[0024] Example:

[0025] As attached Figure 1 To be continued Figure 2 As shown:

[0026] This utility model provides a semi-conductive natural PP sheet, including a sheet body 1 and a protective film 2. The protective film 2 is adhered to the surface of the sheet body 1. The sheet body 1 includes a substrate layer 3, a reinforcing layer 4, a flame retardant layer 5, and a semi-conductive layer 6. The reinforcing layer 4 is disposed on the surface of the substrate layer 3, the flame retardant layer 5 is disposed on the surface of the reinforcing layer 4, and the semi-conductive layer 6 is disposed on the surface of the flame retardant layer 5. The protective film 2 includes a thin film layer 7, a moisture-proof layer 8, and a UV-resistant layer 9. The moisture-proof layer 8 is disposed on the surface of the thin film layer 7, and the UV-resistant layer 9 is disposed on the surface of the moisture-proof layer 8.

[0027] The substrate layer 3 is made of polypropylene, which has strong resistance to various chemicals such as acids, alkalis, salts, and solvents. This makes it suitable for environments requiring resistance to chemical corrosion, and polypropylene also has good tensile strength, rigidity, and abrasion resistance.

[0028] Among them, the reinforcing layer 4 is made of carbon nanotubes. The structure of carbon nanotubes gives them very high mechanical strength and rigidity. In addition, carbon nanotubes are lightweight. Furthermore, when carbon nanotubes are used as thin layers, they usually do not affect the transparency and color of the sheet body 1.

[0029] Among them, the flame retardant layer 5 is made of nano-silicon. Nano-silicon can form a stable protective silicon oxide film at high temperatures. This film can effectively isolate oxygen from the contact between the burning material and inhibit the spread of flame.

[0030] Among them, the semiconductive layer 6 is made of polyaniline. Compared with other organic conductive materials, polyaniline has high chemical stability, especially in air and humid environments, where it has good oxidation stability. In addition, polyaniline not only has good conductivity, but is also an excellent electromagnetic shielding material.

[0031] Among them, the film layer 7 is made of polyethylene. Polyethylene has good tensile strength, tensile strength and flexibility, and can withstand a certain amount of external force without easily breaking, effectively protecting the covered items from physical damage.

[0032] Among them, the moisture-proof layer 8 is made of aluminum foil. Aluminum foil has excellent barrier properties and can effectively block the penetration of water vapor, gas, light and oxygen, preventing moisture from entering the packaging or protective layer.

[0033] Among them, the UV protection layer 9 is made of polyester. Polyester has good UV absorption properties, which can effectively block harmful UV rays. In addition, polyester material has strong weather resistance and can maintain stability for a long time under different climatic conditions.

[0034] The working principle of this embodiment is as follows: During storage and transportation, the protective film 2 can protect the sheet body 1, the moisture-proof layer 8 reduces moisture penetration, and the UV-resistant layer 9 reduces UV penetration, thereby reducing damage to the sheet body 1. When using the PP sheet, the staff can peel off the protective film 2. The reinforcing layer 4 set inside the sheet body 1 can increase the strength and toughness of the sheet body 1, the flame-retardant layer 5 can reduce the spread of flame when the sheet is burning, and the semi-conductive layer 6 can reduce the accumulation of static electricity on the surface of the sheet body 1.

[0035] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
