Abstract

The invention provides single-component waterborne glass ink. The single-component waterborne glass ink comprises the following main raw materials in parts by weight: 25-55% of water-soluble acrylic resin, 1-15% of waterborne inorganic nano-silicate resin, 10-35% of waterborne amino resin, 0.3-1% of dispersant, 0.1-1.5% of waterborne organosilicone defoaming agent, 0.1-1% of leveling agent, 0.1-1% of fumed silica, 0-2% of silane coupling agent, 0.5-1.8% of polyethylene wax, 4-30% of water-based pigment and 3-15% of deionized water. Accordingly, the invention also provides a preparation method of the single-component waterborne glass ink. By adopting the preparation method disclosed by the invention, the hardness, high-temperature resistance, solvent resistance, weather resistance and boiling resistance of the glass ink can be greatly improved so as to meet the requirements of the ink for the glass panel of a mobile phone.

Description

technical field [0001] The invention relates to the technical field of inks, in particular to a one-component water-based glass ink and a preparation method thereof. Background technique [0002] Glass screen printing inks, solvent-based one-component glass inks, and two-component inks on the market all contain a large amount of organic solvents, such as ketones and benzenes. A large amount of organic solvents will be volatilized and discharged into the air during printing, which will pollute the environment, which is not conducive to environmental protection and the health of operators. The two-component ink also causes a lot of waste. [0003] Moreover, the water-based single-component baking glass inks commonly used on the market for mobile phone glass panels are generally made of epoxy-modified water-based acrylic resins and water-based amino resins or water-based polyurethane resins. of. Due to the limitation of the characteristics of the water-based organic resin its...
