The structure, thermal behavior and flame retardant properties of
polypropylene (PP) nanocomposites treated with complex flame retardants composed
of layered double hydroxides (LDH) and ammonium polyphosphate
(APP)/pentaerythritol (PER) intumescent flame retardant systems have been
investigated by XRD, TEM, LOI, UL-94, and TGA analysis. The results showed that
introduction of LDH nanofillers into the samples can obtain good flame retardant
synergistic effects with APP/PER additives at appropriate LDH loadings. Such
synergism between LDH and APP/PER in PP matrix can be explained by a proposed
condensed phase flame retardant mechanism. And based on this study, different types
of modified PP products were developed in a ten-thousand-ton scale to be used for the
automobile industries, such as car bumpers and dashboards. |
