Abstract
Se describe un procedimiento para la produccion de espumas duras de poliuretano a partir de polioles y poliisocianatos, caracterizado porque la espuma dura de poliuretano se obtiene mediante transformacion de A) Un componente poliol que exhibe un promedio mínimo de dos átomos de hidrogeno reactivos frente a isocianato, que contiene 1. a) Del 20 al 80% en peso de un producto de adicion, con un índice de OHG de al menos 500, de di- o poliaminas que exhiben grupos amino primarios y/o secundarios con oxidos de alquileno. b) Del 80 al 20% en peos de aceite de ricino, y/o c) Productos de transformacion que se obtienen mediante reaccion de los productos de adicion mencionados en la) con aceite de ricino. 2. Dado el caso, otros compuestos que exhiben al menos dos átomos de hidrogeno reactivos frente a isocianato como poliéterpolioles o poliésterpolioles, así como 3. Dado el caso, agentes expansores, 4. Agua, 5. Catalizadores y 6. Dado el caso, sustancias coadyuvantes y aditivos con B) Un poliisocianato con un contenido en NCO del 20 al 48% en peso.
