Problems solved by technology

The flexibility of current UV plastic screen printing inks is difficult to meet the requirements of PE and other plastic products, and the flexibility mainly depends on the composition of the formula: ①The lower the functionality, the better the flexibility, and the low-functionality monomer can reduce the crosslinking of the cured film Density, improve flexibility; ②Multiple acrylic monomers with longer flexible chain segments can provide suitable flexibility without affecting the curing rate

Abstract

The invention relates to the technical field of the UV (ultraviolet) ink, and in particular relates to a water-based UV plastic screen printing ink and a method for preparing the same. The water-based UV plastic screen printing ink provided by the invention is composed of the following raw materials in parts by weight: 25-40 parts of aliphatic urethane acrylate, 20-30 parts of UV cured acrylic emulsion, 10-20 parts of polyethyleneglycol diacrylate, 10-20 parts of ethylated trimethylolpropane triacrylate, 15-20 parts of pigment powder, 0.5-1 part of organic silicon defoamer, 1-5 parts of organic silicon flatting agent, 5-15 parts of absolute ethyl alcohol, 1-3 parts of photoinitiator, 0.4-2 parts of adhesion promoter and 4-10 parts of water. The water-based UV plastic screen printing ink greatly improves the flexibility of an ink layer and improves the properties of products, and is good in printing adaptability.

Description

technical field [0001] The invention relates to the technical field of UV inks, in particular to a water-based UV plastic screen printing ink and a preparation method thereof. Background technique [0002] UV ink is a kind of chemical reaction ink, which is the specific application of UV photocuring technology in the field of ink. UV ink is composed of resin with unsaturated functional groups, reactive diluent and initiator, pigment and auxiliary agent. It is printed on the base After being placed on the material, when irradiated by ultraviolet light, the initiator cracks to generate active free radicals or cations, which cause the polymerization of unsaturated functional groups to complete the drying process. As a new type of environmentally friendly ink, UV ink has the advantages of energy saving, no solvent emission, no pollution to the environment, high production efficiency, excellent printing performance, and low equipment investment. In the commercial supply market, ...
