Abstract

The invention discloses UV-LED (Ultraviolet-Light Emitting Diode) cured flexographic printing ink, which is prepared from the following components in percentage by mass: 30 to 40 percent of prepolymer, 3 to 7 percent of pigment, 5 to 7 percent of photoinitiator, 1 to 3 percent of additive and 35 to 45 percent of hexanediol diacrylate, wherein the sum of the percentages (by mass) of the componentsis 100 percent. The prepolymer is hyperbranched polyester acrylate, the pigment is yellow ink or carmine ink; the photoinitiator is any one or a composition of at least two of 819 (phenylbis(2,4,6-trimethylbenzoyl)phosphine oxide), TPO (2,4,6-Trimethylbenzoyl-diphenylphosphine Oxide) and ITX (2-Isopropylthioxanthone); the additive is a mixture of a flatting agent and a dispersing agent; the flatting agent and the dispersing agent are polyurethane RM2020 and CF-10 respectively; further, the mass mixing ratio of the flatting agent to the dispersing agent is 1 to 1. The UV-LED cured flexographicprinting ink which is provided by the invention is low in viscosity, high in curing velocity and high in color intensity.

Description

technical field

[0001] The invention belongs to the technical field of printing ink, relates to a UV-LED cured flexo printing ink, and also relates to a preparation method of the flexo printing ink. Background technique

[0002] At present, the issue of green environmental protection has become an issue of great concern to people, and the promotion and application of environmentally friendly packaging and printing methods is an inevitable direction for the development of packaging and printing. Flexo printing is widely used in packaging and labeling industries due to its unique structure and printing principles. The traditional use of UV light sources to cure flexo printing inks takes a long time to cure, has low efficiency, and has defects such as short life, high power consumption, thermal deformation of printing materials, and heavy metal pollution. Contents of the invention

[0003] The purpose of the present invention is to provide a UV-LED cured flexo printing ink, ...
