High-efficiency acoustic panel

Abstract

The invention discloses an high-efficiency acoustic panel, the acoustic panel comprises a first panel, a second panel and an aluminum honeycomb core, wherein the first panel and the second panel are respectively arranged on opposite sides of the aluminum honeycomb core; the aluminum honeycomb core comprises a plurality of spliced sound-absorbing units; the inner wall of each sound-absorbing unit is provided with a resin layer; the resin layer is adhered and fixed with the sound-absorbing unit by resin foaming and curing, and the thickness of the resin layer is 0.3-1mm. By arranging the first panel and the second panel, the installation of the acoustic panel can be facilitated, and the flatness of the surface of the acoustic panel is ensured; the acoustic panel is provided with the aluminumhoneycomb core, and the inner wall of the sound-absorbing unit is provided with a resin layer; therefore, the honeycomb structure has the advantages of good soundproofing effectiveness and relativelyhigh intensity and weight ratio, a requirement of larger intensity can be met by the smaller section, the dead weight of the whole structure can be greatly reduced, furthermore, the sound-absorbing effect of the sound-absorbing unit can be enhanced by the resin layer. Therefore, the high-efficiency acoustic panel has simple integral structure, light weight, good sound absorption and sound insulation effects.

Description

technical field [0001] The invention belongs to a sound insulation product, in particular to a high-efficiency sound insulation board. Background technique [0002] The current indoor and some public place sound insulation methods usually use some traditional materials such as ordinary decorative wood boards, and the materials are installed on the ceiling, wall and ground substrates of the building. The following situations often occur in this method: the material density is relatively low, and the sound insulation is poor; the material is not selected according to the propagation speed of the sound in various media, so there is no obvious sound insulation effect. And for production equipment, etc., there is a lot of noise during processing, and this type of noise is usually not dealt with, making the working environment noisy and increasing the discomfort of workers. Contents of the invention [0003] The object of the present invention is to provide a high-efficiency so...
