Problems solved by technology

[0007] 3. Chemical discoloration and anti-counterfeiting: Some components react with the chemical components in the rubber and cannot be used
[0008] 4. Watermark anti-counterfeiting: it cannot show its anti-counterfeiting characteristics when used on rubber
[0009] 5. Moisture sensitive (drip anti-counterfeiting) anti-counterfeiting: It can only be used on paper products because the rubber is not soaked in water and cannot be used in rubber
[0010] 6. Magnetic anti-counterfeiting: special tools need to be used for inspection, and most customers do not have special tools
[0015] Its disadvantage is that it is not a special transfer label for rubber and cannot be combined with rubber products.

Embodiment 1

[0038] An optically variable anti-counterfeit label for rubber products, comprising a polyester film on which anti-counterfeit ink is reverse-printed, and the anti-counterfeit ink is composed of the following components: 1 kg of zinc oxide, 2 kg of alkyd resin, and 1.4 kg of rosin , 5 kg of catalpa oil, 0.5 kg of paraffin, 0.45 kg of cobalt naphthenate, 10 kg of glue, 40 kg of gasoline, and 7.2 kg of interference-type optical variable powder.

[0039] The mortar is prepared by sizing material, gasoline and thinner according to the ratio of 1:1.5:1.5.

[0040] The diluent is 719 quick-drying agent.

[0041] The rubber material is composed of natural rubber, zinc oxide, stearic acid, 2-mercaptobenzimidazole, 2-mercaptobenzothiazole, dibenzothiazole disulfide, soybean oil, and styrenated diphenylamine, and its weight ratio is 100 :4:3:2.3:1:1.8:4:0.4.

[0042] A method for making an optically variable anti-counterfeit label for rubber products, comprising the following steps: ...

Embodiment 2

[0050] The difference between this embodiment and embodiment 1 is that 783 slow-drying agent is selected as the diluent.

Embodiment 3

[0052] The difference between this embodiment and Embodiment 1 is that 7.2 kg of interference type optical variable powder is replaced by 11 kg of liquid crystal type optical variable powder.

[0053] In the above embodiments, both the interference type optical variable powder and the liquid crystal type optical variable powder are products of Guangzhou Mingbo Anti-Counterfeiting Technology Co., Ltd. The optical variable anti-counterfeiting material of Chengdu Jinghe Optoelectronics Technology Co., Ltd. is not as effective as the products of Guangzhou Mingbo Anti-counterfeiting Technology Co., Ltd.

[0054] The types of interference-type light-changing powders are: silver to green, red to green, purple to green, brown to gold, magenta to gold, rose red to gold, yellow to blue, grass green to blue, blue to purple, cyan to blue Purple, gold to silver.

[0055] The types of liquid crystal light-changing powders are: gold-to-green, red-to-green, green-to-blue, blue-to-purple-blac...

Abstract

The invention relates to the technical field of rubber product security, in particular to an optical chromatic security label of a rubber product and a manufacturing method thereof. The security label comprises a polyester film, wherein security ink is printed on the polyester film in a reversed phase. The security ink comprises the following components such as zinc oxide, alkyd resin, colophony, catalpa oil, paraffin, cobalt naphthenate, mucilage, petrol and interference-type light variable powder in a corresponding weight ratio of 1:2:1.4:5:0.5:0.45:10:40:7.2. Compared with the prior art, in the optical chromatic security label of the rubber product and the manufacturing method thereof, the security label can be directly vulcanized on the rubber product, so that the problem of the falling of a non-setting adhesive security trademark is solved; and the light variable performance is stable after a high temperature and a high pressure.

Description

technical field [0001] The invention relates to the technical field of anti-counterfeit rubber products, and specifically provides an optically variable anti-counterfeit label for rubber products and a manufacturing method thereof. Background technique [0002] Optically variable ink was first researched by Canada in 1975, and successfully developed a light interference multilayer composite film, which proved that this multilayer film can selectively absorb and reflect composite light. The United States began to develop thin-film filters with the same principle in 1981. In 1984, it developed a method of transferring the film to other surfaces, and applied for a patent for making an optically variable film whose coating color changes with the viewing angle. Afterwards, a security ink company in Switzerland adopted the invention and launched the optical variable product at the Seventh International Banknote Anti-counterfeiting Conference in June 1987, and then the optical vari...
