Análise da concentração de resíduo de madeira, buriti e andiroba na produção de painéis poliméricos de média densidade.

Abstract

The agro-industrial residue is produced in a vast quantity and present potential to being reused in the development of new materials. There are reports of the utilization of Agro-industrial Lignocellulosic residues. However, there are few reports from processes of oil extraction. The present work aims at verifying the addition of residue obtained from the process of extraction of buriti and andiroba oil in medium-density panels, produced from Wood Residues and castor oil-based polyurethane matrix. The residue from buriti and andiroba in nature showed respectively 5,16% and 5,87% of moisture content. The sandwich panels utilizing buriti residue and monolayer produced with andiroba residue presented swelling content respectively around 5% and 10%, both conforming with the normative pattern for Medium-density panels (ABNT NBR 14810). However, they do not agree with the resistance module to static flexion and elasticity module. The panels produced with Andiroba residue are classified as V0, according to the norm ASTM 3801 for the burn of solid plastics in a vertical position. Although the addition of the residues of buriti and andiroba unleash in low swelling content, those provided a reduction in mechanical properties, indicating that it’1s necessary perform future works aiming to analyze the interaction of these types of residues with castor oil-based polyurethane matrix.
