| titleOfInvention | Soft magnetic powder core and preparation method thereof |
| abstract | The invention relates to a soft magnetic powder core and a preparation method thereof. The soft magnetic powder core is prepared from the following raw materials in parts by mass: 100 parts of iron-based metal soft magnetic powder; 0.01 to 0.3 portion of coupling agent; 3-6 parts of a forming agent; the forming agent comprises the following components in parts by weight: 2-4 parts of first resin; 1-2 parts of phenolic resin; 0.03 to 0.3 portion of curing accelerator; the first resin is at least one selected from functional epoxy resin, cyanate ester and bismaleimide resin. In the raw materials of the soft magnetic powder core, the coupling agent is used for coupling treatment of the surface of the iron-based metal soft magnetic powder, the forming agent can be uniformly and firmly adsorbed on the surface of the iron-based metal soft magnetic powder after coupling treatment, and the forming agent also plays a role in mechanical transmission in the preparation process of the soft magnetic powder core. The whole soft magnetic powder core can be molded under lower molding pressure, so that the process difficulty that the traditional soft magnetic powder core needs high-pressure molding is solved, and the production efficiency is favorably improved. |
