Abstract
The utility model provides a front wall soundproof pad of automobile, belongs to automobile attachment part technical field. Front wall soundproof pad of automobile comprises PVC superficial layer, XPE intermediate level and cotton felt bottom, PVC superficial layer, XPE intermediate level and cotton felt bottom bond as an organic wholely through heat seal technology, its whole thickness H=15 -20mm. The utility model has the characteristics of soundproof and heat resistant is effectual, light in weight, production simple process, low in manufacturing cost are honest and clean etc, not only more accord with the lightweight of vehicle, economic nature design theory, satisfied the requirement with the whole style uniformity of the indoor decorations of car moreover.
Description
Technical field
The utility model relates to a kind of automotive upholstery, and especially a kind of automobile front wall sound-isolation pad, belongs to car accessories technical field.
Background technology
Automobile front wall sound-isolation pad is installed between automobile engine nacelle and instrument board, and its Main Function is isolation and absorbs the noise and the heat that come from engine, is one of main parts size of improving vehicle NVH performance.
Existing automobile front wall sound-isolation pad is mainly divided into single layer structure or the large class of double layer material composite construction two by its material-structure. Wherein the automobile front wall sound-isolation pad of single layer structure is selected PVC or felt material, and sound-insulating and heat-insulating effect is poor; The automobile front wall sound-isolation pad of double layer material composite construction adopts felt, rubber or EVA Material cladding to form, its combination property promotes to some extent compared with the automobile front wall sound-isolation pad of single layer structure, but the rubber on its top layer or EVA material proportion are larger, cost of goods manufactured is higher, do not meet lightweight, the economy design concept of vehicle, can not meet and the conforming requirement of the indoor decorations whole style of car.
Utility model content
The purpose of this utility model be for prior art to drawback, the automobile front wall sound-isolation pad that a kind of sound-insulating and heat-insulating is effective, can improve vehicle NVH performance is provided.
The utility model above-mentioned purpose is achieved through the following technical solutions:
A kind of automobile front wall sound-isolation pad, is made up of PVC superficial layer, XPE intermediate layer and cotton felt bottom, and described PVC superficial layer, XPE intermediate layer and cotton felt bottom are bonded as one by heat seal process, its integral thickness H=15-20mm.
Above-mentioned automobile front wall sound-isolation pad, described PVC surface layer thickness H1=0.3～1mm.
Above-mentioned automobile front wall sound-isolation pad, described XPE intermediate layer thickness H2=3～5mm.
Above-mentioned automobile front wall sound-isolation pad, described cotton felt underlayer thickness H3=10～15mm.
Automobile front wall sound-isolation pad described in the utility model, adopt the cotton felt three-layer composite structure of PVC+XPE+, utilize cotton felt, sound insulation and acoustical absorbance properties that XPE self is good, reached the object of car compartment and the isolation of enging cabin noise, improved the NVH performance of vehicle; Because cotton felt, XPE are lightweight, be easy to processing, meet light-weighted requirement in addition, reduced production cost; The utility model also can be selected according to the whole style of car body interior trim the PVC surface layer material of different color or pattern simultaneously. In a word, compared with the automobile front wall sound-isolation pad of single layer structure of the prior art or double layer material composite construction, the utlity model has the features such as sound-insulating and heat-insulating is effective, lightweight, production technology is simple, cheap for manufacturing cost, not only more meet lightweight, the economy design concept of vehicle, and met and the conforming requirement of the indoor decorations whole style of car.
Brief description of the drawings
Fig. 1 is automobile front wall sound-isolation pad cutting plane structural representation.
In figure, each list of reference numerals is: 1, PVC superficial layer, 2, XPE intermediate layer, 3, cotton felt bottom.
Detailed description of the invention
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
Referring to Fig. 1, automobile front wall sound-isolation pad described in the utility model is made up of PVC superficial layer 1, XPE intermediate layer 2 and cotton felt bottom 3, described PVC superficial layer 1, XPE intermediate layer 2 and cotton felt bottom 3 are bonded as one by heat seal process, described PVC surface layer thickness H1=0.3～1mm, described XPE intermediate layer thickness H2=3～5mm, described cotton felt underlayer thickness H3=10～15mm, density γ=800～1000g/m2, the integral thickness H=15-20mm of automobile front wall sound-isolation pad.
Referring to Fig. 1, automobile front wall sound-isolation pad described in the utility model has adopted the cotton felt three-layer composite structure of PVC+XPE+, utilize cotton felt, sound insulation and acoustical absorbance properties that XPE self is good, reached the object of car compartment and the isolation of enging cabin noise, improved the NVH performance of vehicle; Because cotton felt, XPE material weight are light, be easy to processing, meet light-weighted requirement in addition, reduced production cost; The utility model also can be selected according to the whole style of car body interior trim the material of the PVC superficial layer 1 of different color or pattern simultaneously.
