Method for inducing wood discoloration by using chemical color-changing agent

Abstract

The invention discloses a method for inducing wood discoloration by using a chemical color-changing agent. The method comprises the following steps that firstly, a precursor substance solution is coated on the surface of wood, then the surface of the wood is coated with the color-changing agent after drying, and drying is carried out again to complete the color change of the wood to obtain a finished product. According to the method, the color saturation after chemical color change of the wood can be improved, so that the color of the wood is more easy to display after the wood is subjected tothe color change, the excellent permeability performance is achieved, the bonding strength of the wood color-changing layer is higher, the loss resistance is better, moreover, the displayed color isnatural and beautiful, the texture is clearer, the layering sense is stronger, and the color is richer.

Description

technical field

[0001] The invention relates to a method for inducing wood discoloration by a chemical discoloration agent, which belongs to the field of wood production. Background technique

[0002] In recent years, my country's demand for wood resources, especially natural precious wood, has been increasing. However, my country's own wood resources have been continuously reduced and a large amount of imports are needed. my country's wood resources are seriously scarce, especially natural precious hard broad-leaved wood. In order to increase the economic value-added of wood as much as possible, it has become the main trend of development to use wood veneer to decorate the surface of wood products on a large scale. Wood has very good mechanical properties and decorative properties. During use, the surface modification of wood is an essential process in the use of wood. Most of the traditional wood finishing methods add dye to the paint, which reduces the clarity of wood tex...
