Problems solved by technology

At present, there are very few types of glass inkjet printing inks on the market, for example, red ink, which cannot meet the needs of the market; the existing glass inkjet printing inks are not environmentally friendly, and contain heavy metals, such as lead, cadmium and other chemical elements. As a result, its scope of application is narrow; and the acid and alkali resistance and scratch resistance of the existing glass inkjet printing inks cannot meet the industry requirements, and technology updates are pending

Abstract

The invention discloses a preparation method of environment-friendly high-performance digital ink-jet red ink, and relates to the technical field of glass painting, the preparation method comprises the following steps: (1) preparing basic color glaze powder; (2) preparing red wrapping powder; (3) preparing a primary finished product of the digital ink-jet red ink; and (4) carrying out negative pressure filtration to obtain a digital ink-jet red ink finished product, and then packaging. The ink does not contain heavy metals, and meets environmental protection requirements; the red ink is subjected to ink-jet printing on the surface of glass, then is sintered and tempered at the high temperature of 650-750 DEG C, is completely dissolved in the glass and is integrated with the glass, and the color is bright and stable; the acid resistance and the alkali resistance of the red ink completely reach the industrial standard, and the scratch resistance reaches the sixth level of the industrial standard.

Description

technical field [0001] The invention relates to the technical field of glass inkjet printing, in particular to a preparation method of an environment-friendly high-performance digital inkjet red ink. Background technique [0002] Tempered glass is a prestressed glass. The impact strength and bending strength of tempered glass with the same thickness are 3 to 5 times that of ordinary glass. Although the performance of tempered glass has advantages compared with ordinary glass, its decorative effect is poor. Digital inkjet printing is a technology of non-contact printing of digital patterns in a computer on a glass surface through a nozzle. Digital inkjet printing equipment can print ink on the surface of glass, and then sinter and temper the printed glass at a high temperature of 650-750 °C, so that the ink is fused with the surface of the glass and fixed on the surface of the glass. At present, there are very few types of glass inkjet printing inks on the market, such as ...
