Problems solved by technology

[0003] At present, porous sound-absorbing materials made of polymer materials are the most used in the field of sound-absorbing bodies, such as: glass wool, melamine and other porous sound-absorbing materials. After using porous sound-absorbing materials, the following problems are found: There is secondary pollution in the process, and the waste after construction cannot be disposed of, polluting the environment again
As time goes by, porous materials will gradually pulverize, fine fibers will be precipitated into the air, causing very serious damage to human respiratory organs, and the support strength is low, so they cannot be recycled and can only be scrapped and discarded. Not only waste, Not environmentally friendly, waste of resources

Embodiment Construction

[0024] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, but not to limit the present invention.

[0025] like Figure 1 to Figure 5 As shown, the present invention preferably implements a foamed aluminum sound absorber, which includes a sound absorber body, and the sound absorber body includes a foamed aluminum block 1. The foamed aluminum block 1 is formed by adding additives to pure aluminum or aluminum alloy, and then undergoing a foaming process. It has the characteristics of sound absorption and reflection, low density, high shock absorption ability, high temperature resistance, etc., which also has the effect of improving the overall support strength, and can also be recycled and rebuilt, which is green and environmentally friendly. The aluminum foam block 1 is wrapped...

Abstract

The invention provides a foamed aluminum sound absorber, and relates to the technical field of sound absorbing materials. The foamed aluminum sound absorber comprises a sound absorber body, the soundabsorber body comprises a foamed aluminum block, a punched metal plate wraps the foamed aluminum block, the thickness of the punched metal plate is 5 mm to 10 mm, a sound absorbing non-woven fabric isarranged on the inner wall of the punched metal plate, the thickness of the sound absorbing non-woven fabric is 0.06 mm to 0.08 mm, a cavity is formed between the foamed aluminum block and the punched metal plate, and the width of the cavity is 15 mm to 20 mm. The invention has the beneficial effects of being light in structure, capable of being recycled, green and environment protective, high insupporting strength and convenient to assemble and disassemble.

Description

technical field [0001] The invention relates to the technical field of sound-absorbing materials, in particular to a foamed aluminum sound-absorbing body. Background technique [0002] In the field of sound construction, in order to reduce the reverberation sound in the room and achieve the purpose of improving the sound quality, it is often necessary to lay a sound absorbing body in the room. Especially for theaters, conference halls, stadiums, etc. with high sound quality requirements, there are strict requirements on the sound absorption performance of sound absorbing bodies. The sound absorption frequency band of the sound absorbing body is required to be wide, especially the low frequency sound absorption performance is better. In the general industrial field, in order to reduce the noise sound pressure level in the room, it is often necessary to lay a sound absorber in the workshop to reduce the reflected sound, thereby solving the additional sound pressure level caus...
