The study of the influence of nitrogen and phosphorus-containing flame retardant on the thermal-oxidative degradation and combustion of glass fiber reinforced polyamide-6

Abstract

Mechanism of flame-retardant action f the mixe of triazine compound and red phosphorous in glass fiber reinforced polyamide-6 has been studied. Derived infrared spectra of char indicate of the interaction between red phosphorous and polyamide-6, that results in polymer surface carbonization. Compact carbonized layer protects virgin polymer layers from fuels and also acts as thermal barrier. Triazine compound leads to dilution of the fuels in combustion zone.
