The invention discloses a piece of TPU high-and-low-temperature membrane composite mesh cloth and a preparation method thereof. A TPU high-and-low-temperature membrane is compounded with the mesh cloth sequentially through manners of initial compounding and vacuum stripe suction, a traditional mesh cloth product is improved by the method, the advantages of excellent water repellent and wind resistance performance, high self-repairing capability, diversified surface effect, strong three-dimensional sense, the unnecessity of dyeing of the mesh cloth, the reduction of environmental pollution, excellent wear resistance and scratching resistance, good shaping performance after a shoe is produced, good durability and good deformation and damage resistance are achieved on the basis that the advantages of softness, light weight and comfort of a piece of traditional mesh cloth are maintained, and the demands on the functionality and diversity of traditional mesh clothe products and traditionalpolyurethane synthesis products by markets can be met.
