Abstract
The present invention relates to one kind of cavity vibration-isolating cushion for vehicle body. The cavity vibration-isolating cushion includes skeleton material and expanding body material. The skeleton material is nylon PA6.6. The expanding body material consists of crosslinked polyethylene 5-18 weight portions, basic plastic copolymer 15-85 weight portions, the first foaming agent 1-15 weight portions, the second foaming agent 1.5-8 weight portions and crosslinking agent 0.5-2.7 weight portions. The product of the present invention may be used in blocking cavity passages in vehicle body so as to isolate vibration and noise and improve the environment inside the vehicle effectively.
Description
Technical field
The present invention relates to auto parts machinery, relate in particular to a kind of car body cavity vibration isolating pad.
Background technology
Along with developing of automobile industry, people are more and more higher to the requirement of " security, comfortableness, the feature of environmental protection " of car, and the standard-required to " sound insulation, vibration isolation, anticorrosion, noise control " in car is sat the cabin also constantly promotes.The AE personnel have done the technology upgrading of sound insulation vibration isolation to enclosure sound heat insulating mattress, car internal sound insulation, vibration isolation carpet, vehicle body sticking glass, car roof or the like before ride-control, the front and back in car at present, and vibration and noise that car is sat in the cabin have obtained improving effectively.But the cavity passage in the body structure also can vibrative noise, and this technical problem is not well solved all the time.
Vehicle body in manufacturing processed be earlier by metal metal plate material by the die stamping moulding after, belong to seam by plates of automobile such as inner panel, stiffening plate and outside plates and form.Therefore the columnar structure spare that the vertical Beam of necessary gap and space, particularly reinforcement A, B, C, D post and two bottom sides has formed hollow generally is bound to form in the middle of inner panel and stiffening plate and outside plate.The hollow structure of these column pieces and vertical Beam has guaranteed the intensity and the rigidity of body structure effectively.Therefore the cavity state in the body structure is must have, but just because of the hollow cavity of body structure has also formed the specific channel that transmits ambient noise and vibration, vehicle body is at ceiling simultaneously, the metal metal plate spare of the vertical isometric form of Beam also can be because of the distortion of structure when crossing the road ditch, vibration forms sound, again can be in the high vehicle speeds motion because of extraneous blast, windage to vehicle body form sympathetic response sound and pavement of road sandstone also can be at the volley to the vehicle body sound that impacts, have resonant frequency can form the vibration and the sound to vehicle-body outer panel again in the time of in the motion, these noises and vibration all can be in vehicle bodies, cavity between the outside plate reaches the channelling effect of quick transmission.
Be the further vibration damping sound insulation technology that promotes, enter the research work to the cavity passage in the body structure 20 end of the centurys again, studies show that, as long as reasonably seal the vehicle body cavity passage, just can improve vibration and noise in the car seat cabin effectively.
Summary of the invention
Purpose of the present invention is exactly in order to solve the problem that above-mentioned prior art exists, thereby provides a kind of bodywork cavity that can seal can improve car effectively and sit the vibration in the cabin and the car body cavity vibration isolating pad of noise.
In order to achieve the above object, the present invention adopts following technical scheme:
Car body cavity vibration isolating pad comprises basic skeleton material and expander material, it is characterized in that, described basic skeleton material is nylon PA6.6, and described expander material comprises the raw material of following component and weight part content:
Crosslinked polyethylene 5～18,
Base plastic copolymer 1 5～85,
First whipping agent 1～15,
Second whipping agent 1.5～8,
Linking agent 0.5～2.7;
Described base plastic multipolymer is one or more the mixture in ethylene-methyl acrylate copolymer, ethylene-butyl acrylate copolymer, the ethylene-vinyl acetate copolymer;
Described first whipping agent is Cellmic C 121 or whipping agent ADCA;
Described second whipping agent is right-(right-the sulfonyl hydrazide phenyl ether) or whipping agent OBSH.
The weight ratio of described basic skeleton material and expander material is 70～30: 30～70.
Described linking agent is a dicumyl peroxide.
Described expander material also comprises the raw material of following one or more components and weight part content: one package stabilizer 0.5～2, lubricant 1.5～3, oxidation inhibitor 0.1～0.88, mineral dye 0.2～0.8, mineral filler 5～10.
Described one package stabilizer is a solid calcium zinc, and described lubricant is a Zinc Stearate, and described oxidation inhibitor is antioxygen 1010, and described mineral dye is a chromoxide green, and described mineral filler is lime carbonate, kaolin.
In in conjunction with the automobile making technical process, rationally reach the ideal operational procedure, a plurality of car body cavity vibration isolating pads of the present invention are arranged among the appropriate location that bodywork cavity must intercept, by the time body in white through pickling, neutralization, purifying, phosphatization, enters in the stoving of the paint stove behind first road paint again and toasts.In stove behind 170～190 ℃ of high temperature and certain hour, the car body cavity vibration isolating pad part is finished the foaming bonding, part and the inside and outside plate of body in white closely are bonded to one, effectively the cavity passage in the relevant position in the former vehicle body is intercepted, reach totally-enclosed, thereby vibration source and the noise originally locating to import into through bodywork cavity through floor Beam, rear wheel cover, ceiling, preceding coaming plate, door-plate etc. are intercepted, reach and further improve the purpose that car is sat vibration isolation in the cabin, sound insulation, vibration damping, noise reduction.Simultaneously, after car body cavity vibration isolating pad foamed in bodywork cavity and bonds, the intensity of further having reinforced vehicle body all played optimization function to body structure and vehicle body anti-collision, has also obtained important lifting in car comfortableness and security.
