Abstract
A device and method for preparing a thermosetting bonded magnet are provided, the device includes a compressed air glue feeding tank and a composite-function mold. A feeding end of the compressed air glue feeding tank is connected to the composite-function mold. The composite-function mold includes a housing, the housing is disposed at an upper end and a lower end of the composite-function mold, and the housing includes a polytetrafluoroethylene upper cover and a polytetrafluoroethylene lower cover; the polytetrafluoroethylene upper cover and the polytetrafluoroethylene lower cover are respectively disposed at the upper end and the lower end of composite-function mold. The method uses a silica gel material as a binder for anisotropic magnets, and the selected raw materials and process are suitable for quickly obtaining a uniform magnet slurry. The curing process is controllable, and there is no organic solvent or heating during the mixing process.
