Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ceramic-based outer wall material having an uneven pattern on its surface, a ceramic-based plate-like building material used for a ceramic-based outer wall accessory, etc. Regarding makeup method.

[0002]

2. Description of the Related Art Ceramic industrial building materials, such as ceramic external wall materials and ceramic external wall materials, have a surface with an uneven pattern and a makeup such as coloring or patterning in order to give them designability. In recent years, it has been widely used. As shown in FIG. 3, the cross-sectional structure of such a building material generally includes a base material 1 made of a ceramic material that has been aged and cured and having an uneven pattern on its surface, and an adhesive layer 2 made of an adhesive such as acrylic urethane. Is laminated, an ink layer 3 is laminated on the adhesive layer 2, and a clear layer 4 which is a top coat applied as necessary is laminated in order to stabilize the ink of the ink layer 3. Has become.

Such ceramic building materials are generally made up as follows. The makeup method will be described with reference to FIGS. 4 and 5. FIG. 4 shows a transfer paper 6 used for makeup. The transfer paper 6 is made of a resin film 7 such as polyester.
A release layer 8 made of a release material is formed on the surface of, and an ink layer 9 is further laminated. From the transfer paper roll 11 wound with the transfer paper 6 having such a configuration, the transfer paper 6 is arranged such that the ink layer 9 is on the lower side, and the base material 1 having the adhesive layer 2 on the surface and the pressure roll. Transport between 12 and. Above the substrate 1, one or, if necessary, two or more pressing rolls 12 are juxtaposed in parallel at a predetermined interval in the transport direction. All of these pressurizing rolls 12 are in a heated state.

The transfer paper 6 that has been conveyed is conveyed while being pressed against the adhesive layer 2 on the substrate 1 by the pressure roll 12. Then, the ink layer 9 of the transfer paper 6 is transferred onto the surface of the base material 1. Then, with the cooling roll 13, the transfer paper on which the ink layer 9 is used, that is, the release layer 8 as the release paper is used.
Then, the polyester film 7 is wound on the winding roll 14. On the other hand, when the base material 1 to which the ink layer 9 has been transferred is further top-coated and then dried, a plate-like building material having a configuration as shown in FIG. 3 is obtained.

[0005]

In the above makeup method, a sponge roll is generally used as the pressing roll 12 so as not to damage the ceramic plate-like building material, and the pressing pressure cannot be so large. However, when the pressing roll 12, which is a sponge roll, is pressed against the base material 1 having an uneven pattern on the surface, a state as shown in FIG. 6 is obtained. For this reason, there arises a problem that the ink is not sufficiently transferred to the bottom of the recess of the base material 1. In particular, in the case of a plate-shaped building material having a complicated uneven pattern, the product is hardly transferred to the corners of the recess, and the finished product has the ink transferred unevenly, which lowers the commercial value.

The present invention has been made in view of the above technical background, and an object of the present invention is to transfer an ink layer evenly to the bottom of a recess without increasing the pressurizing pressure. It is to provide a makeup method of a ceramic plate-like building material that can be made.

[0007]

Means for Solving the Problems The method for making a ceramic plate-like building material according to the present invention comprises a step of pressing a transfer paper having an ink layer on the uneven surface of a ceramic plate-like building material having an uneven surface. In the makeup method of transferring the ink layer to the surface of a building material, in a press having a pressing surface having an unevenness that matches the unevenness of the ceramic plate-shaped building material, the unevenness of the pressing surface of the press and the unevenness of the plate-shaped building material surface The ink layer is transferred to the surface of the plate-like building material by stacking the two so as to match with each other and pressing the transfer paper.

[0008]

[Function] The pressing surface of the press used in the makeup method of the present invention has unevenness that matches the unevenness of the ceramic plate-like building material,
The transfer paper is superposed with the transfer paper sandwiched so that the unevenness of the pressing surface and the unevenness of the building material surface match each other. Therefore, since the transfer paper is pressed against the concave portion of the building material by the convex portion of the pressing surface, the ink layer can be transferred to the bottom corner of the concave portion of the building material.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. In addition, in each of the drawings, the concavo-convex portion is enlarged for clarity of the present invention. First, the press used in the present invention will be described. The press used in the present invention may be any press as long as it has an unevenness on the pressing surface that matches the uneven pattern of the base material of the plate-like building material to be applied. For example, like the press 20 shown in FIG. 1, a pressure plate 20a is attached to the tip of the piston rod 19,
It is possible to use the press board 20a to which the decorative mold 20b having the pressurizing surface 21 having irregularities is detachably attached by screws, adhesion, or the like. Makeup type 20
Reference numeral b is a resin mold or a rubber mold that is molded so as to have irregularities that directly form the pressing surface 21.

A pressing plate 2 such as the press 20 shown in FIG.
It is also possible to use a press in which a makeup die 20b separately formed is attached to 0a by an appropriate means, or a press in which the makeup die itself forms a pressing plate. It is also possible to use a press in which a silicone resin film or the like having irregularities is directly attached to a pressure plate and the film is used as a pressure surface.
In any case, by appropriately changing the film, the makeup mold, or the like that forms the pressing surface 21 appropriately, it is possible to easily prepare presses corresponding to various uneven patterns of the building material.

The uneven pattern of the pressing surface 21 is most preferably a reverse transfer of the uneven pattern of the building material from the viewpoint of compatibility. However, when the pressing surface 21 is made of an elastic material such as resin or rubber, it may be slightly different. Even if the pattern is different and the height of the unevenness is different, there is no problem because it can be overlapped with the uneven surface of the building material. Next, a method of transferring the ink layer 9 of the transfer paper 6 to the base material 1 of the plate-shaped building material using the press 20 will be described with reference to FIG.

The unevenness of the pressing surface 21 of the press 20 and the substrate 1
Press the press 20 at a position where the surface irregularities match each other.
Set. The transfer paper 6 is set between the press 20 and the base material 1 set in such a positional relationship so that the ink layer 9 of the transfer paper 6 faces the adhesive layer 2 side of the surface of the base material 1. . Next, when the transfer paper 6 is sandwiched and the unevenness of the pressure surface 21 and the unevenness of the base material 1 are overlapped and the ink layer 9 of the transfer paper 6 is pressed against the adhesive layer 2, the ink layer 9 becomes the base material 1.
Transferred to the surface. At this time, the press 20 is heated if necessary. The heating temperature is appropriately set depending on the type of adhesive used in the adhesive layer 2.

If necessary, a top coat may be applied to the substrate 1 to which the ink layer 9 has been transferred and dried. In this way, the ceramic plate-shaped building material can be applied. In the makeup method as described above, since the unevenness of the pressing surface 21 of the press 20 and the uneven pattern of the base material 1 have such compatibility that they match each other, the transfer is performed with a pressure that is not so large. Paper 6
It is possible to superimpose the irregularities of 1 and the irregularities of the substrate 1.
In the superposed state, as shown in FIG. 2, the transfer paper 6 is pressed down to the bottom of the recess of the base material 1. Therefore, even if it is a building material with a somewhat complicated uneven pattern,
The convex portion of the pressing surface 21 allows the ink layer 9 to be transferred to the bottom of the concave portion of the base material 1.

Since the method of the present invention uses a press, the transfer sheet is conveyed to a predetermined position on the substrate, the transfer sheet is stopped from being conveyed, and the transfer sheet is pressed. It needs to be pressed individually, such as sending out. However, by using a press having the same size as the base material to be applied (about 3 m x 1 m), the press transfer can be performed once, or even if the press is smaller than the base material, a plurality of presses can be arranged once. Since the automated makeup operation system shown in Fig. 5 can be used by applying pressure to the surface of the transfer paper or moving the press while the transfer paper is fixed, the press operation can be automated and the productivity is not affected. Never give.

[0015]

Since the makeup method of the present invention uses a press having a pressing surface having an unevenness that matches the unevenness of the plate-shaped building material, the unevenness of this pressing surface and the unevenness of the building material surface should be matched with each other. It is possible to press the transfer paper on top of it and to transfer the ink layer to the bottom of the recess of the building material.

Therefore, even with a building material having a somewhat complicated uneven pattern, the ink layer can be transferred evenly to the bottom of the recess. Therefore, according to the makeup method of the present invention, it is possible to provide a building material with high commercial value without uneven makeup.
