Anti-counterfeiting tape is a technology used to ensure product authenticity and protect consumer rights. It's widely used in various packaging materials. It not only protects the integrity of goods but also plays an important role in preventing counterfeiting in logistics, transportation, document packaging, and other fields. Adhesive is used in anti-counterfeiting tape.

[0003] Existing technology typically involves wrapping the outer surface of an anti-counterfeiting label with transparent tape and adhering it to the surface of an item.

[0022] (3) Prepare the base layer, select kraft paper as the tape base layer, dry the base layer, and apply the coating material on the surface of the base layer to form a coating layer; (4) preparing a non-woven fabric and printing the anti-counterfeiting information on the non-woven fabric as a printing layer, and laminating the non-woven fabric printed with the anti-counterfeiting information on the side of the adhesive layer away from the kraft paper; (5) Applying a protective paint on the side of the printed layer away from the adhesive layer, and drying the protective paint to form a protective paint layer; (6) Dry and collect to obtain the anti-counterfeiting tape, Among them, in step S4, the proportion of the protective paint layer is: 30-40 parts of acrylic acid, 50-55 parts of polyurethane, 40-45 parts of epoxy resin, 20-25 parts of quartz sand, 10-13 parts of calcium powder, 2-5 parts of dispersant, 3-6 parts of foaming agent, 2-5 parts of thickener, and 15-20 parts of water.

[0023] The curing agent is any one of organic acid anhydrides, imidazoles, organic amines, and polymers.

[0024] Wherein, in step S3, the temperature of the high temperature reaction is 240-260° C., the time is 90 min, and the pressure is lower than 2.5 MPa.

[0025] In step S6, the grinding machine performs grinding, the cooling water temperature in the grinding machine is maintained at 5-20° C., and the grinding rate is 5-10 L / min.

[0026] In step S7, the stirring is magnetic stirring, and the parameters of the magnetic stirring are: temperature 50-70°C, speed 700-900 r / min, and time 2-3 hours. Wherein, in step S8, the drying temperature is 40° C. and the drying time is 4-6 hours.

[0027] Wherein, in step (5), the drying temperature is 20-30°C and the drying time is 24 hours.

[0028] Among them, the anti-counterfeiting tape of the present invention uses innovative materials as the glue layer in the ordinary anti-counterfeiting tape to improve the high temperature resistance of the tape as a whole, has environmental protection and non-toxic characteristics, adds a curing agent to the glue layer material to increase the characteristics of the glue layer material, so that its intermolecular distance, morphology, thermal stability, and chemical stability are all improved, shortening the curing time and curing temperature of the colloid, the overall glue layer uses H3PO4 and aluminum hydroxide as the main materials, phosphoric acid provides higher adhesion for the glue layer, aluminum hydroxide improves the overall high temperature resistance, and a protective paint layer is applied to the outermost layer of the anti-counterfeiting tape to increase the wear resistance of the printed layer anti-counterfeiting information, thereby improving the service life of the tape as a whole, after the anti-counterfeiting tape is affixed, as the adhesive solidifies, the reaction gradually slows down, and when the glue layer is fully solidified, the reaction stops. The result of the reaction is that the surface of the sticker partially dissolves, and simultaneously produces the deposition of metallic copper, forming a mutually penetrating transition layer on the sticker surface, so that the sticker and the adhesive are tightly combined on the sticker surface, thereby increasing the bonding strength. After high-temperature treatment, a copper oxide layer forms on the surface. The copper oxide acts as a "bridge" between the adhesive and the adhered material, allowing them to bond tightly together and enhancing the bond strength. Within the adhesive, copper oxide is a discrete phase, serving as a foundation for the growth of hydrogen phosphate, forming a star-shaped aggregate that interpenetrates and holds the entire adhesive together. Aluminum phosphate adhesives are acidic mixtures composed of phosphoric acid (aluminum dihydrogen phosphate (Al(H2PO4)3)), water, and phosphoric acid. Aluminum dihydrogen phosphate is a thermosetting binder that forms a strong bond with oxides. Concentrated phosphoric acid primarily forms a structure based on PO4 tetrahedrons, connected by oxygen bridges to form a polyphosphate mixture. As the temperature rises, the degree of polymerization (n) increases, forming a large molecular network structure.
