的強度も低下し。[Prior Art and Problems to be Solved by the Invention] It is well known to mix and knead magnetic powder and a binder and manufacture a composite magnet by extrusion molding, compression molding, or injection molding. However, the drawback is that the magnetic properties are reduced by the volume of the non-magnetic binder and additives. In order to improve this drawback, it is necessary to increase the amount of magnetic powder packed and to minimize the degree of orientation of the magnetic powder. However, in general, if the amount of magnetic powder mixed in is increased, the melt viscosity of the kneaded product will be high, the flow will be poor during molding, the moldability will be poor, or the product will not be obtained. Moreover, even if the shape is barely formed, the degree of orientation of the magnetic powder decreases, and satisfactory magnetic properties cannot be obtained, and mechanical strength also decreases.
複合磁石の利点が失われてしまう。The advantages of composite magnets are lost.

This method has the effect of changing the surface of the magnetic powder from hydrophilic to lipophilic, improving its compatibility with the binder, and therefore improving the filling rate and orientation.

Composite magnets are expected to be applied to small motors, office automation equipment, etc., and there is an increasing demand for composite magnets with thinner walls.
磁気特性をそこなわずに機械的強度を向上させる事が重
要な課題となっている。Improving mechanical strength without impairing magnetic properties is an important issue.

せるに至った。As a result of intensive research to find a manufacturing method for composite magnets that is also highly economical, we discovered that the magnetic powder used was surface treated in the presence of both a silane coupling agent and a titanium coupling agent before being mixed and kneaded with a binder. The present inventors discovered that the above object can be achieved by carrying out the following steps, and have completed the present invention.
