EFFECT OF ANION OF POLYOXOMETALATE BASED ORGANIC-INORGANIC HYBRID MATERIAL ON INTUMESCENT FLAME RETARDANT POLYPROPYLENE

摘要

12-tungestocobaltic acid based organic-inorganic hybrid material, [Bmim]6CoW12O40 (CoW) was synthesized and applied as synergist in polypropylene (PP)/intumescent flame retardant (IFR) composites.The results showed that the PP composites with 16 wt％ IFR and 1 wt％ CoW achieves the UL94 V-0 rating and gets a LOI value 28.0.It suggests that CoW has good synergistic effects on flame retardancy of PP/IFR composites.
