Abstract
The invention discloses LED-UV curing offset ink which comprises a nano rare earth material capable of changing the ultraviolet light absorbing peak value of UV curing ink. The LED-UV curing offset ink has the advantages that through addition of the nano rare earth material, the ultraviolet light absorbing peak value of the UV curing ink is changed, and the LED-UV single-wave band absorption value of the UV curing ink is larger, so that the energy of an LED-UV lamp can be utilized better, the ink curing effect can be improved, and the LED-UV curing offset ink can be cured sufficiently when the irradiation light brightness value of the low-energy LED-UV lamp reaches 15 mJ/cm<2>.
Description
Technical field
The present invention relates to a kind of ink, be specifically related to a kind of by nano rare earth change LED-UV absorption of inks crest, and then promote the flexographic ink of ink solidification.
Background technology
At present; ultraviolet cured offset printing ink generally adopts UV high voltage mercury lamp to be cured; have that energy consumption is high, thermal value is large, work-ing life is short, be unfavorable for the defects such as environment protection; and common UV flexographic ink dry difficulty under LED-UV light source, so need one newly developed can under LED-UV light source quick-drying flexographic ink.LED-UV flexographic ink in the market mainly improves radiation curing resin functionality to realize by adjustment light trigger collocation increase photoinitiator levels on Conventional UV light-curable ink base material, the ink researched and developed by this method proposes high requirement to LED-UV lamp energy, the power of LED-UV lamp is needed to be the bigger the better, be limited to the development of LED-UV lamp technology, LED-UV ink industry promoted slower.
Summary of the invention
For overcoming above-mentioned technological deficiency, the invention discloses a kind of by Nano Rare-earth Materials change LED-UV absorption of inks crest, and then promoting the flexographic ink of ink solidification.
Technical scheme of the present invention is as follows: a kind of LED-UV cured offset printing ink, and containing Nano Rare-earth Materials, described Nano Rare-earth Materials can change the outer curing inks of purple light to ultraviolet absorption peak value.

Described Nano Rare-earth Materials weight content is 0.5%-2%, add the Nano Rare-earth Materials within the scope of this, make ink larger to the single wave band absorption value of LED-UV, thus improve the utilization ratio to LED-UV lamp energy, improve ink solidification effect, make low-yield LED-UV light irradiation 15mJ/cm
2can solidify fully.
LED-UV cured offset printing ink of the present invention containing, for example each component of lower weight content,
Described radiation curing resin is one or both mixtures of epoxy acrylate, polyester acrylate, polyether acrylate, urethane acrylate.
Described light trigger is 2-dimethylamino-2-benzyl-1-[4-(4-morpholinyl) phenyl]-1-butanone, 1-hydroxy-cyclohexyl-phenyl ketone, alpha-alcohol ketone, 2, 4, 6-trimethylbenzoy-dipheny phosphine oxide, ethyl (2, 4, 6-trimethylbenzoyl)-Phenylphosphine formic acid, 4-(dimethylamino)-phenylformic acid-(2-ethyl) own ester, 2, 4-diethyl thioxanthone, o-benzoyl yl benzoic acid methyl esters, EDMAB, 2-methyl-2-(4-morpholinyl)-1-[4-(methylthio group) phenyl]-1-acetone, methyl benzoylformate, 4, 4 '-two (diethylin) benzophenone, two kinds or two or more mixtures of two aroyl phosphoric-oxygenic compound.
Described auxiliary agent is one or both mixtures in three (N-nitroso-group-N-Phenylhydroxylamine) aluminium salt, tertiary butyl benzoquinones, the 6-tertiary butyl-2,4-xylenol, MEHQ, N-nitroso-N-phenylhydroxylamine ammonium salt.
Beneficial effect of the present invention is:
(1) the present invention is by adding Nano Rare-earth Materials in uv curing ink, and then change the absorption crest of UV curable ink, coordinate light trigger and resin adjustment, develop a kind of low-yield LED-UV cured offset printing ink, being applied to and producing single ultraviolet wavelength is one or more LED-UV cure systems combined such as 365nm, 360nm, 375nm, 385nm, 390nm, 395nm.
(2) the present invention changes ink to the absorption crest of UV-light by adding Nano Rare-earth Materials, make it larger to LED-UV single wave band absorption value, thus the utilization ratio improved LED-UV lamp energy, improve ink solidification effect, reach low-yield LED-UV light irradiation 15mJ/cm2 and solidify sufficient object.
