Effect of a nanoclay/triphenyl phosphate hybrid system on the fire retardancy of polycarbonate/acrylonitrile–butadiene–styrene blend

Abstract

The effect of a hybrid system of nanoclay and triphenyl phosphate (TPP) on the fire retardancy of a polycarbonate (PC)/acrylonitrile-butadiene-styrene (ABS) blend was examined in this study. The nanoclay in the polymers decreased the peak heat release rates (PHRRs) with no significant effect on the ease of ignition and times to extinguishment. Improvements in the flame retardancy were observed only when nanoparticles were used with conventional flame-retardant (FR) additives. Thermogravimetric analysis (TGA), cone calorimetry, and limited oxygen index (LOI)/UL 94 (Underwriters Laboratory) testing were used to investigate the thermal degradation, fire behavior, and flammability of the materials. The results show that when we used a combination of TPP and nanoclay as an FR system, degradation of the polymer blends was reduced as the TGA curves shifted to higher temperatures. PHRR in cone calorimetry testing decreased from 1032 kW/m 2 for the PC/ABS blend to 300 kW/m 2 for the PC/ABS/(12% TPP-2% nanoclay) sample, and the LOI increased from 23 to 35%, respectively.

Flammability and thermal properties of polycarbonate /acrylonitrile-butadiene-styrene nanocomposites reinforced with multilayer graphene

“…Over the past few years, effect of several flame retardants such as triphenyl phosphate (TPP) [64], resorcinol bis(diphenyl phosphate) (RDP) [11], bisphenol A bis(diphenyl phosphate) (BDP) [11], bis(di-2-methylphenyl phosphate) (HMP) [65] and some fillers such as silica [66], boehmite [12], Talc [3] and graphite oxide [14] as an efficient antidripping agents for PC/ABS blend have been investigated. Nevertheless, additional research is required to investigation a synergetic influence of a flame retardant in PC/ABS-GNP nanocomposites to achieve a V-0 rating.…”

The effect of introduction of montmorillonite clay (MMT) on the elastic properties of polycarbonate (PC) composition with acrylonitrile-butadiene styrene (ABS)

“…PC/ABS blend nanocomposites have been chosen as a research object because of their wide use in numerous structural applications in civil engineering and transport. Besides it, in most of the previous researches on PC/ABS blend -nanoclay nanocomposites [12][13][14][15][16][17][18][19][20], generally experimentally determined results on the structure as well as rheological, mechanical, thermal and sorption properties have been analysed without trying to apply real theoretical analysis of elastic properties, which is under the scope of this study.…”
