Recently, as interest in the residential environment has increased, the use of eco-friendly building stone has been increasingly used as interior and exterior materials of buildings.

Here, stone is a generic term of a raw material of a rock or a civil engineering and building material obtained by its processing.

The stone is easy to see from the surroundings, but it has a natural beauty and deep beauty. It is well suited to any place and has a unique beauty that does not bother over time.

Moreover, although the stone types are various, the texture of each stone is wide and the choice is wide.

For example, many kinds of marble such as granite, serpentinite, andesite, tuff, diorite, gabbro, slate, etc. have been actively used as interior materials for interior and exterior as well as marble widely used from the past.

In particular, natural marble, artificial marble and granite are widely used as interior and exterior materials for buildings.

As described above, such a stone is a highly desirable building material which not only exposes the building with high quality, but also has durability and is capable of maintaining the quality for a long time and does not emit harmful substances to the human body.

However, these stones are difficult to be collected and processed, and accordingly, they are not widely used because they are formed at a high price.

In particular, it is difficult to process a conventional stone in the form of a panel having a thickness less than a certain thickness due to an impact accompanied by a cutting process, and even if a thin panel form is obtained, it is likely to be broken easily.

In addition, there is a problem that economical efficiency and workability are deteriorated due to excessive weight at the time of construction. As a result, when natural stone such as marble is used as interior and exterior materials for construction, there is a problem that construction costs are incurred in addition to the cost of marble itself.

In order to solve such a problem, a method has been developed in which a stone such as marble has been cut to a predetermined thickness and the cut stone plate is adhered to a general synthetic resin panel.

In addition, glass is used for building exterior materials, and techniques for screen printing various patterns such as granite and marble as described above on a glass surface have been developed.

The present invention is also applied to such a technique, which will be described in the prior art.

As shown in FIG. 1, reference numeral 11 denotes a substrate (glass), 12 denotes a printing layer, 13 denotes a white opaque glaze layer, and a surface of natural stone to be reproduced, such as marble or granite, , Cyan (C), yellow (Y), and black (B); Based on the color-separated film, the glaze which is colored in four colors of red, blue, yellow and black on the surface of the glass is printed with a silk screen, respectively, and a second, opaque glaze ; And calcining it in a calcining furnace at a temperature of 450 to 800 ° C. for 3 to 30 minutes, followed by cooling.

In the case of Fig. 2, the marble pattern was put on the glass to reproduce the marble pattern, but there was a lot of feeling of lowering of stability. Such a screen printing method is printing on glass, There has been no study on how to apply this to marble patterning.

In addition, natural marble is expensive, and the existing natural marble is composed of mostly calcareous material, which causes corrosion on the surface due to acid rain or ultraviolet rays during the exterior construction, which causes difficulty in exterior construction. In the case of granite, There was a problem of falling.
