絶縁電線に関するものである。[Detailed Description of the Invention] [Industrial Application Field] The present invention makes it possible to apply an extremely thin coating, which allows the layer to be made smaller in diameter, and has sufficient mechanical strength and abrasion resistance. The present invention also relates to a new thin-walled insulated wire having the necessary electrical insulation performance.
［従来の技術］

続する電線に対しても、絶縁体の薄肉化そして電線自体
の細径化への要望が高まってきている。[Prior Art] In recent years, communication equipment and precision electronic equipment have shown a remarkable trend toward miniaturization and high-density packaging.Furthermore, many small precision equipment with such various functions are being installed in automobiles and other vehicles. In order to make effective use of limited space, not only the internal wiring of devices, but also the wires that connect these devices are being made with thinner insulators and smaller diameter wires. The demand for this is increasing.

た。[Problems to be Solved by the Invention] Even if the thickness of the conventional resin composition mainly made of polyvinyl chloride as described above can be made thin, the limit is about 350 μm, and the machine There was a problem in that the mechanical strength, especially the abrasion characteristics, decreased significantly, and this created a barrier to thinner walls and smaller diameters.
ポリアミドは機械的強度が大きく耐摩耗性に優れた材料

く限られた場合を除き、電線への絶縁被覆材料として用
いられることはなかった。Polyamide is a material with high mechanical strength and excellent wear resistance. This polyamide is used as a sheath material for some electric wires, but when viewed as an insulating material for electric wires, it has the disadvantage of low insulation resistance when moisture is absorbed, so it is not used except in very limited cases. It has never been used as an insulation coating material for electric wires.
本発明の目的は、ポリアミドの有する上記した優れた耐
摩耗性に着目し、従来欠点とされてきた低い体積抵抗率
を大巾に改善することにより絶縁被覆材料として使用す

極めて薄肉の絶縁層を有する細径絶縁電線を提供しよう
とするものである。The purpose of the present invention is to focus on the above-mentioned excellent wear resistance of polyamide, and to make it possible to use it as an insulating coating material by significantly improving the low volume resistivity, which has been considered a drawback in the past. Thereby, the present invention aims to provide a small-diameter insulated wire having an extremely thin insulating layer with excellent wear resistance.
［課題を解決するための手段］
本発明は、導体の外周にポリアミド７０〜３０重量部に
対しポリフェニレンオキサイドを３０〜７０重量部混合

射線で架橋したものである。[Means for Solving the Problems] The present invention provides an insulator with an extruded coating layer mainly composed of a resin composition obtained by mixing 30 to 70 parts by weight of polyphenylene oxide to 70 to 30 parts by weight of polyamide on the outer periphery of a conductor. The coating layer is further crosslinked with ionizing radiation.
ポリアミドは、前述した通り単独の材料としては体積抵
抗率が低く、絶縁材料として使用することはできない。As described above, polyamide has a low volume resistivity as a single material and cannot be used as an insulating material.
しかし耐摩耗性においては優れた材料であり、電線の絶
縁体を薄肉化する上において決め手ともいえる性質を有
している。However, it is a material with excellent wear resistance, and has properties that can be said to be a decisive factor in making the insulation of electric wires thinner.
このため、発明者らは、ポリアミドの有する優れた耐摩
耗性を損うことなく絶縁体として体積抵抗率を向上させ
得るようなポリマをブレンドすることを試み、広範囲に
わたり種々な検討を行なった。この結果、ポリアミドに
ブレンドしたほとんどのプラチックスはその耐摩耗性を

摩耗性を損うことなく体積抵抗率を向上させることがで
き、このブレンド組成物を絶縁体層として押出被覆する
ことで所望の特性を充足する薄肉絶縁電線を入手し得る
ことを見出し、本発明に至ったものである。For this reason, the inventors attempted to blend a polymer that could improve the volume resistivity as an insulator without impairing the excellent wear resistance of polyamide, and conducted various studies over a wide range. As a result, most plastics blended with polyamides reduced their abrasion resistance, but only polyphenylene oxide was able to increase volume resistivity without compromising abrasion resistance, making this blend composition an insulating material. The inventors have discovered that it is possible to obtain a thin insulated wire that satisfies the desired properties by extrusion coating it as a body layer, leading to the present invention.
本発明におけるポリアミドとしては、ナイロン６６、ナ
イロン６、ナイロン６１０、ナイロン１１、ナイロン１

独使用ばかりでなく２種以上をブレンドして使用するこ
ともできる。Examples of the polyamide in the present invention include nylon 66, nylon 6, nylon 610, nylon 11, and nylon 1.
2, nylon 46, etc. These can be used not only alone but also as a blend of two or more.
また、本発明にいうポリフェニレンオキサイドとは、次
の一般式で示されるポリマである。Moreover, the polyphenylene oxide referred to in the present invention is a polymer represented by the following general formula.
上記のポリアミドとポリフェニレンオキサイドの混合割
合はポリアミド７０〜３０重量部に対しポリフェニレン
オキサイド３０〜７０重量部である。ポリアミドが７０
部を越えると絶縁抵抗の低下が大きく、３０重量部未満
では混合物の伸びが低下するため好ましくない。The mixing ratio of the polyamide and polyphenylene oxide is 70 to 30 parts by weight of the polyamide and 30 to 70 parts by weight of the polyphenylene oxide. Polyamide is 70
If it exceeds 30 parts by weight, the insulation resistance will be greatly reduced, and if it is less than 30 parts by weight, the elongation of the mixture will decrease, which is not preferable.

れによりさらに耐摩耗性を向上させることができる。Further, the resin composition according to the present invention can be crosslinked by blending a polyfunctional monomer such as triallyl isocyanurate, triallyl cyanurate, diallyl phthalate, etc. and irradiating it with ionizing radiation such as an electron beam. This can further improve wear resistance.
なお、本発明の樹脂組成物には適宜着色剤、酸化防止剤
、軟化剤、可塑剤等の添加剤を加えることができる。In addition, additives such as colorants, antioxidants, softeners, plasticizers, etc. can be added to the resin composition of the present invention as appropriate.

悪影響を及ぼさない範囲で加えることも可能である。In addition to polyamide and polyphenylene oxide, so-called compatibilizing agents such as acid-modified polystyrene and styrene-ethylene/butylene-styrene block copolymers are used to improve the compatibility of these polymers, which have an adverse effect on wear resistance. It is also possible to add as much as possible.
