Problems solved by technology

However, the general organic or inorganic coating layer has non-magnetic characteristics. After compounding with metal magnetic particles, it will also reduce the saturation magnetization of the material to a certain extent. Loss while maintaining high density and saturation magnetization is the focus of current research

Abstract

The invention discloses a nanometer magnetic core material. The nanometer magnetic core material is prepared from the following raw materials in parts by weight: 60-65 parts of iron carbonyl powder, 10-15 parts of iron trioxide, 25-27 parts of manganese oxide, 21-23 parts of zinc oxide, 4-5 parts of silane coupling agent kh570, 5-7 parts of organic silicon resin, 1-2 parts of polyving akohol, 7-9 parts of sodium silicate, 1-2 parts of nickel oxide, 0.4-0.5 parts of antimonous oxide, 0.3-0.4 parts of expansion mica powder and a proper amount of water. The nanometer magnetic core material has the characteristics of simple method and low cost; and in addition, the prepared material has the effects of high magnetic conductivity, high strength, high thermal resistance, fireproof property and the like, so that the requirements of conventional electric appliances on the magnetic core material can be satisfied.

Description

technical field [0001] The invention relates to the technical field of ferrite materials, in particular to a nanometer magnetic core material. Background technique [0002] Soft magnetic material is a kind of magnetic material with low coercive force and high magnetic permeability. Under the action of external magnetic field, soft magnetic material shows the characteristics of easy magnetization and easy demagnetization. Soft magnetic material is used as magnetoelectric conversion It is one of the important functional materials in the field, and has a wide range of applications in the fields of electronic equipment, communications and electrical appliances. With the popularization of digital TV sets and notebook computers, electronic equipment is becoming lighter, thinner, and miniaturized. This will inevitably reduce the size of the power supply, and put forward higher and stricter requirements for the power supply. Due to the characteristics of high saturation magnetic in...
