The internal structure layer 2 is a single-layer structure, and both the intermediate heat insulation layer 3 and the external wear-resistant layer 4 are double-layer structures. The double-layer intermediate heat insulation layer 3 takes the internal structure layer 2 as the symmetry center and is arranged closely against the upper and lower end faces of the internal structure layer 2. The double-layer external wear-resistant layer 4 is respectively arranged on the upper and lower end faces of the double-layer intermediate heat insulation layer 3. The material of the internal structure layer 2 is polycarbonate polymer, and the material of the intermediate heat insulation layer 3 is asbestos. Taking the internal structure layer 2 as the symmetry center, the double-layer intermediate heat insulation layer 3 is arranged closely against the upper and lower end faces of the internal structure layer 2.
