Abstract
The utility model provides front wall sound-isolation pad, and sound insulating pad forms by five layer materials are compound, and wherein ground floor is nonwoven layer, and the second layer is the cotton layer of PE/PP blended fiber, and the 3rd layer is the cotton layer of polyster fibre, and the 4th layer is glass layer, and layer 5 is nonwoven layer.The utility model utilizes PP, it is little that the cotton layer of PE blended fiber has good combined filament layer density, material structure is harder and closely knit, can play the effect of good sound insulation and noise reduction and comparatively environmental protection, polyster fibre cotton has strong heat insulation, the effect of sound-absorbing, glass fibre has the stronger good sound-absorbing that has, damping, withstanding corrosion, insulation, high temperature resistant, fire-retardant performance, nonwoven fabrics has fire-retardant, sound-absorbing, noise reduction environmental protection characteristic, by by five layers by can the noise of automobile front wall being dropped to lower after preheating gluing cold isostatic compaction, can also effectively reach sound insulation, sound-absorbing, the effect of heat insulation and damping, meet the RoHS of European Union environment-protecting asepsis standard and the authentication of CCC China Compulsory.
Description
Technical field
The utility model relates to automotive trim field, is specifically related to a kind of automobile front wall sound-isolation pad.
Background technology
Automobile front wall sound-isolation pad, is arranged at automobile predecessor, plays the effect of sound insulation, and good material is made generally need to use soundproof effect.The exploration in automotive trim market, material category that at present sound insulating pad is used is various, dragons and fishes jumbled together, once and the sound insulation data that device is improved quality low usually can be buried disaster hidden-trouble and also can produce certain injury to human body simultaneously.
Now, China is electric, the production of electronic machine interior trim parts, all require to reach the RoHS of European Union environment-protecting asepsis standard and the authentication of CCC China Compulsory, and requirement has good soundproof effect, require interior products to there is lower smell, the objectionable impurities compositions such as formaldehyde still less, there is better anti-noise soundproof effect simultaneously.
Utility model content
For above problems of the prior art, the utility model provides the front wall sound-isolation pad that a kind of soundproof effect is good.
The utility model is achieved through the following technical solutions:
Front wall sound-isolation pad, described sound insulating pad forms by five layer materials are compound, and wherein ground floor is nonwoven layer, and the second layer is the cotton layer of PE/PP blended fiber, and the 3rd layer is the cotton layer of polyster fibre, and the 4th layer is glass layer, and layer 5 is nonwoven layer.
In described nonwoven layer, the cotton layer of PE/PP blended fiber, the cotton layer of polyster fibre, glass layer, nonwoven layer, position, every two-layer gap scribbles the glue-line of 1 millimeter of-3 millimeters of thickness, preheating cold press moulding after described nonwoven layer, the cotton layer of PE/PP blended fiber, the cotton layer of polyster fibre, glass layer, nonwoven layer gluing.
For making the utility model reach the effect of marketing, the material adopting all can be buied by market.Wherein PP is poly-mer polypropylene, and PE is polyethylene.
The beneficial effects of the utility model are: utilize PP, it is little that the cotton layer of PE blended fiber has good combined filament layer density, be conducive to the lightweight of car load, after mold pressing, material structure is harder and closely knit, can play the effect of good sound insulation and noise reduction and comparatively environmental protection, polyster fibre cotton has strong heat insulation, the effect of sound-absorbing, glass fibre has the stronger good sound-absorbing that has, damping, withstanding corrosion, insulation, high temperature resistant, fire-retardant performance, nonwoven fabrics has fire-retardant, sound-absorbing, noise reduction environmental protection characteristic, by by five layers by can the noise of automobile front wall being dropped to lower after preheating gluing cold isostatic compaction, can also effectively reach sound insulation, sound-absorbing, the effect of heat insulation and damping.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1 is nonwoven layer; 2 is the cotton layer of PE/PP blended fiber; 3 is the cotton layer of polyster fibre; 4 is glass layer.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further details.
The utility model provides a kind of automobile front wall sound-isolation pad, as shown in Figure 1, wherein sound insulating pad forms by five layer materials are compound, wherein ground floor is nonwoven layer 1, the second layer is the cotton layer 2 of PE/PP blended fiber, the 3rd layer is that 3, the four layers, the cotton layer of polyster fibre is glass layer 4, and layer 5 is nonwoven layer 1; Wherein in the cotton layer 2 of nonwoven layer 1, PE/PP blended fiber, the cotton layer 3 of polyster fibre, glass layer 4, nonwoven layer 1, position, every two-layer gap scribbles the glue-line of 1 millimeter of-3 millimeters of thickness, wherein preheating cold press moulding after nonwoven layer 1, the cotton layer 2 of PE/PP blended fiber, the cotton layer 3 of polyster fibre, glass layer 4 and nonwoven layer 1 gluing, the thickness of its mesoglea is unsuitable blocked up, if blocked up, easily cause sound insulating pad hard, impact is installed, glue-line is difficult for the bonding effect of thinner out of reach, adopts 1 millimeter-3 millimeters to be best.
For making the utility model reach the effect of marketing, the material adopting all can be buied by market.Wherein PP is poly-mer polypropylene, and PE is polyethylene.
The utility model utilizes PP, it is little that the cotton layer of PE blended fiber has good combined filament layer density, be conducive to the lightweight of car load, after mold pressing, material structure is harder and closely knit, can play the effect of good sound insulation and noise reduction and comparatively environmental protection, polyster fibre cotton has strong heat insulation, the effect of sound-absorbing, glass fibre has the stronger good sound-absorbing that has, damping, withstanding corrosion, insulation, high temperature resistant, fire-retardant performance, nonwoven fabrics has fire-retardant, sound-absorbing, noise reduction environmental protection characteristic, by by five layers by can the noise of automobile front wall being dropped to lower after preheating gluing cold isostatic compaction, can also effectively reach sound insulation, sound-absorbing, the effect of heat insulation and damping, meet the RoHS of European Union environment-protecting asepsis standard and the authentication of CCC China Compulsory, be worth of widely use.
