| titleOfInvention | Solvent-resistant polyurethane elastomer and preparation method thereof |
| abstract | The invention belongs to the technical field of polyurethane application, and particularly relates to a solvent-resistant polyurethane elastomer and a preparation method thereof. The solvent-resistant polyurethane elastomer is prepared from a component A, a component B and a component C in a mass ratio of 100: 20-30: 3-15, wherein the component A is prepared by carrying out vacuum dehydration on polyester polyol at the temperature of 100-120 ℃, the polyester polyol is polysuccinate polyester polyol containing ethylene glycol and diethylene glycol, the mole percentage of the ethylene glycol in the total amount of the ethylene glycol and the diethylene glycol is 50-80%, the component B is isocyanate, and the component C is a curing agent component, and is prepared by mixing an alcohol chain extender after dehydration with a catalyst. Compared with the common polyurethane elastomer, the solvent resistance of the solvent-resistant polyurethane elastomer is improved to a certain extent; the invention also provides a simple and feasible preparation method. |
