| titleOfInvention | Quick-drying waterborne polyurethane ink binder and preparation method thereof |
| abstract | The invention discloses a quick-drying water-based polyurethane ink binder and a preparation method thereof, wherein polyester diol and polyether diol are subjected to vacuum dehydration for 1 hour at 120 ℃, are cooled to 50 ℃ after dehydration, are added with isocyanate, are heated to 85 ℃, are subjected to heat preservation for 2 hours, are added with hydrophilic chain extender, and are kept at 85 ℃ for further heat preservation for 2 hours to obtain a prepolymer; cooling the prepolymer to 50 ℃, adding butanone, and stirring for 30 minutes to obtain a diluted prepolymer; pouring the prepolymer into a dispersion machine, cooling to below 40 ℃, adding a neutralizing agent, and stirring in the dispersion machine to form salt for 30 minutes; after salifying, adding deionized water, adding a rear chain extender after the prepolymer is dispersed, and continuing dispersing for 30 minutes to obtain a polyurethane dispersion liquid; the quick-drying water-based polyurethane ink binder is prepared by removing ketone from the polyurethane dispersion liquid at 45-55 ℃ and under the pressure of-0.08 MPa, and has the advantages of high drying speed, good film forming property, no organic solvent and environmental friendliness. |
