Sound-absorbing aluminum plate

Abstract

The invention discloses a sound-absorbing aluminum plate comprising an upper aluminum plate layer, a lower aluminum plate layer and a middle aluminum plate layer connected between the upper aluminum plate layer and the lower aluminum plate layer. The upper aluminum plate layer comprises a basic aluminum plate and an aluminum sheet arranged on the surface of the basic aluminum plate, the middle aluminum plate layer is corrugated, bubble holes in irregular arrangement are formed in the corrugated surface of the middle aluminum plate layer, and both the basic aluminum plate and the lower aluminum plate layer are foam aluminum plates. The sound-absorbing aluminum plate is good in sound absorption function, high in appearance decorativeness, high in rigidity and large in application range, and has good application prospect.

Description

technical field [0001] The invention belongs to the technical field of functional materials, and in particular relates to a sound-absorbing aluminum plate. Background technique [0002] In cities full of high-rise buildings and noisy cars, people have higher and higher requirements for the quietness of the environment. No matter in the working environment or when resting, the noisy environment will have a greater impact on people's body and mind. Life brings a relatively large negative effect, which requires the selection of materials with better sound-absorbing performance when manufacturing and decorating buildings. Aluminum panels are often used in people's interior decoration such as ceilings and walls. Existing aluminum panels have many functions, but The improvement of the sound-absorbing function of the aluminum plate needs to be further strengthened, and at the same time, the rigidity of the aluminum plate must be further improved.
