Abstract
The invention discloses a kind of effective foamed aluminium abatvoix for mitigating urban traffic noise, including aluminium sheet ontology, it is pasted with foamed aluminium material in the both side surface of the aluminium sheet ontology, which includes following raw material：Aluminium skimmings, deionized water, ultra-pure water, absolute ethyl alcohol, dispersant, plasticizer, adhesive, foaming agent；Adhesive is made of following raw material：Starch, polyvinyl alcohol, polyurethane, butyl rubber, vinyl acetate resin, waterborne organic silicon epoxy resin；Foaming agent is made of following raw material：Azodicarbonamide, sodium bicarbonate, carbon black, n-hexane, Arcton 11, lauryl sodium sulfate；The through-hole porosity of foamed aluminium material is 98.5% 99.8%, 0.75 0.85mm of through-hole aperture average out to；The thickness for the foamed aluminium material pasted in the both side surface of aluminium sheet ontology is 20 25mm；The acoustic absorptivity of foamed aluminium abatvoix is 0.88 0.92.The present invention solves existing foamed aluminium material there are through-hole aperture sizes the technical problem uneven, through-hole aperture is larger, through-hole porosity is relatively low.
Description
Technical field
The present invention relates to new material technology field, specially a kind of effective foamed aluminium abatvoix for mitigating urban traffic noise
And preparation method thereof.
Background technology
With the development of economy, scale of urbanization expands, and the main line of communication rapidly develops, and motor vehicles number is drastically in city
Increase, traffic noise has become the main noise in city.
Porous metals are made of metallic framework and hole, the basic metal properties such as solderability with metal material.
Relative to compact metal material, it is internal with a large amount of hole that porous metals are noteworthy characterized by it.And a large amount of internal void
Make porous metal material that there are many excellent characteristics again.The porous organic polymer strength of materials is low and non-refractory, porous pottery
Then matter is crisp and not anti-thermal shock for porcelain, and therefore, porous metal material is applied in noise reduction technical process, makes muffler.
Foamed aluminium as a kind of porous metal material, with excellent physical property, chemical property and mechanical property with
And recuperability.These excellent properties of foamed aluminium make it have broad application prospects in current Material Field, are to have very much
Develop the new engineering material of future.Foamed aluminium can be used for the noise of urban light rail, sky way, subterranean tunnel, mechanical equipment
Improvement and the improvement of acoustical chamber, multifunctional hall and other acoustics of room effects.The foamed aluminium of sound absorption pastes concrete or steel knot
On structure, erects in overpass, light rail both sides as large-scale sound-absorbing wall, urban traffic noise can be mitigated.
But existing foamed aluminium material that there are through-hole aperture sizes is uneven, through-hole aperture is larger, through-hole porosity compared with
Low problem, these problems have seriously affected the sound-absorbing effect of foamed aluminium material.
Invention content
(1) the technical issues of solving
In view of the deficiencies of the prior art, the present invention provides a kind of effective foamed aluminium abatvoixs for mitigating urban traffic noise
And preparation method thereof, have the advantages that improving through-hole porosity, reducing through-hole aperture and significantly improve acoustic absorptivity, solves existing

1-2 parts of hydrogen sodium, 12-15 parts of carbon black, 1-2 parts of n-hexane, 2-3 parts of Arcton 11,5-6 parts of lauryl sodium sulfate, in temperature
At 35-40 DEG C, mixing speed 500-550r/min adds the adhesive of 20-32 mass parts, that is, forms sediment after stirring 40-60min
5-7 parts of powder, 5-8 parts of polyvinyl alcohol, 5-6 parts of polyurethane, 1-3 parts of butyl rubber, 2-3 parts of vinyl acetate resin, waterborne organic silicon
2-5 parts of epoxy resin, at 40-50 DEG C of temperature, mixing speed 800-850r/min stirs 60-90min, obtains sticky dispersion
Liquid；
(4) foam cotton is dipped in the sticky dispersion liquid of step (3), is put into mold after adsorption saturation, cooling solidification, Gu
It is 3-5 DEG C to change temperature；
(5) the foamed aluminium cotton in mold is sintered 1-2h at 100-150 DEG C, 2-3h is sintered at 150-200 DEG C, in 200-300
DEG C sintering 2-3h, at 300-400 DEG C be sintered 2-3h, at 400-500 DEG C be sintered 1-2h, at 500-600 DEG C be sintered 1-2h, in 600-
800 DEG C of sintering 3-4h, after being sintered 1-2h at 800-850 DEG C, carry out natural cooling, after being cooled to room temperature, first use 40-50 mass
The absolute ethyl alcohol of part is washed, and is then used the ultra-pure water of 50-75 mass parts to be washed again, be can be obtained after washing
Foamed aluminium material；
(6) foamed aluminium material made from step (5) is glued respectively to the both side surface for the aluminium sheet ontology that thickness is 20-30mm
On, the thickness for the foamed aluminium material pasted in the both side surface of aluminium sheet ontology is 20-25mm.
