“…Recently announced mixtures of phosphinates and other phosphorus compounds [10][11][12][13][14] have enabled Devan to develop for PP a novel flame retardant masterbatch. The aim of this article is to present the main results obtained by using this new mixture of phosphinates (MPh), in combination with classical nitrogen synergist agent, melamine cyanurate (MC), in different polypropylene textile structures.…”

Abstract:The efficiency of new phosphinates, in combination with melamine cyanurate, was studied using different polypropylene textile structures. The influence of different ratios up to a total amount of 6 wt% in the polypropylene fiber was investigated using the limiting oxygen index (LOI) and cone calorimeter method for research purposes, while the performances were correlated to the standards FMVSS 302 (Federal Motor Vehicle Safety Standards) and DIN 4102-l (Deutsches Institut für Normung) used more specifically for automotive and building sector.

“…Thus, the effect of flame retardancy of UPR-15AlPi/10ATH with continuous and thick char layer was better than UPR10AlPi/10ATH and UPR-15AlPi. A strong char layer is important to prevent the heat transfer and to provide effective protection for the substrate, so the formation of the efficient char for UPR-15AlPi/10ATH composite prevented the heat transfer between the flame and the substrate and thus protected the underlying material from further burning and pyrolysis [29]. As a result, the UPR-15AlPi/ 10ATH composite had a much higher LOI value and reached V-0 rating.…”

The synergistic flame retardant effects of AlPi and ATH in UPR were investigated. The flammability and thermal stability of UPR composites were evaluated with LOI, UL-94 vertical burning, MCC and TG. The structure and morphology of filler and char residues were examined with SEM and FTIR. The interaction between AlPi and ATH was observed when the mass ratio of AlPi and ATH was 3:2 and LOI value of flame-retarded UPR increased to 30 and UL-94 rating passed V-0; however, the SEM showed that AlPi and ATH have a good dispersion in UPR. The pHRR of UPR-15AlPi/10ATH was 241.6 Wg -1 , decreasing by 30.4 % compared with pure UPR. The experimental TG curve of AlPi/ATH in N 2 was lower than calculated one at the second stage and had lower char residue at 700°C, demonstrating interaction of AlPi and ATH during thermal degradation. The char residue of UPR-15AlPi/10ATH at 700°suggested that the interaction between AlPi and ATH strengthened the char-formation ability and thermal stability of UPR, so the SEM showed a strong and dense char surface. The FTIR of char residues at different temperatures showed that AlPi and ATH interactions changed the type of aluminum phosphates, making char residue of UPR/AlPi/ATH system increased eventually.

“…It containing acid sources can catalyze the polymer matrix into carbonates, which construct a continuous and compact barrier covering the entire material surface to isolate the oxygen, volatiles, and heat, thus making the fire self‐extinguish . Besides, OP can also act as a flame inhibitor in gas phase for TPU/OP and PP/OP composites . However, it is usually difficult to reach desirable flammability rating at a comparatively low loading level when OP is individually incorporated.…”

Flame‐retardant and thermal degradation mechanisms of melamine polyphosphate in combination with aluminum phosphinate in glass fabric‐reinforced epoxy resin

et al. 2018

A system based on a nitrogen–phosphorous flame retardant, melamine polyphosphate (MPP), and aluminum phosphinate (OP), was employed to flame‐retard glass fabric‐reinforced epoxy resin composites (GFEP). Surface modification was adopted to effectively solve the aggregation of MPP and OP particles in EP matrix during the curing process. The flammability characteristics and synergistic effect have been studied by using limiting oxygen index (LOI), vertical burning (UL94) tests, thermogravimetric analysis, and pyrolysis‐gas chromatography/mass spectrometry. The flame resistance tests indicated that the synergism system with an optimized ratio achieved UL94 V‐0 (1.6 mm) rating and the LOI value of 33.5%. The chemical composition and structure of residue were characterized by X‐ray photoelectron spectroscopy, Fourier transform infrared, and scanning electron microscopy. It is concluded that the synergistic system having a balance of nitrogen element and phosphorous element accelerate the carbonation of EP resin, which was in favor of the construction of compact and continuous charring structure, thus obtaining satisfactory flame retardance.
