| titleOfInvention | Alnico compound magnetic powder production method for thermoplastic resin magnet |
| abstract | The present invention relates to a method for producing alnico composite magnetic powder for thermosetting resin magnets, and more particularly, to a method for preparing alnico composite magnetic powder for thermosetting resin magnets using a rapid cooling method.n n n According to the present invention, an Alnico alloy having Al-Ni-Co-Cu-Fe or Al-Ni-Co-Cu-Ti-Fe as a main component is quenched to form a powder and then pulverized into fine powder and 650- After heat treatment for 2-30 minutes in the magnetic field while loading 1-10KOe external magnetic field at 950 o C temperature, aging heat treatment for 1-10 hours at 500-700 o C based on the weight of the magnetic powder Surface treatment with 0.5-2.0 wt% silane coupling agent and mixing 5-15 wt% thermoplastic resin based on the weight of the surface-treated magnetic powder Provided is a magnetic powder production method, which can be prepared in the alnico-based composite powder for a thermoplastic resin magnet in a simple process is cheap, easy to grind, inexpensive compared to the conventional manufacturing method. |
