Description
Technical field
The present invention relates to ink-printing techniques field, more particularly to a kind of water-based ink.
Background technology
Maximum difference is with solvent-based ink, and the solvent that water-based ink uses is water and fraction ethanol, almost without
VOC produces, and VOC discharge, air conservation is greatly reduced.Solvent-based ink can be completely eliminated in it
In harm of some noxious materials to human body and the pollution to package goods.Will particularly suitable for sanitary conditions such as food, medicines
Seek strict Packaging Printing Product.The requirement of water-based ink compliance environmental protection, product have nontoxic, non-corrosiveness, nonirritant gas
Taste, non-ignitable, not quick-fried, security is good, printing adaptability is good, stable performance.It is presently the most popular in water-based ink to surely belong to adagio
Water-based ink.Initially, adagio water-based ink is served only for the printing of paper bag, and later use range gradually expands.In the U.S., now
The use of adagio water-based ink is largely focused on packages printing field, accounts for 85%, such as various plastic foils, metal foil class, paper
Plate, decoration wrapping paper, glass cloth, brown paper etc..The use of these packages printing ink, include those matrix directly printed
(i.e. table prints), and the matrix (being printed in i.e.) of composite construction is made.Remaining is then used for books and periodicals, commercial advertisement and special printing etc.
With.The adagio water-based ink in the U.S., 2/3rds be aqueous flexographic printing ink, and remaining is then solvent type.At present, it is soft in China
Plate water-based ink is also constantly expanding its application field and market share.Because adagio water-based ink is in many different substrates
On be attained by good printing quality substantially.Flexographic presses, as a result of the metal anilox roll ink supply system of short ink
System, ink amount is easily controlled, and automated procedures are higher, and therefore, the operating technology of printing is simpler than convex print, flat stamping.
Solvent used in the liquid ink of this kind low viscosity (100-250cps) is to dissolve the polymerization in ink
Based on thing.Its used typical solvent is water and alcohol, and a small amount of glycol ether, tenth of the twelve Earthly Branches purport and aliphatic hydrocarbon.Its
Film forming polymer is poly- phthalein amine, nitrocellulose, rosin, lac and propylene vinegar class etc., is typically used in these polymer
One kind removes modified another kind (such as：Nitrocellulose can increase heat resistance；Poly- phthalein amine can increase gloss and pliability).In majority
In adagio water-based ink, typically using two or more polymer or solvent, to obtain the balance in performance.Adagio water-based ink
Typically contain the different composition of 7-15 kinds in system, these compositions constitute pigment used in typical adagio water-based ink,
Total class component of polymer, solvent and additive.
The water-based ink of film is expected in printing in the prior art, because the surface tension of hydrone causes greatly water-based oil very much
Black difficult moistening, slow-drying, tack, low in glossiness, wearability is undesirable, and the stability of ink is not high.
The content of the invention
The present invention is the solution technical problem that water-based ink slow-drying, tack and wearability are not desired in the prior art,
It is proposed a kind of water-based ink.
A kind of water-based ink of the present invention, 15-26 parts Styrene-acrylic copolymer, 18-25 are included according to parts by weight
Part cosolvent, 0.18-0.24 parts auxiliary agent, 15-35 parts pigment and 7-13 part inserts.
Water-based ink using water as primary solvent, by aqueous polymer as binder and pigment, various auxiliary agents and
Inserts etc. is through designing, allocating, a kind of novel ink that attrition process forms.The present invention is made with Styrene-acrylic copolymer
For binder, link stuff composition directly affects the attached function of ink, rate of drying, preventing stick dirty performance etc.；Oil is also influenceed simultaneously
Black gloss and ink transfer, necessary transfer performance is provided to ink.Styrene benzene ring structure has certain rigidity, can improve
The regularity of polymer molecular structure, so as to improve the glass transition temperature of polymer, be advantageous to improve the hardness after resin film forming
And resistance to elevated temperatures, while improve adhesive force of the ink on paper.
Water-based ink in the present invention includes 20 parts of Styrene-acrylic copolymers, 20 parts of cosolvents, 0.2 according to parts by weight
Part defoamer, 25 parts of pigment and 10 parts of inserts；
Or 15 parts of Styrene-acrylic copolymers, 18 parts of cosolvents, 0.18 part of auxiliary agent, 15 parts of pigment and 7 parts of inserts；
Or 26 parts of Styrene-acrylic copolymers, 25 parts of cosolvents, 0.24 part of auxiliary agent, 35 parts of pigment and 13 parts of inserts.
Pigment in ink is titanium dioxide, the one or more in di-iron trioxide, iron hydroxide, such as pigment is two
Titanium oxide, pigment are titanium dioxide, and pigment is iron hydroxide.
Pigment is the present-color material of water-based ink, gives the particular color of ink one.To make trace beautiful in colour in flexo, color
Saturation sense is strong, and the pigment of use is good from chemical stability, the high inorganic pigment of tinting strength, tinting power.The good stability of inorganic pigment can
It is colour-fast for a long time to ensure the persistence of ink color.
Preferably, the pigment is titanium dioxide.
Preferably, the cosolvent is ethanol.
Preferably, the inserts is one or both of talcum powder, kaolin.
Talcum powder, kaolin improve printing levelling, increase color as the mainly abundant ink " skeleton " of feature inserts
Saturation degree etc..Talcum powder can also improve the wearability of ink to a certain extent while the lubricity of ink is increased.
Preferably, the auxiliary agent is organosilicon auxiliary agent.
It is further preferred that the organosilicon auxiliary agent is octamethylcy-clotetrasiloxane.
Because water-based ink is a kind of soap composition, bubble is also easy to produce in use, therefore to add silicone oil material conduct
Defoamer, to suppress and eliminate bubble, while improve the transfer performance of ink.If octamethylcy-clotetrasiloxane is as defoamer.
Preferably, auxiliary agent also includes diluent, and the diluent includes 10-20 part water soluble acrylic acid trees in parts by weight
Fat, 40-50 parts water-based acrylic resin, 3-5 parts Tissuemat E, 0.5-1.5 parts silicone emulsion, 10-20 part ethanol.
It is further preferred that the diluent is in parts by weight comprising 15 parts of water-based acrylic resins, 46 parts of aqueous acrylamides
Acid resin, 4 parts of Tissuemat Es, 0.8 part of silicone emulsion, 10-20 part ethanol.
The different scope of application has different requirements to the depth of color, can be subtracted by adding diluent in auxiliary agent
The color of light water-based ink, a kind of polishes can be also used as, improve the brightness of water-based ink.
Styrene-acrylic copolymer and the inserts of approrpiate wts part are added in the present invention, increases the attached of water-based ink
The property and film forming, improve printing levelling, increase color saturation, the correct proportioning of cosolvent improves the rate of drying of ink.
