The Utility of Nanocomposites in Fire Retardancy
Nanocomposites have been shown to significantly reduce the peak heat release rate, as measured by cone calorimetry, for many polymers but they typically have no effect on the oxygen index or the UL-94 classification. In this review, we will cover what is known about the processes by which nanocomposite formation may bring this about. Montmorillonite will be the focus in this paper but attention...
متن کاملHigh-throughput techniques for the evaluation of fire retardancy
As new flame retardant (FR) approaches are developed they must be evaluated with conventional FR additives, processing additives, stabilizers, and fillers. In most cases this is done in a number of polymers, and a variety of processing conditions also must be optimized. Thus the development of new FR methods is a multi-parameter problem. A full-factorial approach to developing the structure–pro...
متن کاملEVA-layered double hydroxide (nano)composites: Mechanism of fire retardancy
Composites of ethyleneevinyl acetate copolymer with two different layered double hydroxides have been obtained by melt blending and these have been characterized by X-ray diffraction, transmission electron microscopy, thermogravimetric analysis, thermogravimetric analysis connected to mass spectroscopy and cone calorimetry. There is some small difference in dispersion between the zinc-containin...
متن کاملWood Nanotechnologies for Transparency, Fire Retardancy and Liquid Separation
In this thesis, wood nanotechnologies for transparent, fire-retardant and hydrophobic/lipophilic wood have been developed. There are two main parts; wood template preparation/processing concepts and materials design using these templates. In the wood template processing part, highly porous nanostructured wood templates are prepared. Relationships between processes and material structures are st...
متن کاملA novel method for manufacturing of wood flour/PP composites with better fire retardancy and mechanical properties
This study was conducted to investigate the effects of applying methods andamount of ammonium polyphosphate (0, 2 and 4 wt%) on fire retardancy andmechanical properties of wood flour/polypropylene composites. The resultsshowed that addition of fire retardant improved the mechanical properties such astensile and flexural strengths and fire retardancy of composites. But by increasingof fire retar...
