Effect of Sb₂O₃ Particle Size and Filling Amount on Crystallization and Mechanical Properties of Sb₂O₃/PP Composites

Abstract:

In this paper, Sb₂O₃/PP composite specimens were prepared by ball milling and melt blending. The effects of Sb₂O₃ particle size and filling amount on the toughening, reinforcing effect and crystallinity of PP composites were analyzed by notch impact test, tensile test, SEM, XRD and DSC characterization. The experimental results show that the filling of Sb₂O₃ particles can improve the mechanical properties and crystallization properties of Sb₂O₃/PP composites. With the increase of filling amount of Sb₂O₃ particles, the tensile strength and impact strength of Sb₂O₃/PP composite increased first and then decreased. When the content of Sb₂O₃ is 2 wt.%, the tensile strength and impact strength of Sb₂O₃/PP composites reach the maximum. When the filling amount is the same, the crystallization and mechanical properties of nanoSb₂O₃/PP composites are better than those of micron Sb₂O₃/PP composites.
