Embodiment Construction

[0023] A method for preparing a wall decoration board, characterized in that it comprises the following steps:

[0024] 1) Wood base material preparation

[0025] Sawdust is dried to a moisture content of 10-15%. Sawdust, ethanol, and NaOH are mixed in a mass ratio of 1:1.1-1.8:0.1-0.3 and placed in a reactor, stirred and heated to 180-200 under a pressure of 2.0-3.5MPa. ℃, react for 3-6h, part of the lignin in the sawdust is dissolved in the solution, let stand to cool to room temperature, add HCl to neutralize all NaOH, dry at 80-90℃ for 1-2h, anaerobic condition Heating to 180-230°C under low temperature, and keeping it warm for 100-120h, to partially decompose the cellulose in the sawdust and form a reddish-brown woody base material;

[0026] 2) Preparation of support matrix

[0027] Take part of the wood base material, mix and stir the wood base material and water at a ratio of 100; After completion, add it to the molding machine for molding. The shape of the molding i...

Abstract

The invention discloses a preparation method of a wall surface decoration plate. The preparation method includes the following steps of (1) preparation of a wood base material, (2) preparation of a supporting base body, (3) preparation of a functional material, (4) compounding and (5) surface treatment. According to the method, lignin is used as an adhesive, and chemically-synthesized adhesives are prevented from being used, so that separation of harmful substances during use can be greatly reduced; meanwhile, in the preparation process of the wood base material, cellulose is partially decomposed, so that the wall surface decoration plate has the good oxidation resistance and moth damage resistance; a biomass liquid can play a role in bacteriostasis; and through addition of TiO2 powder, the finished wall surface decoration plate has the function of decomposing formaldehyde.

Description

technical field [0001] The invention belongs to the technical field of wall decorative board production, and in particular relates to a method for preparing a wall decorative board. Background technique [0002] With the development of society and the improvement of people's living standards, people have higher and higher requirements for the aesthetics and functionality of house interior decoration and furniture. Among them, the beauty of interior wall panels and floors is crucial to the overall interior decoration effect. The decorative characteristics of the surface decoration materials used in the interior decoration process not only determine the aesthetics of the furniture, but also have an important impact on the decorative effect of the entire indoor environment where the furniture is placed. [0003] At present, there are various styles of boards suitable for interior decoration and furniture making on the market. Among them, the original or refined solid wood boar...
