Description
Technical field
The present invention relates to field of anti-counterfeit technology, and in particular to a kind of preparation process of Magnetic guidance development anti-counterfeiting mark and is made
Anti-counterfeiting mark.
Background technique
Anti-counterfeiting technology is to identify a kind of technology of authenticity of products, but the means that criminal fakes also are continuously improved, perhaps
More counterfeit protection measures have gradually lost its uniqueness, anti-fake therefore, it is difficult to achieve the purpose that, the release of new anti-counterfeiting technology, which becomes, to disappear
Take the urgent need in market.
There is universal concern for magnetic anti-counterfeit material both at home and abroad, Magnetic guidance developing material is a kind of novel nanometer
Material, belongs to the scope of photonic crystal, and such material has already passed through scientific research exploration, realizes such material package in laboratory
With in material, the Magnetic guidance developing material of paramagnetic is solidified on the rougher substrate in surface by photocuring.In recent years
There are many scientific research institutions successfully to have developed nano magnetic Induced Photon crystalline material, but because of the office of applications to nanostructures popularization
Sex-limited, such material is difficult to realize industrialize.
Up to now, there are no such applications in anti-counterfeiting mark.The application of Magnetic guidance developing material is primarily limited to
Two aspects, are on the one hand the selections for identifying substrate, still further aspect be Magnetic guidance developing material adhesive force on base material with
And stability.Adhesive force is small to cause such material to be difficult to film-forming on the substrate, and stability is bad to lead to Magnetic guidance effect
Unstable, the two predicaments are that such material is applied to anti-fake industry head technical problems to be solved.
Summary of the invention
That the object of the present invention is to provide a kind of adhesive force is strong, stability is good, the Magnetic guidance development with Magnetic guidance effect is anti-
Puppet mark, present invention simultaneously provides its preparation processes.
The preparation process of Magnetic guidance development anti-counterfeiting mark of the present invention, comprising the following steps:
(1) paramagnetism ferroferric oxide powder is mixed with polyurethane light-cured resin, ethylene glycol is added, using ultraviolet light
Initiation reaction is irradiated, Magnetic guidance development nano material coating fluid is made；
(2) gravure coating method is utilized, Magnetic guidance development nano material coating fluid is coated in substrate using anilox roll,
Magnetic guidance development coating is obtained after dry solidification；
(3) on the Magnetic guidance development coating that step (2) obtains, gloss oil is coated, it is aobvious to Magnetic guidance by ultraviolet light solidification
Shadow coating is packaged covering；
(4) it by the Magnetic guidance development coating after encapsulation covering, is first coated using adhesive, then be dried, finally
Surface coating is carried out, Magnetic guidance development anti-counterfeiting mark is made.
Wherein, preferred technical solution is as follows:
In step (1), the mass ratio of paramagnetism ferroferric oxide powder and polyurethane light-cured resin is 1:20~25, second
Glycol volume and polyurethane light-cured resin mass ratio are 3~4:1, and ethylene glycol is in terms of L, and polyurethane light-cured resin is with Kg
Meter.The preferred UV3000-B of polyurethane light-cured resin reacts 45~50min under 254nm ultraviolet light.
In step (2), drying temperature is 85~90 DEG C, and speed is 41~45m/min, and anilox roll is 200 or 220 mesh, base
Bottom is paper or PET film.
Adhesive force is high after Magnetic guidance of the present invention development nano material coating fluid film forming, with taking off after No. 6 tape-strippings of 3M standard
It plays coating cloth to fall off, and hardness is suitable for, and successfully solves the problems, such as that Magnetic guidance developing material adhesive force in substrate is low.
In step (3), gloss oil is sub- beauty UV-1100 or UV-1200, and gloss oil is coated by way of silk-screen, silk screen
For 200 or 250 mesh, speed is 30~35m/min.
In step (4) adhesive be CF-206 solvent type adhesive, speed be 45~50m/min, drying temperature be 100~
110 DEG C, overlay film uses the BOPET film of 12~20 μ m thicks.Overlay film plays a protective role to anti-counterfeiting mark, both prevents in air
Impurity etc. it is polluted, prevent surface abrasion, keep Magnetic guidance material more stable, also make it more beautiful.
The present invention can also be compound by the substrate of Magnetic guidance development anti-counterfeiting mark and release paper, then is die cut, and is made single
A anti-counterfeiting mark.It is preferred that using hot-fusible pressure-sensitive adhesive that the substrate of Magnetic guidance development anti-counterfeiting mark and release paper is compound.Coating heat
The speed of molten pressure sensitive adhesive is 50~55m/min, and hot-fusible pressure-sensitive adhesive glue amount is controlled in 16~18g/m2。
Beneficial effects of the present invention are as follows:
The present invention solves the application problem of Magnetic guidance development nano material product, breaches Magnetic guidance development nano material
The magnetic induction nano material of paramagnetic is used in anti-fake material or anti-counterfeiting mark, is easy to discern the false from the genuine by industrialized bottleneck, realizes
Unique antifalse effect.Anti-counterfeiting mark Magnetic guidance development coating adhesion of the present invention is strong, stability is good.
Under normal condition, anti-counterfeiting mark of the present invention contains stealthy information, no visual information.By being placed around in mark
The methods of magnet generates externally-applied magnetic field, and the information for inducing it stealthy is as it can be seen that simple, intuitive, can not copy, anti-counterfeiting power is strong.
