Abstract
The utility model relates to a cement composite plate capable of adsorbing and insulating sound, which is formed by overlaying and fixing high-strength cement extrusion plates and cement base pearlite sound adsorption plates. The cement composite plate is simple in structure, light in weight, low in production cost, good in sound insulation and adsorption effects and long in service life.
Description
Technical field
The utility model relates to a kind of sound barrier, relates in particular to a kind of cement sound absorption composite plate.
Background technology
Along with China's urban road develop rapidly, automobile noise pollutes and is on the rise, and therefore its improvement work has been caused people's attention.At present; The effective means that reduces that automobile noise pollutes is that sound barrier is set in the road both sides; Existing sound barrier is filled out damping material and is constituted for the surface has mostly in the metal material of porous, fiber sound materials such as the inner filling glass cotton of this sound barrier are with the absorption low frequency noise; But because the perishable variable color of metal material, antiseptic property is poor, heavy, and cost is high, so the use of this kind sound barrier is limited.
Summary of the invention
The utility model technical problem to be solved provides a kind of cement sound absorption composite plate, and the utility model is simple in structure, and is in light weight, and cost of production is low, and sound absorption is effective, long service life.
For solving the problems of the technologies described above, the utility model adopts following technical proposals: a kind of cement sound absorption composite plate, it is by the high-strength cement extrusion board and cement based perlite acoustical board is stacked fixedly constitutes.
Be provided with inorganic adhesive between said high-strength cement extrusion board and the cement based perlite acoustical board.
Said cement based perlite acoustical board embeds on the high-strength cement extrusion board, and both bonding surfaces apply and are bonded with inorganic adhesive.
Said cement sound absorption composite plate is to be made up of the surperficial cement injection base perlite sound absorption sizing material forming at the high-strength cement extrusion board that is coated with inorganic adhesive.
Said inorganic adhesive is silicates bonding agent, Sulfates bonding agent, phosphoric acid salt bonding agent or borate family bonding agent.
Said cement based perlite acoustical board surface is provided with the sound absorption perforation, and its aperture is 0.2～0.6mm, and perforated percentage is 20～30%.
The cross section of said high-strength cement extrusion board is side " recessed " font groove shape body; These groove shape body two lateral wall correspondences are provided with the assembling falcon groove of coupling; Said groove shape body diapire is provided with at least two parallel perforation through holes, and said the perforation in twos constitutes reinforcing rib between the through hole.
Said cement based perlite acoustical board external surface is provided with the groove-like reinforcing rib.
A kind of beneficial effect of cement sound absorption composite plate is:
1, compound sound barrier has high strength, high compact, high impact resistance, and sound insulation factor is 40 decibels;
2, the compound acoustical board that uses is the cement based pearlite slab, and integral body is installed with the sound absorption air-vent, and the sound absorption reduction coefficient is between 0.75～0.9;
3, the compound sound insulationg board scope of application is wide, applicable to indoor, exterior decoration, and through street, light rail, high ferro, subway, culvert, field of traffic and various industry such as tunnel, factory building, workshop and theater, the environmental protection noise abatement in fields such as residential quarters;
4, simple installation is not restricted by weather;
5, have weatherability, anti-moist, weather proof, acid and alkali-resistance corrodes, long service life;
6, cost is low.
The utility model is simple in structure, and is in light weight, and cost of production is low, and sound absorption is effective, long service life.
