Embodiment 1

[0017] Example 1 A preparation method of variable color water-based veneer, comprising the following steps:

[0018] (1) Set the weight to 50g / m at a speed of 10m / min 2 The wood fiber paper is impregnated with water-based polyurethane, the excess water-based polyurethane is squeezed out with a pressure of 0.1MPa, and dried at a temperature of 80°C until the moisture content is 3%, and wood fiber paper impregnated with water-based polyurethane is obtained. .

[0019] Among them: the solid content of water-based polyurethane is 20%, and the viscosity of 4 cups is 10s.

[0020] ⑵Adopt the method of printing or transfer film transfer, print the wood grain pattern on the wood fiber paper impregnated with water-based polyurethane, and obtain the fiber paper with wood grain.

[0021] (3) Add the water-based resin with color-changing material at 200g / m 2 The dosage is coated on the wood grain surface of the fiber paper with wood grain, so that the color of the veneer changes when ...

Abstract

The invention relates to a preparation method of a color-variable waterborne wood veneer. The method includes the following steps that firstly, wood fiber paper is subjected to impregnation treatment through waterborne polyurethane, remaining waterborne polyurethane is extruded out and dried till the water content is 3-13%, and wood fiber paper dipped with waterborne polyurethane is obtained; secondly, through a printing method or a transferring method of a transfer membrane, wood grain patterns are printed on the wood fiber paper dipped with waterborne polyurethane, and the fiber paper with wood grains is obtained; and thirdly, the wood grain surface of the fiber paper with the wood grains is coated with waterborne polyurethane where color-variable materials are added, and then the color-variable waterborne wood veneer can be obtained. The preparation method is simple in technology and easy to implement, the obtained color-variable waterborne wood veneer is good in performance and can be widely used for decorative materials, the color of furniture changes when traditional furniture materials change along with the environment, and the color-variable waterborne wood veneer is environment-friendly and free of pollution.

Description

technical field [0001] The invention relates to the field of decorative materials, in particular to a method for preparing a color-changing water-based veneer. Background technique [0002] With the rapid development of the economy, people have higher and higher requirements for decorative materials, not only the pursuit of beautiful color, environmental protection and pollution-free, but also more and more common requirements for intelligence, such as color or pattern Varies with temperature, humidity, light, etc. [0003] Ordinary veneer uses organic solvent-based paint, which will release formaldehyde, etc., which will cause harm to the body and pollute the environment, which can no longer meet the needs of customers. Therefore, research and development of formaldehyde-free and environmentally friendly water-based veneer, and the perfect combination of light, temperature, humidity and other discoloration technologies are the inevitable trend of its development.
