PROBLEM TO BE SOLVED : To provide a rare earth bond magnet arranged so that the drop of its high-temperature mechanical strength can be suppressed without losing the advantage of a conventional rare earth bond magnet.SOLUTION : A compound for rare earth bond magnet use according to the present invention comprises : a resin composition arranged by blending an epoxy resin (A), a phenol resin hardening agent (B) and a hardening accelerator (C); and powder (D) for rare earth bond magnet use. In addition, a method for manufacturing a rare earth bond magnet according to the present invention comprises : the first step of synthesizing a resin composition by blending an epoxy resin (A), a phenol resin hardening agent (B) and a hardening accelerator (C); the second step of preparing a compound for rare earth bond magnet use by mixing powder (D) for rare earth bond magnet use with the resin composition; the third step of preparing a mold of the compound for rare earth bond magnet use by compression molding of the compound for rare earth bond magnet use; and the fourth step of performing a thermal treatment on the mold. A rare earth bond magnet according to the present invention is arranged by use of a compound for rare earth bond magnet use according to the present invention. The rare earth bond magnet is manufactured by the method for manufacturing a rare earth bond magnet according to the present invention. |
