産業上の利用分野
本発明は、紫外線硬化性と自己融着性とを併せ有する樹

ある。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a method for manufacturing a coil using a resin composition that has both ultraviolet curability and self-fusion properties.

。[Prior art] A typical method for producing coils is to wind an electric wire coated with a self-bonding insulating paint into a coil, and then heat the coil (or by dipping it in a solvent and then heating it). , a method of fusing electric wires together is known.
従来、この目的の絶縁塗料としては、ポリビニルブチラ

発明が解決しようとする問題点
しかしながら、コイルを製造すべく導体に自己融着性を
有する絶縁塗料を焼き付ける際には、一般に厚塗りがで
きないため、塗ＩＨｊ−焼き付けの操作を多数回行わな
ければならないという不利があった・
また焼き伺は条件によっては所期の融着性が得られない
こともあった。たとえば熱硬化性樹脂を用いるときには
、乾燥条件に細心の注意を払わないと未硬化の部分が生
じたり、あるいは過硬化となって、次の融着工程に支障
を来たすおそれがあった。Conventionally, various thermoplastic resins and thermosetting resins such as polyvinyl butyral, alcohol-soluble polyamide, epoxy resin, and unsaturated polyester have been used as insulating coatings for this purpose. (For example, Tokuko Sho 39-286
Publication No. 00, Special Publication No. 39-28601, Special Publication No. 4

9 o'clock bulletin, etc.) Problems to be Solved by the Invention However, when baking an insulating paint that has self-bonding properties onto a conductor to manufacture a coil, it is generally not possible to apply thickly, so the coating IHj-baking operation is difficult. This had the disadvantage of having to be repeated multiple times.Additionally, depending on the conditions, it may not be possible to obtain the desired fusion properties. For example, when using a thermosetting resin, if careful attention is not paid to drying conditions, there is a risk that uncured portions may occur or overcuring may occur, interfering with the next fusion process.
そのため従来の方法は、工程管理、労働工数、生産性、
熱エネルギーの消費などの点で種々の不利があり、その

らに加熱を続行すれば最終硬化が図られる。The heating temperature should be at least the melting temperature of the thermoplastic resin if it is blended with a thermoplastic resin, or above the melting temperature of the thermoplastic resin if it is blended with a thermosetting resin or if the ultraviolet curable resin itself has thermosetting properties. The temperature is set so that the thermosetting resin melts and then hardens. In the former case, final hardening is achieved by cooling after the completion of fusion, and in the latter case, final hardening is achieved by continuing heating after completion of fusion.
