TY - JOUR PY - 2011// TI - A Study on the Performance of Intumescent Flame-retarded Polypropylene with Nano-ZrO2 JO - Journal of fire sciences A1 - Xinlong Wang, A1 - Lianghu Wu, A1 - Jin Li, SP - 227 EP - 242 VL - 29 IS - 3 N2 - Melamine polyphosphate and pentaerythritol were used as intumescent flame retardants to improve the flame retardance (FR) of polypropylene. 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. Based on Fourier transform infrared spectra, X-ray photo-electron spectroscopy, and scanning electron microscopy, it was evident that nano-ZrO2 efficiently promoted the formation of charred layers with phosphocarbonaceous structures and enhanced the FR of the composites.
