Abstract

UV cured gravure ink and a preparation method thereof relate to UV gravure ink printed adopting engraved intaglio printing and a preparation method thereof in the printing industry and aim at solving the problems of long drying period, easy plate drying, roll drying and poor transitive property in the existing engraved gravure ink. The ink comprises the following components according to mass percent: oligopolymer (30-65 percent), light trigger (1.5-6 percent), pigment (8-15 percent), filler (15-40 percent), diluter (3-15 percent), and addition agent (0.2-5 percent); the preparation method includes the steps of: pre-dispersing 95 percent of the oligopolymer, the pigment and the filler, rolling the components on an ink rolling machine to satisfy specified fineness requirement; putting the rolled components into a stirring bucket so as to be stirred at uniform speed, and adding the remaining 5 percent of the oligopolymer, and the light trigger and the addition agent for uniform mixing; and the diluter is used for adjusting the viscosity of oil. The invention is applicable to engraved intaglio printing.

Description

technical field

[0001] The invention relates to a UV gravure printing ink used in the printing industry for engraving gravure printing and a preparation method thereof. Background technique

[0002] Ink drying is a process in which the ink changes from a liquid state to a solid ink film with a certain strength, and post-press drying is an important printability index of the ink. Existing inks used in engraving and gravure printing generally adopt three drying methods: osmotic drying, volatile drying, and oxidative polymerization drying, and the drying cycle (generally takes 48 hours) is relatively long; And oxidative polymerization, the ink viscosity value increases, the ink thickens, gelatinized dry plate, dry roll, poor transferability and other phenomena occur from time to time; and the pollution caused by VOC emissions is not conducive to environmental protection. Contents of the invention

[0003] The purpose of the present invention is to solve the problems of long ...
