Agent 1.3～1.7 parts and surfactant 0.7～1.3 parts；Wherein composition and the weight proportion of polyvinyl alcohol water solution is:
Polyvinyl alcohol 7～9 parts, deionized water 91～93 parts.
Described blue or green pigment is phthalocyanine blue, and pigment has preferable hydrophily, higher tinting strength, tinting power and transparency.
Described water-borne acrylic resin is good to the wetability of blue or green pigment, the good dispersion in water；Described aqueous third
Olefin(e) acid resin can be selected for the AZR resin that atropic hereby company in Tianjin produces, and feature is exactly that the wetability to pigment is good,
Good dispersion in water, wearability is good, and good fluidity can prevent the flocculating setting of ink.
Described is let down resin good film-forming property；The described resin that is let down may select what east subfamily power company produced
S-2919 resin (water-borne acrylic resin).This resin passes through modification, has good filming performance, and use contains
There is the ink of s-2919 resin at print upon plastic materials, can significantly improve rate of drying and the attachment fastness of ink.
Described defoamer is polyethers oxosilane co-polymer.
Described dispersant has two kinds, and a kind of is the aqueous copolymers solution containing pigment affinity groups, concentration i.e. active matter
Content is 40 weight %, a kind of be surfactant with the mixture of the polymer containing pigment affinity groups water-soluble
Liquid, concentration i.e. active matter content is 35 weight %.Different dispersants is different to the suction-operated of blue or green pigment,
Use both dispersants simultaneously, there is synergistic effect, make system concurrently form charge effect and sterically hindered effect,
Prevent blue or green pigment flocculation sedimentation, make dispersion more stable.
Described surfactant has two kinds, and one is polysiloxane-polyether copolymer, and one is oxosilane economic benefits and social benefits circle
Face activating agent.The surface tension of water color ink is higher, and the surface tension of base material plastics is well below water color ink
Surface tension, well spreads on plastics to ink, it is necessary to make the surface tension surface less than plastics of ink
Tension force.Both surfactants are used to produce cooperative effect so that it is to become efficient surfactant, can be well
Reduce the surface tension of ink.
The preparation method of above-mentioned pure water plastic gravure green grass or young crops ink, comprises the steps:
(1) by green grass or young crops pigment, water-borne acrylic resin, deionized water, defoamer, dispersant and surfactant
Weigh mixing according to described proportioning, be allowed to mix with machine mixer stirring, be subsequently poured in sand milling machine cavity,
Use sand mill grinding distribution, until particle diameter is less than or equal to 2 microns, stops grinding, obtain Ji Mo；
(2) by polyvinyl alcohol deionized water dissolving, heating stirs, and obtains polyvinyl alcohol water solution；
(3) by base ink, be let down resin, deionized water and polyvinyl alcohol water solution according to described proportioning weigh mixing,
It is allowed to mix with machine mixer stirring；
(4) scattered sample is sent into control laboratory, the indices of detection ink and performance are qualified through inspection
Rear filtration, packaging.
In step (1), the mixing time of described base ink is 20～60min, and mixing speed is 400～600r/min,
Milling time is 30～120min, and grinding rate is 1800～1900r/min.
In step (2), the mixing time of described polyvinyl alcohol water solution is 20～60min, and mixing speed is
800～1000r/min, temperature is 50～90 DEG C.
In step (3), the mixing time of described blending ingredients is 20～60min, and mixing speed is
400～600r/min.
In base ink, blue or green pigment acts primarily as coloration in ink, and water-borne acrylic resin is the main one-tenth in ink
/ mono-, play the effect of the blue or green pigment of dispersion, tool has good wearability, and is formed when mechanical agitation and grinding and has
The fluid of certain viscosity.Dispersant is interfacial agent, can reduce the interfacial tension between liquid/solid, strengthens pigment
Lyophily, improves mechanical lapping efficiency, and dispersant adsorption constitutes charge effect and space bit on the surface of the pigment
Inhibition effect, prevents blue or green pigment flocculation sedimentation, makes ink be in stable state.Owing to ink is alkaline system, at machine
Easily produce bubble, the efficiency of impact grinding and effect when tool stirring and grinding, therefore should add in ink system and disappear
Infusion.When printing, it is desirable to the surface tension of the surface tension cork paper to be less than of ink, such ink is to plastics
There are preferable wetability and adhesive force, therefore need to add surfactant, reduce the surface tension of ink system.
Using s-2919 resin when being let down, ink can form uniform thin layer after printing, is formed certain after drying
The film layer of intensity, shields to pigment so that it is be difficult to come off.Use polyvinyl alcohol, be to increase ink
Wetability and attachment fastness to plastics.The wearability extreme difference of resin, the easy breakdown of emulsion when grinding, add in base ink
It is let down resin, it is possible to reduce resin is destroyed, plays the performance of resin most possibly.
Ink of the present invention has good printability, and its particle diameter is 0.5～2 μm, and viscosity is 10～20s.
This ink has good printing quality, bright-coloured with its product color printed, and glossiness is high, uses adhesive tape
Method test attachment fastness is 93%～100%, and print speed printing speed scope is 100～200m/min.
This ink uses intaglio plate shallow version printing, can save 1/4～1/3 (weight) of ink usage.
Meanwhile, this ink safety index VOC detection meets GB GB/T 26395-2011, and heavy metal analysis meets
EN71-3。
The resin that ink of the present invention uses is water-soluble resin, dissolubility in water and to the wetability of pigment relatively
Good.And use deionized water to make solvent, do not use any organic solvent, reduce the pollution to atmospheric environment, print
Brush only dilutes by deionized water, and uses shallow version printing, reduction cost, safety, health, environmental protection,
Safety index VOC detection meets GB GB/T 26395-2011, and heavy metal analysis meets EN71-3.The present invention
The pure water plastic gravure green grass or young crops ink produced is applicable to intaglio printing, it is adaptable to the plastic sheetings such as BOPP, PET
In print and table print, the production technology of ink is simple, and adhesive force is good, and rate of drying is fast, good leveling property, print speed printing speed
Can reach 100～200m/min, printability and printing performance are good.General water color ink is easiest to produced problem
One of be that rate of drying is very slow (such as 50-60m/min), it is impossible to reach the requirement of printing machine.And the present invention is by former
The combination of material and counterweight, solve this problem well.
