Description
Technical field
The present invention relates to the technical field of producing of enamelled wire.
Background technology
Common enamelled wire generally adopts common process, promptly coats common paint film as required at the skin of conductor (copper or aluminium), produces insulation effect, is mainly used in the winding wire of general motor, transformer etc.
All insulating varnish all are not suitable for temperature for the use of the environment below-269 ℃ both at home and abroad at present, therefore can't produce low temperature resistant enamelled wire.Simultaneously, common enamelled wire paint is poor with the tack of conductor, comes off easily, has influenced insulation effect.In addition, common enamelled wire manufacturing cost is than higher, and vibration and noise when the motor of producing moves are bigger, and volume and weight is bigger, and stability is relatively poor relatively.
Summary of the invention
The object of the invention be to invent a kind of can bear-269 ℃ of environment, with the production method of the strong niobium-titanium-nickel alloy modified acetal resin superconductor enameled sheet wire of conductor adhesion.
Technical solution of the present invention is: coat the copper layer outside the Ni-Ti alloy, form composite conductor, be coated in outside the described composite conductor with modified acetal resin, on the coating machine of repeatedly japanning, repeatedly baking, produce enameled sheet wire continuously, described japanning speed is 40m/min, and the furnace temperature of coating machine is 370 ℃～390 ℃.
Each thickness that applies modified acetal resin is the 1-1.2 silk, and the total insulation thickness after the baking is not more than 11.
The inlet temperature of coating machine is that 150 ℃ ± 2 ℃, lower floor's temperature are that 250 ℃ ± 2 ℃, middle level temperature are that 340 ℃ ± 2 ℃, upper strata temperature are 390 ℃ ± 2 ℃.
Adopt technology of the present invention can realize the production of non-resistance superconduction function, do not influence every performance of insulating barrier, this product can be widely used in fields such as superconductor motor, hyperconductive cable core such as NMR.Compare with the motor that conventional enamelled wire is made, the present invention can be carried bigger electric current, produces stronger magnetic field, and under the identical situation of power output, the advantage of the superconducting motor of being produced by the present invention is more outstanding:
1, reduced manufacturing cost;
2, reduce operating cost, increase operational efficiency;
Vibration and noise when 3, reducing the motor operation;
4, volume and weight reduces 4/5;
5, single-machine capacity increases;
6, stability improves;
7, its resistance value is≤160 Ω/km when normality, is 0 Ω/km when-269 ℃ (4K);
8, the every index of product can require below also satisfying under subzero 269 ℃ of states:
(1) puncture voltage 1000V;
After (2) 10 times the mechanical bend insulating barrier wrinkle resistant, do not ftracture;
(3) cold-resistant enzyme.
The mass ratio of Ni and Ti is 1: 8～15 in the described Ni-Ti alloy.
Embodiment
One, production craft step is as follows:
1) Ni and Ti are made into the Ni-Ti alloy according to 1: 8～15 mass ratio.
2) utilize metallurgical equipment outside the Ni-Ti alloy conductor, to coat the layer of copper layer, form composite conductor.
3) with the modified acetal resin be insulating paint, the employing linear velocity is that 40m/min, furnace temperature are 370 ℃～390 ℃ coating machine, the continuous producing method that the enamel-cover process adopts repeatedly japanning, repeatedly toasts, wherein each film thickness should be controlled at the 1-1.2 silk, and total insulation is not more than 11.The inlet temperature of control coating machine is 150 ℃ ± 2 ℃, 250 ℃ ± 2 ℃ of lower floor's temperature, 340 ℃ ± 2 ℃ of middle level temperature, 390 ℃ ± 2 ℃ of upper strata temperature.
4) be the product rolling at last, product inspection
Two, check:
1, the ultralow temperature stability of paint film:
Cryogenic superconductor generally cools off with gas helium, liquid helium or superfluid helium, and cold excessively (pressurization) superfluid helium then is optimum selection.As the enamelled wire that the superconducting motor stator winding is used, requiring heart yearn is superconductor.
2, the tack between paint film and the composite conductor:
Because the general Ni-Ti alloys of using of the superconductor of the superconduction enamelled wire of motor windings more, and the Ni-Ti alloy is poor with the adhesive force of paint resin, coat layer of copper in order just to address this problem outside the Ni-Ti alloy superconductor, the adhesive force of metallic copper and macromolecular material is fine.
