導電性が低い。However, although it is possible to make a paste-like composite of an alkali metal salt dissolved in polyethylene oxide or polypropylene oxide alone, polyethylene oxide alone has a high solubility in water (it is mixed into plastics as an antistatic agent). Since polypropylene oxide also dissolves in water, it is extracted with water and the antistatic effect gradually decreases.Also, when polypropylene oxide is used alone, the solubility of the alkali metal salt is low and the conductivity is low.

った。These complexes are alkali metal salts whose anions are halogen anions, halide anions, halide salts,
Organic acid anions are used, but perchlorates such as lithium perchlorate are preferred in order to obtain high conductivity. However, perchlorate is highly dangerous and can even explode when heated in mixtures with organic substances. For this reason, the amount of perchlorate added is low, up to several wL%. Furthermore, polymers based on polyethylene oxide or polypropylene oxide have poor thermal stability and decompose when heated, so they are more dangerous when they contain a large amount of perchlorate.

組成物である。That is, it is a block copolymer of polyethylene glycol and polypropylene glycol containing 8% or more and 25% or less of alkali metal perchlorate, and the content of ethylene oxide chains in the copolymer molecule is 10% or more and 50% or less. A stabilized paste-like conductive composition characterized by:

じる。A paste-like conductive assembled material containing a large amount of alkali metal perchlorate was thermally stable and had a higher decomposition initiation temperature than a single block copolymer. Although the reason is not clear,
It is presumed that intermolecular mutual utilization occurred between the alkali metal perchlorate and the block copolymer, resulting in stabilization. Further, this stabilization is better achieved by including water, and the decomposition start temperature of a paste-like conductive composition containing 13% or less of water increases. If the water content is more than 13%, the surface resistance will change by 1% over time when applied as an antistatic agent for plasti.

１ｇＭ度の点から難しい。As the cation of the alkali metal perchlorate applied to the present invention, sodium, potassium, lithium, and cesium are used, but lithium is preferable from the viewpoint of good solubility. The amount of alkali metal perchlorate added is 8% or more and 25% or less; if it is less than 8%, the stabilizing effect will be small, and if it is more than 25%, it will be difficult from the point of view of 1 gM degree.

（発明の効果）
本発明のベースト状導電性組成物は熱的に安定化されて
おり加熱分解温度が高く爆発の危険性も少ないので取り
扱いが容易である。(Effects of the Invention) The base-like conductive composition of the present invention is thermally stabilized, has a high thermal decomposition temperature, and has a low risk of explosion, so it is easy to handle.
また、特に過塩素酸リチウムを含むしのは高導電性であ
り且つ透明であるので電池などの電解質に使用したり、
透明性を必蒙とするプラスチックの帯電防止剤として使
用することができる。In addition, silica containing lithium perchlorate is highly conductive and transparent, so it can be used as an electrolyte in batteries, etc.
It can be used as an antistatic agent for plastics that require transparency.
また、親水性であるポリエチレングリフールの含有率が
低いので帯電防止剤としてプラスチックに練り込んでも
水による抽出がなく、特性が経時変化しない。更に水分
を適当量含むことにより加熱分解温度は更に上昇し安全
である。In addition, since the content of polyethylene glyfur, which is hydrophilic, is low, even if it is kneaded into plastic as an antistatic agent, it will not be extracted by water and its properties will not change over time. Furthermore, by containing an appropriate amount of water, the thermal decomposition temperature can be further increased and it is safe.
