1. a kind of preparation method being fully oriented soft-magnetic composite material is it is characterised in that it concretely comprises the following steps:

  • 1) material preparesThe flattening metal magnetic that average thickness is 0.5 ~ 5 μ

    m is selected to be raw material;

    Described metal magnetic is iron powder, ferrum silica flour, ferrum aluminum silicon powder, ferrum nikel powder or ferrum nickel molybdenum powder;

    2) mix, casting100 parts of epoxy resin are thoroughly mixed with 20~

    500 parts of flattening metal magnetics, add 1~

    15 part of firming agentDiethylenetriamine, continues stirring 30s, in injection ring mould;

    3) it is fully oriented solidification in magnetic fieldMould after casting is positioned over rapidly in the magnetic field of horizontal direction and is orientated, and by aligned difference, can be divided into three kinds;

    (1), magnet ring horizontal positioned, does not have magnetic field orientating;

    (2), magnet ring horizontal positioned, normal perpendicular to magnetic direction, simultaneously with normalRotated for axle;

    (3), magnet ring is disposed vertically, and normal parallel, in magnetic direction, is rotated with a diameter of axle simultaneously;

    SampleMagnetic field is taken out after orientation solidification.
