First, a first step (S10) of applying and drying a ceramic paint on a glass plate material is performed.

The ceramic paint is applied to the glass plate by mixing with an inorganic pigment, sprayed by spraying, and dried at about 100 캜 for 30 minutes or more. At this time, the ceramic paint and the inorganic pigment have a mixing ratio of 100: 0.5. The inorganic pigment to be mixed with the ceramic paint may be selected in various colors as required.

In the first step (S10), the ceramic paint comprises 56 to 62% by weight of a binder solution, 3 to 9% by weight of an acetate solvent, 8 to 14% by weight of a cellulosic solvent, 1 to 7% by weight of a first hydrocarbon solvent, 6 to 12% of a first ketone solvent, 8 to 14% by weight of a glass bead and 0.01 to 1% by weight of a dispersing additive. More specifically, the ceramic paint contains 59.2% by weight of the binder solution, 6.4% by weight of the acetate solvent, 10.7% by weight of the cellulosic solvent as the organic solvent, 4.3% by weight of the first hydrocarbon solvent as the organic solvent, Most preferably 8.8% by weight of the first ketone solvent as the organic solvent, 10.7% by weight of the glass beads and 0.1% by weight of the dispersing additive. Also, the acetate solvent is ethyl acetate, the solvent solvent is buthyl cellosolve, the first hydrocarbon solvent is acetonitrile, the first ketone solvent is acetonitrile, The solvent is most preferably methyl isobuthyl ketone. It is most preferable that the glass beads have a particle size of 5 탆 to 10 탆 in order to facilitate discharge during spraying and to improve the adhesive force between the glass plate material and the ceramic paint. Wherein the acetate solvent, the cellulosic solvent, the first hydrocarbon solvent, and the first ketone solvent have a boiling point which is volatilized at a temperature of 200 ° C or lower, and the binder resin, which is a binder resin contained in the binder solution, have.

The binder solution is preferably an ethylcellulose solution. The binder solution is composed of 12 to 18% by weight of ethyl cellulose, 58 to 64% by weight of a second hydrocarbon solvent, and 21 to 27% by weight of a second ketone solvent. More specifically, the binder solution is most preferably composed of 15.2% by weight of the ethylcellulose as the binder resin, 60.8% by weight of the second hydrocarbon solvent as the organic solvent, and 24% by weight of the second ketone solvent as the organic solvent. The second hydrocarbon solvent is toluene, and the second ketone solvent is most preferably methyl ethyl ketone. The second hydrocarbon solvent and the second ketone solvent have a boiling point which is volatilized at a temperature of 200 ° C or lower, and the ethylcellulose which is a binder resin can be dissolved. The ethylcellulose is an ethyl derivative, and is a kind of ether in which hydrogen of the hydroxyl group of cellulose is partially replaced by an ethyl group. The ethyl cellulose has a boiling point of 300 ° C or lower, is easily dried at 100 ° C or lower, and is excellent in gloss and surface hardness. In addition, the ethyl cellulose has an advantage that it is carbonized when sintered at a temperature of 300 ° C or higher, or discolored and remnants are not left, compared with other resins.

A method for producing the ceramic paint will be described below.

First, the ethylcellulose powder is added to a mixture of the second hydrocarbon solvent and the second ketone solvent, and the mixture is heated to about 80 DEG C and stirred to prepare the binder solution. Next, the acetate solvent, the cellosolve solvent, the first hydrocarbon solvent, the first ketone solvent, the dispersion additive, and the binder solution prepared are put into a mixer and stirred for the first time. Next, when the primary stirring is completed by the mixer, the glass beads are charged into the mixer and the secondary stirring is performed to complete the ceramic paint. The ceramic paint thus completed is mixed with the inorganic pigment and applied and dried on the glass plate in the first step (S10).

After the first step (S10), the glass sheet subjected to the first step (S10) is heated to a first temperature range in the tempering furnace (100) for a first required time corresponding to the melting point setting range of the ceramic paint Step S20 is performed. The second step (S20) is carried out in order to impart color and physical properties to the surface of the glass sheet material by strongly fixing and leaving the ceramic paint and the inorganic pigment in the first step (S10) on the surface of the glass sheet material. In this case, the melting point setting range of the ceramic paint is 620 ° C to 680 ° C, the first required time is 9 minutes to 11 minutes, and the first temperature range is most preferably 685 ° C to 710 ° C. More specifically, when the glass plate material that has undergone the first step (S10) is heated from 685 ° C to 710 ° C in the tempering furnace 100, the above-mentioned acetate-based solvent, , The organic solvent such as the first hydrocarbon solvent, the first ketone solvent, the second hydrocarbon solvent and the second ketone solvent is volatilized, and at 200 ° C to 400 ° C, the ethylcellulose and / Only the glass beads and the inorganic pigment, that is, the ceramic component, of the ceramic paint remain on the glass surface at a temperature of 400 ° C or higher, and the first temperature range The glass beads and the inorganic pigment, that is, the ceramic component, remain firmly adhered to the surface of the glass plate at 685 ° C to 710 ° C, The color does not fade and variations such as light and heat is coated with the material surface. At this time, in order to prevent the ceramic component from burning, it is preferable that the heat supply temperature of the glass plate material does not exceed 710 ° C. Since the glass plate material is heated in the reinforcing furnace 100, it is very easy to rapidly heat the glass plate material to the melting point setting range of the ceramic paint.

After the second step S20, a third step S30 is performed to slowly cool the tempering furnace 100 for a second required time so that the glass sheet material that has undergone the second step S20 can be cut. At this time, the second required time of the ceramic paint is 36 minutes to 66 minutes, and the second temperature range is most preferably 60 ° C to 70 ° C. And the second required time is 4 to 6 times the first required time. The glass plate material that has undergone the second step (S20) is in a colored state. The reason why the glass plate material subjected to the second step (S20) in the third step (S30) is not quenched is to prevent the glass plate material that has undergone the second step (S20) from being strengthened to cut the glass plate material to be. Therefore, it is possible to cut the glass plate material in the fourth step (S40) to be described later.

After the third step (S30), a fourth step (S40) of cutting the glass sheet through the third step (S30) to a required size is carried out. The glass sheet material that has undergone the third step (S30) is in a state in which it is colored. That is, in the fourth step (S40), the colored glass sheet is cut to a size suitable for the use. Since the colored glass plate material can be cut in the fourth step (S40), it is possible to mass-produce not only an order production that produces a certain amount according to a specific order.

After the fourth step (S40), the fifth step (S50) of feeding the glass sheet through the fourth step (S40) to the third temperature range in the tempering furnace (100) for the third required time period is performed. In this case, the third required time is 9 to 11 minutes, which is the same as the first required time, and the third temperature range is a temperature equal to or higher than the softening point of the glass plate, Is most preferable.

After the fifth step (S50), a sixth step (S60) is performed in which the glass sheet subjected to the fifth step (S50) is quenched from the tempering furnace (100) to the fourth temperature range during the fourth required time period. In this case, the fourth required time is 9 to 11 minutes, which is the same as the first required time, and the fourth temperature range is most preferably 60 to 70 degrees Celsius, which is the same as the second temperature range. The quenching in the fifth step (S50) is performed by applying compressed air to the glass plate material. The glass sheet material that has undergone the sixth step (S60) is tempered to become tempered glass.

More specifically, the fourth step S40 is a step of cutting the colored glass plate through the first to third steps S10, S20 and S30, and the fifth step S50 and the sixth step S60, Is a process for reinforcing the glass plate material that has been colored and cut through the first to fourth steps (S10, S20, S30, S40), and can be performed according to necessity such as order and use.
