It is general to be handled using waste fiber through shredding, then after random web-laying equipment networking, form omnidirectional mixed and disorderly web, web
Close and fluffy felt material is formed after vulcanization hot rolling is reinforced, then the material formed is bonded by this two layers of felt material, melting is utilized
Fiber is thermally bonded or applied the bonding of phenolic resin additive and reinforces, the function with sound absorption and sound insulation.Due to waste spinning fibrofelt
Two layers of different densities felt material between there is air layer, air layer is flexible, rise cushioning effect, resonance can be reduced, suction
Quiet down sound emittance, and improves the absorption of material, therefore waste spinning fibrofelt is often widely used to do with automotive interior and inhaled
Sound insulation is used.
The raw material for the waste spinning fiber sound-insulating and heat-insulating felt that prior art is used are mainly waste spinning cotton and phenolic resin, waste spinning cotton
It is that leftover pieces, leftover bits and pieces, waste silk for being produced in the production process such as textile mills, clothing factory in textile industry etc. are upset after mixing again
Formed, main component is organic fibrous material, is asked while interiors of products contains the health such as substantial amounts of bacterium, dust, pollutant
Topic, easily produces and goes mouldy, smell is pungent, serious emission problem is had for automotive interior, threaten the health and safety of operator；
Simultaneously phenolic resin as a kind of polymeric additive of chemical synthesis can be produced in use and production process a large amount of smog and
Pernicious gas, can equally cause serious pollution problem.Thickness, the rigidity of parts needs of parts design are additionally based on,
The universal surface density of material therefor concentrates on 1000g-2000g/ ㎡, and pts wt is laid particular stress on, and is not suitable with the concept of lightweight automobile.
Utility model content
The purpose of this utility model is to provide a kind of sound-heat insulated cushion of automobile engine nacelle front wall, to solve prior art
The sound-heat insulated cushion of middle automobile engine nacelle front wall, which is easily produced, to go mouldy, the pungent technical problem of smell.
To achieve the above object, the technical solution of the utility model is：
A kind of sound-heat insulated cushion of automobile engine nacelle front wall of the present utility model, including multi-density inhale sound proof part, heat-insulated
Portion, the multi-density is inhaled sound proof part and is attached on the insulation part, and it is three layers that the multi-density, which inhales sound proof part, and centre is lightweight
Foaming layer, the light-weight foam layer both sides are non-woven fabrics flow resistance layer；The insulation part is diffusing reflection micropore thermal insulation layer；It is described unrestrained anti-
Micropore thermal insulation layer is penetrated to be molded together in one by hot press with non-woven fabrics flow resistance layer.
Further improvement is that, light-weight foam layer be in polyurethane, ethylene propylene diene rubber or melamine wherein
It is a kind of.
Further improvement is that, the non-woven fabrics flow resistance layer is the one of which in polyester, polypropylene, polyamide, described
The grammes per square metre of non-woven fabrics flow resistance layer is 30-120g/m2, thickness is 0.5-2mm.
Further improvement is that, the light-weight foam layer passes through powdery, fibre web shape or membranaceous with non-woven fabrics flow resistance layer
Hot melt adhesive it is gluing together in one.
Further improvement is that, the diffusing reflection micropore thermal insulation layer is the aluminium foil of surface irregularity, the aluminium foil surface
Micropore is uniformly provided with, the aperture of micropore is 0.1-1.5mm, and the punching rate of the aluminium foil is 5%-15%.
Compared with prior art, the sound-heat insulated cushion of automobile engine nacelle front wall of the present utility model, is inhaled by multi-density
Sound proof part is set to the structure of non-woven wraps light-weight foam layer, not including natural fibers and phenolic resin class curing agent, is difficult production
Mildew change, meanwhile, nuisance and volatile organic content are very low, and no sharp aroma is produced, and VOC content is from 300-500ugC/g
20-150ugC/g can be reduced to, oder levels are reduced to 3.0 from 5.0；In addition, being tied using non-woven wraps light-weight foam layer
The frame mode of aluminium foil is closed, part grammes per square metre is reduced to 300-500g/ ㎡ from 1500-2000g/ ㎡, significantly reduces product
Weight, be conducive to the concept of automotive light weight technology.
