Abstract

SiO₂ nano particle, through surface modification by silicane coupling agent KH-570, was successfully applied to make nano SiO₂/PP composite material by the melt-out blending process with twin-screw extruder. Effects of nano SiO₂ on the reinforcing and toughening of PP were studied by analyzing the material impact broken fracture, the crystal structure and the diameter of SiO₂ nano particle using SEM, XRD and TEM, respectively. Results showed that the impact strength and the tensile strength of nano SiO₂/PP composite material were improved apparently; the impact strength of PP was fracture was increased to 67% when the nano SiO₂ content was 4%; while the nano SiO₂ particle upon surface treatment will impose obvious heterogeneous nucleation function over PP crystal.
