Description
Technical field：
The present invention relates to offset ink technical fields, and in particular, to a kind of green ink for packing bag for medical use and
Preparation method.
Background technology：
Offset ink is mainly the coloured material of flow-like being made of pigment, auxiliary agent, high molecular polymer and solvent,
In, the primary solvent of offset ink is mineral oil and vegetable oil.The drying process that offset ink is printed onto on paper is very multiple
Miscellaneous, we, which can be understood as ink, is dried by the oxidation filming of mineral oil infiltration and vegetable oil.Ink conduct
A kind of most important printing material of information regeneration should have good printability in printing process.Offset ink is main
It is by material compositions such as colored pigment, binder, filler material and auxiliary agents, when preparing by the requirement of printing according to certain ratio
It is mixed, and is rolled made of black technique by rolling.Colored pigment be insoluble in water be also insoluble in oil or binder, have
The solid, powdery substance of certain color.It is not only main solid constituent in ink and prints to visible on object
Coloured body portion largely determines the color of ink, dilute performances such as thick, fast light.Binder is the heart of ink, belongs to glue
Glutinous shape fluid；In ink, it can link up the material mixings such as the pigment of powdery, be allowed to after grinding distribution, form tool
There are certain fluidity and the adherent of viscosity, so as to play the role of connection.Binder is main fluid constituent in ink,
Determine fluidity, viscosity, dryness and printability of ink etc..Filler material is white, transparent, translucent or opaque powder
The solid component part of shape substance and ink, mainly plays filling effect.It is appropriate to select filler material, in addition to pigment can be reduced
Dosage is reduced outside cost, it can also adjust the property of ink, such as dilute thick, fluidity.Auxiliary agent is adding into ink
Point, the additional material of ink finished product is can also be used as, the certain properties for changing as printing adjuvant or improving ink, such as：It is dry
Dry property, rub resistance etc..
As the improvement of people's living standards, higher requirement is proposed to environmental quality, health and the health of itself, it is right
In the bacterium that can not see of naked eyes, people are even more that can not put up with that its is potentially hazardous, more especially high for sanitary index
Packing bag for medical use and dustless food workshop etc., this is not only concerning the production environment to the producer in itself, also concerning to its product
The masses of sale, current market sales of offset ink do not have anti-microbial property, print out to come using these offset inks
Product also do not have anti-microbial property, surface becomes easily infected by bacterium, it is difficult to meet the needs of people, application No. is
CN201410362497.1 discloses a kind of printing ink of traditional Chinese medicine ingredients containing antibiotic property, and zinc oxide, smalt are added in component
Leaf, the coptis carry out antibacterial, anti-microbial property is single, and effect is not for antibacterial using big yellow leaf, the automatic sterilization function characteristic of the coptis
Significantly, application No. is CN1195120C to be related to antibacterial ink, using inorganic carrying silver antimicrobials.Single carrying metal ion is inorganic anti-
Or antibacterial effect is not notable when microbial inoculum adds use in ink or product is made to change colour, the zeolite of carrying silver ion is such as used
Or the sample antibacterial effect reproducibility that the addition of silica type antiseptic obtains in ink is bad or not notable, and in ink system
It is more serious to the abrasion of the equipment such as three-roller during work, be not suitable for printing ink to manufacture.
Invention content：
The present invention overcomes the defects of prior art, provides a kind of green ink for packing bag for medical use and its preparation side
Method has the advantages that environmentally protective, durable antibiotic sterilization.
The technical problems to be solved by the invention are realized using following technical scheme：A kind of green for packing bag for medical use
Ink, by weight, including 60~70 parts of binder；4~6 parts of pigment, 30~40 parts of filler, 30~40 parts of solvent, sterilization
1~3 part of agent；The filler is nano-titanium dioxide；The fungicide includes natural bactericidal agent and composite inorganic antimicrobial agent,
Applicant has found by creative work, when the weight part ratio of natural bactericidal agent and composite inorganic antimicrobial agent is 2：When 1, prepare
The ink anti-microbial property of formation and the performance of ink are best.
In the present invention, the binder is prepared by following steps：
S1：Hard resin, refined soybean oil, soya fatty acid ester are added in four mouthfuls of reaction flasks, are heated to 160 DEG C
It is melted completely to resin, under conditions of nitrogen protection, 75rpm rotating speeds, is continuously heating to 180 DEG C, keeps the temperature 1 hour, set
Lipoprotein solution A；
S2：Above-mentioned solution A is cooled to 145 DEG C, adds in alumina gel agent, is warming up to 170 DEG C, keeps the temperature 0.5 hour, is surveyed viscous
Degree if viscosity is less than 75000mPas/25 DEG C, continues heat preservation and surveyed a viscosity every 15 minutes, until viscosity reaches 85000
~90000mPas/25 DEG C；If viscosity is more than standard value, viscosity is adjusted to qualification with reserved soya fatty acid ester.
The selection pigment of pigment is the present-color material of ink, is directly related to the quality of colour of ink and the stabilization of color
Property, water-based ink pigment is selected it has to be considered that the form and aspect of pigment, are secondly also considered that the gloss of pigment, chemistry are resistance to
The problems such as property, easily disperse and intermiscibility with other components.Pigment in ink is divided into organic pigment and inorganic pigment two
Kind, it is contemplated that most of inorganic pigment contains a certain amount of heavy metal element, generally all has certain toxicity.Therefore it uses
Pigment is organic pigment.The color designed in the present invention be yellow uitramarine, so pigment selection from organic yellow uitramarine
Selection.The type of organic yellow uitramarine has very much, and the pigment that different production men produces, property also have difference.
So when selecting pigment, the color characteristics and Wuli-Shili-Renli system approach of the pigment of different field men are investigated, select Shanghai refined
The yellow uitramarine that the benzidine yellow of connection is used as, with the advantages of of good quality, stability is high.
In the present invention, the solvent includes main solvent and cosolvent, and the main solvent is deionized water, and described helps
Solvent is ethyl alcohol, and the weight ratio of the deionized water and ethyl alcohol is 2：3；It is a kind of alkali in view of binder selected in the present invention
Property resin, if the hardness of water is excessive, in water-based ink this alkaline system, easily so that ink generates precipitation, for oil
Ink storage it is unfavorable, therefore select deionized water, in the preparation process of water-based ink binder, in addition to use main solvent water with
Outside, it in order to prepare the better binder of performance, needs to add some cosolvents, selected cosolvent must dissolve used
Resin, ammonium and salt, can also with water arbitrarily than mixing.Consider two aspects：Solvability of the solvent to high molecular polymer, solvent
From the developability in ink, the drying property of ink, particularly intaglio process can be adjusted using organic solvent in water-based ink
The drying mode of ink is mainly by volatilization in brush, and appropriate organic solvent can adjust the rate of drying of ink, in of the invention
The ethyl alcohol of addition, characteristic are that evaporation rate is 1.9, solubility 26.1, it are made to have good solvability to resin, together
When also feel there is faster rate of drying.
In the present invention, the natural bactericidal agent include juniper, argy wormwood, aloe, Radix Glycyrrhizae, heartleaf houttuynia, tealeaves, granatum, radix scutellariae,
One or more combinations in the coptis, Cortex Phellodendri, bush, madder, chrysanthemum, Asian puccoon, mustard extract, capsicum, garlic, wherein,
