Abstract
The invention relates to ink, in particular to water-based visible ultraviolet excited ink and a preparation method thereof. The ink is prepared from raw materials in percentage by mass as follows: 32%-37% of a pigment, 41%-45% of an emulsion vehicle, 8%-10% of an alcohol solvent, 0.4%-0.6% of a pH regulator, 3.0%-3.2% of a leveling agent, 0.1%-0.2% of a photosensitizer, 0.2%-0.4% of an antifoaming agent and 9%-13% of deionized water. The anti-forgery ink is water-based ink meeting environmental requirements for emission of VOC (volatile organic compounds), meets FDA (Food and Drug Administration) hygiene requirements, and is environment-friendly and pollution-free; the ink has good printability and fluorescent effect due to addition of the photosensitizer, can be well applied to the anti-counterfeiting printing industry, and is good in fluorescent falsification prevention effect and low in cost; and meanwhile, the ink can be further applied to adhesive sticker type labels and various printing stocks for films for printing. The preparation method of the ink is scientific, reasonable and easy to implement.
Description
Technical field
The present invention relates to ink, be specifically related to the visible burst of ultraviolel ink of a kind of water-based and compound method thereof.
Background technology
For false proof enterprise, the use of anti-forgery ink is the most extensive.Anti-forgery ink is of a great variety, fluorescent ink because of its significant antifalse effect generally approve by industry.But for the meagre profit type mode of production of false proof enterprise, the most extraordinary anti-forgery ink in market is difficult to be promoted because of the price of its costliness, and under ordinary light, the rate of utilization of visible burst of ultraviolel anti-forgery ink is especially low.At present, flexographic printing anti-forgery ink all adopts the visible ink of first printing, and ink then will be excited to carry out double exposure, and obtain the combination of visible mass colour and burst of ultraviolel mass colour, process is numerous and diverse, and cost is high.
In addition, the use of burst of ultraviolel ink also has many restricted conditions in cost and printing process, based on above consideration, needs exploitation one badly and greatly reduces printing cost, reduce process complexity, the water-based burst of ultraviolel ink that antifalse effect is good.
Summary of the invention
The object of this invention is to provide that a kind of fluorescence falsification preventing is effective, cost is low, environment-friendly water-based visible burst of ultraviolel ink; The present invention provides its preparation method simultaneously.
The visible burst of ultraviolel ink of water-based of the present invention, be made up of the raw material of following mass percent:
Wherein, preferred technical scheme is as follows:
Described pigment is the mixture of chrome yellow and fluorescein mass ratio 1:1.1 ~ 1.3, the preferred Alexa Fluor 633 of fluorescein.
Described emulsion binder is aqueous acrylic emulsion resin R-20B.
Described alcoholic solvent is the ethanol of 95wt.%.
Described pH adjusting agent is 2-amino-2-methyl-1-propanol, preferred AMP-95.
Described flow agent is 3-butoxy-1-propyl alcohol.
Described defoamer is DF-908.
Described photosensitizer is trans stilbene.
The preparation method of the visible burst of ultraviolel ink of described water-based, comprises the following steps:
(1) alcoholic solvent, emulsion binder, deionized water are added in reactor, stir, insulation;
(2) again pigment, defoamer are added in reactor, be stirred to evenly, obtain work in-process mill base;
(3) adopt beveller that work in-process mill base is ground to mill base fineness and be less than 15 μm;
(4), after adding pH adjusting agent, flow agent and photosensitizer successively in the mill base after grinding, stir, filter and obtain the visible burst of ultraviolel ink of water-based.
Wherein, step (1) heat-retaining condition is incubated 7-8h at 45-50 DEG C.In step (3), fineness is less than 15 μm namely thinner than 15 μm.
Ink of the present invention produces and excites metachromatism under 254nm ultra violet lamp condition.
The present invention is the visible burst of ultraviolel ink of a kind of water-based, is made up of hybrid pigment, emulsion binder, alcoholic solvent, deionized water, pH adjusting agent, flow agent and defoamer.Generally the ink fluorescent effect of preparation is poor like this, and in order to obtain good fluorescent effect, the present invention introduces photosensitizer breakthroughly, makes ink have good printability and fluorescent effect.
Beneficial effect of the present invention is as follows:
Anti-forgery ink of the present invention is the water color ink that a kind of VOC discharge meets environmental requirement, meets the hygienic requirements of U.S. FDA, environment friendly and pollution-free; The present invention is by adding photosensitizer, and make ink have good printability and fluorescent effect, can be advantageously applied to anti-counterfeit printing industry, fluorescence falsification preventing is effective, cost is low; Also can be used in the stock of non-setting adhesive class label and various film for printing simultaneously.The preparation method of ink of the present invention is scientific and reasonable, be easy to realize.
