Synergistic Flame Retardant and Suppression Smoke Mechanism of Cerium Phenylphosphonate and Decabromodiphenyl Oxide in Glass-fiber Reinforced Poly( 1,4-butylene terephthalate) Composites?
摘要
Abstract
Glass fiber reinforced poly(1,4-butylene terephthalate) (PET-GF)/ decabromodiphenyl oxide ( DBDPO)/cerium phenylphosphonate ( CeHPP ) composites were prepared by melt blending. Cone test was employed to investigate the comprehensive combustion behavior and the thermal gravimetric-infrared spectrometry( TG-FTIR) was used to analyze the release amount and component of volatile gases produced during thermal degradation. The scanning electron microtopography( SEM) of char residues was observed, and the elements and contents in char residues were tested by energy dispersive X-ray spectrometer ( EDX ) and X-ray photoelectron spectroscopy( XPS) . The experimental results showed that the compounding of CeHPP and DBDPO in PET-GF restrained the thermo-oxidative degradation of PET-GF/DBDPO/CeHPP composites, retarded the combustion of condensed phases and reduced the smoke release. CeHPP formed the continuous and compact carbon char during combustion, dispersing among the surface of polymer matrix and glass fibers and restricting DBDPO and its decomposition products in condensed phases. Therefore, the synergism flame retardant effects of gaseous phase and condensed phase were achieved, suppressing the smoke release to gaseous phase effectively.关键词
