Abstract

The invention belongs to the technical field of ceramic pigments, and in particular relates to a black pigment for ceramic inkjet printing and its preparation method and application; the parts by weight of each raw material in the black pigment are: 17-35 parts of pre-fired material, Co 3 o 4 25-36 parts for NiO, 30-45 parts for NiO, MnO 2 0-5 parts, Al 2 o 3 0‑4 parts, SrCO 3 0-3 copies, Bi 2 o 3 0‑2 parts and MoO 3 Is 0.5-1.5 part; Wherein, described calcined material is Cr 2 o 3 and Fe 2 o 3 Mixed and fired materials. Through the combination of the above-mentioned raw materials, the black pigment can solve the problems of unstable color development and glaze defects (such as color difference, yin and yang, pinholes, and white spots) after the existing black pigment is made into ink. Effectively improve the color development of black ceramic inks and reduce glaze defects.

Description

technical field [0001] The invention relates to the technical field of ceramic coloring materials, in particular to a black coloring material for inkjet printing of ceramics and its preparation method and application. Background technique [0002] After less than ten years of development, ceramic inkjet printing technology has basically replaced traditional printing technology. In recent years, tile products with gray, white and black patterns have become popular. This design style has been widely used in fully glazed, antique tiles and ceramic rock slab products, which has led to an increase in the use of black ink. [0003] Existing black pigments, such as a Cu-Mn-Fe-Cr cobalt-free black ceramic pigment and its preparation method disclosed in application number CN201310213944.2, and a kind of tannery sludge disclosed in application number CN202010541428.2 The method for preparing black cobalt-based ceramic pigments is to use raw materials cobalt oxide, chromium oxide, nic...
