[0020] The present invention is described in detail below in conjunction with specific embodiments.
[0021] In the present utility model, unless otherwise clearly specified and limited, when terms such as "set on", "connected", and "connected" appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or connected through one or more intermediate media. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances. The directional words that appear in the present utility model are to better illustrate the characteristics of the features and the relationship between the features. It should be understood that when the placement direction of the present utility model changes, the characteristics of the features and the direction of the relationship between the features also change accordingly. Therefore, the directional words do not constitute an absolute limitation on the characteristics of the features and the relationship between the features in space, but only play a relative limitation role.
[0022] The utility model provides a lightweight steel plate reinforcement film, such as Figures 1 to 3 As shown, it includes a paper release layer 1, an adhesive layer 2 and a reinforcing layer 3 stacked in sequence from bottom to top; the reinforcing layer 3 includes a reinforcing rubber layer 31, a lower reinforcing mesh layer 32 and an upper reinforcing mesh layer 33, the reinforcing rubber layer 31 is connected to the upper surface of the lower reinforcing mesh layer 32 and to the lower surface of the upper reinforcing mesh layer 33, and the lower reinforcing mesh layer 32 is connected to the upper surface of the adhesive layer 2; the reinforcing rubber layer 31 is a honeycomb structure, and the lower reinforcing mesh layer 32 and the upper reinforcing mesh layer 33 are both grid structures.
[0023] Based on the above structural setting, the reinforcing rubber layer 31 is a honeycomb structure, which can provide excellent compression and bending resistance while reducing the use of materials, thereby reducing the overall weight; and the lower reinforcing mesh layer 32 and the upper reinforcing mesh layer 33 are both grid structures, which further improve the strength and stability of the overall structure; therefore, through the design of the reinforcing layer 3, the steel plate reinforcing rubber sheet can achieve maximum lightweight while maintaining the reinforcement effect.
[0024] In this embodiment, the reinforcing adhesive layer 31 is provided with a plurality of hexagonal cavity units 311. The provision of the hexagonal cavity units 311 removes excess material while maintaining sufficient strength and stability, thereby achieving lightweight structure.
[0025] In this embodiment, the lower reinforcing mesh layer 32 and the upper reinforcing mesh layer 33 are both provided with a plurality of transverse reinforcing ribs 321, upper oblique reinforcing ribs 322 and lower oblique reinforcing ribs 323; the transverse reinforcing ribs 321, the upper oblique reinforcing ribs 322 and the lower oblique reinforcing ribs 323 respectively connect the three groups of diagonal angles of the hexagonal cavity unit 311 and intersect inside the hexagonal cavity unit 311. Through the above structural design, the structural stability of the hexagonal cavity unit 311 can be effectively enhanced, and it can withstand forces and torques from different directions, thereby improving the deformation resistance of the overall structure.
[0026] In this embodiment, the upper surface of the upper reinforcing mesh layer 33 is connected with a damping layer 4, and the damping layer 4 covers the reinforcing layer 3 and is connected to the upper surface of the lower reinforcing mesh layer 32.

Through the structural design above, the damping layer 4 is more firmly fixed, and the transmission of vibration to other structural layers is reduced, which helps the damping layer 4 to better exert its vibration reduction effect.
[0028] In this embodiment, the upper surface of the damping layer 4 is connected with a wear-resistant layer 5, which can resist wear and friction and increase the service life of the steel plate reinforcing film.
[0029] In this embodiment, the adhesive layer 2 is made of epoxy resin, which can achieve excellent adhesion and durability.
[0030] In this embodiment, the reinforcing rubber layer 31, the lower reinforcing mesh layer 32 and the upper reinforcing mesh layer 33 are all made of glass fiber, which can improve the overall strength and rigidity of the steel plate reinforcing rubber sheet.
[0031] In this embodiment, the thickness of the lower reinforcing mesh layer 32 is equal to the thickness of the upper reinforcing mesh layer 33, which can provide balanced support for the reinforcing rubber layer 31, thereby improving the overall stability and reliability of the structure, reducing the types of raw materials required for manufacturing the product, and reducing production costs.
