Abstract
The invention relates to a sound-absorbing plate used on a building, in particular to a micro-perforated sound-absorbing aluminum hollow compound plate. The micro-perforated sound-absorbing aluminum hollow compound plate comprises a surface layer, an intermediate layer and a base layer, wherein the surface layer and the base layer are aluminum plates, and a plurality of micro-perforated holes in dislocated arrangement are arranged on the surfaces of the aluminum plates; the intermediate layer is a modified polyphenylene oxide (MPPO) plastic plate, and a plurality of hollow holes are arranged in the plastic plate; the thickness of the aluminum plates of the surface layer and the base layer is 0.5mm-1.0mm, the thickness of the modified polyphenylene oxide plate of the intermediate layer is 6.0mm-10mm; the aperture of the micro-perforated holes is not more than 1.0mm, the hole pitch is 4mm-6mm and the perforation rate is 1-5%; and the hollow holes 5 in the modified polyphenylene oxide plate of the intermediate layer comprise a plurality of rectangular holes with the same size and the shape, which are arranged into a row in parallel. The micro-perforated sound-absorbing aluminum hollow compound plate has very high coefficient of sound absorption and higher medium and low-frequency sound-absorbing performance; simultaneously, the micro-perforated sound-absorbing aluminum hollow compound plate has the advantages of light weight, high strength, high temperature resistance, moisture protection and corrosion prevention, as well as longer service life and better decorative property.
Description
Technical field
The present invention relates to a kind of sound absorbing plate of architectural usefulness, particularly relate to the micropunch sound absorption aluminium Hollow composite board that there is micropunch on a kind of surface and has sandwich.
Background technology
Acoustical board is widely used in concert hall, cinema, recording room, performs in a radio or TV programme on ground, metope and the ceiling in public places such as the Room, conference room, sports palace, exhibition hall, dancing hall, karaoke chamber.Acoustical board can the good absorption noise and is prevented that indoor sound is strong and influence indoor environment, allow you in session, listen and report or can obtain good acoustical quality during music appreciating.The kind of acoustical board is a lot, as string acoustical board, glass fiber acoustical board, polyester fiber acoustical board, aluminium matter acoustical board etc.Select which kind of acoustical board for use, at first should determine the sheet material that meets the requirements, also will take all factors into consideration and select simultaneously in conjunction with specific requirements such as fire prevention, corrosion-resistant, high temperature resistant, intensity, outward appearance, project installation constructions from the sound absorption characteristics aspect.Existing many acoustical boards etc., though certain advantage is all arranged separately, when taking all factors into consideration, the some shortcomings part is arranged all more or less but, so the combination property that how further to improve existing acoustical board is that the building finishing field needs the conscientiously technical problem of solution.
Summary of the invention
The objective of the invention is in order to overcome the existing not good enough defective of acoustical board resultant effect existing aluminium matter acoustical board to be improved, develop a kind of micropunch sound absorption aluminium Hollow composite board, this Hollow composite board has higher medium and low frequency sound absorbing capabilities.
The objective of the invention is to realize as follows: described micropunch sound absorption aluminium Hollow composite board, it is a kind of composite board with three layer construction, comprise surface course, intermediate layer and basic unit, it is characterized in that: described surface course and basic unit are aluminium sheets, are provided with the micropunch that many dislocation are arranged in surface of aluminum plate; The intermediate layer is Noryl (MPPO) plastic plate, is provided with a plurality of hollow holes in the plastic plate.
The thickness of described surface course and basic unit's aluminium sheet is 0.5mm-1.0mm; The thickness of intermediate layer Noryl plate is 6.0mm-10mm.
The aperture of described micropunch is not more than 1.0mm, and pitch-row is 4mm-6mm, and perforated percentage is 1～5%.
Good effect of the present invention is as follows: 1, owing to be provided with the micropunch that dislocation is arranged at surface course with above the basic unit, so when sound wave passes through this composite plate, sound wave will be propagated along hole wall, and rub with hole wall, make acoustic energy be transformed into heat energy; Simultaneously, when sound wave will produce diffraction during by micropunch, make to produce reflection mutually in the hollow hole of sound wave in Noryl and offset, so the present invention has very high sound absorption coefficient.2, because the employing aluminium sheet is made top layer, noryl plastic plate as the intermediate layer, so this composite plate has light weight, high strength, high temperature resistant, moistureproof, etch-proof advantage simultaneously, and more permanent application life and better ornamental.3, the aperture and the perforated percentage that adopt of micropunch has direct relation to the sound absorbing capabilities of acoustical board, and aperture of the present invention and perforated percentage make it have higher medium and low frequency sound absorbing capabilities.

The thickness of described surface course 1 and basic unit's 3 aluminium sheets is 0.5mm-1.0mm; The thickness of intermediate layer 2 Noryl plates is 6.0mm-10mm.
The aperture of described micropunch 4 is not more than 1.0mm, and pitch-row is 4mm-6mm, and perforated percentage is 1～5%.
Composite plate in the present embodiment, its thickness are 7.5mm; It is the aluminium sheet of 0.5mm that surface course 1 and basic unit 3 all select thickness of slab for use, and the micropunch aperture on the aluminium sheet is 1mm, and pitch-row is 5mm, and perforated percentage is 2%. It is the noryl plastic hollow sheeting of 6.4mm that thickness is selected in the intermediate layer 2 of present embodiment for use, the hollow hole in the plastic plate, by be arranged in delegation, cross section is rectangle and the identical rectangular opening of size is formed.
