various morphologies of silica nanoparticles were synthesized by a microwave-assisted pechini method. silica nanostructures were synthesized via a fast reaction between tetra ethyl ortho silicate and ammonia at presence citric acid and other effective agents in pechini procedure. then for preparation of polymer-matrix nanocomposites, sio2 nanoparticles were added to poly carbonate (pc) and poly...

Zinc borate is an important inorganic hydrate borate material, which can be used as a flame retardant agent and corrosion resistance material. This compound can loss its structural water content at higher than 290°C. Due to thermal stability; Zinc Borate can be used as flame retardant at high temperature process of plastic and gum. In this study, the ultrasonic reaction of zinc borates were stu...

An antibody-based analytical method for the detection of a chemical flame retardant using antibody fragments isolated from an alpaca has been developed. One specific chemical flame retardant congener, 2,2',4,4'-tetrabrominated diphenyl ether (BDE-47), is often the major poly-BDE (PBDE) congener present in human and environmental samples and that which is the most frequently detected. An alpaca ...

Abstract. Flame-retardant magnesium alloys containing calcium element are attracting attention from aircraft and automotive industries because of their low density high ignition temperature. Though thermomechanical treatments such as hot extrusion effective to increase mechanical properties, they cause an in cost. Present study focusses on commercial Mg-6Al-0.4Mn-2Ca Mg-9Al-1Zn-2Ca alloys. Simp...

In this paper, a wood coating based on waterborne polyurethane (WPU)/nano-cellulose crystalline (CNC)/Magnesium hydroxide (MH) was prepared. Efficient dispersion of MH in WPU presence 5 wt% CNCs observed by biological microscope leading to material with improved esthetic, thermal and fire-retardant properties mechanical performance. By thermogravimetric analysis (TG/DTG) comparison WPU, the max...

Magnesium hydroxide nanostructures as an effective flame retardant were synthesized by a facile and rapid microwave reaction. The effect of different surfactants such as cationic, anionic and polymeric on the morphology of magnesium hydroxide nanostructures was investigated. Nanostructures were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and Fourier transform in...

The intumescent retardant coating was fabricated by a combination of epoxy binder and flame-retardant ingredients for the steel plate. This paper investigates influence nanoclay content on improving fire properties fire-retardant coatings. performances coatings were determined test at 950oC one hour. degradation characterized Thermal gravimetric analysis (TGA). morphology, composition char stud...
