る。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a halogen-free flame-retardant insulated wire having excellent wire stripping properties.
【０００２】[0002]
【従来の技術】一般に、家電品やＯＡ機器の口出線とし
て用いられている絶縁電線は導線上に電気絶縁材料を押
し出し被覆して成るものである。2. Description of the Related Art Generally, an insulated wire used as a lead wire of home appliances and OA equipment is formed by extruding and covering an electrically insulating material on a conductive wire.
【０００３】従来、これら家電品やＯＡ機器の口出線の
電気絶縁被覆材料としては塩化ビニル樹脂混和物が最も
多く用いられてきた。この理由は塩化ビニル樹脂混和物
が安価で、且つ優れた難燃性を有しており、しかも優れ
た可撓性、着色性、電気的特性等も有しているためと考
えられている。Heretofore, a vinyl chloride resin admixture has been most often used as an electrically insulating coating material for lead wires of these home appliances and OA equipment. It is considered that the reason for this is that the vinyl chloride resin admixture is inexpensive, has excellent flame retardancy, and also has excellent flexibility, coloring properties, electrical properties and the like.
【０００４】しかし塩化ビニル樹脂混和物はそのベース
ポリマである塩化ビニル樹脂分子骨格内に大量の塩素を

るという難点がある。また、この塩化ビニル樹脂混和物
はそのベースポリマである塩化ビニル樹脂の分子骨格内
に大量の塩素を含むため埋め立て廃棄処分するとダイオ
キシンの発生要因の一つとなる。However, since the vinyl chloride resin admixture contains a large amount of chlorine in the vinyl chloride resin molecular skeleton as its base polymer, it is toxic and corrosive when burned or subjected to high heat, such as hydrogen chloride gas or chlorine gas. There is a drawback that large amounts of gas and smoke are generated. In addition, since this vinyl chloride resin mixture contains a large amount of chlorine in the molecular skeleton of the vinyl chloride resin as a base polymer, it becomes one of the factors of dioxin generation when it is landfilled and disposed of.
【０００５】更に、塩化ビニル樹脂混和物には鉛等の重
金属化合物、可塑剤等が配合されているため、その塩化
ビニル樹脂混和物を導線上に押し出し被覆して成る塩化
ビニル樹脂混和物絶縁電線を埋め立て処分したときには
土壌、地下水等を重金属化合物、可塑剤等で汚染する懸
念がある。Further, since the polyvinyl chloride resin mixture contains a heavy metal compound such as lead, a plasticizer, and the like, the vinyl chloride resin mixture is extruded onto a conductive wire to cover the insulated wire. There is a concern that soil and groundwater will be contaminated with heavy metal compounds, plasticizers, etc. when landfilled.
【０００６】このような背景から近年では燃焼時に有害
ガスを発生することがなく、且つ有害重金属を含まない
環境配慮型絶縁電線が要求されるようになってきてい
る。[0006] From such a background, in recent years, environmentally friendly insulated wires that do not generate harmful gas during combustion and do not contain harmful heavy metals have been required.
【０００７】[0007]
【発明が解決しようとする課題】従来、燃焼時に有害ガ

重金属を含まない充填剤を配合することが行われてい
る。Conventionally, a base polymer containing no halogen element has been used as an electric insulating material of an environmentally conscious insulated wire which does not generate harmful gas during combustion and does not contain harmful heavy metals. It has been practiced to incorporate a filler containing no halogen element or harmful heavy metal into the base polymer containing no halogen element.

Vinyl acetate copolymers and ethylene / ethyl acrylate polymers have been used.
【０００９】他方、ハロゲン元素や有害重金属を含まな
い充填剤としては金属水酸化物等が用いられてきた。On the other hand, metal hydroxides and the like have been used as fillers which do not contain halogen elements or harmful heavy metals.

性によりノンハロゲン難燃絶縁材料と導線との粘着性が
強くなることが知られている。However, these ethylene / vinyl acetate copolymers and ethylene / ethyl acrylate polymers have a polar group in the molecular skeleton, and therefore have a large polarity. Therefore, a halogen-free flame-retardant insulating material obtained by mixing a metal hydroxide with these polar polymers also has a large polarity. For this reason, it has been known that, in a non-halogen insulated wire formed by extruding and coating this non-halogen flame-retardant insulating material onto a conductive wire, the adhesiveness between the non-halogen flame-retardant insulating material and the conductive wire becomes stronger due to the polarity of the extruded and coated polar polymer. I have.

工性、つまりワイヤストリップ性が著しく劣るという難
点がある。The strong adhesion between the non-halogen flame-retardant insulated material and the conductive wire is favorable for the electrical properties, mechanical properties, chemical properties and the like of the non-halogen flame-retardant insulated wire. This is inconvenient when stripping off the non-halogen flame-retardant insulating layer at the end of the flame-retardant insulated wire from the conductor. In other words, non-halogen insulated wires made by extruding and coating non-halogen flame-retardant insulating material, which is a mixture of ethylene-vinyl acetate copolymer or ethylene-ethyl acrylate polymer with a metal hydroxide, on the conductor, are end workable, that is, wire strip. There is a disadvantage that the properties are extremely poor.
