EPOXY COMPOSITE MATERIAL Russian patent published in 2012 - IPC C08K3/04 C08L63/02 B82B1/00

Abstract RU 2455323 C2

FIELD: chemistry.

SUBSTANCE: invention relates to epoxy composite materials which can be used as coatings and binding materials. The epoxy composition consists of expoxy resin based on bis-phenol F, a polyanhydride type hardener and fullerene filler. The filler is either pure fullerene C₆₀ or a mixture fullerenes C₆₀/C₇₀, with the following ratio of components, wt %: fullerene C₆₀ or mixture of fullerenes C₆₀/C₇₀ 0.01-5-0.1; epoxy composition - the balance up to 100.

EFFECT: invention enables to increase strength by 10-15% while maintaining elasticity, impact strength by 5 times, temperature for softening, melting and decomposition in air, wherein density and moisture-absorption remain virtually unchanged.
