である。[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a flame-retardant electrical insulation composition that does not generate toxic gas when burned, and is particularly suitable for application to insulation materials and sheath materials for electric wires and cables. The present invention relates to flame-retardant electrical insulation compositions.
［従来の技術］
最近、ビルや発電所、各種プラント等で火災が発生した
場合を想定し、高い難燃性を有し、しかもこのような火
災時に有毒なハロゲン系ガスを発生せず、機器の腐食や
発煙性が極めて少ない難燃性電線・ケーブルが要求され
るようになってきた。[Conventional technology] Recently, in preparation for fires occurring in buildings, power plants, various plants, etc., we have developed equipment that has high flame retardancy and does not emit toxic halogen gases in the event of such a fire. There is a growing demand for flame-retardant wires and cables that exhibit extremely low levels of corrosion and smoke generation.

油性が望まれるようになってきた。Furthermore, in consideration of the actual usage environment, oil resistance comparable to that of neoprene rubber and chlorosulfonated polyethylene has come to be desired for insulating materials for electric wires and cables used for the Hiji Line, vehicles, and ships.
［発明が解決しようとする問題点コ
しかしこのような高度の性能を有する絶縁材料は開発さ
れておらず、種々検討が進められている状況にある。[Problems to be Solved by the Invention] However, no insulating material with such high performance has been developed, and various studies are currently underway.
本発明は上記に基いてなされたものであり、優れた耐油
性を有し、しかも燃焼時に有毒なハロゲン系ガスを発生
しない難燃性電気絶縁組成物の提供を目的とするもので
ある。The present invention has been made based on the above, and aims to provide a flame-retardant electrical insulating composition that has excellent oil resistance and does not generate toxic halogen gas when burned.
［問題点を解決するための手段］
本発明の難燃性電気絶縁組成物は、酢酸ビニル含有量が
２０重量％以上のエチレン−酢酸ビニル共重合体または

重量部以上含有することを特徴とするものである。[Means for Solving the Problems] The flame-retardant electrical insulation composition of the present invention is composed of an ethylene-vinyl acetate copolymer having a vinyl acetate content of 20% by weight or more or an alkyl acrylate content of 20% by weight or more. For 100 parts of ethylene-alkyl acrylate copolymer, 50 to 500 parts by weight of metal hydroxide, 0.5 parts by weight or more of carbon black, and 0.5 parts by weight of hydroxy lubricant.
It is characterized by containing at least part by weight.

チルアクリレート共重合体、エチレン−エチルアクリレ

などがあげられる。In the present invention, in order to improve oil resistance, an ethylene-vinyl acetate copolymer with a vinyl acetate content of 20% by weight or more or an ethylene-alkyl acrylate copolymer with an alkyl acrylate content of 20% by weight or more is used as a base polymer. I am using it. In this case, if the vinyl acetate content or alkyl acrylate content is less than 20% by weight, sufficient oil resistance cannot be achieved. Specific examples of the ethylene-alkyl acrylate copolymer include ethylene-methyl acrylate copolymer, ethylene-ethyl acrylate copolymer, and ethylene-butyl acrylate copolymer.
金属水酸化物としては、水酸化アルミニウム、水酸化マ
グネシウム、塩基性炭酸マグネシウム、ハイドロタルサ
イト類などがあげられる。これらはシランカップリン剤

処理したものを使用することにより、組成物の押出し加
工性を向上できる。Examples of metal hydroxides include aluminum hydroxide, magnesium hydroxide, basic magnesium carbonate, and hydrotalcites. The extrusion processability of the composition can be improved by using those that have been surface-treated with a silane coupling agent, a titanate coupling agent, a fatty acid metal salt, or the like.
金属水酸化物は、エチレン−酢酸ビニル共重合体または
エチレン−アルキルアクリレート共重合体１００重量部
に対して５０〜５００重量部の範囲で含有させる必要が
あり、５０重量部未満では目的とする難燃性を付与でき

ができなくなる。The metal hydroxide must be contained in an amount of 50 to 500 parts by weight per 100 parts by weight of the ethylene-vinyl acetate copolymer or ethylene-alkyl acrylate copolymer, and if it is less than 50 parts by weight, it will not meet the target difficulty. Flammability cannot be imparted, and if the weight exceeds 500, processability decreases and extrusion processing becomes impossible.
カーボンブラックは、燃焼時の炭化を促進して難燃性を
より向上させるために添加するものであり、０．５重量
部以上添加しないとこのような効果は発揮されない。Carbon black is added to promote carbonization during combustion to further improve flame retardancy, and this effect will not be exhibited unless it is added in an amount of 0.5 parts by weight or more.

属塩をいう。The hydroxy lubricant is added to prevent the composition from sticking during processing such as roll kneading or biaxial kneading, and by adding 0.5 parts by weight or more, processability can be significantly improved. Hydroxy-based lubricants are hydroxy-containing fatty acids or their metal salts, such as hydroxystearic acid, ricinoleic acid, barium hydroxystearate, calcium hydroxystearate, calcium hydroxylaurate, lithium hydroxystearate, barium ricinoleate, calcium ricinoleate, etc. means.

比較例１は酢酸ビニル含有量が本発明の規定値を下回る
エチレン−酢酸ビニル共重合体を用いた場合であり、耐
油性が劣る。比較例２は金属水酸化物の含有量が本発明
の規定値を下回る場合、比較例３はカーボンブラックを
含有しない場合であり、いずれも難燃性が不合格である
。比較例４は本発明で規定する以外の滑剤を使用した場
合、比較例５は滑剤の含有量が本発明の規定値を下回る
場合であり、いずれもロール加工性が悪い。Comparative Example 1 is a case where an ethylene-vinyl acetate copolymer having a vinyl acetate content lower than the specified value of the present invention is used, and the oil resistance is poor. Comparative Example 2 is a case in which the metal hydroxide content is less than the specified value of the present invention, and Comparative Example 3 is a case in which carbon black is not contained, and both of them fail in terms of flame retardancy. Comparative Example 4 is a case in which a lubricant other than that specified in the present invention is used, and Comparative Example 5 is a case in which the content of the lubricant is lower than the specified value in the present invention, and both have poor roll processability.
