Abstract

Procedimiento para la preparación de pegamentos elásticos que se endurecen sin burbujas ni ampollas en presencia de la humedad del aire, a base de poliuretanos para uniones por encolado elásticas, altamente resistentes mecánicamente, caracterizado porque mezclan intensamente entre sí con exclusión de la humedad, masas estables en ausencia de la humedad, que consisten en a) productos de reacción por adición de polialcohilenglicoles ramificados con pesos moleculares medios de 200 a 10.000, preferiblemente de 400 a 6000, y diisocianatos, y de b) 1. productos de reacción de aminas secundarias cíclicas con aldehidos alifáticos o cetonas cíclicas o 2. productos de reacción de alpha) aminas secundarias cíclicas, que aparte del grupo amino secundario tienen otro grupo que reacciona con isocianatos -especialmente un grupo hidroxilo-, con aldehidos alifáticos o cetonas cíclicas y de reacción adicional con beta) triisocianatos y diisocianatos alifáticos o cicloalifáticos apropiados, especialmente isocianatos polímeros previos según a), y eventualmente de c) materiales de carga, plastificantes, pigmentos e inductores de adherencia usuales, que son anhidros o cuyo contenido de agua es muy pequeño.
