【発明の詳細な説明】
（産業上の利用分野）
本発明は自己融着性絶縁電線に関し、・さらに詳しくは
、耐熱性、耐溶剤性、耐冷媒性に優れた自己融着性絶縁
電線に関するものである。Detailed Description of the Invention (Industrial Application Field) The present invention relates to a self-bonding insulated wire, and more particularly, to a self-bonding insulated wire with excellent heat resistance, solvent resistance, and refrigerant resistance. It is something.
（従来の技術）
自己融着性絶縁電線は、コイル巻工程の後加熱または溶
剤に浸漬するのみでコイル巻き線間の固着が可能なため
、広く使用されている。しかしその利用分野は小型モー
ター、小型トランス、等の低温で使用される静止機器の
みに使用されているのが実情であった。(Prior Art) Self-bonding insulated wires are widely used because coil windings can be fixed together simply by heating or dipping in a solvent after the coil winding process. However, the reality is that they are used only in stationary equipment used at low temperatures, such as small motors and small transformers.
自己融着性絶縁電線の使用が最も要望されている分野は
、上記に止まらず、汎用モータ、コンプレッサモータ等
、数多い。しかし従来の自己融着性絶縁電線の使用用途
が上記の分野に限定されている理由は、まずその耐熱性
にある。はとんどの自己融着性絶縁電線の融着層は熱可
塑性樹脂を使用しており、従って融着に要する温度の制
限があり、その使用温度はせいぜい１００℃どまりであ
った。また近年この欠点を克服すべく種々の提案がなさ
れている。たとえば、エポキシ、ポリエステル等の熱可
塑性樹脂に硬化剤を配合し、この塗料の塗膜をＢステー
ジに焼き付けることにより、高温域での接着力を向上さ
せる等の試みである。The fields in which the use of self-bonding insulated wires is most desired are not limited to those mentioned above, but include general-purpose motors, compressor motors, and many other applications. However, the reason why conventional self-bonding insulated wires are used only in the above-mentioned fields is primarily their heat resistance. The fusing layer of most self-fusing insulated wires uses thermoplastic resin, and therefore there is a limit to the temperature required for fusing, and the operating temperature is no more than 100°C. In recent years, various proposals have been made to overcome this drawback. For example, attempts have been made to improve adhesive strength in high temperature ranges by blending a hardening agent into thermoplastic resins such as epoxy and polyester and baking the paint film to the B stage.
しかし、これら従来の発明では、絶縁電線としての可撓
性、シェルフライフが低下することは避けられず、また
基本的に硬化のみで高温域の特性を得ているもので本質
的に高１１耐熱性を有しているわけではない。したがっ
てこの種の自己融着性絶縁電線はその使用に関してかな
りの制限があった。However, with these conventional inventions, it is unavoidable that the flexibility and shelf life of the insulated wire are reduced, and the characteristics in the high temperature range are basically obtained only by hardening, which essentially means high heat resistance. It does not have a gender. Therefore, there are considerable limitations regarding the use of this type of self-bonding insulated wire.

本発明者等は上記の事情に鑑み、本質的に耐熱性に優れ

The present invention was achieved as a result of extensive research.

The self-bonding insulated wire is characterized in that it is made by coating and baking a paint containing 5 to 50 parts by weight (c) dissolved in an organic solvent.
本発明はポリエーテルイミド樹脂と線状ポリエステル樹
脂と架橋剤の３成分を主として構成された自己融着層を
有する自己融着性絶縁電線であるが第一の構成成分であ
るポリエーテルイミド樹脂とは下記の構造式を有するも
のであり、具体的には、米国ＧＥ社製商品名ウつテムが
ある。The present invention is a self-bonding insulated wire having a self-bonding layer mainly composed of three components: a polyetherimide resin, a linear polyester resin, and a crosslinking agent. has the following structural formula, and specifically, there is a product name Utsutem manufactured by GE Corporation in the United States.
また、第二の構成成分である線状ポリエステル樹脂とは
、脂肪族・芳香族ジカルボン酸と２価のアルコールより
得られる線状のポリエステル樹脂で、具体的な商品名と
しては、東洋紡績社製商品名バイロン２００および同社
製バイロン３００等があげられる。The second component, linear polyester resin, is a linear polyester resin obtained from aliphatic/aromatic dicarboxylic acid and dihydric alcohol. Examples include the product name Byron 200 and the company's Byron 300.

ゾール、レゾール及びノボラック型を含む。Next, among the group of crosslinking agents as the third component used in the present invention, phenol formaldehyde resin broadly refers to a condensate of phenols and formaldehyde, and includes phenol, cresol, resol, and novolak types.
また、メラミンホルムアルデヒド樹脂とは、メラミンと
ホルムアルデヒドとの縮合物であるが、アルキル化され

有機チタン化合物とは、テトラアルキルチタネート等の
チタン酸エステル及びチタンキレート化合物を含むもの
である。The organic titanium compound includes titanate esters such as tetraalkyl titanates and titanium chelate compounds.
本発明で自己融着層を形成する塗料の組成において各々
の配合量をポリエーテルイミド樹脂１００重量部に対し
て、線状ポリエステル樹脂を２０〜２００重量部と限定
した理由は、線状ポリエステル樹脂が２０重量部未満で
あると得られる被膜は接告に要する温度が高すぎて実用
的でないためであり、また２００重量部を超えての配合
では得られる被膜が高温域での接着力等、高温特性が劣
るためである。The reason why the amount of linear polyester resin is limited to 20 to 200 parts by weight per 100 parts by weight of polyetherimide resin in the composition of the paint forming the self-adhesive layer in the present invention is that If the amount is less than 20 parts by weight, the resulting film will require too high a temperature for adhesion to be practical, and if it exceeds 200 parts by weight, the resulting film will have poor adhesion at high temperatures, etc. This is because the high-temperature properties are inferior.

合物のうち１種または２種以上の混合物などの架橋剤の
配合割合をポリエーテルイミド樹脂１００重量部に対し
て５〜５０重量部と限定した理由は、５重量部未満であ
ると得られる被膜は架橋の効果に乏しく、耐熱性が低下
し、また５０重量部を超えての配合では、得られた自己
融着性絶縁電線の可撓性が低下するためである。Furthermore, the blending ratio of a crosslinking agent such as one or a mixture of two or more of phenol formaldehyde resin, melamine formaldehyde resin, stabilized incyaneto, and organic titanium compounds is 5 to 50 parts by weight per 100 parts by weight of polyetherimide resin. The reason for this limitation is that if the amount is less than 5 parts by weight, the resulting coating will have poor crosslinking effect and the heat resistance will be reduced, and if it is more than 50 parts by weight, the resulting self-bonding insulated wire will be difficult to form. This is because flexibility decreases.
