Preparation method of yellow zirconium silicate pigment for ink-jet printing and product prepared by same

Abstract

The invention relates to a preparation method of a yellow zirconium silicate pigment for ink-jet printing and a product prepared by the same. The preparation method comprises the following steps of: successively introducing gas-phase SiO2 into a ZrOCl2.8H2O solution according to the molar ratio, and adding a praseodymium chloride solution and PEG (polyethylene glycol) 1000 for reacting to obtain a colloid; regulating the pH value of the colloid to be equal to 7, and then, adding LiF powder; and calcining at 900-1000 DEG C to obtain a yellow pigment for ink-jet printing, wherein the granularity of the yellow pigment is less than 1mu m, and the service temperature of the yellow pigment is higher than 1300 DEG C. The product prepared by the method provided by the invention has the characteristics of uniform chromaticity, high suspension property and coloring power, good high-temperature stability, vivid color development, good decorative effect and the like, meets the requirement for ink-jet printing of ink, and has wide application prospects in the fields of production and the like of architectural ceramics.

Description

technical field [0001] The invention belongs to the field of inorganic non-metallic materials, and in particular relates to a method for preparing yellow zirconium silicate pigment for inkjet printing and a product prepared therefrom Background technique [0002] The traditional decoration method of architectural ceramics mostly adopts screen printing technology. The requirement of this technology for the particle size of the color material is to pass through a 325-mesh sieve (that is, the particle size of the color material is less than 45 μm). The color material used in this decoration method is mostly solid phase. It can be synthesized by ball milling method and meet the requirement (particle size<45μm). However, with the advancement of technology and people's demand for high-performance products, there is now an inkjet printing technology for the decoration of ceramic products. Inkjet printing technology is a non-contact printing technology successfully developed in t...

Problems solved by technology

However, this new decoration technology has very high requirements on the color material, and the particle size of the color material is required to be below 1 μm. If the color material prepared by the solid phase method is ball milled, although the particle size of the color material can meet the requirements (particle size < 1 μm ), but after ball milling (particle size <1μm), the color will become very light, and the decorative effect cannot be achieved
