Before describing the invention in more detail, it is to be understood that the words or words used in the specification and claims are not to be construed in a conventional or dictionary sense, It should be interpreted as meaning and concept consistent with the technical idea of the present invention. Therefore, the constitution of the embodiments described in the present specification is merely a preferred example of the present invention, and does not represent all the technical ideas of the present invention, so that various equivalents and variations And the like.
Hereinafter, preferred embodiments of the present invention will be described in detail so that those skilled in the art can easily carry out the present invention.

However, when it is used as a finishing material outside the building, due to acid rain, wind, dust, ultraviolet rays, and air pollution due to environmental destruction, the plate material And the surface of the substrate is easily corroded. In addition, when the elvan plate is used as a built-in finishing material for a public sauna facility, there is a problem that the mold grows easily on the surface of the elvan plate due to the characteristic of elvan, which is weak in moisture.
Accordingly, the inventor of the present invention has developed a new method of processing the elvan sheet material which can solve the above-mentioned problems of the conventional elvan sheet material. In this way, the inventor of the present invention has developed a method of manufacturing the elvan sheet material, Is an architectural exterior material and a building interior material in a high humidity environment, and has a merit that it can be used for a long time while maintaining high durability.
Generally, the elvan plate material contains a certain amount of water. In the method of manufacturing the elvan plate material used in the present invention, first, the natural elbow plate material is first dried.
The step of cutting the elbow plate to a predetermined size may be further roughened before the primary drying step. The cutting area of the plasterboard may be varied according to the intended use of the plate. The thickness of the sheet material is usually in the range of 0.5 to 5 cm, etc., and may be variously formed to meet the intended use of the sheet material. The scope of right of the present invention is not limited to the area and the thickness of the elbow plate.
The reason for passing through the primary drying step is to allow the glaze to penetrate efficiently into the inside of the veneer sheet material through the first and second coating steps using various glazes as described later.
The primary drying step may be carried out at a temperature of typically 50 to 80 DEG C for 1 to 3 hours. If the primary drying temperature is lowered too much, the drying time becomes longer and the moisture removal is not performed sufficiently. Therefore, there is a problem that the glaze applying step described below can not be efficiently performed. If the primary drying temperature is increased too much, There is a concern.
On the other hand, the granite plate having undergone the primary drying step is prepared to efficiently infiltrate and permeate various permeable low-temperature glazes to be described later, and the permeable low-temperature glaze is carried out in three stages to be described later depending on the type thereof.
Firstly, the first application step of applying the first glaze can be performed at room temperature. Therefore, it is advantageous that the application of the glaze is very easy.

On the other hand, the first glaze is prepared by uniformly mixing 15-20 parts by weight of methyl-triethoxysilane or 3-glycidyloxypropyltrimethoxysilane and 12-15 parts by weight of? -Aminopropyltriethoxysilane, Then, 7 to 10 parts by weight of isopropanol and 23 to 28 parts by weight of fine pulverized zeolite were further added to the mixed silane mixture, and the mixture was heated while being heated at a temperature of 50 to 70 캜. 15 to 20 parts by weight of silica sol and 15 to 20 parts by weight of frit ≪ / RTI > by weight to 12 parts by weight of water, and further stirring is carried out.
The fine pulverized zeolite may be selected from the group consisting of clinoptilolite, analcime, chabazite, mordenite, erionite, heulandite, (phillipsite), and ferrienrite (ferrienite).
In this way, the first glaze penetrates deeply evenly into the interior of the elbow plate subjected to the first coating process at room temperature by using the first glaze.
The first coating step using the first glaze can be performed by applying 5 to 8
The first coating step using the first glaze may be performed by a spraying method using a spray gun, which is typically used for coating a glaze, but it is also possible to use various coating methods commonly used in related arts And the scope of the present invention is not limited to such a coating method.
Next, a second application step of applying the second glaze to the surface of the elbow plate is carried out.
The second application step using the second glaze is performed in order to impart various colors to the elvan plate and to impart additional water resistance and chemical resistance.
The second glaze may comprise from 4 to 7 parts by weight of silica sol, titania, or alumina sol and from 5 to 10 parts by weight of a colorant metal ion pigment.
The colored metal ion pigments are iron chloride (FeCl2), zirconium chloride (ZrCl 2), chloride, manganese (MnCl 2), chloride, chromium (CrCl 2), and can be selected at least one from the group consisting of cobalt chloride (CoCl 2) Do.
The second application step of applying the second glaze can also be performed at room temperature. Therefore, it is very easy to apply the second glaze.
And the second coating step using the second glaze can be performed by applying 8 to 10.5
The second coating step using the second glaze may be performed by a spraying method using a spray gun, which is typically used for coating a glaze, but it is also possible to use various coating methods commonly used in related arts And the scope of the present invention is not limited to such a coating method.
The elongated plate material subjected to the second application step is then subjected to a third application step of applying a third glaze containing 3 to 5 parts by weight of water-soluble potassium methylsilicone.
The third glaze used in the third application step serves to impart particularly good water resistance and chemical resistance to the elvan plate.
The third application step using the third glaze can be carried out by applying 16 to 18
As described above, the elvan plate material subjected to the first to third coating steps has the feature that the surface water repellency by spraying is about 100.
After the first coating step to the third coating step, an additional drying step and a baking step may be performed.
The secondary drying step performed after the third application step may be performed by drying the elbow plate material having been subjected to the glaze application treatment at 50 to 80 ° C for 1 to 3 hours, The glaze penetrates evenly into the elvan granite and penetrates deeper into the granite so that it can be stably positioned inside the granite.
Particularly, the second drying step is performed to dry the low temperature glaze penetrated into the inside and inside of the granite processed stone, which has been subjected to the coloring process through the first to third coating steps, to further stabilize the permeability low temperature glaze coloring .
In this manner, the first glaze, the second glaze, and the third glaze are stably penetrated into the rough granite plate up to the second drying step. In order to stably exhibit the chemical resistance and the waterproofing property of the glaze thus penetrated, The following firing step is performed.
The sintering step may be performed after the secondary drying step, and may be performed by heating the elbow plate to a temperature of 650 to 1,150 캜.
