[0020] Some embodiments of the present patent will be described in detail below with reference to the accompanying drawings. The features in the following examples can be combined with each other without conflict.

[0021] Example One:

[0022] As shown in Figures 1 to 4 The high-pressure-resistant impact-resistant PVC composite board comprises a pressure-bearing layer 10 and a buffer layer 20 installed on the pressure-bearing layer 10. The pressure-bearing layer 10 comprises a plurality of porous plates one 11 and a plurality of porous plates two 12. The porous plates one 11 and the porous plates two 12 are arranged at intervals, and the hole positions on the porous plates one 11 and the porous plates two 12 are staggered with each other to form a honeycomb structure. The buffer layer 20 comprises an upper base plate 21 and a lower base plate 22. A pair of mirror-image wave plates 23 are arranged between the upper base plate 21 and the lower base plate 22. A buffer 24 is arranged between the troughs of the two wave plates 23.

[0023] The high-pressure-resistant impact-resistant PVC composite board is composed of the pressure-bearing layer 10 and the buffer layer 20. The pressure-bearing layer 10 has good pressure-bearing capacity, so the pressure-bearing layer 10 is composed of a plurality of porous plates one 11 and a plurality of porous plates two 12 arranged at intervals. The number of the porous plates one 11 and the porous plates two 12 can be determined according to actual conditions. The hole positions on the porous plates one 11 and the porous plates two 12 are staggered with each other to form a honeycomb structure (as shown in Figure 3), the honeycomb structure is arranged by a plurality of hole dislocations, the geometric shape optimizes the load transmission path, has high compression and bending strength, and furthermore, the honeycomb structure has good energy absorption effect and good impact resistance.

[0024] In order to increase the impact force of the PVC plate, the buffer layer 20 is added on the basis of the pressure bearing layer 10; the impact resistance effect is realized by arranging a pair of mirror image wave plates 23 between the upper substrate 21 and the lower substrate 22; the two wave plates 23 are mirror arranged, and the wave crest is in contact with the wave crest (as Figure 4 ), when impacted, elastic bending occurs at the wave crest, stress gradient is generated inside, impact kinetic energy is converted into elastic strain energy storage, and when bending resets, strain energy is partially converted into heat energy dissipation, so as to realize the impact resistance effect; and the design of wave crest and wave crest contact can make the two wave plates 23 more easily convert impact kinetic energy into elastic strain energy when bending.

[0025] In the existing design, in order to realize the impact resistance, springs are added between the plates, although the impact kinetic energy can be converted into elastic strain energy, but the springs are easy to rust and damage, which greatly reduces the service life of the PVC composite plate, therefore, in order to provide the buffering capacity of the PVC composite plate, the buffer 24 is arranged between the wave troughs of the two wave plates 23; when the wave crests of the two wave plates 23 are bent and deformed, the stress is transmitted to the buffer 24 through the wave trough, and the buffer 24 is further consumed.

[0026] As Figure 5 shown, the buffer 24 is made of rubber material, including a pair of bases 241, a connecting plate 242 arranged between the pair of bases 241, T-shaped heads 243 arranged at both ends of the connecting plate 242, and limiting strips 245 arranged on both sides of the T-shaped heads 243; the base 241 is provided with a T-shaped groove 244 and a limiting groove 246 arranged in the T-shaped groove 244; the connecting plate 242 is connected with the base 241 by inserting the T-shaped head 243 into the T-shaped groove 244; the limiting strip 245 is arranged in the limiting groove 246.

[0027] The stress of the crest deformation of the two wave plates 23 is transmitted to the two bases 241 through the trough, and the connecting plate 242 arranged between the two bases 241 is extruded by the two bases 241; the T-shaped head 243 at both ends of the connecting plate 242 is inserted into the T-shaped groove 244 of the base 241, and the T-shaped head 243 is extruded and rebounded in the T-shaped groove 244 due to the T-shaped structure of the T-shaped head 243, so that the stress is transmitted to the connecting plate 242, the connecting plate 242 is deformed and bent, and the buffering effect is achieved; in the process, in order to prevent the connecting plate 242 from being popped out of the T-shaped groove 244 when being deformed, a limiting strip 245 is arranged on the T-shaped head 243, and the limiting strip 245 is clamped in the limiting groove 246.

[0028] The basic principle and main features of the utility model and the advantages of the utility model are shown and described above, and it is obvious for those skilled in the art that the utility model is not limited to the details of the above exemplary embodiments, and the utility model can be realized in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-limiting, the scope of the utility model is defined by the appended claims instead of the above description, and therefore all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the utility model. Any figure reference in the claims should not be regarded as limiting the involved claims.
