Description

Stone processing method

The present invention relates to a method for processing a stone, and more particularly, to a method for processing a stone that can improve the physical properties and surface color and texture of various building materials or various household articles.

Conventionally, marble is mentioned as what is generally used as a stone used for building and exterior materials, for example. These marbles are imported stone and domestically quarryed stone, but imported stone has brilliant texture and color, while domestically produced marble does not show the same color and texture as imported stone. For this reason, while being used as an expensive imported stone and a high-grade building material, the stone quarryed in Korea is considered to be very poor in quality.

On the other hand, in general, quarry stone in Korea is used as a building bar after only a mechanical process such as a grinding process followed by a cutting process, and since the building attaches these stones to mortars such as exterior walls, As time goes by, it is naturally oxidized by oxygen in the air, thereby easily discoloring.

In addition, once quarried in the quarry, the cross section is roughened by a machine saw or the like, and the mechanical processing of the surface requires close grinding process only after several polishing steps. This not only has the disadvantage that the processing cost is very expensive, but also has the disadvantage of causing problems of stone powder and environmental pollution generated during the polishing process.

In order to avoid such a problem, a method of imparting the uneven texture of natural stone by applying heat to the surface of the stone is also performed, but this also has a problem of being oxidized in air, and this method simply avoids the above problem. It's just a side effect, but it's not a way to actively improve it.

As a result of intensively researching these problems, the inventors of the present invention have led to the present invention, and the object of the present invention is to realize various surface textures and colors even if the stone is collected in Korea, and to be oxidized in air. It is to provide a method for processing a stone that can realize a smooth luster without the worry and the need for several times of polishing processing.

In order to achieve the above object, in the first embodiment of the present invention, a step of preparing a stone, artificially attaching a transfer paper to the surface of the stone over part or the entire surface, and the stone for 3 to 10 hours There is provided a stone processing method comprising the step of heating at 500 to 1,300 ℃, and the step of gradually cooling the heated stone in the air.

In a second embodiment of the present invention, there is provided a step of preparing a stone, artificially attaching a transfer sheet to the surface of the stone over a part or the entire surface, and first heating the stone at 500 to 1,300 ° C. for 3 to 10 hours. The step of cooling, the step of leaving the heated stone in the air to cool slowly and the second heating at 200 to 300 ℃, spraying and applying the glaze, the stone at 500 to 1,300 ℃ for 3 to 10 hours There is provided a stone processing method comprising the steps of tertiary heating, and gradually cooling the stone in air.

In a third embodiment of the present invention, a step of preparing a stone, first heating the stone at 200 to 300 ° C, spraying and applying a glaze, and 500 to 1,300 ° C for 3 to 10 hours Secondary heating, leaving the stone in air to cool it slowly, and attaching the transfer paper to the surface of the stone partially or over the surface of the stone, and the stone at 500 to 1,300 ° C. for 3 to 10 hours. There is provided a stone processing method comprising a third heating step and a step of gradually cooling the stone in air.

In the processing method of the present invention, the heating temperature of the glaze coating is most preferably heated to a temperature of 300 to 300 ° C. for 1 to 3 hours.

In addition, the stone after glazing is cooled after being heated under the conditions of 500 to 1,300 ° C for 3 to 10 hours, preferably 800 to 1,150 ° C for 4 to 6 hours.

EXAMPLE

Hereinafter, preferred embodiments of the present invention will be described below.

Examples of the stone to which the processing method of the stone according to the present invention can be applied include granite (marble), five stone, tin, feldspar and volcanic stone.

In addition, the stone manufactured by the processing method of the present invention can be used not only for building exterior materials, but also for household goods, for example, stone bed stone, stone for cooking stone, kitchen materials, and the like.

Hereinafter, the granite used as a building exterior material is demonstrated to an example.

Stone, which is used as a conventional building exterior material, is cut into a granite collected from a quarry by a machine saw having a size of 170 cm, 70 cm, and 3 cm in thickness.

In this way, the surface of the cut stone (the surface opposite to the outer wall of the building) becomes very rough as a result of cutting by a machine saw. Therefore, conventionally, in order to smoothly process such a rough surface, polishing had to be repeatedly performed three to four times.

However, according to the stone processing method according to the present invention, by applying a glaze on the surface of the stone, and heated at a high temperature and then cooled, the glaze is fixed to the surface of the stone to form a smooth surface like porcelain. In addition, according to the use of the stone can be transferred to the surface by the transfer process to make a stone having a variety of patterns and colors.

This stone processing method will be described in detail.

First, the stone cut to a predetermined size is prepared by washing with washing water.

Next, preheating is performed for 1 to 3 hours at a temperature of 200 to 300 ° C. This preheating is to make the glaze to be applied to the stone in the next step usefully adsorbed on the stone.

After such preheating, the glaze is applied to the surface of the stone, that is, the surface and the side surface exposed when attached to the exterior of the building by spraying or the like. The said glaze is not specifically limited, Usually, what is used for ceramics etc. is used. The glaze smoothes the surface of the stone when the stone is calcined by heating after application, and at the same time, various colors appear depending on the material and type of the glaze.

The glaze-coated stone is heated for 3 to 10 hours at a temperature of 500 to 1,300 ° C., preferably for 4 to 6 hours at a temperature of 800 to 1,150 ° C.

If it is lower than this temperature, sufficient baking effect will not be exhibited. If it is higher than this temperature, a stone will crack or melt | dissolve.

Further, by heating the stone, the crystal water in the stone is released, so that the water adsorption power of the stone can be improved, and impurities in the stone crystal can be removed.

When the stone is heated in this way, the glaze applied to the surface of the stone is fixed, and the texture is smooth, and a unique color according to the material contained in the glaze is expressed.

Therefore, as in the prior art, the oxidation phenomenon of the stone, etc., which appeared during physical and mechanical processing, such as simply polishing the stone, can be prevented, and the gloss that is possible only by the multi-step polishing can be expressed.

Thereafter, the heated stone is left to stand in air and gradually cooled naturally. Of course, it can be artificially cooled, but artificial cooling is not preferable because the stone may deteriorate physical properties.

In addition, in the above embodiment, by applying a colored glaze on the surface of the granite and heating, the color is simply realized, and the surface has a gloss effect, but transfer processing is performed on the surface of the stone to give various patterns and colors. Conduct.

Such transfer processing is performed by attaching a transfer paper having various patterns and colors in general or partially on the surface of the stone, and then heating the stone again at a temperature of 500 to 1,300 ° C. for 3 to 10 hours. By slowly cooling in the air, various patterns can be displayed to suit the characteristics of the product.

In addition, it is also possible to repeat the pre-heating, glaze coating, heating, cooling step as needed again.

Although the transfer was described for attaching the transfer paper after applying the glaze, the transfer may be performed by a process different from this.

That is, in the case of attaching distant limb first and applying glaze, first attach the transfer paper to the surface of the stone, and then heat it at 500 to 1,300 ℃ for 3 to 10 hours, and then leave the heated stone in air Cool.

After that, the stone is preheated again at a temperature of 200 to 300 ° C. for 1 to 3 hours, the glaze is applied by spraying, and the stone is then heated at a temperature of 500 to 1,300 ° C. for 3 to 10 hours and then left in air. The stone can be processed by natural cooling.

In this case, the preheating, glaze coating, heating, and cooling steps may be repeated. On the other hand, after attaching the transfer paper to the surface of the stone, unlike the above-described embodiment, it is possible to provide a stone subjected to the transfer processing only by heating and cooling in the same manner as described above.

As described above, according to the present invention, it is possible to achieve various effects that could not be expected in the conventional building stone.

That is, it is not necessary to perform a simple but time-consuming polishing process, and it is possible to process a stone having a variety of colors, textures and patterns at a large price. Therefore, the import substitution effect can be expected greatly.

In addition, it is possible to prevent the discharge of environmental pollutants such as stone powder according to the conventional grinding process.

In addition, there are various effects that problems such as discoloration due to oxidation, which have appeared in conventional stone, can be easily solved.

Although the present invention has been described above by way of example, it is obvious to those skilled in the art that various changes and modifications can be made without departing from the scope of the appended claims.
