Super-microporous sound absorption board

Abstract

The invention discloses a super-microporous sound absorption board. The super-microporous sound absorption board comprises a surface layer, a base material and a sound absorption layer, wherein super-micropores are densely distributed in the surface layer and penetrate through the surface layer; the base material is made of a flame-retardant material, a plurality of through holes are distributed in the base material in an arrayed mode, and the through holes communicate with the super-micropores within the outer contour range of the through holes; the sound absorption layer is made of a sound absorption material; and the surface layer and the sound absorption layer are fixed to the two sides of the base material in an attached mode correspondingly. The super-microporous sound absorption board is based on the cavity resonance sound absorption principle, the two sides of the base material are covered with the surface layer and the sound absorption layer, thus the through holes in the basematerial are turned into resonance cavities with supermicro sound inlets, sound wave energy can be effectively counteracted through the resonance effect and the sound absorption effect of the sound absorption layer, the good sound absorption effect is achieved, and the super-microporous sound absorption board is simple in structure, low in cost and suitable for a multifunction hall, an opera house, a conference room, a cinema, an auditorium, a hotel, a television station, a concert hall, a piano room, a villa or a place with the strict requirement for the acoustic effect in the home life.

Description

technical field [0001] The invention relates to the field of sound-absorbing panels, in particular to an ultra-microporous sound-absorbing panel. Background technique [0002] Sound-absorbing panels are a commonly used sound-absorbing decorative material. They can not only absorb sound, but also play a decorative role. They are often used in homes, shopping malls, classrooms and other occasions. The existing sound-absorbing panels on the market are generally relatively simple in structure. , can play a simple role in sound absorption, but it cannot be used in multi-functional halls, opera houses, conference rooms, cinemas, auditoriums, hotels, TV stations, concert halls, piano rooms and other occasions that require high sound absorption. It is suitable for these The sound-absorbing panels in various places are often complex in structure and expensive. Contents of the invention [0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the p...
