The Effect of Mg(OH)2 Nanoparticles on the Thermal Stability and Flame Retardancy of Paraloid Nanocomposites
Paraloid-Mg(OH)2 nanocomposites were synthesized via sonochemical method. Nanostructures were characterized by XRD and SEM. Thermal stability behavior of paraloid filled with magnesium hydroxide was investigated by thermogravimetric analysis (TGA). The influence of Mg(OH)2 nanostructures on the flame retardancy of the paraloid matrix was studied using UL-94 analysis. Our r...

Thermal Degradation and Stability of Accelerated-curing Phenol-formaldehyde Resin
In order to study the thermal stability of accelerated-curing PF resin, the curing behavior of fresh PF resin was investigated in the presence of single accelerator of methylolurea derivatives (MMU), magnesium hydrate (Mg(OH)2), 25% aqueous solution of sodium carbonate (Na2CO3), and propylene carbonate (PC). Also their optimum combination was added in fresh PF resin. The thermal stability of cu...
متن کاملFlame Retardancy of Sorbitol Based Bioepoxy via Combined Solid and Gas Phase Action
Flame-retarded bioepoxy resins were prepared with the application of commercially available sorbitol polyglycidyl ether (SPE). The additive-type flame retardancy of the cycloaliphatic amine-cured SPE was investigated. Three-percent phosphorus (P)-containing samples were prepared with the application of the liquid resorcinol bis(diphenyl phosphate) (RDP), the solid ammonium polyphosphate (APP), ...
