Abstract

The invention discloses UV curing invisible fluorescent ink which is characterized by being prepared from the following raw materials by weight: 1 to 2 parts of ultraviolet fluorescence pigment, 10 to 15 parts of polyethylene glycol, 3 to 4 parts of urea, 1 to 2 parts of vinyl polysiloxane, 1 to 2 parts of polyoxyethylene stearic acid ether, 16 to 18 parts of tripropylene glycol diacrylate, 4 to 6 parts of zinc stearate, 20 to 24 parts of UV unsaturated polyester, 4 to 8 parts of a 184 photoinitiator, 1 to 2 parts of an antiager MB, 1 to 2 parts of tributyl tin trichloride, 5 to 7 parts of propenoic acid-4-hydroxybutyl ester, 12 to 14 parts of o-bromostyrene, 1 to 2 parts nonylphenol and 4 to 5 parts of an additve. The additive improves the toughness of the ink, enables the ink to be dispersed uniformly, and maintains the stability of the ink; the ink has multiple frequency converting anti-counterfeiting properties, the product can be dried instantaneously, and the ink has the characteristics of economy, energy conservation and environmental protection, and can be printed on absorptive printed materials or non-absorptive printed materials.

Description

technical field [0001] The invention relates to an ink and a preparation method thereof, in particular to a UV curing invisible fluorescent ink and a preparation method thereof. Background technique [0002] Invisible UV fluorescent ink: The materials used are invisible materials, and the printing process is simple. The ink prints invisible patterns or texts in the factory under ultraviolet light irradiation. Shows a clear and bright fluorescent pattern. colorful. The anti-counterfeiting detection is convenient, as long as there is an ultraviolet light source or a currency detector. Since the invisible fluorescent ink is invisible or colorless, it is invisible to the naked eye during printing, that is, there is no tracking mark recognized by any machine. Therefore, it is more difficult to overprint, but this kind of anti-counterfeiting concealment is better, and the anti-counterfeiting strength is stronger. Recently, most of the domestic pharmaceutical packaging uses thi...
