Abstract
An enamel-covered wire which some magnetic powder are coated onthe surface of and coil have characteristic that the wire surface and coil gaps are covered and filled by adhesive agent containing magnetic powder to be made into coil with magnetic body. The magnetic induction intensity of the coated magnetism wire and coil is better than common enamel-covered wire and coil. It can shorten magnetic path, reduce leakage magnetism and enhance electricity-to-magnetism conversion effeciency. The coated magnetism wire is suitable for making signal wire, winding various electromagnetic induction coil to be used for antenna, motor, transformer, inductor and microwave component etc. It also can be used for making memory and storage component.
Description
The present invention relates to a kind of enamelled wire (hereinafter to be referred as attached enamel paint envelope curve) and coil and method for making and application of surface attachment magnetic material powder.
Utilize insulating varnish to be coated with to invest the enamelled wire of making on the plain conductor surface to be well known, but magnetic coating is coated with the attached enamel paint envelope curve that invests conductive line surfaces and make, and not known by the thread coil of this enamel-cover.
" applied magnetics " (book number: 15212.87) once introduced application and electroplate permalloy line making metal wire memory, its characteristics are that conductive line surfaces is coated with magnetosphere, this magnetosphere conduction.
The enamelled wire that is used for the coiling solenoid claims electromagnetic wire, since the magnetic flux density that simple coil is produced relatively a little less than, in order to strengthen magnetic flux density, the bulk magnetic core is set in coil usually, as the bar magnet in the broadcast receiver, the silicon steel sheet in the transformer etc., volume, weight of electromagnet etc. certainly will have been increased like this.
Task of the present invention provides a kind of novel functional paint envelope curve, it can make by the magnetic flux density of the simple coil of this functional paint envelope curve coiling is strengthened relatively, reduce leakage field, shorten magnetic circuit relatively, improve electromagnetic conversion efficient, reducing magnetic core consumption or cancellation magnetic core in some cases relatively.
Task of the present invention realizes as follows: when modulation insulating varnish, Magnaglo is mixed in the insulating varnish, wherein can by Magnaglo substitute or part substitute in the wire enamel the solids content part as: (magnetic of this moment is equivalent to filler for mica or quartz powder etc., paint vehicle then is equivalent to adhesive), be coated with afterwards and invest conductive line surfaces and get final product, day disclosure special permission communique J07078519A and J7122122A once disclosed with insulating varnish and dosed mica powder making heat-resistant enamelled wire, can be during making with reference to it, but the also manufacture method of reference magnetic coating and electrically-conducting paint.
Magnetic material powder can select as required soft magnetic material and hard magnetic material make as: iron powder, ferrite, crystalline state and amorphous alloy, rare earth alloy etc.
Also the soft or hard magnetic can be mixed according to purposes, needs and use joining when lacquer, its both ratios can be according to big little and definite of required coercive force.For the magnetic of conduction (as iron powder etc.), can take to strengthen ways such as resin or mica powder ratio and make its insulation, also can be coated with insulating barrier earlier, be coated with magnetosphere again.
The ratio of magnetic in coating is for (to see coating process ISBN 7-5025-0645/TQ at the fundamental characteristics that does not influence enamelled wire, 384) and under the working viscosity situation should increase as far as possible, to increase magnetic density, also can be according to definite ratios such as function, costs, ratio should be no less than 50% usually.Granularity of magnet powder should be master's a granularity according to selection 4-6 μ M such as function, costs less than 10 μ M usually, also can select the magnetic of single casting level granularity and 1-20nm as required.The magnetic shape can be selected sphere, elliposoidal, spindle and aciculiform, wherein with sphere for well, also can select as required.
By the still available impregnated insulating paint dipping that is mixed with Magnaglo of the coil of this attached enamel paint envelope curve coiling, impregnating varnish can be with reference to A31-51 among the chemical products handbook ISBN 7-5025-1258-6 when preparation; H32-51; H32-51 and W32-53, with alternative pigment and the part resin composition wherein of magnetic, make the magnetic ratio in its solids content be no less than 50%, and require to get volume to obtain high magnetic density under the situation (referring to coating process ISBN 7-5025-0645/TQ.384) not influencing dipping and impregnating varnish basic (factor), also can determine ratio according to needs such as function, costs, its granularity can be selected the granularity of used attached enamel paint envelope curve with magnetic for use, or selects for use＜granularity of 30 μ M.
In order to improve the magnetic filling rate, also available magnetic at high proportion (＞70% magnetic) is made into putty lacquer with paint vehicle, adopts the way of coiling limit, limit filling that magnetic closely is filled between the slit of coil.To conductive magnetic powder can add fill out insulating material as: mica powder, toner etc. echos insulating requirements until it.
Can be mixed with the adhesive of magnetic by the coil of the different shape of this attached enamel paint envelope curve coiling and be made the bonded permanent magnet of various belt coils.
In the mnemonic of making of magnet ring, require the magnet ring aperture the smaller the better, but too small magnet ring aperture make and sense wire (writing line) and detect line and be difficult for passing is restricted (applied magnetics book number: 15212.87) thereby be directed at device miniaturization.Utilize above-mentioned wire enamel, putty lacquer or be mixed with network node that the binding agent of magnetic makes lead and wrap and be coated with, its effect is equal to lead and passes magnet ring, thereby the above-mentioned difficult problem of solution that can be good, therefore can make storage, memory device (the magnetic ratio in wire enamel, greasy also lacquer and the binding agent should be got volume not influencing under the situation that bag is coated with, bonds, also visual function, cost and determine) with it.
When making the metal wire memory, a kind of plating permalloy line commonly used, the then available attached enamel paint envelope curve of this alloy wire is for it (passing to electric current when coating this enamelled wire so that produce continuous easy magnetizing axis in a circumferential direction).
Utilize the attached enamel paint envelope curve can to make holding wire, the various electromagnetic induction coils of coiling, be applied in, also can replace the permalloy line to make the metal wire memory with this attached enamel paint envelope curve as antenna, motor, transformer, inductance, superconducting magnet etc.
