[0002] Rubber sheet, also known as rubber sheet, is a thick, large-area sheet made primarily of rubber through vulcanization. Rubber sheet is formed by calendering, laminating, or extruding a rubber mix, followed by vulcanization using a flat plate vulcanizer or continuous vulcanization using a drum vulcanizer. As a subcategory of rubber sheet, insulating rubber sheet offers superior insulation compared to standard rubber sheet and is widely used in industrial and mining enterprises, transportation, and flooring applications.

DETAILED DESCRIPTION

[0023] 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.

[0024] See also Figure 1 and Figure 2 An aging-resistant insulating rubber sheet comprises a top rubber layer 10, a bottom rubber layer 20, a steel mesh layer 30, and a covering layer 40. The facing sides of the top rubber layer 10 and the bottom rubber layer 20 are in contact with each other, and the top rubber layer 10 and the bottom rubber layer 20 are bonded and fixed together using an adhesive layer 50. Alternatively, the bonding surfaces of the top rubber layer 10 and the bottom rubber layer 20 may be pre-coated with an adhesive for bonding. The steel mesh layer 30 may be pre-embedded between the top rubber layer 10 and the bottom rubber layer 20, and the steel mesh layer 30 may be clamped inside by bonding between the top rubber layer 10 and the bottom rubber layer 20. The covering layer 40 may be made of butyl rubber, which exhibits excellent resistance to aging, ozone, and chemicals. The top rubber layer 10 and the bottom rubber layer 20 may be made of EPDM, which exhibits excellent weather resistance, heat resistance, and ozone resistance, making it suitable for use as an insulating rubber sheet outdoors and in high-temperature environments.

[0025] See Figures 2 to 4The top rubber layer 10 has a first groove 11 formed on its lower surface, which mates with the steel mesh layer 30. The bottom rubber layer 20 has a second groove 21 formed on its upper surface, which mates with the steel mesh layer 30. The steel mesh layer 30 is formed by a plurality of crisscrossing steel bars, forming a grid-like, integrated structure. This allows the steel mesh layer 30 to be embedded between the top and bottom rubber layers 10, 20, thereby reinforcing the entire rubber sheet. Furthermore, the top rubber layer 10 has a first frame 12 formed on its lower surface, located outside the first groove 11. An annular positioning groove 13 is formed between the first groove 11 and the first frame 12. The bottom rubber layer 20 has a second frame 22 formed on its upper surface, located outside the second groove 21. A positioning bar 23 protrudes between the second groove 21 and the second frame 22, mates with the positioning groove 13. This allows the positioning bar 23 to mate with the positioning groove 13 when the top and bottom rubber layers 10 and 20 are assembled. There is a gap between the first frame 12 and the outer edge of the top rubber layer 10, and there is a gap between the second frame 22 and the outer edge of the bottom rubber layer 20. During assembly, adhesive can be applied to the facing surfaces of the top rubber layer 10 and the bottom rubber layer 20, and adhesive can be filled in the gap between the top rubber layer 10 and the first frame 12, as well as in the gap between the bottom rubber layer 20 and the second frame 22. The adhesive filled in the gap between the top rubber layer 10 and the first frame 12, as well as in the gap between the bottom rubber layer 20 and the second frame 22, forms an adhesive layer 50 after solidification.

[0026] See Figure 5 and Figure 6 A flow channel 41 is formed on the top of the covering layer 40. The flow channel 41 is composed of a plurality of crisscrossing rectangular grooves. A plurality of connecting grooves 43 are also formed at the outer edge of the covering layer 40. The connecting grooves 43 are arranged in a semicircular arc shape with a diameter greater than the width of the rectangular grooves in the flow channel 41, and each connecting groove 43 is connected to the end of the adjacent rectangular groove in the flow channel 41, so that when the anti-aging insulating rubber sheets are laid in combination, the tops of multiple anti-aging insulating rubber sheets can be connected to form a flow channel for draining liquid. The depth of the flow channel 41 is less than the thickness of the covering layer 40, and the depth of the connecting grooves 43 is equal to the thickness of the covering layer 40. When multiple anti-aging insulating rubber sheets are laid in combination, fixing nails can be nailed into the connecting grooves 43 to connect and fix the adjacent anti-aging insulating rubber sheets, and the tops of the fixing nails can be flush with the inner bottom wall of the flow channel 41. In addition, the flow channel 41 can divide the top of the covering layer 40 into a plurality of anti-slip protrusions 42, so that when the anti-aging insulating rubber sheet is used as a floor, the risk of people slipping on its surface can be reduced.

[0027] In all the schemes mentioned above, the connection between the two components can be selected according to actual conditions by welding, bolt and nut connection, bolt or screw connection or other well-known connection methods, which will not be listed here one by one. In the above, all fixed connections are preferably welded. Although the embodiments of the present invention have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the attached claims and their equivalents.
