Description
Technical field
The present invention relates to anti-counterfeiting technology, particularly relate to a kind of anti-fake material and preparation method thereof.
Background technology
In existing skill counterfeit-proof tech, mostly with watermark, colored fibre, fluorescent ink printing, microdot or the body of small mark
And random distribution etc. is as counterfeit protection measures.
Such as, prior art 1, Chinese patent literature CN102108653A, disclosed a kind of lamellar anti-fake material, described
Shape anti-fake material uses the polymorphic structure beyond square；And described lamellar anti-fake material is made up of following layer structure: paper
The false proof carrier layer of matter, the false proof carrier of wherein said papery is to be compounded by least two fiber to manufacture the paper obtained；And it is false proof
Layer.Also disclose the preparation method of described lamellar anti-fake material and the cheque paper containing this lamellar anti-fake material.The present invention's
Lamellar anti-fake material can obtain and be provided simultaneously with multi-level anti-fraud functional anti-such as naked eyes identification, the most machine-readable, analysis expert
Pseudo-paper.
For another example, prior art 2, Chinese patent literature CN104610812A, disclosed fluorescence silicon nano particles are as anti-
The application of pseudo-labelling, is prepared fluorescence silicon nano particles by silicon source, the fluorescence silicon nano particles obtained is used as anti-counterfeiting ink system
Standby security pattern.Owing to nano silicon particles has good photoluminescent property, quantum yield is high, and storage stability is good, has good
Excitation wavelength dependency, the security pattern of preparation can show the light of different colours under the illumination of different excitation wavelengths, can rise
To good antifalse effect.
For another example, prior art 3, Chinese patent literature CN101673341A, disclosed in the present invention relates to anti-counterfeiting technology, especially
It relates to a kind of anti-counterfeiting method of micro-points.The method comprises the following steps: (1) provides a kind of microdot；(2) a kind of glue is provided, will
Microdot is mixed among glue；(3) the mixed atomarius glue of point on carrier；(4) solidified glue；(5) glue of taking pictures drips, and is formed
Original Contrast's picture；(6) original Contrast's picture is stored in background data base；(7) fake certification glue of taking pictures drips, and is formed by than picture；
(8) read background data base original Contrast's picture, and compared than picture, make the true and false and judge；Wherein, described in (5th) step
Glue of taking pictures drips, and takes pictures for amplifying；Fake certification described in (7th) step glue of taking pictures drips, and is also to amplify to take pictures.The present invention provides a kind of
The most imitability anti-counterfeiting method of micro-points.Corresponding, Chinese patent literature CN102267287A discloses a kind of similar one
The preparation method of kind of microdot anti-counterfeiting stamp and and realize the device of the method.The preparation method of microdot anti-counterfeiting stamp includes following step
Rapid: S1, it is provided that a kind of microdot label, it is provided that a kind of ink；S2, mixed ink, will mix homogeneously with ink by microdot label；
S3, it is provided that at least two shower nozzles, it is provided that object；S4, injection, by shower nozzle, the ink being mixed with microdot label is sprayed to target
Thing；S5, is dried the ink being mixed with microdot label；In course of injection, mixed ink step is carried out continuously, mixed black, to shower nozzle confession
Ink, injection complete in totally enclosed fluid path.The present invention provides in a kind of course of processing and is difficult to be mixed into impurity, keep in real time
The preparation method of the microdot anti-counterfeiting stamp that microdot is evenly distributed in ink and realize the device of the method.
For another example, prior art 4, Chinese patent literature CN1350274A, disclosed one contain most small mark or
Anti-fake mark of pattern and forming method thereof, with the anti-fake mark containing most micro pattern marks, reaches qualification article genuine-fake
And prevent the application forged.Object qualification method is that it contains many according at least one unique tag formed in object
Number micro patterns or mark, and together in labelling in the way of random combine, with as a comparison, the method identified, and have anti-
Only other people forge and can be easily achievable and identify and identify and effect of contrast.
For another example, prior art 5, Chinese patent literature CN105489112A, the present invention relates to anti-counterfeiting technology, particularly relate to
A kind of anti-fake material and preparation method thereof, anti-fake material includes the monocrystal silicon module of lamellar, and monocrystal silicon module has void region,
Anti-fake material also includes metal module, and metal module is embedded in described void region；The preparation method of anti-fake material, by glass
Plate adhesive layer, plating sacrifice layer, plating monocrystalline silicon layer above glass substrate, coating light binding, expose, develop, clean, etching monocrystal silicon
Layer, second glue spreading, exposes, develops, cleans, plating module, cleans light binding, etching sacrificial layer, cleans filtration；The present invention carries
For one, there is many materials, relief anti-fake material and preparation method thereof.
But, the most listed above 1 to 4, the composite fibre of prior art, fluorescence silicon nano particles, microdot or small note
Number body and random distribution etc. as counterfeit protection measures, be not to be possible to prevent other people to forge as disclosure describes
Effect, along with the progress of science and technology, these technological means all can inexpensively be copied, it is impossible to imitated only prior art 3 institute
The background data base stated, but back-end data is the most dangerous, and the data base of enterprise is easily subject to assault, and needs communication to pacify
All risk insurance hinders, the most undesirable.Above-mentioned prior art 5, although overcome the defect of prior art, but metal becomes with single crystal silicon material
This is the highest, and process costs is the highest, especially etches monocrystalline silicon layer, needs expensive ICP equipment, for domestic consumer, implements
Pressure is bigger.Thus, the anti-fake material of prior art and counterfeit protection measures all have potential safety hazard more or less, without potential safety hazard
Cost is high, needs constantly to weed out the old and bring forth the new, constantly improves.
Summary of the invention
