Problems solved by technology

However, these solvent-based glass screen printing inks contain a large amount of organic solvents, and during use, the organic solvents volatilize into the atmosphere, which not only endangers human health, but also causes serious environmental pollution
In addition, solvent-based glass screen printing inks need to be baked and cured at high temperatures, and the baking temperature is mostly between 180 and 220°C, which consumes a lot of energy and is not conducive to resource conservation.

Abstract

The invention provides a water-borne glass silk screen printing ink, which is composed of the following components by weight: 30-55wt% of acrylic resin, 4-12wt% of amino resin, 10-35wt% of pigment, 3-10wt% of filler, 0.5-5wt% of a cosolvent, 0.5-3wt% of an additive and 15-40wt% of water. The invention also provides a preparation method of the water-borne glass silk screen printing ink. The water-borne glass silk screen printing ink has the characteristics of few volatile matter, strong adhesion, boiling resistance, good acid and alkali resistance, and good yellowing and solvent resistance. Atthe same time, a screen printed coating film has high gloss and no solvent residue, is environmentally friendly, and is harmless to the human body. The preparation method of the water-borne glass silkscreen printing ink is simple and is easy to operate.

Description

technical field [0001] The invention belongs to the technical field of water-based ink, and in particular relates to a water-based glass screen printing ink, and also relates to a preparation method of the water-based glass screen printing ink. Background technique [0002] With the continuous improvement of human living standards and quality of life, countries all over the world have increasingly strict requirements for environmental protection. Glass screen printing ink is one of the main consumables in the printing industry. The printing industry and printed matter users have put forward higher and stricter requirements for the environmental performance of printed matter, and then put forward higher requirements for the environmental performance of printed glass screen printing ink. Traditional solvent-based glass screen printing inks contain a high volatile solvent mass fraction, resulting in high VOC emissions, which not only cause environmental, atmospheric, and ecolog...
