Abstract

The invention relates to UV (Ultraviolet light) snowflake printing ink. The UV snowflake printing ink is prepared from the following components in parts by weight: 43-55 parts of an active monomer, 12-25 parts of polyurethane acrylate, 8-20 parts of polyketone resin, 3-9 parts of a photoinitiator and appropriate amount of an additive; the active monomer is selected from one or more of bifunctionalgroup acrylic ester and trifunctional group acrylic ester. Under illumination of UV, the photoinitiator is dissociated into free radicals to promote the crosslinked polymerization of the active monomer, the polyurethane acrylate and the polyketone resin, and special texture is generated; through regulating and controlling the component content of a dipropylene glycol diacrylate monomer, the polyurethane acrylate, the polyketone resin, the photoinitiator and the additive, the drying time of the UV snowflake printing ink is shortened to be within 2 s; the drying speed can keep up with the speedof online gravure; the UV snowflake printing ink is applicable to rotary gravure online printing; the printing speed can reach 10,000 pieces / hour or above; the printing efficiency of the snowflake printing ink is greatly improved; the printing cost is lowered.

Description

technical field [0001] The invention relates to the technical field of printing materials and technology, in particular to UV snowflake ink. Background technique [0002] UV (ultraviolet light) curing gravure snowflake printing is a special process for surface treatment of printed matter, which can produce transparent three-dimensional patterns on the color printing pattern of printed matter, making the printed pattern present a novel and high-end effect. UV curing snowflake ink first prints the ink on the pattern surface of the printed matter through the printing machine, and then detonates and solidifies to present a crystal clear texture texture like winter snowflakes. It is a special craft ink of fission and crystallization. [0003] The current UV snowflake ink is mainly suitable for screen printing and sheet-fed gravure printing, and the printing production efficiency per unit time is obviously low. Contents of the invention [0004] Based on this, the present inven...
