剤を添加する方法等が用いられていた。Insulated wires made by coating and baking polyurethane paint, polyester paint, etc. on conductors are widely used as coils for electrical and electronic equipment, etc., but they prevent processing deterioration during coil winding and breakage when wires are fed out, and improve winding properties. In order to improve this, it is necessary to lubricate the surface of the insulating film and improve the mechanical strength of the film to increase its wear resistance. For this reason, conventional methods have been to apply a lubricant such as liquid paraffin or refrigerating machine oil to the surface of the insulating film, or to apply a lubricant such as nylon (6-
A method of coating the outer periphery of an insulating film with nylon, 6-6 nylon, etc. and then applying a lubricant, or a method of adding a lubricant to the insulating coating were used.

が低下してしまうという間層かあった。However, as electrical and electronic equipment has become smaller and more sophisticated in recent years, organic gases generated from insulating materials have attracted attention as a cause of equipment malfunction, and it is desirable to reduce the generation of such organic gases as much as possible. 6 For example, in relay circuits, liquid paraffin, which is applied as a lubricant to the surface of the insulating film, decomposes due to the arc that occurs when relay contacts open and close, and adheres to the contacts as carbon, increasing contact resistance. However, there was a problem in that the contacts would wear out more quickly. Furthermore, when applying the lubricant, it was difficult to apply the lubricant uniformly to the surface of the electric wire, and stable surface lubricity could not be obtained. Furthermore, although the abrasion resistance of the coating can be improved by coating the outer periphery of the insulating coating with nylon, there is a problem in that the heat resistance and moisture resistance are reduced due to the characteristics of the nylon resin.

とが問題になっていた。Additionally, when using additive lubricants such as higher fatty acid esters added to insulation paints, the boiling point of the lubricant higher fatty acid esters is close to that of cresol, which is the solvent for insulation paints. In some cases, the lubricant evaporates, and in some cases, it hardly remains in the film, so it tends to lose its lubricating effect.Furthermore, due to the difference in chemical structure of the lubricant, it has poor compatibility or dispersibility with the paint, so the amount added is limited. There was a problem with putting it away. In order to solve these problems, a lubricating nylon paint made by adding a lubricant to nylon and dissolving it in an organic solvent was applied to the outer periphery of the insulating film and baked.
Wear resistance of insulated wires 1. Methods have been taken to improve surface lubricity. However, there has been a problem in that the heat resistance of the insulating film decreases, significantly impairing the reliability of the insulated wire.

This polyether sulfone resin is a thermoplastic polymer obtained by the polycondensation reaction of DCDPS) and has the following general formula.This polyether sulfone resin has excellent heat resistance, 9 mechanical properties, electrical properties, chemical resistance, and water resistance. Generally, in the case of crystalline resins such as 6-nylon and 6-6 nylon, physical property values tend to change rapidly as the temperature rises. On the other hand, polyethersulfone resin is a non-crystalline resin with no localized electrons in the diphenylsulfone part due to its molecular structure, so its physical properties change very little with temperature increases and are strong over a wide temperature range. It has high strength and strength. It also has the great advantage of exhibiting excellent resistance to acids, alkalis, gasoline, etc., as well as excellent hot water resistance and steam resistance. A specific example of this polyether sulfone resin is as follows.

コーンは次の一般式で示される。The silicone-modified epoxy resin used as the second component of the lubricious insulating paint is a reactive silicone having a molecular weight of 1,000 to 10,000 (hereinafter referred to as 1) having an amino group at the end.
(abbreviated as reactive silicone) and epoxy equivalent of 450~
It is obtained by reacting 4,000% bisphenol A type epoxy resin (hereinafter abbreviated as epoxy resin), and by adding it to the main component polyethersulfone resin, it provides lubricity to the surface of insulated wires. It is used for the purpose of improving winding properties. This silicone-modified epoxy resin also has excellent water resistance. The reactive silicone is used as a component that imparts lubricity,
If added directly to polyether sulfone resin and dispersed or dissolved in an organic solvent, the paint will be unstable and will separate if left for a long time.Additionally, reactive silicone has amino groups, but polyether Since sulfone resins do not have reactive groups, chemical reactions sometimes do not occur during baking of paints, and most of the reactive silicone evaporates, making it impossible to obtain good surface lubricity. Therefore, a zero-reactive silicone that uses a silicone-modified epoxy resin obtained by reacting a reactive silicone and an epoxy resin in advance as a lubricity imparting component is represented by the following general formula.

The reason for this limitation is that if the molecular weight is less than 1,000, it will have little effect as a lubricity-imparting component;

得られないためである。The epoxy resin is used to react with the reactive silicone to improve the stability of the paint and to improve the thermal stability of the lubricant during baking. Specific examples include Epicoat 1001, Epicoat 1004, and Epicoat 1007.
．． 1009 (product name of Yuka Shell Epoxy Co., Ltd.), Epotote VD-011. VD-014, 1-017 (
Tobu Kasei Co., Ltd. (trade name), etc. The reason for limiting the epoxy equivalent of the epoxy resin to 450 to 4,000 is that if the epoxy equivalent is less than 450, the epoxy resin is highly reactive, making it difficult to control the reaction with reactive silicone. This is because if the amount exceeds 100%, the content of silicone in the reactant decreases and good surface lubricity cannot be obtained.

合は良好な表面潤滑性が得られず。The reason why the amount of the silicone-modified epoxy resin added is limited to 0.1 to 20 parts by weight per 100 parts by weight of the polyethersulfone resin is that when the amount added is less than 0.1 part by weight, good surface lubrication is achieved. I can't get sex.

A lubricating insulating paint made by dispersing and dissolving 1171 and a silicone-modified epoxy resin in an organic solvent can be obtained by applying and baking a lubricious insulating paint onto a conductor directly or via an insulating film. Therefore, the insulated wire has excellent heat resistance and water resistance due to the polyether sulfone resin, and exhibits excellent surface lubricity due to the silicone-modified epoxy resin.

Even after baking, it is uniformly dispersed in the main component polyethersulfone resin, so it is possible to impart uniform and stable lubricity to the surface of the film. Furthermore, since the water resistance of the silicone-modified epoxy resin is added to the polyether sulfone resin, it is possible to form an insulating film that can withstand use under high temperature and high humidity conditions.

いる中で。The lubricious insulated wire of the present invention has a coating with a surface friction coefficient μ of 0.1θ to 0.11, which is extremely excellent in surface lubricity, as shown in the examples in Table 1, so that it can be used for coil winding. Linearity is extremely good. That is, when winding a coil, the wire is easily drawn out from the bobbin, so there is no wire breakage, and since the wire can be wound with stable tension, there is little processing deterioration of the wire, and it can be used for high-speed winding. Additionally, liquid paraffin generates organic gases that cause electrical and electronic equipment to malfunction.
Since no refrigerating machine oil or the like is applied to the surface of the film, the reliability of electrical and electronic equipment is significantly improved. In addition, as shown in the examples in Table 2, it has extremely excellent heat resistance and heat and humidity resistance, so it can sufficiently withstand use under high temperature and high humidity conditions. Therefore, the lubricious insulated wire of the present invention can be used in increasingly harsh environments due to the miniaturization and higher performance of electrical and electronic equipment.
その用途に適した信頼性の高い絶縁電線として有用であ
る。It is useful as a highly reliable insulated wire suitable for that purpose.
