Abstract
The utility model relates to a novel sound-insulation and heat-insulation pad for an automobile engine cabin, which has good sound-insulation and heat-insulation effect and has a multi-layer composite structure formed by a plurality of materials; the novel sound-insulation and heat-insulation pad comprises a pad body, the surface of the pad body is provided with an aluminium foil layer, the middle of the pad body is a main layer, the main layer has a three-layer structure, and the bottom of the pad body is provided with non-woven fabric. The main layer of the sound-insulation and heat-insulation pad has the three-layer structure, the three layers of structure respectively adopt three different materials, and the three layers of materials are jointly matched to achieve the effects of reducing vibration noise and absorbing and insulating noise of an engine. Two sides of the main material respectively adopt the non-woven fabric and the metal aluminium foil, and the application of the metal aluminium foil material replaces a layer of non-woven fabric, so that the whole pad has more excellent heat-insulation performance.
Description
Technical field
The utility model relates to a kind of cushions, particularly relates to a kind of new automobile enging cabin sound-heat insulated cushion.
Background technology
As everyone knows, general auto sound-insulating and thermal-insulating pad mostly is mineral wool or regeneration cotton goods greatly, though also can play certain sound insulation and effect of heat insulation,, its structure is single, and sound insulation and effect of heat insulation are all not ideal enough.
Patent Office of the People's Republic of China disclosed the utility model that a kind of name is called the automobile heat insulation sound-absorbing pad on January 27th, 2010, and its notification number is CN201390215Y.This patent disclosure a kind of automobile heat insulation sound-absorbing pad, comprise pad, described pad surface is provided with aluminium foil layer, pad middle part is provided with the lightweight sponge, is laid with grid cloth between described aluminium foil layer and the lightweight sponge, is provided with nonwoven bottom the pad.This utility model is simple in structure, with low cost, and its weak point is that the pad material of main part is single, can not play good sound-insulating and heat-insulating effect.
Summary of the invention
The material of main part that the purpose of this utility model is to solve auto sound-insulating and thermal-insulating pad in the prior art is comparatively single, can not play the problem of good sound-insulating and heat-insulating effect, a kind of new automobile enging cabin sound-heat insulated cushion that the multiple material of utilizing of good sound-insulating and heat-insulating effect is formed multi-layer compound structure that has is provided.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of new automobile enging cabin sound-heat insulated cushion, comprise pad, described pad surface is provided with aluminium foil layer, and described pad middle part is a body layer, and described pad bottom is provided with basic thermal insulation layer.The utility model body layer is a sandwich construction, and every layer of structure all adopts different materials, and common cooperation of layers of material reaches the vibration damping of engine luggine noise and the effect of sound-absorbing sound insulation.The material of main part both sides are respectively nonwoven and metal aluminum foil, and the application of metal aluminum foil material has replaced layer of non-woven fabric, make unitary pad have more excellent heat-proof quality.
As preferably, described body layer is a three-decker, and for being added with the butyl rubber layer of metal dust, described butyl rubber layer both sides are glass layer in the middle of the described body layer.The butyl rubber material clip is between the layer glass fibrous material, and common cooperation of trilaminate material reaches the vibration damping of engine luggine noise and the effect of sound-absorbing sound insulation.
As preferably, be low grammes per square metre glass layer between described butyl rubber layer and the aluminium foil layer.Mainly play absorption to engine noise.
As preferably, between described butyl rubber layer and the basic thermal insulation layer high grammes per square metre glass layer.Mainly play the sound insulation effect of noise to external world.
As preferably, fixing between described each layer of new automobile enging cabin sound-heat insulated cushion by bonding, make and play good cooperation between each layer structure.
The utility model is by the fit applications of height grammes per square metre glass fiber material, form the grammes per square metre gradient, increased the flow resistance of sound wave by integral material, further promoted the sound insulation property of material, material of main part adopts sound-absorbing-sound insulation-sound-insulating structure, brought into play good acoustical behavior, added the heat-proof quality of aluminum foil material, make whole sound-heat insulated cushion embodiment excellent comprehensive performances.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model;
Among the figure: 1. aluminium foil layer, 2. low grammes per square metre glass layer, 3. butyl rubber layer, 4. high grammes per square metre glass layer, 5. basic thermal insulation layer.
The specific embodiment
Also in conjunction with the accompanying drawings the utility model is further specified below by specific embodiment.
A kind of new automobile enging cabin sound-heat insulated cushion (as shown in Figure 1), comprise pad, described pad surface is an aluminium foil layer 1, thickness is 0.8mm, the heat that aluminium foil layer 1 will distribute in the time of will directly contacting engine operation, aluminium foil layer 1 is owing to itself have good heat-blocking action, can completely cut off heat well, the heat that is delivered to the crew module is reduced, described pad lower surface is basic thermal insulation layer 5, the layer structure that described basic thermal insulation layer 5 is made for nonwoven, described pad middle part is a body layer, and described body layer is a three-decker, is the butyl rubber layer 3 that is added with metal dust in the middle of the described body layer, described butyl rubber layer 3 thickness are 1.5mm～3mm, and density is 1.6g/cm
3, described butyl rubber layer 3 both sides are glass layer, are low grammes per square metre glass layer 2 between described butyl rubber layer 3 and the aluminium foil layer 1, and described low grammes per square metre glass layer 2 is made by low grammes per square metre glass fibre, and grammes per square metre is 600g/m
2Below, thickness is 5mm～10mm, is high grammes per square metre glass layer 4 between described butyl rubber layer 3 and the basic thermal insulation layer 5, and described high grammes per square metre glass layer 4 is made by high grammes per square metre glass fibre, and grammes per square metre is 800g/m
2More than, thickness is 5mm～10mm, and is fixing by bonding between described each layer of new automobile enging cabin sound-heat insulated cushion.Whole sound-heat insulated cushion can be fitted by buckle and panel beating at enging cabin cover, the preceding panel beating outside, the front deck water guide mainboard position of enclosing, and is simple and easy to use; As compound sound-insulating and heat-insulating liner, it can reduce the vibration and the noise of car load to large extent from the material angle, and isolated enging cabin is delivered to crew module's heat, promotes the sound isolating and heat insulating performance of car load.
Above-described embodiment is a kind of preferable scheme of the present utility model, is not that the utility model is done any pro forma restriction, also has other variant and remodeling under the prerequisite that does not exceed the technical scheme that claim puts down in writing.
