technical field [0001] The invention belongs to the technical field of magnetic composite materials, and in particular relates to a magnetic composite composition and a preparation method thereof, which can obtain magnetic materials with high toughness and high heat resistance. Background technique [0002] The rapid development of digital communication technology and optical fiber communication has continuously updated and eliminated traditional analog communication equipment. Most of the various power transformers used in the communication field work under low magnetic flux density. At this time, the magnetic permeability of the material plays a major role. . Nowadays, the research on nanocomposite materials has been developed rapidly. Unlike nanocrystalline materials and nanophase materials composed of a single phase, nanocomposite materials are composed of two or more Gibbs solid phases in at least one direction in nanometer Composite materials made of grade-size compos...

Bending is a direct reflection of material toughness. For flexural reliability, IPC has proposed an evaluation method for the number of flexural fractures. However, this test force method takes a long time, sometimes several months, and is very important for the research and development of new products. It is extremely unfavorable, so the Japanese academic community proposed to use the M1T method to test the single-point bending resistance of the material to evaluate the bending resistance of the material. This method has the advantage of rapid test results, but it is greatly affected by the processing accuracy of the bending head, and the data is not good. Stablize

[0003] High-permeability alloy materials are mainly used in magnetic shielding, leakage switches, miniaturized high-frequency switching power supplies and high-density recording devices. High-permeability materials have always been the focus of research on soft magnetic materials at home and abroad, and there is a great market demand ; but there are some defects in the existing materials, which are mainly reflected in: only pursuing the high magnetic flux rate of the magnetic powder, ignoring the environment when it is used, and the compatibility with other components; the particle and organic component in the composite magnetic material Poor compatibility and many interface defects; in order to ensure the magnetic properties of existing magnetic materials, a large amount of magnetic powder is added, resulting in poor mechanical properties and heat resistance of composite materials
