Abstract
The utility model relates to a special-shaped short fiber acoustic board, which comprises an acoustic board main body and a polyester fiber layer; the sound-absorbing board main body and the polyester fiber layer are fixedly connected in an adhesion mode; the polyester fiber layer is formed by weaving fibers; the surface of the fiber is irregular, and the interior of the fiber is of a porous structure; the utility model discloses utilize the anomalous surface of fibre, increase the reflection route of sound wave, make it consume the energy gradually, play the noise cancelling effect, the fibre is inside to be many empty structures simultaneously, plays lightweight effect when increasing the sound absorbing board thickness.
Description
Technical Field
The utility model relates to an acoustic panel technical field refers in particular to a dysmorphism short-staple acoustic panel.
Background
The fiber sound-absorbing board is an ideal sound-absorbing decorative material, has the characteristics of environmental protection, flame retardance, heat insulation, heat preservation, moisture resistance, mildew resistance, easy dust removal, easy cutting, mosaic, simple and convenient construction, high cost performance and the like, has multiple patterns and colors, and can meet the decoration requirements of different styles and levels; however, in order to seek a higher sound absorption effect, the conventional fiber sound absorption plate only needs to increase the thickness or the number of layers of the fiber sound absorption plate, so that the fiber sound absorption plate is heavy, is inconvenient to carry, and greatly increases the production cost.
SUMMERY OF THE UTILITY MODEL
The utility model discloses the purpose is in order to overcome prior art not enough and provide a special-shaped short-staple abatvoix, not only to inhale sound effectual, and can play lightweight effect.
In order to achieve the above purpose, the utility model adopts the technical scheme that: a special-shaped short fiber sound-absorbing board comprises a sound-absorbing board main body and a polyester fiber layer; the sound-absorbing board main body and the polyester fiber layer are fixedly connected in an adhesion mode; the polyester fiber layer is formed by weaving fibers; the surface of the fiber is irregular, and the interior of the fiber is of a porous structure.
Preferably, the thickness of the polyester fiber layer is 1-3 mm.
Preferably, the sound-absorbing plate main body is of a hollow structure.
Preferably, the sound absorption plate main body is filled with sound absorption cotton.
Preferably, the sound-absorbing panel main body and the polyester fiber layer are connected by an adhesive tape.
Preferably, the rough surface of the adhesive tape is fixedly connected with the polyester fiber layer through sewing, and the hook surface of the adhesive tape is fixedly connected with the sound-absorbing board main body through strong back glue.
Because of above-mentioned technical scheme's application, compared with the prior art, the utility model have the following advantage:
the utility model discloses utilize the anomalous surface of fibre, increase the reflection route of sound wave, make it consume the energy gradually, play the noise cancelling effect, the fibre is inside to be many empty structures simultaneously, plays lightweight effect when increasing the sound absorbing board thickness.
Drawings
The technical scheme of the utility model is further explained by combining the attached drawings as follows:
figure 1 is the sectional view of dysmorphism short-staple abatvoir of the utility model.
Wherein: 1. a polyester fiber layer; 2. sticking a tape; 3. a sound-absorbing panel main body; 4. silencing cotton.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Figure 1 is the special-shaped short fiber acoustic board of the utility model, which comprises an acoustic board main body 3 and a polyester fiber layer 1; the sound-absorbing board main body 3 and the polyester fiber layer 1 are fixedly connected in an adhesion mode; the polyester fiber layer 1 is formed by weaving fibers and has the thickness of 1-3 mm; the surface of the fiber is in an irregular shape, can be in a cross shape or a trilobal shape and the like, and the interior of the fiber is in a porous structure; the special design of the spinneret orifice of the spinneret plate is utilized, so that the cross section of the extruded fiber has an irregular shape, the surface area of the fiber is increased, the sound waves are reflected on the surface of the fiber until the energy of the fiber is exhausted, the noise reduction effect is achieved, meanwhile, the fiber is internally provided with a porous structure, the sound absorption effect is further enhanced in the sound wave inlet hole, and the light weight effect is achieved.
Further, the sound-absorbing board main body 3 is of a hollow structure, so that the overall weight of the special-shaped short fiber sound-absorbing board is reduced, and the sound-absorbing board is convenient to carry.
Further, the sound-absorbing board main body 3 is filled with the silencing cotton 4, so that the sound-absorbing effect can be further improved under the condition that the overall thickness of the special-shaped short-fiber sound-absorbing board is not increased.
Further, the sound-absorbing board main body 3 is connected with the polyester fiber layer 1 through the adhesive tape 2, so that the polyester fiber layer 1 can be conveniently taken down from the sound-absorbing board main body 3 for cleaning, and the cleaning is more convenient.
Further, the rough surface of the adhesive tape 2 is fixedly connected with the polyester fiber layer 1 through sewing, and the hook surface of the adhesive tape 2 is fixedly connected with the sound-absorbing board main body 3 through strong back glue.
The above is only a specific application example of the present invention, and does not constitute any limitation to the protection scope of the present invention. All the technical solutions formed by equivalent transformation or equivalent replacement fall within the protection scope of the present invention.
