| titleOfInvention | A kind of preparation method of bio-based high-performance water-based polyurethane resin and product thereof |
| abstract | The invention discloses a preparation method and a product of a bio-based high-performance water-based polyurethane resin, comprising the following steps: 1) placing a bio-based polyol, an internal emulsifier, and a divalent isocyanate in a three-necked flask and mixing, adding a catalyst, Under the set temperature and stirring speed, carry out the reaction to obtain a polyurethane prepolymer; 2) add a bio-based small molecule chain extender to the polyurethane prepolymer in step 1) to carry out chain extension reaction, and after the reaction is completed, add The neutralizer continues to be stirred, and then deionized water is added dropwise to the reaction solution for emulsification to obtain a bio-based high-performance water-based polyurethane resin. In the present invention, the bio-based small molecular chain monomer (cyclic dipeptide) of rigid structure is introduced into the vegetable oil-based water-based polyurethane segment, and the thermal stability and mechanical properties of the water-based polyurethane can be improved, and the solidity of the bio-based water-based polyurethane can be further improved. content. |
