Abstract

A bismuth oxide-based ink for glass digital inkjet printing and a preparation method thereof, is characterized in that it is composed of a bismuth oxide-based colorant, an organic solvent and an acrylic resin, wherein the mass percentages of the bismuth oxide-based colorant, the organic solvent, and the acrylic resin are respectively 55‑65%, 25‑35%, 5‑20%, the sum of each component is 100%. Bismuth oxide-based pigments consist of bismuth oxide amorphous silica, boron oxide, lithium oxide, aluminum oxide, zirconium oxide and industrial pigments. The organic solvent consists of the main solvent (1‑(2‑methoxy‑1‑methylethoxy) isopropanol, 1‑ethoxy‑2‑propanol, 1‑methoxy‑2‑propanol, cyclo Hexanone or a mixture thereof), dispersant (diethylene glycol butyl ether), surfactant (1,2-propylene glycol diacetate) and light stabilizer (HS-508). The preparation process of the ink consists of the steps of grinding the color material, mixing the color material with solvent and acrylic resin, and filtering. The ink of the invention has good dispersibility, fast volatilization speed, good stability and good inkjet printing performance.

Description

technical field [0001] The invention belongs to the technical field of glass digital inkjet printing, in particular to a bismuth oxide-based ink for glass digital inkjet printing and a preparation method thereof. technical background [0002] Inkjet printing is to print ink onto the medium through the nozzle to realize the printing of text and images. Inkjet printing technology has been widely used in printing media such as paper, textiles, plastic products, leather goods, wood boards, etc. for a long time, but it is a new development in recent years to apply it to the field of glass decoration. In recent years, the global glass inkjet printing technology has developed rapidly. More and more domestic glass decoration enterprises have begun to introduce inkjet printing equipment and glass ink (the raw material for preparing ink contains glass materials), and then launched inkjet printing glass products. [0003] Glass digital inkjet printing technology has special requiremen...
