Biodegradable composite insulation material
The biodegradable composite insulation material is a composite of wood from the date palm tree (Phoenix dactylifera) and polylactic acid. The composite may have up to 50 wt % date palm wood powder of maximum particle size of 212 μm, the balance being polylactic acid (PLA). The composite may be prepared by melt blending the date palm wood powder with polylactic acid pellets in a twin screw extruder at 190° C., followed by compression molding the blend in a press or the like into the desired shape for building thermal insulation, and finally, annealing the molded product for three hours at 95° C. The composite material is biodegradable, thermally insulating, water-resistant and relatively strong.
