| titleOfInvention | Branched polyurethane thickener with ionized linear main chain and preparation method thereof |
| abstract | The invention relates to an associated polyurethane thickener used in the processing fields of water-based paint, textile printing, water-based resin coating and the like, in particular to a branched polyurethane thickener with an ionized linear main chain and a preparation method thereof. The method comprises the following steps: preparing raw materials; active prepolymerization; active end capping; graft modification; and (5) finishing. In the invention, the molecular structure of the thickening agent has a longer main chain structure and 4 polyether branches, and long-chain alkyl is introduced into the lateral part and the tail part of the molecular structure; meanwhile, the main chain structure of the polymer has anionic property or cationic property. The thickening capability of the thickening agent is stronger due to the larger main chain structure and the lateral hydrophobic association structure thereof, and the using amount is less; the anionic group enables the thickening agent to be easier to emulsify and disperse, and the thickening speed is higher; the cationic group enables the thickening agent to have certain reverse electrolyte performance and better salt resistance; the 'remote claw type' hydrophobic association structure on a plurality of branched chains enables the intermolecular association and the thickening capacity of dilute solution to be stronger. |
