The present invention discloses a corrosion-resistant magnetic material and its production process, comprising the following weight parts of raw materials: 60-70 parts of magnetic matrix, 20-30 parts of polyamide, 1-3 parts of polytetrafluoroethylene, 10-12 parts of nanomaterials, and 6-10 parts of modified microcrystalline cellulose; The production process includes the following steps for preparation.
Step 1: Add the magnetic matrix, polyamide, polytetrafluoroethylene, nanomaterials, and modified microcrystalline cellulose into the mixer and mix and stir for 20-40 minutes. After mixing and stirring, transfer the obtained material to a drying oven and dry at 70 ℃ for 4-6 hours to obtain the mixture;
Step 2: Transfer the mixture obtained in the first step to an extruder for extrusion granulation, mix and extrude at 200-240 ℃, and cut into particles with a diameter of 6-12mm. Dry the particles at 60-80 ℃ for 20 hours. Inject the dried particles into shape at 240-260 ℃ with a mold temperature of 70-80 ℃.
