Abstract
The utility model discloses a composite non-woven sound-absorbing wool board. The composite non-woven sound-absorbing wool board comprises a sound-absorbing wool board main body, wherein non-woven fabric layers are arranged on a top face and a bottom face of the sound-absorbing wool board in a composite manner. According to the composite non-woven sound-absorbing wool board disclosed by the utility model, as the non-woven fabric layers are arranged on the top face and the bottom face of the sound-absorbing wool board in a composite manner, and a non-woven fabric per se has the characteristic of good sound absorbing effect, sound absorbing effect can be enhanced, strength of the sound-absorbing wool board main body can also be enhanced, and therefore the composite non-woven sound-absorbing wool board is favorable for tailoring, punching, fixing and forming.
Description
Technical field
The utility model relates to acoustical cotton plate material technical field, particularly relates to a kind of compound nonwoven cloth acoustical cotton plate.
Background technology
At present, along with people to improving constantly that life requires, to the requirement of the sound-absorbing effect of acoustical cotton plate also not section improve.Existing acoustical cotton plate is to strengthen sound absorption properties by the surperficial layer of meltblown fibers at the acoustical cotton plate, but effect is general.
The utility model content
For solving the problems of the technologies described above, the utility model provides a kind of sound-absorbing effect good compound nonwoven cloth acoustical cotton plate.
Compound nonwoven cloth acoustical cotton plate of the present utility model comprises acoustical cotton plate main body, and end face and the bottom surface of described acoustical cotton plate main body all are compounded with nonwoven layer.
Further, the thickness of described nonwoven layer is 0.12mm.
Further, the density on described nonwoven layer surface is 13g/m
2
Further, the thickness of described acoustical cotton plate main body is 3mm-50mm.
Further, the density of described acoustical cotton plate body surfaces is 50g/m
2-1000g/m
2
Compared with prior art the beneficial effects of the utility model are:
Compound nonwoven cloth acoustical cotton plate of the present utility model, by end face and the bottom surface compound nonwoven cloth layer in acoustical cotton plate main body, because the good characteristic of sound-absorbing effect that nonwoven fabrics self has, can strengthen sound-absorbing effect, also can strengthen in addition the intensity of acoustical cotton plate main body by the compound nonwoven cloth layer, be conducive to cut out, punching press and fixed-type.
Description of drawings
Fig. 1 is front view of the present utility model;
Fig. 2 is upward view of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for explanation the utility model, but are not used for limiting scope of the present utility model.
As depicted in figs. 1 and 2, a kind of compound nonwoven cloth acoustical cotton plate, comprise the acoustical cotton plate main body 1 that is composited by polypropylene and poly terephthalic acid class plastics, the thickness of acoustical cotton plate main body 1 can be 3mm-50mm, end face and bottom surface in acoustical cotton plate main body 1 all are compounded with the nonwoven layer 2 that thickness is 0.12mm, because the good characteristic of sound-absorbing effect that nonwoven fabrics self has, can strengthen sound-absorbing effect, also can strengthen in addition the intensity of acoustical cotton plate main body by the compound nonwoven cloth layer, be conducive to cut out, punching press and fixed-type.
Compound nonwoven cloth acoustical cotton plate of the present utility model, the density on its nonwoven layer 2 surfaces is 13g/m
2
Compound nonwoven cloth acoustical cotton plate of the present utility model, the density on its acoustical cotton plate main body 1 surface is 50g/m
2-1000g/m
2
The above only is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
