Abstract
The production process of electromagnetic wire includes degreasing, plating iron and phosphorizing. On the copper wire surface an iron-plated layer whose thickness is 20-25 micrometers is formed, then the iron-plated layer is phosphorized so as to form the phosphide film insulated electromagnetic wire. Said electromagnetic wire produced by said invented method possesses good high-temp. resisting and freon-resisting porperties, and can be used for producing coil for motor, transformer and freon-resisting motor.
Description
The present invention relates to a kind of method of producing electromagnetic wire, particularly produce the method for the electromagnetic wire can be used for making motor or transformer coil.
The electromagnetic wire that is used as the coil of motor and transformer at present is to be the enamelled wire of insulating material with insulating varnish mostly.The shortcoming of this electromagnetic wire be high temperature resistant, the freon resistant ability is relatively poor, especially when temperature rise is too high, its security performance can descend rapidly, so motor occurs and transformer coil damages the burnout phenomenon that causes because of insulating barrier through regular meeting.
The object of the present invention is to provide a kind of production have good high temperature resistant, fluoride tolerance can the method for electromagnetic wire.
The present invention is achieved in that
(1) allow copper conductor carry out one minute oil removal treatment at ambient temperature in removing oil solution, remove in the oil solution and contain the 40g/l caustic soda, 30g/l sodium carbonate and 10g/l phosphoric acid are received, and electric current is 5A/dm
2
(2) with the copper conductor after the circulating water cleaning oil removing;
(3) under 25-45 ℃ of temperature, with 15-50A/dm
2Electric current plating iron 3 minutes in electroplating solution, form the plating iron layer on the copper conductor surface, contain 500g/l frerrous chloride, 60g/l manganese chloride and 2g/l hydrochloric acid in the electroplating solution;
(4) with the copper conductor after the cleaning of 10% caustic soda solution under the room temperature plating iron, clean with the circulating water under the room temperature more subsequently:
(5) under 60-70 ℃ of temperature, in the zinc nitrate solution that contains 35g/l zinc dihydrogen phosphate and 90g/1, the copper conductor after the plating iron is carried out phosphatization and handled 15 minutes;
(6) clean and oven dry with the water under the room temperature;
(7) under 20 ℃ of temperature, above-mentioned lead was soaked in insulating varnish 30 minutes;
(8) use cloth to wipe with behind the clean surperficial enamelled coating volume in the oven dry.
Advantage of the present invention is:
1, resistance to elevated temperatures is good, can anti-800 ℃ high temperature:
2, mechanical strength height, its intensity can surpass copper conductor itself:
3, the freon resistant performance is good, can be in the medium-term and long-term use of high temperature freon.
The present invention will be further described below in conjunction with embodiment.
Embodiment 1
Copper conductor (circular copper wire or flat type copper wire) is placed on oil removing in the degreasing tank, to improve bond strength.Receive except that containing 40g/l caustic soda, 30g/l sodium carbonate and 10g/1 phosphoric acid in the oil solution.Process conditions during oil removing are: temperature room temperature, electric current 5A/dm
2, 1 minute time.
Clean with the circulating water under the room temperature after the oil removing, remove residual alkali.
Then in plating iron solution, carry out plating iron and handle, obtain the plating iron layer of 20-25 μ m.Contain 500g/l frerrous chloride, 60g/l manganese chloride and 2g/l hydrochloric acid in the plating iron solution, the temperature during plating iron is 25-35 ℃, electric current 15A/dm
2, 3 minutes time.Used anode material is a steel.
Wash with 10% soda lye and circulating water successively after the plating iron, to remove the acid that remains in conductive line surfaces.
The lead of washing is put into the phosphating solution that contains 35g/l zinc dihydrogen phosphate and 90g/l zinc nitrate, under 60-70 ℃ of temperature, carry out phosphatization and handled 15 minutes, form the thick phosphate coating of 20 μ m.
Washing then, oven dry is immersed in 20 ℃ the insulating varnish and is filled, and makes the small pore of phosphate coating be full of insulating varnish, and the lead behind the dipping lacquer uses cloth to wipe with again, remains in surperficial insulating varnish with elimination.
Volume is gone up in the oven dry back, promptly obtains the electromagnetic wire of phosphating coat insulation.
Claims (2)
