This study proposes an innovative solution to flame-retard a sandwich composite made of unsaturated polyester resin, glass fibre skins and nonwoven core material. The strategy uses the material as flame-retardant carrier, while resin is also flame-retarded with aluminum trihydroxide (ATH). A screening fire-retardant performances materials, covered different types phosphorous additives (phosphat...
Abstract The flame-retardancy of enamelled wires was studied by using a cone calorimeter. characteristic parameters including time to ignition, heat release rate, total smoke and so on, were obtained. effect radiation flux on the flame retardancy analyzed. results show that is related content different components in composite insulation layer. Polyimide have good retardant performance, followed...
A sustainable, heat-resistant and flame-retardant cellulose-based composite nonwoven has been successfully fabricated and explored its potential application for promising separator of high-performance lithium ion battery. It was demonstrated that this flame-retardant cellulose-based composite separator possessed good flame retardancy, superior heat tolerance and proper mechanical strength. As c...
In this work, copper pyrovanadate (Cu3V2O7(OH)2(H2O)2) nanoparticles have been synthesized by a simple and rapid chemical precipitation method. Different copper-organic complexes were used to control the size and morphology of products. The morphology and structure of the as-synthesized products were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission elec...
BACKGROUND The study on the rare earth (RE)-doped layered double hydroxides (LDHs) has received considerable attention due to their potential applications in catalysts. However, the use of RE-doped LDHs as polymer halogen-free flame retardants was seldom investigated. Furthermore, the effect of rare earth elements on the hydrophobicity of LDHs materials and the compatibility of LDHs/polymer com...
Polyvinyl alcohol- (PVA-) based aerogels have attracted widespread attention owing to their low cost, eco-friendliness, and density. However, the applications of PVA-based are limited by flammability. In this study, a flame retardant, ammonium polyphosphate (APP), biopolymer, chitosan (CS), were added polyvinyl alcohol (PVA), polymer was further crosslinked using boric acid (H3BO3). PVA aerogel...
Over the last ten years a new trend of research activities regarding the flame retardancy of polymeric materials has arisen. Indeed, the continuous search for new flame retardant systems able to replace the traditional approaches has encouraged alternative solutions, mainly centred on nanotechnology. In this context, the deposition of nanostructured coatings on fabrics appears to be the most ap...
