The Influence of Diatomite Types and Compatibilizer Content on Properties of Diatomite-Wood Flour/Polypropylene Composites

Abstract:

Based on diatomite as modifier, maleic anhydride grafted polypropylene as compatibilizer, wood flour as reinforcing material, through single screw extruder, diatomite based wood plastic composite was prepared. The results show that: compared with one-grade-diatomite (OGD) and two-grade-diatomite (TGD), mechanical properties of the composites prepared by calcined diatomite (CD) are better, tensile strength and impact strength reached 46.9MPa and 20.1MPa. With respect to the diatomite types, it is more significant for the effects of MAPP mass on the mechanical properties of composites. The amount of MAPP was controlled in 4%, the mechanical properties of composites are better. The study of rheological properties showed that, the flow property of composites produced by calcined diatomite is better; the interface of the composite components is closer and more superior processability.
