Description
Technical field
The present invention relates to the printing-ink field, relate to the compound special environment protection water color ink of a kind of plastic inner printing particularly.
Background technology
All the time, the pollution of printing ink is a problem the most serious in the Printing industry.World's printing ink annual production is above 3,000,000 tons.Solvent type ink on average accounts for 30%～40%, and the consumption of the annual organic solvent that brings because of printing ink in the whole world causes the huge wasting of resources up to more than 1,000,000 tons.Organic solvents such as the wherein frequent ethanol that uses, butylacetate, toluene, dimethylbenzene.The dry back overwhelming majority all can be eliminated, but lingering section still can work the mischief to human body, and long-term contact can make chapped skin, coarse, if infiltrate skin or blood vessel, can be with blood crisis people's blood cell and hematopoietic function, even may cause the human body chronic poisoning.In addition, heavy metal elements such as some mineral dye is leaded, chromium, copper, mercury, the certain toxicity of tool; The part pigment dyestuff contains biphenyl glue, and carcinogenic composition is arranged, and should forbid to use.The volatilization of solvent causes topsoil, and is bigger to the growth effect of each kind of plant, destroys the eubiosis, should cause the attention of the whole society.And heavy metal will cause sizable harm sometimes by plant absorbing if be absorbed by the body.
In a word, there is following shortcoming in conventional solvent type printing ink: 1) inflammable and explosive, produce the very big potential safety hazard of existence; 2) lot of V OC toxic organic compound is discharged in the air, polluted air; 3) solvent is a kind of toxic thing, has influence on the healthy of employee; 4) dissolvent residual, contaminated food products has influence on the consumer health; 5) a large amount of solvent evaporates, waste cause cost to increase.
Summary of the invention
The object of the present invention is to provide the compound aqueous ink special of a kind of plastic inner printing, to solve the above-mentioned problems in the prior art.The compound aqueous ink special of plastic inner printing among the present invention does not contain organic solvent, is environment-friendly type.
Technical scheme provided by the invention is as follows:
The compound aqueous ink special of a kind of plastic inner printing by weight, comprising:
The Tg value is aqueous acrylic emulsion 55-65 part of-40 ℃～25 ℃;
Aqueous color paste 25-35 part; With
Aqueous promoter 3-4 part
Wherein, this aqueous promoter comprises:

Preferably, described aqueous acrylic emulsion comprises composition A and composition B: this part emulsion is that the aqueous acrylic emulsion interworking by two kinds of different pieces of information characteristics forms, the interworking ratio of these two kinds of emulsions can change according to the variation of printing condition, print speed is fast, and the latex A that the interworking ratio is just high with the Tg value is occupied ratio more greatly.Help fast doing like this; Print speed is slow, and the emulsion B that the interworking ratio is just low with the Tg value occupies ratio more greatly, helps the good and difficult stifled version of print stream levelling like this.
Aqueous acrylic emulsion A:25～35 part, the type emulsion characteristic: the Tg value is 20 ℃～25 ℃, belongs to quick-dry type, molecular weight " 200000, molecular weight is big, and particle diameter is little, and particle distribution is tight, has outstanding bonding force.Solid content 45%～48%, acid number 50～60, water resisting property is good, viscosity 1000, good printing ink ink transfer and adaptability, pH value 8.5～8.9, density 1.05.
Aqueous acrylic emulsion B:30～35 part, the type emulsion characteristic: the Tg value is-30 ℃～-40 ℃, and film-forming temperature is low, stronger sticking power and preferable print stream levelling.Molecular weight " 200000, acid number 20～30, high gloss and transparency, excellent water resisting property, viscosity 500～800, good fluidity helps printing adaptability, pH value 8.5～8.9, density 1.05.
Pre-dispersed mill base fineness median size is 0.5～0.8 micron.This part is the important component part of decision ink color, can require to adjust the composition and the ratio of mill base according to distinct colors, allow it allot the ink of different colours and different look content, pre-dispersed mill base fineness median size is 0.5～0.8 micron, the ultra-fine complete coating that helps filming emulsion of particle diameter, make the molecule of look China ink perfect, therefore help to improve the glossiness and the flowability of ink.
Preferably, described aqueous wetting agent is that low molecular polyether (polyether) modification oxyethyl group (EO) is changed the poly-silicon alkyl oxide of dimethyl, has splendid wetting and diffusion effect.The surface tension of water can be dropped to 20.0～21.0 dyne/cm by 72 dyne/cm, thus close with the surface tension of printing element, improve sticking power and ink transfer that ink prints.
Preferably, in the described water-based pH value and dispersion agent be water soluble amino alcohol or its mixture, preferably, it is an active quantities greater than 85% water soluble amino alcohol mixture.In water color ink can in and the carboxylic acid group (～COOH), help pH value stability, improve glossiness, advantages such as good water resisting property and corrosion stability.
Preferably, described water-based flow agent is the polyphosphazene polymer dimethylsiloxane emulsion, plays excellent printing levelling effect, excellent increases sliding effect, improves scratch resistance and good preventing adhesiving effect
Preferably, described water-based quick dry agent is a high molecular zinc oxide emulsion, plays fast setting when allowing water color ink be transferred to printing element, and drying effect plays anti simultaneously and improves the wear resistance effect
Preferably, described water-based adhesion promoter is the alkoxyl group non-ionic compound, specialty is used for various plastic cement or metal substrate, has good dispersed and excellent sticking power promoter action, it can strengthen the adhesion strength of water color ink and plastics film, so that food pack ectonexine adhesive strength strengthens, make compound tensile strength reach 1.5-2 newton.
A kind of method for preparing the compound aqueous ink special of plastic inner printing may further comprise the steps:
The first step: solid propenoic acid resin is carried out synthetic chemistry reaction, copolymerization film forming according to different demand prescriptions in reactor.
Second step: the acrylic resin liquid and the wetting dispersing auxiliary of pigment dyestuff and 10% are ground dispersion, wetting through sand mill together, finally grind into about 30%～40% look content and pre-dispersed aqueous color paste with 25 seconds/3# cup/250C flowability.
The 3rd step: film-forming aqueous ACRYLIC EMULSION, pre-dispersed aqueous color paste and corresponding additive are required to put into the dispersion a mixing bowl according to different formula rates disperse to stir.Disperseing churning time is 30～45 minutes, and stirring velocity is 600～1000 rev/mins, and churning time is unsuitable long, and stirring velocity is unsuitable too fast, otherwise demulsifying phenomenon can occur.
The 4th step: the water color ink that will disperse stirring to finish dashes to be filled out, and packing becomes finished product.
Beneficial effect of the present invention is as follows: the 1) discharging of zero VOC toxic organic compound, and pollution-free to air; 2) no poisonous organic solvent volatilization has no adverse effects to pressman's health; 3) eliminate the inflammable and explosive hidden danger in working space, improved security.4) the printing comprehensive cost economizes 35% approximately than the traditional printing ink of solvent; 5) reduce with an organic solvent: as toluene, Tianna solution etc., for strategic reserves provides safeguard.6) no solvent residue, pollution-free to food product pack, healthy, green, safety; 7) printing of ink has high gloss, rub resistance, and counnter attack is sticking, high adhesive force, high temperature resistant, levelling property is good, saturated bright-coloured, the characteristics such as color development power is good of color.
