Abstract

The invention provides a method for manufacturing a high-performance permanent magnet. The method includes: (1) providing rare earth magnetic powder; (2) adjusting the particles of the rare earth magnetic powder so that the rare earth magnetic powder particles are kept at a single domain size; (3) ) carry out surface treatment to the rare earth magnetic powder; (4) provide rubber magnetic powder and additives to mix with the rare earth magnetic powder; (5) process plasticization, kneading, molding, and magnetization into finished products, so that the final magnetic glue has good Excellent rubber and plastic characteristics and magnetic properties, and solve the problems in the prior art that it is difficult to mix magnetic powder with rubber and plastic materials to make finished products, and it is easy to drop powder and rust.

Description

technical field [0001] The invention relates to a high-performance permanent magnet manufacturing technology, in particular to a manufacturing method of a flexible magnet used in various fields to provide permanent magnetic force. Background technique [0002] High-performance permanent magnets and ferrite magnetic materials are a class of important magnetic materials that keep pace with metal magnetic materials. Their application fields have spread throughout all aspects of the national economy, and they have strongly promoted the development of radio electronics, communications, microwave electronics, and information storage. The rapid development of science and technology such as processing and processing. In the past ten years, the annual growth rate of international and domestic production and sales of ferrite magnetic materials has been above 10% and 20% respectively. With the acceleration of the transfer of the magnetic material industry and motor, transformer, elect...
