[0002] Traditional anti-counterfeiting labels, such as product tags, business cards, and QR code labels, are transferred to the surface of items through printing or pasting to protect the target product. However, most anti-counterfeiting labels have limited functions, are expensive to manufacture, and are prone to causing environmental pollution, thus limiting their wider application.
[0003] Currently, due to the advantages of printed electronic products such as low cost, resource conservation, green environmental protection, flexibility, and large-scale production, paper-based anti-counterfeiting labels have received increasing attention in recent years. In addition, they also have the advantages of being environmentally friendly and biodegradable, thus having broad application prospects. However, existing paper-based anti-counterfeiting labels are limited to pattern anti-counterfeiting, making their functions relatively simple. Therefore, further research and development are needed to give them multiple functions. Summary of the Invention
[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a paper-based integrated sound and color anti-counterfeiting label and its full printing production method, which has both pattern anti-counterfeiting and sound anti-counterfeiting functions.
[0005] To achieve the above objectives, the present invention employs the following technical solution:
[0006] A paper-based integrated sound and color anti-counterfeiting label includes a paper substrate, a display unit, conductive lines, and a sound unit;

[0011] Furthermore, the paper substrate is digital proofing paper or coated paper.
[0012] Furthermore, the conductive polymer ink is prepared by the following method:

[0016] Furthermore, the ion storage layer is prepared by the following method:
[0017] Perchlorate, polydimethylsiloxane and deionized water were mixed in a mass ratio of (1-3):1:(10-15), heated and stirred in a water bath at 90°C for 1 hour, and ultrasonically dispersed to eliminate bubbles to obtain perchlorate hydrogel. The perchlorate hydrogel was then uniformly coated onto the surface of the conductive electrode layer to form an ion storage layer.
[0018] The perchlorate is LiClO4, Zn(ClO4)2 or Al(ClO4)3.
[0019] Furthermore, the counter electrode layer is a zinc foil or a copper foil.
[0020] Furthermore, the voltage polarization layer is prepared by the following method:
[0021] According to the mass ratio of (1~3):(3.5~4.5):(3.5~4.5), substance A, dimethyl sulfoxide and deionized water are mixed and heated and stirred in a water bath at 90℃ for 1 hour. The mixture is then ultrasonically dispersed to eliminate bubbles, and the voltage polarization layer material is obtained. The voltage polarization layer material is then uniformly coated on the surface of the bottom conductive electrode layer to form a voltage polarization layer.
[0022] The substance A is PVA, PEO, or PDMS.
[0023] A method for producing a paper-based integrated sound and color anti-counterfeiting label includes the following steps:
[0024] Step 1: Mix 1.3% (w / w) of poly(3,4-ethylenedioxythiophene)-polystyrene sulfonic acid aqueous solution and acetone at a mass ratio of (90-95):(5-10) to obtain mixed solution B; mix mixed solution B and butanol at a mass ratio of (90-95):(5-10) and stir at room temperature for 12 hours to obtain conductive polymer ink;
[0025] Step 2: According to the designed anti-counterfeiting pattern, use gravure printing to print conductive polymer ink on different areas of the paper substrate surface. Anneal at 90-120℃ for 20-30 minutes to form a conductive electrode layer and a bottom conductive electrode layer.
[0026] Step 3: Dip the electrode into acetic acid solution or ethanol solution and apply it to the surface of the conductive electrode layer and the bottom conductive electrode layer. Dry at room temperature for 10 to 30 minutes.
[0027] Step 4: Use screen printing to print conductive silver paste on the surface of the paper substrate to form two conductive lines.

Dry at 120°C for 20 minutes.
[0028] Step 5: Mix perchlorate, polydimethylsiloxane and deionized water in a mass ratio of (1-3):1:(10-15), heat and stir in a water bath at 90°C for 1 hour, and ultrasonically disperse to eliminate bubbles to obtain perchlorate hydrogel.

[0029] Step 6: Take substance A, dimethyl sulfoxide and deionized water in a mass ratio of (1-3):(3.5-4.5):(3.5-4.5), heat and stir in a water bath at 90°C for 1 hour, and ultrasonically disperse to eliminate bubbles to obtain voltage polarization layer raw material.

[0032] Step 8: Using gravure printing, conductive polymer ink is printed on the surface of the voltage polarization layer to form a top conductive electrode layer, which is connected to the other end of the first conductive line.
[0033] Furthermore, the gravure printing in step 2 uses a printing speed of 0.1–0.3 m / s, a printing pressure of 600–700 N, a gravure cell depth of 50 μm, a screen angle of 53°, and a screen ruling of 175 l / in.
[0034] Furthermore, the perchlorate in step 5 is LiClO4, Zn(ClO4)2, or Al(ClO4)3.
[0035] Compared with the prior art, the present invention has the following technical effects:
[0036] When the conductive electrode layer and the counter electrode layer come into contact, a chemical reaction occurs between the ion storage layer and the counter electrode layer, converting chemical energy into electrical energy. This not only causes a color change in the anti-counterfeiting pattern on the display unit, but also transmits electrical energy through the conductive circuit to the sound unit connected in series with the display unit. The thin-film voltage polarization layer deforms and vibrates to produce sound, thus achieving dual anti-counterfeiting through sound and pattern, improving the anti-counterfeiting effect. When the conductive electrode layer and the counter electrode layer separate, the display unit hides the pattern and stores energy internally. It can be seen that the paper-based sound and color integrated anti-counterfeiting label of the present invention is not only simple in structure, but also integrates energy conversion, storage and consumption. When applied to product packaging, it is more convenient and intelligent, enhancing consumers' desire to purchase the product.
[0037] By employing gravure printing, the conductive electrode layers of the display unit and sound unit are prepared in one printing process using the same conductive polymer ink. The conductive lines are printed using screen printing, and the ion storage layer and voltage polarization layer are printed using a scraping method. This achieves large-scale, full-printing of anti-counterfeiting labels, making the manufacturing process more efficient and cost-effective.
[0038] This invention uses digital proofing paper or coated paper as the paper substrate, which is different from traditional PET and PEN substrates and has advantages such as being green and environmentally friendly, recyclable, low cost and flexible. Attached Figure Description

[0043] The specific content of the present invention will be further explained in detail below with reference to the embodiments.
[0044] like Figures 1-3 As shown, a paper-based integrated sound and color anti-counterfeiting label includes a paper substrate 1, a display unit 2, a conductive circuit 3, and a sound unit 4;
[0045] The display unit 2 includes a conductive electrode layer 5 printed on the surface of a paper substrate 1. An ion storage layer 6 is coated on the surface of the conductive electrode layer 5, and a counter electrode layer 7 is adhered on the ion storage layer 6. The area of the ion storage layer 6 is smaller than the area of the conductive electrode layer 5 and the counter electrode layer 7. When verifying authenticity, the edges of the conductive electrode layer 5 and the counter electrode layer 7 are brought into contact, and a chemical reaction occurs between the ion storage layer 6 and the counter electrode layer 7: Zn → Zn 2+ +2e - ;PEDOT + PSS - +Li + +e - →PEDOT 0 +Li + :PSS - The chemical energy is converted into electrical energy, and the display unit 2 changes from light blue to dark blue, which serves as an anti-counterfeiting feature.
[0046] The sound unit 4 includes a bottom conductive electrode layer 8 printed on the surface of a paper substrate 1, a voltage polarization layer 9 coated on the surface of the bottom conductive electrode layer 8, and a top conductive electrode layer 10 printed on the surface of the voltage polarization layer 9.
[0047] There are two conductive lines 3. One end of the first conductive line 3 is connected to the conductive electrode layer 5, and the other end is connected to the top conductive electrode layer 10. One end of the second conductive line 3 is connected to the conductive electrode layer 8, and the other end is connected to the top conductive electrode layer 10. This connects the display unit 2 and the sound unit 4. The electrical energy generated by the chemical reaction of the display unit 2 is transmitted to the sound unit 4 through the conductive line 3. The thin-film voltage polarization layer 9 deforms and vibrates, emitting sound, which serves as a sound anti-counterfeiting measure. When the conductive electrode layer 5 of the display unit 2 separates from the counter electrode layer 7, the display unit 2 stores internal energy. At this time, the color changes from dark blue to light blue. At the same time, the sound unit 4 stops working. It can be seen that the paper-based sound and color integrated anti-counterfeiting label produced by full printing in this embodiment can realize the integration of energy conversion, storage and consumption. When applied to product packaging, it makes the product more intelligent.
[0048] Preferably, the conductive electrode layer 5 is a SUST anti-counterfeiting pattern formed by printing conductive polymer ink onto the surface of the paper substrate 1 using gravure printing, with a length of 50-80mm and a width of 20-40mm.
[0049] Preferably, the ion storage layer 6 has a length of 50-80 mm, a width of 20-40 mm, and a thickness of 0.5-0.8 mm.
[0050] Preferably, the bottom conductive electrode layer 8 and the top conductive electrode layer 10 have a length of 50-80 mm, a width of 20-40 mm, and an effective overlap area of 8-28 cm². 2 The thickness of the voltage polarization layer 9 is 0.5–0.8 mm.
[0051] Preferably, the paper substrate 1 is digital proofing paper or coated paper.
