Abstract

The invention discloses a silencing composite board used for an automobile. The silencing composite board comprises a sound insulation substrate, a sound absorption layer and a sound absorption panel layer are sequentially arranged on the surface of the sound insulation substrate from bottom to top, the surface of the sound absorption panel layer is coated with a fire-proof coating, the top face of the sound absorption layer is in a concave-convex saw tooth shape, and an adhesive coating is arranged on the bottom face of the sound insulation substrate. The silencing composite board is installed in an assembly gap of the automobile and has a good sound absorption and noise reduction effect; particularly, the top face of the sound absorption layer is in the concave-convex saw tooth shape, in this way, the sound absorption area of the sound absorption layer can be greatly increased, and the noise reduction effect is improved; meanwhile, the surface of the sound absorption panel layer is coated with the fire-proof coating, so that safety performance is improved; in addition, the adhesive coating is arranged on the bottom face of the sound insulation substrate, in this way, the silencing composite board can directly adhere to the automobile as long as a packaging film of the silencing composite board is disclosed, and installing is convenient.

Description

Automobile noise reduction composite panel
Technical field
The present invention relates to technical field of automobile, especially, relate to a kind of automobile noise reduction composite panel.
Background technology
Along with growth in the living standard, automobile enters huge numbers of families as the very common vehicle of one, and because domestic population base is huge, the recoverable amount of family car is also very huge.Meanwhile, along with the development of technology, customer it is also proposed higher requirement for the comfort property of family car.Automobile operationally, can produce various noise, the sound of such as engine running, and the tire that tire and ground friction produce is made an uproar, long-duration driving, and these noises can have a strong impact on the traveling comfort of navigating mate and passenger.Thus, how reducing noise that automotive operation produces is an industry difficult problem urgently to be resolved hurrily.
Summary of the invention
The object of the invention is to provide a kind of automobile noise reduction composite panel, and to solve in prior art, the noise difficulty of automotive operation reduces, and affects the problem of car comfort energy.
For achieving the above object, the invention provides a kind of automobile noise reduction composite panel, comprise: sound insulation substrate, the surface of described sound insulation substrate to lower and on be disposed with sound absorbing layer, Suond-absorbing panel layer, the surface coating of described Suond-absorbing panel layer has fire protection coating, the end face of described sound absorbing layer is concavo-convex zigzag fashion, and the bottom surface of described sound insulation substrate is provided with adhesive coating.
Further, described sound absorbing layer is poly-ester fibres acoustical cotton.
Further, described Suond-absorbing panel layer is polyester fibre acoustic panel.
Further, described sound insulation substrate is deadening felt.
The present invention has following beneficial effect:
This noise reduction composite panel is installed in the assembling gap of automobile, there is good absorbing sound and lowering noise effect, especially the concavo-convex zigzag fashion of sound absorbing layer end face, greatly can improve the sound-absorbing area of sound absorbing layer, improve noise reduction; Meanwhile, the surface coating of Suond-absorbing panel layer has fire protection coating, improves safety performance; In addition, the bottom surface of sound insulation substrate is provided with adhesive coating, opens the packaging film of this noise reduction composite panel, can directly bond on automobile, easy for installation.
Accompanying drawing explanation
Below with reference to figure, the present invention is further detailed explanation.The accompanying drawing forming a application's part is used to provide a further understanding of the present invention, and schematic description and description of the present invention, for explaining the present invention, does not form inappropriate limitation of the present invention.In the accompanying drawings:
