ベルフルオロボリエーテルを含有する絶縁塗料からなる
ものである。This insulated wire has at least one insulating layer on a conductor made of copper or the like, and the outermost insulating layer is made of an insulating paint containing perfluoroboriether.
ここで使用されるベルフルオロポリエーテルは、主鎮中

w-C F , those having a linear structure are preferably used, and among them, those having the general formula (2) are preferred. Also, the average molecular weight is 1,000 to 2
A value of about 0000 is preferably used. If the molecular weight is less than this range, the loss due to evaporation during baking will be large, and if the molecular weight exceeds the above range, it will become solid and difficult to handle, which is not preferred.

あるためである。The amount of such perfluoropolyether added is 0.0
The content is 5 to 20% by weight, more preferably 0.1 to IO% by weight. If it is less than 0.05% by weight, the effect of improving lubricity will not be obtained sufficiently, and if it exceeds 20% by weight, the insulated wire will become sticky and handling will deteriorate, and when used for hermetic motors such as compressors. This is because there is a disadvantage that a large amount of extracted material is extracted into the refrigerant or motor oil.

Any solvent may be used as long as it has a relatively high boiling point and dissolves the resin, such as phenol, cyclohexanone, cresol, xylenol,

が好適に用いられる。The insulating paint thus obtained can be applied and baked directly onto the conductor, but in this case, the adhesion with the conductor will be reduced, so it is usually better to apply and bake it through another insulating film to ensure that the conductor remains intact. This is advantageous in terms of adhesion. In this case, the preferred film thickness ratio is approximately 1/20 to 5/10. On this occasion,
Coating and baking are performed using a normal enamel baking furnace, etc., and the baking temperature is about 250 to 450°C. Further, the coating and baking steps are not limited to one time, but may be repeated several times as necessary until the desired thickness is obtained. Any resin may be used to form the other insulating layer, such as polyurethane, polyvinyl formal, polyester, polyesterimide, polyhydantoin, etc.
Polyamideimide-based, polyesteramide-imide-based, polyhydantoin ester-based, polyesteramide-based, etc. are preferably used.

巻線された信頼性の高いコイル等を得ることができる。The insulated wire thus obtained contains 0.05 to 20% by weight of perfluoroboriether in the outermost insulating layer, so it has high lubricity and good wear resistance. This makes it possible to perform high-speed winding, and even during high-speed winding, it is possible to obtain a highly reliable coil or the like that is tightly wound without causing damage or dropping of the insulating layer.
また絶縁層中にベルフルオロボリエーテルを含有したこ

いものであった。(Hereinafter, blank space) From Table 1, the insulated wires of Examples have excellent abrasion resistance, good heat resistance, low extraction rate, good appearance and flexibility, and a good balance. It became clear that it had good and excellent performance. On the other hand, in Comparative Examples 1 to 4 in which perfluoroboroboriether was not used, the number of reciprocating wear was small and the coefficient of static friction was large, indicating that self-lubricating properties were low and wear resistance was insufficient. found. Further, in Comparative Examples 2 and 4 in which paraffin wax was applied to the surface, the coefficient of static friction was improved, but the extraction rate was high and undesirable. Further, in Comparative Example 5, in which the amount of Bellefur's Robolyether added was less than the range in the present invention, the abrasion resistance was insufficient, and in Comparative Example 6, in which the amount was greater than this range, the extraction rate was high, which is undesirable. In addition, in Comparative Example 7, in which an anti-friction layer was formed by coating and baking an anti-friction agent, the extraction rate was so high that it could not withstand actual use.

Since it contains high lubricity, high-speed winding is also possible, so it is easy to manufacture highly reliable coils without causing scratches or falling off of the insulating layer during high-speed winding. can be obtained. In addition, an insulated wire having an insulating layer containing this perfluoroboriether has excellent heat resistance. Furthermore, when used for hermetic motors such as air conditioners and refrigerators, it is possible to minimize the amount of extraction into the refrigerant or motor oil, and the extracted amount is stable, so there are no problems. It can be used for a wide range of purposes without causing any problems.
