Preparation of Organo Nanoclay Incorporated Polyamide/ Melamine Cyanurate/Nanoclay Composites and Study on Thermal and Mechanical Behaviours

A series of nylon 66/MCA/NC nanocomposites has been 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. The physico-mechanical properties such as density, surface hardness and tensile behaviours of PA 66/MCA/CN nanocomposites were investigated by universal testing machine (UTM). Thermal degradation of perisen nylon and nanocomposites was studied by 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. The effect of crysnanoclay on the storage modulus (E′), loss modulus (E″), and damping factor (tan ) as a function of temperature have been measured by dynamic mechanical analysis (DMA). The storage moduli of nanocomposites has been increased after incorporating crysnanoclay in polymer matrix.
