FIELD: chemistry.
SUBSTANCE: epoxy composition of hot hardening for manufacturing fibreglass plastic armouring for the reinforcement of concrete constructions includes an epoxy diane oligomer of brand ED-20 (100 wt.p.), a hardening agent - iso-methyltetrahydrophthalic anhydride (80 wt.p.) and a catalyst of the polymerisation reaction - 2,4,6,-tris(dimethylaminomethyl)phenol (1.5 wt.p.). It additionally contains carbon type nanomaterials (0.05-1.5 wt.p.), representing carbon nanotubes (CNT), or carbon nanofibres (CNF), or a mixture of carbon nanomaterials: fullerene, nanotubes, nanofibres (MCNM), or soot carbon (soot) as a modifying additive.
EFFECT: invention makes it possible to increase mechanical strength, elasticity modulus, alkali-resistance and temperature of vitrification of the obtained products.
