The present invention relates to a kind of thermal diffusivity magnetic plastics and preparation method thereof, belong to magnetic plastics technical field.The technical problem to be solved by the present invention is to provide a kind of thermal diffusivity magnetic plastics and preparation method thereof.The nanometer ferrite magnetic-particle of PEG claddings is prepared using coprecipitation for this method, to obtain ferrimagnetism liquid.The ferrimagnetism fine powder directly added in common process is substituted by ferrimagnetism liquid, and externally-applied magnetic field is orientated field when melt mold filling, melt flows are driven by the flowing of magnetic liquid, improve processing flowability, be conducive to promote mold filling rate, and can be injection moulded under more low intensive magnetic fields, reduce energy consumption.By sandwich moulding, obtaining surface has the magnetic material of heat-conducting layer, and preparation method is simple and fast, magnetic material perfect heat-dissipating obtained. |
