Description

A kind of UV curing ink used for digital product touch screen glass printing and preparation method thereof

technical field

The invention relates to an ink and a preparation method thereof, in particular to a UV curable ink used for digital product touch screen glass printing and a preparation method thereof.

Background technique

Screen printing is to stretch silk fabrics, synthetic fabrics or wire mesh on the screen frame, and adopts the method of manual engraving paint film or photochemical plate-making to make screen printing forme. Modern screen printing technology is to use photosensitive materials to make screen printing plates by means of photographic plate making (so that the screen holes of the graphic part on the screen printing plate are through holes, and the screen holes of the non-graphic part are blocked. Living) oil paintings, prints, posters, business cards, binding covers, commodity packaging, commodity signs, printing and dyeing textiles, touch screen glass and metal and other flat carriers. The ink is a two-liquid reactive screen printing ink that is beneficial to the environment. It has superior printing stability, excellent adhesion and resistance, which are essential for touch screen glass printing. The cured coating film has good adhesion and water resistance. Chemical resistance, but also has high surface hardness and wear resistance.
