High-strength novel granulation powder for integrated inductor and preparation method of granulation powder
The invention discloses high-strength novel granulation powder for an integrated inductor and a preparation method of the granulation powder, phenolic epoxy resin with multiple epoxy groups and phenolic resin with multiple curing sites are used as main components of an organic adhesive, and a layer of organic adhesive can be coated outside magnetic powder to form a structure similar to a'core-shell '. And the bonding stability and strength of the magnetic powder are improved. The magnetic powder treated by the process can form a more compact three-dimensional cross-linked network mainly comprising covalent bonds among the magnetic powder, the organic adhesive and the magnetic powder during hot pressing, and meanwhile, the cross-linking mode can also enhance Van der Waals force among adhesive molecules and weak bond interaction of hydrogen bonds and the like; therefore, the bonding strength among the magnetic powder, the organic adhesive and the magnetic powder can be improved.
本发明公开一种高强度的新型一体电感用造粒粉及其制备方法，使用多环氧基的酚醛环氧型树脂和多固化位点的酚醛型树脂作为有机黏结剂的主要构成组分，可在磁粉外部包覆一层有机黏结剂，形成类似于“核‑壳”结构，增加磁粉间结合的稳定和强度。用此工艺处理的磁粉在热压时可以在磁粉—有机黏结剂—磁粉间形成以共价键为主且更为密实的三维交联网络，同时此交联方式亦可加强黏结剂分子间范德华力和氢键等弱键相互作用，即可提升磁粉—有机黏结剂—磁粉间的结合强度。
