Flame-retarding modification for ramie/benzoxazine laminates and the mechanism study
Flame retardant ramie/benzoxazine resin laminates were prepared and modified by ammonium polyphosphate (APP) and a nitrogen-phosphorous flame retardant (NEWRAY911). The results showed that the limiting oxygen index (LOI) values of the ramie/benzoxazine laminates could be ameliorated by the addition of APP, but did not achieve V0 level in UL94 test. Their mechanical strengths were also partially da...

Modification of Ramie Fabric with Metal Ions Doped Intumescent Flame Retardant Coating
Transition metal ions doped flame retardant coatings were constructed on the surface of ramie fabrics by layer by layer (LbL) assembly technique to investigate the possible cooperative action that could improve the flame retardant efficiency. It is found that these functional coatings consisting of poly(vinylphosphonic acid) (anionic layer) and branched polyethylenimine/cupric or zinc ions (cation...

Synthesis of novel poly(aminophosphonate ester)s flame retardants and their application in EVA copolymer
Two novel oligomeric phosphorous and nitrogen containing intumescent flame retardants, poly (amino phosphonate ester)s (PAPEs) were synthesized by reacting diethyl phosphite with polyschiff bases, which were obtained from the reaction of diamine with dialdehyde. The target PAPEs (designated as PAPE-e and PAPE-d respectively) were characterized by 1H-NMR, FTIR, elemental analysis, static light scat...

Design, synthesis and application of novel flame retardants derived from biomass
Biomass represents an abundant and relatively low cost carbon resource that can be utilized to produce platform chemicals such as levulinic acid. Novel oligomeric flame retardants poly(MDP-PDCP-MA)s (PMPMs) were designed and synthesized using diphenolic acid as one of the raw materials, which is derived from levulinic acid. To change the molar ratio of reactants, a series of PMPM samples with diff...

Synthesis and carbonization chemistry of a phosphorous-nitrogen based intumescent flame retardant
The char formation of intumescent flame retardant (IFR) plays a pivotal role for flame retarded polymer systems. In this work we studied the carbonization chemistry and mechanism of a polymeric phosphorous-nitrogen containing intumescent flame retardant named poly (diaminodiphenyl methane spirocyclic pentaerythritol bisphosphonate) (PDSPB). Thermogravimetric analysis (TGA), dynamic fourier transfo...

Relationship between the distribution of organo-montmorillonite and the flammability of flame retardant polypropylene
This paper studies the relationship between the distribution of organically modified montmorillonite (OMMT) and the flammability of flame retardant polypropylene which consists of polypropylene (PP), brominated epoxy resin-antimony oxide (BER-AO) and OMMT. Polypropylene-graft-maleic anhydride (PP-g-MAH) was used to increase the polarity of PP and aid the dispersion of OMMT. Two model systems, PP/B...

Synergistic effect of decabromodiphenyl ethane and montmorillonite on flame retardancy of polypropylene
Polypropylene (PP) is melt-compounded in a twin-screw extruder with surface-modified deca-
bromodiphenyl ethane/antimony trioxide (DBDPE/Sb2O3) and organically modified montmorillonite
(OMMT). The intercalation and dispersion microstructure of OMMT in the nanocomposites are investi-
gated by X-...
