But it is following not enough to adopt the ink of UV cure lamp to exist at present: the time of drying of ink is longer; Have ozone generation, the generation of ozone to human respiratory also at certain damaging effect; Energy consumption is large, approximately needs 10 kilowatts ~ 30 kilowatts, temperatures as high 200 DEG C; Filtering membrane for isolating UV light is inflammable; Fluorescent tube is short for work-ing life, and printing cost is strengthened; UV light has radiation effect to people, easily causes the untoward reactions such as skin dermatitis.The present invention adopts and improves LED-UV light source curable is environmental protection mode, does not produce ozone and other obnoxious flavoures, makes it be applicable to the packaging of food product pack and other decorations, simultaneously can be energy-conservation, be equivalent to 20 ~ 30% of common UV energy consumption, it also avoid inflammable problem, improve security.
Summary of the invention
The present invention proposes a kind of LED-UV flexographic ink and its production and use, solves the problem of curing inks in prior art time of drying is long, energy consumption is large, cost is high and bring potential safety hazard and environmental pollution.
Technical scheme of the present invention is achieved in that a kind of LED-UV flexographic ink, comprise binder, reaction monomers, photosensitizers, stopper, tinting material and thinner, reaction monomers comprises medium viscosity reaction monomers and low viscosity reaction monomers, its consisting of by weight percentage: binder accounts for 45 ~ 60% of total amount, medium viscosity reaction monomers accounts for 9 ~ 19% of total amount, low viscosity reaction monomers accounts for 1 ~ 10% of total amount, photosensitizers accounts for 1 ~ 12% of total amount, stopper accounts for 0.01% of total amount, tinting material accounts for 10 ~ 15% of total amount, thinner accounts for 1 ~ 15% of total amount, the weight percent sum of all components is 100%.
Preferably, binder is origoester acrylate specifically, origoester acrylate be specially in the oligopolymer of the oligopolymer of modified epoxy acrylic ester, the oligopolymer of modified polyester acrylate ester, the oligopolymer of polyurethane-modified polyacrylate and 1,6-hexylene glycol acrylate one or more.
Preferably, medium viscosity reaction monomers is specially Viscoat 295 or pentaerythritol triacrylate; Low viscosity reaction monomers is specially the one in tripropylene glycol diacrylate, two contracting propylene glycol double methacrylates or 1,6 hexanediol diacrylate.
Preferably, photosensitizers is specially free radical I type photosensitizers, free radical II type photosensitizers or heavy duty detergent photosensitizers; Free radical I type photosensitizers is specially the one in dimethylaminobenzyl morpholino phenyl butanone, dimethylaminomorpholine base phenyl butanone or hydroxyl dimethyl benzene benzylacetone; free radical II type photosensitizers is specially benzoylphosphine oxide or hydroxycyclohexyl phenyl ketone, and heavy duty detergent photosensitizers is specially formylphosphonic acid ethyl ester or Three methyl Benzene acylphosphine oxide.
Preferably, stopper is specially one or both in para benzoquinone, Resorcinol and p-ten.-butylcatechol.
Preferably, tinting material is specially the one in colour carbon black series, phthalocyanine blue series, azo series or color lake series; Thinner is specially one in aerosil, ultrafine calcium, aluminium hydroxide and wax powder or two kinds.
Preferably, also comprise dispersion agent, dispersion agent accounts for 1 ~ 2% of total amount by weight percentage, and dispersion agent is specially powdered dispersing agents, colloidal dispersion agent or liquid dispersant.
A preparation method for LED-UV flexographic ink, comprises the steps:
1) weigh binder, reaction monomers and photosensitizers according to selected weight percent, adopt high dispersive machine to be mixed fully, obtain mixture A;
2) weighing tinting material, stopper and thinner according to selected weight percent adds in mixture A, and adopt homogenizer to be mixed, fully disperse, and be heated to 60 ~ 80 DEG C, insulation, until all dissolve, obtains mixture B;
3) mixture B is fully ground by three-roll grinder, form slurry lotion;
4) detect and adjust the slurry rheological of lotion and photosensitivity, within the scope of the print speed enabling slurry lotion realize 70 ~ 80m/min, realizing the solidification of LED cold light source.
Preferably, step 2) in also add dispersion agent; Step 3) in after grinding steps the granularity of flexographic ink be 2 ~ 15 μm.
A purposes for LED-UV flexographic ink, flexographic ink is used for the sheet-fed printing of metal foil paper, compound gold and silver paperboard, composite laser paper, synthetic paper, transfer paper, polychlorovinyl sheet material, polyester sheet, crystalline p p sheet and polyethylene sheets; Flexographic ink is applicable to offset press, and offset press specifically comprises single-colour offset press, two color offset press and four-color machine offset press.
Wherein, binder is main body filmogen; Reaction monomers is auxiliary film forming material, is also thinner simultaneously.Binder is in ink, the material mixing such as the pigment of powdery can link up by it, make it after grinding distribution, form the adherent with certain degree of mobilization and viscosity, thus play link effect, determine the degree of mobilization of ink, viscosity, dryness and printability etc.Reaction monomers is the polyfunctional group reaction monomers at least in reactive group carbonyl, carboxyl and hydroxyl with one or more.
The present invention suitably selects thinner, mainly plays filling effect, can reduce colorant concentrations in addition and reduce costs, can also regulate the character of ink, as rare denseness and rheological etc.Photosensitizers is for providing photoabsorption, causing the function of crosslinking reaction.Utilize binder, reaction monomers (polyfunctional group reaction monomers, if reactive group is carbonyl, carboxyl and hydroxyl etc.), stopper and photosensitizers, tinting material and thinner, slurry lotion is formed by mixing, dispersion and grinding, reach certain tinting strength, concentration, viscosity, thixotropy and plasticity, meet the principle of ink-water balance, obtain LED-UV flexographic ink of the present invention.
