“…Catalytic reactivity and synergistic effectivity of REO might be determined by the filling status of the 4f shell of the rare earth element. The electronic configurations of Sm and La are 4f 6 5d 1 6s 2 5d 1 6s 2 [24]. Based on the lowest energy principle, when the 4f shell is fully filled, half filled, or completely empty, it has the lowest energy and so is most stable.…”

Synergistic effects of two kinds of rare earth oxides (REOs), samarium oxide (Sm 2 O 3 ) or lanthanum oxide (La 2 O 3 ) on the intumescent flame retardancy of Nylon 1010/ethylene-vinyl-acetate rubber (EVM) thermoplastic elastomers (TPE) were studied systemically. The limiting oxygen index (LOI) of intumescence flame retardant (IFR)-TPE increased from 30.5 to 32.5 and 34 when 0.5 wt% of IFR was substituted by La 2 O 3 and Sm 2 O 3 , respectively. Sm 2 O 3 showed higher synergistic effectivity than La 2 O 3 . Cone calorimetry tests confirmed that REOs enhanced flame retardancy of IFR-TPE. Smoke and CO production rate slightly decreased after incorporation of REOs as compared to IFRTPEs without REOs, indicating relatively reduced combustion hazard. By thermalgravimetric analyses (TGA), it was found that the presence of REOs promoted the esterification and carbonization process in low-temperature range while enhanced the thermal stability of IFR and IFR-TPEs in hightemperature range. X-ray diffraction (XRD) proved that the interaction of Sm 2 O 3 with IFR resulted in the formation of samarium phosphate (SmPO 4 ) with high-thermal stability. Rheological measurements showed that the complex viscosities of the IFR-TPEs increased with the addition of REOs, which might aid in suppressing melt dripping. For mechanical properties, incorporation of REOs led to higher modulus, similar tensile strength but lower elongation at break as compared to IFR-TPEs without REOs.

“…In recent years, intumescent flame retardant (IFR) [6][7][8][9][10][11][12][13][14][15][16] is well-known as a new generation of flame retardants in polypropylene and other polyolefins for some of their merits, such as very low smoke and toxic gases produced during burning, and antidripping property, which conform to the tendency of flame retardants' development.…”

Abstract. The purpose of in-tumescent fire retardant coating (IFRC) is to protect substrate from fire attack by limiting heat transfer. A range of coating formulations have been prepared using Bisphenol A epoxy resin BE-188 and polyamide solidifier H-2310 as two-part binder, ammonium polyphosphate (APP) as acid source, melamine (MEL) as the blowing agent, expandable graphite (EG) as carbon source and nano-boron nitride (BN) as inorganic nano filler. The filler was used to improve the performances of the APP-EG-MEL coating. The effects of nano-BN on the char morphology and thermal degradation were investigated by fire test, thermo gravimetric analysis (TGA), Fourier transform infrared spectroscopy (FTIR), Xray photoelectron spectroscopy (XPS) and field emission scanning electron microscopy (FESEM). The results showed that by substituting or reinforcing of 4% weight percentage of nano-BN, residual weight of the char increases by 23.82% compared to APP-EG-MEL coating without filler. Higher carbon content was obtained in the char and a more compact char was produced. The results indicated that nano-BN could be used as a filler to improve thermal stability of the APP-EG-MEL coating.
