Description
Technical field
The present invention relates to the technical field of magnetically soft alloy material preparation, the preparation methods of specifically a kind of high magnetic conductivity cream.
Background technique
With the increase of electronic product degree of integration, electronic product has more demands for electric power, and requires power supply system
System has reliable electric current and voltage protection and lower fever in the case where high current.
Alloy soft magnetic material direct current biasing is had excellent performance, but resistivity is low, and eddy-current loss is high under high frequency, fever seriously to
It limits and is used under its high frequency, and the trend of high frequency and high power now with electronic device, to the resistance for promoting material
Rate and the calorific value for reducing material are very crucial.Meanwhile the work that alloy soft magnetic inductance generally uses coil and magnetic powder integrally to suppress
Skill mode is realized, and interiors of products copper wire will appear damage if material surface difference excessive compared with sharp or pressing pressure in pressing process
Hurt phenomenon, the bad phenomenon of short circuit is easily caused in device use process, but the inductance value of hypotony product is unable to reach and makes
With requiring.To overcome the weakness, insulating wrapped need to be carried out to alloy powder surface to promote its resistivity, and by improve at
Type reduces the risk of the pressure reduction copper wire damage during production using the compacting stress of material, promotes the property of product
Energy.
So carrying out insulating wrapped to alloy powder promotes pressure required for the insulation of material and the molding of reduction material
Play a significant role to product development, therefore it is very necessary to develop soft magnetic materials magnetism cream technology.
Application publication number CN102942886 Magneto-conductivitygluewater gluewater and its application, be related to a kind of glue with magnetic conductivity and its
Using can use and can obtain more preferable permeability characteristics and reliable in magnetic core gap bonds more particularly to one kind
The application of the glue of adhesion strength and the glue in magnetic core gap bonds.Comprising chemosetting glue, magnetic-particle and
