| titleOfInvention | Biological thermoplastic polyurethane elastomer and preparation method thereof |
| abstract | The invention discloses a biological thermoplastic polyurethane elastomer and a preparation method thereof, the biological thermoplastic polyurethane elastomer has high biological base content and excellent comprehensive performance, and comprises the following components: a) 30-95 wt% of a polyol component, wherein the number average molecular weight of the polyol is 800-6000 g/mol, and the polyol contains 50-100 wt% of bio-based polyester polyol; b) 0-25 wt% of a chain extender component, wherein the chain extender contains 50-100 wt% of a bio-based chain extender; c) 5-45 wt% of a diisocyanate component, wherein the diisocyanate component comprises 10-60 wt% of a bio-based diisocyanate; d)0.001 to 0.1 wt% of a catalyst component, wherein the catalyst contains 50 to 100 wt% of a non-tin environment-friendly catalyst. a) C) the sum of the biobased contents of the components is greater than or equal to 50 wt%. The thermoplastic polyurethane elastomer can be prepared by a one-step method, a batch method or a prepolymer method. |
