Реферат: Polyethylene is one of the most common materials in the modern world. Ultrahigh molecular weight polyethylene is one of them (UHMWPE, MW similar to 6x10(6)). All polyolefins including UHMWPE, are known to be combustible materials. Therefore, reducing the flammability of UHMWPE is an important objective. Currently phosphorus-containing compounds (PCC) are used as flame retardants for polyolefins. Earlier [1] the influence of triphenylphosphate (TPP, (C6H5O)(3)PO) as a flame retardant on the thermal decomposition and the flame structure of UHMWPE was investigated. However recently, the carbon nanoparticles were found to be a prospective competitor of PCC. In the present work graphite nanoplatelets (GNP) were used as a flame retardant. The purpose of this paper is to compare the effect of PCC and GNP on the thermal decomposition and flammability of UHMWPE. The objects of the study were an extruded UHMWPE/GNP mixture with the addition of 2.7 and 7.8% of GNP. The rate constants of the decomposition reaction of UHMWPE with GNP additives were obtained by DMSTA and TGA. The dependences of the oxygen index (LOI) and the ignition time on the loading of GNP additive were obtained by UL 94. Temperature profiles of flames of UHMWPE and UHMWPE/GNP were measured. The compositions of the combustion and thermal decomposition products were determined by GC/MS. The flame structure of extruded sample UHMWPE/GNP was investigated. The effects of PCC and GNP on the thermal decomposition and combustion of UHMWPE were compared. (C) 2013 International Association for Fire Safety Science.
