AI Technical Summary
The sound penetration problem of existing sound-absorbing boards at the splicing point leads to unsatisfactory noise isolation.
The design of a particle sandstone sound absorbing plate is adopted, including a substrate layer, a first sandstone layer and a second sandstone layer. The sound absorbing effect at the splicing is enhanced by setting the first splicing edge, the second splicing edge and the grooves filling the third sandstone.
It effectively reduces the spread of sound through the gaps at the splicing and improves the overall sound absorption effect of the sound-absorbing board.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of decorative plates, in particular to a particle sandstone sound-absorbing plate. Background Art
[0002] A new material has emerged in the field of decorative panels, namely sound-absorbing panels, which refer to plate-shaped materials that have sound-absorbing and noise-reducing properties.
[0003] The principle of sound-absorbing panels: There are many small holes on the surface of the sound-absorbing panels. When the sound enters the small holes, it will be randomly reflected in the inner wall whose structure is a bit like a sponge until most of the energy of the sound waves is consumed and converted into heat energy, thus achieving the effect of sound insulation.
[0004] At present, the effects of sound-absorbing panels on the market are not very ideal, especially at the joints of the sound-absorbing panels, where sound can be transmitted directly through the gaps at the joints. Summary of the invention
[0005] The utility model mainly solves the above problems and provides a particle sandstone sound-absorbing board.
[0006] The technical solution adopted by the utility model to solve its technical problem is a kind of fine sandstone sound-absorbing board, comprising a substrate layer, a first sandstone layer and a second sandstone layer stacked in sequence, the upper half of the first side of the substrate layer is provided with a first splicing edge, the lower half of the second side of the substrate layer is provided with a second splicing edge, the first splicing edge is complementary to the second splicing edge, and a groove is provided at the connection between the first splicing edge and the second splicing edge and the substrate layer, and the groove is filled with a third sandstone.
[0007] As a preferred embodiment of the above scheme, the substrate layer is formed by hot pressing of ceramsite.
[0008] As a preferred embodiment of the above scheme, the first sandstone layer is fine-grained coarse sandstone.
[0009] As a preferred embodiment of the above scheme, the second sandstone layer is fine-grained sandstone.
[0010] As a preferred embodiment of the above scheme, the third sandstone is micro-coarse sandstone, micro-fine sandstone or a mixture of micro-coarse sandstone and micro-fine sandstone.
[0011] As a preferred embodiment of the above scheme, a mesh cloth is provided on the substrate layer, and the first sandstone layer is sprayed on the mesh cloth.
[0012] The advantages of the utility model are: there are multiple gaps in the base plate layer, the first sandstone layer and the second sandstone layer, all of which can play a role in sound absorption, and the combination of the three has a good sound absorption effect; a first splicing edge and a second splicing edge are provided, and a groove filled with a third sandstone is provided, so that the sound absorption effect of the splicing of the sound-absorbing board is enhanced, and the sound is prevented from being transmitted from the gaps at the splicing of the sound-absorbing board.

[0016] Example:
[0017] This embodiment is a particle sandstone sound absorbing board, such as Figure 1 As shown, it includes a substrate layer 1, a first sandstone layer 3 and a second sandstone layer 4 stacked in sequence, a mesh cloth 2 is provided on the substrate layer 1, the first sandstone layer 3 is sprayed on the mesh cloth, and the second sandstone layer 4 is applied on the first sandstone layer. A first splicing edge 5 is provided on the upper half of the first side of the substrate layer 1, and a second splicing edge 6 is provided on the lower half of the second side of the substrate layer 1. The first splicing edge 5 and the second splicing edge 6 are complementary, and a groove is provided at the connection between the first splicing edge 5 and the second splicing edge 6 and the substrate layer 1, and the groove is filled with a third sandstone 7.
[0018] The substrate layer 1 is formed by hot pressing of ceramsite, the first sandstone layer 3 is coarse sandstone, the second sandstone layer 4 is fine sandstone, and the second sandstone is coarse sandstone, fine sandstone, or a mixture of coarse sandstone and fine sandstone. Fine sandstone is sandstone with a particle diameter less than a threshold value in the fine sandstone, and coarse sandstone is sandstone with a particle diameter greater than a threshold value in the fine sandstone. The threshold value can be adjusted accordingly according to demand.
[0019] The substrate layer, the first sandstone layer, and the second sandstone layer of the micro-sandstone sound-absorbing board of this embodiment form three sound-absorbing layers with different sound-absorbing holes inside, which can absorb sound waves of different frequencies respectively and have good sound-absorbing effect. In addition, a first splicing edge and a second splicing edge are respectively provided on both sides of the sound-absorbing board, and a groove filled with a third sandstone is provided at the connection between the splicing edge and the substrate layer to enhance the sound-absorbing effect at the splicing of the sound-absorbing board and prevent the sound from being transmitted from the gap at the splicing of the sound-absorbing board.
