The invention provides a thermoplastic polyurethane material, a thermoplastic polyurethane film and an invisible car cover containing the thermoplastic polyurethane film, and relates to the technical field of polymer films. The thermoplastic polyurethane material is mainly prepared by compounding polyol, polyisocyanate, micromolecular polyol, a catalyst, a chain extender, an end-capping reagent, an antioxidant and a light stabilizer according to a specific ratio, and the thermoplastic polyurethane material prepared from the raw materials is a block polymer. The long-chain dihydric alcohol forms a soft segment, the hard segment is composed of various isocyanates and a chain extender, and the thermoplastic polyurethane material prepared from the soft segment and the hard segment has good hardness, strength, elongation and other properties; and the thermoplastic polyurethane film prepared from the thermoplastic polyurethane material has excellent strength and hardness, good elongation, good rebound resilience and the like.

    本发明提供了一种热塑性聚氨酯材料、热塑性聚氨酯膜及包含其的隐形车衣,涉及高分子薄膜技术领域。所述热塑性聚氨酯材料主要由多元醇,多元异氰酸酯,小分子多元醇,催化剂,扩链剂,封端剂,抗氧化剂和光稳定剂以特定的比例复配得到,由上述原料制得的热塑性聚氨酯材料是一种嵌段聚合物;其中,长链二元醇构成软段,硬段则是由多种异氰酸酯和扩链剂构成,由上述软段和硬段制得的热塑性聚氨酯材料具有很好的软硬、强度、伸长等性能,进而由上述热塑性聚氨酯材料制得的热塑性聚氨酯膜具优异的强度、硬度和良好的伸长率、回弹性等性能。
