Flame-retardant coating by the layer-by-layer assembly of poly(vinylphosphonic acid) and polyethylenimine for ramie fabric
A novel intumescent flame retardant coating, consisting of poly(vinylphosphonic acid) (PVPA) as the acid source and branched polyethylenimine (BPEI) as the blowing agent, was constructed on the surface of ramie fabric by layer-by-layer (LbL) assembly to remarkably improve the flame retardancy of ramie. The PVPA/BPEI coating on the surface of individual fibers of ramie fabric pyrolyzes to form prot...

Synthesis of cerium phenylphosphonate and its synergistic flame retardant effect with decabromodiphenyl oxide in glass-fiber reinforced poly(ethylene terephthalate)
A lamellar cerium phenylphosphonate (CeHPP) was synthetized through reflux method and it was combined with decabromodiphenyl oxide (DBDPO) to prepare flame retarded poly(ethylene terephthalate) (PET) nanocomposites. Scanning electron microscopy (SEM) and X-ray diffraction (XRD) showed that CeHPP was a one-dimensional nanocrystal with the interlamellar distance of 1.57 nm. Thermogravimetric analysi...

Carbon nanotubes bridged cerium phenylphosphonate hybrids, fabrication and their effects on the thermal stability and flame retardancy of HDPE
Multiwalled carbon nanotubes (MWNTs) bridged cerium phenylphosphonate (CeHPP) hybrids (Ce-MWNTs) were facilely prepared through in situ introduction of MWNTs into the hydrothermal reaction system of CeHPP, aiming at enhancing flame retardancy of polymer. Morphological observations indicated that MWNTs were acted as bridges to connect CeHPP lamellas to form a consecutive structure. Moreover, due to...

Improvement of thermal properties and flame retardancy of epoxy-amine thermosets by introducing bisphenol containing azomethine moiety
A novel bisphenol 1, 4’-bis{4-[(4-hydroxy) phenyliminomethylidene] phenoxy} benzene (BHPB), which contains azomethine moiety and flexible aromatic ether linkage, was synthesized and introduced into the curing system composed of diglycidyl ether of bisphenol A (DGEBA) and diamine. The curing behavior of DGEBA/diamine changed dramatically due to the introduction of BHPB. The resultant epoxy thermos...

Synthesis and performance of three flame retardant additives containing diethyl phosphite/phenyl phosphonic moieties
Three novel intumescent flame retardants (IFRs) containing phosphorus and nitrogen based on Schiff bases, poly(phosphonate ester)s (designated as PAB, PEB, and PPB), were synthesized and characterized. Thermal stability and flammability properties of ethylene-vinyl acetate copolymer (EVA)/30%IFRs blends were investigated by thermogravimetric analysis (TGA), limited oxygen index (LOI), vertical bur...

Synthesis of cerium N-morpholinomethylphonic acid and its flame retardant application in high density polyethylene
Cerium N-morpholinomethylphonic acid (MMPA-Ce) with fibrous structure was synthesized via hydrothermal reaction between cerium nitrate hexahydrate and N-morpholinomethylphonic acid. The flame retardancy of high density polyethylene (HDPE) containing various amount of MMPA-Ce was investigated by cone calorimeter. The peak value of heat release rate (PHRR) of HDPE obviously decreased when adding MMP...

Improving the flame retardancy and mechanical properties of high density polyethylene-g-maleic anhydride with an organic metal phosphonate
Zinc N,N’-Piperazinebis(methylenephosphonic acid) (PPMPA-Zn) was melt blended with high density polyethylene-g-maleic anhydride (HDPE-MA) to fabricate flame retardant HDPE-MA/PPMPA-Zn composites. The thermal stability and flame retardancy of the composites were investigated by thermogravimetric analysis (TGA) and cone calorimetry. Incorporation of PPMPA-Zn did not obviously increase the ther...

121. Synthesis of a novel ionic liquid containing phosphorus and its application in intumescent flame retardant polypropylene system
A novel ionic liquid containing phosphorus ([PCMIM]Cl) was synthesized and characterized by FTIR, 1H NMR, 13C NMR and 31P NMR. Moreover, a new intumescent flame retardant (IFR) system, which was composed of [PCMIM]Cl and ammonium polyphosphate (APP), was used to impart flame retardancy and dripping resistance to polypropylene (PP). The flammability and thermal behaviors of intumescent flame-retard...

Effects of Layered Lanthanum Phenylphosphonate on Flame Retardancy of Glass Fiber Reinforced Poly(Ethylene Terephthalate) Nanocomposite
Effects of layered metal phosphonate, lanthanum phenylphosphonate (LaPP) on the thermal stability, ?ame retardancy and mechanical properties of glass-?ber reinforced poly(ethylene terephthalate) (PET/GF)/microencapsulated red phosphorus (MRP) systems were investigated. The results of transmission electron microscopy (TEM) measurements indicated that LaPP particles were homogenously dispersed in PE...
