しやすいため溶剤で洗浄する行程も必要であった。In recent years, along with the miniaturization and high performance of devices, miniaturization and high efficiency of the coil itself have been demanded, and many insulated electric wires have been packed in a limited space. Therefore, there is a problem in that the insulated wire is easily damaged by a needle of an automatic winding machine or the like, and a rare short circuit or a ground failure is likely to occur. As a remedy for this problem, an attempt was made to reduce the friction coefficient on the surface of the insulated wire so that it is less susceptible to film damage. As one of them, a method of applying a lubricant on an insulated wire has been performed from the past. However, in the above method, it was difficult to control the amount of lubricant applied, and it was difficult to apply the lubricant uniformly on the surface of the insulated wire. Furthermore, since dust and foreign matters are likely to adhere to the lubricant applied on the insulated wire, a step of washing with a solvent is also necessary.

きないという問題点がある。As another method, a method of imparting lubricity to an insulated wire has been studied. This method is a method in which various lubricants such as polyethylene, polytetrafluoroethylene (hereinafter abbreviated as PTFE) molybdenum disulfide, polon nitride and waxes are added and mixed in advance with the insulating paint.
However, in the case of this method, it is extremely difficult to disperse the lubricant evenly in the insulating paint because it is insoluble or poorly soluble in the insulating paint. Is occurring. In particular, the friction coefficient of the lubricant itself is the smallest among various lubricants, and the most effective effect is expected to obtain the low friction coefficient.
Regarding FE, JP-A-55-21885 and JP-A-62-1760
However, there is a problem in that it cannot be uniformly dispersed in the insulating coating and the friction coefficient of the insulating coating cannot be lowered.

付けた絶縁電線の製造法を発明するに至った。The inventors of the present invention have made extensive studies as to how to uniformly disperse the fluororesin in the insulating coating material in order to solve the above problems, and the surface tension at 25 ° C. was mixed with the fluororesin in a solvent of 30 dyn / cm or less. The inventors have invented a method for producing an insulated wire in which a mixed solution is dispersed in an insulating paint and then the insulating paint is applied and baked directly to a conductor or through an insulating layer.

TFE) Polyvinylidene fluoride (PVdF) Polyvinyl fluoride (PVF), etc. Among them, since PTFE has the smallest friction coefficient, it has a large effect of lowering the friction coefficient on the surface of the insulated wire and is therefore preferable. The particle size of the fluororesin powder is not particularly limited, but is preferably 10 μm or less, and more preferably 5 μm or less in consideration of disconnection due to clogging of the fluororesin powder in the die.

The surface tension at 25 ° C must be 30 dyn / cm or less. At 30 dyn / cm and above, the contact angle with fluororesin is 50-60.
It becomes difficult to prepare a uniform mixed solution because the wettability becomes worse when the temperature becomes above °. When it is 30 dyn / cm or less, the wettability with the fluororesin is improved, and a uniform mixed solution can be prepared.

絶縁電線が得られた。 In Comparative Examples 3 and 4, the surface tension of the solvent was 30 dyn / cm or more, and the wettability with PTFE was poor, so the mixed solution of PTFE and the solvent was not uniform. Therefore, after that, the mixed solutions prepared in Comparative Examples 2 and 3 were added to the polyamideimide coating to attempt dispersion, but it was not possible to uniformly disperse PTFE. On the other hand, the solvent used in Examples 1 to 4, that is, the solvent having a surface tension of 30 dyn / cm or less, has good wettability with PTFE, and thus a uniform mixed solution was obtained. afterwards,
The paint in which the mixed solution was added to the polyamide-imide paint was also able to disperse PTFE uniformly. Lubricated polyamide-imide wire was prepared using the paint, and an insulated wire having good lubricity and wear resistance was obtained.
実施例3,5,6,7よりPTFEが潤滑性、摩耗性向上に最も
効果があることがわかる。From Examples 3, 5, 6, and 7, it can be seen that PTFE is most effective in improving lubricity and wear resistance.

0PHRでは皮膜強度が弱くなり摩耗性が劣ってくることが
わかる。According to Comparative Example 5, Examples 8, 9, 10, 11 and Comparative Example 6, when the amount of PTFE added was 1 PHR or less, the lubricity and wearability were not sufficient.
It can be seen that at 0 PHR, the coating strength becomes weak and the wear resistance becomes poor.
以上の実施例、比較例から明らかなように、本発明に
よる絶縁電線は、従来の絶縁電線に比べ、潤滑性、摩耗
性に優れ、その工業的価値は大きい。As is clear from the above Examples and Comparative Examples, the insulated wire according to the present invention is superior in lubricity and wear resistance to the conventional insulated wire and has a great industrial value.
