Title:
MANUFACTURE OF DECORATIVE PLATE
Document Type and Number:
Japanese Patent JP3836239
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To suppress occurrence of an interlayer release by splitting a woody fiber plate having a thickness and a specific gravity of specific ranges and a larger densities of front and rear surfaces than that of a core layer into two parts from a center of a thickness direction, adhering the low density layer side disposed at a front direction to a surface of a woody base plate to make a composite plate, grinding a surface of the low density layer, and then coating it with a synthetic resin liquid to impregnate it thereinto.
SOLUTION: A woody fiber late having a thickness of 2.5 to 4 mm, a specific gravity of 0.6 to 1.0 and densities of front and rear layers larger than that of a core layer is split from a center in a thickness direction by a cutter blade 4, and forming a high density layer at one surface side and a low density layer at the other surface side to a woody fiber plate material 2. Then, with the low density layer side disposed at a front direction, adhered to the surface of a base plate 1 with an adhesive 3 to form a composite plate A1. Then, the low density layer surface of the material 2 is ground. Then, the surface of the material 2 of the plate A1 is coated and impregnated with a synthetic resin liquid 5 by an impregnating roll 6. Thus, the front layer of the material 2 is strengthened, and a corner cutout or an interlayer release can be suppressed.
