減少にも効果を及ぼすこととなる。(Function) When the surface treatment of the magnetic powder, which is a feature of the present invention, is performed, when the resin 2, for example, nylon, and the magnetic powder are in a molten state, the frictional resistance between the surface of the magnetic powder and the nylon material Since the melt viscosity of the composite as a whole is also lowered, there is no need to use a large amount of magnetic powder, and the degree of orientation of the magnetic powder in a magnetic field is also significantly improved. Furthermore, by adding a lubricant such as higher fatty acid salt wax, the moldability and degree of orientation are further improved due to the synergistic effect with the 92 surface treatment agent, and the mold releasability during molding is also improved, which in turn reduces mold wear. This will also have an effect on the reduction.

従来のプラスチック磁石では磁性粉末を結合材料として
のプラスチックに多量に混合、混練すると得られる複合
体の溶融粘度が著しく上昇して成形が困難となるため、
磁性粉末の充填率は85チ(重量)程度に制約される。In conventional plastic magnets, when a large amount of magnetic powder is mixed and kneaded with plastic as a binding material, the melt viscosity of the resulting composite increases significantly, making it difficult to mold.
The filling rate of the magnetic powder is limited to about 85 inches (weight).
又溶融粘度の上昇は磁性粉末の配向を阻害するため磁気
特性は焼結磁石に比較して劣るものにならざるを得なか
った。Furthermore, since the increase in melt viscosity inhibits the orientation of magnetic powder, the magnetic properties are inevitably inferior to those of sintered magnets.
