Problems solved by technology

At present, in order to enhance the flame retardant and fireproof performance of solid wood panels, carbonization treatment tends to be carried out on them. However, due to the high carbonization temperature of solid wood panels, the mechanical strength and insulation performance of solid wood panels will be greatly lost. At the same time, there are Large internal stress leads to defects such as internal cracking of the plate and easy peeling off between the structural layers
Therefore, the current plate carbonization process lacks a groundbreaking optimization for the internal stress relief inside the plate.

Abstract

The invention discloses a preparation process of a laminated solid wood board, which comprises the following steps: performing one-step polishing treatment on a log board, and performing carbonization treatment to obtain a board A; after dipping maintenance treatment is completed on the plate A, second-step polishing treatment is conducted, and a plate B is obtained; after the board B is coated with an insulating layer, one-step hot pressing treatment is conducted to obtain a board C; after the board C is coated with a waterproof layer, two-step hot pressing treatment is conducted, and a board D is obtained; after veneers are attached in the wood grain direction of the plate D, one-step cold pressing treatment is conducted, and a plate E is obtained; after painting and transfer printing are conducted on the board E, two-step cold pressing treatment and three-step polishing treatment are conducted, and a laminated solid wood board is obtained; a laminated solid board is also disclosed. A specific process system is disclosed, the problem that the comprehensive performance of a conventional laminated solid wood board is affected due to large residual internal stress is solved, in the whole preparation process, the water content of the board is strictly controlled, the internal residual stress of the board is eliminated, the defects of warping, internal cracking and the like of the board are overcome, and the product quality of the board is further improved.

Description

technical field [0001] The invention relates to the technical field of wood board processing, in particular to a laminated solid wood board and a preparation process thereof. Background technique [0002] Solid wood boards are made of raw wood boards. Due to their poor hardness, external force resistance, water resistance, flame retardancy and fire resistance, solid wood boards need to be further processed to meet the use requirements. At present, in order to enhance the flame retardant and fireproof performance of solid wood panels, carbonization treatment tends to be carried out on them. However, due to the high carbonization temperature of solid wood panels, the mechanical strength and insulation performance of solid wood panels will be greatly lost. At the same time, there are The large internal stress leads to defects such as internal cracks in the board and easy peeling off between the structural layers. Therefore, the plate carbonization process at this stage lacks a...
