Technical effect: present invention japanning process is simple, avoids multicoat and causes mixed paint linear to influence enamel-cover
Can, the enameled wire excellent combination property of preparation.
The technical solution that the present invention further limits is:
Further, single side film thickness is greater than or equal to plane film thickness at the angle polyimide insulative coating R.
Another object of the present invention is to provide a kind of systems of new-energy automobile kinetic energy recycling high power inductance electromagnetic wire
Standby technique uses die methods coating polyimide insulated paint in copper conductor surface, specifically: utilize japanning die by solid content
30% or more polyimide insulative paint point, 10 passages are uniformly on the copper conductor, and japanning amount 0.01mm, passes through baking per pass
The solvent in polyimide insulative paint is set to volatilize, film curing.
A kind of preparation process of preceding new-energy automobile kinetic energy recycling high power inductance electromagnetic wire, polyimides are exhausted
Edge paint is to use 45%N- methyl pyrrolidone and 20% dimethylbenzene as solvent, is diluted and is made to polyimide resin.
The beneficial effects of the present invention are:
(1) there is the insulated paint made of retarder thinner and polyimide resin through overbaking, the paint film being formed by curing in the present invention
Preferable flexibility, and there is certain self-lubricating function on surface, strengthens the processable degree of enamelled wire surface paint film, and the paint
Film forms enameled wire product heatproof index after solidifying reaches 220 DEG C or more；
(2) the paint film adherency and toughness when enameled wire prepared by the present invention is bent are higher than ad eundem by 50% or more；
(3) angle enameled wire R prepared by the present invention single-face lacquering thickness is not less than plane japanning thickness, and four angle consistency are good.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention；
Fig. 2 is japanning die schematic diagram of the present invention；
Wherein: 1, polyimide insulative coating；2, copper conductor；3, the angle R；4, japanning die.
Specific embodiment
A kind of new-energy automobile kinetic energy provided in this embodiment recycles high power inductance electromagnetic wire, structure as shown in Figure 1,
Including copper conductor 2, polyimide insulative coating 1 is coated with outside copper conductor 2, the film thickness of polyimide insulative coating 1 is
0.10mm, single side film thickness is greater than or equal to plane film thickness at the angle R 3 of polyimide insulative coating 1.Copper conductor 2
Area of section is in 35mm2 or more.
The preparation process of above-mentioned electromagnetic wire uses die methods coating polyimide insulated paint on 2 surface of copper conductor, specifically
Are as follows: utilize japanning die 4(as shown in Figure 2) divide 10 passages uniformly in institute in the polyimide insulative paint of 30% or more solid content
It states on copper conductor 2, per pass japanning amount 0.01mm, since the first passage, 4 intermediate throughholes size of japanning die increases by road
0.01mm makes the solvent in polyimide insulative paint volatilize, film curing by baking (400 DEG C of temperature).
Common enameled wire product is respectively by the cutting of GB/T 7095, bend test standard: cutting≤1 times of line width, 4 times
Line width is vertical not to crack around bending paint film, and≤1/4 times of line width of enameled wire product actual measurement cutting of the invention, 1.5 times of line widths are stood and go for a stroll
Bent enamel-cover does not crack.
After enameled wire sample of the present invention stretches 10%, 180 ° of 2 times of line width bending paint films do not crack.Thickness direction right-angle bending
Afterwards the exception such as drum, bubble is played without paint film within high temperature scolding tin 5 seconds for 450 DEG C.Breakdown voltage improves 1 times than ad eundem enameled wire pressure voltage,
Actual breakdown voltage value reaches 5.0KV or more.The big section enameled wire of 35mm2 or more of the present invention, carried out with the diameter of 1 times of width it is small
Times diameter it is vertical around, and to the 90 degree bendings of end coating removal after, then carry out 450 DEG C of high temperature scolding tin 5 seconds, coil is without influence coil after processing
Can it is bad.
In addition to the implementation, the present invention can also have other embodiments.It is all to use equivalent substitution or equivalent transformation shape
At technical solution, fall within the scope of protection required by the present invention.
