Abstract
The utility model provides an it is thermal -insulated cotton that sound is inhaled to high efficiency, including inhaling the cotton body of sound, its characterized in that: inhale the cotton body of sound include first melt spout cotton layer and be located its respectively about the last non -woven fabrics layer and non -woven fabrics layer down on two sides, go up the non -woven fabrics layer, down the non -woven fabrics layer respectively and first melt to spout be provided with the second between the cotton layer and melt and spout cotton layer, the second melt and spout melting of cotton layer and spout density and be greater than first melting and spout cotton layer and set up, go up non -woven fabrics layer top and be provided with the bamboo charcoal adsorbed layer, the cross -section of bamboo charcoal adsorbed layer be honeycomb, the below on lower non -woven fabrics layer is provided with aluminium foil heat preservation and non -dry adhesive layer respectively, should inhale the sound cotton and have better noise cancelling effect, can carry out the multilayer elimination to the noise, has the stability of long -term amortization.
Description
Technical field
This utility model relates to a kind of acoustical cotton, more particularly, it relates to a kind of high-efficiency sound-absorbing heat insulation foam.
Background technology
Fast development along with science and technology, automobile increasingly becomes the indispensable vehicles, use in the extreme frequently with universal, and the material of the absorptive product of automotive interior is mainly based on waste woven felt at present, is to form by the raw material machining based on cotton of waste and old recovery.Its shortcoming is that weight is big, abnormal smells from the patient big, Volatile Organic Components is higher, and product easily burns, and sound-absorbing efficiency is the lowest, and this causes when running car, and influence of noise is very serious, and comfortableness and the safety driven are the lowest.Prior art have employed melt-blown cotton Rotating fields, this melt-blown cotton layer is formed by pp and pet material mixing is melt-blown, and melt-blown cotton layer is carried out parcel sizing by non-woven fabrics, but due to the use through the permanent time of non-woven fabrics, its durability and intensity can be deteriorated, and finally can lose efficacy the parcel of melt-blown cotton layer.
Utility model content
Based on the problems referred to above, this utility model purpose is to provide a kind of high-efficiency sound-absorbing heat insulation foam, and this acoustical cotton has preferable erasure effect, it is possible to noise is carried out multilamellar elimination, has the stability of long-term noise reduction.
For problem above, provide following technical scheme: a kind of high-efficiency sound-absorbing heat insulation foam, including acoustical cotton body, it is characterized in that: acoustical cotton body includes the first melt-blown cotton layer and lays respectively at the upper nonwoven layer of its upper and lower surface and lower nonwoven layer, upper nonwoven layer, lower nonwoven layer respectively and is provided with the second melt-blown cotton layer and the 3rd melt-blown cotton layer between the first melt-blown cotton layer, the melt-blown density cotton layer melt-blown more than first of the second described melt-blown cotton layer and the 3rd melt-blown cotton layer is arranged, upper nonwoven layer is provided above bamboo Charcoal Adsorption layer, the cross section of bamboo Charcoal Adsorption layer is honeycomb texture, lower nonwoven layer be respectively arranged below foil insulation and non-drying glue layer.
This utility model is further arranged to, and described the first melt-blown cotton layer, the second melt-blown cotton layer and the 3rd melt-blown cotton layer are formed by pp and pet material mixing is melt-blown.
The beneficial effects of the utility model: the setting of bamboo Charcoal Adsorption layer has adsorption, upper nonwoven layer can be protected, prevent it mouldy and moth, prevent melt-blown cotton layer from producing mouldy, there is higher stability, the bamboo Charcoal Adsorption layer of honeycomb texture can improve erasure effect further simultaneously, first melt-blown cotton layer be respectively arranged with the second spray cotton layer over and under, the 3rd cotton layer of spray, sound is successively via the second cotton layer of spray, first melt-blown cotton layer and the cotton layer of the 3rd spray, noise can be carried out the elimination of multilamellar, on the other hand can adapt to the absorption to different frequency noise, the setting of foil insulation is capable of the insulation of acoustical cotton, there is more preferable heat insulation effect.
Accompanying drawing explanation
Fig. 1 is the structural representation of high-efficiency sound-absorbing heat insulation foam sectional view in this utility model embodiment.
The melt-blown cotton layer of label implication in figure: 1-first；The melt-blown cotton layer of 2-second；The upper nonwoven layer of 3-；4-bamboo Charcoal Adsorption layer；The melt-blown cotton layer of 5-the 3rd；Nonwoven layer under 6-；7-the second foil insulation；8-non-drying glue layer.
Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, detailed description of the invention of the present utility model is described in further detail.Following example are used for illustrating this utility model, but are not limited to scope of the present utility model.
As shown in Figure 1, a kind of high-efficiency sound-absorbing heat insulation foam, including acoustical cotton body, acoustical cotton body includes the first melt-blown cotton layer 1 and lays respectively at the upper nonwoven layer 3 of its upper and lower surface and lower nonwoven layer 6, upper nonwoven layer 3, lower nonwoven layer 6 respectively and is provided with the second melt-blown cotton layer 2 and the 3rd melt-blown cotton layer 5 between the first melt-blown cotton layer 1, the second described melt-blown cotton layer 2 and the melt-blown density cotton layer 1 melt-blown more than first of the 3rd melt-blown cotton layer 5 are arranged, upper nonwoven layer 3 is provided above bamboo Charcoal Adsorption layer 4, the cross section of bamboo Charcoal Adsorption layer 4 is honeycomb texture, lower nonwoven layer 6 be respectively arranged below foil insulation 7 and non-drying glue layer 8.
In the present embodiment, the first described melt-blown cotton layer 2 of melt-blown cotton layer 1, second and the 3rd melt-blown cotton layer 5 are formed by pp and pet material mixing is melt-blown.
Operation principle of the present utility model: the setting of bamboo Charcoal Adsorption layer 4 has adsorption, upper nonwoven layer 3 can be protected, prevent it mouldy and moth, prevent melt-blown cotton layer from producing mouldy, there is higher stability, the bamboo Charcoal Adsorption layer 4 of honeycomb texture can improve erasure effect further simultaneously, first melt-blown cotton layer 1 be respectively arranged with the second melt-blown cotton layer 2 over and under, 3rd melt-blown cotton layer 5, sound is successively via the 3rd melt-blown cotton layer 5, first melt-blown cotton layer 1 and the 3rd melt-blown cotton layer 5, noise can be carried out the elimination of multilamellar, on the other hand can adapt to the absorption to different frequency noise, the setting of foil insulation 7 is capable of the insulation of acoustical cotton, there is more preferable heat insulation effect.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; on the premise of without departing from this utility model know-why; can also make some improvement and modification, these improvement of above-mentioned hypothesis and modification also should be regarded as protection domain of the present utility model.
