| titleOfInvention | Manufacturing method of thermosetting compound powder for rare earth plastic magnet |
| abstract | The present invention relates to a method for producing a thermosetting drum polymer powder for rare earth-based plastic magnets, and to provide a thermosetting composite powder for rare earth-based plastic magnets that provides optimum magnetic properties and has excellent compression moldability. have.n n n In the present invention, Nd (a) Fe (b) Co (c) Zr (d) B (e) (where a = 9-12 atomic%, b = 70-82 atomic%, c = 1-10 atomic%, After melting the magnetic alloy of d = 0.5 to 3.0 atomic%, e = 3 to 10 atomic%, a + b + c + d + e = 100 atomic%), the amorphous magnetic powder was prepared by the eviction melt rotary rapid cooling method. One step, heat-treating the magnetic powder at 600 ~ YY800 ℃ for 0.5-2 hours, adjusting the magnetic powder is heat-treated as described above to have a particle size of 60 ~ 200 mesh and the axial ratio of 1.0 ~ 3.0.n n n Surface treatment of the magnetic powder having a particle size and axial ratio adjusted as described above using a silane coupling agent of 0.5 to 2.0% by weight, 5-30% by weight of aliphatic carboxylic acid ester of the surface-treated magnetic powder as described above It is a method of manufacturing a thermosetting composite magnetic powder for rare earth-based plastic magnets, including the step of mixing with the added 1 to 5% by weight of the thermosetting resin.n n n The present invention is suitable for the plastic magnet, the composition, shape, particle size ?? By providing the compound magnetic powder, the molding properties of the magnetic powder as well as the magnetic properties of the rare earth-based plastic magnets are greatly improved. |
