Title
(EN) MODIFIED POLYISOCYANATE
(FR) POLYISOCYANATE MODIFIÉ
Abstract
(EN)
The present invention relates to a modified polyisocyanate and use thereof, in particular as a crosslinking component of water-soluble or water-dispersible coatings. The modified polyisocyanate is obtained by a reaction of a system comprising the following components: at least an aminosulfonic acid; at least a polyisocyanate; at least a tertiary amine; and optionally a polyether alcohol containing an ethylene oxide group. The modified polyisocyanate comprises at least an iminooxadiazinedione structure and at least an isocyanurate structure, the weight ratio of the iminooxadiazinedione structure to the isocyanurate structure being 1:300 to 1:5. The amount of sulfonate group of the modified polyisocyanate is 0.75% by weight to 1.1% by weight, based on the amount of the modified polyisocyanate as 100% by weight. The viscosity thereof is 500 mPa·s to 10000 mPa·s, as determined according to DIN EN ISO 3219:1994-10 at a temperature of 23°C and a shear rate of 10 s-1. The coating comprising the modified polyisocyanate of the present invention can be manually stirred well, and the resulting coating layer has high gloss and good transparency.
(FR)
La présente invention concerne un polyisocyanate modifié et son utilisation, en particulier en tant que composant de réticulation de revêtements solubles dans l'eau ou dispersibles dans l'eau. Le polyisocyanate modifié est obtenu par une réaction d'un système comprenant les composants suivants : au moins un acide aminosulfonique ; au moins un polyisocyanate ; au moins une amine tertiaire ; et éventuellement un polyéther alcool contenant un groupe oxyde d'éthylène. Le polyisocyanate modifié comprend au moins une structure d'iminooxadiazinedione et au moins une structure d'isocyanurate, le rapport en poids de la structure d'iminooxadiazinedione à la structure d'isocyanurate étant de 1:300 à 1:5. La quantité de groupe sulfonate du polyisocyanate modifié est de 0,75 % en poids à 1,1 % en poids, sur la base de la quantité du polyisocyanate modifié en tant que 100 % en poids. Sa viscosité est de 500 mPa s à 10 000 mPa s, telle que déterminée selon la norme DIN EN ISO 3219:1994-10 à une température de 23 °C et un taux de cisaillement de 10 s-1. Le revêtement comprenant le polyisocyanate modifié de la présente invention peut être bien agité manuellement, et la couche de revêtement résultante a un brillant élevé et une bonne transparence.
