Anti-counterfeiting material and preparation method thereof

Abstract

The invention relates to anti-counterfeiting technologies, particularly to an anti-counterfeiting material and a preparation method thereof. The anti-counterfeiting material adopts a flake-like structure which is formed through connecting two or more ultraviolet fluorescence modules. The preparation method comprises the steps of S110, providing a glass substrate; plating the glass substrate with an adhesive layer; plating the adhesive layer with a sacrificial layer; coating the sacrificial layer with a mixture of ultraviolet fluorescent powder and light curing glue; providing an ultraviolet light source, providing a first submergence template, and exposing the mixture coating; carrying out development; carrying out cleaning; coating the sacrificial layer with the mixture of ultraviolet fluorescent powder and light curing glue for the Nth time; providing the Nth submergence template, and exposing the mixture coating; carrying out development; carrying out cleaning; completing the arrangement of all the ultraviolet fluorescence modules; etching the sacrificial layer; carrying out cleaning; and carrying out filtration. The invention provides the anti-counterfeiting material which has multiple functions and is uneasy to imitate and the preparation method thereof.

Description

technical field [0001] The invention relates to anti-counterfeiting technology, in particular to an anti-counterfeiting material and a preparation method thereof. Background technique [0002] In the anti-counterfeiting technology of the prior art, watermarks, colored fibers, fluorescent ink printing, shapes and random distribution of micro-dots or tiny marks are mostly used as anti-counterfeiting means. [0003] For example, prior art 1, Chinese patent document CN102108653A, discloses a sheet-shaped anti-counterfeiting material, the sheet-shaped anti-counterfeiting material adopts a special-shaped structure other than a regular quadrilateral; and the sheet-shaped anti-counterfeiting material is composed of the following layered structure: paper A quality anti-counterfeiting carrier layer, wherein the paper-based anti-counterfeiting carrier is paper manufactured by compounding at least two kinds of fibers; and an anti-counterfeiting layer. Also disclosed are a preparation m...

AI Technical Summary

Problems solved by technology

[0007] However, such as listed above, the prior art composite fibers, fluorescent silicon nanoparticles, micro-dots or micro-mark shapes and random distribution as anti-counterfeiting means are not the effect that can prevent others from forging as described in the open text. With the advancement of science and technology, these technical means can be imitated cheaply. The only thing that cannot be imitated is the background database described in prior art 3, but the background data is not safe. Enterprise databases are easily attacked by hackers, and communication security is required. Still not ideal

Therefore, the anti-counterfeiting materials and anti-counterfeiting means of the prior art have more or less potential safety hazards, and need to be constantly updated and improved.
