description The invention discloses a high-strength and high-toughness reprocessable bio-based polyurethane elastomer with double antibacterial effects and a preparation method thereof. The bio-based polyurethane elastomer at least comprises the following raw materials: bio-based polycarbonate diol, diisocyanate, a green catalyst, a small molecule amine chain extender, a small molecule chain extender containing a tertiary amine structure and double-end halogen alkane. By adding a micromolecule amine chain extender, a micromolecule chain extender containing a tertiary amine structure and double-end halogen alkane, efficient broad-spectrum antibacterial performance can be achieved, and the material is endowed with the characteristics of high strength and high toughness. According to the high-strength and high-toughness reprocessable bio-based polyurethane elastomer with the double antibacterial effects and the preparation method thereof, the tensile strength of the obtained bio-based polyurethane elastomer can reach 64.4 M
