Problems solved by technology

These reports are all ceramic inks prepared based on pigments, but ceramic inks prepared based on ceramic glazes, especially environmentally friendly water-based glaze inks, are rarely reported.
For glazes, its preparation does not need to be fired between 900-1400°C like pigments. It contains a large amount of plastic material, which makes it easy to cause great thickening and thixotropy after ultra-fine, especially in the water phase. Phenomenon, making it difficult to realize the preparation of low viscosity and high solid content water-based glaze ink
[0004] The construction technology of ceramic glazes is usually through glaze spraying, spraying glaze, screen printing or roller printing, etc. These processes have high pollution, low efficiency, and waste resources to a large extent. It is to decorate the concave and convex surface of ceramics

preparation example Construction

[0036] The preparation method of the above-mentioned environment-friendly ceramic ink-jet printing glaze ink comprises the following steps:

[0037] 1) Prepare water-based dispersion: add resin to the mixed solvent of ethylene glycol, propylene glycol and water, stir to dissolve, add dispersant, water reducer and defoamer respectively, and stir evenly;

[0038] 2) Prepare the glaze slurry, add the glaze into the aqueous dispersion, pre-disperse with a high-speed disperser to fully wet the glaze, and then transfer it to a sand mill for grinding, and control the average particle size of the glaze particles at 200 ~400 nm, the maximum particle size is less than 1 μm, to obtain glaze slurry;

[0039]3) Add leveling agent, pH regulator, viscosity regulator, preservative and remaining solvent to the glaze slurry, stir evenly, and filter with a 1 μm filter membrane to obtain glaze ink for ceramic inkjet printing.

Abstract

The present invention discloses an eco-friendly glaze ink for ceramic jet printing and preparation method thereof, the ink comprises, based on the mass percentage, 30-50% of ceramic glaze, 15-25% of organic solvent, 4-10% of dispersant, 2-5% of water reducing agent, 2-5% of resin, 0.3-0.6% of defoaming agent, 0.1-0.2% of leveling agent, 0.1-0.2% of pH modulators, 2-5% of viscosity regulator, 0.1-0.3% of preservative and the balance for water. The eco-friendly glaze ink for ceramic jet printing provided by the invention has good stability for long-term storage and good performance for ink-jet printing, with low ink viscosity and uniform distribution of particle diameter, wherein the regulable viscosity is between 10 and 40.0mPa.s, and the surface tension is between 32 and 40mN / m, and the pH value is between 7.5 and 8.5, and the average particle diameter is between 200 and 400nm, and the maximum particle diameter is less than 1 Mum.

Description

technical field [0001] The invention belongs to the technical field of ceramic inkjet, and in particular relates to an environment-friendly glaze ink for ceramic inkjet printing and a preparation method thereof. Background technique [0002] Ceramic inkjet technology is a non-contact digital printing technology. It is ink made of ceramic color glaze powder, and small ink droplets are sprayed from a nozzle with a diameter of tens of microns onto the surface of architectural ceramics, and fired. The decorative technique of post-color rendering, the shape and geometric size of the decorative pattern are controlled by the computer. Compared with the traditional decoration method of ceramic tiles, ceramic inkjet technology has the advantages of low energy consumption, low pollution, high efficiency, especially the ability to decorate concave and convex surfaces, so ceramic inkjet technology has become a mainstream technology.
