Description
Technical field
The present invention relates to print film field, particularly to a kind of water color ink print film and preparation method thereof.
Background technology
The existing printing ink of China is petroleum distillate, benzene and its derivative or organic solvent of ketone type ink,
In production process, healthy to operating worker causes harm, if as the printing-ink of packaging for foodstuff, little molecule has
Migration and the infiltration of machine thing will produce impact to consumer health.
Water color ink is referred to as water-based ink, water solublity or water dispersible macromolecule resin are link stuff, organic pigment, molten
Agent water and related auxiliaries composition.Water color ink differs primarily in that with oil-based ink, solvent type ink with organic solvent as solvent,
And water color ink with water (45%～50%) as solvent, therefore water color ink is extremely low with VOC content, toxicity is little and nonflammable etc. excellent
Put and by bigger favor, develop rapidly in flexible package and packaging for foodstuff printing industry as " green printing " material.But it is existing
The stability of some water color inks is not so good as solvent type ink, and resistance to migration is poor, and the goods printed easily migrate, impact printing
The printing effect of film.
The Chinese patent of Application No. CN105294973A discloses one group of high color density resistance to migration aqueous polyurethane-type combustion
Material and preparation method thereof, is improved the raw material of water color ink, improves the resistance to migration of water color ink.
But, the resistance to migration of print film to be improved, on the one hand need to improve the resistance to migration of water color ink, on the other hand
Needing to improve on the raw material of plastic sheeting, solvent ink is suitable for almost all of thin film of printing, and water color ink is not
Being easily applied to print general thin, owing to water color ink surface tension is high, the additive of thin-film material easily separates out surface, fall
The surface tension of low film surface, thus reduce the compatibility between water color ink and thin film, printing effect can be affected.
Summary of the invention
The technical problem to be solved is: provides a kind of water color ink print film and preparation method thereof, solves water
Property ink printing on thin film, poor compatibility, the problem easily migrated.
In order to solve above-mentioned technical problem, the technical solution used in the present invention is: provide a kind of water color ink print film, institute
State water-based printing film and include water color ink layer and thin layer；
The water color ink of described water color ink layer is formed by the preparation of raw material of following weight portion: 50 parts of water, binder 30 parts,
Pigment 15 parts, auxiliary agent 2 parts, anti-wear agent 1 part, ammonia derivatives 2 parts；Described binder is water-based polyurethane latex；
The thin film of described thin layer is formed by the preparation of raw material of following weight portion: high-foaming EVA particle 20-40 part, once
Foaming EVA particle 60-80 part, EEA particle 30-40 part, double (2,2,6,6 tetramethyl-4 piperidyl) SA ester 0.2 part, phosphorous
Acid three (2,4-di-tert-butyl-phenyl) ester 0.2 part, γ-methacryloxypropyl trimethoxy silane 0.2 part, tricresyl phosphate are pungent
Ester 0.2 part, calcium stearate 0.2 part.
The beneficial effects of the present invention is: the formula of the water color ink layer of design water color ink print film, water color ink prints
The water color ink binder of brush film uses water-based polyurethane latex, strengthens ink and adhesion of thin film, makes water color ink stable
Property is higher, makes water color ink have higher resistance to migration；Design the formula of thin layer simultaneously, make thin layer be applicable to print water
Property ink, improve the compatibility of water color ink and thin film, not plasticizer-containing in thin layer raw material, there is not plasticizer extraction asking
Topic, adds EEA particle in formula, is effectively improved toughness and the heat stability of thin film, without opening agent in formula, prevent opening
Agent and low molecule material separate out film surface and affect water color ink stability on thin film.By improve water color ink layer and
The formula of thin layer, makes water color ink layer adhesive force on thin layer more than 95%.
