Paper Title:
Biodegradable Composites from Pinewood Sawdust and Polyvinyl Alcohol Adhesives
  Abstract

The objective of this study was to characterize the tensile strength (TS), tensile modulus of elasticity (TM) and shore hardness (HA) of biodegradable pinewood sawdust (PWS)/polyvinyl alcohol (PVA) composites as affected by press temperature, starch/PVA ratio and press time. PWS/PVA composites were prepared by hot press molding under different conditions. The results showed that the TS and TM values of the composite particleboard with press temperature of 140°C were greater than those of the composite particleboard with press temperature of 120, 160 and 180°C. HA decreased with the increase of press temperature. Effect of press time shows the similar trend as the press temperature. The composite particleboard pressed with 10 and 12 min possess the highest TS and TM respectively. when starch/PVA ratio increased from 0 to 17%, 33% and 50%, the TS and HA decreased, however, the tensile modulus increased because elongation at break of composite particleboard significantly decreased when starch/PVA ratio increased. Composites with PVA as matrix material was not reported before.
