Studies on Friction and Mechanical Properties of High Density Polypropylene (HDPP) Filled with Modified Talc
Talc was modified by aluminate coupling agent (ACA) before filling it into high density polypropylene (HDPP) to prepare talc/HDPP composites.Scanning electron microscopy (SEM),wear testing machine,electronic universal testing machine,and impact testing machine were used to analyze the surface modification and the effects of modified talc on friction and mechanical properties of modified talc/HDPP composites.The results indicate that after modified the lamellar structure of talc particles are open and the dispersion of particles are improved,and the edges and comers of surface become softer.Friction properties indicate that when the talc content is 8 wt%,both μ and K are at a lower value,which show that have better wear resistance.The frictional surface is relatively smooth and no furrow trace has found.Mechanical properties show that with talc content increasing,tensile strength and flexural strength of composites increase.
