| titleOfInvention | The method of extraction removing solvent in aqueous polyurethane production process |
| abstract | The invention discloses a kind of methods of extraction removing solvent in aqueous polyurethane production process comprising the steps of: extractant is in contact with the polyaminoester emulsion of non-desolventizing, then collects extraction phase raffinate phase respectively, can be obtained the polyaminoester emulsion of removing solvent；The extractant includes the positive structure or isoparaffin of C5~C30, the positive structure or isomeric olefine or polyene of C5~C30, the positive structure perhaps composition of isomery eneyne or above-mentioned substance of the positive structure or isomery alkynes of C5~C30 perhaps polyine C5~C30.The percent extraction of polymer solvent of the present invention is greater than 99%, and the residual quantity of polymer solvent is lower than 1% in aqueous polyurethane.The present invention be able to solve aqueous polyurethane production in desolvation process energy consumption it is higher, the defect of unstable product quality, be convenient for industrializing implementation. |
