（従来の技術）
近年、絶縁電線を用いてコイル等を作る工程において、
その作業性を高める意味合いから巻線の高速化か検討さ
れており、表面潤滑性を持った絶縁電線か要望されてい
る。[Detailed Description of the Invention] (Prior Art) In recent years, in the process of making coils etc. using insulated wires,
In order to improve workability, speeding up the winding is being considered, and insulated wire with surface lubricity is desired.
その方法として、■絶縁電線の表面に潤滑剤、たとえば

ートする方法などが用いられている。The methods include: - A method of applying a lubricant such as paraffin or WAUX to the surface of the insulated wire. A method of applying an aqueous dispersion of polyethylene to the surface (a method of applying a polyethylene aqueous dispersion to the surface of the insulated wire (nylon with a lubricating component added to the surface of the stepped insulated wire). Methods such as overcoating with resin are used.
前記従来法の中で、■の方法では電線上に潤滑剤を均一
に塗布することに問題があり。Among the conventional methods described above, method (2) has a problem in uniformly applying lubricant onto the electric wire.
更にこれらの中で比較的分子量の小さいものを特に密閉

因になる。又、（りの方法では、ポリエチレンのように

れている。Furthermore, among these, those with relatively small molecular weights may cause contact failure, especially when applied to electrical wires for closed relay coils. In addition, in the method described above, if a material with a large molecular weight such as polyethylene is used, powder is likely to be generated during the actual winding process, which often causes wire breakage.
又、■の方法ては、その潤滑性（動ｙｌ擦性）か前者の

その塗料は潤滑剤を塗才１中に分散しているものである

、特に線径か細＜ （０，１ｍｓ以下゛）なると使用か
困難である。In addition, method (■) has inferior lubricity (dynamic friction) compared to electric wires coated with the former, and
Since this paint has a lubricant dispersed in the coating material, the coating method is limited to the die method, and it is difficult to use especially when the wire diameter is small (less than 0.1 ms). It is.
よって、これらの闇題点を改良するために検Ｊ・ナシた

脂などとの相溶性か悪くなり、得られる絶縁電線の外観
に荒れを引き起こすため不適当となる。Here, the reason why the average molecular weight of the polyolefin compound used is 200 to 2000 is that the average molecular weight of the polyolefin compound used is 200 to 2000.
If it is less than that, the lubricating effect is insufficient, and seizing tends to volatilize or decompose due to the heat of time, making it unsuitable. In addition, if the average molecular weight exceeds 2000, it becomes almost insoluble in general solvents, especially those used for insulating materials, etc. It is unsuitable because it has poor compatibility with polyurethane resins, polyester resins, polyamide resins, formal resins, acrylic resins, etc., and causes roughness in the appearance of the resulting insulated wire.

However, it is especially preferable to react the active hydrogen atom in one molecule with the base resin beforehand, as this will improve the storage stability of the coating and provide stable lubricity to the resulting wire. j-I can do it.

It is necessary to have a weight of 5 to 50. If the amount is less than 0.51 parts, stable lubricity cannot be achieved.On the other hand, if it exceeds 50 parts, the properties of the baked coating may be affected, such as hardness or appearance. , causing problems with thermal characteristics, etc.
