Manufacturing method of finger joint laminated board with surface concave-convex three-dimensional embossment effect

The invention discloses a manufacturing method of a finger joint laminated board with a surface concave-convex three-dimensional embossment effect. The manufacturing method comprises the following steps: A. material preparing; B. tenoning; C. lengthwise and widthwise splicing; D. sanding and edge cutting on a board blank, wherein the board blank is subjected to double-side sanding and fine sanding to reach required flatness; E, carbonizing treatment; F. compression molding treatment. The manufacturing method provided by the invention is simple in technology; the finger joint laminated board manufactured according to the manufacturing method has high structural strength, good stability and low adhesive consumption and is free from the quality problem that steps and surface bulges are formed at joints.
