[0026] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model; it is obvious that the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the utility model without making creative work are within the scope of protection of the utility model.

[0027] Example:

[0028] See also Figure 1-6 A PVC fireproof board comprises a PVC base layer 1, a moisture-proof layer 2 is arranged on the top and bottom of the PVC base layer 1, a fireproof layer 3 is arranged on the side of the moisture-proof layer 2 away from the PVC base layer 1, a protective outer layer 4 is arranged on the outer side of the fireproof layer 3, and a supporting component is arranged inside the protective outer layer 4;

[0029] The support assembly includes a vertical buffer column 6, and vertical connecting columns 7 are arranged at the top and bottom of the vertical buffer column 6. A vertical connecting column 7 is fixed to the side of the vertical connecting column 7 away from the vertical buffer column 6. The vertical connecting column 7 is fixedly connected to the protective outer layer 4. When the protective outer layer 4 is impacted, the circular sliding sheet 8 can move inside the vertical buffer column 6 through the vertical connecting column 7, thereby supporting the PVC base layer 1, the moisture-proof layer 2 and the fireproof layer 3.

[0030] Circular through holes are provided inside the moisture-proof layer 2 and the fire-proof layer 3. The vertical connecting column 7 is located inside the circular through holes and is slidably connected to the moisture-proof layer 2 and the fire-proof layer 3 through the circular through holes. The vertical connecting column 7 can slide inside the moisture-proof layer 2 and the fire-proof layer 3 through the setting of the circular through holes. The vertical buffer column 6 is located inside the PVC base layer 1 and is fixedly connected to the PVC base layer 1.

[0031] The material of the vertical buffer column 6 is rubber. Due to the material characteristics of the vertical buffer column 6, when the circular sliding sheet 8 moves, the vertical buffer column 6 is deformed, thereby providing shock-absorbing and buffering performance for the plate.

[0032] The top and bottom of the protective outer layer 4 are both provided with a wear-resistant layer 5, which is a stainless steel plate. The material characteristics of the wear-resistant layer 5 can provide the plate with wear resistance to prevent damage to the plate due to scratches;

[0033] The material of the moisture-proof layer 2 is polypropylene, which has a low water absorption rate. Therefore, it can maintain stable performance in a humid environment, is not easily deformed by moisture, has high wear resistance and chemical resistance, can resist the erosion of most acids and alkalis, and has a long service life. The material of the fireproof layer 3 is chlorinated polyethylene, which has good flame retardant properties, can effectively slow down the spread of fire, and reduce the occurrence and expansion of fire accidents.

[0034] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
