Description
Technical field
The present invention relates to field of anti-counterfeit technology more particularly to a kind of fluorescent ink and preparation method thereof.
Background technique
Fluorescent ink is in ticket printing using one of more ink, and main component is fluorescent pigment and fluorescence dye
Material.Fluorescent pigment function of dominant luminous pigment, the difference with general pigment are to inhale when ambient light (containing ultraviolet light) irradiation
Receive the energy of certain form, and excitation photon, the energy of absorption is released in the form of low visible light, to generate different form and aspect
Fluorescence phenomenon.Different color light, which combines, forms abnormal gay colours, and after light stops irradiating, luminescence phenomenon disappears, because
Referred to herein as fluorescent pigment.Fluorescent pigment and macromolecule resin binder, solvent and auxiliary agent match, ground that fluoroleum is made
Ink.This all invisible ink of naked eyes shines only under ultraviolet light or infrared light, just because of the convertible and hidden of it
The feature of hiding and make the ink in specialty printing industry the characteristics of cannot accurately be replicated on color copy machine
Using relatively more universal.
Fluorescent ink is one of most important branch of anti-forgery ink, while being also the ivy of anti-forgery ink technical field.
Fluorescent ink on existing market can be divided into burst of ultraviolel, infrared excitation and excited by visible light three categories according to exciting light, mainly
Technical characteristic is when exciting light is irradiated on the picture and text marking by fluorescent ink printing, and the marking issues the spoke based on visible light
It penetrates, this technology is quite mature, and anti-fake rank is relatively low.It is badly in need of the relatively high fluorescent ink of anti-counterfeiting power in the market newly to produce
Product.
Summary of the invention
It is unique that it is an object of the present invention to provide a kind of antifalse effects, the high fluorescent ink of anti-fake rank.
It is another object of the present invention to provide the preparation methods of above-mentioned anti-forgery ink.
It is another object of the present invention to provide the discrimination methods of above-mentioned anti-forgery ink.
In order to solve the above technical problems, the technical solution adopted by the present invention is that:
A kind of fluorescent ink is mixed to prepare by component A and component B, wherein the component A includes rare-earth europium salt and 1- benzene
Base -1,3- diacetyl reacts in a solvent to be made, and component B includes polyamide, ethyl alcohol, isopropanol, n-butanol and auxiliary agent.
Preferably, the rare-earth europium salt is nitrate or villaumite, and the solvent is the mixing of ethyl alcohol, isopropanol and n-butanol
Solvent, the auxiliary agent include erucyl amide and wax powder.
Preferably, fluorescent ink of the invention includes: in parts by weight
It is furthermore preferred that in parts by weight including following component:
Further, the fluorescent ink marking is transparent, does not have fluorescent emission under ultraviolet light irradiation, is using specific object
After matter processing, under ultraviolet light irradiation, the marking issues fluorescence response.
Preferably, the predetermined substance is one of ethamine, diethylamine and Triethylamine gas substance or mixture.
The present invention also provides the preparation methods of above-mentioned fluorescent ink, specifically includes the following steps:
(1) rare-earth europium salt and 1- phenyl -1,3- diacetyl are reacted in a solvent, a kind of solution is made；
(2) by solution obtained in step (1) with polyamide, ethyl alcohol, isopropanol, n-butanol and auxiliary agent with certain
Mass ratio concussion dispersion, filters to obtain a kind of fluorescent ink.
Preferably, the mixed solvent of the ethyl alcohol of solvent described in step (1), isopropanol and n-butanol, described in step (2)
Auxiliary agent is erucyl amide and wax powder.
The present invention also provides the anti false authentication methods of above-mentioned fluorescent ink, comprising the following steps:
S1: it is irradiated under ultraviolet lamp, the marking does not have fluorescent emission；
S2: being added predetermined substance, and the predetermined substance is alkaline matter；
S3: irradiating under ultraviolet lamp, and the marking issues bright red；
S4: the specific gas substance in second step is removed with common hair dryer；
S5: it is irradiated under ultraviolet lamp, the marking does not have fluorescent emission.
Preferably, the predetermined substance is one of ethamine, diethylamine and Triethylamine gas substance or mixture.
The fluorescent ink marking provided by the invention is transparent, does not have fluorescent emission under ultraviolet light irradiation, has quite high
Concealment；After being handled using predetermined substance, under ultraviolet light irradiation, the marking issues fluorescence response, issues bright feux rouges；When
After removing predetermined substance (key), no fluorescent emission is returned to again in the UV lamp, such antifalse effect is very unique, anti-
Pseudo- rank is higher than conventional printing ink；Preparation process is simply at low cost, and popularization resistance is small, has broad application prospects.
Detailed description of the invention
Fig. 1 is the antifalse effect figure of fluorescent ink of the present invention.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, but do not constitute limiting the scope of the invention.
The proportion of fluorescent ink of the invention is as shown in the table:
Firstly, mainly including rare-earth europium salt (nitrate or villaumite) and 1- phenyl -1,3- fourth in fluorescent ink of the invention
Diketone, the two is mixed in any proportion can have unique antifalse effect, and the present embodiment is only with preferably embodiment
