Problems solved by technology

Most of the traditional wood finishing methods add dyes to the paint, which reduces the clarity of the wood texture, the color of the wood itself is distorted, and the natural texture is also covered. The color is too consistent, and the naturalness of the wood is also greatly reduced.

Abstract

The invention discloses a wood surface chemical color changing method. According to the wood surface chemical color changing method, the surface of wood is coated with copper chloride solution first,after drying, the surface of the wood is coated with a color changing agent, drying is conducted again, color changing of the wood is completed, and a finished product is obtained. The wood surface chemical color changing method has superior permeability, bonding strength of the color changing solution and the wood is higher, loss resistance is better, thus the color presented by the product madethrough the wood surface chemical color changing method is richer, lines are clearer, the layered feeling is higher, the color changing method is simple to operate, and the processing process is moreenvironmentally friendly.

Description

technical field [0001] The invention relates to a wood surface chemical discoloration method, 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 texture, distorts the color of th...
