DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a method of manufacturing a ceramic glass using a nano-micro-emery according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a schematic process flow diagram of a method of manufacturing a ceramic glass using a nano-micro-emery according to an embodiment of the present invention.

Referring to FIG. 1, a method (S100) for manufacturing a ceramic glass using a nano-micro-goldsmill according to the present invention is a method for manufacturing a ceramic glass having excellent brightness and hardness, and includes a processing step (S110) and a sanding step S120), a cleaning step S130, a ceramic ink mixture preparation step S140, a printing step S150, and an enforcing step S160.

The processing step S110 is a step of processing the raw material glass plate before processing so as to have a glass of a desired size and shape.

For convenience of explanation, in this step, a soda lime raw material used as a raw material of a glass substrate is generally processed as a raw material.

First, the soda lime disc is cut to meet predetermined specifications. After the surface of the glass substrate is cut after the cutting, cleaning water is sprayed to remove glass dust generated during cutting and polishing.

The sanding step S120 is a step of smoothing the surface of the cut glass substrate so that the printing quality of the ceramic ink mixture can be improved in the printing step S150 described later. In the present invention, sand particles are sprayed onto the glass surface to sand the surface of the glass substrate.

In the sanding step (S120) in this embodiment, the sand particles having a particle size of 200 mesh are used, and the sand particles are sprayed on the entire surface of the glass at a pressure of 4 kg / cm2.

However, in the present sanding step S120, fine grooves are formed on the surface of the glass substrate by the sand particles to be injected, and these fine grooves serve to accommodate the gold wire in the cleaning step S130 described later.

FIG. 2 is a schematic view showing that a gold streak remains on a glass substrate through a cleaning step of the method of manufacturing a ceramic glass using the nano-micro-emitter of FIG.

The cleaning step S130 is a step for removing the sand particles injected in the sanding step S120 and remaining on the surface of the glass substrate 20. The cleaning agent mixing step S131 and the detergent injection step (S132).

The cleaning agent mixing step (S131) is a step of manufacturing a cleaning agent used in cleaning. In the present invention, a cleaning agent is prepared by mixing a predetermined amount of a softening agent with a predetermined liquid. In this embodiment, a cleaning agent is prepared by mixing a gold-plated steel and water at a weight ratio of 1: 1.

However, the liquid and the weight ratio used as the cleaning agent are not limited to the above-mentioned contents. In addition, it is preferable that the gold stones mixed in this step are provided as fine particles having a very small particle size so as to remain in the fine grooves formed in the organic substrate in the cleaning agent injection step (S132) described later.

The abrasive grains used in the present embodiment are subjected to a plurality of processes of pulverizing and cooling in a sealed chamber at a high temperature, thereby reducing the particle size.

The cleaning agent spraying step (S132) is a step of spraying the prepared cleaning agent onto the surface of the glass substrate (10). In this step, the cleaning agent containing the emery 20 is shot blasted to remove the sand remaining on the glass surface.

At this time, the liquid water serves to directly remove the sand on the surface of the glass substrate. As shown in FIG. 2, some of the stoneports 20 remain in the fine grooves formed on the surface of the glass substrate, while the sandbrake 20 that is shot blasted removes the remaining sand on the surface of the glass substrate. The stoopedite 20 remaining on the glass surface directly reacts with silicon and ceramics in the printing step (S150) to be described later, thereby improving the various characteristics of the ceramic glass finally produced in the present invention, which will be described later.

FIG. 3 is a schematic view illustrating a step of preparing a ceramic ink mixture in the method of manufacturing a ceramic glass using the nano-microstructure of FIG.

3, the ceramic ink mixture preparing step S140 is a step of preparing a ceramic ink mixture to be printed on the surface of the glass substrate. The mixing step S141, the stirring step S142, and the aging step S143 ).

The mixing step (S141) is a step of blending various materials contained in the ceramic ink mixture. In this embodiment, the ceramic ink, the special mineral and the special oil are mixed with each other to prepare a blend liquid.

On the other hand, the printing step described below proceeds in two steps in total, and each step proceeds under different conditions. At this time, the ceramic ink mixture used in each step constituting the printing step (S150) is also made to have different characteristics. In summary, in the present ceramic ink mixture step, a total of two types of ceramic ink mixture liquids are prepared corresponding to the printing step (S150).

More specifically, in the printing step (S150) to be described later, a high-temperature ceramic ink mixture having high-temperature heat resistance characteristics and a low-temperature ceramic ink mixture having a lower heat-resistant temperature than the high-temperature ceramic ink mixture are used. Therefore, in this step, the high-temperature ceramic ink and the low-temperature ceramic ink are separately mixed to produce a total of two types of ceramic ink mixture. The use of each ceramic ink mixture will be described later.

The stirring step (S142) is a step of stirring the compounding liquid containing various materials in the above-described mixing step (S141) under predetermined conditions.

This step will be described in more detail. The mixing liquid is stirred and the atmosphere is repeated at a time interval of 30 minutes. That is, after the compounding liquid is stirred at a constant rate over 5 to 10 times, it waits for no further agitation. After 30 minutes to 1 hour, the stirring of the above-described form is restarted and the stirring is continued after a certain number of agitations. This cycle is repeated 10 to 12 times by repeating such stirring, atmospheric, re-stirring, and atmospheric conditions. However, the time interval between agitation and re-agitation and the total agitation number are not limited to the above-mentioned contents.

As described above, stirring and air are repeated to uniformly disperse the different particles in the compounding liquid, thereby improving mixing uniformity.

The aging step (S143) is a step of aging the blended solution having been stirred to finally produce the ceramic ink mixed solution.

In this step, the mixed liquid in a state where the stirring is completed is aged for a certain period of time to finally complete the ceramic ink mixed solution. The ceramic ink mixture prepared by the mixing, stirring, atmospheric, and aging processes described above is easily fused to the glass substrate in the printing step (S150) to be described later, and as a result, the bonding and durability are remarkably improved It is.

On the other hand, though it is not limited, it is most preferable that the compounding solution which is repeatedly stirred in this embodiment is aged for about two days.

As described above, a total of two types of ceramic ink mixture liquids, that is, a mixture of high-temperature ceramic ink and low-temperature ceramic ink, are produced through this step.

The printing step S150 is a step of printing the ceramic ink mixture on the glass substrate, and printing is performed in two steps of different conditions, which are referred to as a first step S151 and a second step S152, respectively . Hereinafter, each step constituting the printing step S150 will be described in detail.

The first step S150 is a step of printing a mixture of high-temperature ceramic ink on the surface of the glass using a silk screen printing method. Silk screen printing is a printing method in which a pressure is applied using a predetermined pressurizing device such as a roller in a state in which a print is in contact with an object on an object.

More specifically, this step is performed at a higher temperature than the second-step temperature condition described later. That is, a high temperature ceramic ink mixed liquid is printed on a glass surface by a silk screen printing method at a temperature of approximately 700 ° C.

In this process, the ceramic ink mixed liquid is pressurized toward the surface of the glass by the silk screen method, and this pressing force is simultaneously applied to the ceramic ink mixture, the glass substrate, and the staple remaining on the glass substrate. By the pressing force of the silk screen printing method, the ceramic ink mixed solution is printed on the surface of the glass substrate while being fused with the staple fibers.

Specifically, the ceramic ink mixture, the ceramic contained in the glass substrate, and silicon react with the staple fibers remaining in the fine grooves of the glass substrate and fuse with each other by the heat applied for the high-temperature temperature condition and the pressure of the silk screen printing method .

By the fusion reaction between the ceramics, silicon, and gold stones, the ceramic ink can be printed on the surface of the glass substrate in a more rigid state. In addition, the light reflection rate of the surface of the glass substrate is decreased after the ceramic ink mixture is printed by the fusion reaction described above, and the hardness is increased as a whole.

When the silk screen printing is completed as described above, the printed high-temperature ceramic ink mixture is dried by forcibly circulating air having a relatively low temperature of about 180 DEG C in the chamber containing the glass substrate.

When the drying is completed as described above, the fan is operated to cool down the temperature rapidly.

When the first step S151 is completed, the second step S152 is performed. In the first step S151, the glass substrate for high-temperature ceramic ink mixture is printed on the glass substrate R And the low temperature ceramic ink mixture is printed again.

In this step, a low temperature ceramic ink mixed liquid is printed on a glass substrate using a silk screen printing method at a temperature of about 630 ° C.

When the silk screen printing is completed as described above, the low-temperature ceramic ink mixture is dried by forcibly circulating air having a relatively low temperature of about 180 DEG C in the chamber containing the glass substrate.

When the drying is completed as described above, the fan is operated to cool down the temperature rapidly.

FIG. 4 is a cross-sectional view of a ceramic glass manufactured by the method of manufacturing a ceramic glass using the nano-microstructure of FIG.

4, in the first step S151, the high-temperature ceramic ink mixture 30 having a relatively high temperature heat resistance characteristic is directly printed on the surface of the glass substrate 20, and in the second step S152, The double-layer printing is performed by re-printing the low-temperature ceramic ink mixture 40 having a relatively low heat resistance characteristic, thereby improving physical durability as a whole and improving the durability of the ceramic ink mixture 40 There is an advantage in that the surface of the glass substrate 20 is protected by the high-temperature ceramic ink mixture 30 which is more durable even when the damage is applied. In addition, as compared with the case where only the high-temperature ceramic ink mixture 30 is printed in multiple, there is an advantage that the production cost is reduced as a whole by printing the two types of ceramic ink mixture in stages.

The strengthening step (S160) is a step of cooling the glass substrate on which the ceramic ink mixture is printed after heating, and the overall durability can be improved by going through this step.
