Resumo
The large amount of plastic waste found in the environment, landfills, and
dumps boost research into the recycling of polymer materials, which could reduce
the amount of polymer discarded. In Brazil, the sector that most consumes polymers
is the civil construction that could consume recycled polymerswithout concerns with
the properties due to applications of low mechanical exigency. However, for applications
in this sector, it is necessary that the materials have some resistance to the
propagation of flames. This work discusses the flame retardance in nanocomposites
with recycled polystyrene matrix and particles of nanoargila, titanium dioxide, and
gypsum. The results of the X-ray diffraction (XRD), differential scanning calorimeter
(DSC), field emission scanning electronmicroscopy (FE-SEM), and flammability
test. The results showed that glycerol, added during recycling, can plasticize recycled
expanded polystyrene while maintaining the flame resistance properties of the
material with flame retardant. It can also be concluded that some particles may delay
the propagation of the flame in the composite.
