Problems solved by technology

[0005] When the traditional cobalt black material is used in the preparation of ceramic ink, it has weak color development, impure color tone, and strong magnetic properties of the color material. When used on an inkjet machine, it will cause problems such as pulling lines and dripping ink, which affects the continuity of the inkjet printer. production, there are still big problems in the application of black pigments

Abstract

The invention discloses cobalt black pigment for ceramic ink. The cobalt black pigment is prepared from the following raw materials in percentage by weight: 35%-45% of Co3O4, 15%-20% of NiO, 8%-15% ofFe2O3, and 20%-30% of Cr2O3. Through massive test, an ideal pigment component formula scope and a pigment preparation method are obtained, and the obtained cobalt black pigment is plump in color, pure in color shaft and low in magnetic property.

Description

technical field [0001] The invention relates to the technical field of ceramic materials, in particular to a cobalt black material for ceramic ink and a preparation method thereof. Background technique [0002] Cobalt black material is favored by people for its solemn, elegant tone and dignified decorative effect. Although the price is high, it is still widely used in the field of architectural decoration, and the amount of coloring material is huge. [0003] 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 oil-based inks suitable for inkjet printing on ceramics. Since then, after more than ten years of development, inkjet printing technology has been widely used...
