いる。Rationalization is rapidly progressing in the coil winding process for motors, transformers, etc., and high-speed automatic coil winding machines are being actively introduced. In the process of high-speed self-winding, the wire's surface coating is often damaged, resulting in a high rate of defects such as layer shorts, and there is a strong desire for insulated wire with characteristics that can withstand this. There is.

コートする方法が用いられてきた。Conventionally, methods for improving the machining resistance of so-called insulated wires include applying oil to the coating of the insulated wire, applying and baking a lubricating resin such as nylon, or applying polyamide-imide resin with excellent mechanical performance. Overcoating methods have been used.

。However, even if oil is applied, it is impossible to expect a significant improvement in workability. However, overcoating with nylon or polyamideimide resin requires a large number of steps and the resin cost is high, which significantly increases the cost of the insulated wire and improves its properties. Although it is good, there are restrictions on its use and it is not widely used.

本発明者等は上記の事情にかんがみ、耐加工性に優れし
かもコストの低い絶縁電線を得るため鋭意研究の結果、
本発明を達成する奔命に至ったものである。In view of the above circumstances, the present inventors conducted extensive research to obtain an insulated wire with excellent processing resistance and low cost.
This led to the quest to achieve the present invention.

This is an insulated wire characterized by coating a conductor with paint directly or through another insulator and baking it.

ある。First, the melamine cyanurate compound used in the present invention is obtained by associating 1 mole of melamine with 1 mole of isocyanuric acid or/anuric acid as shown in the following formula.
9, · ° Axis, 7N #4I4z Next, the electrical insulation paint used in the present invention is a resin paint that is generally used, such as a polyester resin paint, a polyurethane resin paint, a polyimide resin paint, a polyesterimide resin paint, or a polyamide resin paint. Gude resin paint, polyimide resin paint, formal resin paint, epoxy resin paint, etc. can be used. Furthermore, the solvents for these paints include organic solvent-based paints such as cresol, pond water-based solvent paints,
Furthermore, it can also be applied to non-solvent type paints and self-fusing paints. A specific example of the melamine cyanurate compound is the trade name (MCA) manufactured by Yuka Melamine Co., Ltd.

る。The reason for limiting the amount of the melamine cyanurate compound to 0.1 to 5 parts by weight per 100 parts by weight of the resin content of the insulating paint in the present invention is that it is 0.1 or less!・・This is because the effect of addition and blending cannot be seen with □, and if the amount exceeds 5 parts by weight, the processing resistance of the resulting insulated wire will not improve much by increasing the amount, and on the contrary, there is a risk of causing abnormalities on the coating surface of the insulated wire. .
