The invention relates to the technical field of textile coatings, and discloses a self-repairing polyurethane emulsion. The self-repairing polyurethane is a hydrophilic base block polyurethane composed of a stationary phase and a reversible phase, and has a molecular weight of 10,000 to 50,000, wherein the stationary phase has a temperature higher than 100 ° C. The glass transition temperature or the crystallization melting temperature; the reversible phase has a deformation recovery temperature of -10 ° C to 60 ° C.
The polyurethane emulsion can be made into a textile printing coating, the self-repairing of the printing coating is ≤5mm, the deformation fixing rate is ≤30%, the deformation recovery rate is ≥90%, and the deformation recovery temperature of the reversible phase is -10°C to 60°C.
