Description

A kind of multilayer materials of high ferro bullet train floor
Technical field
Patent of the present invention relates to a kind of multilayer materials, particularly relates to the multilayer materials of a kind of high ferro bullet train floor.
Technical background
Along with China's the leading of go-global strategy, China has started to enter the high ferro epoch, high ferro motor-car brings fast, While safe, comfortable, the harm such as environmental pollution noise and vibration are also brought, along with noise limit value mark in passenger car Accurate progressively improvement, noise problem becomes more and more important, and internal car noise is not only the forced examination requirement that passenger vehicle dispatches from the factory, and is also outlet car One of Compulsory Feature project meeting Foreign certification, it may be said that control internal car noise and be not only the protection to passenger, especially visitor How the important embodiment of car manufacture level, control the noise in car, and improving the intensity of flooring material is the primary of our research at present Problem.
Traditional vehicle interior floor typically uses laminated structure, is one layer of colloid floor cloth of covering on plywood caul, This floor panel structure can not meet the requirement that passenger is the highest to vehicle environment in terms of vision and comfort level the most, additionally along with The continuous speed-raising of high ferro motor-car, vibration and noise when vehicle runs constantly aggravate, coupling condition relatively before rolling stock more Complexity, produced noise when existing flooring material can not preferably stop vibration and the vehicle operation of car body external equipment, institute To need the sound insulation value using the more preferable Sound insulation floorings of soundproof effect to improve vehicle.Meanwhile, the constantly speed-raising of high ferro motor-car is right The intensity of flooring material proposes higher intensity and bearing requirements.
The Chinese utility model patent of Application No. 200920309806.3 discloses a kind of railway vehicle sound insulating floor, and this floor is certainly Include solid wooden floor board layer, layer of plywood and sheet-metal layers under up to successively, be provided with one layer of sound insulation material in the centre of described layer of plywood Interlayer, this Sound insulation floor structure is simple, and easy for installation, sheet-metal layers and the inner sound isolation material of its underpart have good sound insulation Effect, while sound insulation material produces effective reflection to noise under car, also takes into account damping action, by the vibrations consumption sound of self Wave energy, it is ensured that the integrally-built sound insulation in floor damping effect, it is ensured that internal comfort level.Additionally the use of solid wooden floor board is also Make the internal style of railway car find everything fresh and new, substantially increase the performance that vehicle is luxurious, high-grade, comfortable, attractive in appearance, meet The requirement that passenger is the highest to vehicle environment.Its shortcoming be the bearing capacity of solid wooden floor board and shock resistance poor, along with height The continuous speed-raising of ferrum, it is impossible to bear high load capacity for a long time and can not further be applied.
The Chinese invention patent of Application No. 200810249837.4 discloses a kind of bus deck with sound insulation and decrease of noise functions, institute State floor include following which floor, be followed successively by from top to bottom: flooring laminate layer, damping glue flaggy, doubling plank layer, MULTILAYER COMPOSITE disappear Sound cotton layer, steel plate layer, it is additionally provided with cavity between skinning rubber-plastic sponge layer, doubling plank layer and MULTILAYER COMPOSITE silencing cotton layer, many Layer compound silencing cotton layer include three layers, be followed successively by from top to bottom: mandruka sound absorbing layer, high density rubber-plastic sponge sound insulating layer, from Viscous damping sound insulation layer.The advantage of this invention is to use sealing, sound-absorbing, sound insulation, vibration damping four aspect to realize sound insulation and decrease of noise functions, can The noise being effectively reduced in car, makes the environment in compartment become more comfortable.Its shortcoming is that this multiple structure is complex, no Be readily produced application, additionally in this structure only steel plate layer can load-bearing, leverage impact resistance and the bearing capacity of material, Limit it further to apply.
Such as above-mentioned two patent, in order to improve intensity and the soundproof effect of high ferro bullet train floor material, take multi-layer compound structure, But all there is certain fault of construction, therefore, developing novel high ferro bullet train floor multilayer materials becomes high ferro and enters one The key point that step is widely applied.
