Description

Composite magnetic powder Technical Field The utility model relates to composite magnetic powder, in particular to composite magnetic powder for manufacturing an inductance magnetic core. Background An inductor (Inductor) is a passive electronic component that is widely used in a variety of electronic circuits. Therefore, with miniaturization of electronic products, the smaller the size of the inductor is, the better. Inductors typically include a core and leads, and to reduce the size of the inductor, iron powder is used to form a higher density core. However, when a magnetic core is made of iron powder, the manufactured magnetic core has a problem of corrosion resistance because the iron has a property of being easily rusted. In the prior art, anti-corrosion materials are sprayed on the surface after the inductor is formed, but the step of spraying the anti-corrosion materials not only increases the process steps and the cost, but also has the environmental protection problem of treating solvents. Therefore, how to overcome the above-mentioned drawbacks by realizing carbon neutralization and high compression ratio of the composite magnetic powder by improving the structural design has become one of the important problems to be solved by this industry. Disclosure of utility model The utility model aims to solve the technical problem of providing composite magnetic powder aiming at the defects of the prior art. In order to solve the technical problems, one technical scheme adopted by the utility model is to provide composite magnetic powder, which comprises magnetic powder, a thermosetting resin layer coating the magnetic powder and a thermoplastic resin layer coating the thermosetting resin layer. Further, the composite magnetic powder further includes a coupling agent layer formed directly on the magnetic powder. Further, the composite magnetic powder further includes an oxide powder layer disposed between the coupling agent layer and the thermosetting resin layer. Further, the composite magnetic powder further comprises a dispersant layer, and the thermoplastic resin layer is coated. Further, the composite magnetic powder further comprises a metal oxide layer, and a dispersing agent layer is coated on the metal oxide layer. Further, the composite magnetic powder further comprises a lubricant layer, and the metal oxide layer is coated. The winding type solid electrolytic capacitor packaging structure and the manufacturing method thereof have the beneficial effects that the high compression ratio of the magnetic powder can be improved through the technical scheme that the thermosetting resin layer coats the magnetic powder and the thermoplastic resin layer coats the thermosetting resin layer.
