preparation example Construction

[0030] In a first aspect, the present invention provides a method for preparing a vanadium-zirconium blue ceramic pigment, comprising the steps of:

[0031] S1. Dissolving zirconium oxychloride, zirconium sulfate, and vanadyl sulfate in water to form solution A;

[0032] S2. dissolving sodium hydroxide, potassium hydroxide and ammonia water in water to form solution B;

[0033] S3. dissolving the dispersant in water to form a solution C;

[0034] S4. Add solution A and solution B dropwise to solution C at the same time, keep stirring, and control the pH value of the solution during the dropping process to be 8.5-9.5;

[0035] S5. Dropping water glass solution and dilute sulfuric acid solution respectively to form co-precipitation, filtering, drying and calcining to obtain vanadium-zirconium blue ceramic pigment.

[0036] In the present invention, zirconium oxychloride and zirconium sulfate are creatively used as the source of zirconium, vanadyl sulfate is used as the source ...

Abstract

The invention discloses a vanadium-zirconium blue ceramic pigment, a vanadium-zirconium blue ceramic ink and a preparation method of the vanadium-zirconium blue ceramic pigment. The preparation methodincludes the steps of dissolving zirconium oxychloride, zirconium sulfate and vanadyl sulfate in water to form a solution A; dissolving sodium hydroxide, potassium hydroxide and ammonium hydroxide inwater to form a solution B; dissolving a dispersing agent in water to form a solution C; dropwise adding the solution A and the solution B into the solution C simultaneously and performing continuousstirring, wherein the pH value of the solution is controlled to be 8.5-9.5 in the dropwise adding process; dripping a water glass solution and a dilute sulfuric acid solution into the solution, and after coprecipitation is formed, performing filtration, washing, drying and calcination to obtain the vanadium-zirconium blue ceramic pigment. The coprecipitation method is adopted for preparing the vanadium-zirconium blue ceramic pigment, the obtained particles are very fine and evenly distributed, the color is bright and deeper, the tinting strength is high, the stability is high, the product cost is low, the product quality is excellent, the cost is much lower than that of mature products in the market, and the use standard of high-grade printing ceramic inks can be met.

Description

technical field [0001] The invention relates to the technical field of ceramic pigments, in particular to a vanadium-zirconium blue ceramic pigment, a vanadium-zirconium blue ceramic ink and a preparation method thereof. Background technique [0002] At present, ceramic decoration has begun to use ceramic inkjet printing decoration technology, which makes ceramic ink into ceramic ink, and prints it directly onto the ceramic surface through a computer-controlled printer for decoration. Its advantage is that it can overcome the limitations of high technical requirements for operators, low production efficiency, and poor pattern reproducibility of hand-painted decoration technology; it can make up for the shortcomings of screen printing, rubber roller printing technology, etc. And the pattern is flexible, without the advantages of molds, etc., to meet the characteristic needs of individual production. [0003] The preparation of ceramic ink with stable performance is one of th...
