Problems solved by technology

However, these inks have great disadvantages: the temperature required for high-temperature sintering inks is usually above 600°C, which consumes a lot of energy; self-drying solvent-based inks have a large amount of VOC emissions when drying, polluting the environment, and the drying time is relatively long , You need a lot of space to put these wet prints, even after the surface is dry, the ink is easy to be wiped off, and it takes a week to dry completely; two-component heat-curing glass ink needs to be cured at 160°C for 30 minutes , the energy consumption is also very large, and the space occupied is also large; water-based glass ink is relatively environmentally friendly, but the curing temperature is about 160 ° C, and the curing time is about 30 minutes, or even longer

Abstract

The invention discloses an LED-UV photocurable screen printing halogen-free glass ink. The LED-UV photocurable screen printing halogen-free glass ink is prepared from the following raw materials in percentage by mass: 30-70% of multi-functional group polyester acrylate, 10-30% of urethane acrylate, 10-40% of functional acrylate monomer, 3-10% of photoinitiator, 1-3% of defoamer, 0.1-1.5% of flatting agent, 1-5% of adhesion promoter, 3-8% of organic pigment and 4-50% of inorganic pigment. The invention also discloses a preparation method of the ink. The preparation method comprises the steps of blending, grinding and dispersing, and filtering. Compared with the existing inks, the LED-UV photocurable screen printing halogen-free glass ink is energy-saving, environment-friendly, and high in performance; the operation area needed during printing is relatively small.

Description

technical field [0001] The invention relates to a screen printing halogen-free glass ink cured by LED-UV light. Background technique [0002] Printing on glass has always been based on silk screen printing, and the inks used are usually high-temperature sintered inks, self-drying solvent-based inks and two-component heat-curing inks. In recent years, many documents and patents have proposed environmentally friendly Water-based glass ink. However, these inks have great disadvantages: the temperature required for high-temperature sintering inks is usually above 600°C, which consumes a lot of energy; self-drying solvent-based inks have a large amount of VOC emissions when drying, polluting the environment, and the drying time is relatively long , You need a lot of space to put these wet prints, even after the surface is dry, the ink is easy to be wiped off, and it takes a week to dry completely; two-component heat-curing glass ink needs to be cured at 160°C for 30 minutes , t...
