| titleOfInvention | Manufacture of compound magnet |
| abstract | PURPOSE:To enhance the magnetic properties and corrosion resistance by a method wherein, in the manufacturing process of a compound magnet to pressure-mold a mixture of rare earth magnetic powder and a binder, the rare earth magnetic powder is surface-processed with a fluorine coupling agent. CONSTITUTION:The rare earth magnetic power contains alloy powder represented by a general formula R2T14B (where R represents rare earth group element including yttrium, likewise T: transition metal and B: boron). The fluorine base coupling agent is oligomer structure as represented by the formula I where n=1-3, iPrO: isopropyl radical, Mi: -CF2-(OCF-CF2)x-(OCF2)y-OCF3, x=1-10, y=1-10. The pressure molding falls under injection molding or compression molding. The surface of magnetic powder may be modified by either one out of the following tow processes i.e., the coupling agent itself or the same melted into a small amount of solvent is dripped or sprayed while agitating the magnetic powder or the coupling agent melted into a large amount of the solvent is mixed with the magnetic powder to be agitated and then the solvent is dried up to be removed. |
