Abstract
The utility model discloses an enclose amortization heat insulating mattress before automotive interior, including aluminium foil layer, PP twoly cover the cloth layer, the cotton layer of sound is inhaled to two ingredient, two ingredients are inhaled the cotton layer both sides of sound and are PP is two to cover the cloth layer, three -layer hot briquetting, the aluminium foil layer sets up starts the machine side in being close to the two cloth layer surface of covering of PP form the four -layer structure, two ingredients are inhaled the cotton layer of sound and for PETPP blend composition, inside is latticed, are had the gas pocket. The utility model has the advantages that: the shape is fixed, the sound construction, have certain intensity, has fine sound insulation, inhales the sound, thermal -insulated effect to through aluminium foil layer promotion radiating effect, though enclose thermal -insulated radiating problem well before having solved well.
Description
Technical field
This utility model relates to a kind of automotive trim front wall sound deadening heat insulation pad.
Background technology
Automotive trim front wall sound deadening heat insulation pad refers to the dividing plate between engine nacelle and compartment, and it and floor, front column connect, for preventing high temperature in engine nacelle, noise from scurrying into compartment, and its sound insulation to be had, sound-absorbing, heat insulation effect.The material of automobile front wall is uneven in the market, mainly use felt, nonwoven cloth material, the front wall that this material is made can not effectively sound insulation, sound-absorbing, heat insulation, though or heat insulation can not effectively dispel the heat, have impact on the complete vehicle quality of automobile, bring hidden danger the most also to the safety of driver and crew.
Utility model content
Utility model purpose: for the problems referred to above, the purpose of this utility model be to provide a kind of can effectively sound insulation, sound-absorbing, heat insulation, heat radiation automotive trim front wall sound deadening heat insulation pad.
Technical scheme: a kind of automotive trim front wall sound deadening heat insulation pad, including aluminium foil layer, PP is double covers layer of cloth, double-component acoustical cotton layer, described double-component acoustical cotton layer both sides are described PP pair and cover layer of cloth, three layers hot-forming, described aluminium foil layer is disposed in proximity to the double layer of cloth surface of covering of described PP of engine side, formation four-layer structure；Described double-component acoustical cotton layer is PET/PP blend composition, and inside is latticed, has pore.
Beneficial effect: compared with prior art, the utility model has the advantages that: shape is fixed, sound construction, have certain intensity, there is good sound insulation, sound-absorbing, effect of heat insulation, and by aluminium foil layer improving radiating effect, though solve that front wall is heat insulation well but the problem that can not dispel the heat well.
Accompanying drawing explanation
Accompanying drawing is this utility model layer structure schematic diagram.
Detailed description of the invention
Below in conjunction with the accompanying drawings and specific embodiment, it is further elucidated with this utility model, it should be understood that these embodiments are merely to illustrate this utility model rather than limit scope of the present utility model, after having read this utility model, those skilled in the art all fall within the application claims limited range to the amendment of the various equivalent form of values of the present utility model.
As shown in drawings, a kind of automotive trim front wall sound deadening heat insulation pad, including aluminium foil layer 1, double layer of cloth 2, the double-component acoustical cotton layer 3 of covering of PP, form four layers of composite construction from top to bottom: aluminium foil layer 1, PP be double covers layer of cloth 2, double-component acoustical cotton layer 3, PP is double covers layer of cloth 2.
Double-component acoustical cotton layer is PET/PP blend composition, is made into latticed, internal fluffy, has a large amount of pore, remarkably productive at sound-absorbing and heat insulation aspect, additionally also added a large amount of fire retardant, and flame retardant effect highlights.The double feature covering cloth of PP is that after heating cools down, fixed effect is good, double-component acoustical cotton layer is double with the PP of its both sides covers layer of cloth, and three layers, after hot-forming cooling, can well be bonded together, and there is fixing shape and certain intensity, solve sound insulation, sound-absorbing, heat insulation problem well.
In the past poor due to radiating effect, after automobilism a period of time, front wall is near the place of electromotor, owing to high temperature occurs in that the change of color, bring hidden danger to the safety of the driver and crew of automobile, for solving this problem, before front wall hot pressing, covering layer of cloth surface and adding aluminium foil layer near the PP of engine side is double, which increasing radiating effect, though well solving the heat insulation problem that can not dispel the heat very well of front wall.
Claims (1)
