Description
Technical field
The present invention relates to a kind of pure water type cork paper gravure black ink and preparation method thereof, this ink is intaglio printing
Ink, belongs to technical field of packaging and printing.
Background technology
Cork paper, is commonly called as tipping paper, is used as the cigarette packaging material of cigarette filter rod outer package, belongs to extraordinary work
Industry paper using, it is typically by white tipping base paper printing.At present, the oil that a lot of cork paper printing houses use
Mostly ink is alcohol-soluble and ester dissolubility ink, containing substantial amounts of volatile organic solvent in these ink component, no
But atmospheric environment is polluted, and with after the ink printing cork paper of this type, cork paper surface can remain one
Quantitative volatile organic solvent, has certain hazardness to health.Along with people's environmental consciousness raising and
The understanding of the safety of used product is strengthened, it is desirable to cork paper printing-ink must be nontoxic, meets food and defends
Raw standard, therefore produces the Environmental-protection water-based ink without volatile organic solvent imperative.
Summary of the invention
It is an object of the invention to provide a kind of pure water type cork paper gravure black ink and production method thereof, this ink is not
Use organic solvent, for pure water type ink, safe and nontoxic, health, environmental protection.Pure water type cork paper gravure is black
Ink uses intaglio printing mode, and for cork paper printing, the good leveling property of ink, rate of drying is fast, its printing
Velocity interval is 100～200m/min.Printing quality is good and production cost is relatively low.Safety index VOC detection meets
GB GB/T 26395-2011, heavy metal analysis meets EN71-3, can meet the standard of food safety and sanitation.Can
Substitute solvent type ink for cork paper printing.
In order to reach object above, the present invention takes techniques below scheme:
A kind of pure water type cork paper gravure black ink, is mixed with by white carbon black, resin, deionized water, auxiliary agent
Arriving, it includes following composition and weight proportion: white carbon black 21～26 parts, water-borne acrylic resin 33～37 parts, go
Ionized water 35～40 parts, defoamer 1～2 parts, dispersant 1～2 parts and surfactant 0.5～1.5 parts.
Preferably, component and the weight proportion of ink is: white carbon black 23～25 parts, water-borne acrylic resin 34～36 parts,
Deionized water 36～38 parts, defoamer 1.3～1.7 parts, dispersant 1.3～1.7 parts and surfactant 0.8～1.2 parts.
White carbon black has less particle diameter, and oxy radical content is higher and oil absorption is relatively low, has higher blackness and relatively
Strong tinting strength, tinting power, higher glossiness and preferable wettability, relatively low viscosity and the feature of bigger fluidity.
Described water-borne acrylic resin is the s-2916 resin that east subfamily power company produces, and this resin is by modification
Process, preferable to the wettability of white carbon black, there is preferable wearability and film property simultaneously, the grinding of ink can be met
Performance and filming performance, and use the ink containing s-2916 resin to print on cork paper, can significantly improve
The rate of drying of ink and attachment fastness.
Described defoamer is polyethers oxosilane co-polymer.
Described dispersant is the aqueous copolymers solution containing pigment affinity groups, and concentration i.e. active matter content is 40 weights
Amount %.
Described surfactant is polysiloxane-polyether copolymer.
The preparation method of above-mentioned pure water plastic gravure black ink, comprises the steps:
(1) white carbon black, water-borne acrylic resin, deionized water, defoamer, dispersant and surfactant are pressed
Weigh according to described proportioning and mix, be allowed to mix homogeneously with machine mixer stirring, be subsequently poured into sand milling machine cavity
In, use sand mill grinding distribution, until particle diameter is less than or equal to 2 microns, stop grinding；
(2) 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 ink is 20～60min, and stir speed (S.S.) is 400～600r/min；
Milling time is 30～120min, and grinding rate is 1800～2000r/min.
White carbon black acts primarily as coloration in ink, and water-borne acrylic resin is one of main component in ink, rises
The effect of disperse black carbon, and make ink form uniform thin layer after printing, it is formed with some strength after drying
Film layer, shields to pigment so that it is be difficult to come off.Dispersant is interfacial agent, can reduce between liquid/solid
Interfacial tension, strengthen the lyophily of pigment, improve mechanical lapping efficiency, and dispersant adsorption is in surface of pigments
Upper composition charge effect or space steric effect, prevent white carbon black flocculating sedimentation, makes ink be in steady statue.Due to
Ink is alkaline system, easily produces bubble when mechanical agitation and grinding, affects the efficiency and effect ground, therefore
Defoamer should be added in ink system.When printing, it is desirable to the surface of the surface tension cork paper to be less than of ink
Tension force, such ink has preferable wettability and adhesive force, therefore needs to add surfactant, reduces cork paper
The surface tension of ink system.
The ink of the present invention has good printability, and its particle diameter is 0.5～2 μm, uses 3#The test of Cai's grace cup is viscous
Degree is 10～20s.
The ink of the present invention has good printing quality, bright-coloured with its product color printed, and glossiness is high, stream
Levelling is good, and print speed printing speed scope is 100～200m/min.
The ink of the present invention uses intaglio plate shallow version printing, can save the ink usage of 1/4～1/3 (weight).
The resin that the present invention uses is water-soluble resin, dissolubility in water and preferable to the wettability of pigment.And
And the present invention uses deionized water to make solvent, do not use any organic solvent, reduce the pollution to atmospheric environment, print
Brush only dilutes with deionized water, and uses shallow version printing, reduce cost, safety and environmental protection, safety index
VOC detection meets GB GB/T 26395-2011, and heavy metal analysis meets EN71-3.The pure water that the present invention produces
Type cork paper gravure black ink is applicable to intaglio printing, and the production technology of ink is simple, good leveling property, printing speed
Degree can reach 100～200m/min, and printability and printing performance are good.General water color ink is easiest to asking of appearance
One of topic is that rate of drying is very slow (such as 50-60m/min), it is impossible to reach the requirement of printer.And the present invention passes through
Raw-material combination and counterweight, solve this problem well.
