Abstract

The invention discloses a sound absorption plate, which comprises an intrinsic plate body, wherein grooves are respectively formed on upper and lower layers of the plate body; a foam polystyrene layer is arranged in the plate body; and a mortar layer is arranged on one side of the foam polystyrene layer. In one embodiment of the invention, the grooves which have the same size are uniformly distributed on the upper and lower layers of the plate body. The plate body is in a shape of a square which is 1,200 mm long and 1,200 mm wide. Moreover, sound absorption holes are formed in the foam polystyrene layer. The sound absorption plate is simple in structure and convenient to use, has the advantages of large plate surface, high flatness, high plate material strength, light weight, good sound absorption effect, fireproof performance, waterproof performance and the like, can be completely applied to all fields of life, and facilitates popularization and application.

Description

technical field [0001] The invention relates to an energy-saving material for a room absorption, in particular to a sound-absorbing board. Background technique [0002] The sound-absorbing panel is a plate-shaped material with sound-absorbing and noise-reducing effects. It is mainly used in theaters, concert halls, museums, exhibition halls, libraries, etc. The sound-absorbing panels are installed on the base material, and the grades are classified according to the amount of formaldehyde emitted by the material of the base material. There are a total of E0, E1, and E2. Among them, E0 is the highest level of environmental protection, E1 is second, and E2 has the highest formaldehyde emission. If it is directly used for indoor installation, the E1 level is qualified. For example, the application document with the Chinese application number 200520068118.4 discloses that the sound-absorbing panel belongs to the field of acoustics, especially a sound-absorbing panel for control...
