Description
Technical field
The present invention relates to printing process, and in particular to a kind of silk-screen printing technique.
Background technology
UV silk-screen wrinkle techniques are a kind of typography generally used in current printing industry, the dicoration of the technique
By force, it can make printed matter that there is good metal sense, visual impact is strong, can attract consumer's eyeball, can improve the attached of printed matter
It is value added.
However, the obvious defect of existing UV silk-screens wrinkle technique generally existing one, that is, apply in background color than shallower card
UV curable ink (UV ink) and formed when on paper or art post paperboard, in printing after ink printed layer, if printed matter is placed on
Shone under available light, (such as 1 hour) will yellowing, anti-yellowing property pole completely within a very short time for its ink printed layer
Difference.Although and some UV silk-screen wrinkle techniques preferably overcome the problem of ink printed layer anti-yellowing property is poor, ink print
Brush layer is more crisp, is easily burst during bending, folding resistance is poor, and there are the problem of machine volatile matter is exceeded toward contact.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of silk-screen printing technique, and this silk-screen printing technique utilizes purple
Outer light-curable ink can form the ink printed layer with wrinkle effect, the ink printed layer has good after printing, solidification
Good anti-yellowing property and folding resistance.The technical scheme of use is as follows：
A kind of silk-screen printing technique, it is characterised in that comprise the steps successively：
(1) screen printing forme is made；
(2) screen printing forme made is installed on silk-screen printing device, and adds UV curable ink and printed
Brush, forms ink for screen printing layer on the substrate；
The component that UV curable ink used is matched by following weight is constituted：Urethane acrylate 24-35%,
Epoxy acrylate 14-25%, tri (propylene glycol) diacrylate 15-25%, three acrylic acid propane front three alcohol ester 15-
25%, double [2- hydroxy-2-methyl -1- acetone] 0.5-2.5% of 1,1'- (methylene two -4,1- phenylenes), polymerize [2- hydroxyls
Base -2- methyl isophthalic acids-[4- (1- methyl ethylenes) phenyl] acetone] 0.5-1.5%, dimethyl silicone polymer 0.1-1%, polyethers
Modified polyorganosiloxane 0.1-1%, Tissuemat E 1-5%；
(3) it is 200-300 nanometers of ultraviolet light ink for screen printing layer using wavelength, makes the ink for screen printing on stock
The top layer solidification of layer；
(4) it is 360-400 nanometers of ultraviolet light ink for screen printing layer using wavelength, makes the ink for screen printing on stock
Layer solidification, forms ink printed layer.
In above-mentioned steps (1), screen printing forme can be made using conventional method.In preferred steps (1), using 200-400 mesh
Silk screen make screen printing forme；Screen printing forme is more preferably made using the silk screen of 350 mesh.
In above-mentioned steps (2), silk-screen printing device, printing process can use conventional screen printing equipment and method.
In above-mentioned steps (3), the ultraviolet light that wavelength is 200-300 nanometers is launched using low pressure mercury lamp.
It is preferred that in above-mentioned steps (3), utilizing time of the wavelength for 200-300 nanometers of ultraviolet light ink for screen printing layer
For 0.5-1 seconds.
In above-mentioned steps (4), the ultraviolet light that wavelength is 360-400 nanometers is launched using conventional UV lamp.
It is preferred that in above-mentioned steps (4), utilizing time of the wavelength for 360-400 nanometers of ultraviolet light ink for screen printing layer
For 0.05-0.1 seconds.
After above-mentioned steps (3) and the solidification of step (4) ultraviolet light, the ink printed layer of formation has wrinkle effect, and it rises
Wrinkle principle be：UV curable ink, which is printed onto on stock, to be formed after ink layer ink for screen printing layer, is 200- first with wavelength
300 nanometers of ultraviolet light ink for screen printing layer, is inhaled completely because the ultraviolet light of the wave band is basic on ink for screen printing layer top layer
Receive, it is impossible to be penetrated into ink for screen printing layer bottom, therefore produce cure shrinkage on ink for screen printing layer top layer and form wrinkle, but silk-screen
Ink layer bottom does not react now；Followed by wavelength silk-screen oil is further irradiated for 360-400 nanometers of ultraviolet light
Layer of ink, by the thoroughly solidification of ink for screen printing layer, forms the ink printed layer with wrinkle effect.
In preferred scheme, above-mentioned silk-screen printing technique also includes step (5), using infrared drying equipment to being formed with oil
The stock for inking brush layer carries out drying and processing, and takes the gas being evaporated away using extractor fan.More preferably step (5)
In, drying temperature is 100-140 DEG C.The acetone evaporated in ink printed layer is come out by drying, and will by extractor fan
It is taken away, substantially reduces the content of acetone of printed matter, and the problem of printed matter acetone is exceeded can be solved well.
Above-mentioned urethane acrylate and epoxy acrylate are all the low-molecular-weight resins containing " C=C " unsaturated double-bond,
Be ink is dried on stock surface, set and film forming, both groups
Closing makes the ink printed layer (being commonly called as ink film) formed after solidification have splendid rub resistance, tack, light resistance, resistance toization
Learn moral character, and higher hardness.
Above-mentioned tri (propylene glycol) diacrylate and three acrylic acid propane front three alcohol esters are used as UV curable ink
Reaction diluent, can reduce ink viscosity, play peptizaiton, and participate in the curing reaction of UV ink, can improve UV ink
Curing rate, strengthens the adhesive force of ink printed layer.
The structural formula of above-mentioned the 1,1'- (- 4,1- phenylenes of methylene two) double [2- hydroxy-2-methyl -1- acetone] is：
In above-mentioned UV curable ink, 1,1'- (methylene two -4,1- phenylenes) double [2- hydroxy-2-methyls -1- third
Ketone], polymerization [2- hydroxy-2-methyls -1- [4- (1- methyl ethylenes) phenyl] acetone] collectively as light trigger, wherein, gather
[2- hydroxy-2-methyls -1- [4- (1- methyl ethylenes) phenyl] acetone] is ultra etiolation-resistance light trigger, has ink printed layer
There is preferably anti-yellowing property, 1,1'- (methylene two -4,1- phenylenes) double [2- hydroxy-2-methyl -1- acetone] then reacts work
Property is relatively low, can improve the folding resistance of kind ink printed layer.Under the irradiation of ultraviolet light, light trigger (1,1'- (methylene two -4,
1- phenylenes) double [2- hydroxy-2-methyl -1- acetone] and polymerization [2- hydroxy-2-methyls -1- [4- (1- methyl ethylenes) benzene
Base] acetone]) absorb energy production free radical, free radical under high speed activities, with urethane acrylate, epoxy acrylate,
Tri (propylene glycol) diacrylate, three acrylic acid propane front three alcohol esters produce collision, transfer energy to polyurethane acroleic acid
Ester, epoxy acrylate, tri (propylene glycol) diacrylate, three acrylic acid propane front three alcohol esters, make it open double bond, carry out
Cross linking reaction and solidification.By the 1,1'- (- 4,1- phenylenes of methylene two) double [2- hydroxy-2-methyl -1- acetone] and it is poly- [2- hydroxyls -
2- methyl isophthalic acids-[4- (1- methyl ethylenes) phenyl] acetone] it is jointly added in ink, can print the UV curable ink
The ink printed layer that is formed after brush is while have good anti-yellowing property and folding resistance.
It is preferred that the molecular formula of above-mentioned dimethyl silicone polymer (i.e. dimethicone) is (CH3)3SiO[(CH3)2SiO]nSi
(CH3)3, wherein n is 5-100 natural number.Above-mentioned dimethyl silicone polymer can prevent ink layer from phenomenon of growing dim occur.
The main function of above-mentioned Siloxane-Oxyalkylene Copolymers is reduction surface tension, soaks ground, and preferably anti-shrinkage cavity is carried
The flow leveling of high layer of ink, and froth breaking can be played.
