Preparation method of electric wire and cable with soft magnetic wire braided layer

The invention discloses a preparation method of an electric wire and cable with a soft magnetic wire braided layer, which comprises the following steps: firstly, preparing a conductor wire core, and wrapping the periphery of the conductor wire core with a forming protective layer; then mixing and stirring an adhesive, the samarium-iron-nitrogen powder, a processing aid, a high-molecular compatilizer and a dispersion accelerant in parts by mass, and carrying out high-temperature banburying and wire drawing molding to obtain a soft magnetic wire and magnetizing the soft magnetic wire; the soft magnetic wires and the braided fabric are further mixed and braided through a high-speed braiding machine to form a soft magnetic wire braided layer, and the magnetic attraction wire is obtained. The invention provides a formula for preparing the soft magnetic wire with the magnetic force, the soft magnetic wire and the braided fabric are mixed and braided to obtain the soft magnetic wire braided layer with the adsorption
