Description

Technical Field

[0001] The utility model relates to the technical field of sound insulation devices, in particular to a high-efficiency composite sound-absorbing and sound-insulating board. Background Art

[0002] Sound insulation board is a kind of plate that acts on the sound insulation effect. It is classified into building sound insulation and structure sound insulation. Sound insulation board can not block all frequencies of sound. Objects have inherent resonance frequency. The sound insulation effect of sound insulation board is significantly reduced for the sound close to the resonance frequency of the object. Sound insulation board is divided into air sound insulation and vibration sound insulation. Air sound insulation board is a board that blocks the sound propagating in the air. Vibration sound insulation board is a board and system that blocks the sound propagating in rigid components (such as reinforced concrete monolithic houses). The material with a greater difference in density from air is generally a material with a very high density (there are not many materials with much lower density than air except vacuum), which can be regarded as sound insulation material. The higher the density, the better the sound insulation effect. The board made of such material is called sound insulation board;

[0003] The current sound insulation board requires a large amount of adhesive to fix it during installation due to its flat side structure, and the adhesive takes a certain amount of time to fix, which affects its installation efficiency. At the same time, the raw material of the current sound insulation board is made of asbestos, which is very harmful to the human body. If accidentally inhaled during installation, it is easy to cause a series of lung diseases.
