A kind of new ultra-violet photocuring silk screen pearl ink and preparation method thereof
Technical field
The present invention relates to a kind of ink and preparation method thereof, particularly a kind of new ultra-violet photocuring silk screen pearl ink and preparation method thereof.
Background technology
Silk screen printing is that silk fabrics, synthetic fabrics or wire cloth are stretched tight on screen frame, adopts manual method of carving paint film or photochemistry plate-making to make screen printing forme.Modern screen printing technique, to utilize sensitive materials by photomechanical method, to make the flat carriers such as screen printing forme (making the silk screen hole of picture and text part on screen printing forme is through hole, and the silk screen hole of non-graphic part is plugged) oil painting, etching, pictorial poster, business card, binding and layout front cover, commodity packaging, product tag, dyeing textile product, glass and metal etc.
Pearly pigment is as a kind of mode of printing of special-effect, rely on its unique pearliness, make printed matter surface produce graceful unique, the soft pleasing reward effect of looking, the characteristic simultaneously with anti-duplicating, there is certain antifalse effect, in numerous mode of printings, take the course of its own, become popular a kind of false proof and decorating printing technology.The application of pearly-lustre silk-screen ink can well embody the distinctive effect of pearly-lustre, in fields such as banknote, security, Package and labels, is widely applied.
Summary of the invention
The object of this invention is to provide a kind of new ultra-violet photocuring silk screen pearl ink and preparation method thereof.
In order to realize object of the present invention, the present invention passes through following scheme implementation:
A kind of new ultra-violet photocuring silk screen pearl ink, raw material by following weight part is made: pigment dyestuff 1-3, urethane acrylate 20-24, expanded graphite 1-2, swelling perlite powder 1-3, methyl ethyl diketone selenium 1-2,2,4,6-trimethylbenzoyl diphenyl phosphine oxide 5-8, oleum lini 3-4, silicone resin 12-14, tetrafluoroethylene 2-3, Viscoat 295 10-12,1173 light trigger 4-8, zinc naphthenate 2-4, diethylamine 1-2, auxiliary agent 4-5;
Described auxiliary agent is prepared from by the raw material of following weight part: nano diatomite powder 0.2-0.3, nano mica powder 0.2-0.3, Silane coupling agent KH550 1-2, linking agent TAC2-3, polyisobutene 2-3, sec.-propyl three (dioctylphyrophosphoric acid acyloxy) titanic acid ester 2-3, phenylformic acid amine 1-2, Viscoat 295 10-12, Tenox PG 2-3, coix seed oil 1-2; Its preparation method is by each mixing of materials, is heated to 60-70 ℃, and stirring reaction 30-40 minute, obtains.
New ultra-violet photocuring silk screen pearl ink of the present invention, by following concrete steps, made: first add pigment dyestuff, urethane acrylate, expanded graphite, swelling perlite powder, methyl ethyl diketone selenium stirring and evenly mixing, be heated to 80-90 ℃, stir 25-35 minute; Then add all the other remaining components except 1173 light triggers, stirring reaction 3-5 hour; Finally be cooled to 60-70 ℃, add 1173 light triggers, stirring reaction 40-50 minute, cooling after, grind and to obtain 20-40 μ m slurry, obtain.
The invention has the beneficial effects as follows: auxiliary agent of the present invention has improved the toughness of ink, make distributes ink even, and maintained the stability of ink; Between ink of the present invention and each stock, all there is good sticking power, snappiness, wear-resisting scratch resistance intensity, resistance to all kinds of solvent natures, can meet the requirement of silk screen printing.
Specific embodiments
Below by specific examples, the present invention is described in detail.
A kind of new ultra-violet photocuring silk screen pearl ink, by following weight part (kilogram) raw material make: pigment dyestuff 1, urethane acrylate 20, expanded graphite 1, swelling perlite powder 1, methyl ethyl diketone selenium 1,2,4,6-trimethylbenzoyl diphenyl phosphine oxide 5, oleum lini 3, silicone resin 12, tetrafluoroethylene 2, Viscoat 295 10,1173 light triggers 4, zinc naphthenate 2, diethylamine 1, auxiliary agent 4;
Described auxiliary agent by following weight part (kilogram) raw material be prepared from: nano diatomite powder 0.2, nano mica powder 0.2, Silane coupling agent KH550 1, linking agent TAC2, polyisobutene 2, sec.-propyl three (dioctylphyrophosphoric acid acyloxy) titanic acid ester 2, phenylformic acid amine 1, Viscoat 295 10, Tenox PG 2, coix seed oil 1; Its preparation method is by each mixing of materials, is heated to 60-70 ℃, and stirring reaction 30-40 minute, obtains.
New ultra-violet photocuring silk screen pearl ink of the present invention, by following concrete steps, made: first add pigment dyestuff, urethane acrylate, expanded graphite, swelling perlite powder, methyl ethyl diketone selenium stirring and evenly mixing, be heated to 80-90 ℃, stir 25-35 minute; Then add all the other remaining components except 1173 light triggers, stirring reaction 3-5 hour; Finally be cooled to 60-70 ℃, add 1173 light triggers, stirring reaction 40-50 minute, cooling after, grind and to obtain 20-40 μ m slurry, obtain.
The ink of gained, is used cross-hatching ox-hide tape stripping, draws compartment apart from 1mm, and 100% adheres to; Spirituous cotton balls is soaked in use, and 300 grams of pressure wipings 50 times, are as good as shape; Be soaked in salad oil (normal temperature) 8 hours, be as good as shape; Use is soaked with the cotton balls of salt solution, and 300 grams of pressure wipings 50 times, are as good as shape.
