Problems solved by technology

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

Abstract

The invention relates to a magnetic composition and a preparation method of the magnetic composition. The preparation method comprises the steps of sequentially adding 1,3,5-triglycidol-S-triazinetrione and dibutyltin oxide in 2-hexanone, then adding ethoxylated trimethyol propane triacrylate and linseed oil after uniform mixing, proceeding reflux reaction for three hours, finally adding a mixture formed by a packing system and acrylic prepolymer, proceeding reflux reaction for one hour, and removing a solvent through volatilization so as to obtain the magnetic composition. According to the magnetic composition and the preparation method, disclosed by the invention, raw materials are easy to get, complex reaction in the prior art is not needed, the prepared magnetic composition has excellent mechanical property and a good solidification effect, and ingredients cooperate with one another to promote organic chain segments to move so as to form a stable structure, so that the brittleness resistance of a system is further increased, the toughness and the thermal resistance of materials are increased, and unexpected effects are obtained.

Description

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...
