Polypropylene is a thermoplastic polymer that has many industrial applications, but due to its poor properties, it is alloyed and combined with other materials to improve the impact properties and toughness. In this research, the simultaneous effect of filler, elastomer and compatibilizer on mechanical properties and impact of various polypropylene alloys were investigated. Using the box-behnken design, three factors were investigated in three different quantities: silica 9.6,3%, elastomer 20,15,10%, and polypropylene grafted maleic anhydride 100,50,0%.
Using this method, it is possible to predict the properties of this nanocomposite alloy with a composition of the percentage composition that is not produced
Made Tensile and impact tests were performed to investigate mechanical properties and scanning electron microscopy images to investigate the morphology of alloys. Microscopic results show that the alloy is a two-phase alloy with a dispersed particle size of about 200-400 nm, which increases with increasing elastomer content. With increasing elastomer levels, the amount elangation, toughness and impact strength increases, while the Young modulus and tensile strength decrease. On the other hand, the presence of compatibilizer has a positive effect on the properties by increasing the amount of nanosilica compared with its absence.
