In this study, flame retardant polyvinyl chloride (PVC) nanocomposites were
prepared successfully by melt blending in the internal mixer of PVC and
conventional fire retardants (aluminum hydroxide (ATH), zinc borate (ZB), and
nanoclay). The effect of flame retardant on the structure, mechanical, and fireresistant properties of PVC nanocomposites were investigated. The results showed
that in the nanocomposite with 1.5 wt% nanoclay, 5 wt% ATH, and 5 wt% ZB,
limiting oxygen index (LOI) reaches 31.2%, UL-94 V-0 rating was obtained (total
time of burn was 1.2 seconds). Moreover, mechanical properties of PVC
nanocomposite such as modulus of elasticity, tensile strength, and elongation at
break achieved good results, respectively 34.5MPa, 27.1MPa, and 295.0%.
