| titleOfInvention | Cationic compound aqueous polyurethane-based black dye and preparation method thereof |
| abstract | The invention discloses a cationic complex waterborne polyurethane-based black dye and a preparation method thereof, wherein polymer polyol and a hydrophilic chain extender are mixed, heated to 100-140 ℃, and dehydrated for 1-2 hours under the condition that the vacuum degree is less than or equal to 0.1 MPa; introducing nitrogen, cooling to 50-70 ℃, adding a polyisocyanate monomer and a catalyst, heating to 80-100 ℃, and keeping the temperature for 2-4 hours; dissolving micromolecular red, blue, purple and yellow dyes in a solvent, sequentially adding the micromolecular red, blue, purple and yellow dyes, reacting for 6-12 hours at the temperature of 50-90 ℃, and adding an organic solvent to adjust the viscosity; cooling to 10-30 ℃, adding a salt forming agent, emulsifying at a high speed for 10-30 min, and adding deionized water for dispersing at a high speed for 10-30 min; and removing the organic solvent under the vacuum condition to obtain the cationic compound aqueous polyurethane-based high-molecular black dye emulsion. The invention utilizes the principle of three primary colors, and is prepared by connecting red, blue, purple and yellow dyes into a polyurethane chain through a compounding technology, thereby not only improving the blackness and utilization rate of the dyes, but also improving the dyeing performance and color fastness performance of the dyes. |
