Novel ceramic ink-jet ink and production process thereof

Abstract

The invention relates to a novel ceramic ink-jet ink and a production process thereof. The novel ceramic ink-jet ink is prepared from the following components by percentage by weight: 38%-42% of water-soluble metal salt, 7%-9% of a complexing agent, 14%-25% of a surfactant, 29%-34% of a water-soluble organic solvent, 1%-4% of an auxiliary material and 0.05%-0.1% of a pH value regulator. The novel ceramic ink-jet ink has strong stability, the influences caused by other substances such as solvents are small, the solubility range is relatively wide, the liquidity and the color development property are stable, and the pH value is neutral, so that the corrosion damage caused to a spray head is avoided; the novel ceramic ink-jet ink can directly infiltrate by 5mm-10mm into a tile blank, infiltration color development is formed, and the infiltration effect is good; the color development effect of metal salt is rich and stable, and after novel ceramic ink-jet ink infiltrates into the surface of a tile, the color is relatively fine and bright; the novel ceramic ink-jet ink can be subjected to 1260 DEG C high-temperature sintering with the tile blank, can meet the high-temperature sintering requirements of the tile blank and can reach Moh's hardness 6-7, and the hardness is obviously improved; lots of water grinding fineness processes are not required, the machining process is relatively environmentally friendly, and the energy consumption is relatively low.

Description

technical field [0001] The invention relates to the technical field of architectural ceramic decoration, in particular to a novel ceramic ink-jet ink and a production process thereof. Background technique [0002] Traditional ceramic inkjet is a kind of ceramic inkjet ink made of ceramic pigment powder into multicolor. The ceramic inkjet ink is ejected as small ink droplets from nozzles with a diameter of tens of microns at a speed of thousands of drops per second. The technique of depositing on the green body, glaze or other carrier can be single color or multi-color combination. Inkjet printing technology has been widely used, and its application mainly has the following two aspects: ceramic product decoration and ceramic forming; ceramic product decoration is to make ceramic colorant into multi-color ink, and print it on the ceramic surface through a computer-controlled printer For decoration, its advantage lies in the use of computer resources to realize the change of d...

Problems solved by technology

[0003] Traditional ceramic ink is usually composed of ceramic powder, solvent, dispersant, binder, surfactant and auxiliary materials. Ceramic powder is the core of the ink, and its particle size is required to be less than 1 micron, which requires ball milling and high energy consumption. The solubility of ceramic powder is small, the surface tension of the ink is unstable, and the viscosity changes greatly. Usually, there are problems that the particles are easy to agglomerate and have low stability, and are greatly affected by other substances such as solvents. Spray on the surface of the tiles, due to the poor permeability, you can still feel the pattern texture protruding on the surface of the tiles, which affects the fidelity; in addition, ceramic products generally need to be fired at a high temperature of more than 1,000 degrees, and the ink on the surface is usually affected. High temperature affects the color effect, it is difficult to meet the requirements of high temperature firing, and the hardness of fired tiles is low
