Embodiment 1

[0033] A manufacturing process of anti-counterfeiting environmental protection transfer paper, comprising the following steps:

[0034] Use a diamond lathe to make a Fresnel lens with a central lens radius of 20cm; copy the obtained Fresnel lens structure on a PET substrate with a UV-curable coating, and then use UV-curing treatment, and the wavelength of the UV light is set to 150-300nm In between, the curing time is 0.1h; the cured PET substrate is electroplated twice in the electroforming tank to obtain a molded working board with the above-mentioned Fresnel lens structure copied. Install the molding work plate on the molding roller.

[0035] Make ultraviolet light transfer coating according to following components and parts by weight: 15 parts of methyl etherified amino resins, 10 parts of hydroxyl acrylic resins, 8 parts of polyvinyl alcohol resins, 2.3 parts of acetic acid, 5.8 parts of sodium salicylate, 26 parts of ethanol, 6 parts of n-butanol, 10 parts of isopropano...

Embodiment 2

[0051] A manufacturing process of anti-counterfeiting environmental protection transfer paper, comprising the following steps:

[0052] Use a diamond lathe to make a Fresnel lens with a central lens radius of 30cm; copy the obtained Fresnel lens structure on a PET substrate with a UV-curable coating, and then use UV-curing treatment, and the wavelength of the UV light is set to 150-300nm In between, the curing time is 0.15h; the cured PET base material is subjected to two electroplating treatments in the electroforming tank to obtain a molded working board with the above-mentioned Fresnel lens structure copied. Install the molding work plate on the molding roller.

Abstract

The invention discloses anti-counterfeiting environment-friendly transfer paper and a manufacturing process thereof. The anti-counterfeiting environment-friendly transfer paper has a Fresnel lens structure. According to a specific structure of a Fresnel lens, a novel resin coating is innovatively developed, ultraviolet-curing technology is combined with a molding process by process improvement andinnovation and by the aid of the advantages of ultraviolet-curing technology, and the anti-counterfeiting environment-friendly transfer paper with the copied Fresnel lens structure is finally obtained. Moreover, the anti-counterfeiting environment-friendly transfer paper has the advantages of clear Fresnel lens structure, good visual effect, environmental friendliness, strong anti-counterfeitingproperty and the like.

Description

technical field [0001] The invention relates to the field of special anti-counterfeiting materials, in particular to an anti-counterfeiting environment-friendly transfer paper and a manufacturing process thereof. Background technique [0002] Fresnel lenses are microstructures made up of facets that bend or reflect light like thick lenses. They can be focused or diffused. There are linear and circular Fresnel lenses. The former mirrors are concentrated on one axis and look like a cylinder; the latter look like a sphere. There are converging lenses and diverging lenses, the former focuses on the front of the lens; the latter has a virtual focus on the rear of the lens when light comes from the rear of the lens. Therefore, for two converging lenses and diverging lenses next to each other, the real focus of the former is on the film, and the virtual focus of the latter is behind the film. When moving, the two focuses are in opposite directions, which will cause visual illusi...
