发明内容
基于背景技术存在的技术问题，本发明提出了一种高抗折强度镍锌软磁铁氧体材料，保证高频性能的同时，抗折强度性能极好，性能稳定。
本发明提出的一种高抗折强度镍锌软磁铁氧体材料，其原料包括主料与辅料，主料与辅料的重量份比为100：0.06-0.12；主料按摩尔份包括：氧化铁30-60份，氧化锌30-50份，氧化镍2-6份，氧化亚镍15-25份，氧化铜4-10份；辅料按重量份包括：五氧化二钒20-30份，三氧化二铋25-45份，氧化镧8-12份，五氧化二钽14-20份，二氧化铅3-9份，三氧化钼12-20份，氧化镁8-16份，碳化铌14-22份，二氧化硅20-35份。
优选地，主料与辅料的重量份比为100：0.08-0.1。
优选地，氧化铁、氧化锌、氧化镍、氧化亚镍、氧化铜的重量比为40-50：35-45：3-5：18-22：6-8。
优选地，五氧化二钒、三氧化二铋、五氧化二钽、二氧化铅、氧化镁的重量比为22-28：30-40：16-18：5-7：10-14。
优选地，还包括改性炭球，改性炭球与主料的重量比为100：3-5。
优选地，改性炭球采用如下工艺制备：将氯化钯、羧甲基纤维素、水混合均匀，加入氢氧化钠溶液调节体系pH值至6-6.7，水浴保温，冷却至室温，加入羧甲基纤维素混合搅拌均匀，送入密闭反应釜中进行水热炭化，冷却洗涤，干燥，送入管式炉中氮气保护下升温，二氧化碳活化，氮气保护下冷却至室温得到改性炭球。
优选地，改性炭球采用如下工艺制备：将氯化钯、羧甲基纤维素、水混合均匀，加入氢氧化钠溶液调节体系pH值至6-6.7，水浴保温，冷却至室温，加入羧甲基纤维素混合搅拌均匀，送入密闭反应釜中，在温度220-240℃水热炭化4-10h，冷却洗涤，130-150℃干燥60-120min，送入管式炉中氮气保护下从室温升温至850-950℃，二氧化碳活化25-45min，氮气保护下冷却至室温得到改性炭球。
优选地，改性炭球采用如下工艺制备：按重量份将15-25份氯化钯、2-4份羧甲基纤维素、50-90份水混合均匀，加入浓度为0.15-0.2mol/L的氢氧化钠溶液调节体系pH值至6-6.7，水浴保温15-30min，水浴温度为75-85℃，冷却至室温，加入15-25份羧甲基纤维素混合搅拌均匀，送入密闭反应釜中，在温度220-240℃水热炭化4-10h，冷却洗涤，130-150℃干燥60-120min，送入管式炉中氮气保护下从室温升温至850-950℃，二氧化碳活化25-45min，氮气保护下冷却至室温得到改性炭球。
本发明采用常规制备工艺制得。
本发明的改性炭球中，氯化钯经过羧甲基纤维素钠处理，在水浴反应下，所得产物粒径分布窄，粒径小，形状均一，团聚程度低，分散性好，稳定性高，进一步与羧甲基纤维素作用，相互间分散均匀，经过一定工艺处理后，所得产物球形度极高，比表面积大，同时由于羧甲基纤维素的表面富含含氧官能团，与之接枝后经过一系列作用，并采用二氧化碳活化炭球前驱体，不仅不损坏炭球前驱体球形形貌，而且比表面积大，内部空隙结构好。
本发明在传统镍锌软磁铁氧体的基础上通过配方的调整，通过调整主要原材料NiO、ZnO、Fe2O3、CuO的配合，并添加改性炭球就行可有效促使上述组分间相互分散均匀，由于改性炭球比较面积大，可对周围物料进行有效吸附，综合作用，使本发明不仅保证高频性能的同时，而且综合性能稳定，在满足其电性能的前提下，抗折强度极好，特别适用于目前电子产品小薄化后对产品抗折强度提出的要求，保证产品具有更好的耐摔打、抗碰撞、防震、抗机械破坏能力，达到保证产品性能的稳定和使用寿命的延长，符合电子设备小型化发展方向，其市场前景广阔。
