Abstract: Disclosed is a novel high-density magnetic composite material for an inductor. The material is composed of 6-12% of high-temperature resin glue and 88-94% of magnetic powder body in percentage by weight. An integrated inductor magnetic core is simply prepared by means of the magnetic composite material of the disclosure without a large press, thus saving the device investment. The mold loss in a pressing process is reduced, and the production cost is reduced. The operation is simple, a magnet of a complex shape can be produced, and an oversized magnet can be produced. A closed magnetic circuit is formed, and the EMI effect is good. The magnetic composite material of the disclosure enables the density of a solidified magnet to be high under the action of special high-temperature resin glue, it can be guaranteed that the density is 5.5-6.2 g/cm3, the sensitive quality value for preparing an inductor is high, and the initial permeability can be 14? or above.
