Embodiment Construction

[0013] Such as figure 1 figure 2 As shown, the micro-perforated sound-absorbing aluminum hollow composite panel is a composite panel with a three-layer structure, including a surface layer 1, an intermediate layer 2 and a base layer 3, characterized in that: the surface layer 1 and the base layer 3 are The surface of the aluminum plate is provided with many misplaced micro-perforations 4; the middle layer 2 is a modified polyphenylene ether (MPPO) plastic plate, and a plurality of hollow holes 5 are arranged in the plastic plate.

[0014] The thickness of the aluminum plate of the surface layer 1 and the base layer 3 is 0.5mm-1.0mm; the thickness of the modified polyphenylene ether plate of the middle layer 2 is 6.0mm-10mm.

[0015] The pore diameter of the micro-perforation 4 is not greater than 1.0mm, the hole distance is 4mm-6mm, and the perforation rate is 1-5%.

[0016] The hollow holes 5 in the modified polyphenylene ether plastic plate of the middle layer 2 are compo...

Abstract

The invention relates to a sound-absorbing board used in construction, in particular to a micro-perforated sound-absorbing aluminum hollow composite board. It includes a surface layer, a middle layer and a base layer. The surface layer and the base layer are aluminum plates, and there are many micro-perforations arranged in dislocation on the surface of the aluminum plate; the middle layer is a modified polyphenylene ether (MPPO) plastic plate, and there are multiple Hollow hole; the thickness of the surface layer and base aluminum plate is 0.5mm-1.0mm, the thickness of the intermediate layer modified polyphenylene ether plate is 6.0mm-10mm; the aperture of the micro-perforation is not more than 1.0mm, and the hole distance is 4mm- 6mm, and the perforation rate is 1-5%. The hollow hole 5 in the modified polyphenylene ether plastic plate of the middle layer is composed of a plurality of rectangular holes of the same size and shape arranged in parallel. The present invention has high sound absorption coefficient, high middle and low frequency sound absorption performance, and has the advantages of light weight, high strength, high temperature resistance, moisture resistance and corrosion resistance, as well as longer service life and better decoration .

Description

technical field [0001] The invention relates to a sound-absorbing board used in construction, in particular to a micro-perforated sound-absorbing aluminum hollow composite board with micro-perforations on the surface and a sandwich structure. Background technique [0002] Sound-absorbing panels are widely used in concert halls, theaters, recording studios, studios, conference rooms, gymnasiums, exhibition halls, dance halls, KTV rooms and other public places on the ground, walls and ceilings. The sound-absorbing panels can absorb noise well and prevent strong indoor sound from affecting the indoor environment, so that you can get good sound quality when you have a meeting, listen to a report or enjoy music. There are many types of sound-absorbing panels, such as plant fiber acoustic panels, glass fiber acoustic panels, polyester fiber acoustic panels, aluminum acoustic panels, etc. Which kind of sound-absorbing board to choose should first determine the required board from ...
