Improving the flame-retardant efficiency of aluminum hydroxide with fullerene for high-density polyethylene
The influence of fullerene (C-60) on the flame retardancy and thermal
stability of high-density polyethylene (HDPE)/aluminum hydroxide (ATH)
composites was studied. After the addition of three portions of C-60 to
an HDPE-ATH (mass ratio=100:120) composite, a V-0 rating in the UL-94
vertical combustion test was achieved, and the limiting oxygen index
increased by about 2%. The resu...

Flame-Retardant and Smoke-Suppressed Silicone Foams with Chitosan-Based Nanocoatings
Flexible silicone foams (SiFs) are high-performance but flammable materials that emit dense smoke in a fire. Two type of low-cost, eco-friendly nanocoatings, i.e., chitosan (CH)/ammonium polyphosphate (APP) and CH/montmorillonite (MMT), were fabricated on SiFs through a layer-by-layer (LbL) assembly. With seven bilayers (BL) of CH/APP coatings, the limiting oxygen index (LOI) increases from 20.2% ...

Flame retardation of cellulose-rich fabrics via a simplified layer-by-layer assembly
Due to the high cellulose content of cotton (88.0–96.5%), the flame retardation of cotton fabrics can be achieved via an approach for the flame retardation of cellulose. In this work, a facile water-based flame retardant coating was deposited on cotton fabrics by a ‘simplified’ layer-by-layer (LbL) assembly. The novel coating solution was based on a mild reaction between ammonium polyphosphate ...

Synergistic flame retardancy effect of graphene nanosheets and traditional retardants on epoxy resin
Novel non-toxic halogen-free flame retardants are replacing traditional flame retardants in polymer and polymer matrix composite structures. In this study, graphene nanosheet (GNS) is investigatedin combination with traditional layered double hydroxide (LDH), layered rare-earth hydroxide (LRH), and phosphorus-based flame retardant (DOPO) to enhance the flame retardancy of epoxy resin. A synergisti...

Synthesis of an intrinsically flame retardant bio-based benzoxazine resin
An intrinsically flame
retardant bio-basedbenzoxazine (DPA-PEPA-boz) resin was synthesized from bio-based diphenolic acid (DPA)using afour-step process.The monomer of DPA-PEPA-boz was characterized by FT-IR, 1HNMR and 13CNMR. The cure behavior of DPA-PEPA-boz was studied and compared with that of DPA based benzoxazine(DPA-boz) and DPA ester derivative (MDP)
basedbenzoxazine(MDP-boz)by means of non...

Superior flame retardancy of epoxy resin by the combined addition of graphene nanosheets and DOPO
In this paper, the thermal stability and fire retardant behavior of epoxy resin (ER) composites filled with graphene nanosheets (GNS) and 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (DOPO) were investigated. Addition of GNS and DOPO changed the decomposition pathway of ER. During combustion, DOPO played a key flame retardancy role in the gas phase and the char enhancement in the condensed p...

Burning behavior of irradiated PET flame-retardant fabrics impregnated with sensitizer
PET flame-retardant fabric with the presence of sensitizer trimethylolpropane triacrylate has been prepared by supercritical CO2 progressing method and then irradiated by electron irradiation. Irradiation changed the burning behavior of the PET flame-retardant fabric which had no dripping but burned up with the flaming and char forming. In order to explain the irradiation effect, XPS is used to in...

Synergism between montmorillonite and an intumescent flame retardant in EVA copolymer
Different flame retardant ethylene-vinyl acetate copolymer (EVA) formulations were prepared to evaluate the synergistic effect between organo-montmorillonite (OMMT) and a Schiff-base polyphosphate ester (PAB) on the combustion behavior of EVA. X-ray diffraction (XRD) and transmission electron microscopy (TEM) results revealed that montmorillonite platelets selectively dispersed in the PAB phase. E...

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...
