Along with popularizing of apartment and flats, people are adjacent and occupy, and the wall of shared limited thickness and floor make the noise problem of apartment floor become one of social focus problem.
At present, the constructional materials in apartment mainly adopts steel concrete or concrete-steel.But the wall of concrete structure or the quality on floor are thinner, are easy to propagate noise.
The lasting noise that send the noise of floor gap and automobile, aircraft or building site is different, and it is intermittent, and is bigger to the shake-up of health though noise figure is little, and the people is had the fidgets.This noise under the comprehensive function of sound wave, media vibrations and electric wave etc., from propagating into downstairs, brings a lot of worries for resident's life upstairs.
For solving the noise problem of floor gap, the technology of foamed material or synthetic fibers such as foamed polystyrene, mineral wool, glass wool or resin has appearred inserting or pasting in concrete.But, though the most of material in the above-mentioned technology has heat-insulating capability preferably, all belong to inflammable substance, therefore,, nor can fully reduce noise not only bad for security against fire.
In order to solve the existing problem of above-mentioned noise and heat-barrier material, modern apartment generally adopts so-called floating floor structure, promptly above the concrete ground flaggy bumper post is set, and establishes heat insulation padded coaming and cellular concrete in addition thereon, simultaneously, flaggy and in abutting connection with metope discretely.
But above-mentioned floating floor structure, it constructs complicated, and the floor easily produces be full of cracks, particularly can not fully absorb impact and the vibrations that put on the floor after the construction, thereby exists anti-be full of cracks and vibration resistance sexuality poor, the problems such as noise that can not fully absorb the upper strata and taken place.
As another kind of light thermal-insulating heat-barrier material, with the expand expanded polystyrene (EPS) (EPS of its structure of chemical mode, Expanded polystyrene) and with the expand expanded polypropylene (EPP, Expanded Polypropylene) of its structure of physics mode also be used as the noise reduction of floor gap, heat insulation and buffering material.
Though above-mentioned EPS or EPP material all have certain superiority at aspects such as weight, intensity and heat stabilitys, degenerate easily when running into chemicals, easily cause environment pollution, thereby its use are very limited.
The another method that solves the floor gap noise problem at present is surperficial buffer method.The principle that described surperficial buffer method adopted is to change the vibroseis characteristic that puts on the floor.For example, lay the soft final material in floor such as carpet, foamed plastics series material or oily a heatable brick bed paper, make the elasticity of the final material use in these floors self absorb suffered vibrations at floor surface.Final material absorbs suffered vibrations, can prolong the attack time, even Zong shock momentum does not change, also can slow down maximum shaking force, thereby reduces the vibrations sound.
Though above-mentioned surperficial vibratory absorption process can reduce high frequency noise to a great extent, for low frequency noise, as fall the effect that the weight vibrations sound that produces etc. does not then have reduction on the ground with foot-operated ground, weight.
For another example, automobile, bullet train or road guard rail haulage devices such as (guard rail) perhaps is equiped with buffer, but perhaps building service design is become the structure of absorbing vibration.
But these buffers are most of to need to install the high price equipment that utilizes oil pressure etc., though and when its structure of change, can absorb disposable vibrations, can't resolve the problem that absorbs other physics aspects such as noise.
Therefore, need a kind of buffering, damping, noise reduction composite material that is applicable to each technical field such as building, building, machinery of exploitation, promptly possess the noise function and the heat insulating function that can reduce the building floor gap simultaneously, and can guarantee the stability, buffering of haulage device and the sandwich of complex function such as shockproof.
