The waterproof film layer forms a physical waterproof barrier, further reducing water erosion. The polyurethane fiber layer, coated with water-based polyurethane, enhances its flexibility and bending resistance. A nano-waterproof coating forms a nano-level waterproof barrier, significantly reducing the retention and penetration of moisture on the label surface and improving its waterproof performance. This multi-layered waterproof design ensures that the label remains clear and structurally intact even under prolonged rain, immersion, or other humid conditions.

[0013] This waterproof paper label features a protective layer with excellent optical properties, high transparency, and gloss during daily use. It also prevents external physical damage and light aging.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a technical solution: a waterproof paper label, including an erasable layer 1, which carries text, patterns, barcodes, QR codes, and other information to achieve the label's identification and information transmission functions. Content can also be written on its surface. Its surface is coated with a nano-silica hydrophobic layer to ensure waterproofing. A protective layer 2 is fixedly installed at the bottom of the erasable layer 1. The protective layer 2 is made of polypropylene, has a smooth surface, good optical properties, high transparency and gloss, and a certain degree of scratch and abrasion resistance. It mainly serves a physical protection function, preventing the label surface from being scratched or worn, and also preventing external moisture from directly contacting the underlying structure, thus protecting the label as a whole. A plant fiber layer 3 is fixedly installed at the bottom of the protective layer 2. The plant fiber layer 3 is impregnated with an organosilicon waterproofing agent to provide basic waterproofing. A waterproof film layer 4 is fixedly installed at the bottom of the plant fiber layer 3, forming a physical waterproof barrier to further reduce water penetration. The bottom of the waterproof film layer 4 is fixedly installed with a polyurethane fiber layer 5. The polyurethane fiber layer 5 is a fiber layer coated with water-based polyurethane, which enhances its flexibility and bending resistance. The bottom of the polyurethane fiber layer 5 is fixedly installed with a nano waterproof coating 6. The nano waterproof coating 6 is made of a mixture of nano titanium dioxide and organosilicon. The nano titanium dioxide in the nano waterproof coating 6 has superhydrophobic properties, while the organosilicon enhances the flexibility and adhesion of the coating, forming a nano-level waterproof barrier. Water droplets will form water beads and roll off its surface, greatly reducing the retention and penetration of water on the label surface and improving the label's waterproof performance. The bottom of the nano waterproof coating 6 is fixedly installed with a polyimide film layer 7. The polyimide film layer 7 has extremely high heat resistance and requires a high temperature to decompose, thus achieving the purpose of high temperature resistance. The bottom of the polyimide film layer 7 is fixedly installed with an aerogel heat insulation felt layer 8. The aerogel heat insulation felt layer 8 has a low thermal conductivity and can block heat conduction to the interior of the label.

[0021] A modified silicone paper layer 9 is fixedly installed at the bottom of the aerogel insulation felt layer 8. The surface of the modified silicone paper layer 9 is coated with a high-temperature pressure-sensitive adhesive, which can maintain adhesion in high-temperature environments. A substrate layer 10 is fixedly installed at the bottom of the modified silicone paper layer 9. The substrate layer 10 is made of polymer materials such as polyolefin resin, combining the printability of paper with the waterproof, moisture-proof, and tear-resistant properties of plastic. It provides the label with basic strength and stiffness, ensuring that the label is not easily deformed or damaged during processing and use. At the same time, its own waterproof properties further enhance the waterproof ability of the label. An adhesive layer 11 is fixedly installed at the bottom of the substrate layer 10. The adhesive layer 11 has the characteristics of strong adhesion, good temperature resistance, and anti-aging, and can maintain good adhesion performance in different temperature and humidity environments. An anti-counterfeiting coating 12 is fixedly installed at the bottom of the adhesive layer 11. An adhesive backing layer 13 is fixedly installed at the bottom of the anti-counterfeiting coating 12. The adhesive backing layer 13 is made of acrylic pressure-sensitive adhesive, which has the characteristics of strong adhesion, good temperature resistance, and anti-aging, and can maintain good adhesion in different temperature and humidity environments. The adhesive layer 13 maintains good adhesion, allowing the label to adhere firmly to various surfaces such as metal, plastic, glass, and paper, and it is not easy to fall off after application. It also has a certain degree of water resistance, preventing moisture from seeping in from the label edges. A release layer 14 is fixedly installed at the bottom of the adhesive layer 13. The surface of the release layer 14 is coated with an organic silicone coating, which has good anti-stick properties. Before use, it protects the adhesive layer 11 and facilitates label peeling and pasting. The material of the adhesive layer 13 is acrylic pressure-sensitive adhesive, which is a pressure-sensitive adhesive with acrylic ester monomers as the main component. It does not require solvents or heating and only requires light pressure to achieve bonding. It has good low-temperature resistance and high-temperature resistance, and can maintain a stable bonding effect at extreme temperatures. The material of the release layer 14 is glassine paper, which is a semi-transparent special paper made by coating glassine base paper. It has high temperature resistance, moisture resistance, and oil resistance. It has excellent waterproof and moisture-proof performance and can effectively protect the label from moisture and grease contamination.

[0022] Working principle: First, the plant fiber layer 3 is impregnated with an organosilicon waterproofing agent, providing basic waterproofing. The waterproof film layer 4 forms a physical waterproof barrier, thereby reducing water erosion. The polyurethane fiber layer 5 is a fiber layer coated with water-based polyurethane, enhancing its flexibility and bending resistance. Then, a nano-waterproof coating 6 forms a nano-level waterproof barrier, greatly reducing the retention and penetration of water on the label surface and improving the label's waterproof performance. Second, the protective layer 2 has good optical properties, high transparency and gloss, and can also prevent external physical damage and photoaging. The polyimide film layer 7 has extremely high heat resistance, requiring a high temperature to decompose, thus achieving high temperature resistance. The aerogel heat insulation felt layer 8 has a low thermal conductivity, which can block heat conduction to the inside of the label. The surface of the modified silicone paper layer 9 is coated with a high-temperature pressure-sensitive adhesive, which can maintain adhesion in high-temperature environments, making it suitable for use in complex environments. Finally, the content can be written on the surface of the erasable layer 1 and pasted onto the surface of the object through the adhesive layer 11.
