Abstract
The utility model discloses a kind of environmental-protection type sound-absorbing cotton, comprise nonwoven layer, acoustical cotton layer A, spring wire layer, acoustical cotton layer B, adhesive-layer and off-style paper layer, nonwoven layer, acoustical cotton layer A, spring wire layer, acoustical cotton layer B, adhesive-layer and off-style paper layer are installed on a neighboring layer from top to bottom successively.
Description
Technical field
The utility model belongs to acoustical material technical field, particularly relates to a kind of environmental-protection type sound-absorbing cotton.
Background technology
Acoustical cotton can be divided into glass fibre acoustical cotton and dacron acoustical cotton, and these two kinds of products are had nothing in common with each other, and sound-absorbing effect is substantially the same.But glass fibre not environmentally, be not easy to construction, when touching the skin of people, easily cause itch.Car acpistocs acoustical cotton is installed on the material between automotive upholstery (comprising ceiling, door-plate, hat rack, luggage case etc.) and body of a motor car, have the features such as sound-absorbing, heat insulation, damping, therefore car acpistocs acoustical cotton generally adopts dacron acoustical cotton fiber.The quality of acoustical cotton sound absorption qualities directly can affect the driver comfort of car load, and serious also can work the mischief to the body and mind of driver and crew.At present, the structure of car acpistocs acoustical cotton is simple, and be not coupled to the physical property that sound wave transmits, therefore its attraction power is had a greatly reduced quality.
Noise spectrum is known together as below 500Hz is low frequency at present, 500 ~ 2000Hz is intermediate frequency, more than 2000Hz is high frequency, and the cotton frequency range sound wave mainly absorbing more than 2000HZ of automobile acoustical absorption, its absorptivity reaches more than 80%, only have between 35%-50% to the absorptivity of the noise of intermediate frequency, intermediate frequency sound-absorbing effect is not obvious.
Existing acoustical cotton as a kind of gasket material, between the surface that a lot of use occasion needs this kind of acoustical cotton material to fix or be pasted onto implements or interlayer.Need scene to stamp glue with brush during concrete operations on product used or acoustical cotton, then acoustical cotton material is pasted on implements and is also fixed, again fixture is removed after the glue solidifies.Operation is more loaded down with trivial details, and installation effectiveness is low, and quick setting cement used generally volatile go out objectionable impurities, adverse effect is caused to human body or environment.
Therefore a kind of comparatively environmental protection of design is necessary and the acoustical cotton higher to mid-frequency noise contribution ratios.
Utility model content
For above existing Problems existing, the utility model provides a kind of environmental-protection type sound-absorbing cotton, adopt dacron acoustical cotton fiber, the feature of environmental protection is good, and due to the effect of environment-friendly type self-adhesive, during use, paste operation is more convenient, and the volatile matter simultaneously eliminated when using common glue to paste in glue causes adverse effect to human body or environment.
The technical solution of the utility model is:
The utility model provides a kind of environmental-protection type sound-absorbing cotton, comprise nonwoven layer, acoustical cotton layer A, spring wire layer, acoustical cotton layer B, adhesive-layer and off-style paper layer, described nonwoven layer, acoustical cotton layer A, spring wire layer, acoustical cotton layer B, adhesive-layer and off-style paper layer are installed on a neighboring layer from top to bottom successively.
Further, described acoustical cotton layer A adopts low-density dacron acoustical cotton fiber to make, and plays main sound absorption.
Further, described acoustical cotton layer B adopts highdensity dacron acoustical cotton fiber to make, and plays secondary sound absorption.
Further, described spring wire layer adopts elastomeric spring wire to make, and absorbs the vibration of described acoustical cotton layer A.
Further, described adhesive-layer adopts environmental-protective self-adhering type glue to make, and play fixed supporting role to the sound-absorbing structure that described acoustical cotton layer A, spring wire layer and acoustical cotton layer B form.
The utility model is owing to have employed above-mentioned technology, and making it compared with prior art concrete positive beneficial effect is:
1, the utility model adopts dacron acoustical cotton fiber, and the feature of environmental protection is good.
2, the utility model is due to the effect of environment-friendly type self-adhesive, and during use, paste operation is more convenient, and the volatile matter simultaneously eliminated when using common glue to paste in glue causes adverse effect to human body or environment.
3, the utility model sound-absorbing effect is good, and intermediate frequency sound-absorbing effect is good.
4, the utility model structure is simple, safe and reliable, has good market outlook.
5, the utility model good product performance, long service life.
Accompanying drawing explanation
Fig. 1 is the one-piece construction stereographic map of the utility model structure.
In figure: 1-nonwoven layer, 2-acoustical cotton layer A, 3-spring wire layer, 4-acoustical cotton layer B, 5-adhesive-layer, 6-off-style paper layer.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail, and embodiment of the present utility model includes but not limited to the following example.
Embodiment: to achieve these goals, the technical solution adopted in the utility model is as follows:
As shown in Figure 1, the utility model provides a kind of environmental-protection type sound-absorbing cotton, comprise nonwoven layer 1, acoustical cotton layer A2, spring wire layer 3, acoustical cotton layer B4, adhesive-layer 5 and off-style paper layer 6, nonwoven layer 1, acoustical cotton layer A2, spring wire layer 3, acoustical cotton layer B4, adhesive-layer 5 and off-style paper layer 6 are installed on a neighboring layer from top to bottom successively.
The utility model is set to further: acoustical cotton layer A2 adopts low-density dacron acoustical cotton fiber to make, and plays main sound absorption.
The utility model is set to further: acoustical cotton layer B4 adopts highdensity dacron acoustical cotton fiber to make, and plays secondary sound absorption.
The utility model is set to further: spring wire layer 3 adopts elastomeric spring wire to make, and absorbs the vibration of acoustical cotton layer A2.
The utility model is set to further: adhesive-layer 5 adopts environmental-protective self-adhering type glue to make, and play fixed supporting role to the sound-absorbing structure that acoustical cotton layer A2, spring wire layer 3 and acoustical cotton layer B4 form.
By adopting technique scheme, when the utility model is in normal operating conditions, the acoustical cotton provided by the utility model by adhesive-layer 5 is installed in desired location, sound enters from spinning layer of cloth 1, because acoustical cotton layer A2 adopts low-density dacron acoustical cotton fiber to make, play main sound absorption, acoustical cotton layer B4 adopts highdensity dacron acoustical cotton fiber to make, play secondary sound absorption, spring wire layer 3 wherein between acoustical cotton layer A2 and acoustical cotton layer B4, the vibration of acoustical cotton layer A2 is absorbed, abundant is heat energy by changes mechanical energy, reach sound-absorbing and delay the effect of shaking.
Above an embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
