Description
Technical field
The present invention relates to sound-absorbing sound insulation new material technology field, specially a kind of low-cost and high-performance sound-absorbing shield plates processing
Method.
Background technique
Noise barrier refers to the wall structure to completely cut off noise being arranged to mitigate ambient noise.Soundproof wall
Referred to as sound barrier.It is inserted into a facility between sound source and recipient, Acoustic Wave Propagation is made to have a significant additional attenuation, thus
The influence of noise in certain area where decrease recipient, such facility are known as sound barrier.Be divided into traffic noise barrier,
Equipment noise decays noise barrier, industrial factory's circle noise barrier, is most using all types of sound barriers on highway and highway
Place.Noise barrier initially takes plate sound insulation, since noise can be propagated around around sound barrier continuation, so, now
It is required that sound barrier surface is cellular porous structure, the soundproof effect of sound barrier is promoted by sound absorption function.At present extensively
Application is plastic foamboard and polyurethane foam board, and sound-absorbing soundproof effect is very good, but since anti-uv-ray is poor, cruelly
It is exposed at aerial degradable weathering, service life is not grown.The metal foamings new material such as foamed aluminium developed in recent years, sound-absorbing sound insulation effect
Fruit is more preferable, and anti-uv-ray is strong, even if exposure is also not easy corrosion and ageing in the sky, service life is very long, but its manufacturing cost
It is too high, it is difficult to promote and apply.
The progress of air entrained concrete technology is that the low sound-absorbing barrier of development cost brings opportunity.It is known that aerating coagulation
Soil is added and is sent out for primary raw material with siliceous material (sand, flyash and containing silicon tailings etc.) and calcareous material (lime, cement)
Gas agent (aluminium powder, SDS efficient aerating powder), is made up of technical process such as ingredient, stirring, casting, precuring, cutting, steam pressure, maintenances
Light porous silicate product.Because it contains a large amount of uniform and tiny stomatas, except have bulk density is light, thermal insulation property is high, every
Outside the good performance of audio fruit, anti-uv-ray is also very strong, even if exposure is also not easy corrosion and ageing, service life in the sky
Very long, manufacturing cost is low, but its foaming aperture is small, can only absorb high frequency noise, and after being cut into thin plate, the anti-energy that fractures
Power is greatly reduced.
Outside current top grade sound barrier does not require nothing more than sound insulation, sound-absorbing effect is had excellent performance, also require sound barrier that can prevent fires anti-
Ultraviolet light is anti-to fracture, and is not easy corrosion and ageing in the sky, durable, while manufacturing cost wants cheap.
Summary of the invention
The present invention provides a kind of fire prevention, sun-proof, lightweight, high-strength, inexpensive for technological deficiency existing for existing sound barrier
High-grade sound barrier plate processing technology.
A kind of low-cost and high-performance sound-absorbing shield plates processing method is to be mixed to mix larger grain in air entrained concrete
The polystyrene foam particles (EPS) of diameter, then successively paving in laminated pouring enhances grid screen, and formation alternates superposition
Stratiform module, last concordant dicing is to get low-cost and high-performance sound-absorbing barrier plate.
Further, eps foam particle is mixed in conventional air entrained concrete, is made containing EPS foam beads and aerating
The substrate of concrete, wherein the volume ratio of eps foam particle and air entrained concrete is 1:3-6；
Further, substrate casting is paved in a mold, forms bottom, one layer of enhancing is laid on the bottom
Grid screen, then in the one layer of substrate that pave on enhancing grid screen, and so on, it forms several layers substrate and enhancing grid screen is handed over
For the stratiform module of superposition；
Further, enhancing grid screen spacing is determined according to finished product plate thickness, it is desirable that every block of plate being cut into is at least interior
Containing 2 layers of enhancing grid screen.
Further, by layered module dicing, sound-absorbing barrier plate semi-finished product are obtained, (such as with kneader
Hairbrush, powered brush etc.) foam beads that plate surface is inlayed are ground off, increase plate face porosity, improves sound absorption qualities, finally load onto
Frame, resulting sound-absorbing barrier plate finished product are fixed convenient for assembling.
Further, the eps foam particle requirement partial size 1.5-4mm, not of uniform size, partial size 3mm little particle below
Account for 30% or so, the bulky grain of partial size 3mm or more accounts for 70% or so.
Further, described enhancing grid screen distance 2cm or so, the material for enhancing grid screen can use wire or change
The fibrages networking such as, plant, glass, fiber thickness are determined according to fibre strength, by the muscles and bones for enhancing grid screen
Structure promotes the anti-performance that fractures of air entrained concrete sound barrier plate, does convenient for sound barrier sheet side product big.
Further, the powder ground off is crumpled on the sawdust cut down and surface, should all be recycled investment and be mixed next time
Solidifying soil recycles in mixing and stirring, it is ensured that clean and environmental protection production.
Compared with prior art, the beneficial effects of the present invention are:
1, sound-absorbing barrier plate prepared by the present invention foams and adds big partial size foam due to using concrete simultaneously
Grain technique, not only lightweight, fire prevention, soundproof effect are good, but also since plate surface porosity is high, aperture multiplicity, are conducive to absorb
The noise of various frequencies, so sound absorption qualities are excellent.
2, this sound barrier plate combines enhancing grid screen muscles and bones structure by substrate of concrete, not only intensity height, anti-folding
Performance is good, durable, and can support ultraviolet radiation resisting, is not afraid of and exposes to wind and rain, the not degradable aging under solar exposure.
3, most prominent feature is that manufacturing cost is cheap.It is particularly suitable for high speed, high-speed rail both sides sound-absorbing barrier and indoor fire safety
Sound-absorbing finishing, has a extensive future.
