Abstract

The invention discloses UV matte environment-friendly offset printing ink and a preparation method thereof. The UV matte environment-friendly offset printing ink is composed of the following components in percentage by mass: 15-28% of an acrylic emulsion, 11-21% of polyester acrylic resin, 1-7% of polymethylurea resin, 1-7% of self-extinction polyurethane resin, 5-13% of a reactive diluent, 4-7% of a photoinitiator, 8-26% of a pigment and filler and 1-7% of auxiliaries, with the balance being deionized water, summing to 100%. According to the invention, the resin with an extinction effect andthe self-extinction polyurethane resin are compounded, and under the action of the auxiliaries, the glossiness of the UV offset printing ink is effectively reduced, so the prepared ink has an excellent matte effect; and the ink also has the advantages of good wear resistance, low irritation, good printability, safety, environmental friendliness and excellent comprehensive performance.

Description

technical field [0001] The invention relates to the technical field of inks, in particular to a UV matte environment-friendly offset printing ink and a preparation method thereof. Background technique [0002] In daily life, people use a lot of printed products, such as lottery tickets, cigarette packs, various packaging boxes, etc., and also come into contact with newspapers, magazines, and books in large quantities. These products all have printing inks. UV offset printing ink is based on the action of ultraviolet radiation, relying on the free radicals or cations formed after the photoinitiator absorbs the radiation energy, triggering the polymerization, crosslinking and grafting reactions of monomers and oligomers to form a crosslinked three-dimensional network structure. Drying and curing of high molecular polymers. Most UV offset printing inks are composed of epoxy acrylic resins, polyester acrylic resins, acrylate monomers, photoinitiators, fillers, and organic pigme...
