摘　　要：用改性环氧树脂作粘结剂,在不同工艺条件下制备粘结NdFeB磁体,并对其性能进行了研究.结果表明,改性环氧树脂粘结NdFeB磁体性能高于传统环氧树脂粘结NdFeB磁体,在模压温度130℃、保压时间2 min、固化时间120 min、固化温度120℃条件下制备的磁体,其磁性能最佳.An investigation was carried out on the bonded NdFeB magnets made by using modified epoxy resin as adhesive under different process conditions.The results show that the magnetic properties of the bonded NdFeB is better than that of the NdFeB made using traditional expoxy resin.The magnetic properties go up to the peak when the molding temperature is 130℃,dwell time 2 min,curing temperature 120℃ and curing time 120min.
