Abstract

Procedimiento para la obtención de materiales espumados de poliisocianurato termo-conformables por reacción de compuestos que llevan grupos hidroxilo con un exceso de poliisocianatos en presencia de catalizadores de trimerización de isocianato, agentes de propulsión y, en caso dado, ulteriores agentes auxiliares para la espumación, caracterizado porque como poliisocianato se emplea un polimetilenpolifenilpoliisocianato, que contiene como mínimo un 80% en peso de diisocianatodifenilmetano y porque como compuestos que llevan grupos hidroxilo se emplean: a) poliéteres, que llevan como mínimo un grupo hidroxilo, del índice OH 26 - 112, cuya proporción en óxido alquilénico se compone en como mínimo un 20% en peso, preferentemente un 30 a 50% en peso de restos de óxido etilénico y b) dialcoholes con un peso molecular de 62 hasta 200, empleándose el poliéter, que contiene como mínimo un grupo hidroxilo, en una cantidad de 0,015 hasta 0,04 equivalentes de OH y los dialcoholes en una cantidad de 0,2hasta 0,4 equivalentes de OH por equivalente de NCO.
