Techno-economic-environmental characteristics of polyurethane composite to thermal insulation for building with flame resistance: corroborative effect recycled of PVC and aluminum oxide

In this article, we present the results of the composite development obtained from polyurethane (PU), polyvinyl chloride (PVC), and aluminum anodizing sludge (AAS). The composites were prepared in different compositions and the properties were compared with PU. The apparent density, mechanical resis...

Description
Summary:In this article, we present the results of the composite development obtained from polyurethane (PU), polyvinyl chloride (PVC), and aluminum anodizing sludge (AAS). The composites were prepared in different compositions and the properties were compared with PU. The apparent density, mechanical resistance to compression, thermal stability study (UL94, DSC, calorimetric cone, SEM and DRX) and simulation of the energy use intensity (EUI) by Green Building Studio® (GBS) were analyzed. The specimens showed flame extinction in the horizontal and vertical flammability tests and less loss of mass when associated with AAS to PVC. Microscopy shows that for the flammability test of the composites a ceramic layer was formed due to the presence of AAS, which improved flame retardation and smoke suppression (UL94 and calorimetric cone). EUI for building using construction elements with composite (PVC 40 wt%) was 28% lower than EUI with ceramics, with CO 2 and cost reduction. The developed materials can contribute to the construction industry as a safe insulator, saving natural resources.
