Investigation of the effect of nanoclay and processing parameters on the tensile strength and hardness of injection molded Acrylonitrile Butadiene Styrene–organoclay nanocomposites

摘要: Abstract Polymer–clay nanocomposites have attracted considerable interest over recent years due to their dramatic improved mechanical properties. In the present study, compatibility of Acrylonitrile Butadiene Styrene (ABS) and organically modified montmorillonite nanoclay (Cloisite 30B) composition capability them are investigated. Polymethylmethacrylate (PMMA) in varying amount (0, 2, 4 wt%) is used as compatibilizer. order produce nanocomposite parts, material first compounded using a twin-screw extruder then injected into mold. The effect percentage processing parameters on tensile strength hardness parts also explored Taguchi Design Experiments method. Nanoclay content (in three levels: 0, 2 4 wt%), melt temperature 190, 200 210 °C), holding pressure 80, 105 130 MPa) time 1, 2.5 4 s) considered variable parameters. Moreover, distribution layers analyzed Wide Angle X-ray Diffraction (XRD) test. XRD results displayed that with presence PMMA, ABS matrix more exfoliated less intercalated dispersion mode. Adding PMMA leads remarkable increase fluidity during injection molding process. Results illustrated medium loading level (i.e. 2%) highest strength, while number belongs 4 wt% nanoclay. Obtained indicated has most important ABS–clay nanocomposites.
