Although various aspects of the embodiments are illustrated in the drawings, the drawings are not necessarily drawn to scale unless specifically indicated.

[0022] The word "exemplary" is used herein to mean "serving as an example, instance, or illustration." Any implementation described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other implementations.

[0023] In addition, for the purpose of convenience and brevity, specific details of various embodiments are set forth in the following description. It should be appreciated that the application can be practiced without some or all of the specific details set forth in the following description. In some instances, well known structures, materials, or methods have not been described in detail in order to avoid obscuring the application.

[0024] Reference Figures 1-6 The utility model provides 2 kinds of technical schemes:

[0025] Embodiment one:

[0026] A heat insulation and flame-retardant waterproof board, including plate body 1, the outer wall of plate body 1 is fixedly connected with the protective layer 101 that provides strength, the inner wall of protective layer 101 is fixedly connected with multiple supporting bumps 102, plate body 1 inside is provided with cooling layer 2 for heat insulation and flame-retardant;

[0027] Cooling layer 2 includes the cooling plate 201 of setting in the center of plate body 1, and the inside of cooling plate 201 is hollow, is provided with multiple notches 202 on cooling plate 201, and the inner side wall one end of notch 202 is fixedly connected with the deformation plate 203 that bends to one side when meeting high temperature, and the other end of deformation plate 203 is in abutment with the inner wall of notch 202, and the inner side wall of deformation plate 203 is fixedly connected with the sealing strip 204 for sealing notch 202, and the bottom of cooling plate 201 is fixedly connected with multiple heat conduction columns 205.

[0028] Plate body 1 is fixedly connected with heat insulation layer 3 on the outer wall of cooling layer 2, and heat insulation pipe 301 is arranged in heat insulation layer 3, and heat conduction seat 302 is fixedly connected to the outer wall of heat insulation pipe 301, and plastic film that melts when meeting high temperature is fixedly sleeved to the end of heat insulation pipe 301.

[0029] Specifically, when the high temperature is first conducted to the heat insulation layer 3, since the heat insulation layer 3 is fixedly connected to the heat insulation tube 301 through the heat conduction seat 302, and the heat insulation tube 301 is filled with water, and plastic films that melt when encountering high temperature are set at the ends of the pipe mouth, the plastic film can ensure that the water in the heat insulation tube 301 will not leak, and the heat insulation layer 3 is filled with ammonium nitrate powder. Therefore, when the high temperature is transmitted to the heat insulation tube 301 through the heat conduction seat 302, the plastic films at both ends of the heat insulation tube 301 are melted when subjected to high temperature conduction. When the water in the heat insulation tube 301 flows out, it contacts with the ammonium nitrate powder and absorbs a large amount of heat for reaction, which can quickly absorb the heat conducted from the outside, and the structure of this layer is small and does not affect the waterproof performance of the waterproof board itself. When the remaining heat is conducted to the cooling plate 201, the interior of the cooling plate 201 is hollow and filled with cooling oil for cooling, and Since there are multiple heat-conducting columns 205 fixedly connected to its bottom, and the heat-conducting columns 205 have better heat conductivity than the cooling plate 201, when high temperature comes, the heat-conducting columns 205 will first absorb part of the heat and transfer it to the cooling oil. The cooling oil's own material properties can first dissipate the remaining heat through the heat-conducting columns 205. When the heat is too high, since there are multiple slots 202 on its outer wall, and a deformable plate 203 is fixedly connected to one side of the slot 202, the deformable plate 203 is composed of two metals with different thermal expansion and contraction properties, and the layer close to the cooling plate 201 is higher than the outer layer. Therefore, when the temperature is high, it will bend outward, so the slot 202 is opened to allow the cooling oil in the cooling plate 201 to flow into the thermal insulation layer 3. This layer can ensure the integrity of the waterproof board, and can release a large amount of heat through the multi-layer thermal insulation and flame retardancy of the outer layer. When this layer does not react, it does not affect the daily use of the waterproof board.

[0030] Example 2:

[0031] Based on Example 1:

[0032] A highly flame-retardant polyolefin layer 4 is provided on the outer wall of the heat-insulating layer 3 of the plate body 1 , and distributed oblique blocks 401 are provided inside the highly flame-retardant polyolefin layer 4 .

[0033] The plate body 1 is provided with a vacuum layer 5 on the outer wall of the highly flame-retardant polyolefin layer 4. The outer wall of the vacuum layer 5 is coated with a flame retardant and the interior thereof is filled with an inert gas.

[0034] An oil inlet 206 for filling cooling oil is fixedly connected to the side wall of the cooling plate 201 , and a plug 207 is movably connected to the inner wall of the oil inlet 206 .

[0035] Specifically, by connecting the rigid layer 6 with the protective layer 101, the stiffness of the waterproof board can be ensured, and the waterproof board has sufficient plasticity so as not to be damaged by collision during use. The vacuum layer 5 can improve the heat insulation and flame resistance of the waterproof board. The vacuum layer 5 can avoid heat transfer, and there are almost no air molecules in the vacuum layer 5, which can avoid air as a combustion-supporting source. The flame retardant coated on the outer wall of the vacuum layer 5 can reduce the possibility of combustion caused by heat, and then the heat is conducted to the high-flame-retardant polyolefin layer 4. The layer can prevent the possibility of combustion by its material properties, and when the heat is too high, the layer will generate a carbon layer after burning. The carbon layer after burning can absorb part of the heat while consuming oxygen entering the board body 1, and can also avoid the continuous conduction of heat. The ceramicized silicone rubber filled in the board body 1 can be converted into a hard ceramic body after burning, which has the characteristics of fireproofing and flame resistance. The multiple heat insulation and flame resistance layers arranged on the outer wall of the board body 1 can ensure that the combustion efficiency is reduced at high temperatures, and the damage effect of external temperature on the waterproof board body is reduced, greatly improving the use efficiency and service life of the waterproof board.

[0036] Working principle: when the combustion caused by high temperature meets the board body 1 of the waterproof board, the protective layer 101 on the outermost layer of the board body 1 will first resist the high temperature, and then the heat is transferred to the vacuum layer 5. Since the vacuum layer 5 is hollow, the speed of heat transfer can be slowed down, and the effect of flame resistance can be improved. The high-flame-retardant polyolefin layer 4 that can be carbonized by high-temperature combustion can absorb heat by carbonization while avoiding the possibility of heat continuing to transmit inward to cause combustion. Then, the heat insulation pipe 301 and the water body in it and the ammonium nitrate powder filled in the heat insulation layer 3 react to quickly absorb a large amount of heat, further improving the flame resistance effect. The cooling oil filled in the cooling layer 2 can ensure that the board body 1 of the waterproof board is not damaged by high temperature under the condition of external high temperature. The structure is simple and practical, and does not affect the use of the waterproof board while ensuring its heat insulation and flame resistance.
