“…For the two samples, the peak located at 3442 cm À1 was due to the stretching vibrations of the typical functional group of -OH. 31 The characteristic peak of 2892 cm À1 was attributed to the vibration of C-H. 32 For FR-lyocell, the characteristic peak at 1231 cm À1 corresponded to the P]O functional group. 33,34 The peaks of the P-O-C and O-P-O groups were appeared at 1041 cm À1 and 894 cm À1 .…”

“…Due to the catalytic effect of manganese dioxide, the pre-decomposition of EP and the degradation of metal oxides were promoted, and the MnO 2 @ZHS binary hybridization can promote the density and graphitization degree of carbon residues during combustion, thereby delaying the penetration of oxygen and combustible gases. Gao et al [ 72 ] used 2-carboxyethylphenylphosphoric acid (CEPPA) to modify ZHS and successfully synthesized the CEPPA–ZHS hybrid via a solution approach. After adding 10 wt% of CEPPA-ZHS into EP, the char residues and LOI values of CEPPA-ZHS/EP were significantly increased.…”

During the combustion of polymeric materials, plenty of heat, smoke, and toxic gases are produced that may cause serious harm to human health. Although the flame retardants such as halogen- and phosphorus-containing compounds can inhibit combustion, they cannot effectively reduce the release of toxic fumes. Zinc hydroxystannate (ZHS, ZnSn(OH)6) is an environmentally friendly flame retardant that has attracted extensive interest because of its high efficiency, safety, and smoke suppression properties. However, using ZHS itself may not contribute to the optimal flame retardant effect, which is commonly combined with other flame retardants to achieve more significant efficiency. Few articles systematically review the recent development of ZHS in the fire safety field. This review aims to deliver an insight towards further direction and advancement of ZHS in flame retardant and smoke suppression for multiple polymer blends. In addition, the fire retarded and smoke suppression mechanism of ZHS will be demonstrated and discussed in depth.

“…Tin-based smoke suppressant additives such as, for example, zinc hydroxystannate, ZnSn(OH) 6 (ZHS), act as smoke suppressant synergists by the combination of condensed phase mechanism (as a char promoter) and, in halogenated formulations, a vapor phase mechanism based on the volatilization of tin and zinc [11][12][13]. Many examples from the literature show the effectiveness of zinc-tin compounds in different combinations of polymer-FR system [14][15][16][17][18][19].…”

Synthesis of a Zinc Hydroxystannate/Sepiolite Hybrid Additive to Avoid Fire Propagation and Reduce Smoke Emission of EPDM Rubber Nanocomposites

A zinc hydroxystannate/sepiolite (SEPZHS) hybrid additive was successfully prepared following a facile wet chemical route synthesis where zinc hydroxystannate (ZHS) nanoparticles were grown on the sepiolite’s surface. SEPZHS particles have a fibrillar structure with ZHS nanoparticles homogeneously dispersed and with significantly smaller particle sizes than the synthesized ZHS nanoparticles alone. Sepiolite and SEPZHS were organically modified and introduced in a basic ethylene propylene diene monomer rubber (EPDM) formulation for cable to evaluate the nanocomposite behavior under direct fire sources. The results confirmed the synergistic effect of the hybrid SEPZHS additive in the formation of a most stable and efficient char barrier, thus improving the flame-retardant behavior of EPDM nanocomposite in terms of heat emission, with reductions of more than 40% in the peak of Heat Release Rate (cone calorimeter test), and smoke suppression, with more than 25% reduction in the Total Smoke Production and Smoke Density parameters (smoke chamber test). Moreover, the addition of sepiolite-based additives increased the mechanical properties (hardness) of the nanocomposites, as a result of the matrix reinforcement. This suggests that the SEPZHS hybrid additive may provide a promising option for a new, cost-effective, eco-friendly, yet efficient flame-retardant solution.
