Problems solved by technology

Counterfeit and inferior products have their own circulation system, especially in the Internet age, when the circulation channels are more complicated. It is impossible to eradicate the circulation of counterfeit and inferior products in the market by controlling the circulation channels. The only feasible way is for consumers to self-verify genuine products and eliminate counterfeit and inferior products
QR codes can be used to communicate with merchants through the Internet, but they cannot be used for anti-counterfeiting, because QR codes can be copied very easily and are not unique, while non-replicable, nearly unique and unpredictable QR codes are An anti-counterfeiting code, which can be used to confirm the product's origin without fail by comparing the camera-capable smart phone and the network with the manufacturer's database

Embodiment 1

[0075] Embodiment 1: the production of pearlescent microspheres——liquid epoxy resin granulation method

[0076] 1. Disperse and mix 10% 325-mesh golden yellow pearlescent toner with liquid bisphenol F epoxy resin with a molecular weight of about 500 at a speed of 8000rpm to obtain a uniform slurry. The dispersion time is 1 hour, and the particle size is less than 30 microns;

[0077] 2. Water-soluble 10% weight diethylenetriamine is mixed with deionized water to obtain mixed solution and add the sodium dodecylbenzenesulfonate surfactant of mixed solution weight 0.2%, the consumption of deionized water is (epoxy resin+ Pearlescent toner) 3 times, the dispersion speed is medium and low speed, with no large amount of foam as the index;

[0078] 3. Add the material obtained in step 2 into the water in which the curing agent is dissolved and stir to cure the epoxy resin into small particles, and the dispersion speed is about 1200rpm;

[0079] 4. Continue to stir and heat to 60...

Embodiment 2

[0087] Embodiment 2: the production of pearlescent microbeads---microbead method

[0088] 1. Wash the glass beads between 32-35 mesh with an equal volume of 1N sulfuric acid, then treat with an equal volume of 1N sodium hydroxide lye, and finally wash with deionized water, and filter the water through a sieve.

[0089] 2. Add 2N ferric sulfate aqueous solution to the treated microbeads in step 1, the weight of the ferric sulfate aqueous solution is twice the weight of the microbeads, and the stirring speed ensures that the microbeads do not sink to the bottom, so that the reaction is uniform.

[0090] 3. Use a metering pump to add 2N sodium hydroxide lye at a constant speed to make the pH of the microbead solution reach 9. The pump speed is 4 hours to add the required lye, and continue to react for 5 hours, and then wash with deionized water to near neutrality.

[0091] 4. The microbeads obtained in step 3 were filtered and dehydrated through a sieve, dried under ventilati...

Embodiment 3

[0092] Embodiment 3 ink production process

[0093] Dissolve 20% by weight of polymethacrylate in a solvent mixed with 80% by weight of dimethylbenzene and methyl isobutyl ketone at a weight ratio of 1:1, stir at high speed to dissolve, and let stand overnight to debubble to obtain a transparent resin solution ;

[0094] Add the required three colors of pearlescent beads, the size of which is 32-35 mesh, the total amount of pearlescent beads is 30% of the total weight of the resin solution, and the volume ratio of various colored pearlescent beads is 1:1:1. Mix evenly at low speed to get ink. If the viscosity is too high, you can use solvent to lower it. The viscosity range is 1000-2000cP.

Abstract

The invention belongs to the technical field of anti-counterfeit and particularly relates to a two-dimensional code anti-counterfeit label and a printing method thereof. The two-dimensional code anti-counterfeit label is obtained by the following method comprising the following steps: (1) preparing pearlescent microbeads of different colors, wherein the particle size of each pearlescent microbead is 0.1-3mm; (2) adding the pearlescent microbeads obtained in the step (1) to printing ink taking resin as a main ingredient, and mixing to obtain special printing ink for printing the two-dimensional anti-counterfeit label, wherein the use amount of the pearlescent microbeads is 5-80 percent of the weight of the resin and more than three colors of pearlescent microbeads are selected; (3) printing a two-dimensional code pattern by adopting the special printing ink on a product or label paper to be subjected to two-dimensional code printing, so that each cell of the two-dimensional code is internally printed with no more than one pearlescent microbead, and the pearlescent microbeads of more than three colors randomly form a special two-dimensional code pattern. The two-dimensional code anti-counterfeit label disclosed by the invention is hardly repeated, the repetition probability is less than 10 parts per billion, and even so, the repetition can be eliminated through a detection system.

Description

technical field [0001] The invention belongs to the field of anti-counterfeiting technology, and in particular relates to a two-dimensional code anti-counterfeiting label and a printing method thereof. Background technique [0002] Counterfeit and inferior products have always been the enemy of legitimate companies. Now there is no simple anti-counterfeiting system that can really distinguish fake and inferior products. Even multi-layer laser anti-counterfeiting labels can be imitated with the same technology. Counterfeit and inferior products have their own circulation system, especially in the Internet age, when distribution channels are more complicated. It is impossible to eradicate the circulation of counterfeit and inferior products in the market by controlling the circulation channels. The only feasible way is for consumers to self-verify genuine products and eliminate counterfeit and inferior products. QR codes can be used to communicate with merchants through the In...
