The coil itself is also required to be smaller and more efficient, and many insulated wires are packed in a limited space. Therefore, the insulated wire has a problem that the film is easily damaged by a needle or the like of the automatic winding machine, and a rare short circuit and a ground defect are easily generated. As a measure for solving this problem, an attempt has been made to reduce the coefficient of friction on the surface of the insulated wire so as to make it less susceptible to film damage. As one of the methods, a method of applying a lubricant such as wax on an insulated wire has been used in the past.

必要であった。However, in the above method, it was difficult to control the amount of the lubricant applied, and it was difficult to apply the lubricant uniformly on the surface of the insulated wire. Further, since dust and foreign matters easily adhere to the lubricant applied on the insulated wires, a step of washing with a solvent is required.

This method is a method in which various lubricants such as polyethylene, polytetrafluoroethylene, molybdenum disulfide, boron nitride, waxes and the like are added to an insulating paint in advance and mixed. However, in the case of this method, since the lubricant is insoluble or hardly soluble in the insulating paint, it is extremely difficult to uniformly disperse the lubricant in the insulating paint. The problem has arisen.

In particular, polyamideimide, which is a heat-resistant insulating paint, a lubricant is added to a polyimide or the like, and the above problem is large when lubricity is to be improved.
A heat-resistant insulated wire having a coating made of polyimide or the like has not been obtained.

For example, polyimide, polyamide imide, polyester imide, polyester amide imide, polyhydantoin, polyester, polyurethane, polyvinyl formal Etc. Among them, insulated wires using polyimide or polyamide-imide as an insulating coating material are not particularly effective because they do not have good lubricity as in the present invention.

Millionate MS-50, Dismodular AP Stable are preferred. The amount of the cross-linking agent to be added is usually 10 to 1000 parts by weight based on 100 parts by weight of the solid content of the polyimide coating or the amide imide coating. It is preferably 50 parts by weight to 200 parts by weight because the effects of the present invention will be better exhibited.

Of course, a mixture of the above wax and silicone can also be used. The blending amount of the lubricant is preferably 0.5 to 10 parts by weight with respect to 100 parts by weight of the solid content of the polyimide or polyamideimide coating. If it is 0.5 parts by weight or less, the effect is small, and if it is 10 parts by weight or more, the appearance of the film is poor and the strength is also lowered.

る。Among the above, when a synthetic hydrocarbon wax such as polyethylene is used, the lubricity is good, and the cleaning solvent,
It is more preferable because it is difficult to be extracted by a refrigerant or the like. The second paint, which is a polyimide or polyamideimide paint mixed with a crosslinking agent and a lubricant, must be applied and baked to a film thickness of 0.005 mm or less. If the thickness of the coating exceeds 0.005 mm, the effect of improving lubricity cannot be obtained. The lower limit of the thickness of the coating formed from the second paint cannot be strictly determined because it depends on the combination of materials, but is 0.0005 mm, for example.

Any material such as gold-plated copper may be used. After applying the first paint to the conductor, baking is performed at 400 to 600 ° C. The thickness of the coating formed by the first paint usually varies depending on the size of the conductor and the like. For example, for a conductor having a diameter of 1.0 mm, it is 0.020 to 0.050 mm. Next, after applying the second paint, baking is performed at 400 to 600 ° C.

潤滑性が向上するものと考えられる。The reason why the lubricity is improved in the present invention is estimated as follows. It is believed that the addition of a lubricant to the insulating coating improves the surface lubricity of the coating because the lubricant in the coating bleeds to the surface when the insulating coating is baked. It is considered that the presence of a large amount of lubricant on the surface of the wire coating improves the lubricity of the wire. Therefore, it is presumed that the amount of lubricant bleeding to the surface differs depending on the compatibility between the resin or solvent which is a component of the insulating paint and the lubricant, and the softness of the film during baking, which causes a difference in lubricity. Compatibility with the lubricant is suitable when using the polyimide or polyamide-imide coating of the present invention, and, because the coating is soft during baking (molecular movement of the material is intense),
It is considered that lubricity is improved.

摩擦係数を計算し、潤滑性の評価を実施する。The lubricity is obtained by placing two electric wires on a horizontal base and placing two electric wires on the bottom of the electric wires so that the electric wire of the base and the electric wire of the load come into vertical contact with each other. The force when the load was moved at a moving speed of 10 cm / min was measured, and the equation: Dynamic friction coefficient = F / W [where F is the force (kgW) required to pull the load in the horizontal direction, and W is It is the mass of the load (kg). ] To calculate the dynamic friction coefficient and evaluate the lubricity.
