Description

Technical Field

[0001] This utility model relates to the field of composite board technology, and in particular to PVC composite boards with excellent sound insulation effect. Background Technology

[0002] PVC composite board refers to flooring made from polyvinyl chloride. Specifically, it is made from polyvinyl chloride and its copolymer resin as the main raw materials, with the addition of fillers, plasticizers, stabilizers, colorants and other auxiliary materials, and is produced on a continuous sheet substrate through coating, calendering, extrusion or compression processes.

[0003] While existing PVC composite panels have advantages such as low cost, good performance, moisture resistance, environmental friendliness, non-toxicity, and wide range of applications, their sound insulation effect is poor compared to walls. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a PVC composite board with excellent sound insulation effect. The PVC composite board is designed with a sound insulation structure and has a good sound insulation effect.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A PVC composite board with excellent sound insulation properties includes: a surface layer, a sound-absorbing layer disposed on the surface layer, a cavity layer disposed on the sound-absorbing layer, and a backing layer disposed on the cavity layer.

[0007] Preferably, the surface layer comprises an ABS sheet with sound-guiding holes formed in the ABS sheet.

[0008] Preferably, the sound-absorbing layer is composed of multiple sound-absorbing panels stacked one on top of the other.

[0009] Preferably, the sound-absorbing layer is formed by stacking two sound-absorbing panels one on top of the other; the sound-absorbing panel includes a fiberboard, sound-absorbing holes formed on the fiberboard, and sound holes perpendicularly penetrating the sound-absorbing holes; the two sound-absorbing panels are stacked by aligning the centers of their respective sound holes.

[0010] Preferably, the silencing hole is an isosceles trapezoidal structure, and the sound wave enters the silencing hole through the sound hole on the short base side and exits through the sound hole on the long base side.

[0011] Preferably, the cavity layer is composed of multiple porous plates stacked together.

[0012] Preferably, the cavity layer is composed of three perforated plates stacked together, and the holes of the three perforated plates are staggered to form a honeycomb structure.

[0013] Preferably, the backing layer is a rubber damping plate.

[0014] Compared with the prior art, this application has the following beneficial effects:

[0015] This invention effectively achieves sound insulation through the combined action of three sound-absorbing structures: a sound-absorbing layer, a cavity layer, and a backing plate layer. Specifically, the sound-absorbing layer consists of multiple sound-absorbing plates, each with sound-absorbing holes in an isosceles trapezoidal shape. The overlapping of these sound-absorbing plates creates a muffler structure. The cavity layer also comprises multiple perforated plates stacked together, with staggered holes forming a honeycomb structure, which provides excellent sound insulation. Finally, the backing plate layer uses a rubber damping plate, which is elastic, rebounds sound waves, and also has a sound-absorbing effect. The combined effect of these three structures creates a comprehensive sound insulation structure, effectively achieving sound insulation. Attached Figure Description

[0024] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the features in the following embodiments can be combined with each other.

[0025] Example 1:

[0026] like Figure 1 As shown, the PVC composite board with excellent sound insulation effect includes: a surface layer 10, a sound-absorbing layer 20 disposed on the surface layer 10, a cavity layer 30 disposed on the sound-absorbing layer 20, and a back panel layer 40 disposed on the cavity layer 30; the sound-absorbing layer 20 is composed of multiple sound-absorbing panels 21 stacked on top of each other; the cavity layer 30 is composed of multiple perforated panels 31 stacked on top of each other.

[0027] This embodiment mainly achieves sound absorption and sound insulation through the structure of sound-absorbing layer 20 and cavity layer 30. When there is noise, the sound wave enters the sound-absorbing layer 20 from the surface layer 10. After the first stage of noise reduction, the noise-reduced sound wave enters the cavity layer 30 for the second stage of noise reduction, thus achieving the sound insulation effect.

[0028] In order to make the sound-absorbing layer 20 and the cavity layer 30 have good sound insulation effect, the sound-absorbing layer 20 adopts two sound-absorbing plates 21, and the cavity layer 30 adopts three perforated plates 31; the number of sound-absorbing plates 21 and perforated plates 31 can be designed according to the actual situation, and this embodiment does not limit it.

[0029] The sound waves are weakened multiple times as they pass through the two sound-absorbing plates 21 and the three perforated plates 31, effectively reducing noise.

[0030] like Figure 2 As shown, the surface layer 10 includes an ABS plate 11 and sound-guiding holes 12 formed on the ABS plate 11.

[0031] The surface layer 10 is bonded to the sound-absorbing plate 21, and the sound waves of noise are introduced into the sound-absorbing plate 21 through the sound-guiding holes 12 opened on the ABS plate 11.

[0032] like Figure 3 As shown, the sound-absorbing layer 20 is formed by stacking two sound-absorbing panels 21 one on top of the other; the sound-absorbing panel 21 includes a fiberboard 211, sound-absorbing holes 212 formed on the fiberboard 211, and sound holes 213 perpendicularly penetrating the sound-absorbing holes 212; the two sound-absorbing panels 21 are stacked with their respective sound holes 213 aligned at the center; the sound-absorbing holes 212 are isosceles trapezoidal structures, and sound waves enter the sound-absorbing holes 212 through the sound holes 213 on the short base side and are discharged through the sound holes 213 on the long base side.

[0033] The silencing plate 21 has a sound hole 213 that passes through the silencing hole 212. The ABS plate 11 is attached to the silencing plate 21 through the sound inlet 12 and the center of the sound hole 213. The sound wave enters through the sound inlet 12, passes through the sound hole 213 and enters the silencing hole 212.

[0034] The silencing hole 212 has an isosceles trapezoidal structure, and the sound wave enters the silencing hole 212 through the sound hole 213 on the short base side and exits through the sound hole 213 on the long base side. When the sound wave enters the silencing hole 212 through the sound hole 213 on the short base side, the sound wave will diffuse in the silencing hole 212. Part of the sound wave will be exited through the sound hole 213 on the bottom side, and the other part of the sound wave will hit the long base side and be reflected back, and collide with and cancel out the sound wave entering from the sound inlet hole 12. Since the silencing plate 21 is provided with two pieces, the sound wave is greatly weakened after passing through the silencing hole 212 twice, which achieves the sound insulation effect.

[0035] like Figure 4 As shown, the cavity layer 30 is composed of three porous plates 31 stacked together, and the holes of the three porous plates 31 are staggered to form a honeycomb structure.

[0036] If the noise is too loud and the sound cannot be completely blocked by the two sound-absorbing plates 21, then when the sound waves enter the cavity layer 30, they will be weakened again by the three porous plates 31 of the honeycomb structure. This design can further enhance the sound insulation effect.

[0037] When the composite board is used in noisy environments, the backing layer 40 can be made of rubber damping plate, so that the sound waves are reduced twice and then further reduced by the rebound effect of the rubber damping plate.

[0038] Through the three-layer noise reduction effect of the sound-absorbing plate 21, the perforated plate 31 and the rubber damping plate, the sound insulation effect can be effectively achieved.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description, and thus all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model. No reference numerals in the claims should be construed as limiting the scope of the claims.
