Abstract

PROCEDIMIENTO DE OBTENCION DE CUERPOS MOLDEADOS REFORZADOS CON FIBRAS. SE RALIZA UNA REACCION EN CADEN A UNA TEMPERATURA DE 10 A 50 GC. SE PREPARA UNA MEZCLA DE UN POLISOCIANATO CON UN PUNTO DE FUSION SUPERIOR A LA TEMPERATURA DE REACCION, CON UN POLISOCIANATO LIQUIDO A ESTA TEMPERATURA. ESTA MEZCLA SE HACE REACCIONAR CON UNO O VARIOS COMPUESTOS CONTENIENDO DE 2 A 8 GRUPOS HIDROXILO, DE ALTO PESO MOLECULAR Y UN AGENTE PROLONGADOR DE CADENA CONTENIENDO DE 2 A 4 GRUPOS HIDROXILO. SE PUEDE AÑADIR EN ESTA ETAPA UN COMPUESTO CON 2 A 4 GRUPOS AMINO O AGUA, UN TAMIZ MOLECULAR DE TIPO SILICATO ALUMINIO SODICO Y UNO O VARIOS ACTIVADORES DE FORMA ESCALONADA. TODOS ESTOS COMPONENTES AÑADIDOS A LA PRIMERA MEZCLA SON LIQUIDOS A LA TEMPERATURA DE REACCION. DURANTE LA REACCION DE POLIADICION QUE SIGUE SE AÑADE UN MATERIAL FIBROSO COMO FIBRAS DE VIDRIO. ESTA MASA DE MOLDEO SE DEJA CRECER EN VISCOSIDAD Y POSTERIORMENTE SE MOLDEA Y ENDURECE BAJO PRESION. 8
