Abstract The mechanical properties of wood flour/high-density polyethylene
composites (WPC) were improved by adding a small amount of nano-SiO2 to
obtain a network-structured WPC with a continuous honeycomb-like nano-SiO2
network. The wood flour was modified with a fire retardant (a mixture of sodium
octabonate and amidine urea phosphate) to improve its fire retardancy. The flexural properties, creep resistance, thermal expansion, and fire retardancy of the
WPC were compared to a control (WPCCTRL) without nano-SiO2 or fire retardant.
The flexural strength and modulus of the WPC containing only 0.55 wt.% nano-SiO2 were 6.6% and 9.1% higher than the control, respectively, while the… More >
