Embodiment 1

[0015] Such as Figure 1-2 As shown, the present application relates to a sound insulation and noise reduction board, the sound insulation and noise reduction board comprises from bottom to top: sound-absorbing cotton 2 and sound-absorbing board 3, the sound-absorbing cotton and the sound-absorbing board are bonded by glue, the bottom and sides of the sound-absorbing cotton, The sides of the sound insulation panels are all wrapped and pasted with wall cloth 1; wherein, the sound-absorbing cotton is glass wool, and the sound insulation panels are metal honeycomb panels. The three-layer structure of wall covering, sound-absorbing cotton and sound-absorbing board, wall covering and sound-absorbing cotton can play the role of sound absorption, and the sound-absorbing board has a better sound insulation effect. The honeycomb core structure in the metal honeycomb panel can form an air sound insulation layer, which can better achieve sound insulation effect. The wall covering is sof...

Embodiment 2

[0020] This embodiment relates to a sound-insulating and noise-reducing panel. The technical solution of the sound-insulating and noise-reducing panel adds the following technical features on the basis of Example 1:

[0021] 1. Embed sound-proof cotton in the sound-absorbing cotton; the thickness of the sound-proof cotton is 1-2cm, and the plane area of ​​the sound-proof cotton is more than 50% of the area of ​​the sound-absorbing cotton. Optimally, the cross-sectional area of ​​the sound-insulating cotton is 70% of the cross-sectional area of ​​the sound-absorbing cotton.

[0022] 2. Rubber blocks are embedded in the sound insulation cotton. The role of the rubber block is mainly to make the structural system more stable.

[0023] In Example 2 of this application, the combination of wall covering, sound-absorbing cotton, sound-insulating cotton, and sound-insulating panels is adopted, and the honeycomb structure in the sound-insulating panel, the honeycomb structure in the m...

Abstract

The invention discloses a sound insulation and noise reduction plate. The sound insulation and noise reduction plate sequentially comprises sound absorption cotton and a sound insulation plate from bottom to top, the sound absorption cotton and the sound insulation plate are bonded through an adhesive, and the bottom face and the side face of the sound absorption cotton and the side face of the sound insulation plate are wrapped and bonded with wall cloth. The sound absorption cotton is glass silk floss, and the sound insulation plate is a metal honeycomb plate. The technical problem that a sound insulation and noise reduction plate is poor in sound insulation and noise reduction effect is solved.

Description

technical field [0001] The application relates to the technical field of sound insulation and noise reduction in office spaces or exhibition and conference venues, and specifically relates to a new type of sound insulation and noise reduction board. Background technique [0002] In public or private places such as office meeting places and exhibition venues, solid partition wall systems and light steel keel partition wall systems are more common. In order to solve the problem of indoor sound absorption, sound-absorbing cotton is generally pasted on the surface of the keel or partition wall. , so as to play the function of sound absorption and noise reduction. This structure can achieve a certain sound absorption effect, but the effect is not very good. And the effect of some existing sound insulation and noise reduction panels is not very good. Moreover, there are some high-demand office spaces or conference halls, and some existing noise-reducing panels cannot meet the re...
