Abstract
La presente se refiere a la fabricacion de dispersiones reticulantes de PUR acuosas exentas de disolvente o pobres en disolvente estables al almacenamiento con grupos isocianato bloqueados con pirazol, a agentes de recubrimiento fabricados a partir de ellas y a su uso en recubrimientos. Reivindicacion 1: Procedimiento para la fabricacion de dispersiones de prepolímeros de poliuretano bloqueado, caracterizado porque 1) en primer lugar se fabrica un prepolímero de poliuretano bloqueado mediante la reaccion de a) 100% en equivalentes de al menos un poliisocianato con b) 50 a 90% en equivalentes respecto a los grupos reactivos con isocianato de un agente bloqueante térmicamente disociable, c) 5 a 45% en equivalentes respecto a los grupos reactivos con isocianato de un ácido monohidroxicarboxílico como agente hidrofilizante, y d) 0 a 25% en equivalentes respecto a los grupos reactivos con isocianato de un ácido polihidroxicarboxílico como agente hidrofilizante, y e) 0 a 15% en equivalentes respecto a los grupos reactivos con isocianato de un componente alargador de cadena, al menos di- o polifuncional respecto a los grupos reactivos con isocianato, con un peso molecular de 32 a 350 g/mol, en el que i) se realiza éste usando disolventes orgánicos (parcialmente) miscibles con agua inertes frente a grupos NCO con puntos de ebullicion inferiores a 120°C (a 101,3 kPa), ii) y se usan éstos en una cantidad tal que el prepolímero de poliuretano contenido en la disolucion de reaccion, después de completada la reaccion, se presente en una cantidad de 70 a 98% en peso, II) se dispersa en agua la disolucion de prepolímero de poliuretano obtenida en la etapa (1), en la que antes, durante o después de dispersar se realiza una desprotonacion al menos parcial de los grupos ácido carboxílico con una base, y después III) se elimina completamente por destilacion el disolvente orgánico contenido, dado el caso también paralelamente a la dispersion.
