Abstract
The utility model discloses a compound sound-absorbing film, comprising a base layer, wherein the base layer is a glass fiber cloth layer or a polyester fiber cloth layer; the base layer is provided with a plurality of pressing sticking layers; and one layer of a polytetrafluoroethylene layer respectively covers on and under the base layer. The compound sound-absorbing film disclosed by the utility model has the advantages of strong sound-absorbing capability, simple structure and convenience for realization.
Description
Technical field
The utility model relates to a kind of film material, is specifically related to a kind of absorptive membrane material.
Background technology
Since last century, the fifties began to occur in the world, the application of film material obtained develop rapidly to the membrane structure building as the construction style that breaks fresh ground.Along with development of city, the viaduct, city is more and more, and its anti-noise ability of building is had increasingly high requirement.
Absorbing sound and lowering noise is after sound wave gets into sound-absorbing material, and sound-absorbing material receives acoustic vibration, is converted into the heat energy of sound-absorbing material to the energy of sound wave, propagates thereby limit sound wave.
The utility model content
The technical problem that the utility model will solve is to provide a kind of sound absorbing power high membrane structure.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of composite sound-absorbing film comprises basic unit; Said basic unit is glass fibre layer of cloth or polyester fiber layer of cloth, and basic unit is provided with the sticking portion of some pressures, the upper and lower one deck polytetrafluoroethylene floor that respectively is coated with of basic unit.The staggered loose structure of fiber can be used for sound-absorbing in glass fibre layer of cloth or the polyester fiber layer of cloth, is provided with to press sticking portion to make deformation of fibers, has high sound-absorbing effect.
Further technical scheme is that the surface of polytetrafluoroethylene floor is provided with some holes line.Such structure makes the rough surface of whole composite sound-absorbing film, improves sound-absorbing effect.
The composite sound-absorbing film sound absorbing power of the utility model is strong, simple in structure, the convenient realization.
Description of drawings
Fig. 1 is the structural representation of the utility model composite sound-absorbing film.
Wherein, 1, glass fibre layer of cloth; 2, press sticking portion; 3, polytetrafluoroethylene floor; 4, hole line.
The specific embodiment
As shown in Figure 1, the composite sound-absorbing film of the utility model comprises basic unit; Said basic unit is a glass fibre layer of cloth 1, utilizes the staggered loose structure that forms of fiber to carry out sound-absorbing, and glass fibre layer of cloth 1 is provided with the sticking portion 2 of some pressures; Increase the deformation of glass fibre layer of cloth 1, promote sound-absorbing effect.The glass fibre layer of cloth 1 upper and lower one deck polytetrafluoroethylene floor 3 that respectively is coated with.The surface of polytetrafluoroethylene floor 3 is provided with some holes line 4, makes whole composite sound-absorbing film rough surface, further improves sound-absorbing effect.Basic unit can also use the polyester fiber layer of cloth to replace.
To one skilled in the art, can make other various corresponding changes and deformation, and these all changes and deformation should belong within the protection domain of the utility model claim all according to the technical scheme and the design of above description.
Claims (2)
1. a composite sound-absorbing film comprises basic unit, it is characterized in that: said basic unit is glass fibre layer of cloth or polyester fiber layer of cloth, and basic unit is provided with the sticking portion of some pressures, the upper and lower one deck polytetrafluoroethylene floor that respectively is coated with of basic unit.
2. composite sound-absorbing film according to claim 1 is characterized in that: the surface of polytetrafluoroethylene floor is provided with some holes line.
