一般にプラスチックなどの絶縁体、Ge1Si、カーボ
ンブラック、グラファイトなどの半導体、金属などの導
電体はそnぞn特有の体積抵抗率を持っている。In general, insulators such as plastics, semiconductors such as Ge1Si, carbon black, and graphite, and conductors such as metals each have a unique volume resistivity.
上記絶縁体の体積抵抗率は108Ω・em 以上、半
導体の体積抵抗率はio−’〜108Ω・cm、導電体
の体積抵抗率は10−3Ω・cm以下である。The volume resistivity of the insulator is 10 8 Ω·em or more, the volume resistivity of the semiconductor is io−′ to 10 8 Ω·cm, and the volume resistivity of the conductor is 10 −3 Ω·cm or less.
そして、こnらの電気材料の体積抵抗率は温度変化によ
って変化するものである。The volume resistivity of these electrical materials changes with temperature changes.
即ち、絶縁体の体積抵抗率は温度が上昇すると減少し、
反対に半導体と導電体との体積抵抗率は一般に温度上昇

ようにその体積抵抗率は温度上昇によって上昇する傾向
にあった。That is, the volume resistivity of an insulator decreases as the temperature increases;
Conversely, the volume resistivity of semiconductors and conductors generally increases as the temperature rises. In particular, conductive materials made by mixing carbon such as carbon black with plastic are used in various electrical devices because they are lightweight, easy to work with, and inexpensive. As mentioned above, the volume resistivity of conductive materials also tends to increase as the temperature increases.
そのため、このカーボンブラック等を混練してなる導電
材料を使用した電気又は電子機器はその特性が温度によ
って変化することになり、一定の性能を保ち得ない欠点
があった。Therefore, electric or electronic equipment using a conductive material made by kneading this carbon black or the like has the disadvantage that its characteristics change depending on the temperature, making it impossible to maintain constant performance.
本発明は前記のような従来のもののもつ欠点を排除して

ある。It is an object of the present invention to eliminate the drawbacks of the conventional materials as described above and to provide a plastic 4v electrical material whose volume resistivity is not affected by temperature changes.

5し〕矛にする。The plastic used for the present invention is a thermoplastic such as polyethylene, polypropylene, or ethylene-propylene copolymer, and the content of conductive carbon is 5.
The content of talc, which is an inorganic filler, is 5 to 50%.
5) Make it a spear.

とんど影響を受けないため、標準抵抗的な役割をはなす
効果を有している。The reason for setting the conductive carbon content to 5 to 50 is that if it is less than 5, the conductivity of the plastic conductive material will deteriorate, and if it is more than 50, it will be difficult to create a plastic conductive material. .・Also, the reason why the content of Merck, which is an inorganic material, is set to 5 to 50 g is because if it is less than 5 g, the volume resistivity of the plastic conductive material will be easily affected by temperature changes, and if it is more than 50 g, the plastic conductivity will be This is because the plastic conductive material of the present invention has a volume resistivity that is almost unaffected by temperature changes, and electrical or electronic equipment using this conductive material will be difficult to produce due to temperature changes. It has the effect of maintaining stable performance even when Furthermore, since the volume resistivity of the plastic conductive material of the present invention is almost unaffected by temperature changes, it has the effect of fulfilling the role of a standard resistor.
