Description
Technical field
The utility model relates to a kind of sound-heat insulated cushion, particularly relates to a kind of automobile and uses the sound-insulating and heat-insulating liner.
Background technology
As everyone knows, general sound-heat insulated cushion adopts fiber-like material mostly at present, the intermediate layer that perhaps forms with felt, imitative felt; Though this type material effect of heat insulation or soundproof effect are good, the heat resistance of felt, imitative felt structure sheaf is bad, under hot environment, uses for a long time; The material destruction with physical arrangement that can deform had a strong impact on the soundproof effect of sound-heat insulated cushion, and some material (like glass fibre) feature of environmental protection is poor; Grammes per square metre is big, and soundproof effect is undesirable.
Open day is on March 15th, 2006; Publication number is that the Chinese patent document of CN 2764669Y discloses a kind of compound noise reduction thermal insulation protection pad; Be to form the top layer by nonwoven, porous aluminium foil, there are felt, imitative felt in the intermediate layer, sticks with glue a kind of neonychium that the fixing bonding of agent forms to each other; Its weak point is that this structure is worked in the environment of long term high temperature; Adhesive lost efficacy easily, and felt, imitative felt deform and the destruction of physical arrangement easily, thereby had had a strong impact on the sound isolating and heat insulating performance of this neonychium.
Summary of the invention
The purpose of the utility model is the problem that the feature of environmental protection is poor, grammes per square metre is big, hear resistance is bad and soundproof effect is not good that exists for the sound-heat insulated cushion that solves prior art, provides the automobile that a kind of sound absorbing capabilities is good, heat resistance stable, the feature of environmental protection is good, grammes per square metre is little and be easy to make to use the sound-insulating and heat-insulating liner.
The utility model is achieved through following technical proposals; A kind of automobile is used the sound-insulating and heat-insulating liner, and said automobile uses the sound-insulating and heat-insulating liner to be sandwich construction, and its upper surface is the porous aluminium foil layer; The porous aluminium foil layer is the melamine foamed resin layer down; For being provided with the low-density polyurethane layer of aluminium foil, the lower surface of liner is a nonwoven layer to the melamine foamed resin layer, is provided with the articulamentum of melting structure between the adjacent two layers down.The low-density polyurethane material is lighter than traditional fibrous material, and grammes per square metre is little, in the low-density polyurethane material, is provided with aluminium foil; When promoting the material heat-proof quality, material is strengthened for the absorbability of medium and low frequency noise, improved the relatively poor shortcoming of traditional fibre material medium and low frequency noise absorbability; Material has anti-flammability in addition; Do not contain glass fibre, chafe not, the feature of environmental protection is good; The melamine foamed resin layer mainly act as sound-absorbing; The loose structure of material helps the absorption to noise; Compare with traditional blown polyurethane materials; The heat resistance of melamine material is better, especially at high temperature keeps the sound insulation capabilities of material strong, and the grammes per square metre of material is much smaller than the grammes per square metre of polyurethane; In addition, melamine foamed resin material and low-density polyurethane material fit are used, because there is the difference of density in two kinds of materials, have formed density gradient, have further strengthened the ability of noise reduction; The porous aluminium foil layer is a heat resistant layer, utilizes aluminium foil that heat radiation is had high reflected refraction rate, thereby plays good resistance heat effect, and the space in the aluminium foil layer also helps absorption and consumption to acoustic energy, therefore simultaneously with good noise reduction; The articulamentum of melting structure forms through heat fusing, has replaced adhesive layer; Owing to do not use adhesive, reduced operation, avoided pollution or the harm healthy of toxicity that adhesive possibly contain or hypotoxicity to the producer to environment; Environmental protection is friendly, and under hot environment, is difficult for losing efficacy, simultaneously can hot compression molding; Make simply, be easy to the scale low-cost production.
As preferably, described nonwoven layer thickness is 0.4 millimeter to 0.6 millimeter, grammes per square metre be 60 grams/square metre to 80 grams/square metre.
As preferably, the thickness of described low-density polyurethane layer is 8 millimeters to 10 millimeters, and density is 13 kilograms/cubic metre to 17 kilograms/cubic metre.Compare with conventional glass fiber-like material (density is generally all greater than 40 kilograms/cubic metre), under the situation of equal volume, can alleviate nearly half the weight, weight loss effect is obvious.
As preferably, be provided with aluminium foil in the described low-density polyurethane layer, aluminium foil is a loose structure.The inside of low-density polyurethane layer is provided with the aluminium foil of porous, when promoting the material heat-proof quality, material is strengthened for the absorbability of medium and low frequency noise, has improved the relatively poor shortcoming of traditional fibre material medium and low frequency noise absorbability.
As preferably, the thickness of described melamine foamed resin layer is 8 millimeters to 10 millimeters, and density is 8 kilograms/cubic metre to 10 kilograms/cubic metre.Compare with traditional blown polyurethane materials (density is generally all greater than 30 kilograms/cubic metre), under the situation of equal volume, can alleviate nearly 2/3rds weight, weight loss effect is obvious.
As preferably, the thickness of porous aluminium foil layer is 0.8 millimeter to 1 millimeter, and the density in hole is 70/square centimeter to 80/square centimeter.Consider the resistance thermal effect, take into account sound insulation and bulk strength simultaneously, the density in preferred hole is in this scope, and the porous aluminium foil layer can be obtained best sound-insulating and heat-insulating effect.
As preferably, the thickness of the articulamentum of melting structure is 0.1 millimeter to 0.2 millimeter.Choosing thick layer in this scope, mainly is intensity and the manufacturing cost of taking into account melting layer, and the thickness of fusion articulamentum is thick partially, though adhesion strength is high, and long processing time, manufacturing cost height; The thickness of fusion articulamentum is thin partially, though shorten process time, manufacturing cost reduces, adhesion strength reduces, and melting layer lost efficacy easily.
The beneficial effect of the utility model is: it has solved the problem that the feature of environmental protection is poor, grammes per square metre is big, hear resistance is bad and soundproof effect is not good that the prior art sound-heat insulated cushion exists effectively; The utility model sound absorbing capabilities is good, heat resistance stable, the feature of environmental protection is good, grammes per square metre is little and be easy to manufacturing, has good practical value.
