“…polyphosphate and LF. For LFPN and APP, it should be gured out there were two subpeaks at 400.7 eV for NH 4 + and at 398.5 eV for -NH-in the N1s spectra, respectively(P. K. Zhang et al, 2018). However, there were many differences for the two subpeaks between LFPN and APP.…”

Cotton fabric is widely used in many occasions, but it is flammable with high fire risk. To meet the great fire safety demands of cotton fabric, a novel lignocellulosic-based P-N synergistic (LFPN) flame-retardant coating with high efficiency and environment friendly was developed via mechanochemistry strategy in the aqueous phase. The characterisation results showed the stable P-O-C bond formed to bind both lignocellulosic fibre and ammonium polyphosphate (APP). Meanwhile, LFPN has an excellent dispersion in water with a nanometer-scale enveloping rod structure. The cotton fabric treated by the LFPN coating showed outstanding flame-retardant properties, the peak heat release rate (PHRR) was reduced by 77% and the residue mass was increased by 259% compared with control cotton fabric. And there was a self-extinction phenomenon during the flammability test of flame retardant cotton. Based on the analysis of the combustion and pyrolysis process, a gas-condensed two-phase flame retardant mechanism model was proposed, which could be used to explain the action process of LFPN for cotton fabric during combustion.

“…Several studies have focused on the development of APP-based systems to reduce the flammability of polyurethane foams. Zhang et al [32] synthesized hydroxyl-functionalized APP (HAPP) via a cation exchange reaction in order to improve by chemical cross-linking the fire behaviour of a solvent-free two-component polyurethane. The results of LOI, UL-94 and cone calorimeter analyses suggested the effectiveness of the HAPP as FR, highlighted by the increased LOI value to 25.7%, V-1 classification and decreased pHRR, THR and TSP.…”

Halogen-free flame retardants for application in thermoplastics based on condensation polymers

et al. 2019

View full text Add to dashboard Cite

Future materials in the field of thermoplastics require a lower impact on the environment. Actual thermoplastic materials also require "greener" additives for thermal and fire resistance profile. In this work, some of the recent solutions for halogen-free flame retardants were discussed in the context of viable routes with economical and industrial relevance. The fire retardant mechanism was discussed in order to imagine new solutions for future additives. Some of the main (inorganic, organic or hybrid) flame retardants can be used as common platform for the next classes of thermoplastic composites (synthetic, natural, or bio-based). The new generation of flame retardants (based on the emerging solutions) will have to surpass two major barriers: the cost effectiveness and the need for high concentration (which usually affects other properties).
