Abstract

The invention provides a Mn-Zn ferrite magnetic material, and relates to the field of soft magnetic ferrite materials. The Mn-Zn ferrite magnetic material is prepared from main ingredients and auxiliary ingredients, wherein the main ingredients mainly comprise, by weight, 45.6-63 parts of ferric oxide, 16-25 parts of zinc oxide and 22-29 parts of manganese oxide, and the auxiliary ingredients comprise, by weight, 3-10 parts of calcium carbonate, 2-4 parts of iron boron, 0.5-1.5 parts of titanium dioxide, 0.5-1.5 parts of tin antimony oxide, 0.2-0.7 part of gadolinium nitride, 2-7 parts of citric acid, 3-7 parts of carboxymethylcellulose, 2-4 parts of a 5% polyvinyl alcohol solution, 6-8 parts of urethane acrylate and 0.01-0.05 part of niobium pentoxide. The invention further provides a preparation method of the Mn-Zn ferrite magnetic material. The Mn-Zn ferrite magnetic material has both high permeability and high magnetic interference resistance.

Description

technical field [0001] The invention belongs to the field of soft magnetic ferrite materials, in particular to a Mn-Zn ferrite magnetic material. Background technique [0002] Ferrite is a non-metallic magnetic material, also known as magnetic ceramics. As early as the Spring and Autumn Period and the Warring States Period in my country, there was a record of "kindness stone calls iron". Among them, the so-called "compassion stone" is what is called magnetite in modern times, which is a kind of ferrite. Its main component is Fe3O4, which can be called natural ferrite. So far, ferrite magnetic materials have been widely used in broadcasting, communication, radio, television, audio-visual technology, electronic computer technology, automatic control, radar, aerospace and satellite communication, instruments, meters, printing, display, biomedicine, optoelectronic technology and many other high-tech field has been widely used. [0003] Soft magnetic ferrite material is the fi...
