Fabrication and Properties of Nano-Al(OH)3/Mg(OH)2/Micro-Capsulated APP/PP Flame Retardant Composites

Article Preview

Abstract:

To improve the flame retardant performance of polypropylene (PP), three composites systems, nano-Al(OH)3/Mg(OH)2/PP, micro-capsulated ammonium polyphosphate (MCAPP)/PP, and nano-Al(OH)3/Mg(OH)2/MCAPP/PP had been developed and studied in this paper. Their flame retardant and mechanical properties were measured and analyzed. The results indicated that there existed synergistic effect of flame retardant among nano-Al(OH)3, nano-Mg(OH)2, and MCAPP. PP composites with the three flame retardants of 3 wt%, 9 wt%, 8 wt% respectively possessed the best integrated properties with OI value of 26.2 and little decrease in mechanical properties.
