preparation of organo nanoclay incorporated polyamide/ melamine cyanurate/nanoclay composites and study on thermal and mechanical behaviours

this study focuses on achieving high stiffness/strength and good fr characteristic of nylon 66/mca/nc nanocomposites, prepared via melt compounding by twin screw extruder. a synergistic effect of flame retardant systems based on melamine cyanurate and zinc borate on the flammability and mechanical behaviours of crysnanoclay reinforced nylon 66 nanocomposites have been reported. mechanical test results indicated that all composites exhibited higher stiffness than pristine nylon 66. thermal characteristics were performed using thermogravimetric analysis (tga), and dynamic mechanical analysis (dma). tga thermograms indicate a significant increase in thermal stability after incorporation of flame retardants additives to nylon 66 matrices. a slight reduction in hdt and marked reduction in izod impact strength after incorporation of flame retardant into nylon 66/mca/nc nanoomposite was observed.
