| titleOfInvention | Manufacturing method of thermoplastic compound powder for rare earth plastic magnet |
| abstract | The present invention relates to a method for producing a thermoplastic composite powder for rare earth-based plastic magnets, and to provide a thermoplastic composite powder for rare earth-based plastic magnets that provides optimum magnetic properties and is excellent in injection molding. .n n n In the present invention, Nd (a) Fe (b) Co (c) B (d), wherein a = 13-16 atomic%, b = 70-82 atomic%, c = 1-10 atomic%, d = 3- 10 atomic%, a + b + c + d = 100 atomic%) to melt the magnetic alloy to prepare an amorphous magnetic powder by the extraction melt rotary rapid cooling method, the magnetic powder is 0.5- at 600-800 ℃ Heat-treating for 2 hours, adjusting the heat-treated magnetic powder to have an axial ratio of 100-400 mesh and 1.0-2.5.n n n Surface-treated magnetic powder having a particle size and axial ratio controlled as described above using a silane coupling agent of 0.5-2.0% by weight, and mixing the surface-treated magnetic powder with 5-15% by weight of thermoplastic resin as described above. It comprises a method for producing a thermoplastic compound powder for rare earth-based plastic magnets.n n n The present invention is a suitable composition, granular particle size for plastic magnets? Providing a composite magnetic component has a great effect in improving the magnetic properties of the rare earth plastic magnet as well as the injection molding characteristics of the magnetic powder. |
