Method for manufacturing nuclear hole anti-counterfeiting film of target anti-counterfeiting pattern by one-step molding

Abstract

The invention discloses a method for manufacturing nuclear hole anti-counterfeiting film of target anti-counterfeiting pattern by one-step molding, which solves the problems of complicated process, poor mechanical performance and poor anti-counterfeit strength of the anti-counterfeit film in the prior art. The method of the invention utilizes the thermal neutron absorption characteristic of the metal Gd to place a Gdmask sheet with a hollow anti-counterfeiting pattern in front of a plastic film, and then irradiates the Gdmask sheet on a thermal neutron beam to obtain an anti-counterfeiting pattern formed by combining nuclear pores on the plastic film. As the thermal neutron beam is irradiated, the nuclear hole anti-counterfeiting film pattern is prepared by one-step molding according to the thermal neutron absorption characteristic of the metal Gd. The invention raises the threshold of making the anti-counterfeit film, reduces the complexity of making the pattern of the nuclear hole anti-counterfeit film, improves the mechanical strength of the nuclear hole anti-counterfeit film, and is more convenient for application.

Description

technical field [0001] The invention belongs to the technical field of imitation counterfeiting, and in particular relates to a method for forming a nuclear hole anti-counterfeiting film with a target anti-counterfeiting pattern at one time. Background technique [0002] With the gradual improvement of people's living standards, people's demand for high-quality goods is also increasing. Therefore, counterfeit and shoddy products of high-end commodities such as milk powder, white wine, cosmetics and smart home appliances often appear in the market, so people use various anti-counterfeiting methods to prevent counterfeiting. According to the document "2016 Anti-counterfeiting Development Status and Market Prospect Analysis", after the telephone anti-counterfeiting technology was submerged by the "wave of counterfeiting technology", texture anti-counterfeiting technology came into being and became a new generation of milestone anti-counterfeiting technology. Texture anti-count...
