Description
Technical field
The present invention relates to environmental protection high speed highway, railway, light rail noise abatement field more particularly to a kind of utilization are solid
The acoustic barrier plate of body waste preparation.
Background technique
With the high speed development of China's infrastructure, people is given in a large amount of constructions of highway, high-speed railway, urban light rail
While bring convenience, traffic noise pollution problem is also got worse, and subjective reflection is deeply impacted, and it is normal to disturb resident
Work, studying and living.The governing problem of noise pollution has become social concern urgently to be resolved.At the same time, with work
Industry, urbanization process quickly propel, produce and live in generated solid waste it is also more and more, by solid waste
Environmental problem caused by object also than more prominent, how scientific and reasonable processing these solid waste, reduce the dirt to environment
The problem of contaminating, also becoming people's growing interest.
At present in a variety of control methods of traffic noise pollution, setting acoustic barrier is a kind of relatively effective side
Method.The resource utilization of solid waste simultaneously, is made into acoustic barrier plate, not only reduces the discharge of solid waste,
Noise pollution problem can also be effectively administered, certain business efficiency can also be generated by bringing while preferable environmental efficiency.
Currently, conventional acoustic shield plates generally use front and back plate, central filler sound-absorbing material, front plate is generally worn
Orifice plate, cooperation sound-absorbing material form sound absorption structure, and backplate is not perforated, used as sound insulationg board.The acoustic barrier plate is adopted mostly
Be made of metal material, have light-weight, the easy for installation and preferable advantage of sound-adsorbing sound-insulating hung effect, but due to its weatherability is poor,
The disadvantages of service life is short, sound reflection is big, cost performance is not high, was also gradually replaced by other materials in recent years.
In order to improve the weatherability and service life of acoustic barrier, cement base acoustic barrier can also be used.Chinese patent Shen
Please CN102852098A disclose a kind of cement base sawdust composite noise barrier, be mainly made of sawdust layer and concrete layer, benefit
With the cohesive force of cement clay, sawdust layer and concrete layer are bonded together, while using the hole of sawdust layer itself, being absorbed
The energy of sound carries out itself consumption, to achieve the purpose that noise reduction.Chinese patent CN204266138U discloses one kind by surpassing
Sound barrier made of high-performance powder concreting comprising more root posts and multiple between adjacent columns connect up and down
The wallboard connect, top wallboard are equipped with arc panel, and wallboard is that abatvoix is equipped among two pieces of soundproof plates.Using cement base sound
Although sound barrier good weatherability, low cost, manufacture craft mostly uses greatly traditional pouring molding method, generally existing surface density
It is high, intensity is weak, heaviness is coarse, unsightly, transportation cost height, the disadvantages of installation is difficult.
In order to improve absorbing sound and lowering noise performance, foamed material can also be used, by its unique foam structure, by air in hole
It rubs in gap with basis material, and because of the viscous effect of air and basis material, sound can be absorbed in the form of thermal energy.Though
So there are good sound absorption qualities, but the material fire protecting performance is poor, intensity is low, thus be gradually backed out use, or is only used as sound
Sound-absorbing core plate uses in shield plates.Chinese patent CN103147520A discloses a kind of modified fretting map body grain of abandoned mine ground-slag
The method that lightweight inhales sound insulation core plate is prepared, adds abandoned mine powder, in polyurethane foam material to improve the rigid of foaming body grain
Degree and density are prepared by compression molding to improve foam oise insulation factor and inhale sound insulation core plate.The preparation method is compression molding,
Production efficiency is not high, although addition abandoned mine powder increases the rigidity and density of material, but still cannot be as acoustic barrier
Plate uses, and is only capable of as sound-absorbing core material.
With the quickening of current modernization, the development in city, industrial prosperity, the processing and disposition of solid waste
Technology is mature already, and resource utilization also has involved in preparation field of compound material.Powder is made in solid waste
It is widely used in polymer composite as filler addition, but utilizes the acoustic barrier of solid waste preparation
Plate temporarily has not been reported.
