摘要： A method for making a faux wood material with a multilayer pattern effect and a mixed plastic material for use in the method involve: performing a compounding process on a thermoplastic elastomer material, a hard-segment-structure material and a foaming agent to form the mixed plastic material; performing through an extruder a first foaming process on the mixed plastic material to form a preliminary sheet having a density equal to 10% to 20% of the density of the mixed plastic material and a thickness of 1-4 mm; stacking preliminary sheets up; and performing through a hot-pressing mold a second foaming process on the stacked preliminary sheets to form the faux wood material having a density equal to 40%-50% of the density of the mixed plastic material. Accordingly, through the two foaming processes, a multilayer pattern effect can be presented on the faux wood material due to its density difference.
