Abstract：

With　the　development　of　bonded　Nd-Fe-B　magnets,　modifying　epoxy　resin　(EP)　binder　has　become　a　key　factor　to　improve　the　properties　of　bonded　Nd-Fe-B　magnets.　In　this　work,　the　magnetic　properties,　compressive　strength,　and　microstructure　of　the　bonded　Nd-Fe-B　magnets　with　diaminodiphenylmethane　(DDM)-cured　EP　binder　were　systematically　investigated.　The　results　show　that　adding　20　wt%　DDM　to　EP　monomer　maintains　excellent　magnetic　properties　while　obtaining　optimal　temperature　resistance　and　high　compressive　strength　for　magnets.　Because　the　molecular　structure　of　the　DDM　curing　agent　contains　rigid　groups,　it　can　enhance　the　heat　resistance　and　mechanical　properties　of　the　EP　binder.　In　addition,　fracture　surface　morphology　observation　reveals　the　bonding　mechanism　of　DDM-EP　bonded　magnets　and　confirms　the　advantageous　nature　of　DDM-EP　binder　for　bonded　magnets.　©　1965-2012　IEEE.
