Abstract

The aim of this study is to assess the feasibility of production of composite plastic with wood waste and wood powder with improved properties.Post-industrial waste to be used as base High Density Polyethylene (HDPE) as used plastic wood, called plastic wood waste (RMP) were benefited and mixed with wood dust residues (RPM). The mixtures were prepared with different percentages (by mass) RPM (0, 10, 20, 30 and 40%) in the twin-screw extruder model TeckTrill DCT 40, with L/D: 40 and ten temperature zones (more the head area), between 135°C and 220°C, with a processing speed of 60 rpm. The profiles obtained in the extruder were analyzed by torque, density, hardness, flow index and Scanning Electron Microscopy (SEM). The results torque, hardness and density showed a proportional increase with the RPM percentage for all compositions suggesting that the RPM load is acting as reinforcement and filling the HDPE matrix. As the melt index composite virgin HDPE/wood flour decreased with increasing RPM content, promoting the systems viscosity increase. This trend was observed for the composite RMP/RPM, probably due to the presence of additives RMP that keeps constant the viscosity of the system. The SEM analysis showed homogeneous materials.
