Problems solved by technology

[0003] In the prior art, after the wood is softened by water boiling, microwave heating and other methods, the surface compacted material obtained by surface compaction is unstable in size and easy to recover from compression deformation; while using normal pressure, pressurization, The surface compacted material obtained by impregnating the thermosetting resin with vacuum pressure and other methods, and then compacted on the surface, not only has a deep color but also has a single color, and the production efficiency is low.

Embodiment 1

[0020] (1) drying: sawing and processing the plantation fast-growing timber into a plate with a thickness of 10 mm, and drying it to a moisture content of 8% in a drier or a drying kiln;

[0021] (2) Surface scoring: Use a scoring machine to evenly engrave a groove perpendicular to the wood grain direction on one surface of the board. The width of the groove is 0.5mm, and the depth of the groove is controlled at 1 / 5- Between 1 / 7, the distance between each groove is controlled between 1-4cm, and the shape of the groove is curved;

[0022] (3) Dip dye: Soak the surface part of the board containing the score (the thickness of the surface layer on one side accounts for about 15-25% of the thickness of the board) in acid dyes (such as acid red, acid orange, acid black, etc.) with a concentration of 0.5%. Acid blue, etc.) solution, and a mixture of 0.05% Pingpinga (penetrating agent) and 0.05% alkylphenol polyoxyethylene ether (leveling agent) was added to the dye solution. The con...

Embodiment 2

[0027] (1) drying: sawing and processing the plantation fast-growing timber into a plate with a thickness of 25mm, and drying it to a moisture content of 15% in a drier or a drying kiln;

[0028] (2) Surface scoring: use a scoring machine to evenly engrave grooves perpendicular to the wood grain direction on both surfaces of the board. Between 1 / 10-1 / 8, the distance between each groove is controlled between 1-4cm, and the shape of the groove is linear;

[0029] (3) Dye dipping: Soak all the boards containing the score in a solution of reactive dyes (such as reactive bright yellow, reactive red, reactive blue, etc.) with a concentration of 2.0%, and dodecyl is also added to the dye solution. Sodium sulfate (penetrating agent) 0.15% and NaCl (leveling agent) 1.0% mixed solution, except the above-mentioned raw materials, the remaining percentage content is all water;

[0030] (4) Softening: The plate after dipping is heated and softened by microwave, and the softening temperatur...

Embodiment 3

[0034] (1) drying: sawing and processing the plantation fast-growing timber into a plate with a thickness of 17mm, and drying it to a moisture content of 12% in a drier or a drying kiln;

[0035] (2) Surface scoring: Use a scoring machine to evenly engrave a groove perpendicular to the wood grain direction on one surface of the board. The width of the groove is 0.7mm, and the depth of the groove is controlled at 1 / 5- Between 1 / 7, the distance between each groove is controlled between 1-4cm, and the shape of the groove is the designed wood grain pattern;

[0036] (3) Dip dye: Soak the surface part of the board containing the score (the thickness of the single-sided surface layer accounts for about 15-25% of the thickness of the board) in a direct dye with a concentration of 1.2% (direct bright yellow, direct blue, direct orange, etc.) Dipping in the solution, the mixed solution of 0.1% Pingpinga (penetrating agent) and 0.5% of alkylphenol polyoxyethylene ether (leveling agent) ...

Abstract

The invention relates to a preparation method of a colored surface compressive plate, in particular to solving the technical problem of providing a manufacturing method of a colored surface compressive plate featuring high surface layer density, dimensional stability, strong operability and diverse colors which are close to the colors of natural precious wood. The technical scheme for solving theproblem is as follows: the method comprises the following steps: (1) drying and controlling the water content between 8% and 15%; (2) notching surface layer and controlling the width of grooves between 0.5mm and 1.0mm; (3) dipping dye, namely soaking part of the surface layer with notches of the plate into water-soluble dye solution at concentration of 0.5-2.0% for impregnation; (4) softening andcontrolling the softening temperature between 120 DEG C and 140 DEG C; (5) compressing surface and controlling the compression ratio between 15% and 50%, the hot pressing temperature between 160 DEG Cand 180 DEG C and the unit pressure between 1.5MPa and 4.5MPa; and (6) setting. The method is suitable for such fields as furniture manufacturing, indoor decoration and the like.

Description

technical field [0001] The invention relates to a preparation method of a colorful surface-densified plate. It is suitable for furniture manufacturing, interior decoration and other fields. Background technique [0002] At present, my country has entered the stage of developing and applying a large number of plantation fast-growing wood, but the material of plantation wood is loose, low density, and poor in mechanical strength, so it cannot be directly used as materials for furniture and interior decoration. In order to overcome the shortcomings of artificial forest wood, it is usually strengthened by impregnation and compaction methods. Among them, ordinary compressed wood, surface compacted wood (surface compacted wood), and compressed plastic wood made by compaction methods are used. The hardness, density, and strength of plantation wood have been greatly improved, and the use of inferior wood has been realized. In particular, the surface compacted material can concentr...
