Ink solvent for glass inkjet printing

Abstract

The invention relates to the technical field of jet printing, and discloses an ink solvent for glass inkjet printing, which is used for dissolving and / or swelling pigment. The ink solvent is preparedfrom resin, fuel and silicate, wherein the resin is used for immobilizing pigment onto glass; the fuel is used for carrying the pigment; the silicate is heated to be melted and softened so as to position ink on the glass; the solution which has fluidity and can be sprayed is formed. The ink solvent has the advantages that under the heating condition, the silicate molecules in the ink and the silicon dioxide or silicate molecules at the glass surface mutually disperse and permeate via the molecule thermal movement; in the heating process, the fuel for carrying the pigment can generate flash burn and produce heat, the temperature at the ink layer and glass surface is further increased, the molecule thermal movement and mutual dispersion between the ink layer and the glass surface are promoted, the positioning and fixing of jet printing patterns are accelerated, the size deviation of the jet printing patterns on the surface of a glass plate is effectively decreased, and the size and position accuracy of the patterns on the surface of the glass plate is obviously improved.

Description

technical field [0001] The invention relates to the technical field of inkjet printing, in particular to a glass inkjet printing ink solvent. Background technique [0002] Using glass as a decorative plate can be widely seen in daily life, especially in the interior decoration industry and advertising industry. It generally makes various exquisite patterns on the surface of the glass plate. However, there are many ways to make patterns on the surface of the glass plate. For example, the pattern can be generated by decals on the glass plate, but the adhesive tape layer used for the decals is easy to fall off and be damaged, resulting in poor durability and weather resistance of the product. In order to make up for the above defects, most of the traditional methods of printing patterns on the surface of glass plates are through screen printing or pad printing technology. Although this process can effectively fix the patterns on the glass surface, they all need to be made in ad...

AI Technical Summary

Problems solved by technology

However, in actual production, the surface of the glass plate has no pores, and its smoothness is much higher than that of the ceramic plate. During the high-speed inkjet printing process of the nozzle, the ink is difficult to absorb on the glass surface and slips, and the pattern is not easy to accurately position. As a result, the printed pattern is deviated and the pattern size accuracy and position accuracy on the glass plate are low. In this regard, the roughness of the surface of the ceramic plate is conducive to the absorption of ink and the precise positioning of the pattern.

The above-mentioned problems have shown that after the glass spray-painting process scheme of the prior art draws lessons from the ceramic spray-paint process scheme, there are still defects
