Preparation method of fluorescent anti-counterfeiting self-adhesive paper

Abstract

The invention discloses a preparation method of fluorescent anti-counterfeiting self-adhesive paper, which comprises the following steps: material preparation, film spraying, release agent coating, primary gluing, fluorescent fiber pre-embedding, secondary gluing, compounding and slitting to obtain a fluorescent anti-counterfeiting self-adhesive paper finished product. The gluing interval cannot exceed the alarm time, the gluing amount does not fluctuate greatly, the thickness is controlled to be 2 mm, drying is conducted through a drying oven, a semi-finished adhesive paper product is obtained, the obtained semi-finished adhesive paper product is glued again, the proportion is strictly adjusted according to the technological conditions before gluing, the error is not larger than 2%, and then the self-adhesive paper product is obtained. Therefore, the anti-counterfeiting fluorescent fiber is protected between the gluing layers in the preparation process of the self-adhesive paper, the stability of the anti-counterfeiting fluorescent fiber is higher, the damage and denaturation of the anti-counterfeiting fluorescent fiber are reduced, and the practicability of the fluorescent anti-counterfeiting self-adhesive paper is improved.

Description

technical field [0001] The invention relates to the field of preparation methods of fluorescent anti-counterfeit self-adhesive paper, in particular to a preparation method of fluorescent anti-counterfeit self-adhesive paper. Background technique [0002] Anti-counterfeiting self-adhesive refers to the use of multiple processes such as printing, printing, and inkjet on ordinary self-adhesive paper, so that the printed product has anti-counterfeiting functions. Ordinary self-adhesive materials are mainly composed of bottom paper, adhesive layer, printing Anti-counterfeiting technology is generally applied on the printing layer. In recent years, the civilian use of special anti-counterfeiting paper has also provided a good opportunity for self-adhesive anti-counterfeiting. Metal wire anti-counterfeiting paper, watermark anti-counterfeiting paper and other materials are coated and processed. Ideal anti-counterfeiting self-adhesive materials, the specific manifestations of anti-c...

Problems solved by technology

[0003] In the prior art, during the production process of fluorescent anti-counterfeiting self-adhesive paper, anti-counterfeiting fluorescent fibers are added to the surface of the surface material or the surface of the adhesive layer, so that the anti-counterfeiting fluorescent fibers are prone to fading or denaturation due to unstable contact surfaces. Hidden dangers, reduce the anti-counterfeiting effect of self-adhesive paper, therefore need a kind of preparation method of fluorescent anti-counterfeiting self-adhesive paper
