Description
Technical field
The present invention relates to ink-printing techniques field, more particularly to a kind of water-based flexographic ink.
Background technology
Flexible version printing (flexography), abbreviation flexographic printing, refer to pass using flexographic plate, by anilox roller
Pass a kind of mode of printing that ink applies print.Flexographic printing, printing plate typically use thickness 1-5mm photopolymer plate.Ink point three
Major class, it is water-based ink, alcohol-soluble printing ink, UV ink respectively.Due to ink used in flexographic printing meet it is green, at present
Food, packages printing are largely used to, is had a extensive future.Flexographic printing belongs to convex print type.
Flexographic printing, hectographic printing, intaglio printing and silk-screen printing are most common four big mode of printings in the world, they
With their own characteristics, it is each has something to recommend him.In the flourishing country of the printing industries such as America and Europe, flexographic printing have developed rapidly, packages printing from
It is changed into based on gravure and offset printing based on flexographic printing, about 70% packaging material uses flexographic printing.
In China, development and people's living standards continue to improve with commodity economy, package printing industry is also positive
High-grade, fine, multi items direction to develop.But offset printing and the market share shared by gravure are quite big, and flexographic plate is printed on
The starting in China is then than later, particularly in terms of the printing of expensive goods.With the continuous application of new technology, flexographic printing is
Through having made significant headway, product quality directly chases after offset printing and gravure, is provided with the great market competitiveness.
Compared with gravure, offset printing and traditional convex print, flexographic plate mode of printing has oneself salient feature:Cost
It is low；Equipment is simple；Efficiency high；It is in extensive range；Quality is good；Environmental protection；And printed matter level is abundant, in bright gay color, visual effect
It is good, it is particularly suitable for the requirement of packages printing.
Ink is mostly solvent typically by the material compositions such as link stuff, pigment, filler, solvent, auxiliary agent, traditional ink
Ink often containing aromatic compounds such as toluene, dimethylbenzene, can cause air pollution during use, and volatilize carcinogenic substance
Matter, the health of staff is damaged.Water-based ink is a kind of ink type of green non-pollution.In Chinese patent
The aqueous ink of CN105820651A middle fingers nonflammable, model stability, does not corrode sheet material because its is cheap, simple to operate
Outer packing especially suitable for video, beverage, cigarette etc. is printed.
But cause that the tack of water-based ink ink is poor, ink transfer is undesirable, ink because the surface tension of water is higher
Water-resistance, the moisture-proof frictional behaviour for printing finished product are poor；Paper contraction is easily caused, limits the scope of application of water-based ink.
The content of the invention
It is poor to solve water-based ink wearability, tack, the undesirable technical problem of ink transfer, propose a kind of aqueous flexible plate
Ink.
The technical scheme is that；
A kind of water-based flexographic ink, 10-20 parts water-based acrylic resin, 20-30 part aqueous acrylamide yogurts are included according to parts by weight
Liquid resin, 20-30 parts pigment, 7-16.5 parts water-soluble additive and 10-20 part cosolvents.
The water-based flexographic ink of the present invention is helped by water-base resin link stuff, inorganic pigment, water-soluble additive and a part
The uniform slurry like material of the material composition such as agent and water.The water-base resin binder of use is by water-based acrylic resin（Water-soluble）And
Aqueous acrylic emulsion resin（Water-dispersion type）Deng composition, water-base resin is most important composition in water-based ink, and its composition is straight
Connecing influences the attached function of ink, rate of drying, preventing stick dirty performance etc.；Ink and ink transfer are also influenceed simultaneously, to ink
Provide necessary transfer performance.The preferably low VOC of ink of the present invention, the water-base resin of low smell etc..Water-soluble additive is one
The mixture of kind or many kinds of substance.Cosolvent is needed to use to improve the water solubility of resinae.Cosolvent can be water and second
Alcohol, mainly dissolving resin, adjust the viscosity and rate of drying of ink.
Preferably, water-based ink includes 15 parts of water-based acrylic resins, 28 parts of aqueous acrylic emulsion trees according to parts by weight
Fat, 25 parts of pigment, 12 parts of water-soluble additives and 15 parts of cosolvents.
Preferably, pigment is the one or more in rutile titanium white powder, iron oxide, iron hydroxide, pearl essence, carbon black.
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, colour saturation sense
By force, the pigment of use is good from chemical stability, the high inorganic pigment of tinting strength, tinting power.
Preferably, pigment is iron hydroxide.
Preferably, aqueous promoter is the one or more in dispersant, defoamer, slipping agent, drying retardant and diluent.
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.Retarding agent is used for the dry speed for suppressing water-based ink
Degree, prevents that ink is solid in anilox roll, reduces scumming etc..The mainly abundant ink " skeleton " of slipping agent, improves printing levelling,
Increase color saturation etc..Diluent is the color for subtracting light water-based ink, can also be used as a kind of polishes, improves water-based ink
Brightness.Some waxs are also added to increase its wearability in other water-based ink.
Preferably, aqueous promoter fraction by weight is smooth comprising 0.5-2 parts dispersant, 0.5-1.5 parts defoamer, 3-5 parts
Agent, 3-8 part drying retardants.
Preferably, dispersant is dimethyl silicone polymer, and defoamer is silicone emulsion, and slipping agent is Tissuemat E, slow curing
Agent is propane diols.
Preferably, aqueous promoter fraction by weight is smooth comprising 0.5-2 parts dispersant, 0.5-1.5 parts defoamer, 3-5 parts
Agent, 3-8 parts drying retardant and 2-3.5 part diluents.
Preferably, diluent is in parts by weight comprising 10-20 parts water-based acrylic resin, 40-50 part water soluble acrylic acid trees
Fat, 3-5 parts Tissuemat E, 0.5-1.5 parts silicone emulsion, 10-20 part ethanol.
Preferably, aqueous promoter also includes talcum powder, and the parts by weight of the talcum powder are 8-15 parts.
The present invention uses water-based acrylic resin and aqueous acrylic emulsion resin effectively to strengthen ink as binder
Tack, improve its preventing stick dirty and ink transfer.The low VOC of water-base resin, low smell.The auxiliary agent for increasing proper ratio is beneficial to increase
The mobility of inking up.
