High-performance injection-molded post-sintered permanent magnetic ferrite magnet and preparation method thereof
The invention relates to the technical field of permanent magnet production. The invention aims to solve the problem that the existing permanent magnetic ferrite is difficult to give consideration tohigh magnetic performance, low cost, multi-pole orientation and complex forming shape and structure. The invention provides a high-performance injection-molded post-sintered permanent magnetic ferritemagnet and a preparation method thereof. The permanent magnetic ferrite magnet is prepared from, by weight, 87-95% of permanent magnetic ferrite magnetic powder, 0.1-1.0% of a surface modifier, 0.3-1.2% of a coupling agent, 4-12% of a composite binder and 0.1-1.0% of a flow aid. The permanent magnetic ferrite magnet is obviously higher than an existing injection-molded permanent magnetic ferritemagnet, can keep the advantages that the existing injection molding permanent magnetic ferrite magnet is prone to forming complex parts in shape and structure and prone to multi-pole orientation, andthe application range of the injection-molded permanent magnetic ferrite magnet can be greatly widened; and the high-performance injection-molded post-sintered permanent magnetic ferrite magnet is widely applied to the fields of electronic water pump rotors, automobile motor rotors, high-end household appliance motor rotors, induction magnetic rings and the like.
本发明涉及永磁磁体生产技术领域，为解决现有永磁铁氧体难以兼顾高磁性能、低成本、多极取向、成型形状结构复杂件的问题，提供了一种高性能注射成型后烧结的永磁铁氧体磁体及其制备方法，所述永磁铁氧体磁体由以下重量百分含量的组分制成：永磁铁氧体磁粉87～95％，表面修饰剂0.1～1.0％，偶联剂0.3～1.2％，复合粘结剂4～12％，流动助剂0.1～1.0％。本发明的永磁铁氧体磁体明显高于现有的注塑永磁铁氧体磁体，同时能够保持现有的注塑永磁铁氧体磁体易成型形状结构复杂件及易多极取向的优点，可以极大地扩宽注塑永磁铁氧体磁体的应用范围；广泛应用于电子水泵转子、汽车电机转子、高端家电电机转子、感应磁环等领域。
