Embodiment 1

[0025] The preparation method of isooctanoic acid metal salt comprises the following steps:

[0026] (1) Using NaOH and isooctanoic acid as raw materials, the temperature is controlled at 80°C, and sodium isooctanoate is prepared through acid-base saponification;

[0027] (2) The sodium isooctanoic acid salt in step (1) is configured into a solution with a mass fraction of 20%, adding 20% ​​water-soluble metal salt solution and an appropriate amount of alkane solvent and mixing; the temperature is raised to 90° C., and reacted for 2 hours;

[0028] (3) After the reaction is completed, the liquid is extracted and separated, and the residual moisture is removed by distillation at a temperature of 120° C. to obtain the chromogenic organic isooctanoic acid metal salt;

[0029] Mix the leveling agent, the color-forming organic metal salt and the solvent according to the ratio in the table, stir evenly, and filter with a 1 micron filter element to obtain the white bleeding ink for c...

Abstract

The invention discloses a white stain-bleeding printing ink for ceramic ink-jet printing and a preparation method thereof. The printing ink is composed of following components in percentage by weight:0.05 to 0.2 wt.% of a leveling agent, 20 to 25 wt.% of chromophoric organic metal salts (by the weight of metal ions), and the balance being a solvent; wherein the chromophoric organic metal salts are mixed metal salts of organic cerium, organic zirconium, and organic aluminum. The printing ink has a white decorative effect, the species of ceramic stain-bleeding printing inks are enriched, and the decorative effect of ink-jet bleeding-stained bricks is further enhanced.

Description

technical field [0001] The invention relates to the technical field of ceramic inkjet printing, in particular to a white bleeding ink used for ceramic inkjet printing and a preparation method thereof. Background technique [0002] In recent years, with the comprehensive promotion and application of inkjet printing technology, which is known as the third decoration technology revolution in the ceramic industry, ceramic tile products have become more colorful, realistic, personalized and full of unlimited creativity. In order to apply this technology to the field of polished tiles, the technology of combining 3D bleeding ink with penetrability and inkjet printing technology came into being. In terms of texture, compared with ordinary polished tiles, since the 3D bleed ink will penetrate into the tile body at a depth of 0.6mm to 1.0mm, the three-dimensional effect of the design and color will be stronger, and the surface texture will be more delicate and realistic; at the same ...
