| titleOfInvention | Waterborne polyurethane resin for toluene-reduced superfine fiber base and preparation method and application thereof |
| abstract | The invention relates to waterborne polyurethane resin for toluene-reduced superfine fiber base and a preparation method and application thereof, wherein the waterborne polyurethane resin is prepared by the following method: stirring polyester polyol, polyether polyol and diisocyanate at the temperature of 65-95 ℃ for reaction for 1-3 hours, and then sequentially adding a diol chain extender and a carboxylic acid hydrophilic chain extender to perform chain extension reaction respectively to obtain a prepolymer; and (2) cooling the prepolymer to be less than or equal to 60 ℃, adding a low-boiling-point solvent, uniformly stirring, adding a neutralizing reagent, stirring for 0.5-2 h, cooling to be less than or equal to 40 ℃, adding water for emulsification, adding a sulfonic acid type hydrophilic chain extender and a diamine type chain extender sequentially for chain extension respectively after emulsification is finished, heating to be more than or equal to 70 ℃ after the emulsification is finished, removing the solvent in vacuum, cooling, and discharging to obtain the waterborne polyurethane resin. The resin is used for preparing the toluene-reduced superfine fiber Bass, and the obtained Bass has high thickness retention rate, soft and plump hand feeling, good elasticity, high tensile strength and good tear resistance. |
