[0033] A continuous silicon steel long-fiber electrical magnetic material is prepared by the following method:
[0034] S1. Mix organic solvent, manganese hydroxide and deionized water, wherein the molar ratio of organic solvent to manganese oxide is 1:10, add deionized water to finally keep the pH value of the solution at 7.2, and stir to obtain a mixed solvent; The organic solvent described in step S1 is: polyvinyl alcohol.
[0035] S2. Add metal iron salt into the mixed solvent, wherein the mass ratio of the metal iron salt to the mixed solvent is 1:10, and stir evenly to obtain a mixed solution; the metal iron salt in step S2 is: iron nitrate.
[0036] S3. The mixed solution is vacuum dehydrated to a gel state at a temperature of 70° C. to obtain an iron gel;
[0037] S4. When the iron gel temperature is 18°C, add silicon tetrachloride dropwise, and stir until the predetermined ratio of silicon and iron elements is reached to obtain a mixed gel; the molar mass of the sili...
