| titleOfInvention | A kind of water-based polymer polyurethane dispersant and preparation method thereof |
| abstract | The invention relates to the technical field of fine chemical additives, in particular to an aqueous polymer polyurethane dispersant and a preparation method thereof. By introducing styrenated phenol into the molecular structure, the present invention generates a more polyvalent aromatic structure, has better wetting and dispersing properties for organic pigments, reduces the viscosity of the system more effectively, and at the same time makes aromatic hydrocarbon isocyanate and alkyl-terminated mono The reaction between hydroxyl polyoxyethylene ether and monohydroxy tertiary amine introduces pigment anchoring groups such as polyoxyethylene ether and tertiary amine into the molecular structure, so that the dispersant has excellent wetting and dispersing effect on carbon black. The water solubility is adjusted by introducing alkyl polyoxyethylene ether, avoiding the introduction of strong hydrophilic carboxylate ions, thereby enhancing the water resistance and salt spray resistance of the paint film. Use of organometallic catalysts. The dispersant of the invention does not contain organic solvents and organic metals, has wide versatility and high performance, and is an environment-friendly polymer dispersant. |
