LOW-VISCOSITY EPOXY BINDER FOR REINFORCED PLASTICS WITH HIGH CRACK RESISTANCE AND HEAT RESISTANCE Russian patent published in 2021 - IPC C08L63/02 C08K5/06 C08K5/09 C08K5/3445 C08K5/42 C08J5/24

Abstract RU 2756806 C1

FIELD: composite materials.

SUBSTANCE: invention relates to epoxy binders used for the manufacture of composite materials by vacuum infusion, winding, pressing and other methods. An epoxy binder for reinforced plastics is proposed, including an epoxy-diane resin, a hardener, an accelerator, a thermoplastic modifier, and an active diluent. The epoxy binder contains isomethyltetrahydrophthalic anhydride as a hardener, 2-methylimidazole as an accelerator, polysulfone as a thermoplastic modifier, and furfuryl glycidyl ether as an active diluent. EFFECT: proposed binder has reduced viscosity, increased crack resistance and heat resistance.
