Problems solved by technology

[0002] Log boards are not corrosion-resistant, easily deformed, and have poor waterproof and fireproof performance, which needs further improvement
Chinese Patent No. "CN1375387A, Gelatinized Wood and Its Manufacturing Method" discloses a method for improving the performance of the board, which is to mix the wooden substrate with glue, and the glue penetrates into the fiber gaps of the wooden substrate, thereby improving the quality of the wood. The waterproof and fireproof performance of the substrate, but the composition of the glue is not disclosed
The performance of different glues varies greatly. Some glues will seep into the board too quickly, resulting in uneven distribution of glue in the board and uneven product quality. Some glues contain non-environmental protection materials, which are prone to pollution. The performance of the glue is not comprehensive, and it cannot improve the performance of the board in many aspects

Abstract

The invention belongs to the technical field of wood treatment, and discloses a waterproof, anticorrosive and deformation-proof wood new material plate, which is prepared according to the following steps: a single-layer log plate with a thickness of 8-18 mm is obtained by rotary cutting by a rotary cutting machine, the single-layer log plate and glue are placed in a pressure vessel, the pressure vessel is closed, pressurization is carried out, then the pressure vessel is opened, the plate is taken out, and natural air drying is carried out to obtain the waterproof, anticorrosive and deformation-proof wood new material plate. The glue permeates into log wood through pressure so as to improve the comprehensive performance of the wood.

Description

technical field [0001] The invention belongs to the technical field of wood treatment, in particular to a waterproof, anti-corrosion and anti-deformation wood new material board. Background technique [0002] Log boards are not corrosion-resistant, easily deformed, and have poor waterproof and fireproof performance, which needs further improvement. Chinese Patent No. "CN1375387A, Gelatinized Wood and Its Manufacturing Method" discloses a method for improving the performance of the board, which is to mix the wooden substrate with glue, and the glue penetrates into the fiber gaps of the wooden substrate, thereby improving the quality of the wood. The waterproof and fireproof properties of the substrate, but the composition of the glue is not disclosed. The performance of different glues varies greatly. Some glues will seep into the board too quickly, resulting in uneven distribution of glue in the board and uneven product quality. Some glues contain non-environmental protecti...
