AI Technical Summary

Problems solved by technology

The gloss of UV ink fountain varnish can be very high, but it is generally a little yellowish, which will affect the color of printed matter, especially when varnishing some spot colors.
[0005] At present, the printing of cigarette labels and cigarette packs in the market requires high gloss, but also has good color and luster, and there should be no color deviation, especially yellowish phenomenon.

Embodiment 1

[0023] In this example, the ultraviolet curable resin is a mixed resin composed of modified epoxy acrylic resin, thermoplastic acrylic resin and multifunctional polyurethane acrylate, and the reactive diluent is acryloyl morpholine (ACMO) and trimethylolpropane triacrylic acid. ester (TMPTA), the photoinitiator is 2-phenylbenzyl-2-dimethylamine-1-(4-morpholinebenzylphenyl) butanone (JRCure 369) and 2,4-diethylthioxanthene Two kinds of ketone (JRCure DETX) are mixed, Wet 500 is selected as the wetting agent, polyether modified polydimethylsiloxane (BYK306) is selected as the leveling agent, and p-hydroxyanisole is selected as the polymerization inhibitor.

[0024] 1. Mix 25 parts of trimethylolpropane triacrylate (TMPTA) and 10 parts of acryloyl morpholine (ACMO) and stir well.

[0025] 2. Add 7 parts by weight of thermoplastic acrylic resin, 10 parts by weight of modified epoxy acrylic resin and 10 parts by weight of tetrafunctional aliphatic urethane acrylate; add 3 parts by ...

Embodiment 2

[0028] In this example, the ultraviolet curable resin is a mixed resin composed of modified epoxy acrylic resin, thermoplastic acrylic resin and multifunctional polyurethane acrylate, and the reactive diluent is acryloyl morpholine (ACMO) and trimethylolpropane triacrylic acid. ester (TMPTA), the photoinitiator is 2-phenylbenzyl-2-dimethylamine-1-(4-morpholinebenzylphenyl) butanone (JRCure 369) and 2,4,6-trimethylbenzene Ethyl formyl phosphonate (JRCure TPO-L) is mixed with Wet 500, BYK306 and p-hydroxyanisole as additives.

[0029] 1. Mix 27 parts of trimethylolpropane triacrylate (TMPTA) and 15 parts of acryloyl morpholine (ACMO) and stir well.

[0030] 2. Add 11 parts by weight of thermoplastic acrylic resin, 15 parts by weight of modified epoxy acrylic resin and 14 parts by weight of a mixed resin composed of four-functional aliphatic urethane acrylate, and then add 4 parts by weight of photoinitiator JRCure 369 and 4 The photoinitiator JRCure TPO-L of parts by weight and...

Embodiment 3

[0033] 1. Mix 30 parts of trimethylolpropane triacrylate (TMPTA) and 20 parts of acryloyl morpholine (ACMO) and stir well.

[0034] 2. Add 15 parts by weight of thermoplastic acrylic resin, 20 parts by weight of modified epoxy acrylic resin and 17 parts by weight of tetrafunctional aliphatic urethane acrylate; then add 3 parts by weight of photoinitiator JRCure 369, 3 The photoinitiator JRCure DETX in parts by weight, the photoinitiator JRCure TPO-L in 4 parts by weight and the photosensitizer in 10 parts by weight were stirred evenly and fully dissolved.

[0035] 3. Finally, add 2.1 parts by weight of additives (1 part of Wet 500, 1 part of BYK306, 0.1 part of p-hydroxyanisole), stir evenly and filter, and use a Tu 4# cup to test the viscosity of the product in 18-22 seconds to be qualified Finished UV ink fountain varnish.

Abstract

The invention relates to a UV (ultraviolet) duct gloss oil and a preparation method of the UV duct gloss oil. The UV duct gloss oil is prepared by raw materials consisting of ultraviolet cured resin, an active diluting agent, a photo-initiator, and and the like; weight proportion of each component is as follows: 27-52 parts of ultraviolet cured resin, 35-50 parts of active diluting agent, 5-10 parts of photo-initiator, 8-10 parts of photo sensitive sensitizer, and 1.05-2.1 parts of assistant. After using the UV duct gloss oil prepared according to the proportion of the invention for cigarette-brand printing, the cigarette-brand is bright and beautiful in color, strong in transparence, high in wearing resistant degree, and better in the entire printing effect.

Description

technical field [0001] The invention relates to a water-based ink fountain varnish for offset printing, in particular to a UV ink fountain varnish and a preparation method thereof. Background technique [0002] In offset printing, the main function of coating and glazing is to protect the printed matter, and it can also make the product obtain different printing effects, increase the aesthetic feeling, and thus increase the value of the printed matter. In addition, it can also meet the needs of post-processing. There are basically three methods of coating and varnishing: separate glazing machine, printing machine on-line glazing equipment and printing machine ink fountain unit glazing. Using ink fountain varnish is like using printing ink. Use an ink shovel to scoop the varnish into the ink fountain. After turning the varnish evenly on the ink roller, the varnish can be applied. The varnish is carried to the printing plate by the ink roller, then transferred from the print...
