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...

Construction of flame retardant nanocoating on ramie fabric via layer-by-layer assembly of carbon nanotube and ammonium polyphosphate
A new flame retardant nanocoating has been constructed by the alternate adsorption of polyelectrolyte amino-functionalized multiwall carbon nanotube (MWNT-NH2) and ammonium polyphosphate (APP) onto ?exible and porous ramie fabric. Scanning electron microscopy indicates that the adsorbed carbon nanotube coating is a randomly oriented and overlapped network structure, which is a promising candidate ...

Synergistic effects of expandable graphite and ammonium polyphosphate with a new carbon source derived from biomass in flame retardant ABS
A novel flame retardant system, ammonium polyphosphate (APP) and expandable graphite (EG) with a new carbon source, poly(diphenolic phenyl phosphate) (poly(DPA-PDCP)), derived from biomass has been proven to be effective in preventing melting drip and improving flame retardancy of acrylonitrile–butadiene–styrene copolymer (ABS) in this study, which was manifested by limiting oxygen ind...
