components in percentage by weight: 25%-30% of pigment, 10%-15% of glaze powder, 1%-5% of magnesium carbonate, 45%-55% of diethylene glycol, 1%-3% of dispersing agent, 0.5%-2% of binding agent, 0.5%-2% of surfactant and 5%-10% of semiconductor oxide. A printed layer formed by the ink provided by the invention has a good anti-static effect, and an anti-static ceramic product produced by utilizing the ink is suitable for special engineering purposes.

Description

technical field [0001] The invention relates to a ceramic tile decoration technology, in particular to an ink for inkjet printing of ceramics, more specifically, to an antistatic colored glaze mixed ink for inkjet printing of ceramics 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 new concept of ceramic decoration, color printing technology for cerami...
