Improving the Performance of Intumescent Flame Retarded Polypropylene with Nano-ZrO2

Abstract:

Article Preview

Melamine polyphosphate (MPP) and pentaerythritol(PTL) were used as intumescent flame retardants to improve the flame retardance of polypropylene(PP). As a synergistic agent, nano-ZrO2 was incorporated into the composites at different proportions. The synergistic effects of nano-ZrO2 were studied by cone calorimeter tests and thermal gravimetric analysis (TGA). Based on scanning electron microscopy (SEM) and Fourier transform infrared spectra (FTIR), it was evident that nano-ZrO2 efficiently promoted the formation of charred layers with phosphocarbonaceous structures and enhanced the flame retardance of the composites.
