DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1 and Figure 5 A high-strength, flame-retardant composite rubber sheet includes a web layer 10 and four rubber layers 20. The four rubber layers 20 are symmetrically positioned on the outside of the web layer 10, and are bonded and fixed to each other using an adhesive. The four rubber layers 20 embed the web layer 10 between the four rubber layers 20 to form a composite structure.

[0022] See Figure 2 and Figure 3 The mesh layer 10 includes an upper plate layer 11, a middle plate layer 12 and a lower plate layer 13. The upper plate layer 11, the middle plate layer 12 and the lower plate layer 13 are all configured as steel plate structures, the middle plate layer 12 is disposed between the upper plate layer 11 and the lower plate layer 13, and the upper plate layer 11, the middle plate layer 12 and the lower plate layer 13 are welded and fixed to form an integral structure. The upper plate layer 11 and the lower plate layer 13 can be pre-symmetrically formed with a plurality of evenly distributed upper plate grooves 111 and lower plate grooves 131 by laser cutting. In addition, a plurality of hollow grooves 14 penetrating the mesh layer 10 are also formed on the mesh layer 10. The hollow grooves 14 are respectively connected to adjacent upper plate grooves 111 and lower plate grooves 131. The multi-layer structure of the mesh layer 10 and the arrangement of grooves at different positions can improve the shear and tear resistance of the mesh layer. There are gaps between the outer edge of the middle plate layer 12 and the outer edges of the upper plate layer 11 and the lower plate layer 13 , and the gaps are used to facilitate the assembly of the rubber layer 20 .

[0023] See Figure 4 The rubber layer 20 includes a facing rubber layer 21, an edge rubber layer 22, and an inner fold layer 23. The edge rubber layer 22 is formed at the outer edge of the facing rubber layer 21, and the inner fold layer 23 is formed at the outer edge of the edge rubber layer 22. A positioning groove 24 with an opening is formed between the facing rubber layer 21, the edge rubber layer 22, and the inner fold layer 23. The thickness of the positioning groove 24 is set to half the height of the gap between the middle plate layer 12 and the upper plate layer 11 and the lower plate layer 13. By cooperating with the positioning groove 24 and the mesh layer 10, the rubber layer 20 can be inserted into the gap between the middle plate layer 12 and the upper plate layer 11 and the lower plate layer 13, and the four rubber layers 20 can wrap the mesh layer 10 after assembly. The rubber layer 20 as a whole can be made of chloroprene rubber, chlorosulfonated polyethylene rubber, or silicone rubber to make it have a better flame retardant effect.
