UV rubber blanket and preparation method thereof

Abstract

The invention provides a UV rubber blanket and a preparation method thereof. The UV rubber blanket at least comprises a first base material layer and a second base material layer, the bonding layer is located on the first base material layer; the second base material layer is positioned on the bonding layer; the foaming layer is positioned on the second base material layer; the third base material layer is positioned on the foaming layer; the surface adhesive layer is positioned on the third base material layer; wherein the surface adhesive layer and the foaming layer comprise ethylene propylene diene monomer. According to the prepared UV rubber blanket, the surface rubber layer directly making contact with printing ink contains ethylene propylene diene monomer, and the UV rubber blanket has excellent chemical corrosion resistance and water resistance and can resist corrosion of UV printing ink and a UV printing ink cleaning agent; the foaming layer comprises the ethylene propylene diene monomer, has the compressibility of 0.16-0.22 mm under the pressure intensity of 10 kg / cm < 2 >, and is excellent in compression performance.

Description

technical field [0001] The invention belongs to the technical field of lithographic printing, and in particular relates to a UV blanket and a preparation method thereof. Background technique [0002] The UV blanket used in offset printing (lithographic printing) is made of multi-layer base fabric layer and synthetic rubber calendered laminated blanket, which is wrapped on the transfer cylinder for transferring ink to the substrate (such as paper) s surface. [0003] UV ink (ultraviolet curable ink) refers to an ink that undergoes an instantaneous photochemical reaction under the irradiation of ultraviolet light of a certain wavelength to polymerize the monomers in the ink binder into polymers, and make the ink film-forming and drying. Due to its fast drying speed, good gloss, bright colors, water resistance, solvent resistance, wear resistance and other characteristics, the proportion of UV ink in the printing industry has continued to increase in recent years.

Problems solved by technology

[0005] However, the existing blankets for UV printing are mostly monopolized by countries such as Europe, the United States, and Japan, and the domestically produced blankets for UV printing still cannot meet the requirements for use.
