Description

A kind of ink for screen printing and preparation method thereof
Technical field
The invention belongs to advertising and printing fields, and in particular to a kind of ink for screen printing and preparation method thereof.
Background technique
Silk-screen, i.e. silk-screen printing, belong to porous printing, it and flat stamping, convex print, gravure are collectively known as four big printing sides Method.Porous printing includes stencil, engraves hole flower stencil, spraying decoration and silk-screen printing etc..The principle of porous printing is:Printing plate (paper membrane version Or produced in other editions version bases can be by the eyelet of ink) in printing, ink through hole version is made by certain pressure Eyelet be transferred on stock (paper, ceramics etc.), form image or text.
It by the extruding of scraper plate when printing, is transferred to ink on stock by the mesh of areas, is formed and original The same picture and text of original text.Screen printing apparatus is simple and convenient to operate, print, make a plate it is simple and low in cost, it is adaptable.Silk screen The wide common printed matter of printing application range has:Colored oil painting, pictorial poster, business card, binding and layout cover, product tag and printing and dyeing are spun Fabric etc..
Stencil duplicating is the simplest porous printing, starts from the late 19th century.It is this printing be on special paraffin paper, Paraffin paper picture and text edition is made by typewriter or stylus, is printed in paraffin paper version with ink roller, can just be managed on stock The printing effect thought.In porous printing, most widely used is silk-screen printing
Silk-screen printing is that silk fabrics, synthetic fabrics or wire mesh stretch tight on screen frame, using by hand carve paint film or The method of photochemistry plate-making makes screen printing forme.Modern screen printing technology is then using photosensitive material by photomechanical Method production screen printing forme (makes the silk screen hole through-hole of areas on screen printing forme, rather than the silk screen hole of areas is blocked Firmly) oil painting, etching, pictorial poster, business card, binding and layout cover, commodity packaging, product tag, printed textile, glass and metal etc. are flat Face carrier etc..
Ink for screen printing ink all when referring to using screen printing mode is known as ink for screen printing.
The prerequisite condition of folding plastic screen printing ink
1. ink should not dry conjunctiva on printing plate, and work as the requirement energy fixed drying rapidly for being printed onto surface of the stock, And there is good attachment fastness.
2. ink there should be loose, short, thin, sliding characteristic, coating is easy uniformly to guarantee ink on printing plate.It is small in stress Under conditions of be easy to net.It is required that printing picture and text are clear, there is no set-off phenomenon.
3. ink, when being coated on printing plate, viscosity, viscosity, the consistency of ink should have certain stability, to guarantee printing The consistency of quality and going on smoothly for printing.
4. after printing, the ink on printing plate will be convenient for cleaning up, to guarantee that printing plate can be reused.
5. guaranteeing that printing has certain colour saturation.For multicolour pattern, it is ensured that it has normal tone.
Existing ink for screen printing print unevenness is even, paints bad, and adhesion is poor, while being easy to fade under sunlight irradiation, Wear-resisting, waterproof and corrosion resistance are all relatively low.
