Abstract
The utility model discloses an aluminium foil soundproof cotton, include from last aluminium foil layer, non -woven fabrics puigging, the expanded polytetrafluoroethylene layer that sets gradually extremely down, melt and spout high polymer fibrous layer, expanded polytetrafluoroethylene layer, non -woven fabrics puigging, aluminium foil layer, bond through the gluing agent between each layer, the surface on aluminium foil layer is equipped with a plurality of spaceds arch. An object of the utility model is to provide an inhale sound, the effectual aluminium foil soundproof cotton of sound insulation.
Description
Technical field
The utility model relates to sound absorbent material field, is specifically related to a kind of aluminium foil Sound-proof material.
Background technology
Noise directly affects the physical and mental health of people and the raising of quality of life, is in noise environment for a long time, 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. Sound-proof material, it is possible to the high-frequency noises vibrational energy produced in life is converted to the kinetic energy of the fine count fiber of Sound-proof material inside and leads into heat energy and disappear, reach the function of absorbing sound and lowering noise.
Sound-proof material can be superimposed with multi-layer nonwoven fabrics, or other materials of arranging in pairs or groups make sound-absorbing, sound-proof 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 kind of gap has adsorption function, therefore, aluminium foil Sound-proof material can be set to porous material, has good sound-absorbing, soundproof effect, Sound-proof material is widely used in the industries such as building, electrical equipment, automobile, machinery as a kind of cushioning material, mainly plays the effect of sound insulation.
Practical novel content
The purpose of this utility model is the aluminium foil Sound-proof material providing a kind of sound-absorbing, soundproof effect good.
In order to realize above-mentioned purpose, the technical solution adopted in the utility model is:
A kind of aluminium foil Sound-proof material, it is characterized in that: comprise under arrange successively aluminium foil layer, non-woven fabrics pugging, eptfe layer, melt-blown high polymer fibre layer, eptfe layer, non-woven fabrics pugging, aluminium foil layer, between each layer by sizing agent bonding; The outside surface of described aluminium foil layer is provided with the projection at some intervals.
The utility model is also set to further, and described melt-blown high polymer fibre layer is meltblown polypropylene fibres thin layer.
The utility model is also set to further, and described eptfe layer is grease-proof and waterproof modification eptfe layer.
The utility model is also set to further, and described non-woven fabrics pugging is made up of non-woven fabrics, and thickness is 0.08-0.17mm.
The utility model has following advantage compared to existing technology: (1) melt-blown high polymer fibre layer and eptfe layer formed have a large amount of, that interpenetrate, from table to the material of inner micropore. This many micropores matter sound absorbent material well can fall sound consumption; (2) aluminium foil layer plays the effect strengthening product strength, and has good deadening, and coordinates non-woven fabrics pugging, can reach good sound-absorbing, soundproof effect; (3) outside surface of aluminium foil layer is provided with the projection at some intervals, it is possible to absorbs, reflect more noise, and noise absorption is intercepted so that this aluminium foil Sound-proof material has sound insulation noise reduction effect very efficiently.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Number in the figure implication: 1-aluminium foil layer; 2-non-woven fabrics pugging; 3-eptfe layer; 4-is protruding; The melt-blown high polymer fibre layer of 5-.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail. Following examples are 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 aluminium foil Sound-proof material, comprise under arrange successively aluminium foil layer 1, non-woven fabrics pugging 2, eptfe layer 3, melt-blown high polymer fibre layer 5, eptfe layer 3, non-woven fabrics pugging 2, aluminium foil layer 1, between each layer by sizing agent bonding; The outside surface of described aluminium foil layer 1 is provided with the projection 4 at some intervals, and protruding 4 is circular arc, and sound is had good launching effect by protruding 4, makes the soundproof effect of aluminium foil layer 1 better, and described non-woven fabrics pugging 2 is made up of non-woven fabrics, and thickness is 0.08-0.17mm.
Described melt-blown high polymer fibre layer 5 is meltblown polypropylene fibres thin layer, and described eptfe layer 3 is grease-proof and waterproof modification eptfe layer.
Melt-blown superpolymer ultra-fine fibre (PP polypropylene or PET polyester) random melt-blown distribution is bonded together and forms thin layer micropore clearance material, white appearance, smooth, neither too hard, nor too soft, material fiber fineness is 1��10 ��m, there is bigger specific surface area, higher porosity (> 75%), ultra-fine fibre stochastic distribution provides more heat bonding chance between fiber. by this melt-blown superpolymer ultra-fine fibre and expanded PTFE (ePTFE) film (micropore diameter, at 0.01��20 ��m, every square centimeter has several hundred million micro-porous permeable gaps) compound. after melt-blown superpolymer ultra-fine fibre layer and expanded PTFE (ePTFE) Film laminated, its structure is: material has a large amount of, interpenetrate, from table to inner micropore, namely also there is certain ventilation property. the sound-absorbing principle of many micropores matter sound absorbent material is vibrate air when passing in and out from slot, and air molecule and material and self friction, be transformed into heat energy acoustic energy, consumed. Kong Yue is how more close, sound-absorbing ability is stronger, define the specific function novel material of a kind of high performance efficient full sound-absorbing frequently, when sound wave incident is to this many micropores novel material surface, cause the air vibration in micropore, due to viscous resistance and the conduction of heat of friction resistance and air, quite a few acoustic energy is converted into heat energy, sound equipment acoustic pressure reduces 4��6dB in all frequency range, it is complete that sound-absorbing effect is fairly obvious frequently, especially centering low frequency noise absorbs better, it is applied on high-fidelity audio equipment, noise can be absorbed in whole frequency range, leave dulect music, it is used in indoor environment, on automobile or electromechanical equipment, noise is big by degree of absorption, its neighbourhood noise will greatly reduce, to people's comfortable environment.
The above is only preferred implementation 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 making some improvement and modification, these improvement of above-mentioned hypothesis and modification also should be considered as protection domain of the present utility model.
