Anti-counterfeit paper product production method

Abstract

The invention discloses an anti-counterfeit paper product preparation method. The method comprises the following steps: 1) an anti-counterfeit material is mixed with an adhesive and a medium to obtain an anti-counterfeit material mixture; wherein the anti-counterfeit material is in a powder state or a liquid state; 2) an electrically controlled injection apparatus having an injection pipe and an injector is filled with the anti-counterfeit material mixture obtained in the step 1), a paper machine is operated, the anti-counterfeit material mixture is applied in a preset paper of a paper product by the injector, wherein the paper applied with the anti-counterfeit material mixture is an application layer; 3) during a paper machine operation process, the application position of the anti-counterfeit material mixture is a wet position or a glue applying part; and 4) the product is dried. The anti-counterfeit paper product can enhance the anti-counterfeit effect in the prior art, and can reach a directional function, the preparation method is simple and convenient, and is easy to popularize and use.

Description

technical field [0001] The invention belongs to the field of paper products, and in particular relates to a preparation method of anti-counterfeit paper products. Background technique [0002] The anti-counterfeiting methods of paper-based products can be roughly divided into physical and chemical methods in terms of identification principles, such as watermarks in banknotes, anti-counterfeiting threads, anti-counterfeiting fibers that can be seen directly by the naked eye, laser holography of credit cards, invisible barcodes of commodities, etc. It belongs to the physical anti-counterfeiting method, and the chemical anti-counterfeiting method is to reveal the product characteristics by checking the chemical reaction of the anti-counterfeiting components under certain conditions to cause a certain change (such as the color change of a specific part). [0003] The anti-counterfeiting measures that are widely used in paper base mainly include anti-counterfeiting fibers, anti-c...

Problems solved by technology

[0007] In recent years, with the development of high technology, more convenient anti-counterfeiting materials have been applied in paper identification technology, but limited by the base material, anti-counterfeiting materials are poorly combined with paper and easily fall off from the paper; while printing The printing method of printing ink or spraying other ink-based anti-counterfeiting materials on the surface of paper products has many limitations and cannot be easily positioned. This affects the anti-counterfeiting function and anti-counterfeiting effect of special paper products such as banknote paper to a certain extent, and affects the product quality. quality
