Effect of Montmorillonite and Maleic Anhydride Grafted Polypropylene Content on Polypropylene/Wood Flour Composites
In this study the effect of nanoclay (0, 3 and 5 wt %) and grafted anhydride maleic with polypropylene (MAPP, 3 and 5 wt%) on physical and mechanical properties of polypropylene/wood flour nanocomposite was investigated. For manufacturing of these composites after melt compounding of the material they were converted to wood plastic granules in extruder and placed in hot press. The results showed that with increase of nanoclay physical (thickness swilling and water absorption) properties increases significantly but mechanical (bending and module of elasticity) properties increase up to 3 percent but after that gradually decreases. Also with incorporation of MAPP physical and mechanical properties of this nanocomposites improved and this positive effect was stronger for 5 percent MAPP than 3 one.
