The heat-insulation sound-adsorption damping gasket for the vehicle can effectively adsorb sound, insulate heat and carry out damping and vibration reduction.
Description
Technical field
The utility model relates to a kind of automotive interior structure, especially relates to a kind of automobile heat insulation sound absorbent damping liner.
Background technology
Noise, vibration and comfortableness are to weigh the integrated technology index of Hyundai Motor manufacture level.The material effects of present automobile-used sound-absorbing, sound insulation, vibration damping, sealing etc. is more single, and sound-absorbing material mostly is polyurethane or fiber-like material, can't bring into play good damping action, and the weakening effect of rubber damping material centering high frequency noise is relatively poor.As the Chinese patent notification number be: CN2604758Y, in disclosed a kind of abatvoix on February 25th, 2004, it is made up of sound absorbing layer and gripper shoe, sound absorbing layer is to pulverize the back compacting by string to form, there is layer of non-woven fabric on two sides at sound absorbing layer, sound absorbing layer is fixed on the gripper shoe by staple, scribbles one deck wax around sound absorbing layer.Though this patent structure is simple, sound-absorbing effect good.But do not have damping vibration attenuation and heat insulation effect.
Summary of the invention
The utility model mainly is at single problems of liner effect such as existing sound-absorbing, sound insulation, vibration dampings, and a kind of sound-absorbing effectively, automobile heat insulation sound absorbent damping liner heat insulation and damping vibration attenuation are provided.
The purpose of this utility model mainly is achieved by following proposal: a kind of automobile heat insulation sound absorbent damping liner, automobile comprises the thermal insulation layer that damping layer that butyl rubber makes, sound absorbing layer that melmac is made and metal aluminum foil are made with heat insulation sound absorbent damping liner, described damping layer and sound absorbing layer are bonding, and described sound absorbing layer and thermal insulation layer are bonding.Because the numerical value of the damping factor of butyl rubber material own is higher, so the damping layer that butyl rubber is made can suppress the low-frequency vibration noise that vehicle body panel beating excited target produces.The heat resistance of melmac material is good, especially at high temperature the acoustical behavior of material is strong, and the melmac material has outstanding sound absorption properties and hear resistance, light weight, in the good acoustical behavior of performance, strengthened the heat resistance of attractable layer, so the sound absorbing layer that melmac is made sound-absorbing effectively.The coefficient of heat conduction of the material of metal aluminum foil own is less, can completely cut off heat well, so the thermal insulation layer that metal aluminum foil is made can make the heat that is delivered to the crew module reduce.Because metal aluminum foil surface protection effect, material is difficult for mouldy, has favorable durability.Damping layer, sound absorbing layer and thermal insulation layer are bonded in the vehicle body successively, can play damping vibration attenuation, sound-absorbing and heat insulation effect effectively, improve car comfort.
As preferably, described damping layer thickness is 1.2mm～2mm.The numerical value of the damping factor of butyl rubber material own is higher, and for the angle consideration of saving material and saving the space, the thickness of damping layer is arranged on the function that 1.2mm～2mm is enough to realize damping vibration attenuation.
As preferably, described sound absorbing layer thickness is 5mm～10mm.The sound absorbing layer material is a melmac, and density of material only is 9Kg/m
3, for the angle consideration of saving material and saving the space, the thickness of sound absorbing layer is arranged on the function that 5mm～10mm is enough to realize sound-absorbing.
As preferably, described thermal insulation layer thickness is 0.8mm～1.2mm.The metal aluminum foil surface has protective effect, and material is difficult for mouldy, has favorable durability, and for the angle consideration of saving material and saving the space, thermal insulation layer thickness is arranged on 0.8mm～1.2mm is enough to realize heat insulating function.
Therefore, automobile of the present utility model possesses following advantage with heat insulation sound absorbent damping liner: 1, the damping layer made of butyl rubber can suppress the low-frequency vibration noise that vehicle body panel beating excited target produces, and has good damping vibration attenuation effect; 2, the sound absorbing layer made of melmac has the good sound absorption effect; 3, the coefficient of heat conduction of thermal insulation layer made of metal aluminum foil own is less, can completely cut off heat well, has good effect of heat insulation.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model.
Illustrate: 1-damping layer, 2-sound absorbing layer, 3-thermal insulation layer, the outer panel beating of 4-vehicle body.
The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
As shown in Figure 1, a kind of automobile heat insulation sound absorbent damping liner, automobile is to constitute by damping layer 1, sound absorbing layer 2 and thermal insulation layer 3 are bonding successively with heat insulation sound absorbent damping liner.Damping layer 1 is to be made by butyl rubber, and thickness is 1.2mm～2mm, and preferred thickness is 1.5mm; Sound absorbing layer 2 is to be made by melmac, and thickness is 5mm～10mm, and preferred thickness is 8mm; Thermal insulation layer 3 is to be made by metal aluminum foil, and thickness is 0.8mm～1.2mm, and preferred thickness is 0.8mm.Because butyl rubber self has viscosity, so a side of damping layer 1 is bonding with the medial surface of the outer panel beating 4 of vehicle body by self viscosity, it is bonding that a side of self viscosity and sound absorbing layer 2 is passed through in the another side of damping layer 1.Another side of sound absorbing layer 2 is bonding by acrylate adhesive and thermal insulation layer 3.
Because the numerical value of the damping factor of butyl rubber material own is higher, the numerical value of damping factor is more than 0.2 under the room temperature condition, so its effectiveness in vibration suppression excellence, when the vehicle body steel plate vibrates, butyl rubber can produce repeatedly repeated deformation, as stretching, compression, shearing etc., thereby make system change a part of elastic energy into irreversible heat energy dissipation.The damping layer 1 that butyl rubber is made can reach the purpose of damping vibration attenuation.The heat resistance of melmac material is better, and especially at high temperature the acoustical behavior of material is strong, and the density of material only is 9Kg/m in addition
3, much smaller than the density of polyurethane.The loose structure of melmac more helps the frictional dissipation to acoustic wave energy, and the sound absorbing layer 2 that melmac is made has the good sound absorption effect.The coefficient of heat conduction of metal aluminum foil itself is less, can completely cut off heat well, and the heat that is delivered to the crew module is reduced.And because the protective effect of aluminium foil surface, material is difficult for mouldy, has favorable durability.The thermal insulation layer that replaces nonwoven to make with metal aluminum foil has good effect of heat insulation, and is difficult for mouldy.Liner is composited by damping material, attractive material and heat-barrier material, has improved the comfortableness of automobile greatly.
Should be understood that this embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
