Article Preview

In order to improve the flame retardancy of wood-plastic composites,a new sandwiched composite is introduced in this paper with basic magnesium sulfated whisker(MOS) filled high density polyethylene(HDPE) as skin and wood flour filled HDPE as core.The oxygen index of the skin and the mechanical properties of the whole sandwiched composite are investigated. The results show that, the flame retardancy of the skin will be improved siginicantly when much MOS is used,and the skin containing 40wt% MOS has an oxygen index of 25.6%,in addition,the sandwiched composite in which both the mass contents of MOS in the skin and wood flour in the core are 40% has better mechanical properties than the traditional wood plastic composite(WPC) without any skin,and the sandwiched WPC is more fatigue-resistant.
