[0019] Specifically, the adhesive layer 2 is made of organic silicon adhesive to ensure the bonding effect of the fireproof bandage, the insulating layer 3 is made of PVC material to improve the insulation performance of the fireproof bandage, and the waterproof layer 4 is made of polytetrafluoroethylene to increase the waterproof effect of the fireproof bandage.

[0020] Specifically, the first fireproof layer 5 and the second fireproof layer 7 are formed by twisting mica fibers. The surfaces of the first fireproof layer 5 and the second fireproof layer 7 are sprayed with high-temperature resistant coatings. The surfaces of the armor layer 8 and the buffer ring 9 are also sprayed with high-temperature resistant coatings. Fluorocarbon paint can be used for the high-temperature resistant coating. The fireproof performance of the fireproof bandage is guaranteed by the setting of the first fireproof layer 5 and the second fireproof layer 7 in conjunction with the high-temperature resistant coating.

[0021] Specifically, the reinforcing layer 6 is a stainless steel mesh layer, and the reinforcing layer 6 is formed by interlacing and weaving stainless steel wires to improve the structural strength of the fireproof bandage and improve the tensile strength and bending resistance.

[0022] Specifically, the reinforcing ribs 10 are elastic metal strips, each of which penetrates the base layer 1 along the width direction of the base layer 1, and a plurality of reinforcing ribs 10 are evenly arranged along the length direction of the base layer 1 to improve the bending resistance of the fireproof bandage.
