Bonding ferrite magnetic powder for calendaring molding as well as preparation method and application of bonding ferrite magnetic powder
The invention provides bonded ferrite magnetic powder for calendaring molding as well as a preparation method and application thereof, and relates to the technical field of ferrite materials. Specifically, the preparation method comprises the following steps: fully mixing strontium carbonate, strontium chloride and iron red, and carrying out pelletizing treatment to obtain pellets; dividing the pellets into first pellets and second pellets, and independently sintering and grinding the first pellets and the second pellets to obtain fine pellets with the average particle size of 0.2-0.4 mu m and coarse pellets with the average particle size of 1.6-2.0 mu m; the fine pellets and the coarse pellets are mixed according to the mass ratio of 10%-30%: 1, annealing treatment and surface treatment are sequentially carried out after drying, and bonded ferrite magnetic powder is obtained after drying and crushing are carried out; a reagent for surface treatment comprises an acetylene surfactant. The preparation method is simple and easy to implement, and the magnetic material prepared from the magnetic powder has extremely high residual magnetism and magnet intrinsic coercive force and has wide application prospects.
本发明提供了一种压延成型用粘结铁氧体磁粉及其制备方法和应用，涉及铁氧体材料技术领域。具体而言，所述制备方法包括如下步骤：将碳酸锶、氯化锶和铁红充分混合，经造球处理并得到料球；将料球分为第一料球和第二料球，并将二者独立地进行烧结和研磨处理，得到平均粒径为0.2μm～0.4μm的细粒料球和平均粒径为1.6μm～2.0μm的粗粒料球；将细粒料球和粗粒料球按质量比10％～30％：1进行配比混合，烘干后依次进行退火处理和表面处理，再经干燥、破碎后得到粘结铁氧体磁粉；表面处理的试剂包括乙炔类表面活性剂。本发明的制备方法简单易行，且由磁粉制得磁材料具有极高的剩磁和磁体内禀矫顽力，具有广阔的应用前景。
