Ultraviolet light curing offset printing ink and preparation method thereof

Abstract

The invention relates to an ultraviolet light curing offset printing ink and a preparation method thereof. The ultraviolet light curing offset printing ink is made of 25.0-50.0% of polyfunctional polyester acrylic resin or polyfunctional chlorinated polyester acrylate, 0.0-15.0% of epoxy acrylate oligopolymer, 0.0-20.0% of polyfunctional urethane acrylate, 0.0-15.0% of difunctional or polyfunctional acrylic monomer, 0.0-20.0% of grinding-type resin, 2.0-10.0% of polyether acrylate modified by nano silicon dioxide, 0.0-5.0% of adhesion promoter, 3.0-5.0% of photoinitiator, 0.1-2.0% of polymerization inhibitor, 0.0-10.0% of filler, 16.0-55.0% of paint or dye and 0.2-5.0% of accessory ingredient. The prepared offset printing ink has high transparency as well as good adhesive attraction and flexility, and can be widely applied to packages printing industry and the printing of various transfer paper.

Description

technical field [0001] The invention relates to the field of printing inks mainly made of artificial resins, and relates to printing inks containing photocurable resins. In particular, it relates to a photocurable ink for offset printing and a preparation method thereof. Background technique [0002] Since the German Bayer company developed the first generation of ultraviolet curing (UV curing) coatings in 1967, UV curing technology has developed rapidly in the world and has rapidly spread in electronics, printing, construction, decoration, medicine, machinery, chemical industry and so on. Promotion and application in automobile and other industries. UV curable inks have fast curing, no pollution, high coating quality, high hardness, scratch resistance, and corrosion resistance. They conform to the development direction of modern coatings and inks and have attracted people's attention. At present, UV-curable printing inks, as a large category of UV-curable materials, have ...

AI Technical Summary

Problems solved by technology

However, there is no mention of UV offset printing inks, especially for UV-curable inks used on transfer paper. Due to its high requirements and standards, it has been difficult to break through the technology for a long time.

[0004] Description: Transfer paper is a new type of environmentally friendly printing material. It replaces the original cardboard with film. There is no plastic film on its surface. This material is environmentally friendly and saves the amount of plastic used, and it can be degraded and recycled after the packaging is used up. , will not affect the environment, but the strength of this kind of paper is relatively lower, and the ink printed on it is also higher.
