Abstract
The utility model provides an it is thermal -insulated cotton that sound is inhaled to car, including inhaling the cotton body of sound, inhale the cotton body of sound including melt spout cotton layer and be located respectively melt spout cotton layer about the last non -woven fabrics layer and lower non -woven fabrics layer on two sides, its characterized in that: melting and spouting cotton layer and melted to spout by pp and pet material mixture and form, go up non -woven fabrics layer top and below and be provided with the bamboo charcoal adsorbed layer respectively, the cross -section of bamboo charcoal adsorbed layer is honeycomb, and the below on lower non -woven fabrics layer is provided with aluminium foil heat preservation and non -setting adhesive respectively, should inhale the sound cotton and have better noise cancelling effect, has the stability of long -term amortization.
Description
Technical field
The utility model relates to a kind of acoustical cotton, more particularly, relates to a kind of automobile acoustical absorption cotton.
Background technology
Along with scientific and technological fast development, automobile more and more becomes the indispensable vehicles, and use is frequent and general in the extreme,And the material of the absorptive product of automotive interior, mainly taking waste woven felt as main, is the raw material machinery taking cotton as master with waste and old recovery at presentProcess. Its shortcoming is that weight is large, smell is large, volatile organic matter composition is higher, and product easily burns, sound-absorbing effectRate is also very low, and this causes in the time of running car, and influence of noise is very serious, and comfortableness and the security of driving are also very low. ExistingHave in technology and adopted melt-blown cotton layer structure, this melt-blown cotton layer mixes melt-blown forming by pp and pet material, and melt-blown cotton layer is by nothingSpin cloth and wrap up sizing, but due to the use of permanent time of process of nonwoven, its durability and intensity can variation, finalParcel to melt-blown cotton layer can lose efficacy.
Utility model content
Based on the problems referred to above, the utility model object is to provide a kind of automobile acoustical absorption cotton, and this acoustical cotton has good noise reduction effectReally, there is the stability of long-term noise reduction.
For above problem, provide following technical scheme: a kind of automobile acoustical absorption cotton, comprises acoustical cotton body, acoustical cotton bodyComprise melt-blown cotton layer and lay respectively at upper nonwoven layer and the lower nonwoven layer of melt-blown cotton layer upper and lower surface, it is characterized in that: melt-blownCotton layer mixes melt-blown forming by pp and pet material, and upper nonwoven layer top and below are respectively arranged with bamboo Charcoal Adsorption layer, and bamboo charcoal is inhaledThe cross section of attached layer is honeycomb, and the below of lower nonwoven layer is respectively arranged with foil insulation and adhesive sticker.
The beneficial effects of the utility model: the setting of bamboo Charcoal Adsorption layer has suction-operated, can protect upper nonwoven layer,Prevent its mouldy and moth, prevent that melt-blown cotton layer from producing mouldy, there is higher stability, simultaneously the bamboo Charcoal Adsorption of honeycombLayer can further improve erasure effect, and double-deck bamboo Charcoal Adsorption layer contributes to the protection to upper nonwoven layer and further carriesThe erasure effect of high silencing cotton, the setting of foil insulation can realize the insulation of acoustical cotton, has better heat insulation effect.
Brief description of the drawings
Fig. 1 is the structural representation of the cotton cutaway view of automobile acoustical absorption in the utility model embodiment.
The melt-blown cotton layer of number in the figure implication: 1-; 2-bamboo Charcoal Adsorption layer; The upper nonwoven layer of 3-; 4-bamboo Charcoal Adsorption layer; Nonwoven under 5-Layer of cloth; 6-the second foil insulation; 7-non-drying glue layer.
Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in further detail. Following examplesBe used for illustrating the utility model, but be not used for limiting scope of the present utility model.
As shown in Figure 1, a kind of automobile acoustical absorption cotton, comprises acoustical cotton body, and acoustical cotton body comprises melt-blown cotton layer 1 and difference positionIn upper nonwoven layer 3 and the lower nonwoven layer 5 of melt-blown cotton layer 1 upper and lower surface, melt-blown cotton layer 1 mixes molten by pp and pet materialSpray forms, and upper nonwoven layer 3 tops and below are respectively arranged with bamboo Charcoal Adsorption layer 4, bamboo Charcoal Adsorption layer 2, bamboo Charcoal Adsorption layer 4,2 cross section is honeycomb, and the below of lower nonwoven layer 5 is respectively arranged with foil insulation 6 and adhesive sticker 7. Bamboo Charcoal Adsorption layerSetting there is suction-operated, can protect upper nonwoven layer 3, prevent its mouldy and moth, prevent melt-blown cotton layer 1Produce mouldyly, make it have longer durability and stability, the bamboo Charcoal Adsorption layer of honeycomb can further improve and disappear simultaneouslyAudio fruit, double-deck bamboo Charcoal Adsorption layer contributes to the protection to upper nonwoven layer 3 and further improves the noise reduction effect of silencing cottonReally, the setting of foil insulation 6 can realize the insulation of acoustical cotton, has better heat insulation effect.
The above is only preferred embodiment of the present utility model, it should be pointed out that for those skilled in the art, not departing under the prerequisite of the utility model know-why, can also make some improvement and modification, this of above-mentioned hypothesisA little improvement and modification also should be considered as protection domain of the present utility model.
