Abstract

Los poliuretanos que tienen curacion mejorada se preparan haciendo reaccionar a) diisocianatos y/o poliisocianatos orgánicos y/o orgánicos modificados, con b) polioles de poliéter basados en aminas aromáticas, capaces de prepararse haciendo reaccionar combinaciones de amina específicas y, si se desea, co-iniciadores adicionales en una adicion molecular por etapas de oxido de alquileno, y también, si se desea, compuestos de peso molecular relativamente elevado adicionales que contienen por lo menos dos átomos de hidrogeno reactivos, y, si de desea, c) diluyentes y/o reticuladores de cadena de bajo peso molecular, en presencia de d) agentes hinchadores, e) catalizadores y, si se desea, f) auxiliares y/o aditivos adicionales, en donde la combinacion de amina específica usada en una mezcla de aminas de la serie de difenilmetano que consiste de 5 por ciento a 20 por ciento en peso de amina de 4 anillos, de 15 por ciento a 30 por ciento en peso de amina de 3 anillos, de 20 por ciento a 35 por ciento en peso de aminas que tienen más de 4 anillos y de 25 por ciento a 50 por ciento en peso de amina de 2 anillos, en donde las proporciones se suman hasta 100 por ciento en peso, en combinacion con aminas aromáticas adicionales.
