Abstract

PURPOSE: A method for producing patterns on a skin door is provided to produce patterns perfectly same as patterns and texture of real trees on a surface of a skin door and to produce two patterns of two colors on a surface of a skin door, thereby increasing quality of the product and eliminating the conventional complex assembly process as well as saving the cost. CONSTITUTION: A skin door(1) processed to have prominences and depressions according to the desired design is provided and polished, as needed. An adhesive is applied over a surface, optionally treated, of the skin door(1). A transfer paper(3) is cut and placed over the surface with the adhesive applied. The transfer paper(3) can be placed locally where different colors or patterns are desired. A jig(4) having prominences and depressions corresponding to those of the door is fixed at a surface plate(5) and the skin door is placed over the jig(4) with the surface having the transfer paper(3) facing downward and the prominences and depressions being matched. A second transfer paper(6) is covered over the structure and membrane pressing process is performed by pressing another surface plate(8) having a silicon rubber(7) on the surface at 90 to 160 deg.C and 4 to 6 bar for 90 to 240 seconds.

Description

Oral pattern manufacturing method on a skin door

According to the present invention, the thermal transfer film is brought into close contact with a substrate of a shape-finished fiber board by a vacuum press, thereby enhancing the monotony of the conventional skin door, and simplifying the cumbersome process of the conventional frame door and reducing costs. The present invention relates to a method of forming a surface pattern of a skin door using a thermal transfer method, which can replace wood required for a wooden door.

A door, such as a conventional door, is made of expensive solid wood or a fiberboard processed into shape.

Since wood is mostly imported, it is expensive and difficult to use widely. Instead, there is a method of surface-treating fibrous plates and the like or forming patterns of wood.

However, for example, the skin door is made of a fiber board as described above, the surface is used to paint a common solid color such as white, off-white, etc. This is a disadvantage that the quality of the product does not look very good.

In addition, there is a method of forming some wood patterns on the surface, but it was difficult to express the texture of wood or the texture of wood.

The object of the present invention was invented in view of the above-mentioned point, and it can not only show the texture of the wood and the texture of the wood almost completely, but also can form two colors and patterns on the surface at the same time to improve the product quality. It is an object of the present invention to provide a method that can simplify the cumbersome process of a built-in door and can replace wood depending on imports. Hereinafter, the method according to the present invention will be described in detail with reference to the accompanying drawings.

1 to 4 is a view showing a pattern forming method according to the present invention in order

Method for forming a surface pattern according to the present invention, after applying the adhesive to the disc, the step of temporarily bonding the transfer paper (3); A step of tightly fixing the temporarily bonded disc on the lower surface plate 5 on which the jig 4 is fixed; Covering the whole second transfer paper 6 thereon; Thermally pressurizing and transferring the upper surface plate 8 on which the silicon rubber 7 is formed; Lifting the upper surface plate 8 and removing the second transfer paper 6 to expose the primary transferred surface; And removing the transfer paper 3 under the second transfer paper 6 to expose the transferred surface.

Hereinafter, other configurations and features of the present invention will be described in more detail.

First, as shown in Figure 1, the skin door 1 is processed by giving the yin and yang in the shape required for the design of the product, and if necessary, depending on the surface condition of the surface polishing to improve the adhesive force, then the adhesive ( 2) In particular, a modified polyurethane aqueous adhesive is evenly plotted as an example, which is preferable in this embodiment. This application can be done by hand or by a bond application machine.

As shown in the example of FIG. 2, the transfer paper 3 is cut on the surface of the skin door and placed on the skin door 1 to which the adhesive is applied, thereby temporarily attaching it.

In this case, when it is desired to give two or more colors or patterns, the transfer paper 3 is cut to the part where two or more patterns or colors are to be shown and primary temporary bonding is performed.

3, the jig 4 opposite to the yin-yang of the skin door is fixed to the lower surface plate 5, and then the skin door 1, to which the transfer paper 3 is temporarily attached, is yin-yang over the jig 4 Place it to match. Then, the second transfer paper 6 is entirely covered, and then a membrane press work is performed. This operation is performed by pressing down the upper surface plate 8 on which the silicon rubber 7 is formed on the surface.

At this time, the upper and lower surface plates (8, 5) of the vacuum press are brought into close contact with each other to create a vacuum state, and a high temperature of about 90-160 degrees Celsius and a high pressure of about 4-6 bar (BAR) are transferred to the silicon rubber (7). Press the adhesive for about 90-240 seconds to get a strong bond.

Then, when the second transfer paper 6 film on the skin door surface from the vacuum press is removed, a pattern formed on the surface of the second transfer paper 6 film is printed on the surface of the skin door 1. At this time, the transfer paper 3 under it remains intact. Therefore, the other surface which is not covered with the transfer paper 3 is in the state of being primary-transferred. Then, the transfer paper 3 is peeled off second. Then, the pattern or color of another shape formed on the lower surface of the second transfer paper 6 is transferred to the surface of the skin door under the other pattern or color.

Then, as shown in FIG. 4, different patterns may be simultaneously displayed. Finally, the surface is finally urethane coated.

Although the description of the present invention has been described as applying the method of the present invention to embodiments of the skin door only, it is merely exemplary and may be a surface or wood such as similar furniture other than the skin door, for example, various agricultural, table, etc. Of course, it can be applied to any other upholstery that replaces.

In this case, it is applicable regardless of whether the surface is an uneven surface or a flat surface.

According to the present invention as described above, the conventional skin door is a monochromatic coating, such as white off-white coating is the most widely commercialized, but according to the present invention is an appearance that can express the texture of the wood and the texture of the wood excellently Luxurious products can be mass produced at low cost.

In addition, according to the present invention, the texture of the wood can be best expressed and there is an advantage that can express the effect of the existing solid wood frame door as it is.

In addition, according to the present invention, instead of the complicated assembly process of the existing solid wood frame, there is an advantage that can be freely simultaneously expressed on the surface of the skin door by two or more freely one membrane operation of the pattern or color of the desired pattern.

In addition, since the method according to the present invention does not perform the surface painting work, etc., there is an advantage that can prevent various environmental pollution appearing during the painting work and can also promote the safety of the worker. In other words, this is an environmentally friendly brain method.

In addition, according to the method of the present invention, a membrane press is applied to a material surface such as a medium density fiber board (MDF) or a hard board, which is a material of a skin door, and exhibits almost the same texture as that of solid wood, which is expensive. There is also a substitute effect of wood.
