摘要
研究了二茂金属高分子铁磁粉（ＯＰＭ）与快淬钕铁硼磁粉复合制成的一种新的粘结永磁复合材料的性能，并与非磁性高分子粘结钕铁硼的性能进行了比较。结果表明，磁性高分子的含量降低，磁性高分子粘结钕铁硼永磁材料的最大磁能积（ＢＨ）ｍ、剩磁Ｂｒ、矫顽力Ｈｂｃ升高，内禀矫力Ｈｊｃ略为下降；但在含相同体积分数磁粉情况下，磁性高分子粘结ＮｄＦｅＢ的磁性能比非磁性的高分子粘结ＮｄＦｅＢ的磁性能高，其温度稳定性也几乎相同。
The properties of a new magnetic composite which consists of rapid quenching NdFeB magnetic powder and magnetic polymer (OPM) were studied and contrasted with the one of the bonded NdFeB permanent magnet by nonmagnetic polymer, such as epoxy resin. The results show that when the percentage of NdFeB magnetic powder of the magnetic composite increases, the residual flux density Br, the maximum energy product (BH)m and the coercive force Hbc increase, but the intrinsic coercive force Hjc decreases a little. However, when the rapid quenching NdFeB powder in the OPM bonded NdFeB magnet is as much as the one in epoxy resin bonded NeFeB magnet, the magnetic properties Br, (BH)m and Hbc of the former are higher than those of the latter, and the stability of temperature of the former is the same as the latter.
