Embodiment 1-10

[0033] The component formulations of the color-glazed mixed-type luminous materials for ceramic inkjet printing provided in Examples 1-10 are shown in Table 1 below.

[0034] Table 1

[0035]

Embodiment 1

[0036] The color material selected in Example 1 is praseodymium yellow, and the long afterglow luminescent material is selected as aluminate-based long afterglow luminescent material SrAl 2 o 4 : Eu, Dy (green fluorescence), the color of the prepared ink is yellow, and the fluorescence lasts for ≥4 hours after the environment changes from light to dark. In this embodiment, the mass percentages of the chemical components of the glaze powder are: silicon dioxide: 45% to 50%; aluminum oxide 18% to 22%, ferric oxide: ≤0.2%; titanium dioxide: ≤0.3%; calcium oxide 8%~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 the Segel formula and the common mineral or frit raw materials used in ceramic pro...

Embodiment 2

[0053] 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 long afterglow luminescent material is selected as the aluminate-based long afterglow luminescent material "CaAl 2 o 4 :Eu,Nd" (blue fluorescence) and "Sr 4 al 14 o 25 :Eu,Dy” (blue fluorescence) is prepared by mixing at a mass ratio of 1:3.

[0054] 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 ana...

Abstract

The invention provides a colored glaze mixed type noctilucent ink for ceramic ink-jet printing and a preparation method thereof, and belongs to the ceramic brick decoration technology. The colored glaze mixed type noctilucent ink for ceramic ink-jet printing includes the components by the mass percentage: 28%-35% of a coloring material; 10%-15% of a glaze powder; 2%-5% of a long afterglow luminescent material; 1%-5% of magnesium carbonate; 45%-55% of diglycol; 1-3% of a dispersant; 0.5%-2% of a binding agent; and 0.5%-2% of a surface active agent. An ink-jet printing layer formed after ink-jet printing on a ceramic brick blank by using the ink can be directly fired, and the formed printing layer has a noctilucent effect, can be applied for use in instruction and marking, is more safe, can replace staircase indicator lights, can save energy, and also can present more abundant display effect.

Description

technical field [0001] The invention relates to a ceramic tile decoration technology, in particular to an ink for ceramic inkjet printing, more specifically, to a color glaze mixed luminous ink for ceramic inkjet printing 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 ceramic decoration ...
