Thermoplastic polyurethane elastomer/polyvinyl butyral (TPU/PVB) composite materials are prepared by melt-blending. The structure, the processing rheological properties, the thermal properties and the mechanical properties of the composite are studied via the FT-IR,the torque rheometer, the differential scanning calorimetry, the thermogravimetry and the tensile testing method. The results indicate that the TPU significantly improves the processing performance of the PVB. The balance torque of the composite is 7.2 N·m, when PVB:TPU is equal to 75:25 (weight), which is decreased by 42.4% comparing to the balance torque of the pure PVB. The processing performance of the TPU/PVB composites is improved by using dibutyl phthalate (DBP) as the plasticizer. The balance torque of the composite is decreased from 7.2 N·m to 4.5 N·m when the weight fraction of the DBP is 20% and PVB:TPU is equal to 75:25 (weight). The tensile strength of the composite is decreased by 13 MPa and and its elongation is increased by 138%, compared to that without adding DBP. The melting temperature is decreased by 10℃ and the decomposition temperature is increased by 18℃, comparing to the values of the pure PVB.
