摘要：
Synergistic effect between modified oligomeric ammonium polyphosphate with p-methyl benzenesulfonate aluminum (APP@MeAl) and different component including copper oxide (CuO), charring agent (CFA) and hydroxyl group-containing phosphaphenanthrene derivative (DH) on flame-retardant poly(lactic acid) (PLA) were investigated. The results showed that PLA composites with the incorporation of 10 wt%APP@MeAl and 5 wt% DH achieved UL-94 V-0 rating and a LOI value of 28.4 %, superior than those of single APP@MeAl, and the combination by APP@MeAl with CuO or CFA. Thus, synergistic effect of APP@MeAl and DH was more effectively in the flame retardancy of PLA. The synergistic mechanism between APP@MeAl and DH in flame-retarding PLA were discussed in detail. As a result, this strategy provides a convenient and effect way to expand the application of oligomeric APP in preparing highly performance flame retardant polymer composites.
