ABSTRACT:
A method for manufacturing hard kraft paper-made board block, wherein multiple layers of carton boards with large thickness are closely attached to one another by glue to form a thick board; and then multiple layers of three-layer corrugated boards having high strength and are made of A-class flock paper and kraft paper with high basic weight are attached in sequence to the thick board by glue, the multiple layers of three-layer corrugated boards forming an intermediate board; then another thick board and intermediate board are further attached to the first intermediate board; and finally an upmost layer of thick board is attached to the last intermediate board. Thereafter, the laminated board block is heated by high frequency and compressed and quickly dried and patterned to form a solid board block. Thereafter, a board with a preset width is cut away from the board block according to requirements. This board is horizontally placed together with the carton boards and the waved intercrossed ribs in the corrugated boards, the compression-resistance of the board exceeds 90% of that of the timber-made board. After coating the external surface of the board with thermo-melting glue, the hardness and compression-resistance thereof almost reach 100% of those of the timber-made board.
