Method for manufacturing high-density wood laminate material
This method for manufacturing a high-density strand board enables high-density strand boards to be formed by using about the same press pressure as press pressures required to form strand boards with common densities, so that the high-density strand boards can be produced without using special facilities and equipment. A pretreatment process P2 is performed on strands 5 before pressing. The pretreatment process P2 is comprised of a first treatment process P2a and a subsequent second treatment process P2b. At least one of beating, high-frequency treatment, high-temperature high-pressure treatment, high-water pressure treatment, repeated deaeration and dehydration treatment, and chemical treatment is performed in the first treatment process P2a, and roll pressing or flat press pressing is performed in the second treatment process P2b. A strand board B with a density of 750 to 950 kg/m.sup.3 is formed by using a press pressure of 4 N/mm.sup.2 or less.
