Abstract

The invention discloses screen printing ink. The screen printing ink comprises the following components by weight percent: 35-36% of a reactive oligomer, 15-50% of an active monomer, 3-7% of a photoinitiator, 10-30% of a coloring agent, 1-5% of additives and 2-5% of a surfactant, microcrystalline wax, silicide or a mixture of the surfactant, the microcrystalline wax, and the silicide. The screen printing ink has surface tension equal to or less than that of the printing surfaces and has a good printing effect.

Description

A kind of screen printing ink

Technical field

The present invention relates to a kind of screen printing ink.

Background technology

The surface tension relationship of ink is to the transfer performance of ink and the stability of trace on the face of undertaking the printing of.This relation, when light plane materiel material, particularly frosting print, seems more outstanding.Such as, when the surface tension that the surface tension of ink is greater than the face of undertaking the printing of is more, trace can shrink, and even occurs the aperture of fish-eye shaped; If undertake the printing of, the surface tension of face and ink is close, and when the surface tension of half tone is greater than the surface tension in the face of undertaking the printing of, printing there will be network blocking phenomenon.

Summary of the invention

For overcoming the shortcomings and deficiencies of above-mentioned prior art, the invention provides a kind of screen printing ink.

The technical solution adopted in the present invention is:

A kind of screen printing ink, comprises each component and mass percent is: reactive oligopolymer 35 ~ 60%, reactive monomer 15 ~ 50%, light trigger 3 ~ 7%, tinting material 10 ~ 30%, additive 1 ~ 5%; Also comprise the tensio-active agent of 2 ~ 5%, microcrystalline wax, silicide or its mixture;

Described reactive oligopolymer is epoxy double methacrylate, polyester double methacrylate, urethane double methacrylate, or its mixture;

Described reactive monomer is tripropylene glycol diacrylate or hexanediyl ester;

Two kinds of mixtures in described light trigger benzophenone, thioxanthone and st-yrax ethers;

Described additive comprises quick dry agent, toughener, static eliminating agent.

Described light trigger, also containing organic amine.

Screen printing ink of the present invention, is added with tensio-active agent, microcrystalline wax, silicide etc. and is adjusted, make the surface tension of ink be equal to or less than table two tension force in the face of undertaking the printing of, obtain good printing effect.
