The invention discloses a high-frequency high-power soft-magnetic ferrite material and its preparation method. The invention is characterized in that the high-frequency high-power soft-magnetic ferrite material is prepared from the following raw materials, by weight, 50-70 parts of ferric oxide, 28-32 parts of manganese oxide, 14-18 parts of zinc oxide, 0.3-0.5 part of titanium dioxide, 0.2-0.4 part of calcium carbonate, 0.1-0.3 part of polyvinylpyrrolidone, 0.4-1 part of sawdust, 0.02-0.06 part of sodium lignosulfonate, 2-4 parts of organic silicone resin and a proper amount of deionized water. The soft-magnetic ferrite material has high frequency and high power, can meet requirements of a power source material on high saturation magnetic induction, low loss and stability, has advantages of low production cost, simple operation and good wear resistance, and is beneficial to miniaturization and high-efficiency development of the power source material.
