Embodiment 1

[0024] Embodiment 1 Preparation of UV gravure printing RFID dark blue ink

[0025] 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 1000rpm / min for 30 minutes. Pour the slurry into the bead ink machine, heat it to 60°C and grind it, and grind it fully until the slurry fineness is less than 5 μm, then add 20 parts of β-carboxyethyl acrylate and 20 parts of 1,6-hexanediol dipropylene Stir the ester evenly to get UV gravure RFID blue ink.

Embodiment 2

[0026] Example 2 Preparation of UV gravure RFID light blue ink

[0027] Mix 10 parts of C5 / C9 copolymer 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, 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, and grind it fully until the slurry fineness is less than 5 μm, then add 23 parts of β-carboxyethyl acrylate and 24 parts of 1,6-hexanediol dipropylene Stir the ester evenly to get UV gravure RFID blue ink.

Embodiment 3

[0028] Embodiment 3 Preparation of UV gravure printing RFID blue ink

[0029] 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, and grind it fully until the slurry fineness is less than 5 μm, then add 22 parts of β-carboxyethyl acrylate and 22 parts of 1,6-hexanediol dipropylene Stir the ester evenly to get UV gravure RFID blue ink.

Abstract

The invention discloses UV gravure RFID printing ink and a preparation method thereof; the UV gravure RFID printing ink comprises, by weight:10-30 parts of petroleum resin, 10-30 parts of acrylic acid prepolymer, 0.1-1 part of a polymerization inhibitor, 5-12 parts of a photoinitiator, 5-10 parts of pigment, 1-5 parts of a dispersant, and 20-50 parts of acrylic acid monomers. The UV gravure RFID printing ink of the invention has the following beneficial effects: the printing ink is suitable for gravure press and flexo-graphic machines, is instantly dried by an ultraviolet lamp, which greatly increases the working efficiency. After dried, the printing ink can resist strong acid etching; the concentration of the etching acid can be adjusted at will; the etching solution temperature can be increased; the etching time can be increased; and thus processing of various RFID labels can be met. After drying and etching, the printing ink is easy to be washed by alkalis, and a 3% NaOH solution can remove the ink within 5-20 seconds. The line surface is effectively maintained to be clean and free of printing ink residues, and thus the final product quality is ensured.

Description

technical field [0001] The invention relates to an ultraviolet light curing ink composition and method, and a gravure printing method, mainly a UV gravure RFID ink and a preparation method thereof. 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 to dangerous ...
