Аннотация: The interaction of hexa methoxymethyl melamine with ammonium dihydrogen phosphate at 100Cwas investigated. It is shown that under the action of an adduct of ammonium dihydrogen phosphateand hexa methoxymethyl melamine, homo condensation of the latter occurs and encapsulation ofthe unreacted part of ammonium dihydrogen phosphate occurs. The maximum polymer yield outputcorresponds to the threshold at the atomic ratio N:P=1:1 in the combined product. Encapsulatedcomplex nitrogen-phosphorus-containing ame retardants were synthesized, which are used todetermine re resistance of epoxy resin cured with polyethylene polyamine. The optimal compositionof complex ame retardants (atomic ratio close to 1:1) were found, which provides the re resistanceof the composite material V0 (UL 94 test) and the oxygen index of 32-36% with a 20% mass fraction ofame retardants in the composite material. The formation of protecting char on the surface of thesubstrate in the ame of a gas burner allows the composite material to be used as a ame-retardantcoating for dierent constructions.
