| titleOfInvention | Water-based blocked polyisocyanate crosslinking agent and preparation method thereof |
| abstract | The invention discloses a water-based blocked polyisocyanate crosslinking agent shown in the following formula and a preparation method thereof. Firstly, diisocyanate reacts with alkyd compounds to prepare isocyanate-terminated linear polyurethane prepolymers, then a sealing agent reacts with the prepolymers to seal off partial active isocyanate groups, the sealed prepolymers react with an aqueous solution of vinylamine compounds, and finally ammonia water is used for neutralization to obtain the aqueous sealed polyisocyanate crosslinking agent. The preparation method can well avoid the serious gelation problem during the polymerization of the polyfunctional monomer, the water dispersibility and the compatibility of the obtained product with the water-based resin are both good, and the product has a good application prospect in the fields of wood lacquer, printing, leather and the like. |
