Abstract
This application provides heat-insulating sound-insulating pad outside a kind of automobile front wall, the outer heat-insulating sound-insulating pad of the automobile front wall includes：First nonwoven layer, the first nonwoven layer lower surface are sequentially provided with the first resin carpet veneer, EVA layer, the second resin carpet veneer and the second nonwoven layer from top to bottom.Sound-absorbing, sound insulation and heat-insulated are carried out by using the sound-absorbing of various materials, sound insulation and insulative properties.The application employs materials of the EVA as puigging, due to EVA have shockproof cushioning, sound insulation, it is heat-insulated the advantages of, the vibrations for automobile front wall metal plate of both having decayed, also increase the effect of sound insulation, larger improves effect of heat insulation.The advantages of EVA also has thermoplasticity good and is easy to shaping, therefore the automobile front wall heat-insulating sound-insulating pad that the application provides has been lifted compared to the automobile front wall heat-insulating sound-insulating pad of conventionally employed adhesive film material in hardness, also can preferably be bonded metal plate.Double-layer resin carpet veneer and two-layer nonwoven layer then serve more preferable sound-absorbing effect and have also beautified the outer heat-insulating sound-insulating pad of automobile front wall.
Description
Technical field
The application is related to auto parts and components field, more particularly to a kind of outer heat-insulating sound-insulating pad of automobile front wall.
Background technology
With expanding economy, the automobile not exclusively offices of office and enterprises and institutions and the instrument ridden instead of walk, vapour
Car has become the first choice of current household consumption, and people for the brand of automobile, safety in addition to claiming, to comfortableness
It is required that also more and more higher, noise intensity increasingly attracts attention in vehicle's passenger compartment.Automobile periphery heat-insulating sound-insulating pad is arranged on vapour
Chinese herbaceous peony encloses driving cabin position, plays a part of heat-insulating sound-insulating.
The sound-heat insulated cushion sound insulation value of the outer heat-insulating sound-insulating pad of the automobile front wall of prior art is poor, and is made an uproar in engine
The larger vehicle of sound, in-car noise is bigger, therefore the soundproof effect of the heat-insulating sound-insulating pad of prior art, it is impossible to meets people's
Demand.
Utility model content
This application provides heat-insulating sound-insulating pad outside a kind of automobile front wall, preferably to solve heat-insulating sound-insulating outside automobile front wall
Problem.
This application provides heat-insulating sound-insulating pad outside a kind of automobile front wall, including：First nonwoven layer, first non-woven fabrics
Layer lower surface is sequentially provided with the first resin carpet veneer, EVA layer, the second resin carpet veneer and the second nonwoven layer from top to bottom；
The upper surface or lower surface of the EVA layer are provided with pit or projection；
The pit or projection are trapezoidal, taper and/or triangle；
The thickness of the EVA layer is 1-2mm；
The surface density of first nonwoven layer and second nonwoven layer is 80-120g/ ㎡；
The surface density of the first resin carpet veneer and the second resin carpet veneer is 1200-1800g/ ㎡.
From above technical scheme, the outer heat-insulating sound-insulating pad of automobile front wall that the application provides includes the first nothing from top to bottom
Spin layer of cloth, the first resin carpet veneer, EVA layer, the second resin carpet veneer and the second nonwoven layer.The upper surface of the EVA layer or following table
Face is provided with pit or projection, and the pit or projection are trapezoidal, taper and/or triangle.The application employ EVA be used as every
The raw material of sound-absorbing layer, because EVA has the function of shockproof cushioning and sound insulation, the vibrations for automobile front wall metal plate of both having decayed, also increase
The effect of sound insulation.Nonwoven layer had both added sound-absorbing effect or had made that the outer heat-insulating sound-insulating pad in automobile periphery is more attractive, and resin carpet veneer makes
Resin felt can then absorb some EVA layers and not play a part of sound-absorbing every the sound fallen, and double-layer resin felt is then by EVA layer two
The noise absorption of side, it can preferably play the effect of sound-absorbing so that the soundproof effect of the outer heat-insulating sound-insulating pad of automobile front wall is more preferable.
EVA material also has a good effect of heat insulation, therefore the outer heat-insulating sound-insulating pad of automobile front wall that provides of the application is larger improves
The effect of heat insulation of the outer heat-insulating sound-insulating pad of automobile front wall.EVA material also has thermoplasticity good, the advantages of being easy to be molded, therefore this Shen
The outer heat-insulating sound-insulating pad of automobile front wall that please be provided compares the automobile front wall heat-insulating sound-insulating pad of conventionally employed adhesive film material in hardness
It has been lifted that, can preferably be bonded metal plate.
Brief description of the drawings
In order to illustrate more clearly of the technical scheme of the application, letter will be made to the required accompanying drawing used in embodiment below
Singly introduce, it should be apparent that, for those of ordinary skills, without having to pay creative labor,
Other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of the application.
Wherein, the nonwoven layers of 1- first, the first resins of 2- carpet veneer, 3-EVA layers, the second resins of 4- carpet veneer, the nonwovens of 5- second
Layer of cloth；31- pits；32- is raised.
Embodiment
The application preferred embodiment is described in detail below in conjunction with the accompanying drawings, so that the advantages of the application and feature can be more
It is easy to be readily appreciated by one skilled in the art, apparent is clearly defined so as to be made to the protection domain of the application.
The automobile front wall heat-insulating sound-insulating pad that the application provides, including the first non-woven fabrics 1, the following table of the first nonwoven layer 1
Face is sequentially provided with the first resin carpet veneer 2, EVA (ethylene-vinyl acetate copolymer, ethene-vinegar from top to bottom
Sour ethylene copolymer) layer 3, the second resin carpet veneer 4 and the second nonwoven layer 5.
From above technical scheme, the outer heat-insulating sound-insulating pad of automobile front wall that the application provides includes the first nothing from top to bottom
