The invention relates to a preparation method of ferroferric oxide magnetic nano particle emulsion in the technical field of nano materials. The magnetic nano particle water dispersing liquid is obtained by adding a magnetic nano particle into water through ultrasonic dispersion processing; and an oil phase is added into the magnetic nano particle water dispersing liquid to carry out homogenization processing to obtain the ferroferric oxide magnetic nano particle emulsion. The prepared emulsion has the liquid drop size of 30-50 microns, low poison, environmental protection, favorable long-term stability and magnetic functionalized characteristic without using a surface active agent, and can be used for preparing a novel functional material or applied to a functional use requirement occasion.
