摘　　要：采用模压设备制备了NdFeB粘结磁体,并研究了粘结助剂(粘结剂和偶联剂)对快淬NdFeB粘结磁体力学性能,包括密度和抗压强度以及磁性能的影响。研究结果表明,添加偶联剂可以提高粘结磁体的性能。使用E-51环氧树脂粘结剂所获得的磁体密度、剩磁、矫顽力、最大磁能积以及抗压强度比用E-44粘结剂的磁体性能要高。随着粘结剂含量的增加,磁体的密度在逐渐降低,磁体的抗压强度在不断变大。而剩磁随着粘结剂含量的增加在不断下降。对矫顽力这个性能来说,1.5%的粘结剂含量为最佳用量。The bonded NdFeB magnets were prepared by die-upsetting process and the effects of binder and coupler on the mechanical and magnetic properties of the magmets were investigated.The results have showed coupling agent may improve the properties of bonded magnets.Higher density and magnetic properties of the magnets have been obtained by using E-51 epoxy resin.
