Abstract: The density, compression strength, bending strength, surface hardness and flame retardancy of polyurethane imitating wood with wood powder filling for furniture were tested. The effects of the addition content of wood powder and the mesh size of wood powder on the properties of polyurethane imitating wood were also studied. The results showed that: as the addition content of wood powder increased or the mesh size of wood powder enlarged, the compression strength of polyurethane imitating wood improved, but the bending strength and surface hardness descent slightly. The compression strength, bending strength and surface hardness had near linear increase along with a raise in the density of polyurethane imitatingwood with wood powder filling. After adding composite flame retardant, the flame retardancy of polyurethane imitatingwood improved linearly.
