doi:10.7523/j.issn.2095-6134.2011.5.004

Abstract

Abstract:

Ammonium polyphosphate and pentaerythritol were used to prepare halogen-free flame retardant BA-VAc copolymer emulsion. The flammability and thermal degradation properties of the copolymer were studied by using limited oxygen index (LOI), vertical burning test (UL-94), and thermo-gravimetric analysis(TG). Morphology of residues was detected by means of scanning electron microscopy. The copolymer has the best LOI value of 28.9 and passes UL-94 V- 0. TG data shows higher and more stable char residue in high temperature range.

Key words: vinyl acetate, butyl acrylate, halogen-free flame retardant, thermal stability
