In　order　to　obtain　retardant　ethylene-vinyl　acetate　(EVA)　foam　composites,　two　different　compounded　fire　retardant　consisting　of　expandable　graphite-ammonium　polyphosphate　(EG-APP)　and　expandable　graphite-ammonium　polyphosphate-thermoplastic　starch　(EG-APP-TPS)　were　added　to　prepare　alogen-free　fire　retardant　EVA　foam　composites　by　process　of　molten　blending　and　sulfuration　foam.　The　EG-APP/EVA　and　EG-APP-TPS/EVA　foam　composites　were　characterized　by　limit　oxygen　index　(LOI),　vertical　combustion　(UL-94),　thermal　analysis　mass　spectrometry　(TG-MASS)　and　scanning　electron　microscopy　(SEM)　test.　The　results　demonstrate　that　the　LOI　of　EG-APP/EVA　foam　composite　is　28.1%　and　the　flame　retardant　grade　reaches　to　UL-94　V-1　at　30wt%　total　loading　of　EG　and　APP　with　mass　ratio　of　1:4.　However,　at　30wt%　total　loading　of　EG,　APP　and　TPS　with　mass　ratio　of　1:4:1,　LOI　29.3%　and　UL-94　V-0　rating　are　obtained.　The　results　from　TG-MASS　and　SEM　tests　show　a　good　synergistic　effect　of　EG,　APP　and　TPS　in　solid　and　gas　phase.　©,　2015,　Beijing　University　of　Aeronautics　and　Astronautics　(BUAA).　All　right　reserved.
