Summary:The invention relates to the technical field of magnetic cores, in particular to a preparation method of a magnetic core surface protective film. Comprising the following steps: S1, carrying out preliminary treatment on a strip to obtain a target magnetic core; s2, putting the solid resin into a reactor, and sublimating the solid resin into gaseous resin under vacuum; s3, conveying the gaseous resin into a heating device, and cracking the gaseous resin to obtain cracked resin; and S4, the cracked resin is conveyed to cooling equipment and cooled to the normal temperature, free resin is obtained, and a layer of compact protective film is formed on the surface of the magnetic core through deposition and polymerization. By vapor deposition of the compact pinhole-free protective film on the target magnetic core, the method has the beneficial effects of low stress and corrosion resistance, is extremely low in water and gas transmittance, and can resist water, salt mist, acid and alkali and oxidation. 本发明涉及磁芯技术领域，具
