Abstract: A multifunctional environmentally protective polyurethane composite material comprises a thermoplastic polyurethane; an environmentally protective additive including recycled polymer, plant fiber, mineral, or metal powder; and a thickening dispersant including natural rubber or synthetic rubber. By the thickening dispersant, the environmentally protective additive is uniformly added into the thermoplastic polyurethane to form the multifunctional environmentally protective polyurethane composite material. The environmentally protective additive can reduce the existing amount of waste or suppress increase of waste. With the use of the thickening dispersant and the environmentally protective additive, the multifunctional environmentally protective polyurethane composite material has advantages of light weight, good flowability, slip resistance, abrasion resistance, formability and low cost.
