EPOXY BINDING AGENT FOR REINFORCED PLASTICS Russian patent published in 2015 - IPC C08L63/00 C08K5/17 C08K5/41 

FIELD: chemistry.

SUBSTANCE: invention relates to the field of creating highly-strong composite materials based on fibrous fillers and epoxy binding agents, which can be used in the aviation industry, machine-, shipbuilding and other fields of technology. A binding agent includes dianic epoxy resin, the hardener diaminodiphenylsulphone and a modifier, the latter is represented by a mixture of thermoplastic modifiers, consisting of polysulphone and polyetherimide in a ratio from 1:3 to 3:1, with the following ratio of components, wt.p.: dianic epoxy resin - 100, mixture of thermoplastic modifiers - 1-25, diaminodiphenylsulphone - 35-50.

EFFECT: increase of toughness, strength and thermal resistance of the binding agent.
