Soft magnetic alloy material and preparation method of soft magnetic alloy material

The invention discloses a soft magnetic alloy material and a preparation method thereof. The preparation method comprises the steps of providing and smelting a first alloy material, a second alloy material and a carbonyl iron material into first metal liquid, second metal liquid and third metal liquid correspondingly and cooling correspondingly; treating cooled first alloy powder, cooled second alloy powder and cooled carbonyl iron powder for 1-2 hours in the protective atmosphere of 350 DEG C, 450-600 DEG C and 300 DEG C respectively, and obtaining first alloy powder, second alloy powder and carbonyl iron powder; mixing the first alloy powder, the second alloy powder and carbonyl iron powder according to a preset proportion, and then mixing with o-cresol formaldehyde epoxy resin, methyl nadic anhydride, benzyl triphenyl phosphorus bromide, 2-methylimidazole, antimony trioxide, silica powder, methacryloyloxy propyl trimethoxy silane and a release agent to obtain a mixed material, melting and mixing the mixed
