Abstract
The utility model belongs to sound-absorbing material technical field, specifically related to a kind of environmental-protection type sound-absorbing cotton, including the nonwoven layer being laminated from top to bottom successively, the first acoustical cotton layer, the second acoustical cotton layer, adhesive-layer and off-style paper layer, the first acoustical cotton layer forms the first silencing groove with being provided with the contact surface of second acoustical cotton layer between some first boss, adjacent first boss.The first silencing groove formed between the adjacent first boss, after the first acoustical cotton layer absorbs sound, effectively absorbs the vibration of the first acoustical cotton layer, reduces and the second acoustical cotton layer is impacted, and the overall sound-absorbing effect of acoustical cotton is effectively ensured.
Description
Technical field
The utility model belongs to sound-absorbing material technical field, and in particular to a kind of environmental-protection type sound-absorbing cotton.
Background technology
Acoustical cotton can be divided into glass fibre acoustical cotton and polyester fiber acoustical cotton, and both products are had nothing in common with each other, sound-absorbing
Effect is essentially the same.But glass fibre is not environmentally, construction is not easy to, easily causes itch when touching the skin of people.Vapour
Car acoustics acoustical cotton is mounted to material of the automotive upholstery (including ceiling, door-plate, hat rack, luggage case etc.) between body of a motor car
Material, the features such as with sound-absorbing, heat-insulated, damping, therefore car acpistocs acoustical cotton typically uses polyester fiber sound-absorbing cotton fiber.Sound-absorbing
The quality of cotton sound absorption qualities can directly affect the driver comfort of vehicle, and serious can also cause danger to the body and mind of driver and crew
Evil.At present, car acpistocs acoustical cotton is simple in construction, is not fitted into the physical property of sound wave transmission, therefore its attraction power
Have a greatly reduced quality.
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 environmental-protection type sound-absorbing cotton, to improve suction
The sound-absorbing effect of sound cotton.
To achieve these goals, the utility model is adopted the following technical scheme that：
A kind of environmental-protection type sound-absorbing cotton, including be laminated from top to bottom successively nonwoven layer, the first acoustical cotton layer, the second sound-absorbing
Cotton layer, adhesive-layer and off-style paper layer, if first acoustical cotton layer on the contact surface of second acoustical cotton layer with being provided with
The first silencing groove is formed between dry first boss, adjacent first boss.
It is used as a kind of improvement of environmental-protection type sound-absorbing cotton described in the utility model, the second acoustical cotton layer and described first
It is provided between some second boss, adjacent second boss on the contact surface of acoustical cotton layer and forms the second silencing groove, described the
One silencing groove is covered by the second boss, and second silencing groove is covered by the first boss.
As a kind of improvement of environmental-protection type sound-absorbing cotton described in the utility model, the first acoustical cotton layer is fine using polyester
Dimension sound-absorbing cotton fiber is made.
As a kind of improvement of environmental-protection type sound-absorbing cotton described in the utility model, the second acoustical cotton layer is fine using polyester
Dimension sound-absorbing cotton fiber is made.
As a kind of improvement of environmental-protection type sound-absorbing cotton described in the utility model, the adhesive-layer uses environmental-protective self-adhering type glue
Water is made.
The beneficial effects of the utility model are：A kind of environmental-protection type sound-absorbing cotton is provided, including be laminated from top to bottom successively
Nonwoven layer, the first acoustical cotton layer, the second acoustical cotton layer, adhesive-layer and off-style paper layer, the first acoustical cotton layer with it is described
It is provided with the contact surface of second acoustical cotton layer between some first boss, adjacent first boss and forms the first silencing groove.Phase
The first silencing groove formed between the adjacent first boss, after the first acoustical cotton layer absorbs sound, effectively absorbs first and inhales
The vibration of sound cotton layer, reduces and the second acoustical cotton layer is impacted, and the overall sound-absorbing effect of acoustical cotton is effectively ensured.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Wherein, 1. nonwoven layer, 2. first acoustical cottons layer, 21. first boss, 22. first silencing grooves, 3. second acoustical cottons
