Detailed Description of the Invention

[0001]

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

[0002]

2. Description of the Related Art Ceramic board materials such as fiber reinforced cement boards have been widely used as building board materials.
If this seed plate material is left as it is, the surface is a gray white to gray black achromatic color and poor in designability, and since it has surface water absorption, it is usually applied with various colors to impart surface coloring and waterproofness. Be seen. Further, for the purpose of imparting a design property, for example, an uneven pattern of various contours such as a masonry of natural stone is provided on the surface, and a natural stone-like pattern is printed on the convex part by a transfer method to enhance the design property. Things are often done.

In the surface makeup by the transfer method, the surface of the natural stone is photographed and used as the original of the transfer film. Therefore, the finished wall appearance is constructed by the factory-produced wall board. Regardless of this, it has an advantage that it can have an appearance very similar to the natural material that is the subject, and that an outer wall with a high-class feeling can be easily and inexpensively constructed.

[0004]

[Problems of the prior art] However, in the case of applying a wallboard by the above-mentioned transfer method, there is no problem if the surface of the wallboard as a base material is a smooth surface, but the surface of the wallboard is provided with a concavo-convex pattern. In this case, when the transfer film is pressed and transferred to the surface of the wall plate, a pattern pattern is printed up to the inside of the joint concave portion, and the boundary between the concave joint and the convex pattern portion becomes unsightly.
In particular, if the recess pattern is shallow, the elasticity of the transfer roll may transfer the pattern to the bottom surface of the recess pattern, which may make it difficult to distinguish between the projection and the recess.

In order to solve such a problem, 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, but in this case, the uneven pattern of the wall plate is formed. If there is a change, it is necessary to recreate the transfer film from the original photograph, and there is a drawback that the efficiency becomes very poor in the case of high-mix low-volume production.

[0006]

SUMMARY OF THE INVENTION In view of the above problems, the present invention ensures reliable pattern transfer only on the convex pattern surface when surface makeup is applied to the surface of a ceramic board having an uneven pattern on the surface by a transfer method. The object of the present invention is to provide a method for applying a ceramic plate material that can be applied and can efficiently respond to pattern changes.

[0007]

Means for Solving the Problems That is, the method of applying a ceramic plate material according to the present invention is a method of applying a surface makeup to a surface of a ceramic plate material 1 having uneven patterns 1B and 1A by a transfer method. It is characterized in that transfer is performed by using a transfer film 3 having a uniform pattern printed on the entire surface of a protective film 3B provided with a release layer 3A only on a portion corresponding to a convex pattern surface 1A of a plate material 1. .

[0008]

In the present invention, when makeup is applied only to the convex pattern on the surface of the ceramic plate by the transfer method, a protective film having a release layer only on the portion corresponding to the convex pattern surface of the ceramic plate is used as the transfer film. A transfer film with a uniform pattern printed on the entire surface is used. Therefore, the transfer is performed only on the pattern corresponding to only the convex pattern surface, and the transferred pattern portion corresponding to the concave pattern is peeled off together with the protective film and is not transferred to the ceramic plate material. Therefore, it is possible to print the contour of the convex pattern clearly.

As a means for providing the release layer only on the portion corresponding to the convex pattern surface of the transfer film, for example,
It can be easily obtained by making a master mold using a plastic rubber plate etc. with a press roll that gives an uneven pattern to the ceramic plate material, evenly applying a release agent on the surface of this master mold, and then transferring this to a protective film . Then, the original pattern is printed on the entire surface of the obtained protective film.

[0010]

Embodiments of the present invention will be described below. FIG. 1 is an enlarged sectional view of a transfer film, and FIG. 2 is an enlarged sectional view showing a process of an embodiment of the present invention.

(Example) A plastic rubber plate is pressed by a roll press machine for imparting an uneven pattern to the surface of a ceramic plate material to form a mother plate having an uneven pattern like natural masonry on the surface,
A release agent 3A is evenly applied to the surface, and a protective film 3B is pressed onto this mother die to form a protective film 3B in which a release layer 3A is provided only on the portion corresponding to the convex pattern surface 1A of the ceramic plate material surface. Then, a transfer film 3 was obtained by printing 3C using a film obtained by photographing the surface of a natural stone on the entire surface as an original.

Next, a cement plate 1 having an uneven pattern with an uneven difference of 2 mm is formed on the surface of the cement plate 1 by a roll press machine having the above uneven pattern, and after curing and curing, an adhesive 2 is uniformly applied to the entire surface of the cement plate 1 and dried. Let Next, the transfer film was placed on the surface of the cement plate 1 and pressure was applied by the heated sponge roll 4 as shown in FIG. 2 to transfer, and then the protective film 3B of the transfer film 3 was peeled off. At this time, the printed pattern 3C corresponding to the concave pattern 1B was peeled off while adhering to the protective film 3B, and only the printed pattern 3C portion corresponding to the convex pattern 1A provided with the release layer 3A was transferred to the cement plate 1. After that, a transparent clear top coat layer was applied to the surface to finish the makeup.

(Comparative Example 1) The same cement board 1 as in the example
The surface makeup was performed in the same manner as in Example except that a transfer film having a uniform pattern printed on the entire surface was placed thereon and transferred without the treatment of a release agent. (Comparative Example 2) A surface makeup was applied in the same manner as in Comparative Example 1 except that the cement board 1 having a natural stone masonry-like concavo-convex pattern with a surface irregularity difference of 5 mm was used.

When the appearances of the example and the comparative examples 1 and 2 are compared, the pattern of concave portions 1B and the pattern of convex portions 1A are clearly distinguished and printed even though the pattern of the example is a shallow concave pattern. However, in the case of Comparative Example 1, the pattern was transferred to the bottom of the concave pattern 1B in almost the same tone as the surface of the convex pattern 1A, and the concave pattern became unclear after a short distance. In the case of Comparative Example 2, the pattern was not transferred to the bottom surface of the concave pattern 1B, but as shown in FIG. 3, the roll was compressed to the side wall portion 1C extending from the convex pattern surface 1A to the bottom surface of the concave pattern 1B. The protruding transfer part 3'is seen, and the concave pattern 1B
It became a pattern with an unclear outline.

[0015]

As described above, according to the present invention, when a transfer film is used to form a printed pattern, it is possible to make a decorative print in which the convex pattern and the concave pattern are distinctly different from each other. In addition to having the effect that mass production of high-quality wallboards can be carried out at low cost, when making a transfer film, you can change the pattern because you can change the position of applying the release agent on the protective film without changing the original film size. If there is a problem, it can be dealt with promptly, and it has the effect of being able to efficiently produce even a large variety of products in small quantities.
