Abstract
The utility model discloses a sound cotton inhales, inhale line including melting spray -up and two, inhale line for two and use and melt the spray -up and melting the spray -up both sides as the setting of symmetry axis symmetry, each inhale line and include enhancement layer, non -woven fabrics puigging, the high polymer fibre sound absorbing layer that sets gradually from inside to outside, just melt between spray -up and the enhancement layer, between enhancement layer and the non -woven fabrics puigging, all be provided with the rubberised layer between non -woven fabrics puigging and the high polymer fibre sound absorbing layer, the enhancement layer is aluminium honeycomb perforation abatvoix, high polymer fibre sound absorbing layer all be wavy setting towards the outside. An object of the utility model is to provide a sound cotton inhales that absorbing effect is good.
Description
Technical field
The utility model relates to sound-absorbing material field, is specifically related to a kind of acoustical cotton.
Background technology
Noise directly affects the physical and mental health of people and the raising of quality of life, is in for a long time in noise circumstance, and hearing loss can be caused even may to bring out some diseases, away from noise, and what we can accomplish is exactly sound-absorbing and sound insulation.Acoustical cotton, can be converted to the kinetic energy of the fine count fiber of acoustical cotton inside by the high-frequency noises vibrational energy produced in life and lead into heat energy and disappear, reach the function of absorbing sound and lowering noise.
Acoustical cotton can be superimposed with multi-layer nonwoven fabrics, or collocation other materials makes sound-absorbing, acoustic material.Non-woven fabrics is that textile staple or long filament are carried out orientation or random alignment, form fibre net structure, present many tiny gaps, this gap has adsorption function, therefore, acoustical cotton can be set to porous material, has good sound-absorbing, soundproof effect, acoustical cotton is widely used in the industries such as building, electrical equipment, automobile, machinery as a kind of gasket material, mainly plays the effect of sound insulation.But all there is more deficiency in existing acoustical cotton product and manufacture method thereof, main manifestations is: sound-absorbing effect is general, cannot meet the high standard requirement of user to its sound-absorbing, therefore need to propose a kind of scheme and solve this problem.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is the acoustical cotton providing a kind of sound-absorbing effect good.
To achieve these goals, the technical solution adopted in the utility model is: a kind of acoustical cotton, it is characterized in that: comprise meltblown layer and two sound-absorbing parts, described two sound-absorbing parts are that symmetry axis is symmetricly set on meltblown layer both sides with meltblown layer, sound-absorbing part described in each comprises the enhancement layer set gradually from inside to outside, non-woven fabrics puigging, high polymer fibre sound absorbing layer, and between described meltblown layer and enhancement layer, between enhancement layer and non-woven fabrics puigging, rubberised layer is provided with between non-woven fabrics puigging and high polymer fibre sound absorbing layer, described enhancement layer is aluminium honeycomb perforated sound-absorbing plate, described high polymer fibre sound absorbing layer toward the outer side all in wavy setting.
The utility model is also set to further, and described meltblown layer is interwoven by hollow terylene and polypropylene.
The utility model is also set to further, and the thickness of described enhancement layer is 2 ~ 4mm.
The utility model has following advantage compared to existing technology: acoustical cotton of the present utility model forms with two sound-absorbing parts being positioned at its both sides by being arranged on middle meltblown layer, sound-absorbing part comprises the enhancement layer set gradually from inside to outside, non-woven fabrics puigging, high polymer fibre sound absorbing layer, enhancement layer plays the effect strengthening product strength, and enhancement layer is aluminium honeycomb perforated sound-absorbing plate, there is good sound-absorbing deadening, and coordinate non-woven fabrics puigging and high polymer fibre sound absorbing layer, reach good sound-absorbing, soundproof effect, be arranged on the equal undulate of outermost high polymer fibre layer to arrange, more noise can be absorbed, intercept from both sides noise absorption like this, the spreading rate of noise is made to be reduced in about 1.5% ~ 2%, this acoustical cotton is made to have sound insulation erasure effect very efficiently.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Number in the figure implication: 1-meltblown layer; 2-enhancement layer; 3-non-woven fabrics puigging; 4-high polymer fibre sound absorbing layer; 5-rubberised layer.
Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
Below with reference to Fig. 1, the utility model is described.
A kind of acoustical cotton, comprise meltblown layer 1 and two sound-absorbing parts, described two sound-absorbing parts with meltblown layer 1 for symmetry axis is symmetricly set on meltblown layer 1 both sides, described meltblown layer 1 is interwoven by hollow terylene and polypropylene, sound-absorbing part described in each comprises the enhancement layer 2 set gradually from inside to outside, non-woven fabrics puigging 3, high polymer fibre sound absorbing layer 4, and between described meltblown layer 1 and enhancement layer 2, between enhancement layer 2 and non-woven fabrics puigging 3, rubberised layer 5 is provided with between non-woven fabrics puigging 3 and high polymer fibre sound absorbing layer 4, described rubberised layer 5 adopts pressure sensitive adhesive adhesive, adhesive strength between each layer is improved greatly, improve the resistance to tension of acoustical cotton, do not allow fugitive, improve the quality of acoustical cotton.
Enhancement layer 2 is aluminium honeycomb perforated sound-absorbing plate, it have be separated to form by several honeycomb cores numerous in hexagonal closed cells, stop the flowing of air, sound wave is hindered, improve acoustic absorptivity, improve the intensity of acoustical cotton self simultaneously, make acoustical cotton have higher structural strength.
High polymer fibre sound absorbing layer 4 toward the outer side all in wavy setting, like this when noise wear be emitted through high polymer fibre sound absorbing layer 4 time, a part is absorbed, and a part by cancelling out each other under waveform diffusion, greatly reduces propagation and the reflection of noise.
The thickness of enhancement layer 2 is 2 ~ 4mm, can reach again the effect of saving material, have higher use cost performance, meet industrial production demand while the enhancement layer of this thickness meets intensity needs shortly.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and modification, these improvement of above-mentioned hypothesis and modification also should be considered as protection domain of the present utility model.
