| titleOfInvention | Environment-friendly water-oil universal polyurethane dispersant and preparation method thereof |
| abstract | The invention discloses an environment-friendly water-oil universal polyurethane dispersant and a preparation method thereof. The invention carries out catalytic reaction on isocyanate to obtain a polymer of the isocyanate, then carries out chain extension on polyether polyol and the isocyanate after reaction, and further carries out reaction with the obtained polymer of the isocyanate to obtain the water-oil universal polyurethane dispersant. The synthesized polyurethane dispersant has a special structure and has anchor groups, and the polyurethane dispersant can disperse and wrap pigments and can grasp other resin groups to form a stable dispersed phase by using the stable dispersoid of the anchor groups. The polyurethane dispersant also has the remarkable characteristics of good compatibility, good color development, good flexibility and wide universality, and has excellent compatibility and dispersion effect in a water-oil system. In addition, the polyurethane dispersant is not added with an organic solvent in the preparation process, and is not added with an organic solvent in the storage and use processes, and the VOC is zero, so that the polyurethane dispersant is environment-friendly and efficient. |
