[0011] A screen printing ink, comprising the following raw materials in parts by weight: 50 parts of polyurethane diacrylate, 30 parts of hexanediol diacrylate, 8 parts of benzophenone, 20 parts of coloring agent, 2 parts of reinforcing agent, and antistatic agent 2 parts, 2 parts of defoamer, 2 parts of fluorescent pigment, 3 parts of polypropylene resin mixed with barium sulfate

Embodiment 2

[0013] A screen printing ink, comprising the following raw materials in parts by weight: 40 parts of polyurethane diacrylate, 20 parts of hexanediol diacrylate, 5 parts of benzophenone, 10 parts of coloring agent, 1 part of reinforcing agent, and an antistatic agent 1 part, 13 parts of defoamer, 1 part of fluorescent pigment, 1 part of polypropylene resin mixed with barium sulfate.

Embodiment 3

[0015] A screen printing ink, comprising the following raw materials in parts by weight: 65 parts of polyurethane diacrylate, 50 parts of hexanediol diacrylate, 10 parts of benzophenone, 30 parts of coloring agent, 3 parts of reinforcing agent, and antistatic agent 3 parts, 3 parts of defoamer, 3 parts of fluorescent pigment, 5 parts of polypropylene resin mixed with barium sulfate.

[0016] The screen printing ink produced by the formula of the invention has high fixation fastness, and at the same time, by adding fluorescent pigments to the screen printing ink, it has the function of anti-counterfeiting.

Abstract

The invention relates to the screen printing industry, in particular to a screen printing ink. The screen printing ink comprises the following raw materials in parts by weight: 40-65 parts of polyurethane diacrylate, 20-50 parts of hexanediol diacrylate, 5-10 parts of a photoinitiator, 10-30 parts of a coloring agent, 1-3 parts of an enhancer, 1-3 parts of a destaticizer, 0-3 parts of a foam killer, 0-3 parts of a fluorescent pigment, and 1-5 parts of polypropylene resin mixed with barium sulfate. The screen printing ink produced according to the formula has high color fastness. Meanwhile, as the fluorescent pigment is added into the screen printing ink, an anti-counterfeiting role can be played.

Description

technical field [0001] The invention relates to the screen printing industry, in particular to a screen printing ink. Background technique [0002] The traditional screen printing ink is a kind of loose slurry with good thixotropy. When the ink is at rest, its fluidity is poor. Once it is subjected to external force, the fluidity of the ink increases sharply. This feature enables the ink to pass through the mesh of the printing plate smoothly during scraping printing, and quickly level off on the substrate to form the desired image. In this way, the ink film will not leave traces of the screen after drying, and will not cause the printed image to overflow and expand. However, the fixation fastness of this traditional screen printing ink is low. Contents of the invention [0003] The purpose of the present invention is to provide a screen printing ink with high fixation fastness. [0004] In order to realize the foregoing invention object, the present invention provides ...
