Description
Technical field:
The present invention relates to technical field of ink, relate in particular to a kind of flexible ultraviolet light curing offset printing ink.
Background technology:
Ultraviolet cured offset printing ink is owing to have characteristics such as do not contain VOC, non-stimulated, water-fast anti-solvent, surface luster is good, curing speed is fast, in printing industry by more and more widely application.Because the ultraviolet cured offset printing ink of fatty acid modified polyester acrylic just was widely used since the seventies.
In order to improve the performance of printing ink all respects, people have done a large amount of research, as: Chinese patent CN200710072807 discloses bright printing ink of a kind of ultraviolet cured adhesive printthrough and preparation method thereof, by fine ground pigment of elder generation and dyestuff, again the pigment after fine ground, dyestuff and part polyester acrylic ester oligomer and reactive thinner are mixed pre-slurry and fine ground, add remaining polyester acrylic ester oligomer and reactive thinner, light trigger, dispersion agent then, operations such as high-speed stirring make; This product has overcome that existing ultraviolet curing transparent ink setting speed is low, the easy gel of product, viscosity are difficult to defectives such as control.Chinese patent CN200580019222 relates to the radiation curable ink of lithography purposes, because polyfunctional acrylic ester resin, it is by (for example making acrylate monomer and oligopolymer and β-keto ester, acetylacetic ester), β-diketone (for example, 2,4-diacetylmethane), β-keto-amide (for example, Acetanilide, aceto-acetamide) and/or other β-dicarbonyl compound that can participate in Michael reaction react and form.Japanese Patent JP49-94788 discloses the synthetic method of styrene allyl alcohol acrylate, and it is diluted in, and the ultraviolet light polymerization as printing-ink connects material in the trimethylolpropane trimethacrylate.European patent EP 03019345.2 relates to a kind of uV curable composition of ultraviolet light polymerization planography printing ink, comprise one or more (methyl) alkyl acrylates to styrene allyl alcohol (SAA) multipolymer and at least a alkoxylate (methyl) acroleic acid esterification monomer, it obtains bigger improvement on curing speed.
From above-mentioned disclosed technology, along with development of science and technology, the various aspects of performance of printing ink has had very big improvement; But still exist its ink-water balance, pigment wetting, viscosity, snappiness etc. can not satisfy the defective of high speed printing, especially at extra package industries such as tobacco bale, plastics films, can not satisfy the also very fast requirement of curing speed when having very high-flexibility.
Summary of the invention:
The objective of the invention is at the deficiencies in the prior art, and disclose a kind of fabulous flexible ultraviolet cured offset printing ink that has.
The objective of the invention is to be achieved by the following method:
A kind of flexible ultraviolet light curing offset printing ink; The raw material that comprises following mass percent:
Modified acroleic acid ester oligomer 40 ℅～80 ℅
Acrylic ester monomer 5 ℅～20 ℅
Light trigger 5 ℅～15 ℅
Pigment 10 ℅～25 ℅
Filler/auxiliary agent 1 ℅～8 ℅
The modified acroleic acid ester oligomer is synthetic by the acrylate component of SAA resin, diprotic acid, hydroxyl.
Wherein, described modified acroleic acid ester oligomer is synthesized into by the raw material of following mass parts:
400 parts～700 parts of SAA resins
5 parts～12 parts of diprotic acid
200 parts～400 parts of the acrylate of hydroxyl
10 parts～20 parts of divinyl
500 parts～1500 parts of toluene
20 parts～60 parts of MEHQ
0.1 part～1 part in Red copper oxide.
The building-up process of described modified acroleic acid ester oligomer is: the raw material of above-mentioned amount is added in the reactor, under the state of stirring temperature in the reactor is slowly risen to 110 ℃, 110 ℃ of reactions 8～12 hours down, slow down to speed of response; Reactor continues insulation and continues to stir, detected the acid number of above-mentioned reaction mass every 5～25 minutes, when acid number≤5mgKOH/g, reactor is cooled to 90 ℃, be decompressed to 100mmHg, toluene distillation is not after having the toluene outflow, continue to reduce temperature, viscosity is 1000～1500paS/30 ℃ modified poly ester acrylic ester oligomer.
Described SAA resin is allyl group, cinnamic multipolymer.
Described diprotic acid is a kind of or mixing in dilute sulphuric acid, the Hypophosporous Acid, 50.
The acrylate of described hydroxyl is one or more in pentaerythritol triacrylate, hydroxyethyl methylacrylate, the poly-hexadiene mono acrylic ester.
Wherein, the above acrylic ester monomer of the preferred trifunctional of described acrylic ester monomer one or more.
Wherein, described light trigger is one or more in benzil and derivative thereof, dialkoxy methyl phenyl ketone class, α～hydroxyalkyl benzophenone class, the α～amine alkylaryl ketone.
Wherein, described pigment is selected from one or more in permanent bordeaux, permanent yellow, phthalein mountain valley with clumps of trees and bamboo orchid, titanium white, the carbon black.
Wherein, described filler/auxiliary agent is one or more in lime carbonate, magnesiumcarbonate, talcum powder, organobentonite, polyethylene wax, Poly Propylene Wax, tetrafluoroethylene wax, Fischer-Tropsch wax, dispersion agent, the optical brightener.
Certainly, also can add other components in the printing ink, as stablizer, wetting agent, defoamer, adhesion promoter, dispersion agent etc.
The modified acroleic acid ester oligomer of said ratio, acrylic ester monomer, light trigger, pigment, filler/auxiliary agent etc. are dropped in the container, disperse under the rotating speed of 1500r/min with dispersion machine, after being uniformly dispersed, go to three-roller and grind, be ground to fineness＜7.5 μ m and be prepared into flexible ultraviolet light curing offset printing ink.
The invention has the beneficial effects as follows, the present invention includes modified acroleic acid ester oligomer, acrylic ester monomer, light trigger, pigment, filler/auxiliary agent; Wherein, because the modified acroleic acid ester oligomer is synthetic by the acrylate component of SAA resin, diprotic acid, hydroxyl; Hydroxy radical content in the SAA resin is many, this causes synthetic back UV-cured resin functionality very big, though curing speed is very fast, but also lost its snappiness simultaneously, adopt the acrylate and the SAA resin of diprotic acid and hydroxyl synthetic, can increase the snappiness of UV-cured resin, make it have fabulous snappiness, do not lose simultaneously its curing speed again, acrylic ester monomer corrodes less to rubber roll; So the present invention not only has very high-flexibility, curing speed is also very fast simultaneously, especially is used in extra package industries such as tobacco bale, plastics film.
