本発明は、電気絶縁用樹脂組成物及び絶縁電線に関する

に応じてモータやトランスなどの各種の用途に使用され
ている。Conventionally, insulated wires (hereinafter referred to as enameled wires) are made by coating, baking, and bonding synthetic resin compositions such as polyvinyl formal, polyurethane, polyester, polyesterimide, and polyamideimide onto conductors, depending on the characteristics of each paint. It is used in various applications such as motors and transformers.

されている。In recent years, electrical manufacturers that use enamelled wire have begun to introduce automatic high-speed winding machines to streamline the manufacturing process of devices, and as a result, during the winding process, the enamelled wire is subject to wear due to friction, impact, etc. is susceptible to mechanical damage, leading to layer shorts, grounding defects, etc., and increasing the defective rate.In order to reduce such mechanical damage, Enamelled wire is requested.

討されるようになってきている。Enamelled wire alone has poor lubricity, so as a method to solve this problem, conventional methods include applying liquid paraffin, solid paraffin, insulating oil, wax, etc. on the enamelled wire, which has excellent mechanical strength and abrasion resistance. A method of overcoating with nylon, etc., was applied. However, among these methods, in the method of applying paraffin, etc., paraffin, oil, and wax are removed when the enameled wire is wound around the motor or transformer and then varnished with impregnated varnish or casting resin.
Due to poor affinity with impregnated varnish and casting resin, there have been problems in that poor adhesion and voids are likely to occur. Also,
In the method of overcoating with nylon, etc., the same conditions (furnace temperature, baking speed, etc.) as for the baking line of the undercoat enameled wire are used.
The range of use has been limited due to the inability to bake at high temperatures, resulting in decreased productivity and the deterioration of enameled wire characteristics such as cut-through temperature.Furthermore, the price is high. Therefore, a method of overcoating with a synthetic resin paint for enameled wire in which wax or low molecular weight polyethylene is dispersed under the same conditions as the undercoat paint is being considered.

チレンが分離して（るという欠点があった。However, waxes and low molecular weight polyethylene
Due to the poor compatibility with the synthetic resin for enameled wire and the solvent, it is difficult to disperse it in the synthetic resin paint for enameled wire, and even if you try to force it to disperse by strong stirring or other methods, it will be difficult to disperse. The drawback was that waxes and low molecular weight polyethylene separated over time.
本発明は、前記従来技術の欠点を解消し、滑り性に優れ

ことにある。The present invention solves the drawbacks of the prior art, and provides an electrically insulating resin composition that has excellent slip properties, good lubricant dispersibility, excellent surface stability, and can form a self-lubricating film. be.

メル線に関する。The present invention provides (A) 0.1 to 10 parts by weight of partially saponified ester wax and (B) 0.1 to 10 parts by weight of low molecular weight polyethylene having a number average molecular weight of 5,000 or less, per 100 parts by weight of the resin content of a synthetic resin coating for enameled wire. The present invention relates to an electrically insulating resin composition containing 1 to 10 parts by weight, and an enameled wire obtained by coating and baking the same on a conductor directly or via another insulator.
本発明に用いる部分けん化エステルワックスとしては、

、ヘキストワックスＦＬが挙げられる。部分けん化エス
テルワックス以外のワックスは、（Ｂ）成分の低分子量
ポリエチレンとの相溶性が悪く、分散性が劣る。The partially saponified ester wax used in the present invention includes those represented by the structural formula [wherein R represents a hydrocarbon group having 28 to 32 carbon atoms] and derivatives thereof, with those having a molecular weight of 800 being preferred. . For example, manufactured by Hoechst Japan ■, product name Hoechst Wax ○P, Hoechst Wax X55, Hoechst Wax 0, Hoechst Wax OM
, Hoechstwax FL. Waxes other than the partially saponified ester wax have poor compatibility with the low molecular weight polyethylene of component (B) and have poor dispersibility.
部分けん化エステルワックスは、塗料の樹脂分１００重
量部に対して０．１〜１０重量部添加される。添加量が
０．１重量部未満では、滑り性の効果が劣り、１０重量
部を越えると、エナメル線の外観が劣る。The partially saponified ester wax is added in an amount of 0.1 to 10 parts by weight per 100 parts by weight of the resin content of the paint. If the amount added is less than 0.1 part by weight, the slipping effect will be poor, and if it exceeds 10 parts by weight, the appearance of the enameled wire will be poor.
次に、（Ｂ）成分として配合される低分子量ポリエチレ

重量部配合される。添加量がＯ，１重量部未満では滑り
性の効果がなく、１０重量部を越えると、エナメル線の
外観が極端に低下する。Next, the low molecular weight polyethylene to be blended as component (B) is not particularly limited as long as it has a number average molecular weight of 5000 or less. When the number average molecular weight exceeds 5000, dispersibility is poor. Moreover, this low molecular weight polyethylene is 0.1 to 10 parts by weight per 100 parts by weight of the resin content of the paint.
Parts by weight are added. If the amount added is less than 1 part by weight, there will be no effect on slipperiness, and if it exceeds 10 parts by weight, the appearance of the enameled wire will be extremely deteriorated.
部分けん化エステルワックスのみをエナメル線用合成樹
脂塗料に分散させようとしても分散状態が悪く、粗い不
均一分散系となり、短時間に層分離してしまう。Even if an attempt is made to disperse only a partially saponified ester wax into a synthetic resin coating for enameled wire, the dispersion state is poor, resulting in a rough, non-uniform dispersion system, and the layers separate in a short period of time.
一方、低分子量ポリエチレンのみを同様にエナメル線用
合成樹脂塗料に分散させた場合には、分散安定性が劣る
ばかりでなく、得られたエナメル線表面に大きな凹凸が
生じて、著しく外観が低下する。On the other hand, when only low molecular weight polyethylene is similarly dispersed in a synthetic resin paint for enameled wire, not only is the dispersion stability poor, but the surface of the resulting enameled wire becomes highly uneven, resulting in a marked deterioration in appearance. .

自己潤滑性にも優れることが見出された。Surprisingly, however, when the above partially saponified ester wax and low molecular weight polyethylene are used together, the dispersibility is significantly improved, and a stable dispersion state is maintained even after heating. It was found that it has good properties and also has excellent self-lubricating properties.

いが、特に制限はない。As a method for dispersing partially saponified ester wax and low molecular weight polyethylene in synthetic resin paint for enameled wire, first, because it does not disperse well even if added directly.
A preferred method is to disperse partially saponified ester wax and low molecular weight polyethylene in a solvent, add this to a synthetic resin coating for enameled wire, and disperse. Examples of the solvent include aromatic hydrocarbons such as cresol and xylene. The content of partially saponified ester wax and low molecular weight polyethylene in the solvent dispersion is preferably 1 to 20% by weight, but is not particularly limited.

線を製造することも可能であるが、他の絶縁物を介して
塗布、焼付けてオーバーコートし、ダブルコート線とし
て用いる方が好ましい。Although it is possible to manufacture an enamelled wire by directly baking the resin composition of the present invention onto a conductor, it is preferable to apply it via another insulator and bake it to overcoat it and use it as a double-coated wire.
下地用塗料と同じベース樹脂を用いた塗料に部分けん化

合成樹脂塗料の焼付条件と同一条件で目的とする自己潤
滑性ダブルコート線を得ることができる。By using the resin composition of the present invention, which is a paint made from the same base resin as the base paint, partially saponified ester wax and low molecular weight polyethylene, it is possible to achieve the desired baking conditions under the same baking conditions as synthetic resin paints for enameled wires. A self-lubricating double-coated wire can be obtained.
