The present invention discloses a TPEE/EVA/POE ternary blended closed-cell foaming material, which comprises the following raw materials: thermoplastic polyester elastomer (TPEE), ethylene-vinyl acetate copolymer (EVA), polyolefin elastomer (POE), compatibilizer, structure regulator, cell stabilizer, reinforcing agent, antioxidant, crosslinking agent, co-crosslinking agent and foaming agent. The preparation method comprises the following steps: Step 1: mixing and pelletization via a twin-screw extruder; Step 2: mixing in an internal mixer; Step 3: milling on an open mill; Step 4: sheet extrusion; Step 5: foaming; Step 6: cooling and shaping. The thermoplastic polyester elastomer TPEE and POE added to the foaming material of the present invention endow the composite material with the advantages of high melting point, excellent heat resistance, corrosion resistance and high tensile strength; meanwhile, the added TPEE also gives the entire composite material excellent elasticity and flexibility.
