Title:
MANUFACTURING METHOD OF LAMINATED WOOD
Document Type and Number:
Japanese Patent JP2021059110
Kind Code:
A
Abstract:
To improve wettability of an aqueous adhesive coated on one surface of a lamina to a bonding surface of another lamina, thereby enhancing the adhesion property of the aqueous adhesive.SOLUTION: There is provided a manufacturing method of laminated wood 10, the method comprising an adhesive coating step of coating an aqueous adhesive 12 on respective surfaces on one side of a plurality of laminae 11 excluding an uppermost stage or lowermost stage lamina 11 among the plurality of laminae 11; and a laminating/clamping step of laminating/clamping the plurality of laminae 11 to manufacture the laminated wood in such a manner that a surface on which the aqueous adhesive 12 of a lamina 11 is coated, and another surface on which no aqueous adhesive 12 of the other lamina 11 is coated come into contact with each other. The method further comprises a water coating step of coating water 13 in a coating amount of 5 g/m2 to 25 g/m2 on other surfaces of the plurality of laminae 11 excluding a lowermost stage or uppermost stage lamina 11 among the plurality of laminae 11 before the adhesive coating step, or between the adhesive coating step and the laminating/clamping step.SELECTED DRAWING: Figure 1
