[0011] Advantages of the present utility model: By providing the wear-resistant layer, the toughness layer and the flying wires, when the protective film is attached to the surface of an object, the wear-resistant layer serves as the base material of the protective film, enabling the protective film body to have good wear-resistant and anti-drop performance. The toughness layer is wrapped inside the wear-resistant layer, which can enhance the toughness of the protective film body while maintaining the wear-resistant performance. At the same time, two sets of flying wires are provided to pull and contract the protective film body from the inside, acting as a reinforcing rib. Moreover, the high-tough resin material has very good advantages of bendability, stretchability and fatigue resistance, which can further improve the toughness of the protective film body.

[0018] The technical solutions of the present utility model will be further described below in conjunction with the drawings and through specific embodiments.

[0019] Among them, the drawings are only for illustrative purposes, showing only schematic diagrams, not physical diagrams, and should not be construed as a limitation to this patent; in order to better illustrate the embodiments of the present utility model, some components in the drawings will be omitted, enlarged or reduced, which do not represent the dimensions of the actual product; for those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted.

[0020] Refer to Figures 1 to 3The high-toughness protective film shown, the protective film body, the protective film body includes a wear-resistant layer 1, a toughness layer 10 and two groups of flying wires 11. The wear-resistant layer 1 wraps around the periphery of the toughness layer 10. By using the wear-resistant layer 1 as the base material of the protective film, the protective film body has good wear-resistant and anti-drop performance. The toughness layer 10 is wrapped inside the wear-resistant layer 1, which can improve the toughness of the protective film body while maintaining the wear-resistant performance. A cavity 100 is provided inside the toughness layer 10. The flying wires 11 are fixedly arranged in the cavity 100 and fixedly connected to the toughness layer 10. The two groups of flying wires 11 are symmetrically arranged, and the material of the flying wires 11 is a high-tough resin material. By setting the two groups of flying wires 11 to pull and contract the protective film body from the inside, it plays the role of a reinforcing rib, and the high-tough resin material has the advantages of very good bendable, stretchable and fatigue-resistant properties, further improving the toughness of the protective film body.

[0021] The two groups of flying wires 11 are arranged to cross each other, and both ends and corners of the flying wires 11 are wrapped in the toughness layer 10. By arranging the two groups of flying wires 11 symmetrically and crosswise, the two sides of the protective film are evenly stressed, and part of the flying wires 11 is wrapped in the toughness layer 10, making its connection with the toughness layer 10 closer.

[0022] The material of the wear-resistant layer 1 is polyethylene terephthalate. Polyethylene terephthalate material has excellent wear resistance, electrical insulation, flame retardancy, heat aging resistance and low water absorption and other characteristics, which can well ensure the wear-resistant and anti-drop performance of the protective film, and at the same time improve the insulation, flame retardancy and waterproof performance of the protective film. The material of the toughness layer 10 is high-density polyvinyl chloride. High-density polyvinyl chloride material has good impact resistance and tensile resistance. As the toughness layer 10 of the protective film, when the protective film is bent and deformed, it can rebound and prevent it from breaking.

[0023] It also includes an adhesive layer 12. The top of the adhesive layer 12 is fixedly connected to the bottom of the wear-resistant layer 1. The material of the adhesive layer 12 is acrylic glue. Acrylic glue is commonly known as pressure-sensitive adhesive, which has good stability, excellent peelability, strong cohesive force in the adhesive film, high transparency, does not delaminate, and is not easy to remain on the base material. When using the protective film, the adhesive layer 12 is attached to the surface of the position where the film needs to be pasted, and the protective film can be stably pasted at the designated position through the acrylic glue.

[0024] It also includes a film layer 13. The film layer 13 is attached to the bottom of the adhesive layer 12 and the periphery of the wear-resistant layer 1. One end of the film layer 13 is fixedly connected with a tab 14. Through the film layer 13, during the transfer and storage of the protective film, it is protected to prevent dust and the like from contaminating it. The film layer 13 is made of anti-adhesive paper. Using the easy-to-peel characteristic of the anti-adhesive paper and cooperating with the tab 14 at one end of it, it can be easily torn off, so as to paste the protective film in the appropriate position.

[0025] It should be noted that the above specific embodiments are only the preferred embodiments of the present utility model and the applied technical principles. Those skilled in the art should understand that various modifications, equivalent substitutions, changes, etc. can also be made to the present utility model. However, as long as these transformations do not deviate from the spirit of the present utility model, they should be within the protection scope of the present utility model. In addition, some terms used in the description and claims of this application are not restrictive, but are only for the convenience of description.
