Effect of Mixing Conditions on Mechanical and Physical Properties of Nanocomposites Based on NBR/PVC/Nanoclay

Mixing conditions of NBR/PVC nanocomposites such as mixing temperature,rotor speed and mixing time are determining parameters in rheological,mechanical and morphological properties of the compound. Three levelswere chosen for each parameter using Design Expert software via Box-Behnkenmethod. The nanocomposite samples were melt-mixed in Brabender internal mixer. Theeffect of various mixing parameters such as mixing temperature, rotor speed and mixingtime was investigated by stress-strain and rheological curves. The TPE nanocompositeswere characterized by X-ray diffraction (XRD), transmission electronmicroscopy (TEM), dynamic mechanical thermal analysis (DMTA), and mechanicalproperties.
