Abstract
METODO PARA LA PREPARACION DE ARTICULOS COMPUESTOS LIGNOCELULOSICOS, TALES COMO TABLEROS DE PARTICULAS DE MADERA. SE MEZCLAN PARTICULAS LIGNOCELULOSICAS, COMO VIRUTAS O FIBRAS DE MADERA, CON UN 1,5 A 12% EN PESO, EN RELACION A LAS PARTICULAS LIGNOCELULOSICAS SECADAS AL HORNO, DE UNA COMPOSICION AGLOMERANTE ADHESIVA FORMADA POR UN 40-60% EN PESO DE DI- Y POLIISOCIANATO ORGANICO, TAL COMO UN DIFENILMETAM- DIISOCIANATO, Y UN 60-40% EN PESO DE OXIDO DE ALQUILENO O ALQUILENO HALOGENADO DE C W, TAL COMO OXIDO DE PROPILENO. SE AÑADE UN 20-35% EN PESO DE LIGNINA COMO DILUYENTE, OBTENIENDOSE UNA COMPOSICION MOLDEABLE. SE INTRODUCE EST EN UN MOLDE, PLACA O CHAPA METALICA RECUBIERTO CON UN AGENTE DE LIBERACION, TAL COMO UN JABON METALICO. SE CONFORMA MEDIANTE COMPRESION A UNA TEMPERATURA DE 140-200<025>C, A UNA PRESION DE 7-42 KG/CM , DURANTE DE 1 A 10 MINUTOS. SE LIBERA DEL MOLDE EL ARTICULO COMPUESTO ASI OBTENIDO.
