Embodiment 1

[0019] Mix 10 parts of C9 petroleum hydrocarbon resin, 0.1 part of polymerization inhibitor ST-1 and 15 parts of tripropylene glycol acrylate, and heat to 140°C to dissolve. Then add 15 parts of Cytec EB168 acrylic prepolymer, 0.2 parts of tert-butylcatechol, 4 parts of 4-phenylbenzophenone, 4 parts of 2-methyl-2-(4-morpholinyl)-1- [4-(methylthio)phenyl]-1-propanone, 10 parts of B-15:3 phthalocyanine blue, 2 parts of polymer dispersant BYK-163, stirred at 1000 rpm / min for 30 minutes. Pour the slurry into the bead ink machine, heat it to 60°C and grind it, grind it fully until the slurry fineness is less than 5 μm, add 20 parts of β-carboxyethyl acrylate, 20 parts of 1,6-hexanediol dipropylene Stir the ester evenly to get quick-drying environmental protection ink.

Embodiment 2

[0021] Mix 10 parts of C5 / C9 copolymer resin, 0.1 part of inhibitor ST-1 and 15 parts of tripropylene glycol acrylate, and heat to 140°C to dissolve. Then add 15 parts of Cytec EB168 acrylic prepolymer, 0.2 parts of tert-butylcatechol, 4 parts of 4-phenylbenzophenone, 4 parts of 2-methyl-2-(4-morpholinyl)-1- [4-(methylthio)phenyl]-1-propanone, 3 parts of B-15:3 phthalocyanine blue, 2 parts of polymer dispersant BYK-163, stirred at 1000rpm / min for 30 minutes. Pour the slurry into the bead ink machine, heat it to 60°C and grind it, grind it fully until the slurry fineness is less than 5 μm, add 23 parts of β-carboxyethyl acrylate, 24 parts of 1,6-hexanediol dipropylene Stir the ester evenly to get quick-drying environmental protection ink.

Embodiment 3

[0023] Mix 10 parts of C5 terpene-modified C5 resin, 0.1 part of polymerization inhibitor ST-1 and 15 parts of tripropylene glycol acrylate, and heat to 140°C to dissolve. Then add 15 parts of Cytec EB168 acrylic prepolymer, 0.2 parts of tert-butylcatechol, 4 parts of 4-phenylbenzophenone, 4 parts of 2-methyl-2-(4-morpholinyl)-1- [4-(methylthio)phenyl]-1-propanone, 6 parts of B-15:3 phthalocyanine blue, 2 parts of polymer dispersant BYK-163, stirred at 1000rpm / min for 30 minutes. Pour the slurry into the bead ink machine, heat it to 60°C and grind it, grind it fully until the slurry fineness is less than 5 μm, add 22 parts of β-carboxyethyl acrylate, 22 parts of 1,6-hexanediol dipropylene Stir the ester evenly to get quick-drying environmental protection ink.

Abstract

The invention discloses a quick-drying environmental-protection ink preparation method, wherein the ink comprises, by weight, 10-30 parts of a hydrocarbon resin, 10-30 parts of an acrylic acid prepolymer, 0.1-1 part of a polymerization inhibitor, 5-12 parts of a photoinitiator, 5-10 parts of a pigment, 1-5 parts of a dispersant, and 20-50 parts of an acrylic monomer. According to the present invention, the ink is suitable for flexographic printing machines, and is instantaneously dried by an ultraviolet lamp so as to greatly improve the working efficiency; the ink can resist strong acid etching after being dried, wherein the concentration of the etching acid can be freely increased, the temperature of the etching liquid can be increased, and the etching time can be increased so as to meetthe processing requirements of various RFID tags; the ink is easily subjected to alkali washing after being dried and etched, and the deinking can be achieved within 5-20 s with a 3% NaOH solution; and with the quick-drying environmental-protection ink, the clean circuit surface with no ink residue can be effectively achieved so as to ensure the quality of the final product.

Description

technical field [0001] The invention relates to an ultraviolet light curing ink composition and method, and a gravure printing method, mainly a preparation method of a quick-drying environmental protection ink. Background technique [0002] RFID is a non-contact automatic identification technology. It automatically identifies the target object and obtains relevant data through radio frequency signals. The identification work does not require manual intervention and can work in various harsh environments. RFID technology can identify high-speed moving objects and can identify multiple tags at the same time. [0003] At present, RFID inks include ordinary gravure inks and UV screen inks. Ordinary gravure printing ink has good leveling performance, straight vertical and horizontal lines after printing, no jaggedness, fast printing speed, good acid resistance, no dew point after etching, easy to wash with alkali; but gravure printing ink contains a lot of solvents, It belongs ...
