FIELD: chemistry.
SUBSTANCE: epoxy composition for infusion technology contains epoxy oligomer, selected from the group, which includes tri-tetrafunctional epoxy oligomers and eutectic mixture of, at least, two diamines, selected from the group, which includes diaminodiphenylsulphone, 3,3'-dichloro-4,4'-diaminodiphenylmethane, 4,4'-methylene-bis-(3-chloro-2,6,-diethylaniline) and 4,4'-methylene-bis-2,6,-diethylaniline, 4,4'-methylene-bis-2-isopropyl-6-methylaniline and 4,4'-methylene-bis-2,6,-diisopropylaniline. The invention also describes method of said composition obtaining.
EFFECT: invention makes it possible to obtain epoxy composition for obtaining bulky products by method of vacuum infusion with high complex of properties, realised by regulation of soaking speed, with variation of ratio of epoxy oligomers of various chemical structure and viscosity at different ratio of hardeners in mixture, as well as modes of hardening at different temperatures.
