A kind of method of wood modification

Abstract

The invention discloses a wood modification method. A wood is cut and dried, and is dipped in water solution of a composite loosening agent with a mass concentration of 20%; the loosened wood is put in a closed dipping tank; modifying agent water solution is added; the mass concentration of a modifying agent is 20-40%; the loosened wood is heated to reach 60-80 DEG C, is dipped by 10-20 hours, and is stood for cooling to reach the room temperature; the modifying liquid is discharged; the modifying liquid on the surface of the wood is cleaned; and the drying is performed. After the wood is cut for forming, the wood is dipped in the composite loosening agent; through adding of the composite loosening agent, bubbles can be generated in the wood dipping process; the bubbles can be used for dredging the internal of the wood, so that the modifying agent water solution can be preferably infiltrated inside in the later period; and then, through adding of the modifying agent water solution, the mechanical strength of the overall wood under long-time stress condition can be improved.

Description

technical field [0001] The invention relates to the field of wood processing, in particular to a method for wood modification. Background technique [0002] Wood is the lignified tissue of plants capable of secondary growth, such as trees and shrubs. After the primary growth of these plants ends, the vascular cambium in the rhizome becomes active, developing bast outward and wood inward. Wood is the general term for plant tissues that develop inwardly from the vascular cambium, including xylem and parenchyma rays. Wood plays a great supporting role in human life. According to the different properties and characteristics of wood, people use them in different ways. [0003] In the prior art, wood itself has good tensile strength and compressive strength, but under the action of long-term load, its own tensile strength and compressive strength will be lost, especially when it is exposed to sunlight for a long time. Can lead to increased strength loss. Contents of the inve...
