Description
Technical Field
The invention belongs to the technical field of ceramic ink and inkjet printing, and particularly relates to rapid-permeation inkjet printing ceramic ink and a preparation method thereof.
Background
After the innovation of screen printing and roller printing, the decoration technology in the building ceramic industry has entered the full digital inkjet printing era, and the inkjet printing technology is therefore called the third revolution of tile printing technology. Inkjet printing technology has many incomparable advantages over screen printing or roller printing: if it only needs to pass through the computer regulation just can reach various individualized requirements in the very short time, and its printing fineness does not have the difference with high definition picture, and it also can not receive the restriction of ceramic tile specification simultaneously, and these advantages make the ink jet printing technique more accord with the development trend of ceramic tile, also consequently can widely apply.
At present, ceramic ink used in ceramic ink-jet printing technology adopts a dispersion method, in which components such as organic solvent, ceramic pigment, dispersant and additive are mixed and then ground at high speed to finally obtain stable suspension. However, for fully polished glazed or antique tile products, the use of oily solvents and oily dispersants in the ceramic inks can lead to the so-called "ink-glaze separation" phenomenon, reducing the goodness of the fully polished or antique tile products. For example, in invention CN107828282a, a method for preparing high-stability yellow ink is disclosed, which uses paraffin oil as a solvent, and when the amount of ink is large, the ink can form an organic oil film on the glaze of a tile (such as a full-polished glaze or an antique tile) product, which can hinder the effective spreading of an aqueous glaze slurry (such as an aqueous protective glaze), thereby causing a series of glaze problems. According to statistics, the product degradation caused by the 'glaze-ink separation' problem accounts for 70% of the unqualified products. The reasons for such problems are still that the solvent system of the ceramic ink makes the ceramic ink difficult to penetrate into the ceramic glaze layer, and the water in the oily system (such as oily solvent and the like) floating on the glaze surface and the aqueous protective glaze repel each other. For this reason, many ceramic ink manufacturers have begun to improve the problems by adjusting the formulation, but the effect is not obvious, and serious glaze surface problems still occur especially under the condition of large ink amount. Therefore, there is an urgent need to develop a ceramic ink which can rapidly permeate on a ceramic glaze and is suitable for ink-jet printing.
