Description
Technical field
The present invention relates to a kind of material of automobile heat insulation sound panel and preparation method thereof.
Background technology
Heat-barrier material (thermal insulation material), can block the material of hot-fluid transmission, also known as heat insulation
Material.Conventional insulation material, such as glass fibre, asbestos, rock wool, silicate, heat-insulation material, such as aerogel blanket, vacuum
Plate etc..Heat-barrier material is divided into porous material, heat-reflecting material and the class of vacuum material three.The former is using material hole contained in itself
It is heat-insulated, because the thermal conductivity factor of the air or inert gas in space is very low, such as foamed material, fibrous material；Heat reflection material
Material has reflectance factor very high, can reflect away heat, such as polyester, the polyimides of gold, silver, nickel, aluminium foil or plating metal
Film etc..Vacuum heat insulation materials are to reach obstruct convection current come heat-insulated using the inner vacuum of material.Aerospace industry is to used
The weight and volume requirement of heat-barrier material is more harsh, requires that it has the performances such as sound insulation, vibration damping, anticorrosion concurrently toward contact.It is various
Aircraft to heat-barrier material the need for be not quite similar.Foamed plastics, super glass wool, silicon high are commonly used in aircraft cockpit and driving cabin
Oxygen cotton, vacuum insulation panel come heat-insulated.The heat-barrier material of nose of missile is in early days phenolic foam, is gathered as temperature tolerance is good
The application of urethane foamed plastics, and single heat-barrier material is developed into sandwich.The heat-insulated mode of guided missile instrument room be
The foamed coating of a number of plies millimeters thick is applied on nacelle exterior skin, at normal temperatures as erosion shield, when Aerodynamic Heating reaches 200
When more than DEG C, just even foaming and rise heat-blocking action.Artificial earth satellite is moved in high temperature, the environment of low temperature alternation, palpus
Using the multilayer insulation material of high reflectivity energy, usually by tens layers metallized film, aluminized mylar, polyimides of aluminizing
Film is constituted.In addition, surface thermal insulation tile succeeds in developing the heat-insulating problem for solving space shuttle, while also indicate heat-insulated material
Expect the higher level of development.
Acoustic material is to refer to block sound transmission or weaken a class material, component or the structure of transmission acoustic energy, and it is special
It is that heavier mass density is higher to levy, such as steel plate, stereotype, concrete walls, brick wall.Sound insulation refer to by certain article sound or
Noise insulati on, cut-off, separation etc., therefore it is accomplished by acoustic material.The incident acoustic energy of material side and the transmission acoustic energy of opposite side
Related decibels are exactly the sound transmission loss of the material, are generally represented with symbol R (dB).Acoustic material or component, can be because using field
The soundproof effect for closing difference, method of testing difference and drawing is different.For acoustic material, to weaken transmission acoustic energy, stop sound
Propagation, cannot be porous as sound-absorbing material, loose, ventilative, opposite its material should be weight and closely knit, such as steel
The class material of plate, stereotype, brick wall etc. one.The requirement of acoustic material material is closely knit imporosity or gap；There is larger weight.Due to
This kind of acoustic material is closely knit, it is difficult to which absorbing and reflected through acoustic energy can be strong, so its sound absorption qualities are poor.Acoustic material can make
Transmission sound energy attenuation is expressed, the metering side of its sound transmission loss decibel for convenience to 10-3~10-4 times or smaller of incident acoustic energy
Method is represented.
