A kind of toughened glass ink for inkjet printing and preparation method thereof

Abstract

The invention discloses a tempered glass ink for ink-jet printing and a preparation method thereof. The ink is prepared from low-temperature frit, inorganic pigments, a dispersant, resin, a flatting agent and a solvent. The tempered glass ink for ink-jet printing has good stability, favorable ink-jet printing performance, low viscosity which ranges from 10.0 to 40.0mPa.s and can be regulated, uniform particle size distribution, the surface tension of 25 to 35mN / m, an average particle size of 200 to 400 nm and a maximum particle size of less than 1 micrometers, and can be stored for a long time. The ink prepared by the preparation method disclosed by the invention has low sintering temperature and can be well combined with glass. The sintered surface is strongly resistant to acid, alkaline and ultraviolet radiation.

Description

technical field [0001] The invention relates to a special ink, in particular to a tempered glass ink for inkjet printing and a preparation method thereof. Background technique [0002] Colored glazed glass is to print the ink made of inorganic glaze on the glass surface, then dry, temper or thermally process, and permanently sinter the glaze on the glass surface to obtain a wear-resistant, acid and alkali resistant glass. Decorative glass products. Colored glazed glass is usually decorated with inorganic glazes on the glass surface by screen printing or roller printing. After drying and heat treatment, a permanent and firm glaze layer is finally formed on the glass surface. However, there are many disadvantages in the method of screen printing or roller printing: 1) the color and pattern of the texture are single, and it is difficult to make complex pattern products; The cost is high and does not meet the trend requirements of energy conservation and environmental protecti...
