| titleOfInvention | A kind of thermoplastic polyurethane elastomer resistant to low temperature and ultraviolet aging and preparation method thereof |
| abstract | The invention belongs to the technical field of polyurethane materials, and in particular relates to a thermoplastic polyurethane elastomer with low temperature and ultraviolet aging resistance and a preparation method thereof. The thermoplastic polyurethane elastomer comprises the following raw materials: diisocyanate, polyester polyol, and small molecular diol , Layered double metal hydroxides LDHs, antioxidants, catalysts, UV absorbers, free radical scavengers, solvents. The layered double metal hydroxide is added to the polyurethane elastomer of the present invention, so that the obtained thermoplastic polyurethane elastomer has good low temperature resistance, and also has excellent anti-ultraviolet performance, and improves the resistance of the thermoplastic polyurethane elastomer under low temperature conditions. UV radiation capability. The thermoplastic polyurethane elastomer of the present invention adopts solution polymerization, and is prepared by a two-step method, and the preparation process is simple and convenient. |
