Embodiment 1

[0011] Example 1: 12.3g (13ml) of water-based polyurethane, 6g of up-conversion 980nm infrared-excited visible green phosphor, 1g of pure phenolic resin oil, 1g of polyethylene wax, 0.5g of mineral oil, and 0.2g of super-concentrated paste. Among them, super-concentrated pulp is a commercially available chemical raw material (its trade name is: super-concentrated pulp, produced by Tianjin Caimei Dyestuff Chemical Co., Ltd. (formerly Tianjin No. 8 Dyestuff Factory))

[0012] The preparation method is as follows: first pour 13ml of water-based polyurethane, add 6g of up-conversion 980nm infrared-excited visible green phosphor, 1g of super-concentrated paste, 1g of pure phenolic resin oil, 0.5g of polyethylene wax; 0.2g of mineral oil; use a magnetic stirrer Stir it evenly, then add it to a three-roll grinder to grind the material, and finally use a disperser to adjust its viscosity, and then add 4-5 drops of water-based color paste to make water-based stamp ink.

Embodiment 2

[0013] Example 2: 65g of water-based polyurethane, 18g of up-conversion 980nm infrared-excited visible green fluorescent powder, 3g of super-concentrated paste, 6g of pure phenolic resin oil, 6g of polyethylene wax; 2g of mineral oil.

[0014] The preparation method is the same as in Example 1.

Embodiment 3

[0015] Example 3: 70g of water-based polyurethane, 15g of up-conversion 980nm infrared-excited visible green fluorescent powder, 2g of super-concentrated paste, 5g of pure phenolic resin oil, 5g of polyethylene wax; 3g of mineral oil.

[0016] The preparation method is the same as in Example 1.

[0017] The above-mentioned infrared up-conversion phosphor is a high-tech material and is an Er 3+ / Yb 3+ The overlap integral of the normalized fluorescence linear function of the donor ion and the normalized absorption linear function of the acceptor ion in the four glass matrices of co-doped silicate, germanate, phosphate and fluoride, the cross-relaxation probability, by Solve the energy level transition rate equation, get 4S 3 / 2 The relative population of energy levels, which defines the upconversion luminous efficiency can be used with the spontaneous emission transition probability A61 and 4S 3 / 2 It is characterized by the product of the relative population number of the ene...

Abstract

The invention discloses an aqueous anti-counterfeiting stamp ink with stronger anti-counterfeiting performance. The aqueous anti-counterfeiting stamp ink comprises the following components in percentage by weight: 60%-70% of aqueous polyurethane, 15%-25% of infrared transformed fluorescent powder, 1%-2% of super-concentrated slurry, 6%-8% of light calcium carbonate, 6%-8% of polyethylene wax and 2%-4% of mineral oil. The aqueous anti-counterfeiting stamp ink has the advantages of stable stamping performance, good detection on information provided by anti-counterfeiting feature substances, long-term preservation and rapid and accurate true and false discrimination by adopting a discriminating system for collecting stamp features.

Description

technical field [0001] The invention relates to the field of anti-counterfeiting printing ink materials, and more specifically relates to a water-based printing ink with strong anti-counterfeiting properties. Background technique [0002] Ink ink includes ink pad, ink pad ink and atomic ink (including penetrating type and solid type). The anti-counterfeiting of printing ink is realized by adding detectable substances in printing ink. At present, the relatively successful printing ink anti-counterfeiting technologies include: [0003] UV fluorescent ink, optical color-changing ink, temperature-changing ink, humidity-sensitive ink, infrared excitation ink, solar color-changing ink, watermark ink, magnetic ink, hollow damage ink, chemical color-changing ink, pressure-sensitive color-changing ink, mirror image color-changing ink, etc. [0004] For ordinary printing inks, the above-mentioned printing inks have strong anti-counterfeiting properties. However, once the correspondi...
