Preparation method of dispersion emulsion of high-alkali-resistance aqueous polyurethane |
| abstract |
The invention discloses a preparation method of dispersion emulsion of high alkali-resistant waterborne polyurethane, belonging to the technical field of waterborne polyurethane, and the technical scheme is characterized in that the production raw materials of the dispersion emulsion of the high alkali-resistant waterborne polyurethane comprise a polyol mixture and isocyanate, wherein the polyol mixture is formed by mixing polyether polyol HSH-305 and/or polyether polyol GY-3010E with polytetrahydrofuran ether glycol PTMG-2000 and polycaprolactone polyol T2205 according to a certain proportion; the polyurethane dispersion emulsion produced by the raw materials has improved alkali resistance, aqueous flexibility and tensile strength. |
