Description
Technical field
The present invention relates to a kind of UV ink, be specifically related to a kind of UV offset printing Halogen ink and preparation method thereof.
Background technology
UV offset printing Halogen ink, is to utilize ultraviolet light wave photosensitization, makes black film forming and dry.UV China ink mechanism dry and film forming is a kind of variation of chemistry.Utilize different ultraviolet spectrograms, produce different energy and by different prepolymers and different monomers, aggregate into polymkeric substance.So the look film of UV ink, has good mechanicalness and chemical.
UV offset printing Halogen ink is comprised of pigment, pre-(together) polymers, reactive thinner, light trigger and auxiliary agent conventionally, have curing speed soon, containing volatile solvent, odorless, the advantage such as non-stimulated, levelling good, not network blocking, water tolerance are strong, resistance to solvent scouring, be applicable to the printing of the materials such as metal foil paper, synthetic paper, compound gold and silver paperboard, compound laser paper, polychlorovinyl sheet material, polyester sheet, crystalline p p sheet, polyethylene sheets, iron plate.
In offset printing, use UV Halogen ink; can remove the color separation of dusting from; be conducive to the clean of printing environment; protection operator's health, has also avoided the trouble brought to post-press finishing owing to dusting, as the impact on glazing, overlay film; and can carry out line processing; improve operating environment, enhance productivity, shorten the time of delivery.
UV offset printing Halogen ink just solidifies and integrates after UV light source irradiates; pre-irradiation skinning not in ink tank not, can be not dry and hard in seal machine or version yet, and these characteristics can prevent the generation of ink skinning; solve trouble and worry when offset press is shut down, greatly reduced the waste of ink.
In addition, UV offset printing Halogen ink is in existing flexographic ink formula materials, to filter out not halogen-containing starting material as the material of formula.This has got rid of the existence of halogen ink from source.In some European ink standards, regulation demonstration can not contain halogen.From environmental angle, UV offset printing Halogen ink is mainly used in the printing of packing, environmentally friendly.
Summary of the invention
The object of the invention is to for the deficiencies in the prior art, a kind of UV offset printing Halogen ink is provided, this ink, containing any halogen, can not produce the carcinogenic substances such as Dioxins after burning yet, few, environmentally friendly on environment and human body impact.It is fast that this ink also has curing speed in addition, stable performance, and strong adhesion, stability in storage is strong, with the advantage such as the composite good dispersity of various pigment, is applicable to high-speed production, and production efficiency is high, only needs the extremely short time to anchor at substrate surface by complete drying.
Another object of the present invention is to provide the preparation method of above-mentioned a kind of UV offset printing Halogen ink.
