Description
Technical field
The utility model is to be related to a kind of noise reduction heat-insulating composite panel, is specifically related to a kind of automobile ceiling that is applicable to
Bireflectance noise reduction heat-insulating composite panel, belongs to automobile heat insulation technical field.
Background technology
With the fast development of social science and technology, people are also higher and higher to the performance requirement of automobile, such as：Automobile it is heat-insulated
Property, noise reduction etc..The thermal insulation of automobile and it is noise reduction seriously affected automobile comforts of use, if the thermal insulation of automobile compared with
Difference, then during the broiling summer, the heat outside vehicle is transmitted to car and vehicle interior temperature is caused to increase rapidly quickly, not only serious shadow
The comfort of automobile is rung it is also possible to being had some impact on to safe driving；On the contrary, in cold winter, interior heat is quickly
It is transmitted to outside vehicle, it usually needs opening air-conditioning for a long time can just make interior temperature maintain certain preference temperature, air-conditioning
Long-time open, inevitably cause the waste of the energy and the destruction of environment.Meanwhile if automobile it is noise reduction poor,
In use, noise is larger for automobile, inevitably generates noise pollution, seriously affects the physical and mental health of people.Therefore, on automobile
It is generally necessary to which the flowing of heat can also be inhibited while using inhibition noise, vehicle interior temperature is enable to keep the drop of certain stability
It makes an uproar heat-barrier material, to improve automobile comforts of use.
And the traditional noise reducing heat insulating used in automotive field, typically glass fibre class, asbestos friction material class, felt
The homogenous materials such as class, ceramic-like, polyester foamed plate, aluminium foil class, noise reduction heat insulation is general, and the noise reduction that cannot meet automobile is heat-insulated
Use demand.
In order to further increase the noise reduction heat-proof quality of automobile, begin to use compound noise-reducing heat-barrier material on automobile at present.
Common compound noise-reducing heat-barrier material includes mainly following several on automobile at present：

It is widely used in auto industry by foreign countries, light GMT structure is followed successively by fabric, glued membrane, semi-finished product, glued membrane, nothing from top to bottom
Woven fabric, since the features such as its intensity is high, and sound absorption qualities are good, and moldability is superior, recoverable is widely used in automobile
Inner decorative ceiling, door partition board, noise isolation cover and luggage carrier etc.；Although light GMT structure have the advantages that it is above-mentioned, it is whole multiple
The thermal coefficient of condensation material is higher, and heat-proof quality is short of；
2) glass/polyurethane (PU) foam composite material：The composite material is mainly used for roof of the vehicle, composite material master
It to be made of decorative layer and base material, by hot pressing mode composite molding, for wherein decorative layer towards passenger, common used material is knitted side
Material, non-woven fabrics, PVC etc.；Base material can be divided into PU foamed boards, PP fiberboards and hemp fibre board etc., and wherein PU foamed boards are not only resistance to
Warm, mould proof, intensity etc. meet the Essential Performance Requirements of roof of the vehicle, and have more than flaxen fiber type, PP fiber templates
The performance of well heat-insulated, sound-absorbing etc. is more universal in roof of the vehicle use；Although this composite material have preferably every
Hot property, but be only simply to be superimposed the relatively low material of some thermal coefficients, overall heat-proof quality is still
Shortcoming, and absorbing sound and lowering noise performance is weaker；
3) aluminum foil composite：This composite material mainly carries out aluminium-foil paper or cloth with other heat-insulation noise-reduction materials
It is compound, such as：Include foaming rubber plastic material layer, layer of polyurethane, fiberglass aluminum foil cloth (patent CN201020505588.3) successively
Composite material；It is answered successively by high temperature bonding by aluminium foil layer, glass fiber layer of cloth and fire-retardant acetic acid modified poly ethylene foamed material layer
The composite material (patent CN201420210129.0) being integrated；Successively by single layer aluminium foil, PE film layers and semi-solid preparation carpet veneer
The composite material (patent CN201420460064.5) of composition；Successively by nonwoven layer, netted aluminium foil layer, bamboo, anti-
The composite material (patent CN201621024784.2) etc. of ultraviolet precoat composition.Above-mentioned composite material mainly will have sound-absorbing
The foamed material or cloth of decrease of noise functions carry out compound with the smaller or aluminium foil with reflex of thermal coefficient so that formation
Composite material has noise reduction heat-proof quality, and still, above-mentioned composite material, which remains, is simply superimposed a variety of materials, material
Whole noise reduction heat-proof quality is also short of, and cannot be satisfied the use demand very well.
