Description
Technical field
The present invention relates to a kind of magnetic material for being used to manufacture magnetic core.
Background technology
At present, with the reform of information technology, various switch power converters, inverter etc. largely should communications industry
With its utilization rate for exchanging power increasingly obtains the attention of people, and they exchange power utilization in the urgent need to a can improve
The core material of rate, particularly apply to it is high-power, in the electronic product of high current, low-loss core material increasingly by
Communication, the welcome of military industry.
The content of the invention
In order to solve above-mentioned technical problem, it is an object of the invention to provide a kind of high performance magnetic material, with high electricity
Resistance rate, high magnetic permeability, low-loss feature.
To achieve the above object, present invention employs following technical scheme：
A kind of magnetic material, it is compressing by the alloy powder of following components：30~35%Ni, 0.6~0.8%Mo, 1~
2%Si, 1~2%B, 0.1~0.8%Al, surplus are Fe, and powder particle size is -100~+200 mesh；The alloy powder is mixed
Close it is uniform after roast and add phosphoric acid dilution when reaching 170 DEG C~180 DEG C to temperature and be surface-treated, phosphoric acid adds concentration and is
5~9wt ‰, is roasted to drying, adds phenolic resin, and phenolic resin addition concentration is 3~6wt ‰, be further continued for roasting to
Dry；By compressing, pressure is 25~26 tons/cm2；Choose magnetic core annealing, while be passed through in heat treated stove hydrogen and
The mixed gas of nitrogen, 5~15wt% of hydrogen, 550 DEG C of temperature, time 2 h is finally coated in magnetic using epoxy resin paint
The surface of core.
The present invention has advantages below：1st, manufacture craft is simple, simple using equipment；2nd, using the low iron nickel molybdenum powder of valency
End, production cost is substantially reduced；3rd, product has good inductance value, higher quality factor, relatively low power attenuation value；4、
Under higher temperature conditionss, remain to keep excellent soft magnet performance.
Embodiment
The following specific embodiments of the present invention is to make a detailed explanation.

Close it is uniform after roast and add phosphoric acid dilution when reaching 170 DEG C~180 DEG C to temperature and be surface-treated, phosphoric acid adds concentration and is
5~9wt ‰, is roasted to drying, adds phenolic resin, and phenolic resin addition concentration is 3~6wt ‰, be further continued for roasting to
Dry；By compressing, pressure is 25~26 tons/cm2；Choose magnetic core annealing, while be passed through in heat treated stove hydrogen and
The mixed gas of nitrogen, 5~15wt% of hydrogen, 550 DEG C of temperature, time 2 h is finally coated in magnetic using epoxy resin paint
The surface of core.
The soft magnet performance result for the various powder cores that magnetic conductivity is 60 is given in following table, the display present invention has excellent
Soft magnet performance.
It is emphasized that：It the above is only presently preferred embodiments of the present invention, not make any formal to the present invention
Limitation, any simple modification, equivalent variations and modification that every technical spirit according to the present invention is made to above example,
Still fall within protection scope of the present invention.
