Abstract

La presente se refiere a un procedimiento para la fabricacion de materiales de enchapado de madera modificados. El procedimiento de acuerdo con la presente comprende los siguientes pasos: i) impregnar un enchapado de madera no modificado con una composicion endurecible acuosa, la cual: a) presenta por lo menos un compuesto de urea H reticulable, el cual presenta por lo menos un grupo N- ligado de formula CH2OR, en donde R significa H o alquilo C1-4, y/o un grupo 1,2-bishidroxietan-1,2-diilo que forma puente con los dos N de la urea, y b) contiene por lo menos una substancia catalizadora del reticulado; ii) prensar el enchapado de madera impregnado a temperatura elevada; iii) encolar el enchapado de madera obtenido en el paso ii) y/o el soporte, y iv) pegar en forma plana el enchapado de madera encolado con un soporte u otras láminas de enchapado para formar el material de enchapado de madera.
