Embodiment 1

[0023] A method for preparing a skin-feeling coating on the surface of a wooden board described in this embodiment comprises the following steps:

[0024] Step 1: Use a microscope to take pictures to collect the texture structure of the cotton fiber surface, and adjust the clarity and brightness of the texture structure;

[0025] Step 2: Import the cotton fiber surface texture described in step 1 into the UV-inkjet 3D printer, set the resolution of the printed skin texture to 1200dpi, the printing speed to 0.3m / s, and the UV wavelength to 380nm;

[0026] Step 3: Sanding the surface of the solid wood board to make the surface roughness 1.0mm;

[0027] Step 4: Using the printing parameters in Step 2, print acrylic resin layer by layer on the surface of the solid wood panel prepared in Step 3 to prepare a skin-feeling coating on the surface of the solid wood panel.

Embodiment 2

[0029] A method for preparing a skin-feeling coating on the surface of a wooden board described in this embodiment comprises the following steps:

[0030] Step 1: Use a scanning electron microscope to take pictures to collect the texture structure on the surface of the matte polyurethane coating, and adjust the clarity and brightness of the texture structure;

[0031] Step 2: import the surface texture of the self-dulling polyurethane coating described in step 1 into the UV-inkjet 3D printer, set the resolution of the printed skin texture to 2400dpi, the printing speed to 0.5m / s, and the UV wavelength to 360nm;

[0032] Step 3: Sanding the surface of the blockboard to make the surface roughness 0.3mm;

[0033] Step 4: Using the printing parameters in step 2, print acrylic resin layer by layer on the surface of the blockboard prepared in step 3 to prepare a skin-feeling coating on the surface of the blockboard.

Embodiment 3

[0035] A method for preparing a skin-feeling coating on the surface of a wooden board described in this embodiment comprises the following steps:

[0036] Step 1: Use a scanning electron microscope to take pictures to collect the texture structure of the cotton fiber surface, and adjust the clarity and brightness of the texture structure;

[0037] Step 2: import the cotton fiber surface texture described in step 1 into the UV-inkjet 3D printer, set the resolution of the printed skin texture to 600dpi, the printing speed to 0.05m / s, and the UV wavelength to 400nm;

[0038] Step 3: Sanding the surface of the plywood to make the surface roughness 3.0mm;

[0039] Step 4: Using the printing parameters in Step 2, print epoxy resin layer by layer on the surface of the plywood prepared in Step 3 to prepare a skin-feeling coating on the surface of the plywood.

Abstract

The invention discloses a preparation method of a skin-touch coating on the surface of a wood board. The method mainly adopts a UV-inkjet 3D printing technology, and designed skin-touch textures are printed on the surface of the wood board, so that the surface of the wood board has an excellent skin-touch performance. The skin-touch coating on the surface of the wood board, prepared by the preparation method disclosed by the invention, is simple in process and high in efficiency, can realize personalized customization of the skin-touch coating, can solve the problems that a traditional processfor preparing a skin-touch coating on the surface of a wood board is complicated, low in efficiency, high in cost and the like, and has a great significance in expanded application and high-additional-value utilization of wood board coatings.

Description

technical field [0001] The invention relates to a method for preparing a skin-feel coating on the surface of a wooden board, in particular to a method for preparing a skin-feel coating on the surface of a wood board by using UV-inkjet 3D printing technology, and belongs to the field of material decoration processing. Background technique [0002] In the 1980s, people’s choice of home wood products was mainly based on practicality, that is, to meet daily functional needs; while modern home wood products must not only meet basic functional needs, but also provide people with a certain sense of situation to meet people's spiritual needs. Therefore, the emergence of skin-feeling furniture not only conforms to the development of the times, but also meets people's emotional needs for home wood products. The skin feeling performance of wood products is mainly produced by coating a layer of coating with special structure and properties on the surface of wooden boards. When human sk...
