Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described in further detail.
Embodiment one: a kind of cabin sound-heat insulated cushion, as it is shown in figure 1, include six layers, is followed successively by aluminium foil layer 1 from bottom to top,
First nonwoven layer 2, PU layer 3, EVA layer the 4, second nonwoven layer 5 and Sound-proof material layer 6, this heat insulating mattress is to be colded pressing by preheating heat
Molding.Wherein, the upper and lower surface of EVA layer 4 is provided with projection 7 and pit 8, pit 8 or pit 8 are arranged in strip
Or uniform protruding 7 or the cross section of pit 8 be semicircle.In being increased EVA layer 4 and PU layer 3 and the second nonwoven layer 5
Contact area, when this heat insulating mattress in use, electromotor the waste heat transmitted makes EVA layer 4 have viscosity and makes EVA layer
4 is bigger with PU layer 3 and the second nonwoven layer 5 contact force, connects tightr.
Orlop is aluminium foil, and the heat that electromotor produces can be reflected by aluminium foil, it is thus possible to reduces directly heat and passes
Lead the heat on heat insulating mattress；Aluminium foil arranges the first nonwoven layer 2, there is protection against the tide, ventilative, pliable and tough, light weight, the most combustion-supporting etc.
Characteristic, thus the higher aluminium foil of Contact Temperature will not produce burning or the ill effects such as qualitative change occur；Aluminium foil layer 1 is arranged
PU layer 3, PU material has the effect of good shock-absorbing noise reduction, it is thus possible to weakened after absorption by the noise that electromotor produces,
There is good heat-blocking action simultaneously；EVA layer 4 is set on PU layer 3, EVA material while there is good effect of heat insulation every
Audio fruit to be significantly better than other quieter material, and EVA material has viscosity and can have good when temperature is higher
Interconnection function, by increasing capacitance it is possible to increase PU and the non-woven fabrics of adjacent two layers firmly connect, thus avoid layering or the phenomenon peeled off, meanwhile,
EVA material has bigger weight can increase the weight of heat insulating mattress such that it is able to increase the counterweight of vehicle；Arrange on EVA layer 4
Second nonwoven layer 5, it is possible to further with its characteristic, further enhances sound insulation and heat insulation effect: in the second nonwoven layer 5
Sound-proof material layer 6 is set, utilizes acoustical cotton that remaining noise is done last absorption, it is to avoid noise spreads out of.The sound insulation of above-mentioned cabin every
Heat pad is by repeatedly utilizing multiple material to carry out sound insulation repeatedly and heat insulation process, thus has more preferable sound insulation and heat insulation effect
Really.
Embodiment two: a kind of cabin sound-heat insulated cushion, as in figure 2 it is shown, include seven layers, is followed successively by aluminium foil layer 1 from bottom to top,
Isolation conduction type insulating moulding coating layer 10(rare-earth thermal insulating coating or composite aluminium-magnesium-silicate insulating moulding coating), the first nonwoven layer 2, PU layer
3(PU is soft to be brewed to), EVA layer the 4, second nonwoven layer 5 and Sound-proof material layer 6(environmental protection Sound-proof material), simultaneously layer on Sound-proof material 6 uniformly
It is provided with multiple Magnet 9, therefore when using this sound-heat insulated cushion, owing to electromotor or other structures are that ferrous materials is made,
Therefore, it is possible to this sound-heat insulated cushion is absorbed and fixed in electromotor or other structures by Magnet 9 easily.This heat insulating mattress is
By preheating cold press molding.Wherein, the upper and lower surface of EVA layer 4 is provided with projection 7 and pit 8, projection 7 or recessed
The cross section in hole 8 is triangle.In being increased EVA layer 4 and PU layer 3 and the contact area of the second nonwoven layer 5, when this heat insulating mattress
During use is made, electromotor the waste heat transmitted makes EVA layer 4 have viscosity and makes EVA layer 4 and PU layer 3 and second
Nonwoven layer 5 contact force is bigger, connects tightr.
Orlop is aluminium foil, and the heat that electromotor produces can be reflected by aluminium foil, it is thus possible to reduces directly heat and passes
Lead the heat on heat insulating mattress；Aluminium foil arranges isolation conduction type insulating moulding coating layer 10, used here as rare-earth thermal insulating coating or
Composite aluminium-magnesium-silicate insulating moulding coating, most heat can be reflected away by aluminium foil, but also can remain by some heat, because of
This is further coated with completely cutting off conduction type insulating moulding coating layer 10 on aluminium foil layer 1, and it is further that this insulating moulding coating layer can completely cut off heat
To other partial conductance of heat insulating mattress, therefore, it is possible to produce more preferable effect of heat insulation；Set on isolation conduction type insulating moulding coating layer 10
Put the first nonwoven layer 2, there is protection against the tide, ventilative, pliable and tough, light weight, the characteristic such as the most combustion-supporting, thus the higher aluminium foil of Contact Temperature is not
Burning can be produced or the ill effects such as qualitative change occur；Arranging PU layer 3 on aluminium foil layer 1, PU is soft, and the PU layer 3 being brewed to has more
The effect of good shock-absorbing noise reduction, it is thus possible to weakened after absorption by the noise that electromotor produces, has good heat insulation simultaneously
Effect；Arranging EVA layer 4 on PU layer 3, EVA material soundproof effect while having good effect of heat insulation to be significantly better than it
Its quieter material, and EVA material has viscosity and can have good interconnection function when temperature is higher, by increasing capacitance it is possible to increase phase
PU and the non-woven fabrics of adjacent two-layer firmly connect, thus avoid layering or the phenomenon peeled off, and meanwhile, EVA material has bigger weight
Amount can increase the weight of heat insulating mattress such that it is able to increases the counterweight of vehicle；Second nonwoven layer 5 is set on EVA layer 4, it is possible to
Further with its characteristic, further enhance sound insulation and heat insulation effect: in the second nonwoven layer 5, Sound-proof material layer 6, sound insulation are set
Cotton layer 6 is made for environmental protection Sound-proof material, more environmentally-friendly relative to the Sound-proof material using other classifications, it is to avoid user contact produces wound
Evil, utilizes acoustical cotton that remaining noise is done last absorption, it is to avoid noise spreads out of.Above-mentioned cabin sound-heat insulated cushion is by repeatedly
Utilize multiple material to carry out sound insulation repeatedly and heat insulation process, thus there is more preferable sound insulation and effect of heat insulation.
The above is only preferred implementation of the present utility model, and protection domain of the present utility model is not limited merely to
Above-described embodiment, all technical schemes belonged under this utility model thinking belong to protection domain of the present utility model.Should refer to
