Description
Technical field
The invention belongs to building material technical fields, and in particular to a kind of microparticle noise reducing plate.
Background technique
According to the material of sound absorption screen board, sound barrier is broadly divided into metal sound barrier and nonmetal concrete sound barrier two is big
Class.In terms of sound barrier service condition, metal sound barrier can cause to destroy because of fatigue.Such as France, Japan's high-speed rail technology hair
Exhibition is national earlier, mainly uses metal sound barrier in the past, and most of to have been replaced because of fatigue rupture, high-speed railway is flourishing
Germany generally use nonmetal concrete sound barrier, this kind of structure type durability is good and firm, can be literary according to local nationality
Change creation into various artistic structures, builds and maintenance cost is low, have biggish advantage compared to metal sound barrier.
But existing sound barrier either metal sound barrier or non-metal sound barrier, main sound absorption function are all from
It is routinely mineral wool in the sound-absorbing material filled in sound absorption screen board.Dampness or fiber easily occur in long-term use for mineral wool
Change, mineral wool dampness tenesmus agglomeration influences sound absorbing performance, the dust and microfibre formed after mineral wool aging disperses, can be to big
Compression ring border pollutes.
Summary of the invention
Goal of the invention: exist in the prior art the sound-absorbing material service life it is short, not environmentally aiming at the problem that, the purpose of the present invention exists
In providing a kind of microparticle noise reducing plate.
Technical solution: to solve the above-mentioned problems, the technical solution adopted in the present invention is as follows:
A kind of microparticle noise reducing plate, is made of sandstone particle and inorganic adhesive；The sandstone particle and inorganic adhesive
Weight ratio be 3: (0.8~1)；
The sandstone particle is the quartz sand that single-stage is matched, and inorganic adhesive is made of cement, reinforcing agent, additive and water；
The cement is portland cement, ordinary portland cement or white portland cement, and reinforcing agent is by microballon, silicon
Ash, sodium sulphate and gypsum are made, and additive is high performance water reducing agent of polyocarboxy acid.
Preferably, two layers of basalt grid cloth is equipped with inside the noise reducing plate.
Preferably, the inorganic adhesive each component mass ratio is respectively cement 65%~75%, reinforcing agent 6%~8%,
Additive 0.12%~0.16%, water 18%~30%.
Preferably, strength grade >=52.5 grade of the portland cement.
Preferably, the mass ratio of the reinforcing agent each component is respectively microballon 50%~60%, silicon ash 30%~42%, sulphur
Sour sodium 2.5%~3.0%, gypsum 5%~8%.
Preferably, the partial size for the quartz sand that the single-stage is matched is 0.63~1.18mm or 1.18~2.36mm.
Preferably, the quartz sand is that solid color forms or multiple color collocation forms, and improves decorative effect.
Preferably, water-reducing rate >=30% of the high performance water reducing agent of polyocarboxy acid.
The utility model has the advantages that compared with prior art, the invention has the advantages that
(1) present invention can replace traditional fibre sound absorption cotton completely, and not need cover, effectively prevent cellucotton aging
The dust and microfibre formed afterwards disperses, and pollutes to atmospheric environment.
(2) present invention is mixed with sandstone with single-stage by cement inorganic coagulation material and is bonded together, and is formed with mutual
The microvoid of perforation, makes noise reducing plate form different flow resistances and sound absorption characteristics.
(3) noise reducing plate of the invention has good sound absorbing performance and sound insulation property simultaneously.
(4) fire protecting performance of the present invention reaches the A grade of GB8624-2012, high, weather-proof, moisture-proof, the anti-wind pressure of intensity, in environment
In the case where extremely severe, noise reducing plate can also work for a long time, acoustic absorptivity and oise insulation factor variation less so that noise reduction
The service life of plate extends.
(5) present invention has many advantages, such as that convenient environmental protection, materials, color multiplicity, decorative effect are strong, cheap.
