Description
Technical field
The present invention relates to ink area, in particular to a kind of binder for water-based ink and corresponding water
Soluble ink.
Background technology
It is worsening with the living environment of the mankind, there is a growing awareness that " blue montains and green waters, exactly Kingsoft Yin Shan "
Importance, the severely afflicated area of print line cyclic border pollution already now, it prints the pollution source that ink is the sector again.
In view of severe Environmental Protection Situation, country has put into effect a series of laws and regulations in terms of environmental protections in succession, and passes through
Every professional standard clearly assert environment-friendly type printing ink.
Substitute traditional solvent-based ink imperative with water-based ink, make the dissolving carrier of ink, water-based ink with water
With significant environment-friendly advantage, its feature；It is nontoxic, non-ignitable not quick-fried, it is no disabled or transfinite it is using, may result in it is big
Gas pollutes or can trigger what atmospheric photochemistry acted on, may produce harm, poisonous and hazardous volatile organic to human body
The discharge of compound VOCs.
Water-based ink is uniquely to have passed through U.S. Food and Drug Administration (FDA) identification in current many ink kinds
The ink product available for food and medicine packaging field, there is the great market demand.
But water-based ink on the market still suffers from many defects at present, limits its industrialization process, especially water-based thin
The use of film gravure ink：
(1) water repelling property of water-based ink is difficult to get both with its solubility.
Current water-base gravure ink technology is in printing using link using single volatile dry film technique, cause
Make the dried printing layer of ink water-resistance of its printing poor, still can be dissolved again by moisture.In order to improve ink after printing
The water-fast water repelling property of layer, Printing ink producing enterprise all can passively add and using one in the final stage that ink finished product is processed
Divide the irreversible water-based emulsion of solubility property (oil-in-water film-forming resin lotion).Although improve the water-fast water-resistance of ink layer
Can, but the solubility for also resulting in ink at the same time is poor, directly contributes print of the water-based ink in printing using the easily stifled version of link
Brush failure and the difficult great quality defect of processing, make print production not to be normally carried out, hinder the industrialization of the product into
Journey.
(2) compared with organic solvent, the surface tension of water is higher, and specific heat capacity very big (the same heat of absorption, the temperature of water
Angle value change is small) slow drying speed, cause the drying property of water-based ink too slow, directly influence the production of printing enterprise into
Degree and production capacity.
(3) usually water-based ink is difficult to be really achieved certain anti-flammability, and there are security risk.
In view of this, it is special to propose the present invention.
The content of the invention
The first object of the present invention is to provide a kind of binder for water-based ink, because binder is the heart of ink
Dirty, the interior quality of binder has been largely fixed the end-use properties of ink.The binder and its manufactured oil
Black strong adhesive force, with good solubility during printing, prints and is not susceptible to stifled version failure during use, its printed product is again
With good water resistant, water resistance, ensure that print production can be carried out continuously for a long time from ink interior quality.
The second object of the present invention is to provide a kind of water-based ink, the strong adhesive force of the water-based ink, and when printing has
There is excellent solubility, make to be not susceptible to stifled version failure in printing process, its printed product has good water resistant, water resistance again
Can, ensure that print production can be carried out continuously for a long time from ink interior quality.
In order to realize the above-mentioned purpose of the present invention, spy uses following technical scheme：
A kind of binder for water-based ink, by weight, the binder include：Acrylic ester copolymerization tree
20~30 parts of fat, other 5~10 parts of macromolecule modified 10~30 parts of resin, 5~14 parts of aminating agent, 20~35 parts of water and ethanol.
Binder of the present invention：Including acrylic ester copolymerization resin, other macromolecule modified resins, aminating agent,
Water and ethanol, wherein acrylic ester copolymerization resin and other macromolecule modified resins mainly play binder, make in ink
Granules of pigments can be uniformly dispersed therein, and assign the certain mobility of ink and levelability, enable to be formed during printing
Even ink layer, and ink layer is produced certain attachment fastness with printing film base material.
Under normal circumstances, resin itself is difficult to be directly dissolved in water, of the present invention to prepare that (i.e. resin is molten in binder
Solution) during, the resin with carboxylic group is neutralized by using ammonia or amine substance, generates organic amine salt, amine salt is because of electricity
Water can be dissolved in from effect.And water can both make dissolving medium can make coalescents：The viscosity of i.e. adjustable ink, but it is adjustable
The color density of ink.The addition of ethanol can promote the abundant dissolving of resin in water, while can form azeotropic with water again, have
Beneficial to the volatilization of moisture, the printing rate of drying of ink is improved.
Binder of the present invention is the height based on acrylic acid esters co-polymer and other macromolecule class modified resins
Molecular material, using water or a small amount of alcohols solvent be dilution coalescents, using ammonium hydroxide or aminated compounds as neutralizer, and it is unique to select
Neutralization reaction new process it is polymerize, amination and self-emulsifying be modified, through the transparence viscous fluid obtained by above-mentioned reaction
Body is the binder that this is used for water-based ink.
Binder performance of the present invention is remarkable, the degree of branching and space structure unit of its molecule segment form short range aggregation
State multidimensional framework, affinity and dissolubility of the binder to moisture are improved while the attachment fastness to printed substrate is improved
And redissolve performance.Ink is conducive to moisture in oil to the close and distant degree of having of moisture made of making under the synergistic effect of coalescents
Disengaging layer of ink can quickly be escaped with single small molecule state in the drying process of ink print film forming, so as to accelerate the dry of ink
Dry speed, and make the drying of printing layer of ink more thorough.
