The acoustic composite board which has the advantages of light weight, high intensity, favorable effect on sound absorption, sound insulation and fire retardant, easy production, and easy processing is formed by bonding a closed-pore foam aluminum sheet and a back board with adhesives. As one service application of the acoustic composite board, the sound insulation screen produced by the same comprises a metal structure component, the acoustic composite board, a transparent body and a cement guard bar. The sound insulation screen with the advantages of beautiful appearance, hard aging and long service life is suitable for using in the both sides of elevated high speed roads and elevated light rail roads and construction sites to achieve the goal of preventing and eliminating noise pollution.
Description
Technical field: the utility model relates to the device that abates the noise material in traffic, the environmental protection field and make with this material, especially for overhead, super expressway two take up building site etc. prevent or eliminate that noise pollution adopts have sound absorption and the composite plate of sound insulation function and the acoustic screen of making by this composite plate concurrently.
Background technology: construction site such as building all can produce severe noise and pollutes in vehicle that travels in the urban roads such as speedway, overhead speedway, elevated railway and the urban district, causes adverse effect for people's work and life even health.For this reason, around road both sides and building site, need to be provided with some sound insulations, sound-absorbing facility, to reduce noise pollution.The patent No. is that the utility model patent of 98225265.X discloses a kind of sound barrier by the foamed aluminium material preparation, its foamed aluminium board and backboard with 40 * 50cm is made the compoboard that is of a size of 20-100cm, the sound barrier of manufacturing is spliced by such compoboard, makes this sound barrier lack effective sound insulation function.
Summary of the invention: the purpose of this utility model is to provide a kind of sound absorption and soundproof effect good, practical, the acoustic screen of making simple sound absorption composite plate and being made by this material.
The utility model is achieved through the following technical solutions:
The sound absorption composite plate is made of foamed aluminium board and backboard.Wherein foamed aluminium board is raw material with the closed-cell aluminum foam, with adhesive closed-cell foam aluminium sheet and backboard is bonded together, and forms composite board.
Acoustic screen by the preparation of sound absorption composite plate comprises sound absorption material plate, decorative panel, basic fixture and hardware.Hardware will be as the sound absorption composite plate of sound absorption material plate, be fixed into one from top to bottom as the transparent body of decorative panel with as the Cement guard bar of basic fixture.
Characteristics such as the closed-cell aluminum foam that the utility model adopted utilizes melt foaming method preparation, and it is big that this closed-cell aluminum foam has size, and adjustable density, intensity are big.So-called closed pore is meant that the pore of 70%-98% is the single hole of round sealed in the foamed aluminium, and what the sound absorption sound insulation materials was selected for use is that density is 0.2-0.6g/cm
3, the aperture is 1mm-6mm, by the closed-cell aluminum foam of metal aluminum or aluminum alloy preparation.The thickness of foamed aluminium material can be selected, adjust in the 10mm-50mm scope according to field requirement.
Owing to the characteristics and the reasons such as cutting, processing of closed-cell aluminum foam, the foamed aluminium material surface distributed a large amount of open pores, i.e. half hole.Half hole of these different sizes, different depth has formed the three-dimensional structure on foamed aluminium surface, and this structure helps decay and the absorption of foamed aluminium material for sound; Because the metal bubble structure of closed-cell aluminum foam inside has good reflection and insulating effect for sound, like this, closed-cell aluminum foam has absorption and intercepts double action sound, and is very favourable to reducing noise pollution simultaneously.After measured: in the 500Hz-1600Hz audiorange, the sound absorption coefficient of closed-cell aluminum foam is 40%-60%, and thickness is that the sound transmission loss of the closed-cell foam aluminium sheet of 20mm is the 30-50 decibel.
But for strengthening intensity stationarity, the weatherability and ornamental of closed-cell foam aluminium sheet, adopting thickness is that 1mm-5mm aluminium, steel plate or glass epoxy are as backboard.The closed-cell foam aluminium sheet coheres with high-strength structureal adhesives and backboard after rolling, and this has just formed the composite plate with sound absorption, sound insulation function.Can also be as required, but use metal or macromolecular material to strengthen the globality and the stationarity of sound absorption composite plate as securing member.The monolithic standard size of this sound absorption composite plate is 800mm * 1800mm, can be cut into the fritter sheet material of any size in this scope, and sliceable use; This sound absorption composite plate can also be processed into different shape, and can be crooked, knuckle makes various sound absorptions, sound arrester to be applicable to.
One of purposes of this sound absorption composite plate is the acoustic screen that preparation has sound absorption, sound insulation effect.This acoustic screen is made up of sound absorption and insulation plate of material, decorating material board, basic fixture and structural meterials.Wherein the sound absorption and insulation plate of material just is to use this sound absorption composite plate; What decorating material board was selected for use is the transparent body, can adopt glass, organic glass or other organic transparent materials, plays decoration function, and certain sound insulation function is also arranged; Basic fixture will be in conjunction with the field condition of noise source, and the basis of laying for acoustic screen provides, fixing is as the Cement guard bar of road both sides such as super expressway, overhead speedway, elevated railway.Structural meterials plays the effect of installation, connection sound absorption composite plate and the transparent body usually based on metal material, again they and Cement guard bar is fixed into one.Structural meterials can directly be imbedded Cement guard bar or adopt bolt to be connected with Cement guard bar.
The advantage of the sound absorption composite plate that the utility model is prepared is: light weight, intensity height, sound absorption and insulation is effective and fire-retardant, and makes simple, easy to process; The acoustic screen cost of production that the composite plate that absorbs sound is thus made is low, both artistic and practical, is suitable for large tracts of land and installs, and is difficult for during use wearing out, and the life-span is long.
