AbstractPhosphorus-containing tri(acryloyloxyethyl) phosphate (TAEP) was blended with triglycidyl isocyanurate acrylate (TGICA) in different ratios to obtain a series of UV curable intumescent flame retardant resins. The fire properties of the cured films were characterized by limited oxygen index (LOI), UL 94 and Cone Calorimeter. A distinct synergistic effect was found between TAEP and TGICA. The sample TAEP2 had the highest LOI (44) value among all resins. The cone calorimeter results showed that the sample TAEP2 had the lowest peak heat release rate (297 KW/M2). The thermal degradation was monitored by thermogravimetric analysis (TGA) and real-time Fourier transform infrared spectroscopy (RT-FTIR). The degradation mechanism is suggested in which the phosphate group in TAEP first degraded to form poly(phosphoric acid)s, which further catalyzed the degradation of the material to form char with emission of nitrogen volatiles from TGICA, leading to the formation of expanding char.

Set Up

The integration of intumescent flame-retardant (IFR) additives in natural fiber-based polymer composites enhances the fire-retardant properties, but it generally has a detrimental effect on the mechanical properties, such as tensile and flexural strengths. In this work, the feasibility of graphene as a reinforcement additive and as an effective synergist for IFR-based flax-polypropylene (PP) composites was investigated. Noticeable improvements in tensile and flexural properties were achieved with the addition of graphene nanoplatelets (GNP) in the composites. Furthermore, better char-forming ability of GNP in combination with IFR was observed, suppressing HRR curves and thus, lowering the total heat release (THR). Thermogravimetric analysis (TGA) detected a reduction in the decomposition rate due to strong interfacial bonding between GNP and PP, whereas the maximum decomposition rate was observed to occur at a higher temperature. The saturation point for the IFR additive along with GNP has also been highlighted in this study. A safe and effective method of graphene encapsulation within PP using the fume-hood set-up was achieved. Finally, the effect of flame retardant on the flax–PP composite has been simulated using Fire Dynamics Simulator.
