The invention belongs to the technical field of polymer composite materials, and particularly relates to a TPEE composite material suitable for high-speed extrusion and a preparation method thereof. The TPEE composite material suitable for high-speed extrusion is prepared from the following raw material components in percentage by mass: 60 to 90 percent of a thermoplastic polyester elastomer A, 6 to 30 percent of a thermoplastic polyester elastomer B, 1 to 10 percent of polyethylene terephthalate, 0.1 to 2 percent of a high-speed extrusion accelerant, 0.1 to 0.5 percent of a copper inhibitor and 0.1 to 0.5 percent of an antioxidant. Through reasonable compatibility of thermoplastic polyester elastomers with different molecular weights, the TPEE substrate material with bimodal molecular weight distribution is formed, the thermoplastic polyester elastomer A with high molecular weight provides good mechanical properties and environmental stress cracking resistance, the thermoplastic polyester elastomer B with lo
