Embodiment Construction

[0013] A high-efficiency soft ferrite core material, prepared from the following raw materials in parts by weight: hydroxyl iron powder 60, ferric oxide 10, manganese oxide 25, zinc oxide 21, silane coupling agent kh5704, silicone resin 5 , polyvinyl alcohol 1, sodium silicate 7, stainless steel powder 0.3, ferrous sulfate 0.5, cryolite powder 0.3, water in proper amount;

[0014] The high-efficiency soft ferrite core material is prepared by the following specific steps:

[0015] (1) Mix and ball-mill hydroxy iron powder, ferric oxide, manganese oxide, zinc oxide and silane coupling agent kh570 for 0.5h, then dissolve the silicone resin with 4 times the amount of acetone, and then add the above coupling magnetic powder to Stir in the organosilicon solution for 0.6h, then dry at 40°C for 1h and pulverize for later use;

[0016] (2) Mix the remaining materials except polyvinyl alcohol and sodium silicate, grind and disperse evenly, then anneal in vacuum at 120°C for 20 minutes,...

Abstract

The invention discloses a high-efficiency soft magnetic ferrite core material. The high-efficiency soft magnetic ferrite core material is prepared from the following raw materials based on parts by weight: 60-65 parts of hydroxy iron powder, 10-15 parts of Fe2O3, 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 polyvinyl alcohol, 7-9 parts of sodium silicate, 0.3-0.4 part of stainless steel powder, 0.5-0.6 part of ferrous sulfate, 0.3-0.4 part of ice crystal powder and appropriate amount of water. The material prepared according to the invention has favorable lamination characteristic and induction, the working efficiency can be improved, the cost is reduced, and the material has favorable social benefit.

Description

technical field [0001] The invention relates to the technical field of ferrite materials, in particular to a high-efficiency soft ferrite 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 m...
