Hot-pressing inductance material, preparation method and integrally-formed inductor

The invention discloses a hot-pressing inductance material, a preparation method and an integrally-formed inductor. The preparation method of the hot-pressing inductance material comprises the steps that S1, raw materials are smelted into molten metal at the high temperature, cooling water containing magnesium oxide is adopted for cooling the atomized molten metal, and a powdery composite material is formed; s2, treating the powdery composite material in a reducing atmosphere to obtain a dry composite material; s3, mixing the dried composite material with an aqueous solution containing phosphate, and then drying to form a phosphate-coated composite material; and S4, uniformly mixing the phosphate coated composite material with a liquid resin material to obtain the hot-pressing inductance material. Through the non-crystallization design of material components, the material has high insulation resistance, the loss is further reduced through multi-layer coating, the hot pressing temperature is designed at a nano
