摘要：

To solve the economic and environmental problems of thermoplastic polyurethane (TPU), waste tire powder (WTR) was applied to improve the physical properties of TPU. The waste tire rubber is a waste tire that has passed through a metactivator and is thermodynamically unstable, showing the shape of microcracked particles, and the cross linking is broken. The composites were prepared by simply mixing of TPU and WTR and a crosslinking agent using 2-hydroxyethyl methacrylate and dicumyl peroxide. The structure of WTR was observed by FTIR, and the glass transition temperature (10 of TPU and two kinds of TPU/WTR composites were measured by DSC. The modified TPU/WTR composites showed significant improvements in water resistance, chemical resistance, and swelling properties in polar aprotic solvents. As the storage modulus increased, the compression set was also remarkably improved.
