Abstract

Studies have been carried out on the effectiveness of the action of two types of fire retardants – graphene and an organic phosphorus-containing compound DOPO-THPO, introduced into an epoxy resin. The amount of fire retardants introduced was 0; 2 and 4% of the amount of epoxy resin. The efficiency was assessed by the oxygen index method (LOI). It was shown that for this epoxy resin, the introduction of graphene provided an increase in the oxygen index from 21 to 27%, and the introduction of the phosphorus-containing fire retardant DOPO-THPO – from 21 to 23%. With the simultaneous introduction of graphene (3%) and DOPO-THPO (1%), it was possible to achieve an increase in the oxygen index up to 28%.
