Description
Technical field
The present invention relates to blue or green ink of a kind of pure water type cork paper gravure and preparation method thereof, this ink is gravure printing ink, belongs to technical field of packaging and printing.
Background technology
Cork paper, is commonly called as tipping paper, is to be used as the cigarette packaging material of cigarette filter rod outer packaging, belongs to special industrial paper using, and it is normally by white tipping base paper printing.At present, the ink that a lot of cork paper printing houses adopt be mostly alcohol dissolubility with the ink of ester dissolubility, containing a large amount of volatile organic solvents in these ink component, not only atmospheric environment is polluted, and with after the ink printing cork paper of this type, cork paper surface can remain a certain amount of volatile organic solvent, has certain hazardness to HUMAN HEALTH.Raising along with people's environmental consciousness and the understanding to the security of used product strengthen, and require that cork paper printing-ink must be nontoxic, meet food hygienic standard, the Environmental-protection water-based ink therefore produced not containing volatile organic solvent is imperative.
Summary of the invention
The object of this invention is to provide the blue or green ink of a kind of pure water type cork paper gravure and production method thereof, this ink not with an organic solvent, is pure water type ink, safe, nontoxic, health, environmental protection.The pure water type cork paper blue or green ink of gravure adopts intaglio printing mode, for cork paper printing.The good leveling property of ink, rate of drying is fast, and its print speed scope is 100 ~ 200m/min.Printing quality is good and production cost is lower.Safety index VOC detects and meets GB GB/T 26395-2011, and heavy metal analysis meets EN71-3, can meet the standard of food safety and sanitation.Alternative solvent type ink is used for cork paper printing.
In order to reach above object, the present invention takes following technical scheme:
A kind of pure water type cork paper blue or green ink of gravure, be mixed with obtained by blue or green pigment, resin, deionized water, auxiliary agent, it comprises following composition and weight proportion: blue or green pigment 23 ~ 28 parts, water-borne acrylic resin 34 ~ 38 parts, deionized water 32 ~ 37 parts, defoamer 1 ~ 1.5 part, dispersion agent 1 ~ 2 part and 1 ~ 1.5 part, tensio-active agent.
Preferably, the composition of ink and weight proportion are: blue or green pigment 24 ~ 26 parts, water-borne acrylic resin 35 ~ 38 parts, deionized water 33 ~ 36 parts, defoamer 1 ~ 1.4 part, dispersion agent 1.4 ~ 1.8 parts and 1.1 ~ 1.3 parts, tensio-active agent.
Described blue or green pigment is phthalocyanine blue, and pigment has good wetting ability, higher tinting strength and transparency.
Described water-borne acrylic resin is the s-2916 resin that east subfamily power company produces, this resin passes through modification, better to the wettability of blue or green pigment, there is good wear resistance and film-forming properties simultaneously, nonferromagnetic substance and the film forming properties of ink can be met, and use the ink containing s-2916 resin to print on cork paper, rate of drying and the attachment fastness of ink can be improved significantly.
Described defoamer is polyethers siloxane co-polymer.
Described dispersion agent is the aqueous copolymers solution containing pigment affinity groups, and concentration and active matter content are 40 % by weight.
Described tensio-active agent is polysiloxane-polyether copolymer.
The preparation method of the blue or green ink of above-mentioned pure water plastic gravure, comprises the steps:
(1) blue or green pigment, water-borne acrylic resin, deionized water, defoamer, dispersion agent and tensio-active agent are mixed according to described proportioning weighing, stir with machine mixer and make it to mix, then pour in sand mill chamber, use sand mill grinding distribution, until particle diameter is less than or equal to 2 microns, stop grinding;
(2) scattered sample is sent into testing laboratory, detect indices and the performance of ink, through filtering after the assay was approved, packing.
In step (1), the churning 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.
Blue or green pigment is main in ink plays coloration, and water-borne acrylic resin is one of main component in ink, plays the blue or green pigment of dispersion; and make ink form uniform thin layer after printing; be formed with the rete of some strength after drying, pigment is shielded, make it be difficult to come off.Dispersion agent is interfacial agent, Gu can reduce liquid/between interfacial tension, strengthen the lyophily of pigment, improve mechanical lapping efficiency, and dispersant adsorption forms charge effect or space steric effect on the surface of the pigment, prevent blue or green pigment flocculation sedimentation, make ink be in steady state.Because ink is alkaline system, very easily produce bubble when mechanical stirring and grinding, the efficiency of impact grinding and effect, therefore should defoamer be added in ink system.When printing, require that the surface tension of ink will lower than the surface tension of cork paper, such ink has good wettability and sticking power to cork paper, therefore needs to add tensio-active agent, reduces the surface tension of ink system.
Ink of the present invention has good printability, and its particle diameter is 0.5 ~ 2 μm.Adopt 3
#cai's grace cup tested viscosity is 10 ~ 20s.
Ink of the present invention has good printing quality, and bright-coloured with the product color of its printing, glossiness is high, good leveling property, and print speed scope is 100 ~ 200m/min.
Ink of the present invention uses the shallow version printing of intaglio plate, can save the ink usage of 1/4 ~ 1/3 (weight).
The resin that the present invention adopts is water soluble resin, the solvability in water and better to the wettability of pigment.And the present invention adopts deionized water to make solvent, do not use any organic solvent, reduce the pollution to atmospheric environment, only dilute with deionized water in printing, and use shallow version printing, reduce costs, safety and environmental protection, safety index VOC detects and meets GB GB/T 26395-2011, and heavy metal analysis meets EN71-3.The blue or green ink of the pure water type cork paper gravure that the present invention produces is applicable to intaglio printing, and the production technique of ink is simple, good leveling property, and print speed can reach 100 ~ 200m/min, printability and printing performance good.One of the easiest produced problem of general water color ink is rate of drying very slow (as 50-60m/min), can not reach the requirement of printing press.And the present invention is by raw-material combination and counterweight, solve this problem well.
