本発明は、クロロプレンゴムをベースとする組成物の燃
焼時の耐アーク性を向上させた耐アーク性電気絶縁組成
物に関する。DETAILED DESCRIPTION OF THE INVENTION [Purpose of the Invention (Industrial Field of Application) The present invention relates to an arc-resistant electrical insulation composition having improved arc resistance during combustion of a composition based on chloroprene rubber. .
（従来の技術）
クロロプレンゴムは他の汎用合成ゴムに比べて難燃性お
よび耐候性に優れており、その特長を生かして特に難燃
ケーブルのシース材料として使用されている。(Prior Art) Chloroprene rubber has superior flame retardancy and weather resistance compared to other general-purpose synthetic rubbers, and taking advantage of these characteristics, it is particularly used as a sheath material for flame-retardant cables.
しかしながらこのクロロプレンゴムは、燃焼時′の耐ア
ーク性に乏しいという難点があった。However, this chloroprene rubber had the disadvantage of poor arc resistance during combustion.
これは燃焼にともないクロロプレンゴムが炭化して電気
抵抗が低下するためであり、さらにクロロプレンゴムに
は、通常、難燃剤として三酸化アンチモンが配合される
が、この種の難燃剤はクロロプレンゴムの炭化を促進し
て難燃性を向上させるものであるため、このような難燃
剤の配合も耐アーク性を低下させる要因となっていた。This is because chloroprene rubber carbonizes as it burns, reducing its electrical resistance.Furthermore, antimony trioxide is usually added to chloroprene rubber as a flame retardant; Since the flame retardant promotes flame retardancy and improves flame retardancy, the inclusion of such a flame retardant has also been a factor in reducing arc resistance.
このようなりロロプレンゴムの燃焼時の耐アーク性を改

る。As such, as a method to improve the arc resistance during combustion of chloroprene rubber, conventionally, inorganic fillers such as white carbon and talc are blended to suppress carbonization during combustion of chloroprene rubber and to promote carbonization. A method has been proposed to minimize the amount of flame retardant added.

しかしながらこのような従来の方法では、耐アーク性を
十分向上させるために、無機充填剤を大量に配合する必

合には、実用上問題ない程度の難燃性を得ることが困難
であった。(Problem to be solved by the invention) However, in such conventional methods, in order to sufficiently improve arc resistance, it is necessary to incorporate a large amount of inorganic filler, which deteriorates mechanical properties and processability. In particular, there was a problem that the permanent elongation decreased significantly and the permanent set increased. This problem could not be solved even with the highest Mooney viscosity currently known as chloroprene rubber. Moreover, when a flame retardant is not blended, it is difficult to obtain flame retardance to a level that poses no problem in practical use.
そこで本発明はこのような従来の問題を解決しようとす

供することを目的とする。Therefore, the present invention aims to solve these conventional problems, and is based on chloroprene rubber that has improved arc resistance during combustion without deteriorating mechanical properties, processability, and flame retardancy. The object is to provide an arc-resistant electrical insulation composition.
［発明の構成］

、（ニ）加硫剤とを含有することを特徴としている。[Structure of the Invention] (Means for Solving the Problems) The arc-resistant electrical insulating composition of the present invention comprises (a) 100 parts by weight of chloroprene rubber, and (b) 50 parts by weight of silane-modified clay.
(c) 25 to 100 parts by weight of water-based clay, and (d) a vulcanizing agent.

り疎に形成されるためより大きな効果が得られる。Like other inorganic fillers, both the silane-modified clay (B) and the hydrophobic clay (C) suppress the formation of a carbonized layer during combustion of chloroprene rubber and improve arc resistance. For example, compared to plate-shaped talc, the carbonized layer is formed more sparsely, so a greater effect can be obtained.

ることができる。Moreover, the following effects can be obtained by the action of the silane-modified clay. That is, the mechanical properties and processability do not deteriorate, and the vulcanized density increases, so that good flame retardancy can be obtained even without adding a flame retardant such as antimony trioxide. This also means that the addition of flame retardants that promote carbonization is unnecessary or can be reduced in order to obtain a predetermined flame retardancy, and this also makes it possible to further improve arc resistance.
