Abstract

The invention discloses rapid-curing screen printing ink, and relates to environment-friendly energy-saving LED (Light Emitting Diode)-UV (Ultraviolet) screen printing ink. The rapid-curing screen printing ink contains no toxic matters, cannot generate ozone, is odorless and contains no benzene and aromatic organic solvents, a photo-resist film is not easy to burn and deform, the temperature of acontactor is lower than 70 DEG C, drying is fast, curing and crosslinking can be realized within 2 to 3 seconds, and a printing product is high in fastness and has no radiation light. The rapid-curingscreen printing ink is prepared from the following components: 51 to 58 parts of methacrylate prepolymer, 15 to 19 parts of reaction monomer, 12 to 15 parts of pigment, 1 to 4 parts of dispersing agent, 0 to 5 parts of filler, 7 to 10 parts of photocatalyst and 0 to 1 part of polymerization inhibitor. The rapid-curing screen printing ink is cured and dried through a UV-LED light source.

Description

technical field [0001] The invention relates to the field of ink industry, in particular to fast curing silk screen printing ink. Background technique [0002] Ink is a uniform mixture composed of colored bodies (such as pigments, dyes, etc.), linking materials, filling (filling) materials, additional materials, etc.; it can be printed and dried on the printed body; it is colored and has a certain Fluid paste-like adhesive body. Ink is used to form graphic information in the printing process, so ink plays a very important role in printing. It directly determines the tone, color, and clarity of the image on the printed matter. Due to the wide range of uses of screen printing and low investment, screen printing is used for substrates that are difficult to print by other printing methods, so the screen printing process has developed rapidly in the past ten years. [0003] The process of screen printing for many years: plate making on the screen roll, the ink is printed and im...
