| titleOfInvention | Polyisocyanates for lacquers, process for their production and their use in thermosetting two-component polyurethane lacquers |
| abstract | a) an freien Isocyanatgruppen von 0 bis 8 Gew.-%, b) an blockierten Isocyanatgruppen von 10 bis 28 Gew.- % und c) an Struktureinheiten der Formel -NH-NH-CO-O-von 2 bis 10 Gew.-% gekennzeichnet sind, ein Verfahren zur Herstellung derartiger Polyisocyanate, bei weichem man 10 bis 30 Moi-% der Isocyanatgruppen eines organischen Polyisocyanats mit alkoholischen Hydroxylgruppen und Struktureinheiten der Formel -O-CO-NH-NH-CO-O- und/ oder der Formel H 2 N-NH-CO-O- aufweisenden Umsetzungsprodukten von 1 Moi Hydrazin mit 1-2 Mol eines cyclischen Carbonats zur Reaktion bringt und 50-90 Mol-% der Isocyanatgruppen des Ausgangspolyisocyanats mit Blokkierungsmitteln blockiert, wobei die genannten Umsetzungen in beliebiger Reihenfolge oder gleichzeitig erfolgen können, sowie die Verwendung der neuen Lackpolyisocyanate als Isocyanat-Komponente in Hitze härtbaren Zweikomponenten-Polyurethanlacken. The invention relates to lacquer polyisocyanates which have a content, based on the weight, without including the weight of the blocking agent, a) 0 to 8% by weight of free isocyanate groups, b) on blocked isocyanate groups of 10 to 28% by weight and c) on structural units of the formula -NH-NH-CO-O- are characterized from 2 to 10% by weight, a process for the preparation of such polyisocyanates in which 10 to 30 mol% of the isocyanate groups of an organic polyisocyanate with alcoholic hydroxyl groups are used and structural units of the formula -O-CO-NH-NH-CO-O- and / or the formula H 2 N-NH-CO-O- having reaction products of 1 moi hydrazine with 1-2 mol of a cyclic carbonate and 50-90 mol% of the isocyanate groups of the starting polyisocyanate are blocked with blocking agents, the reactions mentioned being able to take place in any order or simultaneously, and the use of the new coating polyisocyanates as isocyanate components in heat-curable two-component polyurethane coatings. |
