Abstract

Tris(3-nitrophenyl) phosphine (NPPh3), a flame retardant containing phosphorus and nitro group, is synthesized. And a novel flame retardant loading with NPPh3 and triphenyl phosphate (TPP) is prepared to flame-retardant acrylonitrile–butadiene–styrene (ABS). The effects of NPPh3 and TPP on the flammability of ABS are studied by various methods. The flame retardation of ABS/NPPh3/TPP composite is characterized by limiting oxygen index method and vertical and horizontal burning tests (UL-94). Compared with the systems with ABS/NPPh3 and ABS/TPP alone, ABS/NPPh3/TPP obtains a higher limiting oxygen index. Additionally, the flame-retardant effect of ABS/NPPh3/TPP in condensed phase is studied by thermogravimetric analysis (TG), scanning electron microscopy, and Fourier transform infrared spectroscopy (FTIR). The gases evolved during thermal degradation process in nitrogen are studied by means of thermogravimetry coupled with Fourier transform infrared spectroscopy (TG-FTIR). The results show that ABS/NPPh3/TPP exerts gas-condensed phase flame-retardant effect.
