Abstract
The utility model belongs to acoustical cotton technical field, specifically related to a kind of automobile acoustical absorption cotton, including acoustical cotton layer body, two sides are provided with groove arranged in parallel above and below the acoustical cotton layer body, adjacent grooves are provided with boss, the upper side of the acoustical cotton layer body is covered with upper nonwoven layer, the downside of the acoustical cotton layer body is covered with lower nonwoven layer, the boss covered by upper nonwoven layer is Nian Jie with upper nonwoven layer, the boss covered by lower nonwoven layer is Nian Jie with lower nonwoven layer, and the groove is filled with bamboo carbon powder.The smell and organic principle that the bamboo carbon powder of setting volatilizees to acoustical cotton play a part of absorption, the contact area of bamboo carbon powder and acoustical cotton layer body is effectively increased by way of groove fills bamboo carbon powder, multiple grooves arranged in parallel are set on the one hand to make the absorption of bamboo carbon powder uniform, on the other hand bamboo carbon powder is made to be dispersed into many parts, avoid bamboo carbon powder aggregation during using acoustical cotton agglomerating, influence adsorption effect.
Description
Technical field
The utility model belongs to acoustical cotton technical field, and in particular to a kind of automobile acoustical absorption cotton.
Background technology
With the fast development of science and technology, automobile increasingly becomes the indispensable vehicles, use in the extreme frequently and
Generally, and at present the material of the absorptive product of automotive interior is main based on waste woven felt, be with waste and old recovery based on cotton
Raw material machining is formed.It has the disadvantage that weight is big, smell is big, Volatile Organic Components are higher, and the smell that it volatilizees is serious
Influence environment inside car.
Utility model content
The purpose of this utility model is：In view of the shortcomings of the prior art there is provided a kind of automobile acoustical absorption cotton, acoustical cotton is reduced
The volatilization of organic principle and smell, improves in-car air ambient.
To achieve these goals, the utility model is adopted the following technical scheme that：
Two sides are provided with parallel above and below a kind of automobile acoustical absorption cotton, including acoustical cotton layer body, the acoustical cotton layer body
The groove of arrangement, adjacent grooves are provided with boss, and the upper side of the acoustical cotton layer body is described covered with upper nonwoven layer
The downside of acoustical cotton layer body is covered with lower nonwoven layer, and the boss covered by upper nonwoven layer is Nian Jie with upper nonwoven layer,
The boss covered by lower nonwoven layer is Nian Jie with lower nonwoven layer, and the groove is filled with bamboo carbon powder.
As a kind of improvement of automobile acoustical absorption cotton described in the utility model, the width ratio of the groove and the boss is not
Less than 2：1.
As a kind of improvement of automobile acoustical absorption cotton described in the utility model, the boss covered by upper nonwoven layer passes through glue
Water or hot melt are Nian Jie with upper nonwoven layer.
As a kind of improvement of automobile acoustical absorption cotton described in the utility model, the boss covered by lower nonwoven layer passes through glue
Water or hot melt are Nian Jie with lower nonwoven layer.
As a kind of improvement of automobile acoustical absorption cotton described in the utility model, the upper nonwoven layer is protected covered with upper aluminium foil
Warm layer.
As a kind of improvement of automobile acoustical absorption cotton described in the utility model, the lower nonwoven layer is protected covered with lower aluminium foil
Warm layer.
The beneficial effects of the utility model are：A kind of automobile acoustical absorption cotton, including acoustical cotton layer body, the sound-absorbing are provided
Two sides are provided with groove arranged in parallel above and below cotton layer body, and adjacent grooves are provided with boss, the acoustical cotton layer body
Upper side covered with upper nonwoven layer, the downside of the acoustical cotton layer body is covered with lower nonwoven layer, by upper non-woven fabrics
The boss of layer covering is Nian Jie with upper nonwoven layer, and the boss covered by lower nonwoven layer is Nian Jie with lower nonwoven layer, the groove
Filled with bamboo carbon powder.The smell and organic principle that the bamboo carbon powder of setting volatilizees to acoustical cotton play a part of absorption, pass through
The mode of groove filling bamboo carbon powder is effectively increased the contact area of bamboo carbon powder and acoustical cotton layer body, sets multiple parallels
On the one hand the groove of row makes the absorption of bamboo carbon powder uniform, bamboo carbon powder is dispersed into many parts, it is to avoid to use sound-absorbing
Bamboo carbon powder aggregation is agglomerating during cotton, influences adsorption effect.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is part A enlarged drawing in Fig. 1.
Wherein, 1. acoustical cottons layer body, 11. grooves, 12. boss, nonwoven layer, 3. times nonwoven layers, 4. bamboo charcoals on 2.
Powder, foil insulation, 6. times foil insulations on 5..
Embodiment
Further detailed is made to the utility model and its advantage below in conjunction with embodiment and Figure of description
Describe in detail bright, still, embodiment of the present utility model is not limited thereto.
As depicted in figs. 1 and 2, a kind of automobile acoustical absorption cotton, including acoustical cotton layer body 1, the acoustical cotton layer body is about 1
Two sides are provided with groove 11 arranged in parallel, and adjacent grooves 11 are provided with boss 12, the upside of the acoustical cotton layer body 1
Face is covered with upper nonwoven layer 2, and the downside of the acoustical cotton layer body 1 is covered with lower nonwoven layer 3, by upper nonwoven layer 2
The boss 12 of covering is be bonded with upper nonwoven layer 2, and the boss 12 covered by lower nonwoven layer 3 is be bonded with lower nonwoven layer 3, described
Groove 11 is filled with bamboo carbon powder 4.Smell and organic principle that the bamboo carbon powder 4 of setting volatilizees to acoustical cotton play the work of absorption
With, the contact area of bamboo carbon powder 4 and acoustical cotton layer body 1 is effectively increased by way of groove 11 fills bamboo carbon powder 4, if
Putting multiple one side of groove 11 arranged in parallel makes the absorption of bamboo carbon powder 4 uniform, is on the other hand dispersed into bamboo carbon powder 4 many
Part, it is to avoid assemble that agglomerating (boss 12 and upper nonwoven layer 2 or lower nonwoven layer 3 are viscous using bamboo carbon powder during acoustical cotton 4
