| titleOfInvention | Preparation method of high-impedance iron-silicon material and integrated inductor containing iron-silicon material |
| abstract | The invention discloses a preparation method of a high-impedance iron-silicon material and an integrated inductor containing the iron-silicon material, and the preparation method of the high-impedance iron-silicon material comprises the following steps: selecting 400-plus-500-mesh water atomized iron-silicon powder for ball milling; adding the ball-milled powder into a coating liquid for insulating coating, wherein the coating liquid is prepared by dissolving two or more of phosphoric acid, aluminum dihydrogen phosphate, chromic acid and potash water glass in acetone; adding the powder subjected to insulation coating into secondary coating liquid for secondary coating, wherein the secondary coating liquid is prepared by dissolving one or more of silicone resin and liquid glue in acetone; sequentially granulating, airing and baking the secondarily coated powder; cooling to room temperature, adding auxiliary materials, stirring, and sieving. An integrated inductor is prepared by pressing, molding and baking the high-impedance iron silicon material and a coil. The invention effectively improves the particle morphology of the powder, greatly improves the insulativity among the powder and reduces the loss of the magnetic core. |
