| titleOfInvention | Manufacturing method of permanent magnet for resin magnet |
| abstract | The present invention relates to a method for producing a permanent magnet for thermosetting resin magnets, and has a composition of Nd 3 + x Fe 78.5-xyzw Co y Hf 1-z Ga z B 18.5-w and a ferromagnetic phase of Nd 2 Fe 14 B Iron (cobalt, hafnium, gallium) -rare earth-boron-based magnetic powders in which Fe 3 B and α-Fe coexist and complex with each other (wherein x, y, z, and w are atomic% as 0 ≦ x ≦ 2, 0 ≤ y ≤ 3, 0 ≤ z ≤ 1, 0 ≤ w ≤ 3).) Is prepared as an amorphous powder by using a rapid cooling technique, and then subjected to a temperature of 550-750 ° C. under a magnetic field of 2-7 kG. After 60 minutes, the powder obtained by pulverization and the ferrite magnetic powder were mixed and surface treated using a 0.5-2.0 wt% silane coupling agent to add 1-30 wt% of 5-30 wt% aliphatic carboxylic acid ester. The thermosetting resin was mixed and molded at a pressure of 1-10 ton / cm 2 under a magnetic field of 2-10 kOe to maintain 1-4 hours at a temperature of 100-200 ° C. |
