Heat insulating mattress is built in a kind of narrow health check-up
Technical field
The utility model relates to automotive trim field, is specifically related to a kind of narrow health check-up and builds heat insulating mattress.
Background technology
Heat insulation cushion for front car body, is arranged at automobile predecessor, plays the effect of heat insulation noise elimination, therefore generally need to use material heat insulation and that sound-absorbing effect is good to make.Due to the exploration in automotive trim market, material category that at present heat insulating mattress uses is various, dragons and fishes jumbled together, common common interior material on market, easily contain harmful substance or produce pungent smell, be placed in for a long time the space of relative closure, can bring certain pollution to environment, also can produce certain injury to human body simultaneously, heat insulating mattress on common market, its soundproof effect is poor, can not effectively reduce automobile noise originally.
Now, China is electric, the production of electronic equipment interior trim parts, all require to reach the RoHS of European Union environment-protecting asepsis standard and the certification of CCC China Compulsory, and requirement has good soundproof effect, require interior products to there is the harmful substance compositions such as lower smell, formaldehyde still less, there is better anti-noise soundproof effect simultaneously.
Utility model content
For above problems of the prior art, the utility model provides a kind of heat-proof quality and the good narrow health check-up of one of sound insulation value to repair heat insulating mattress.
The utility model is achieved through the following technical solutions:
Heat insulating mattress is built in a kind of narrow health check-up, and described narrow health check-up is repaiied heat insulating mattress and formed by four layer materials are compound, and the superiors are the cotton layer of phenolic resins, and the second layer is EVA layer, the 3rd layer of nonwoven layer, and the 4th layer is aluminium foil layer.
Described phenolic resins cotton layer thickness is 4mm, and described EVA layer thickness is 3mm, and described nonwoven layer thickness is 1.5mm, and described aluminium foil layer thickness is 0.2mm.
Described heat insulating mattress is by hot-forming.
For making the utility model reach the effect of marketing, the material adopting all can be buied by market.Wherein EVA is ethylene-vinyl acetate copolymer.
The beneficial effects of the utility model are: utilize EVA layer to have good chemical stability, ageing-resistant, ozone resistance, the higher mechanical strength of phenolic resins cotton, good insulating properties, heat-resisting, corrosion resistant characteristic, nonwoven protection against the tide, ventilative, pliable and tough, light weight, the characteristic such as not combustion-supporting, in conjunction with the plasticity of aluminium foil, high temperature resistant, oil resistivity, above each material is passed through hot-forming, can better reach heat insulation and effect sound insulation, make its thermal insulation and sound-proofing effect promoting 50%, it is placed in to Zhai Ti maintenance department, effectively improve the solemn silence of entirety in automobile and reduced the temperature in car.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure: 1 is the cotton layer of phenolic resins; 2 is EVA layer; 3 is nonwoven layer; 4 is aluminium foil layer.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further details.
The utility model provides a kind of narrow health check-up to build heat insulating mattress, and as shown in Figure 1, narrow health check-up is repaiied heat insulating mattress and formed by four layer materials are compound, and the superiors are the cotton layer 1 of phenolic resins, and the second layer is that 3, the four layers of 2, the three layers of nonwoven layer of EVA layer are aluminium foil layer 4.Wherein the thickness of the cotton layer 1 of phenolic resins is 4mm, and the thickness of EVA layer 2 is 3mm, and the thickness of described nonwoven layer 3 is 1.5mm, and the thickness of described aluminium foil layer 4 is 0.2mm.Wherein heat insulating mattress is by hot-forming.
For making the utility model reach the effect of marketing, the material adopting all can be buied by market.Wherein EVA is ethylene-vinyl acetate copolymer.
Above detailed description of the invention has been described in detail essence of the present utility model, but can not limit protection domain of the present utility model with this.Apparently, under the enlightenment of the utility model essence, the art those of ordinary skill also can carry out many improvement and modification, within it should be noted that these improvement and modification all drop on claim protection domain of the present utility model.
The utility model utilizes EVA layer to have good chemical stability, ageing-resistant, ozone resistance, the higher mechanical strength of phenolic resins cotton, good insulating properties, heat-resisting, corrosion resistant characteristic, nonwoven protection against the tide, ventilative, pliable and tough, light weight, the characteristic such as not combustion-supporting, in conjunction with the plasticity of aluminium foil, high temperature resistant, oil resistivity, above each material is passed through hot-forming, can better reach heat insulation and effect sound insulation, make its thermal insulation and sound-proofing effect promoting 50%, it is placed in to Zhai Ti maintenance department, effectively improve the solemn silence of entirety in automobile and reduced the temperature in car, meet the RoHS of European Union environment-protecting asepsis standard and the certification of CCC China Compulsory, be worth of widely use.
