| titleOfInvention | Low-hardness high-resilience low-melting-point thermoplastic polyurethane elastomer and preparation method and application thereof |
| abstract | The invention provides a low-hardness high-resilience low-melting-point thermoplastic polyurethane elastomer, a preparation method and application thereof, wherein the low-hardness high-resilience low-melting-point thermoplastic polyurethane elastomer is prepared from the following components in parts by mass: the chain extender comprises polyester polyol, aromatic diisocyanate and binary small molecular alcohol, wherein the chain extender comprises 100: 16-33: 2-8, the polyester polyol is prepared by taking 1, 4-butanediol, 1, 6-hexanediol and small molecular polyol as raw materials and reacting with dibasic acid in the presence of a catalyst, and the molar ratio is as follows: 1, 4-butanediol: 1, 6-hexanediol: the ratio of the small molecular polyol to the polyester polyol is 2-500: 100: 1-20, and the number average molecular weight of the polyester polyol is 500-4000. The invention adopts a one-step method to synthesize the high-resilience thermoplastic elastomer, the hardness range of the elastomer is 45-80A, the melting point is 80-150 ℃, the elongation at break is 1000-1700%, the high-resilience thermoplastic elastomer can be applied to the production of high-resilience films, thin wires or nets woven by the wires, and the 100% fixed-tension resilience of the material is more than or equal to 90%. |
