Translated Title

Synthesis,application of a halogen-free flame retardant with phosphaphenanthrene group

Translated Abstract

2-(6-oxido-6Hdiben-(c,e)(1,2)-oxaphosphorin-6-yl)-1,4-bis(5’,5’-dimethyl-1,4-dioxaphosphori-nanyl-2-oxy)benzene　(DPPOBQ),a　novel　halogen-free　flame　retardant　with　phosphaphenanthrene　group,was　synthesized　via　phospous　oxychloride,neopentyl　glycol,9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide　(DOPO)and　1　,4-benzoquinone　by　a　three　step　reaction.And　the　structure　of　DPPOBQ　was　characterized　and　studied　by　mass　spectrometry　(MS),elementary　analysis,fourier　transform　infrared　spectra　(FT-IR),1　H　and　31P　nuclear　magnetic　resonance　spectrum　(1H-NMR,31P-NMR),respectively.Then　the　flame　retardance　in　EVA　foam　composites　was　discussed.The　results　of　TG-Mass　show　that　the　flame　retardant　has　a　high　thermal　stability　and　excellent　char-forming　ability.The　5%　weight　loss　temperature　of　title　compound　was　above　260.2　℃　and　the　char　yield　was　about　19.1%　at　1　000　℃.
