Abstract

To achieve effective flame retardant for acrylonitrile-butadiene-styrene(ABS) without halogen, synergistic effect was evaluated by incorporating phosphate with char body as coflame retardants. Two aromatic diphosphates (PFR), which are tetra-(2, 6-dimethy phenyl) resorcinol diphosphate(DMP-RDP) and tet-ra-(2, 6-dimethy phenyl) hydroquinone diphosphate (DMP-HDP), were synthesized and characterized by FTIR, 1H-NMR and TGA. A series of ABS/PFR/NP compounds were manufactured and experiment data were obtained by limit oxygen index(LOI) instrument and TGA under pure nitrogen. The results showed that the coflame retardants promoted crosslinking and char formation compared with control sample, especially, when ABS, PFR and NP was in the proportion of 75: 20: 5 and the LOI increased awfully. The TGA datum demonstrated that the more stable was the char generated in high temperature, the better flame retardancy was obtained.
