Sound absorption heat-insulation plate

Abstract

The invention discloses a sound absorption heat-insulation plate, which comprises seven layers of structures, wherein the middle layer is a layer of metal plate, wherein the upper surface and the lower surface of the metal layer are respectively provided with a sound absorption heat-insulation layer, the upper surface and the lower surface of the sound absorption heat-insulation layer are respectively provided with non-woven fabric layers, and the upper surface and the lower surface of the non-woven fabric layer are respectively provided with polyester glass fiber plates. The sound absorption heat-insulation layer adopts hexagonal honeycomb cores made of PVC (polyvinyl chloride), sound absorption materials such as rock wool or perlite are filled in the hexagonal honeycomb cores, sound waves pass through the non-woven fabric layer and are absorbed by the sound absorption materials in the hexagonal honeycomb cores, the sound absorption effect is reached, the sound absorption heat-insulation plate can be used for sound absorption suspended ceilings and wall surfaces of public places, such as airport terminals, stadiums and conference halls, the noise reduction coefficient is high and can reach more than 0.8, the sound absorption heat-insulation plate can be used for manufacturing the large-area wide plate suspended ceiling, the appearance is attractive, the weight is light, the deformation is avoided, and the popularization is convenient.

Description

technical field [0001] The invention relates to a board, in particular to a sound-absorbing and heat-preserving board, which belongs to the field of heat-preserving materials. Background technique [0002] At present, honeycomb panels are mostly used in thermal insulation panels for building exterior walls, ceilings, interior wall partitions, and large roofs. Honeycomb panels are light, high-rigidity panels that have a wide range of applications. . Existing thermal insulation honeycomb panels, which include a surface board, a middle board and a bottom board, a honeycomb support is arranged longitudinally between the surface board and the middle board, a heat insulation layer is arranged between the middle board and the bottom board, and the surface layer The board, the middle board and the bottom board are connected by heat insulation components, so that the honeycomb board has more thermal insulation performance on the basis of its original advantages. However, although t...
