【発明の詳細な説明】
（産業上の利用分野）
この発明は、ノンハロゲン難燃熱収縮材料に係るもので
ある。DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a non-halogen flame-retardant heat-shrinkable material.
（従来の技術）
エチレンプロピレンターポリマー（以下単にＥＦＴと呼
称する）に塩素系あるいは臭素系の難燃剤を混和したも
のが従来難燃材料として公知であった。(Prior Art) Ethylene propylene terpolymer (hereinafter simply referred to as EFT) mixed with a chlorine-based or bromine-based flame retardant has been known as a flame retardant material.
しかし、この難燃材料は燃焼時に有害なハロゲンガスを
発里し、人体に悪影響を及ぼすという重大な問題点を有
していた。また、形状に対するメモリー性を有していな
いので、熱収縮材料としては使用できないという問題点
も有していた。However, this flame-retardant material has the serious problem of emitting harmful halogen gas when burned, which has an adverse effect on the human body. Another problem is that it cannot be used as a heat-shrinkable material because it does not have shape memory.
（発明が解決しようとする問題点）
この発明は従来技術が有していた前記の問題点を解消す
るために成されたものである。(Problems to be Solved by the Invention) The present invention has been made in order to solve the above-mentioned problems that the prior art had.
（問題点を解決するための手段）
燃焼時にハロゲンガスを発生しない難燃材と形状メモリ
ー１１１能を有するメモリー材をＥＰＴに混和するので
ある。(Means for solving the problem) A flame retardant material that does not generate halogen gas during combustion and a memory material that has shape memory 111 ability are mixed into EPT.
（作ｆｆ１）
この難燃材がハロゲンガスの発生を皆無にし、メモリー
材が熱収縮特性を付与するように作用するのである。(Production ff1) This flame retardant material completely eliminates the generation of halogen gas, and the memory material acts to impart heat shrinkage properties.
（実施例）
ＥＰＴ１００Ｗ量部に対し、メモリー材としてポリオレ

和してＥＰＴの組成分、すなわち、ノンハロゲン難燃熱
収縮材料を構成させるのである。(Example) For 100 W parts of EPT, 5 to 100 parts by weight of polyolefin such as LDPE as a memory material, 50 to 150 parts by weight of powder mainly composed of magnesium hydroxide and 2 to 100 parts of red phosphorus as a flame retardant. The components of EPT, that is, the halogen-free flame-retardant heat-shrinkable material are formed by mixing these parts together.
実施に際しては、この材料を例えばチューブなど、榎々

晶の融点以上の加熱下で、所定の形状に膨張させ、その
ままの状態で常温にまで冷却きせるのである。このよう
にして、ノンハロゲン難燃熱収縮成形品を得るのである
。When carrying out the process, this material is molded into a shape such as a tube, cross-linked, and then expanded into the desired shape under heating above the melting point of polyolefin crystals, and then cooled as it is to room temperature. It can be done. In this way, a halogen-free flame-retardant heat-shrinkable molded product is obtained.
この発明においては、ポリオレフィンが５重量部未満で

とする粉体が５０重量部、赤リンが２重量部未満では難
燃性が殆んどなくなり、水酸化マグネシウムを主体とす
る粉体が１５０！重量部を超えると硬くなり加工性が著
しく悪くなるので実用性がなくなる。赤リンが１０重量
部を超えると、難燃性の向上は微小で、殆んど期待でき
ないのに対し、コストが著しく高くなり工業的実朋注は
殆んど消失する。In this invention, if the polyolefin is less than 5 parts by weight, memory properties will be lost, and if it exceeds 100 parts by weight, it will become hard and impractical. Moreover, if the powder mainly consists of magnesium hydroxide is 50 parts by weight and the red phosphorus content is less than 2 parts by weight, the flame retardance will almost disappear; If it exceeds the weight part, it will become hard and workability will deteriorate significantly, making it impractical. When the amount of red phosphorus exceeds 10 parts by weight, the improvement in flame retardancy is so small that it can hardly be expected, while the cost becomes extremely high and there is almost no industrial practical application.
（効果）
この発明は以上のように構成されているので、次のよう
な効果を有している。(Effects) Since the present invention is configured as described above, it has the following effects.
（１）燃焼時にハロゲンガスが発生しない。(1) Halogen gas is not generated during combustion.
（２）熱収縮性を有している。(2) It has heat shrinkability.
従って、常時人が居住し、火災時に人命にかかわるおそ
れのあるビル、マンション等の建築物の電気設備の絶縁
保護材やケーブル端末処理材料などに広く使用できる。Therefore, it can be widely used as an insulating protection material for electrical equipment in buildings such as buildings and condominiums where people live all the time and where there is a danger of human life in the event of a fire, or as a cable terminal treatment material.
