コイル巻線に広く用いられている。For self-fusing insulated wires, an insulating coating mainly composed of polyurethane, polyester, or polyesterimide resin is applied to the conductor and baked to form an insulating film, and furthermore, a polyvinyl butyral, polyamide or epoxy resin, etc. is provided on the outer periphery. Applying and baking a thermoplastic resin paint as a component to provide a fused film. After winding the coil, the fused film is dissolved or swelled by heating or solvent treatment, and the wires can be firmly connected to each other. , A deflection yoke, an air-core coil, a voice coil, and various other coil windings.

問題があった。The fusion coating of such self-fusing insulated wires is a thermoplastic coating, and the mechanical strength of the coating, especially the wear resistance, is inferior to other thermosetting insulation coatings. There is a problem that the film cannot be tolerated by the mechanical stress of the time, and in an extreme case, the film is damaged and rare short occurs.

膜の表面に塗布したものが用いられていた。In order to solve these problems, it is necessary to apply a lubricant to the fusion coating to reduce the mechanical stress and scratches applied to the coating. For this reason, conventionally, liquid lubricants such as liquid paraffin or refrigeration oil, Alternatively, a solid lubricant such as solid paraffin or wax is dissolved by heating or a lubricant obtained by dissolving the lubricant in a solvent is applied to the surface of the fusion coating.

で線間接着力が低下してしまうという問題点があった。However, in the case of a self-fusing insulated wire in which a liquid lubricant is applied to the surface of the fusion coating, it is difficult to apply the liquid lubricant uniformly to the coating surface at the time of manufacturing. Lubricity is difficult to secure and lubrication properties are not particularly excellent. In recent high-speed, high-load windings, coil dimensional defects and rare short circuits cannot be sufficiently prevented. There was a point. In addition, in the case of self-fusing insulated wires in which a solid lubricant is applied to the surface of the fusion coating, the lubrication characteristics are better than those using a liquid lubricant. Or apply it to the surface of the fusion coating, or dissolve a solid lubricant in an organic solvent, apply it to the surface of the fusion coating and dry it. Heating and melting of the agent, a coating device, and a coating and drying device are required, resulting in an increase in cost. Also. It was very difficult to apply a uniform coating thickness in the longitudinal direction of the electric wire. Also, if the film thickness of the applied solid lubricant is too thick, it will be scraped off by the capstan or pulley, and the shavings will adhere to the drive pulley and become dirty. There was a problem that would. Further, when the wound coil is washed with a Freon solvent, there is a problem that the surface is whitened and the appearance of the coil is deteriorated. Further, the self-fusing insulated wire in which a liquid lubricant or a solid lubricant is applied to the surface of the fusion coating has a problem that the adhesive force between the wires is reduced by the action of the lubricant.

好ましい。しかしながら特に限定されるものではない。Examples of the thermoplastic resin having a reactive group according to the present invention include 12-nylon-based copolymer polyamide resin or bisphenol A-based epoxy resin, and these resins are considered in consideration of compatibility with the resin as a main component of the fusion coating material. Used as Therefore, when the main resin of the fusion coating is a polyamide resin,
It is preferable to use a 12-nylon copolymer polyamide resin, and it is preferable to use a bisphenol A-based epoxy resin when the resin as the main component of the fusion coating is an epoxy-based resin. However, it is not particularly limited.

である。The reason for limiting the addition of the terminal epoxy group higher fatty acid-derived substance to 20 nylon-based copolymer polyamide resin and bisphenol A-based epoxy resin by 20 to 100% of the reaction equivalent of the resin is that the addition amount is less than 20%. In the case of (1), no lubricating effect can be expected, and when it exceeds 100%, unreacted lubricant is present, and a stable lubricating effect cannot be obtained.

めないうえにコイルの接着力を低下させる。Also, the reason why the amount of the reaction product added is limited to 1 to 100% by weight based on the resin content of the fusion coating is that if it is less than 1% by weight, it is difficult to impart sufficient lubricity to the fusion coating. On the other hand, if it exceeds 100% by weight, no improvement in lubricity can be expected and the adhesive strength of the coil is reduced.

持される。The reaction product of the present invention is obtained by adding 20 to 100% of a terminal epoxy group higher fatty acid-derived substance to a reaction equivalent of 12 nylon-based copolymer polyamide resin and bisphenol A-based epoxy resin.
The reaction product is added and reacted in an organic solvent to completely block the reactive group, so that a stable form of lubricating reaction product is obtained. A fusion coating obtained by adding 1 to 100% by weight of the reaction product to the resin component of the fusion coating also becomes a stable fusion coating. At this time, the thermoplastic resin having a reactive group is 12 nylon-based copolymer polyamide resin or bisphenol A-based epoxy resin, and the most stable form when these resins and the resin as the main component of the fusion coating are compatible. Fusing paint. Accordingly, the reaction product is uniformly dispersed on the surface of the fusion coating obtained by applying and baking this fusion coating via an insulating film on the conductor, and good lubricating properties are uniformly imparted in the longitudinal direction of the electric wire and the wire is coated. The inter-bonding strength is also maintained.

る。 [Effects of the Invention] The fusing paint used in the present invention is obtained by fusing a reaction product obtained by sufficiently reacting a terminal fatty acid-derived higher fatty acid-derived substance with a 12-nylon copolymerized polyamide resin and a bisphenol A-based epoxy resin in advance. It may be simply added to the paint. Therefore, the amount of the reaction product added in the fusing paint is small, so that the fusing paint has a stable form. Therefore, the self-lubricating fusible insulated wire of the present invention, in which the fusible coating is applied through an insulating film and baked, has a liquid lubricating property on the surface of the conventional fusible film, as is clear from the characteristic results in Table 1. As compared with a self-fusing insulated wire coated with an agent or a solid lubricant, surface lubricity and adhesion can be improved without impairing other characteristics at all. In addition, there is no need to separately provide a lubricant application device or the like, which has been a factor in increasing the cost when using a solid lubricant, and there is no risk of soiling the pulleys. Therefore, the effect of contributing to the industry is extremely large.
