【発明の属する技術分野】本発明は、絶縁電線、特に車
両などで用いられる低電圧ワイヤーハーネス用の絶縁電

としてポリ塩化ビニル（ＰＶＣ）を使用している。2. Description of the Related Art Conventionally, polyvinyl chloride (PVC) is generally used as an insulator in an insulated wire (cable) for a low-voltage wire harness such as a vehicle.

どにも耐えることができる耐磨耗性も高いという利点が
ある反面、燃焼した際、ハロゲン元素を含有することか
ら、有毒なガスを出すなどの問題があった。[0005] In addition to being advantageous in terms of cost, PVC has the advantages that it has excellent flame retardancy and also has high abrasion resistance that can withstand wiring inside the vehicle. However, when it burns, it contains a halogen element, so that there is a problem that toxic gas is emitted.

題の高まりと相まって早急な解決が望まれていた。[0004] This toxic gas is used, for example, when a vehicle is treated after a fire in a tunnel or the like, when the entire vehicle is pressed and incinerated as a scrapped car, and a large number of wire harnesses taken out of the scrapped car are industrially used. When incinerated as waste or the like, it presents a serious problem, and in response to the growing environmental problems in recent years, an immediate solution has been desired.

いることも考えられるが、ＰＥの場合、ハロゲン元素を
含有しないため、有毒ガスの発生はないものの、耐磨耗
性が劣り、また、難燃性も低いなどの問題があった。For this reason, it is conceivable to use polyethylene (PE), which is often used, as an insulating resin for electric wires as an alternative resin. However, PE does not generate a toxic gas because it does not contain a halogen element. However, there are problems such as poor abrasion resistance and low flame retardancy.

It is an object of the present invention to provide an insulated wire made of an insulator in which a whitening phenomenon in which a portion becomes white is suppressed favorably.

It is possible to set a larger amount of the metal hydroxide compound to be added. The preferred characteristics of EVA or EEA are, for example, that VA% or EA% is about 10 to 50 and Meltodex (MI) is about 0.5 to 10 g /

In the case of blending with the P block copolymer, the total blending amount of both is 100 parts by weight, and the PP block copolymer is 80 to 20 parts by weight with respect to 20 to 80 parts by weight of EEA. That is, if EVA or EEA is less than 20 parts by weight,
When the PP block copolymer exceeds 80 parts by weight, the abrasion resistance is improved, but the addition of a metal hydroxide compound as a flame retardant cannot be expected, and conversely, EVA or EEA becomes 80 parts by weight. If the PP block copolymer is less than 20 parts by weight, the desired abrasion resistance cannot be obtained.
【００１１】本発明で用いる難燃剤としての水酸化金属

め、大きな難燃性を呈するものである。Examples of the metal hydroxide compound as the flame retardant used in the present invention include magnesium hydroxide (Mg) and aluminum hydroxide (Al). These compounds exhibit high flame retardancy when exposed to a high temperature in a fire or the like, since the contained water of crystallization is decomposed to remove surrounding heat.

００重量部としたのは、これを越えても、機械的強度

下が起こるようになるからである。The amount of the metal hydroxide compound to be added can be up to about 40 to 200 parts by weight, depending on the desired degree of flame retardancy. That is, if the amount is less than 40 parts by weight, sufficient flame retardancy cannot be obtained, and naturally higher flame retardancy can be obtained by increasing the amount. As described above, the polar group-containing E
By sharing with VA or EEA, it is possible to add a large amount up to about twice as much as the base resin. However, the upper limit is 2
The reason why the amount is set to 00 parts by weight is that even if the amount exceeds this, the mechanical strength (tensile strength, elongation, etc.), insulation properties, workability, etc., will decrease.

る。Further, in the case of the present invention having such a constitution, depending on the compounding of EVA or EEA, PP block copolymer and metal hydroxide compound, excessive addition, especially when the compounding amount of the metal hydroxide compound is large, etc. A phenomenon in which a white portion appears when bent, that is, a so-called whitening phenomenon may occur. In this case, the addition of hydrogenated SBR can effectively suppress the occurrence of the whitening phenomenon.

物の耐磨耗性も大きく改善される。Further, by adding the hydrogenated SBR,
Since the resin composition has elasticity, plastic deformation hardly occurs even when the resin composition is crushed, and deformation such as jumping-up of electric wires is reduced. In addition, the abrasion resistance of the resin composition is greatly improved by the proper addition amount.

ある。The amount of the hydrogenated SBR is
With respect to 100 parts by weight of the total amount of the EVA or EEA and the PP block copolymer, the amount of 5 to 80 parts by weight is less than 5 parts by weight. On the other hand, if it exceeds 80 parts by weight, it becomes too soft and the abrasion is reduced.
