Effects of NanoClay and Coupling Agent on Mechanical Properties of Picea Flour/Polypropylene/NanoClay Composite

Abstract

In this research, effect of nanoclay cloisite 30B and Coupling agent MAPP on mechanical properties of wood plastic composite that produced from picea flour/ poly propylene/ nanoclay inspected. for this propose, we used picea wood flour in constant level of 40%, MAPP in two levels of 2% and 4% and nanoclay in 4 levels of 0, 1, 3 and 5%. Next, wood plastic nano composite constructed by using of injection moulding method, and mechanical tests containing tensile, bending and impact performed on samples. Results showed that tensile strength and flexural strength and flexural modulus of composite enhance by increasing nanoclay and MAPP. Structural studies of wood plastic nano composite by diffraction of x ray also showed that distribution of nanoclay particles in polymer field is intercalation, and distance of between layers increase by enhancing of nanoclay particles amount.
