Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a post-

The present invention relates to a post-processing apparatus and method for a color board, and more particularly, to a method and apparatus for post-processing a color board, And more particularly, to a post-processing apparatus and method for a color board capable of manufacturing an MDF color board having enhanced permeability and water resistance through a process.

As is known, MDF (Medium Density Fiberboard) is made by joining wood fiber obtained by high-temperature heat treatment (softening with steam after making chips) with synthetic resin adhesive by using molding material and hot pressure It is a wood-based plate product with a density of 0.4-0.8g / cm ³ , which can be produced from 3.0mm to 30mm in thickness.

It is possible to carry out complicated machining operations with uniform fiber distribution over the entire thickness without complicated machining operations without rupture of the side or sides. Therefore, MDF is used for table top plate, door, drawer front etc. do.

It is also well suited for smoothing, firm, and overlaying or painting decorative films or veneers. Due to its excellent stability, machinability and high strength, it can be used in place of ordinary wood for drawer sides, cabinet rails, mirror frames, and modeling.

Meanwhile, the MDF color board that forms the color in the above MDF is similar to the general MDF sheet manufacturing process. The process of manufacturing the MDF color board is similar to that of the general MDF sheet manufacturing process. The color is formed by putting it in the dyeing process, and the chip formed with the color is laminated and compressed by adhering with the adhesive.

The MDF color board made in this way is able to realize the strong performance against discoloration, flame retardation, moisture and waterproofing by the exposure of direct sunlight which is a disadvantage of MDF, and it is possible to realize smooth and beautiful color of the primary color pastel tone without additional painting, It is various, and it keeps uniform color from the surface to the inner part, so it can be processed even if it is cut in any place, so it is easy to process, and uniform color is obtained without separate edge processing And its use is expanding by combining color-specific boards according to design.

In other words, MDF color boards have unique colors and textures, so they are molded, doors, wall panels, children's props and interiors, small furniture. It is widely used for interior and furniture applications. In addition, the density of the MDF color board is about 20 to 30%, which is about 750 g / cm 3 to 820 g / cm 3, compared with the density of general MDF of 650 g / cm 3 to 750 g / cm 3.

However, in the case of a general untreated color board as described above, the dye itself is vulnerable to moisture because of its low water resistance, and when the water drops are splashed or dropped on the surface of the board, the color changes.

In order to solve these problems, the product performance is further added by adding a post-treatment process such as painting on MDF color board for the purpose of flame proofing, scratch prevention, prevention of contamination, prevention of moisture penetration.

However, existing UV coating, poly-film coating or urethane coating method is not environment-friendly and is not free from harmful substances such as T-VOC. When it is coated on MDF color board surface, the coating is placed on the board and hardened. And the coating is cured in the state of being immersed in the surface of the color board so that it is bundled and the pastel texture of the fine and soft particles is changed into an artificial texture like a plastic surface to significantly reduce the value of the product.

In addition, the cured coating film is hard and it has a disadvantage in that it can not express clear texture because it is cracked or crushed when various indentations are formed after painting.

That is, the surface-treated color board has another problem that the texture and color completely change when the conventional UV coating, poly-film coating or urethane coating is performed.

On the other hand, a conventional method of manufacturing a general MDF color board is disclosed in Korean Patent Registration No. 1424800.

A method of manufacturing a conventional MDF color board is a method of forming a convex pattern on a board by passing a board through a rolling roller having a convex pattern formed on a surface of the board, The pattern is partially peeled off or scratched to form a pattern on the board in the shape of a pattern layer formed on the rolling roller.

Thus, when the surface of the board is rolled, the patterned layer of the rolling roller partially scratches or scratches the UV coating layer formed on the board surface (scratching phenomenon) , So that the scratch marks of the UV coating layer remain and appear to form a pattern on the board.

Further, when the UV coating layer formed in the conventional MDF processing method is partially peeled off or defective, it is regarded as a defective product and is discarded. By using the scratch portion of the UV coating layer in reverse, the MDF It is used to form the pattern of the color board.

However, even in the case of the method of manufacturing the MDF color board in which the conventional pattern is formed as described above, the UV coating layer is assumed as a premise, so that the portion pressed by the roller is bundled.
