技术范围: 本发明叙述用于磁性涂层的磁性粒子分散体系的制备方法。本分散体系中的磁性粒子粒度小而且在整个涂层内分布均匀。背景: 在磁记录材料的制备中(例如磁盘),一般是将磁性粒子(例如γ-Fe_2O_3)分散在粘合剂混合物中形成磁记录材料。磁浆通常是把配方中各组分在一起球磨一定时间制成。制备磁浆时力求将磁 Technical Field: The present invention describes a method for preparing a magnetic particle dispersion for a magnetic coating. The magnetic particles in this dispersion have small particle size and are uniformly distributed throughout the coating. BACKGROUND In the manufacture of magnetic recording materials, such as magnetic disks, it is common to disperse magnetic particles, such as γ-Fe_2O_3, in a binder mixture to form a magnetic recording material. Magnetic slurry is usually the ingredients in the recipe together for some time ball milling. When preparing magnetic slurry magnetic will be sought
