Resumo: | In search of new materials from industrial waste, aiming at cost, efficiency and reduction of environmental liabilities, this study aimed to evaluate the physical, mechanical, acoustic and thermal characteristics of sandwich panels produced with sheets of Schizolobium amazonicum (paricá) and egg carton core made of cardboard, glued with adhesive phenol formaldehyde (FF), urea formaldehyde (UF) and interleaved the sheets glued with both. The panels were evaluated through thermal, acoustic, physical and mechanical tests. The FF and UF adhesives influenced the physical-mechanical properties of the panels. For thermal conductivity and thermal resistance, it was found that all panels met the normative requirements of NBR 15220 (ABNT, 2005) with emphasis on panels produced with FF. Therefore, the use of paricá sheets 32x12x0.2 cm (length, width and thickness, respectively) and egg box as a core with adhesive, proved to be promising for some uses in civil construction, in addition to adding value to the egg crate residues as thermal and acoustic insulators, can minimize the disposal of raw material in the environment. |
