Abstract
The utility model relates to a foaming type asphalt damping rubber plate for an automobile, relating to the technical field of automobile material. The foaming type asphalt damping rubber plate for the automobile comprises steel plates and a foaming type asphalt damping layer, wherein the foaming type asphalt damping layer is completely filled between the two layers of steel plates. The foaming type asphalt damping layer has a porous structure and has the thickness of 1.0-5.0mm. The foaming type asphalt damping rubber plate has the effects of shock absorption, noise reduction, sound insulation and heat insulation, and reduces the cost.
Description
Technical field
The utility model belongs to a kind of vehicle material technical field, relates in particular to a kind of automobile with expansion type pitch damping slab rubber.
Background technology
At present, along with the raising of scientific and technological level, the double-decker design appears in automobile, and the oise insulation factor on the benchmark of same steel plate thickness is equivalent to thicken individual layer steel plate oise insulation factor, and obviously it helps improving defening effect, and can save material.Occur collision between the two-layered steel plates in the process of moving for expanding its sound insulation frequency range and preventing, will add acoustic material between two steel plates to obtain better effect.Packing material between existing two-layered steel plates is mainly mineral wool and high molecular foam material, and these material technique for applying complicacies and cost are higher.The application of mineral wool be at automobile through being added on again between two-layered steel plates behind the coating baking, make complex process, workload increases, material cost is higher simultaneously.Being installed in of high molecular foam material is welded; Through electrophoresis baking post-foaming the space of two-layered steel plates is filled; But the more deficiency that all has separately of the kind of high molecular foam material; The rubber pange type because material hardness is less so only play the effect of filling with sound insulation, does not make performance descend and there is cushioning effect after foaming, and the resin type cost that foams is higher.
Summary of the invention
According to above deficiency, the utility model provides a kind of automobile with expansion type pitch damping slab rubber, not only can reach damping, noise reduction, sound insulation, heat insulation effect, and reduce cost.
The technical scheme that the utility model adopts is: automobile is made up of steel plate and expansion type pitch damping layer with expansion type pitch damping slab rubber, is complete filling expansion type pitch damping layer in the middle of two-layered steel plates.
Described pitch damping layer is a kind of loose structure.
Described pitch damping layer thickness is 1.0-5.0mm.
The beneficial effect of the utility model is: not only can reach damping, noise reduction, sound insulation, heat insulation effect, and reduce cost.
Description of drawings
