Embodiment 1

[0026] Example 1 The manufacturing method of the integrated anti-counterfeiting mark of ternary integrated nuclear micropore

[0027] The method for manufacturing the integrated anti-counterfeiting mark of ternary integrated nuclear micropores in this embodiment can basically be divided into five relatively independent steps:

[0028] 1. Heavy ion irradiation Use S-32 heavy ions with a total energy of 120 Mev produced by a heavy ion accelerator to irradiate a 28 μm thick transparent polyethylene terephthalate (PET) film in an irradiation vacuum chamber. The heavy ion beam intensity is 100nA, the electromagnetic scanning width is 40cm, and the film running speed is 25m / min. The heavy ion irradiation process is a disordered random process, so nuclear latent traces obeying the statistical law are formed in the irradiated PET film.

[0029] 2. Laser rainbow molded holographic image production This step is completely independent from the above step 1, which is convenient for contr...

Embodiment 2

[0037] Manufacturing method of integrated anti-counterfeiting label of binary integrated nuclear micropore

[0038] The dual integrated nuclear microporous comprehensive anti-counterfeiting mark is derived from the ternary integrated anti-counterfeiting product with the same technical performance but different from each other. The method for manufacturing the integrated anti-counterfeiting mark of binary integrated nuclear micropores of the present invention can basically be divided into 5 relatively independent steps:

[0039] 1, heavy ion irradiation; this step is identical with the step 1 of embodiment 1

[0040] 2. Fabrication of laser rainbow embossed holographic images; this step is the same as step 2 of embodiment 1.

[0041] 3. Printing anti-counterfeiting marks; this step is basically the same as Step 3 of Embodiment 1. The difference is that the nuclear microhole pattern and characters are distributed in a certain sequence to ensure that each laser holographic anti...

Embodiment 3

[0045] Example 3 Manufacturing method of composite nuclear microporous anti-counterfeiting label

[0046] The composite nuclear micropore anti-counterfeiting mark is derived from the binary integrated nuclear micropore anti-counterfeiting mark, and is an anti-counterfeiting product with the same technical performance but not the same. Basically, it can be divided into 5 relatively independent steps:

[0047] 1. Heavy ion irradiation This step is the same as step 1 of the embodiment.

[0048] 2. Anti-counterfeiting mark of microporous printing on the concave sheet This step is the same as Step 3 of Example 2.

[0049] 3. Chemical etching of nuclear micropores This step is the same as Step 4 of Example 1.

[0050] 4. Production of laser iridescent holographic anti-counterfeiting marks Applying laser iridescent holographic plate-making technology and molding replication technology to make laser iridescent embossed holographic image anti-counterfeiting marks on ordinary PET alum...

Abstract

The present invention belongs to the field of anti-counterfeit technology, and includes the foloowing steps: irradiating transparent high-molecular polymer film by using heavy ion with a certain energy and mass; making laser rainbow die-stamped holographic image on the irradiated film; printing nuclear microporous marking pattern and characters on the irradiated film; applying or composing a layer of protective layer on the laser rainbow holographic image; and using chemical eatching method to make pore-forming eatching treatment on the above-mentioned film; then cleaning and drying to obtain high-grade anti-counterfeit effect so as to integrate anti-counterfeit property, beautifulness and practicability into one whole.

Description

technical field [0001] The invention belongs to the field of anti-counterfeiting technology, and relates to a manufacturing method and products of a nuclear micropore track integrated anti-counterfeiting mark, in particular to a nuclear micropore anti-counterfeiting technology mainly based on a laser rainbow holographic image anti-counterfeiting technology and a nuclear micropore vacuum evaporation anti-counterfeiting technology A method for manufacturing anti-counterfeiting marks by comprehensive means supplemented by it. Background technique [0002] Comprehensive anti-counterfeiting is a direction of anti-counterfeiting technology development. Since the introduction of laser holographic image production lines in my country in the 1980s, the laser anti-counterfeiting marks produced once played an important role in the fight against counterfeiting. In the future, due to the swarms from all over the world, there are currently hundreds of manufacturers that can produce such ...
