Abstract

Procedimiento para la preparación de un material ligero mal conductor del calor, resistente al fuego y teniendo características mecánicas muy elevadas, caracterizado en lo que comprende las etapas siguientes: A.- Mezclar una resina fenólica líquida, del tipo "resol" con un material inerte, en un porcentaje de resina de 100% a 30% (material inerte presente de 0 a 3 veces la cantidad de resina). B.- Añadir a la mezcla de 1% a 6% en peso un agente endurecedor, con relación al peso de dicha resina fenólica. C.- Mezclar la mezcla obtenida en B, en un turbo-mezclador durante un tiempo de 15 a 20 segundos. D.- Colar la mezcla obtenida en C, en un cajón o un molde cerrado, provisto de aire libre, resistiendo a una presión interna que pueda alcanzar 2 Kg/cm2, y teniendo un volumen igual a 1 a 2 veces el volumen de la mezcla a endurecer. E.- Dejar reposar este molde ya lleno a temperatura y presión ambiente durante un periodo de 0,5 a 10 minutos. F.- Introducir el dicho molde en un ambiente de 80/100ºC durante un periodo de 15 a 25 minutos. G.- Extraer el objeto endurecido del molde y dejarlo estar en un ambiente a 80/100ºC, durante un periodo de 45 a 90 minutos. H.- Extraer el dicho objeto endurecido del dicho ambiente.
