Abstract

The invention discloses a UV printing ink for silk-screen printing. The UV printing ink is characterized by being prepared from the following raw materials in parts by weight: 1 to 3 parts of organic pigment, 10 to 12 parts of neopentyl glycol diacrylate, 1 to 2 parts of aluminium isocaprylate, 2 to 3 parts of aluminium chloride, 1 to 2 parts of na-montmorillonite, 25 to 30 parts of epoxy acrylate, 1 to 2 parts of polyvinyl butyral, 5 to 8 parts of 1-hydroxy-cyclohexyl phenyl ketone, 10 to 12 parts of polyether acrylic ester, 6 to 9 parts of 1,6-HDDA, 10 to 12 parts of trimethylolpropane triacrylate, 13 to 17 parts of E-42 epoxy resin, 3 to 4 parts of metanilic methylamine, 1 to 2 parts of an accelerant M, 1 to 2 parts of a silane coupling agent KH-550 and 4 to 5 parts of an addition agent. The addition agent improves the toughness of the printing ink, enables the printing ink to be dispersed uniformly, and maintains the stability of the printing ink; the raw materials are rich in source, low in price, convenient to use and low in cost, the product quality is easy to control, the drying speed is high, and the energy consumption is low.

Description

UV ink and preparation method thereof for a kind of silk screen printing

Technical field

The present invention relates to a kind of ink and preparation method thereof, particularly UV ink and preparation method thereof for a kind of silk screen printing.

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.

Ultraviolet light polymerization (UV) ink refers under uviolizing, utilizes the UV-light of different wave length and energy to make ink film forming and dry ink.Utilize different UV spectrum, can produce different-energy, the monomer polymerization in different ink vehicles is become to polymkeric substance, so the look film of UV ink has good machinery and chemical property.The major advantage of UV ink has: (1) is without solvent; (2) rate of drying is fast, and power consumption is few; (3) good luster, bright in luster; (4) water-fast, resistance to solvent, wear resisting property is good.In UV ink, light trigger is a kind of light activated compound that is subject to, and after absorb light is shone, is excited into free radical, and energy is transferred to photosensitivity molecule or photocrosslinking agent, makes UV China ink that photocuring reaction occur.UV China ink has become a kind of more ripe ink technology at present, and its pollutant emission is almost nil.Except not containing solvent, UV China ink is also just like being difficult for scumming, and site is clear, the bright-coloured light of mass colour, the advantage such as chemical resistance is excellent, low-consuming.

Summary of the invention

The object of this invention is to provide UV ink and preparation method thereof for a kind of silk screen printing.

In order to realize object of the present invention, the present invention passes through following scheme implementation:

A kind of silk screen printing UV ink, raw material by following weight part is made: pigment dyestuff 1-3, neopentylglycol diacrylate 10-12, isocaprylic acid aluminium 1-2, aluminum chloride 2-3, na-montmorillonite 1-2, epoxy acrylate 25-30, polyvinyl butyral acetal 1-2,1-hydroxyl-ring base in the sixth of the twelve Earthly Branches phenyl ketone 5-8, polyether acrylate 10-12,1,6 hexanediol diacrylate 6-9, Viscoat 295 10-12, E-42 epoxy resin 13-17, amino methylamine 3-4, captax 1-2, silane resin acceptor kh-550 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, double pentaerythritol methacrylate 10-12, neopentyl glycol 5-7, p-tert-butyl benzoic acid 1-2, linking agent TAC2-3, polyisobutene 2-3, silane coupling agent KH560 1-2, 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.

Silk screen printing of the present invention UV ink, by following concrete steps, made: first add pigment dyestuff, neopentylglycol diacrylate, isocaprylic acid aluminium, aluminum chloride, na-montmorillonite, epoxy acrylate, polyvinyl butyral acetal, polyether acrylate, 1,6-hexanediyl ester, Viscoat 295, E-42 epoxy resin, an amino methylamine stirring and evenly mixing, be heated to 80-90 ℃, stir 25-35 minute; Then add all the other remaining components except 1-hydroxyl-ring base in the sixth of the twelve Earthly Branches phenyl ketone, stirring reaction 3-5 hour; Finally be cooled to 60-70 ℃, add 1-hydroxyl-ring base in the sixth of the twelve Earthly Branches phenyl ketone, 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; Raw material sources of the present invention are abundant, and cheap, easy to use, cost is low, and quality product is easily controlled, and rate of drying is fast, and power consumption is few.
