Description

Technical Field

[0001] The utility model relates to the technical field of films, in particular to a film with strong tensile strength. Background Art

[0002] Film is a thin and soft sheet made of plastic, adhesive, rubber or other materials. The scientific explanation of film is: a two-dimensional material formed by the deposition of atoms, molecules or ions on the surface of a substrate. Examples include optical films, composite films, superconducting films, polyester films, nylon films, plastic films, etc. Films are widely used in electronics, machinery, printing and other industries. Film materials refer to thin metal or organic layers with a thickness ranging from a single atom to several millimeters. Electronic semiconductor functional devices and optical coatings are the main applications of thin film technology.

[0003] Please refer to the patent for a film with strong tensile strength with announcement number CN215921437U, which states that "the existing film is easily damaged due to stretching, which affects the use of the film, especially when the film is subjected to the force of other hard objects, the film is easily damaged"; the above patent provides a fiber layer between the two layers of film, and the fiber layer is used to strengthen the tensile strength of the film. When the film is subjected to external forces such as pulling force, the fiber filaments in the film can share the force exerted on the film, thereby enhancing the tensile strength of the film. At the same time, the provided base layer can further enhance the tensile strength of the film.

[0004] However, although the fiber layer provided in the above patent can improve the tensile properties of the film, its structure is relatively simple. After repeated pulling, the structure of the fiber layer is easily destroyed, causing the film to be damaged due to the weakening of the tensile properties, and its practical effect is poor. In view of this, the present application proposes a film with strong tensile resistance. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a film with strong tensile resistance, which has the advantages of enhancing the tensile resistance of the film while improving the film's resistance to tensile force, thereby preventing the film from being damaged due to excessive tensile force. In addition, a protective structure can be used to prevent the film from being damaged by foreign objects, thereby effectively improving the practicality of the device, etc., solving the problem that the existing film is easily damaged by stretching, thereby affecting the use of the film, especially when the film is subjected to the force of other hard objects, the film is easily damaged.

[0006] To achieve the above object, the utility model provides the following technical solution: a film with strong tensile strength, comprising two polyester film base layers, wherein the inner and outer sides of the polyester film base layers are respectively provided with a tensile structure and a protective structure;

[0007] The tensile structure includes polyester resin, nylon braided layer, metal fiber layer, flexible plate and elastic block arranged on the opposite side of the two polyester film base layers; the protective structure includes an anti-scratch layer and a wear-resistant layer arranged on the separated side of the two polyester film base layers.

[0008] Furthermore, the flexible plate is wavy in shape, and a plurality of elastic blocks are fixedly connected in the recess of the flexible plate.

[0009] Furthermore, the flexible plate is arranged in the metal fiber layer, and the number of the nylon braided layer and the number of the metal fiber layer are both two.

[0010] Furthermore, a polyester resin is fixedly connected to a side of the polyester film base layer close to the metal fiber layer, and a nylon braided layer fixedly connected to the metal fiber layer is provided on a side of the polyester resin close to the metal fiber layer.

[0011] Furthermore, a scratch-resistant layer is fixedly connected to one side of the two polyester film base layers that are separated from each other, and a wear-resistant layer is fixedly connected to one side of the scratch-resistant layer that is away from the polyester film base layer.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0013] The film with strong tensile strength can share the force exerted on the film when the film is subjected to external forces such as pulling force, thereby enhancing the tensile strength of the film, and the cooperation of the flexible plate and elastic block can effectively improve the film's ability to resist tensile force, so as to further enhance the tensile strength of the film while preventing the film from being damaged by excessive tensile force.
