The invention discloses an anti-electromagnetic interference soft-magnetic ferrite material and a preparation method thereof. The anti-electromagnetic interference soft-magnetic ferrite material is characterized by being prepared from the following raw materials in parts by weight: 50-70 parts of iron sesquioxide, 10-20 parts of nickel oxide, 20-30 parts of zinc oxide, 0.1-0.3 part of tungsten oxide, 0.1-0.2 part of boron nitride, 0.1-0.3 part of polyvinylpyrrolidone, 0.4-1 part of saw dust, 0.02-0.06 part of sodium lignin sulfonate, 2-4 parts of organic silicon resin and an appropriate amount of deionized water. According to the anti-electromagnetic interference soft-magnetic ferrite material, the added tungsten oxide is capable of improving the initial permeability of the ferrite material and the added boron nitride is capable of improving the strength of the material; the soft-magnetic ferrite material is simple in production process, excellent in anti-electromagnetic interference property, high in production efficiency, wide in application range and worthy of popularization; besides, the purposes of energy conservation and emission reduction are achieved.
