Abstract

Abstract Translated from Japanese (57)【要約】 【解決手段】 イソシアネート残基のうち、5%以上が 2,4’−ジフェニルメタンジイソシアネート残基であ るポリカルボジイミド共重合体を用いる絶縁被覆材。 【効果】 本発明方法による絶縁被覆材であるポリカル ボジイミド共重合体は、従来のポリカルボジイミド硬化 物の持つ高い耐熱性を維持したまま、従来にない可撓性 を発現するポリカルボジイミドであるため、これまで耐 熱性を必要としながらも従来のポリカルボジイミド共重 合体の硬化物では脆さのために適用できなかった電線や 電気基盤などの絶縁被覆に適用できる。 (57) Abstract: An insulating coating material using a polycarbodiimide copolymer in which 5% or more of isocyanate residues are 2,4'-diphenylmethane diisocyanate residues. The polycarbodiimide copolymer, which is an insulating coating material according to the method of the present invention, is a polycarbodiimide that exhibits unprecedented flexibility while maintaining the high heat resistance of a conventional cured polycarbodiimide. It can be applied to insulating coatings on electric wires and electric boards, etc., which were not applicable to conventional cured products of polycarbodiimide copolymers because of their brittleness, while requiring heat resistance.
