Abstract
The utility model relates to a noise reduction type car roof interior trim part. The noise reduction type car roof interior trim part is characterized by comprises an interior trim part body (1). An inner structure of the interior trim part body (1) from the up and down is formed by a precoat layer (1.1), an upper glass fiber layer (1.2), an upper glue-water layer (1.3), a polyurethane foam layer (1.4), a lower glue-water layer (1.5), a lower glass fiber layer (1.6) and a non-woven fabric layer (1.7). According to the noise reduction type car roof interior trim part, a layer structure is improved and the polyurethane foam layer which is provided with a high sound absorption effect can be added in the noise reduction type car roof interior trim part to improve a noise reduction performance of the interior trim part. Meanwhile, noise which enters into the car can be reduced effectively.
Description
Technical field
The utility model relates to a kind of noise reducing type roof interior trimming parts, is loaded on the roof in the manned vehicle, belongs to the automobile decoration piece technical field.
Background technology
Manned vehicle inside all is equipped with interior trimming parts and is beautified interior space, yet the roof interior trimming parts not only requires to have effect attractive in appearance, and the function of certain sqouynd absorption lowering noise also must be arranged.In the past passenger car top interior trimming parts is inner because laminar texture is simple, and its sound-absorbing material layer preferably not, causes the decrease of noise functions of interior trimming parts not high, also makes the anti-acoustic capability in the car relatively poor.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and providing a kind of can effectively absorb sound, and reduces the noise reducing type roof interior trimming parts that noise enters.
The purpose of this utility model is achieved in that
The utility model noise reducing type roof interior trimming parts, comprise the interior trimming parts body, the inner structure of described interior trimming parts body is comprised of precoat, upper glass fibrage, upper glue layer, polyurethane foam, lower glue layer, lower-glass fibrage, nonwoven layer respectively from top to bottom.
The utility model noise reducing type roof interior trimming parts has the following advantages:
The improvement of the utility model noise reducing type roof interior trimming parts by its laminar texture, and add therein the polyurethane foam that one deck has high sound-absorbing effect, thus improved the decrease of noise functions of interior trimming parts, and can effective noise reduction function into the car.
Description of drawings
Fig. 1 is the structural representation of the utility model noise reducing type roof interior trimming parts.
Fig. 2 is the laminar texture scheme drawing of interior trimming parts body among Fig. 1.
Among the figure: interior trimming parts body 1, precoat 1.1, upper glass fibrage 1.2, upper glue layer 1.3, polyurethane foam 1.4, lower glue layer 1.5, lower-glass fibrage 1.6, nonwoven layer 1.7.
The specific embodiment
Referring to Fig. 1 and Fig. 2, the utility model relates to a kind of noise reducing type roof interior trimming parts, comprise interior trimming parts body 1, the inner structure of described interior trimming parts body 1 is comprised of precoat 1.1, upper glass fibrage 1.2, upper glue layer 1.3, polyurethane foam 1.4, lower glue layer 1.5, lower-glass fibrage 1.6, nonwoven layer 1.7 respectively from top to bottom.
This noise reducing type roof interior trimming parts has the polyurethane foam 1.4 of high sound-absorbing effect by adding one deck in its laminar texture, thereby has improved the decrease of noise functions of interior trimming parts, and can effective noise reduction function into the car.
