Abstract

The invention relates to a UV (ultraviolet) paper varnish and a preparation method thereof. The UV paper varnish comprises the following components in percentage by weight: 20-50% of acrylic resin, 50-80% of diluent monomers, 5-10% of activated amine, 3-9% of a light initiator and 0.1-1% of a flatting agent, wherein the acrylic resin is selected from epoxy acrylate, urethane acrylate or polyester acrylate; the activated amine is selected from methyldiethanolamine; the light initiator is selected from one of diphenyl ketone and 2-hydroxy-2-methyl-1-phenyl-1-acetone or 1-hydroxy-cyclohexyl phenyl ketone and used through compounding, and the mass ratio of the diphenyl ketone to another light initiator is (1-5):1; and the flatting agent is selected from BYK301 produced by Germany BYK. The UV paper varnish disclosed by the invention has the advantages of simple production process, good wear resistance, low volatile matter content, energy conservation, environmental protection, and stable product quality.

Description

technical field [0001] The invention relates to a UV paper varnish and a preparation method thereof, which is used for glazing various paper packages such as cigarette labels, wine labels, books and magazines, and belongs to the technical field of chemical industry. Background technique [0002] The so-called printing glazing is to print the varnish once or twice with a solid printing plate or a graphic printing plate on the surface of the replica that has completed the graphic printing, so that the surface of the printed matter can obtain a bright VU film. Printing glazing can enhance the light fastness of the ink, increase the heat resistance and moisture resistance of the ink layer, and play the role of protecting imprinted beautification products instead of lamination. [0003] UV varnish is a method of curing glazing paint by UV (abbreviation for Ultra Viole, ie ultraviolet light) irradiation. With the characteristics of fast curing and low temperature curing of coatin...
