Embodiment 1

[0042] A preparation method of three-dimensional anti-counterfeiting paper, the process is as follows figure 1 shown, including the following steps:

[0043] (1) make face paper layer slurry, core paper layer slurry and face paper layer slurry respectively;

[0044] (2) loading the anti-counterfeit mark on the carrier to obtain the anti-counterfeit layer;

[0045] (3) After the surface paper layer slurry, core paper layer slurry and bottom paper layer slurry prepared in step (1) are respectively filtered, the anti-counterfeiting layer obtained in step (2) is added to the core paper layer slurry , and then perform three-layer composite to obtain a composite slurry with a thickness of 150-400 μm;

[0046] (4) After the paper sheet is formed, it is pressed and dried for the first time, then the surface is sizing, and then it is coated and dried for the second time, and then coiled and packaged to obtain a three-dimensional anti-counterfeiting white cardboard;

Abstract

The invention provides a preparation method of three-dimensional anti-counterfeiting paper. Firstly, the surface paper layer slurry, the core paper layer slurry and the surface paper layer slurry are respectively prepared, the anti-counterfeiting mark is loaded on the carrier to obtain the anti-counterfeiting layer, and the anti-counterfeiting layer is Add it to the core paper layer slurry, and then compound the core paper layer slurry with the surface paper layer slurry and the surface paper layer slurry. After the paper sheet is formed, it will be pressed and dried for the first time. After drying for the second time, it is coiled and packaged to obtain three-dimensional anti-counterfeiting paper, and the carrier is glutinous rice paper. The invention adopts biomass-degradable glutinous rice paper as a carrier, and arranges the anti-counterfeiting marks in three-dimensional and irregular arrangement on the paper by adjusting the melting speed and temperature, so as to ensure the anti-counterfeiting technology without affecting each physical index of the paper. The non-reproducibility of anti-counterfeiting reduces the cost of anti-counterfeiting and the uncontrollability of anti-counterfeiting marks. It does not require modification of equipment or special treatment of slurry, and will not affect the physical properties and printing adaptability of the paper.

Description

technical field [0001] The invention belongs to the technical field of papermaking, and in particular relates to a preparation method of three-dimensional anti-counterfeiting white cardboard. Background technique [0002] In order to prevent their products from being counterfeited, various commodity manufacturers mostly use anti-counterfeiting paper to package and anti-counterfeit their products. Enterprise users fight against counterfeit products, eliminate mass imitation, protect corporate brand, maintain corporate image, and avoid economic losses. At present, the technologies used in the production of anti-counterfeiting paper are mainly printing anti-counterfeiting technology and pulp anti-counterfeiting technology. [0003] In printing anti-counterfeiting technology, ink is an important part of anti-counterfeiting. Anti-counterfeiting inks can be roughly divided into fluorescent inks, magnetic inks, etc. The biggest disadvantage of inks attached to the surface of the ...
