Glass printing nanoscale ink and printing method

Abstract

The invention relates to the printing technical field, particularly to glass printing nanoscale ink and a printing method. The glass printing nanoscale ink comprises an inorganic colorant, a solvent and an inorganic binder; the inorganic binder can be molten or softened under the hearting treatment so as to fix the inorganic colorant on glass; inorganic colorant particles and the inorganic binder are uniformly dispersed in the solvent to form the suspension liquid allowing printing and flowing. The nanoscale ink based glass printing method comprises the steps of printing which comprises printing the glass nanoscale ink onto the surface of the glass through an inkjet printer according to a preset pattern; drying which comprises heating the glass so as to enable the organic solvent to be volatilized; fixation which comprises performing heating treatment on the glass to enable the inorganic binder to be molten or softened so as to fix the inorganic colorant on the glass. According to the glass printing nanoscale ink and the printing method, the size and position accuracy of the printing pattern on the surface of a glass plate can be improved.

Description

technical field [0001] The invention relates to the technical field of inkjet printing, in particular to a glass inkjet printing nano-scale ink and an inkjet method. 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. [0003] 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. [0004] 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 gla...

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
