Method for making faux wood material with multilayer pattern effect and mixed plastic material for use in the method

A method for making a faux wood material with a multilayer pattern effect, comprising:

• performing a compounding process on a thermoplastic elastomer material, a hard-segment-structure material and a foaming agent to form a 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 a density of the mixed plastic material and a thickness of 1-4 mm;
• stacking a plurality of preliminary sheets including the preliminary sheet up;
• performing, through a hot-pressing mold, a second foaming process on the stacked preliminary sheets until a density of the stacked preliminary sheets is equal to 40%-50% of the density of the mixed plastic material to form the faux wood material, wherein each of the preliminary sheets has two outer sides having a first density and an inner area having a second density different from the first density so that the faux wood material has a multilayer pattern differing in darkness and lightness.
