| titleOfInvention | Waterborne polyurethane emulsion for composite laser coating |
| abstract | The invention discloses waterborne polyurethane emulsion for a composite laser coating. The waterborne polyurethane emulsion is prepared by the following steps: performing vacuum dehydration on macromolecular polyhydric alcohol at the temperature of 120-130 DEG C for 1-1.5 hours, reducing the temperature to be 50-60 DEG C, adding diisocyanate and epoxy resin, raising the temperature to be 75-85 DEG C, and reacting for 2.5-3 hours; adding a hydrophilic chain extender and reacting for 1-2 hours; adding an alcohol chain extender and reacting for 2-3 hours, and adding acetone to reduce the viscosity during the period; adding a neutralizer, and carrying out a neutralization reaction at the temperature of 40-50 DEG C for 0.5-1 hour to obtain a neutralization product; adding the neutralization product into water in which an amine chain extender is dissolved, carrying out shearing emulsification at 30-40 DEG C for 0.5-2 hours while controlling the stirring speed to be 2000-4000rpm to obtain primary emulsion, and evaporating to remove acetone under reduced pressure to obtain the emulsion. The emulsion is a self-emulsified system and does not contain small molecular emulsifier, and an emulsifier migration phenomenon is avoided; the waterborne polyurethane emulsion is high in adhesive force with a base material, and interlayer separation is avoided; moreover, the waterborne polyurethane emulsion has high solvent resistance and paint film printability. |
