DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of making a ceramic plate, and more particularly, to an improvement in a method of applying a makeup to a surface of a ceramic plate having an uneven pattern.

[0002]

2. Description of the Related Art Conventionally, ceramic boards such as fiber-reinforced cement boards have been widely used as building boards.
If this seed plate is left as it is, it has an achromatic color of gray-white to gray-black, poor in design, and has surface water-absorbing properties. Will be Furthermore, for the purpose of imparting designability, for example, a natural stone masonry-like uneven pattern with various contours is added to the surface, and a natural stone-like pattern is printed on the projections by a transfer method to enhance the designability. Things are often done.

[0003] In the surface decoration by this transfer method, a photograph of the surface of natural stone is taken and used as the original format of the transfer film. Therefore, the appearance of the finished wall is constructed by factory-produced wall boards. Regardless, the appearance can be made very similar to the natural material used as the subject, and there is an advantage that an outer wall having a high-grade feeling can be easily and inexpensively constructed.

[0004]

Problems with the prior art However, in the case of decorating a wallboard by the above-described transfer method, there is no problem if the surface of the wallboard as a substrate is a smooth surface, but the surface is provided with a joint-like uneven pattern. In the case of (1), when the transfer film is transferred to the wall plate surface by pressing, the pattern is printed up to the joint concave portion, and there is a disadvantage that the boundary between the concave joint and the convex pattern portion becomes difficult to see.
In particular, if the concave pattern is shallow, the pattern is transferred to the bottom of the concave pattern by the elasticity of the transfer roll, and there is a drawback that the distinction between the convex part and the concave part may not be obvious.

[0005]

DISCLOSURE OF THE INVENTION In view of the above problems, the present invention provides a reliable pattern transfer only to the surface of a convex pattern when a surface decoration is applied to the surface of a ceramic plate having an uneven pattern on the surface by a transfer method. It is an object of the present invention to provide a method of applying a ceramic board material that can be applied.

[0006]

That is, the present invention relates to a method for making a ceramic plate by applying a transfer method to a surface of a ceramic plate 1 having a concavo-convex pattern 1B, 1A on its surface. The transfer is performed by using a transfer film 3 in which a pattern is printed only on a portion corresponding to the convex pattern surface 1A of the plate material 1.

[0007]

In the present invention, in the case where makeup is applied to only the convex pattern on the surface of the ceramic industry plate material by the transfer method, a transfer film having a pattern printed only on the portion corresponding to the convex pattern surface is used as the transfer film. Therefore, the transfer is performed only on the convex pattern surface, and even if the transfer film is pressed against the concave surface, the pattern is not transferred on the concave bottom face. Therefore, printing with clear contours is possible. In addition, as a means to print the pattern only on the portion corresponding to the convex pattern surface of the transfer film, the natural masonry wall that was the subject of photography was printed on the transfer film, and the In addition to adding a pattern and transferring it to it, when photographing the appearance of natural stone and printing this original on a transfer film, the part corresponding to the concave pattern of the ceramic plate is made plain by masking etc. There are two ways to transfer to the surface of the base plate.

[0008]

Next, an embodiment of the present invention will be described. FIG. 1 is an enlarged sectional view showing a process of an embodiment of the present invention.

(Example) A cement board 1 having a natural masonry-like uneven pattern having a difference of 2 mm on the surface was prepared, and an adhesive 2 was uniformly applied to the entire surface of the cement board and dried. Next, a portion corresponding to the concave pattern 1B on the surface of the cement plate 1 is heated by placing a transfer film 3 which is made plain by masking at the time of printing, and is pressed by a sponge roll 4 as shown in FIG. Transfer to the surface, then transfer film 3
Was peeled off the release paper 3A laminated on the substrate. Thereafter, a top coat layer of a transparent clear was applied to the surface to complete the makeup.

(Comparative Example 1) The same cement plate 1 as in the embodiment.
Then, surface transfer was performed in the same manner as in Example except that a transfer film on which a uniform pattern was printed was placed and transferred. (Comparative Example 2) Surface makeup was performed in the same manner as in Comparative Example 1 except that a cement board 1 having a natural masonry-like uneven pattern having a difference of 5 mm on the surface was used.

When the appearance of the embodiment is compared with that of Comparative Examples 1 and 2, the recessed pattern 1B and the projected pattern 1A are clearly distinguished and printed in the case of the embodiment, despite the shallow recessed pattern. However, in the case of Comparative Example 1, the pattern was transferred to the bottom of the concave pattern 1B with almost the same tone as the surface of the convex pattern 1A, and the concave pattern became indistinct when slightly separated. Further, in the case of Comparative Example 2, the pattern was not transferred to the bottom of the concave pattern 1B, but the roll was compressed onto the side wall 1C from the convex pattern surface 1A to the concave pattern 1B bottom as shown in FIG. The transfer part 3 'protruding due to the above is seen, and the concave pattern 1B
The pattern became unclear.

[0012]

As described above, according to the present invention, when a printed pattern is applied to the surface with a transfer film, it is possible to apply decorative printing in which the convex pattern and the concave pattern are clearly different from each other. In addition, since it can be implemented at a low cost, there is an effect that wall panels having a high-quality feel can be mass-produced at a low cost.
