Electrical insulating material based on cured epoxide resin contains nanofiller of organically-treated foliated clay with secondary, tertiary or quaternary ammonium ions having organic modifier groups

摘要

In insulating material comprising an epoxide resin (I), a hardener (II) and a nanofiller (III) with a height-width ratio not 40 at a thickness not 2 nm, (III) comprises an organically-treated clay, which is dispersed in (I) and is a clay mineral with foliated structure, treated with organic secondary, tertiary or quaternary ammonium ions having 2, 3 or 4 organic modifier groups bound to a nitrogen (N) atom.
