Abstract
The utility model provides an automobile front part noise reduction pad which is formed by composition of three layers of materials, wherein the upper layer is EVA plastic foaming material, the interface layer is regenerated fibre cotton, and the lower layer is PET, wherein the PET is polyethylene glycol terephthalate. The noise reduction pad adopts the advantages of good buffering, anti-damping, heat insulation and moistureproof of the EVA and the characteristics of sound absorption and sound insulation of the regenerated fibre cotton, and combines the high impact resistance strength and excellent high and low temperature resistance property of the PET, therefore, the compounded automobile front part noise reduction pad has better effects of sound absorption, sound insulation and anti-damping.
Description
Technical field
The utility model relates to the automotive trim field, is specifically related to enclose silencing pad before a kind of automobile.
Background technology
Enclose silencing pad before the automobile, enclose vehicle body before being used to wrap automobile, play the effect of shock-absorbing and noise-eliminating, so generally need to use damping and the good material of sound-absorbing effect to process.Because the opening in automotive trim market; The employed material category of silencing pad is various at present, dragons and fishes jumbled together; Common common interior material on the market is prone to contain objectionable impurities or produces pungent smell, places the space of relative closure for a long time; Can bring certain pollution to environment, also can produce certain injury to human body simultaneously.
The utility model content
To the problem that exists in the above prior art, the utility model encloses silencing pad before the effective automobile of a kind of damping and silencing is provided.
The utility model is realized through following technical scheme:
Enclose silencing pad before the automobile, said silencing pad constitutes by trilaminate material is compound, and it is the EVA plastic foam material at the middle and upper levels, and interlayer is that regenerated fibre is cotton, and lower floor is PET, and wherein PET is a polyethylene terephthalate.
Said silencing pad is through compression molding.
For making the utility model reach the effect of marketing, the material that is adopted all can be buied by market.
The beneficial effect of the utility model is: utilize advantages such as the good buffering of EVA, antidetonation, heat insulation, protection against the tide; And the characteristic of the cotton sound-absorbing sound insulation of regenerated fibre; In conjunction with high, the good high and low temperature resistance of PET impact strength; Enclose silencing pad before the automobile that is composited, have the effect of better sound-absorbing, sound insulation and anti-damping.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1 is the EVA plastics foam bed of material; 2 is the cotton layer of regenerated fibre; 3 is pet layer.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is explained further details.
The utility model encloses silencing pad before a kind of automobile is provided, and is compound through compression molding by trilaminate material, and it is EVA plastic foam material 1 at the middle and upper levels, and interlayer is a regenerated fibre cotton 2, and lower floor is a pet layer 3, and wherein PET is a polyethylene terephthalate.For making the utility model reach the effect of marketing, the material that is adopted all can be buied by market.
The utility model utilization utilizes advantages such as the good buffering of EVA plastic foam material 1, antidetonation, heat insulation, protection against the tide; And the characteristic of the cotton 2 sound-absorbing sound insulations of regenerated fibre; In conjunction with high, the good high and low temperature resistance of PET3 impact strength, enclose silencing pad before the automobile that is composited, have the effect of better sound-absorbing, sound insulation and anti-damping; Meet the RoHS of European Union environment-protecting asepsis standard and CCC China mark of safety certification, be worth of widely use.
