Properties of Acrylonitrile Styrene Acrylate Copolymer Modified Eucalyptus/Polyvinyl Chloride Composites

Eucalyptus/polyvinyl chloride (PVC) composites were prepared by extrusion molding with eucalyptus as filler, PVC as matrix, and different contents of acrylonitrile styrene acrylate copolymer (ASA). The effects of different ASA content on the mechanical properties, water absorption properties, and thermal stability of eucalyptus/PVC composites were studied. The morphology of the tensile section of the composites was observed by scanning electron microscopy (SEM). The results showed that the addition of ASA could improve the mechanical properties, heat resistance, and interfacial compatibility of eucalyptus/PVC composites. It also could reduce the water absorption of the composites. When ASA content was 10 wt%, the mechanical properties and heat resistance of eucalyptus/PVC composite were the best, and the water absorption in 24 h was the lowest.

Automated summary

Eucalyptus/polyvinyl chloride (PVC) composites with different contents of acrylonitrile styrene acrylate copolymer (ASA) were prepared by extrusion molding. The effects of ASA content on the mechanical properties, water absorption properties, and thermal stability of the composites were studied. The addition of ASA improved the mechanical properties, heat resistance, and interfacial compatibility of the composites, while reducing water absorption. The best mechanical properties and heat resistance were achieved when the ASA content was 10 wt%, with the lowest water absorption in 24 hours.
