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

Abstract

The invention relates to a blue zirconium silicate pigment for spray ink printing and a preparation method of blue zirconium silicate pigment. The blue pigment with a particle size of less than 1 mu m and an operating temperature of above 1,300 DEG C is prepared by using gas-phase silicon dioxide (SiO2), zirconium oxychloride 8 hydrogen oxide (ZrOCl2.8H2O), polyethylene glycol (PEG) 1000, ammonia water, lithium fluoride (LiF) and ammonium metavanadate (NH4VO3) powder as raw materials. The molar percentage ratio of Si4 to Zr2 is 1.2 to 1; the molar percentage ratio of Li to Si4 is 0.3 to 1; the molar percentage ratio of V5 to Si4 is 0.0075 to 1; and the molar percentage ratio of PEG to SiO2 is (0.0015-0.0045) to 1. The blue zirconium silicate pigment has the characteristics of uniform chromaticity, high suspension property, high tinting strength, good high-temperature stability, bright colour, good decoration effect and the like, meets a requirement of ink for spray ink printing and has wide application prospects in production of architectural ceramics.

Description

technical field [0001] The invention belongs to the field of inorganic non-metallic materials, and in particular relates to a blue zirconium silicate pigment for inkjet printing and a preparation method thereof. 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 the late 1970s. digita...
