Metal matrix composite wire, power inductor, and preparation methods for same

A preparation method for a metal matrix composite wire includes the following steps: 1) preparing a metal inner core; 2) preparing a glass-resin mixture; 3) dissolving self-adhesive resin in a solvent to prepare a self-adhesive resin solution; 4) uniformly coating the glass-resin mixture on a surface of the metal inner core, then coating the self-adhesive resin solution on a surface of the glass-resin mixture, and performing drying at a temperature of 80 C. to 150 C.; and 5) repeating the step 4) until a thickness of the glass-resin mixture plus the self-adhesive resin reaches 2 to 10 m. When an inductor is prepared by using the composite wire, the inductor may have relatively good weather resistance, a relatively good dielectric voltage-withstand capability, as well as relatively good high-temperature resistance and electrical performance.
