Description

Technical Field

[0001] The utility model relates to the technical field of PVC foam boards, in particular to a sound-insulating PVC foam board. Background Art

[0002] PVC foam board is also called Chevron board and Andy board. Its chemical composition is polyvinyl chloride, so it is also called foam polyvinyl chloride board. It is widely used in the fields of passenger cars, train compartment ceilings and box core layers. However, the existing PVC foam board cannot soundproof the external environment well, making the internal environment easily affected by the outside world, resulting in poor sound insulation effect. At the same time, PVC foam board is easy to be deformed in subsequent use, and PVC foam board is difficult to adapt to the use of different occasions, which makes the PVC foam board less practical. Utility Model Content

[0003] In view of this, the utility model provides a sound-insulating PVC foam board, which can further soundproof the PVC foam board, enhance the sound insulation effect of the PVC foam board, withstand greater bending forces, and adapt to use in different occasions, thereby improving the sound insulation effect and practicality of the PVC foam board.

[0004] The technical solution is: a sound-insulating PVC foam board, comprising a first supporting board, a PVC foam board, a first sound insulation board, a supporting member, a second sound insulation board, a second supporting board, a fixing layer and a wear-resistant layer. PVC foam boards are arranged on both sides of the first supporting board, and the two PVC foam boards are symmetrically arranged. The first sound insulation board is arranged on the side away from each other of the two PVC foam boards, and a plurality of supporting members are arranged on the side away from each other of the two first sound insulation boards, and a plurality of supporting members located on the same first sound insulation board form a group, and a second sound insulation board is arranged on the side away from each other of the two groups of supporting members, and the two second sound insulation boards are symmetrically arranged. The second supporting board is arranged on the side away from each other of the two second sound insulation boards, and the fixing layer is arranged on the side away from each other of the two second supporting boards, and the wear-resistant layer is arranged on the side away from each other of the two fixing layers.

[0005] Furthermore, the plurality of support members are arranged in a ring shape, and the plurality of support members are elastic.

[0006] Furthermore, the two fixing layers are both polyester sheets.

[0007] Furthermore, the two wear-resistant layers are both made of aluminum oxide.

[0008] The beneficial effects are as follows: in the utility model, a vacuum space is formed between the first sound insulation board and the second sound insulation board to enhance the sound insulation effect of the PVC foam board. At the same time, a first support plate is provided between the two PVC foam boards, so that the two PVC foam boards can bear a greater bending force, and the two fixing layers can further block noise for the PVC foam boards. The wear-resistant layer enables the PVC foam board to adapt to use in different occasions, thereby improving the practicality of the PVC foam board. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0013] Embodiment 1: A sound-insulating PVC foam board, such as Figure 1-Figure 2 As shown, it includes a first support plate, a PVC foam plate, a first sound insulation plate, a support member, a second sound insulation plate, a second support plate, a fixing layer and a wear-resistant layer. The first support plate is fixedly connected with PVC foam plates on both sides, and the two PVC foam plates are symmetrically arranged. The two PVC foam plates are connected to the first sound insulation plate on the sides away from each other by rivets. The two first sound insulation plates are connected to a plurality of support members on the sides away from each other by bolts. The plurality of support members on the same first sound insulation plate form a group. The two groups of support members are connected to the second sound insulation plate on the sides away from each other by rivets. The two second sound insulation plates are symmetrically arranged. The two second sound insulation plates are fixedly connected with the second support plate on the sides away from each other. The two second support plates are provided with a fixing layer on the sides away from each other, and the two fixing layers are provided with a wear-resistant layer on the sides away from each other.

[0014] Furthermore, the plurality of support members are arranged in a ring shape, and the plurality of support members are elastic.

[0015] Furthermore, the two fixing layers are both polyester sheets.

[0016] Furthermore, the two wear-resistant layers are both made of aluminum oxide.

[0017] In the utility model, a plurality of supporting members are arranged between the first sound insulation board and the second sound insulation board, and the plurality of supporting members are all in an annular structure, so that a vacuum space is formed between the first sound insulation board and the second sound insulation board, forming a double-layer sound insulation structure, and enhancing the sound insulation effect of the PVC foam board. At the same time, by arranging the first supporting plate between the two PVC foam boards, the two PVC foam boards can bear a greater bending force, and deformation of the foam boards in subsequent use can be avoided as much as possible. Moreover, the two fixing layers are both polyester sheets, which can further block noise for the PVC foam boards and prevent the internal environment from being affected by the outside world. The wear-resistant layer gives the surface of the PVC foam board important properties such as wear resistance, scratch resistance, corrosion resistance and moisture resistance, so that the PVC foam board can adapt to the use of different occasions, and improve the practicality of the PVC foam board.

[0018] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
