Effect on flame retardancy and mechanical properties of PA6 nanocomposites with addition of OMMT and PFR

摘要

The organically modified montmorrillonite (OMMT)/phosphorus polymeic flame retardant (PFR)/polyamide 6(PA6) nanocomposites were prepared via melt intercalation on a twin-screw extruder. The structure formed in nanocomposite system was investigated by Fourier Transform Infrared Spectroscopy (FTIR), X-ray Diffraction (XRD), and Transmission Electron Microscopy (TEM). Properties such as flame retardancy, notched impact strength, tensile strength, elongation at break and flexural modulus were studied by limited oxygen index (LOI) approach, UL94, and mechanical property test. The results of the studies indicated that flame retardancy and mechanical properties of PA6 nanocomposites were all reinforced due to addition of OMMT and PFR.
