Embodiment 1

[0037] Take 1 mol of soluble zirconium salt (calculated as zirconium), 1 mol of sodium silicate (calculated as silicon), 1 mol of sulfide, 1 mol of cadmium salt (calculated as cadmium), and 1 mol of selenium powder. Stir and mix, and the obtained precipitate is washed and added to a hydrothermal reaction kettle. Then add water to 75% of the volume of the hydrothermal reaction kettle, turn on magnetic stirring, discharge the material after treatment at 150 ° C for 4 hours, dry, add fluoride as a mineralizer, calcinate, and then pickle to obtain zirconium silicate wrapped sulfur selenide Cadmium pigment.

[0038] When preparing ink, take 25 parts by weight of zirconium silicate-wrapped cadmium sulfoselenide pigment, 10 parts of dispersant, and 75 parts of solvent, sand mill and filter to obtain zirconium silicate-wrapped cadmium sulfide selenide pigment ink. In this embodiment, the color of the ink is dark red.

[0039] In other embodiments, by adjusting the amount of selenium...

Embodiment 2

[0041] Take 1 mol of soluble zirconium salt (calculated as zirconium), 1 mol of sodium silicate (calculated as silicon), 0.5 mol of sulfide, and 0.5 mol of cadmium salt (calculated as cadmium), and prepare an appropriate amount of aqueous solution, and then stir and mix. After the obtained precipitate is washed, it is added to a hydrothermal reaction kettle. Then add water to 70% of the volume of the hydrothermal reaction kettle, turn on magnetic stirring, discharge at 145°C for 3.5 hours, dry, add fluoride as a mineralizer, calcinate, and pickle to obtain zirconium silicate-wrapped cadmium sulfide colorant.

[0042] When preparing the ink, take 50 parts by weight of zirconium silicate-wrapped cadmium sulfide pigment, 15 parts of dispersant, and 50 parts of water, sand mill and filter to obtain zirconium silicate-wrapped cadmium sulfide pigment ink. In this embodiment, the color of the ink is yellow.

Embodiment 3

[0044] Take 1mol of soluble zirconium salt (calculated as zirconium), 1mol of sodium silicate (calculated as silicon), 0.5mol of sulfide, 0.5mol of cadmium salt (calculated as cadmium), and 0.3mol of selenium powder, and make an appropriate amount of aqueous solution After that, it is stirred and mixed, and the obtained precipitate is washed and added to a hydrothermal reaction kettle. Then add water to 80% of the volume of the hydrothermal reaction kettle, turn on magnetic stirring, discharge the material after 4.5 hours of treatment at 155 ° C, dry, add fluoride as a mineralizer, calcinate, and then pickle to obtain zirconium silicate-wrapped sulfur selenium Cadmium Chloride Pigment.

[0045] When preparing ink, take 80 parts by weight of zirconium silicate-wrapped cadmium sulfoselenide pigment, 20 parts of dispersant, and 92 parts of water, sand mill and filter to obtain zirconium silicate-wrapped cadmium sulfide selenide pigment ink. In this embodiment, the color of the i...

Abstract

A preparing method of ceramic inkjet ink is disclosed. The method is characterized in that the ink is prepared from an inclusion type cadmium sulfoselenide colourant or an inclusion type cadmium sulfide colourant; and the inclusion type cadmium sulfoselenide colourant is one or more of a zirconium silicate inclusion type cadmium sulfoselenide colourant, a silicon dioxide inclusion type cadmium sulfoselenide colourant and a zirconium dioxide inclusion type cadmium sulfoselenide colourant. The inclusion type cadmium sulfide colourant is one or more of a zirconium silicate inclusion type cadmium sulfide colourant, a silicon dioxide inclusion type cadmium sulfide colourant and a zirconium dioxide inclusion type cadmium sulfide colourant. Compared with the prior art, the ink is prepared by using the inclusion type cadmium sulfoselenide colourant creatively, the technical constraint that application of the zirconium silicate inclusion type cadmium sulfoselenide colourant for preparation of inkjet ink is difficult is overcome at a stroke, the color of the inkjet ink can be configured as a series of colors from yellow to orange to crimson, and the inkjet ink is rich in color, various in choice, suitable for various ceramic products and dark in color development.

Description

technical field [0001] The invention relates to the technical field of ceramic printing and dyeing, in particular to a preparation method of ceramic inkjet ink. Background technique [0002] In recent years, the construction industry has begun to use inkjet printing technology on a large scale to replace traditional screen printing. Inkjet inks are generally divided into two types: water-based inks and oil-based inks. The main components of inks are: colorants, dispersants, solvents (or water), and various additives. The common colors of ink are red, yellow, reddish brown, yellowish brown, cobalt blue, black and so on. The existing red pigment is mainly chrome tin red, which can only be used in the production of tiles, and is not suitable for most other types of ceramic tiles, and the color of chrome tin red is relatively light. The yellow pigment is praseodymium yellow, and the hair color is also lighter. Contents of the invention [0003] Aiming at the problems existi...
