Description
Technical field
The present invention relates to high temperature superconducting materia field, particularly about a kind of insulating method of conductor of high-temperature superconductor coat.
Background technology
High temperature superconductor technology is developed so far and makes great progress, existing a lot of practical application.At present, be that the application of high temperature super conductive conductor (be also called conductor of high-temperature superconductor coat, two generation high temperature super conductive conductor) of representative is more and more extensive with Y-Ba-Cu-O coating conductor.Conductor of high-temperature superconductor coat has sandwich construction, has very large critical current density, and under low temperature, high-intensity magnetic field, also have good critical current density performance.
In many application scenarios, the surface of high temperature super conductive conductor is needed to have electric insulation layer.Usually tack polyimide film tape is adopted to carry out wrapped electric insulation process (domestic patent CN200510032515) to high temperature super conductive conductor at present.But this electric insulation mode has following problem.(1) wrapped electric insulation has two kinds of modes.Be stained with a tack polyimide film tape along the length direction of high temperature super conductive conductor, more longitudinally by the wrapping of tack polyimide film tape on high temperature super conductive conductor.Another kind is along tack polyimide film tape on the longitudinal lapping of high temperature super conductive conductor.First kind of way, by comparatively large for the local conductor thickness made in tack polyimide film tape overlap, causes the overall out-of-flatness of wire.The second way also can make wire periodically occur out-of-flatness in the longitudinal direction.If tack polyimide film tape degree of overlapping is less, then when width or the thickness of high temperature super conductive conductor, or easily there is the phenomenon of " bottom pour ladle " when the linearity of length direction changes, thus make superconductivity wire out exposed, do not have the effect of insulation.(2) tack polyimide film tape can not keep good contact with between superconductivity wire, particularly when being immersed in liquid nitrogen or liquid helium for a long time, tack polyimide film tape is easily separated with between high temperature super conductive conductor because losing the reasons such as viscosity.If be separated, then increase the possibility that liquid nitrogen or liquid helium enter high temperature super conductive conductor, this may reduce the current capability of wire or wire is ftractureed.This separation also can make to occur around wire space that can be freely movable, to wire fixing, to protect and refrigeration etc. also has adverse effect.(3) tack polyimide film tape is soft, and mechanical property is poor, can not play well protection and fixation to the conductor of high-temperature superconductor coat with sandwich construction.(4) polyimides is very low for the wettability of epoxy resin, and this is also unfavorable for that subsequent cure process epoxy resin is solidificated on high temperature super conductive conductor.(5) thickness of the tack polyimide film tape of current common use comparatively large (being generally not less than 50 microns), this can be equivalent to the density reducing supercurrent.This just causes and in use easily occurs the poor problem that insulate, and greatly limit the application development of this high temperature superconducting materia.
Summary of the invention
Conductor of high-temperature superconductor coat insulating method involved in the present invention directly applies insullac on conductor of high-temperature superconductor coat.The thickness of insulating layer of the conductor of high-temperature superconductor coat utilizing the present invention to prepare is even, avoids the phenomenon that superconductivity wire insulating barrier local is exposed, and has good electrical insulation capability and good mechanical performance.
Conductor of high-temperature superconductor coat involved in the present invention has sandwich construction.Typical conductor of high-temperature superconductor coat, on the base materials such as stainless steel, Ni-W alloy, after the multilayer material such as method growth, barrier layer, resilient coating by physics or chemistry, regrowth in the above has the high temperature superconducting materia of superconductivity, such as ReBCO (Re is rare earth element), is typically yttrium barium copper oxide (YBCO) superconducting coating material.In the preparation process of high temperature superconducting materia, doped chemical or artificial pinining center can also be introduced to improve the performance of high temperature superconducting materia under magnetic field.The protective materials such as silver-colored, golden are covered again subsequently on high temperature superconducting materia layer.Typical conductor of high-temperature superconductor coat sectional view as shown in Figure 1.The thickness of the YBCO conductor of high-temperature superconductor coat of suitability for industrialized production is 50-500 micron at present, and width is 1-30 millimeter, and common YBCO conductor of high-temperature superconductor coat dimensional thickness is 100 microns, and width is 4-12 millimeter.The thickness of conductor of high-temperature superconductor coat is very little, but width is much bigger, and therefore, conductor of high-temperature superconductor coat has very large flakiness ratio, and flakiness ratio is greater than 10 usually.
Because conductor of high-temperature superconductor coat thickness is smaller, in use easily damaging, in order to improve the mechanical performance of conductor of high-temperature superconductor coat, usually reinforcement material can be used to strengthen at conductor of high-temperature superconductor coat.Mode covers a last layer metal material by methods such as plating, such as copper at the outer surface of conductor of high-temperature superconductor coat.Another kind of mode is covered on wide of conductor of high-temperature superconductor coat by reinforcement material by the mode of welding, such as, use brass, stainless steel etc.Also have a kind of mode to be adopt above-mentioned two kinds of reinforcement modes simultaneously.The structural representation of various reinforcement mode as shown in Figure 2.In order to reach good stiffening effect, the thickness of the armature bed of material generally reaches 5-500 micron, and the thickness of the common armature bed of material generally reaches 5-50 micron.
In sum, conductor of high-temperature superconductor coat has very large flakiness ratio, and this makes to become very difficult to the insulation processing of conductor leptoprosopy.The cross section of conductor of high-temperature superconductor coat is close to rectangle simultaneously, and conductor exists wedge angle.For reinforced conductor of high-temperature superconductor coat, the use of reinforcement material makes leptoprosopy have more irregular shape, even also has the existence of concave surface.In the process of coating insullac, compared to plane, at wedge angle or concave part, insullac is difficult to coating equably and gets on, thus has influence on final insulation property.Therefore, the existence of wedge angle and concave surface too increases the difficulty of insulating varnish process.The present invention is directed to the conductor with so large flakiness ratio, propose a kind of method applying insulating varnish.
For achieving the above object, the present invention takes following technical scheme:
An insulating method for conductor of high-temperature superconductor coat, mainly directly applies insullac on conductor of high-temperature superconductor coat, mainly comprises the steps:
1. the conductor of high-temperature superconductor coat before pair coating insullac carries out preliminary treatment.
Conductor of high-temperature superconductor coat carries out preliminary treatment and mainly comprises following several mode:
(1) in the process preparing conductor of high-temperature superconductor coat, the shape of cross section of wire is optimized, makes the cross section of wire more smooth, avoid the appearance of wedge angle and concave surface.Such as, employing cross section is the base material that the present cross section generally used of base material replacement of track type or round rectangle is rectangle.In the process of the reinforced conductor of high-temperature superconductor coat of preparation, the width of the reinforcement material (as brass, stainless steel etc.) of use is less than the width of conductor of high-temperature superconductor coat, avoids the appearance of concave surface.
(2) method of physics or chemistry is adopted to process conductor of high-temperature superconductor coat.The method such as mechanical grinding, laser cutting is adopted to remove wedge angle or the concave surface of conductor of high-temperature superconductor coat cross section.Or adopt the mode of galvano-cautery or chemical corrosion to remove wedge angle or the concave surface of conductor of high-temperature superconductor coat cross section.
(3) conductor of high-temperature superconductor coat surface is electroplated, the process such as physics or chemical deposition, form round and smooth, the fine and close metal level without wedge angle and concave surface of one deck by adjustment treatment process at conductive surface.
2. pair treated conductor of high-temperature superconductor coat carries out the step applying insullac.
The working temperature of conductor of high-temperature superconductor coat is the low temperature below liquid nitrogen temperature (77K) or liquid nitrogen temperature.This requires that the insullac that adopts can keep good mechanical performance, electric property etc. in the cold and hot process of repeatedly " room temperature-low temperature ".And in actual applications, also can be cured process to curing materials such as device epoxy resin such as the coils made by conductor of high-temperature superconductor coat, this requires there is good compatibility between insullac and epoxy resin.Epoxy resin can be solidificated on insullac well, thus plays support, fixing and protection etc. to conductor of high-temperature superconductor coat.Which also limits the selection of the kind of used insullac.
Insullac involved in the present invention, include but not limited to acetal, polyester, modified poly ester, polyurethane, polyester-imide, polyimides, polyamidoimide etc., can be one or more insullacs wherein such as, with the use of, polyester-imide+polyamidoimide etc.Described coating procedure is at least once.
The method applying insullac on conductor of high-temperature superconductor coat of the present invention, comprises and uses felt method, die methods, the techniques such as print process.
The method of described felt method japanning, mainly uses felt clamping plate by together with wide of felt and belt material of high temperature superconduct or contacts side surfaces, is coated in uniformly on wire by paint.Because felt has pine, soft, flexible, crinosity hole, can nib be formed, and scrape off paint unnecessary on wire.In addition, felt absorbs, stores, carries, makes up the effect of paint liquid in addition by capillarity.Felt method japanning structure is simple, easy to operate.The japanning of felt method includes but not limited to these modes following: two pieces of felts are painted conductor of high-temperature superconductor coat two wide respectively simultaneously; Felt is painted on a certain wide of conductor of high-temperature superconductor coat; Two pieces of felts are painted respectively on conductor of high-temperature superconductor coat two leptoprosopy simultaneously; Felt is painted on a certain leptoprosopy of conductor of high-temperature superconductor coat.When painting, can be adopt separately aforesaid way a certain, also can be that mixing adopts several different mode to carry out one or many coating.The paint liquid measure on wire can be regulated by the grip force of felt clamping plate.
The method of described die methods japanning, the mould of die methods japanning is made up of the mould heart and die sleeve two parts, and core rod is that the carbide alloy such as tungsten carbide are made, and die sleeve ordinary steel, brass or stainless steel are made.The mould heart and die sleeve will closely combine, between definitely can not seepage paint liquid.During die methods japanning, it is very important to join mould.Join the size of size to wire of mould, paint solids content, viscosity, the required film thickness of paint, number of times of painting etc. relevant.Die methods is generally applicable to the larger insullac of ratio of viscosities, and the viscosity B coefficent strong adaptability to paint.During die methods japanning, the wire of band paint, through mould, relies on the gap between wire and core rod hole to make paint liquid keep certain thickness.When being coated wire successively through expanding the mould in aperture gradually, just required film thickness can be reached.
The method of described print process japanning, is mainly first coated onto the method for paint by printing on wire.The mode of printing has multiple, and can be directly paint is directly printed onto on wire, also can be by one or more transfer member, lacquer print is brushed on wire.Printed panel or print wheel can be flat board, intaglio plate and relief printing plate.The mode be printed on one side can be adopted, certain wide of each printed circuit cable or leptoprosopy.Also the mode of printed on both sides can be adopted, two wide or leptoprosopy of each printed circuit cable simultaneously.The printing of various mode also can be combined together use.By the quality regulating japanning amount, japanning pressure and other parameters can control paint film.
3. conductor of high-temperature superconductor coat is after coating insullac step, needs step insullac being cured to process.
The solidification of insullac of the present invention, comprises hot curing, ultraviolet (UV) solidifies, from curing modes such as solidization.
The curing mode of described hot curing, the temperature of curing, temperature curve and the control of curing the time have vital impact for conductive line surfaces fineness, color and luster and mechanical performance, hot property and electric property after japanning.First be by the solvent evaporation in paint liquid in the process of curing, be then solidification, form one deck paint film.What occur in solidification process is the chemical change painted, and namely paints the crosslinking curing of base.The performance of the degree of cross linking on paint film plays conclusive impact.In general, stoving temperature is higher, and cross-linking and curing reaction is faster.Also there is conclusive impact time of curing on crosslinking curing.But for conductor of high-temperature superconductor coat, if stoving temperature is too high, the performance of conductor of high-temperature superconductor coat can be affected.In general, stoving temperature is not higher than 600 DEG C.Particularly the reinforced high-temperature superconducting coating of tin welding is used for some, require that stoving temperature must below the fusing point of tin especially, otherwise can on the impact of damaging property of conductor.
The curing mode of described ultraviolet light polymerization, mainly by the irradiation of the ultraviolet light of suitable wavelength, the light trigger decomposed in paint forms free radical, and then causes the unsaturated-resin in painting and the solidification of reactive diluent interlinkage.The ultraviolet light polymerization time is exceedingly fast.Ultraviolet-cured paint be used for conductive line surfaces coating, and in be heating and curing paint with the use of.
The described curing mode from solidization, refers to oneself drying and forming-film of the paint after coating.Volatile dry, oxidation drying, normal temperature cure drying etc. are comprised several from dry curing mode.General all long from curing time of solidization, and compared to another two kinds of curing modes, after solidification paint heat-resisting, solvent resistant, chemical-resistance, mechanical performance and electric property are less better.
Reach the performance requirement of required each side, the insulating method of conductor of high-temperature superconductor coat is often needed to " japanning-solidification " process of carrying out repeatedly.Can adopt in applied atop mode one or more carry out the insulating varnish coating of one or many after be cured again." japanning-solidification " repeatedly can adopt same insullac and same curing mode, also can adopt different insullacs and different curing methods.
Also can not carry out pretreated step to conductor of high-temperature superconductor coat, directly conductor of high-temperature superconductor coat be carried out to the process of " japanning-solidification ", to reach the japanning problem solving wedge angle or concave surface.
By adopting the insulating method of coating insullac of the present invention, the problem of the minor insulation weakness adopting lapped insulation process to run into can be solved.Use insulating method tool of the present invention to have the following advantages, insullac can realize all standing to conductor of high-temperature superconductor coat, fundamentally avoids the possibility that wire is exposed.The thickness of insullac is even, and the electric insulation paint film of several microns just can realize good electric insulating effect, and puncture voltage can reach more than 1000V, and has good mechanical performance, can play a protective role to conductor of high-temperature superconductor coat.Between electric insulation paint film and conductor of high-temperature superconductor coat, close contact together, thus can not the generation of separative phenomenon.Electric insulation paint film also has well heat-resisting, solvent resistant, chemical-resistance, and has good compatibility with epoxy resin.For the conductor of high-temperature superconductor coat having carried out electric insulation process, can direct coiling etc., be also suitable for being cured with epoxy resin.
