Effect of Nano-Magnesium Hydroxide on Mechanical and Flame-Retarding Properties of SBR and PBR:A Comparative Study

摘要

Magnesium hydroxideMg(OH)2is one of the potential inorganic fillers.In this work,nanoparticles(37±5nm)of the magnesium hydroxide were prepared using matrix-mediated growth and control technique,and their size was confirmed by X-ray diffraction technique.Nano-Mg(OH)2-SBR and nano-Mg(OH)2-PBR composites with 2-10(w/w)filler loading were prepared by compounding on laboratory-scale two-roll mill and a compression molding machine.These composites were tested for tensile and physical properties,and the properties were compared with the composites of commercial Mg(OH)2.The incorporation of nanofiller improved the properties of nanocomposites.
