Description

Manufacturing method of multicolor decorative board

The present invention relates to a manufacturing method of a multi-colored decorative board, which will be described in more detail, such as wood furniture such as tables, counters, furniture, sinks, and audio equipment cases, wooden building materials such as floorboards, wall materials, interiors, interior equipment, etc. The present invention relates to a method for producing a multicolored decorative plate that can express colors having different colors on the surface of the decorative plate used as a surface agent.

In general, the surface agent used as a surface plate such as a table or a floorboard is a piece of wood alone or a thin plate made of wood attached to a plywood board. And there is a problem with not only the complaints of consumers in durability, but also to obtain a decorative plate of different colors.

In addition, conventionally, in order to obtain a color plate having a different color on the decorative plate, a method of printing directly on the decorative plate and a unit sheet having a color printed on the upper part of the base plate, and a unit sheet having a different color on the upper part is cut and pressed. There is a way to work.

In the former case, the general offset printing or master printing method cannot be applied to the surface of the finished cosmetic plate, and various colors are expressed by using a conventional silk printing or coating printing method.

However, the silk printing has a problem in that the work process is increased due to the separate separation plate when printing the surface of the decorative plate, because the printing process by making each separation to take different colors, causing a waste of printing costs.

In addition, the coating printing is a color plate with a different color on each of the decorative plate, there was also a problem that the price is expensive when printing on the decorative plate using the coating printing.

In the latter case, as shown in FIGS. 6 and 7, the unit sheets 21 in which colors are printed with the same size as the base plate 20 are stacked on the upper part of the base plate 20 having multiple layers, The unit sheet 21 and the color of the unit sheet 21a having different colors are cut on the upper portion thereof, stacked at a desired position, and pressed by a multi-stage press 30 to complete a desired multicolor cosmetic plate.

In particular, in the preliminary step of the pressing operation, that is, the base plate 20, the unit sheet 21 mounted on the upper portion of the base plate 20, and the upper portion of the unit sheet 21 are placed on a different color. And a unit sheet 21a having an area smaller than that of the unit sheet 21 is stacked. Thus, the base plate 20, the unit sheet 21, and the other color unit sheet 21a are formed. As shown in Fig. 40 is made of a state of the decorative plate 40 is stacked between a plurality of presses 30 to perform a press operation.

However, in the case of performing the press work by stacking the decorative plates 40 as described above, the unit sheet 21a of the uppermost color forming the decorative plate 40 has an area larger than that of the unit sheet 21 immediately below. During this pressing operation, the thickness of the portion in which the unit sheets 21a are laminated is thick, and the portion in which the unit sheets 21a are not laminated becomes thin, which causes problems in the press 30.

In addition, the completed makeup plate 40 after the makeup plate 40 is compressed has a problem that the surface is uneven due to the protrusion of the other color unit sheet 21a.

The present invention has been invented to solve the above problems, by using a unit sheet having a projection surface and a color surface at the top of the makeup plate, and by using a unit sheet having a color surface at the bottom thereof, It is an object of the present invention to provide a method for producing a multi-colored decorative board that can obtain a color decorative board.

In addition, since the size of the unit sheet having the projection surface and the color surface laminated on the top is the same as the size of the base plate, it is not difficult to press multiple stages, and the size of the upper unit sheet is the same so that the productivity can be improved. An object of the present invention is to provide a method for producing a multicolor decorative plate.

In order to achieve the above object, the present invention impregnates the paper on the roll while passing through the impregnation tank containing the chemical resin, and the chemical resin is impregnated in the paper, which is dried by a cutting machine to dry the chemical resin. A first step of forming a unit base plate by cutting to a standard; a second step of forming a unit sheet in a roll-like sheet having a generally colored surface; and a roll-shaped having a color surface and a projection surface in the same process as the first step. A third step of forming a unit sheet by cutting the sheet to the same size as the base plate, and laminating the unit base plate to form a base plate, wherein the unit sheet of the second process and the unit sheet of the third process A fourth step of laminating and heating and pressurizing the manufactured products laminated in the fourth step by heating and pressing means such as a hot press capable of heating and pressing. It is characterized by consisting of a fifth process of completing a plurality of cosmetics.
