Description
Technical field
The invention belongs to printing ink field, relate to antibacterial aqueous ink of a kind of garlicin and preparation method thereof.
Background technology
In recent years, China strengthens packages printing in the requirement aspect safety and sanitation and environmental protection, especially aspect food product pack.In our life, the harmful microorganisms such as various germs, fungi and virus are ubiquitous, not only under certain envrionment conditions, pollute the food in packaging, and people's also easy health risk in the time touching the printed matter that speckles with microorganism.In order to solve the pollution problem of microorganism to packing content things such as food, can take antibacterial ink printing, reduce microbiological contamination.The antibacterial ink inorganic antiseptics that contain the heavy metal such as Ag, Cu that adopt at present, although can resist to a certain extent the pollution of bacterium to packing content thing, heavy metal ion is more serious to the harm meeting of human health more.Existing a lot of ink is all the ink of organic solvent type, in use procedure, can produce VOCs, contaminate environment, and residual organic solvent also can be unfavorable to the mankind's health simultaneously.Although develop now some water color inks, common water color ink has not had anti-microbial property yet, can not extend the shelf-lives of food.In order to meet the growing health demand of people, need at present a kind of water color ink with high-efficiency antimicrobial performance of development badly, can make printing there is efficient anti-microbial property, effectively cut off the route of transmission of germ, ensure the safety of product and the mankind's health.
Summary of the invention
The shortcoming existing for prior art is with not enough, and primary and foremost purpose of the present invention is to provide a kind of garlicin antibacterial aqueous ink.The invention provides the antibacterial aqueous ink of garlicin of a kind of nontoxic, good anti-bacterial effect and environmental protection, solving the pollution problem of conventional organic solvents type ink and water color ink does not have the problem of antibacterial.
A further object of the present invention is to provide the preparation method of the antibacterial aqueous ink of above-mentioned garlicin.
Object of the present invention realizes by following technical scheme: the antibacterial aqueous ink of a kind of garlicin, is prepared by following composition by weight percentage:

Described pigment is any in the pigment dyestuffs such as benzidine yellow G, benzidine yellow G R, light-resistant scarlet BBN, Phthalocyanine Blue BGS or purplish red F2R.
Described garlicin is by natural extract or synthetic.Research shows, garlicin is basic noresidue in animal body, can not cause human body poisoning, carcinogenic and lopsided, also can not produce resistance, is the higher antiseptic-germicide of a kind of security.The chemical structural formula of garlicin is CH2=CH-CH2-S (O)-S-CH2-CH=CH2, and the thioether group in structure and allyl group can be by suppressing bacterial metabolism enzymic activity, damage somatic cells film system and affecting growth, the breeding that thalli growth overall situation suppresses thalline.Garlicin is to various pathogens, as intestinal bacteria, staphylococcus, dysentery coccus, streptococcus pneumoniae, anthrax bacillus, vibrio cholerae, diphtheria corynebacterium etc. have obvious inhibition and killing action, garlicin can also effectively be killed the various moulds such as flavus, aspergillus niger, Aspergillus fumigatus, and garlicin also has restraining effect and killing action to multiple fungi.
Described dispersion agent is any in Silane coupling agent KH550, KH560, KH570, KH792, DL602 and DL171.
Described flow agent is moistening flatting agent LA451.
Described thermo-stabilizer is any in Ca-Zn composite heat stabilizer CH400, CH401 or CH402.
Described defoamer is any in tributyl phosphate, dibutyl phosphate or silicone oil.
Described pure water is deionized water.
The preparation process of the antibacterial aqueous ink of above-mentioned garlicin comprises the steps:
(1) water soluble resin, pigment, dispersion agent, flow agent, Sodium Benzoate, urea and pure water are added in homogenizer successively, and stir pre-dispersed 30～40min under the speed that is 2500r/min at rotating speed, these materials are fully disperseed;
(2) slip step (1) being obtained is squeezed in sand mill circular grinding by toothed gear pump and is distributed to slip fineness and is less than or equal to 20um, prepares mill base;
(3) in the mill base obtaining toward step (2), add garlicin, thermo-stabilizer and halfcystine, then under the speed of 2500r/min, stir 20min with homogenizer, mix;
(4) in the mill base obtaining toward step (3), add Virahol, ethylene glycol ether acetate and defoamer, and stir 20～30min under the speed that is 2000r/min at rotating speed with homogenizer, then add while stirring low Tg value ACRYLIC EMULSION, until stir;
(5) mixture step (4) being obtained filters and packages, and prepares the antibacterial aqueous ink of garlicin.
The present invention has following advantage and effect with respect to prior art:
(1) the present invention adopts the antibacterial composition of garlicin as water color ink, and garlicin is nontoxic, cheap and source is abundant, meets the requirement of environmental protection and food safety.
(2) adopt garlicin as antiseptic-germicide, can utilize thioether group in garlicin molecular structure and allyl group to suppress the activity of bacterial metabolism enzyme, various bacteria and fungi are all had and suppressed and kill activity, there is the function of broad-spectrum antimicrobial.In addition, garlicin, as natural antimicrobial substance, can not produce resistance, has the feature of Durability of antimicrobial effect.
(3) garlicin is a kind of organic antibacterial agent of liquid, can with ink in organic composition well compatible, can fully effectively disperse and maintaining a long-term stability property.
