Description
Technical field
The present invention relates to vehicle vibration damping noise reduction technology field, particularly relate to a kind of vehicle vibration damping body insulation plate and preparation method thereof.
Background technology
Progress along with the auto trade manufacturing technology, people more and more pay close attention to the control of manned vehicle internal car noise, because domestic automobile manufacturing technology basis is relatively weaker, when automobile research and development design, the very difficult key element design that will affect car load NVH quality puts in place, always carry out again the NVH rectification after out at entire vehicle, it mainly is the use by body insulations such as interior floor, interior trims, obstruct community noise and vibration thereof are delivered to take advantage of drives in the cabin, internal car noise is reduced greatly, therefore very high to the performance requriements of auto sound material.All there is different shortcomings in all auto sound materials at present, the compound type damping steel plate is difficult for fitting fully on the sheet metal component surface of larger radian, the rear existence of installation warps, the convex closure phenomenon, thereby the soundproof effect that impact is whole, and damping steel plate is difficult to according to sheet metal component feature free forming, can only be applied on simple in structure, the comparatively smooth panel beating profile, range of use is more limited.The gas that pitch class damping mat produces in fusion process can not in time discharge and be strapped between damping mat and sheet metal structural, not only affects bonding and soundproof effect, and can produce pernicious gas when high temperature, affects environment inside car, is detrimental to health.The high temperature resistant low-temperature properties of rubber-like damping mat is relatively poor, and oil resistant is easily not aging.The more important thing is that asphalt plank and rubber plate etc. are when linking to each other with materials such as metal or tapetum fibrosums, need to apply adhesive at the binding face of damping mat and sheet metal structural or nylon, tapetum fibrosum makes them bonding, not only consume human resources, increase use cost, and organic adhesion agent exist agingly harden, caducous phenomenon, heavy metal Cr, Pd, Cd content overproof in use can produce poisonous volatile gas, the heavy damage health.
Patent documentation CN102108742A provides a kind of body insulation: between ethylene resin layer and non-woven layer, inject asphalt mixture, and on non-weaving cloth stacking isocyanurate foam.This materials'use polyurethane material, inflammable, when high temperature, can produce pernicious gas, and this body insulation manufacturing is very complicated, consumes a large amount of manpowers, expensive.Patent CN2502896 announces a kind of plastics composite sheet body insulation, is comprised of surface layer, interlayer, basic unit, and surface layer is the PVC plastic sheet, and interlayer is the EVA glued membrane, and basic unit is PE or PP foamed plastic sheet.Because the PVC material soundproofing properties is not good, flame retardance is bad, non-refractory, and the easily distortion of in hotter environment, working, easily aging, intensity is low, and contains halogen in the material, can produce pernicious gas, so the very not environmental protection of this body insulation.Patent CN2612520Y discloses a kind of composite damping board that comprises bottom, top layer, damping layer three-decker, and what used on the bottom of this composite damping board and top layer is wood-based planet, greatly increases auto body weight, affects the performance of vehicle complete vehicle.Damping layer is connected by adhesive agent with bottom, top layer, can produce poisonous gas, is detrimental to health.
In sum, commercial car damping plate on the Vehicles Collected from Market, all in various degree various adhesion agent of use, thereby the poisonous volatile gas that in routine use, all can dissociate, can pollute the space environment in the car case, personnel's health is by bus caused certain injury.
Summary of the invention
The use adhesion agent that exists for vehicle vibration damping damping panel in the prior art and use in can discharge the technical matters of noxious gas, special following technical scheme proposed:
A kind of car damping plate, comprise the composite material by inorganic filler and thermoplastic base resin preparation, consist of with felt rug hot pressing, prepare inorganic filler and described thermoplastic resin organic--inorganic foamed hybrid composite material, then the composite material hot-melt extruded is made composite plate, at last composite plate and felt rug are obtained the MULTILAYER COMPOSITE damping panel through hot pressing.
Described inorganic filler is zinc oxide, calcium carbonate, titanium dioxide, quartz, emery powdor; Or phytoclasts (such as straw wood powder, sawdust etc.), stone flour (such as dolomite rock powder, medical stone powder, dicalcium powder, french talc, dolomite dust, powder of lacquer putty for use on etc.), organic waste materials (such as the fine powder of the engineering plastics such as polysulfones, polyimide).Inorganic filler is preferably dolomite rock powder, and the particle diameter of dolomite rock powder can be nanoscale or micron order or millimetre-sized yardstick.
