The invention discloses a neodymium-iron-boron permanent magnet material. The neodymium-iron-boron permanent magnet material is prepared by the following steps of preparing a rare earth permanent magnet ingot; smashing the rare earth permanent magnet ingot into rare earth magnetic powder; performing surface plasma treatment on the rare earth magnetic powder and Zn-Al alloy powder; preparing fluorinated graphene; mixing the rare earth magnetic powder, the Zn-Al alloy powder, the fluorinated graphene and auxiliaries, shaping under a magnetic field and sintering to obtain a primary product; and forming a corrosion resistant layer on the surface of the primary product. The neodymium-iron-boron permanent magnet material prepared by the invention has relatively high residual magnetism, coercivity, working temperature, corrosion resistance and flexibility.
