Description
Technical field
The present invention relates to a kind of preparation method of diaphragm, particularly it is a kind of can as the diaphragm of three-dimension code preparation side
Method, belongs to false proof discriminating field.
Background technology
One-dimensional bar code is the multiple secret notes and blank for not waiting width, and one group is expressed according to certain regularly arranged rear use
The graphical identifier of information.The pattern of parallel lines that the secret note and informal voucher that it is differed greatly by reflectivity are lined up is constituted.By nearly 100
The development in year, one-dimensional bar code has developed more maturation, with lot of advantages：It is easy to making, standardization level is high, easily know
Reading, high input speed, reliability be high, easily with to read equipment online, but with needing to store the increase of information content, one-dimensional barcode
Code gradually shows small, the easily imitated deficiency of capacity.
Quick Response Code is to be distributed chequered with black and white lines in the plane, to record data by certain specific geometric figure
Symbolic information.For one-dimensional bar code, Quick Response Code has density of encoding height, information capacity is big, coding range is wide, cost
It is low it is easy make, available for it is anti-fake encrpted the advantages of.But common Quick Response Code is to be present in image format on two dimensional surface, can
Easily to reappear Quick Response Code by way of scanning, printing, therefore common Quick Response Code does not have antiforge function.In recent years
Come, to strengthen the antiforge function of Quick Response Code, patent 201410199094.X discloses a kind of anti-fake two-dimension code, this Quick Response Code bag
Include profiling two-dimentional code layer and hidden pattern layer.Stealthy patterned layer is printed using special printing-ink, passes through ultraviolet identifier
Just it is observed that with infrared identification instrument.By the overlapping printing of dominant two-dimentional code layer and hidden pattern layer, protection two dimension is reached
The purpose of code layer.But this Quick Response Code needs to repeat print, technique slightly complicated.
Three-dimension code is a kind of emerging bar code, is to be further added by a kind of information dimension on the basis of Quick Response Code to improve letter
The amount of storage of breath.The information carrier of third dimension is commonly used as using color.By different color combination table registrations it is believed that
Breath, although the structure with Quick Response Code, but information density is much larger than two-dimensional bar code.The mode of another increase third dimension
It is that fluorescent material is added in ink.Such as patent 201610067272.2 discloses a kind of fluorescence battle array for printing fluorescent ink
Row overlap the preparation method to form three-dimension code with Quick Response Code, and the information of this three-dimension code needs to print twice, and need to carry
The identification equipment of generating laser could be used, and be difficult to be used by domestic consumer.
The content of the invention
It is an object of the invention to overcome the shortcomings of above-mentioned three-dimension code, there is provided a kind of three-dimension code diaphragm on preparing and using
Preparation method, the invented technology is simple, without expensive device.
To achieve the above objectives, the present invention, which is adopted the following technical scheme that, is achieved, a kind of system of three-dimension code diaphragm
Preparation Method, it is characterised in that comprise the steps：
(1) preparation of casting solution：High molecular polymer and graphite are added in organic solvent, is stirred vigorously and is allowed to complete
Dispersing and dissolving obtains casting solution, and the mass ratio of high molecular polymer and organic solvent is (0.05~0.4): 1, high molecular polymer
Mass ratio with graphite is (1~30): 1；
(2) flow casting molding：Casting solution is cast into diaphragm in casting machine, then diaphragm soaked to 0 in coagulating bath~
24 hours, taken out from coagulating bath, be subsequently dried the diaphragm for obtaining that thickness is 0.1~1mm；
(3) plastic packaging：Dried diaphragm is placed in plastic packaging in plastic packaging machine, that is, obtains three-dimension code diaphragm.
High molecular polymer in the step (1) is one in Kynoar, polyvinyl chloride, polyvinylpyrrolidone
The mixture of kind or a variety of arbitrary proportions；Graphite is flaky graphite, and particle diameter is 0.1~0.5mm；Organic solvent is dimethyl methyl
The mixture of one or more arbitrary proportions in acid amides, dimethyl acetamide, METHYLPYRROLIDONE；High molecular polymerization
The whipping temp that thing and graphite are added in organic solvent is 20~90 DEG C, and mixing time is 1~24 hour；High molecular polymer
Addition sequence with graphite is first to add after graphite to add high molecular polymer or add stone after first adding high molecular polymer
Ink or high molecular polymer and graphite are added simultaneously；Agitating mode is stirred or stirred while adding afterwards first to add.
2. described in coagulating bath in step (2) be water, or water and organic solvent used mixture；Organic solvent is solidifying
Gu the weight/mass percentage composition in bath is 0~60%, the temperature of coagulating bath is 20~80 DEG C；Drying temperature is 20~105 DEG C, is dried
Time is 0.5~12 hour.
Plastic packaging temperature in the step (3) is 90~180 DEG C.
The present invention principle be：Graphite is evenly distributed in casting solution, using the solvent in casting solution and coagulating bath it
Between the process that is exchanged solidify diaphragm, and graphite is solidificated in diaphragm simultaneously.Because distribution of the graphite in casting solution is
Random, so the graphite in diaphragm is also random distribution.As a kind of diaphragm available for three-dimension code, its two-dimensional signal is
What the position being distributed using graphite in diaphragm was determined.The information of the third dimension is represented using the gray scale of graphite, because stone
The depth that is distributed on diaphragm thickness direction of ink is different, and the gray scale showed is also different, and the depth of Graphite Distribution be also with
Machine, therefore the gray scale that graphite is showed is also random.
It is characteristic of the invention that：Graphite is randomly dispersed in diaphragm, diaphragm is provided with uniqueness.Per piece of graphite
Relative position in diaphragm contains the information of X, Y two dimension.Graphite is black, and diaphragm is white, and graphite is caught in diaphragm
The depth for doing distribution is different, and the gray scale that graphite is showed is also different, the blackness showed close to the graphite of membrane surface
Greatly, the blackness that the graphite away from membrane surface is showed is small, therefore the depth that graphite is distributed in diaphragm is different, is that diaphragm increases
The information of Z-direction is added, so that the information for being truly realized diaphragm in tri- dimensions of X, Y, Z is stored.Simultaneously by diaphragm plastic packaging
Get up, play protection diaphragm and the purpose for preventing diaphragm to be utilized again.
Beneficial effect：Existing Quick Response Code is distributed in the two-dimensional direction according to certain rules with specific geometric figure
Chequered with black and white graphic recording data.Compared with Quick Response Code, three-dimension code diaphragm of the present invention is using greyish white alternate
Graphic recording data, difference is essentially consisted in：1) particle diameter of graphite is less than the thickness of diaphragm, and Graphite Distribution is in diaphragm, therefore
What graphite was displayed is gray scale, and depth of the gray scale because of graphite in diaphragm is different and different；2) particle diameter of graphite particle
Change within the specific limits, the particle diameter of each particle is random, and point of the graphite particle in diaphragm in the range of this
Cloth is also random random, that is, the pattern formed does not have rule, therefore diaphragm has uniqueness；3) intensity of diaphragm itself
It is not high, and pass through plastic packaging.If broken ring plastic packaging necessarily destroys diaphragm, therefore diaphragm of the present invention is not with reproducible
Property.Because the present invention has above feature, therefore available for the commodity counterfeit prevention field of three-dimension code.
