Abstract

Procedimiento para preparar un género moldeado soportado con espuma de poliuretano, caracterizado porque comprende las etapas de: (A) aplicar una mezcla espumable o espuma de componentes de reacción de poliuretano a la parte posterior de un género, comprendiendo dichos componentes de reacción: (1) un poliisocianato; (2) un compuesto orgánico que contiene al menos dos átomos de hidrógeno capaces de reaccionar con los grupos isocianato, que tiene un peso molecular comprendido entre 400 y 16.000 y que no contiene esencialmente grupo etilénicamente insaturados; (3) ésteres hidroxílicos de ácidos acrílico y alquil-acrílico; (4) un iniciador de radicales libres; (5) un catalizador activado por calor para la reacción entre los componentes (1) y (2); (6) un agente expansionante o un gas inerte para el espumado; (7) un agente de superficie activa para proporcionar estabilidad a la espuma; (B) calentar el género revestido durante un periodo de 15 segundos a 10 minutos a una temperatura comprendida entre 27 a 121ºC aproximadamente, para permitir que proceda la reacción de poliuretano para producir una espuma de poliuretano gelificada y libre de adherencia; y (C)) conformar y curar el género soportado con espuma resultante mediante un proceso de moldeo en caliente.
