As shown in Figures 1 to 5, the gold leaf printed matter manufacturing method 100 is a method of manufacturing a gold leaf printed material by adhering gold leaf 350 to a base plate 300, and an image is attached to the bottom of the self-heating pressing plate 200. A printing step of printing a layer (S100), a processing step of improving adhesion by processing the upper surface of the base plate 300 (S120), and a gold foil 350 between the pressing plate 200 and the base plate 300. It includes a gold foil adhesion step (S140) of thermo-compressing the gold foil 350 on the upper surface of the base plate 300 with the image layer heated by the compression plate 200 in the arranged state.

Specifically, in the printing step (S100), the pressing plate 200 is a PTC heater (Positivetemperature coefficient Heater) that is connected to an external power source and capable of self-heating and is formed in the shape of a plate, and the bottom of the pressing plate 200 It is placed in the internal space 442 of the storage member 440 of the spin unit 400 so that it faces upward (step S100).

With the bottom of the press plate 200 facing upward, the upper surface of the press plate 200 is in close contact with the bottom surface of the storage member 440 in the internal space 442, and the front, back, and Each of one side and the other side is in close contact with the inner surfaces corresponding to the front, rear, one side, and the other side of the storage member 440 (step S100).

A metal particle solution 320 consisting of a plurality of metal particles, a solvent, a linear polymer, and a dispersant is injected into the interior of the storage member 440 and applied to the bottom surface of the pressing plate 200, and the spin unit 400 is driven. By rotating the pressing plate 200, the metal particle solution 320 is adhered to the bottom of the pressing plate 200 at a uniform thickness (step S100).

The solvent included in the metal particle solution 320 may be water or an organic solvent, and the linear polymer increases the stability and dispersibility of the metal particles and prevents aggregation of the metal particles (step S100).

The dispersant functions to reduce the growth of metal particles and prevent the three-dimensional bonding of inorganic metal particles and organic linear polymers, and is used in polyoxyethylene alkyl ether, polyoxyethylene fatty acid ester, and polyoxyethylene alkyl ether. One or more (one type or a mixture of two or more types) selected from ethylene alkyl phenol ether, sorbitan fatty acid ester, polyoxyethyl sorbitan fatty acid ester, and sucrose fatty acid ester can be used (step S100).

The metal particle solution 320 preferably has a relatively high specific gravity of metal particles so that it can be easily processed into the image layer 340 by a laser 620, which will be described later, and contains 20 parts by weight of metal particles, 5 parts by weight of linear polymer, and a dispersant. It consists of 5 parts by weight and 70 parts by weight of solvent (step S100).

The metal particle solution 320 is irradiated with ultrasonic waves in the process of stirring the metal particles, linear polymer, and dispersant, and the ultrasonic waves are irradiated to the metal particle solution 320 by driving the storage member 440, which will be described later. (Step S100).

As shown in FIG. 2, the spin unit 400 includes a motor 410, supports 420, a case 430, and a storage member 440 (step S100).

The spin unit 400 is formed so that the storage member 440 disposed inside the case 430 rotates about the upper and lower axes, and the pressing plate 200 and the metal particle solution 320 are formed by driving the spin unit 400. It is rotated inside the storage member 440 (step S100).

The motor 410 is formed in the form of a cylinder extending upward and downward and is placed in the lower part of the case 430, and in the center of the upper part, a drive shaft in the form of a cylinder extending upward and downward extends upward, penetrates the case 430, and is then stored. It is coupled to the bottom of the member 440 (step S100).

One end of each of the supports 420 is formed in a cylindrical shape extending upward and downward, and the upper end is positioned on the bottom of the case 430 while being spaced apart at a predetermined distance along the edge of the case 430. surface bonding (step S100).

The other end of each of the supports 420 extends a predetermined distance toward the bottom while maintaining a cylindrical shape at one end, so that the bottom of the other end is in close contact with the floor, and a rubber pad may be attached to the bottom of the other end of each of the supports 420. There is (step S100).

The case 430 is formed in the form of a container in which the internal cylindrical rotation space 432 is open toward the top, and provides a space in which the storage member 440 disposed therein is rotated (step S100).

A portion of the center of the bottom surface corresponding to the lower part of the rotation space 432 of the case 430 is depressed toward the bottom to form a hole, and the drive shaft of the motor 410 protrudes into the rotation space 432 through the hole ( Step S100).

The storage member 440 is formed in the form of a square container with a hexahedral internal space 442 open toward the top, and when inserted into the rotation space 432, the center of the bottom is coupled with the drive shaft of the motor 410 to form a motor. It rotates forward or backward according to the driving of 410 (step S100).

The upper surface of the outer wall located on the front, rear, one side, and other side of the storage member 440 is more exposed than the metal particle solution 320 when the pressing plate 200 and the metal particle solution 320 are stored in the internal space 442. It is manufactured to be located on a high horizontal line (step S100).

Inside the outer walls corresponding to the rear, front, one side, and other sides of the storage member 440, a side vibrator 444 in the form of a plate is oriented with a relatively large surface area toward the internal space 442 and the metal particle solution 320. is inserted (step S100).

Each of the side vibrators 444 is inserted to be positioned on the same horizontal line as the metal particle solution 320 inside the rear, front, one side, and other sides of the storage member 440 (step S100).

The ultrasonic waves generated from the side vibrators 444 disperse the metal particles dispersed in an outward direction by the rotation of the storage member 440 toward the center of the internal space 442, so that the metal particles are contained within the metal particle solution 320. Ensure that it is placed with a uniform thickness (step S100).

With the metal particle solution 320 uniformly applied to the bottom of the pressing plate 200, the plate-shaped diffusion plate 500 is inserted into the internal space 442 and placed on top of the metal particle solution 320 ( Step S100).

With the diffusion plate 500 inserted into the internal space 442, the laser 620 of the laser unit 600 is irradiated from the top of the diffusion plate 500 through the diffusion plate 500 to the metal particle solution 320. If so, some of the plurality of metal particles heated by the laser 620 are melted and combined to form the image layer 340 (step S100).

Meanwhile, in order to print relatively finer gold foil 350, the diffusion plate 500 may be excluded and the laser 620 may be irradiated with the metal particle solution 320 (step S100).

The diffusion plate 500 is a member that functions as a lens made of transparent material that diffuses the laser 620 irradiated with the metal particle solution 320. The laser 620 penetrating the diffusion plate 500 is divided into relatively large numbers. The metal particles are melted, thereby processing a relatively thick image layer 340 (step S100).

As shown in FIGS. 2 and 3, the laser unit 600 includes a laser module 610 and a laser 620.

The laser module 610 is connected to a rail module for a 3D printer that moves along a rail in the X-axis or Y-axis, which are perpendicular to each other, at the top of the spin unit 400, and is formed to be moved to various positions, and can be connected to a terminal or smartphone. It is connected to and allows the worker to move according to the desired image (step S100).

The laser module 610 and the laser 620 are moved by the rail module for the 3D printer along the border of the image designed by the operator, and a plurality of metal particles melted by the laser 620 are melted and combined with each other to create the An image layer 340 having the shape of an image is formed (step S100).

Therefore, the image layer 340 is formed on the bottom of the pressing plate 200 by a plurality of metal particles melted and combined by the laser 620, and the fine metal particles are combined with each other. (100) can adhere gold leaf (350) in a fine shape, such as a feather, to the base plate (300).

Meanwhile, as another embodiment of the printing step (S100), with the pressing plate 200 disposed in the internal space 442, the bottom of the pressing plate 200 is formed of a metal or polymer material by a metal or polymer 3D printer. The image layer 340 can be attached to the bottom of the pressing plate 200.

At this time, the polymer used in the polymer 3D printer is preferably a heat-resistant polymer that does not deform even at a temperature higher than the temperature of the pressing plate 200, which is heated to adhere the gold foil 350 to the base plate 300.

Meanwhile, the metal 3D printer and the polymer 3D printer are connected to the rail module for the 3D printer in the same way as the laser unit 600 and can automatically move to various locations, and the operator can operate the laser unit 600 through terminal control. Instead, either the metal 3D printer or the polymer 3D printer can be moved to the upper part of the spin unit 400.

In the processing step (S120), the upper surface of the base plate 300 is processed to be matte, but anodized to improve adhesion with the gold foil 350, and the base plate 300 is made of any one of glass, crystal, or transparent polymer material. When used as a transparent material, the metal particle solution 320 used in the printing step (S100) is used for matte processing of the base plate 300.

As shown in FIG. 4, in the first embodiment of the processing step (S120), when the base plate 300 is used as the transparent material, the spin portion 800 is used to improve adhesion with the gold foil 350. The upper surface of the transparent material is matted through (step S120).

Since the spin unit 800 is substantially the same as the spin unit 400 used in the printing step (S100) except for the storage member 448, the motor 410, supports 420, and case 430 are The same reference numbers are used, and duplicate descriptions are omitted.

The spin unit 800 further includes a storage member 448 (step S120).

The storage member 448 is formed in the form of a square container with a hexahedral internal space 442 open toward the top, and the structure itself is the same as the storage member 440, but from the bottom of the storage member 448 to the outer wall. The height between the upper surfaces is formed to be relatively lower than the thickness of the base plate 300 (step S120).

The base plate 300 is inserted into the internal space 442, and the front, rear, one side and other sides of the base plate 300 are in close contact with the bottom of the storage member 448. Each side is in close contact with the inner surfaces of the front, rear, one side, and the other side of the storage member 448, and the upper surface of the base plate 300 is located on a horizontal line that is relatively higher than the upper surface of the outer wall of the storage member 448. is formed (step S120).

With the base plate 300 inserted into the internal space 442, the metal particle solution 320 is applied to the upper surface of the base plate 300, and the press plate 730 of the press unit 700 is applied to the spin unit 800. ) and brought into close contact with the surface of the metal particle solution 320 (step S120).

The pressing unit 700 includes a cylinder 710, a pressing rod 720, and a pressing plate 730.

The pressing unit 700 moves the pressing rod 720 and the pressing plate 730 toward the top or bottom by driving while placed on the upper part of the spin unit 800, thereby pressing the pressing plate 730 into the metal particle solution 320. or separate the pressure plate 730 from the metal particle solution 320 (step S120).

The pressing unit 700 is connected to the rail module for the 3D printer through a terminal or smartphone in the same manner as the laser unit 600, and is automatically moved toward various positions programmed by the operator.

Specifically, the cylinder 710 is formed as a cylindrical hydraulic or pneumatic cylinder structure extending toward the top or bottom, and moves a portion of the pressure rod 720, which moves internally up and down depending on the drive, toward the top or bottom. (step S120).

One end of the pressure rod 720 is formed in the form of a cylinder extending upward and downward and is inserted into the interior of the cylinder 710, and the other end extends downward from one end and protrudes from the bottom of the cylinder 710 (step S120). .

The pressure plate 730 is formed in the shape of a circular or square plate, and a central portion of the upper surface is combined with the bottom surface of the other end of the pressure rod 720, and is moved to the top or bottom together with the pressure rod 720 according to the operation of the cylinder 710. moves toward (step S120).

With the metal particle solution 320 applied to the upper surface of the base plate 300, the pressure plate 730 is lowered and the motor 410 is operated with the bottom of the pressure plate 730 in close contact with the metal particle solution 320. is driven to rotate the storage member 448 (step S120).

As the downward distance of the pressure plate 730 increases or decreases, the metal particles come into close contact with the upper surface of the base plate 300 and the polishing intensity of polishing the upper surface of the base plate 300 increases or decreases (step S120).

As a second example of the processing step (S120), the base plate 300 uses an aluminum plate, and the aluminum plate improves adhesion to the gold foil 350 through a separate eco-friendly anodizing treatment (step S120).

When the base plate 300 is used as an aluminum plate, the aluminum plate is anodized to improve adhesion to the gold foil 350, and a sealing agent excluding nickel is used for eco-friendly anodizing (step S120).

Meanwhile, the solution applied to the upper surface of the base plate 300 may be a polishing solution containing water and ceramic powder instead of the metal particle solution 320.

The sealing agent used for eco-friendly anodizing of the aluminum plate excludes heavy metals such as nickel and cadmium for eco-friendly anodizing, and the sealing agent includes sodium acetate, zinc acetate, and phosphate-based compounds. , naphthalene sulfonic acid-based dispersant, organic acid and the remaining amount of water.

The sealing treatment agent relates to a sealing composition for aluminum members excluding heavy metals, and a detailed description is disclosed in Korean Patent Publication No. 10-2210641 (Sealing composition for anodized aluminum members), so detailed description is omitted.

When anodizing the aluminum plate using the sealing agent, the antibacterial and pore sealing effects and chemical resistance of the oxide film layer of the aluminum plate are improved, and the adhesion between the gold foil 350 and the base plate 300 is improved.

After processing of the base plate 300 using the metal particle solution 320 or the polishing solution is completed, the metal particle solution 320 is removed from the upper surface of the base plate 300 by a separate cleaning process, and the base plate 300 ) is used in the gold foil adhesion step (S140).

Meanwhile, the spin unit 800 is used as the spin unit 400 by detaching the storage member 448 from the drive shaft of the motor 410 and attaching the storage member 440 shown in FIG. 2 to the drive shaft of the motor 410. Since this is possible, the spin unit 800 can be used to apply the metal particle solution 320 to the pressing plate 200 or to matte the base plate 300 according to the replacement of the storage members 440 and 448. there is.

In the gold foil adhesion step (S140), gold foil 350 is placed between the upper surface of the matte base plate 300 and the bottom surface of the pressing plate 200 on which the image layer 340 is formed, and the heated pressing plate 200 is lowered to adhere the gold foil 350 to the upper surface of the base plate 300 (step S140).

Specifically, the press plate 200 on which the image layer 340 is formed is separated from the storage member 440 and placed on the upper part of the base plate 300 with the bottom facing downward, and the gold foil 350 is applied to the press plate ( 200) and the base plate 300 (step S140).

Power is supplied to the pressing plate 200 connected to an external power source to heat the pressing plate 200 to a predetermined temperature to heat the image layer 340, and the pressing plate 200 is lowered to form a surface between the bottom and the bottom of the image layer 340. The closely adhered gold foil 350 is heat-compressed to the upper surface of the base plate 300 (step S140).

When the pressing plate 200 is moved upward and separated from the gold foil 350, a portion of the gold foil 350 of the same shape as the bottom of the image layer 340 is attached to the upper surface of the base plate 300, and the base plate 300 is separated from the gold foil 350. When the gold leaf 350 other than the gold leaf 350 attached to the plate 300 is removed, the step of adhering the gold leaf 350 to the upper surface of the base plate 300 is completed (step S140).

A portion of the gold leaf 350 having the same shape as the bottom of the image layer 340 is heat-compressed on the upper surface of the base plate 300 to produce a gold leaf print consisting of the base plate 300 and the gold leaf 350.

Meanwhile, in the gold foil adhesion step (S140), the upper surface of the pressing plate 200 may be attached to the bottom surface of the other end of the pressing rod 720 instead of the pressing plate 730, and the pressing plate 200 may be attached to the pressing rod 720. It is electrically connected to an external power source and a terminal.

At this time, when the operator places the gold leaf 350 on the polished base plate 300 in the storage member 448, the pressing plate 200 is automatically lowered by driving the cylinder 710 to place the gold leaf 350 on the base. It can be heat-compressed on the plate 300.

Therefore, the gold leaf print manufacturing method 100 can effectively heat-press the gold leaf 350 in a fine shape such as a feather to the base plate 300, and if it is not in a fine shape, the gold leaf print can be quickly produced using a metal or polymer 3D printer. Production is possible.

In addition, the gold foil print manufacturing method 100 has the advantage of being able to produce the image layer 340 using the metal particle solution 320 and being able to use it as a metallic polishing solution for matting the base plate 300.

In addition, the gold foil print manufacturing method 100 allows printing of the image layer 340 using the spin unit 400 in the printing step (S100), and the spin unit 800 can be completed by simply replacing the storage member 448. ), the base plate 300 can be polished, which has the advantage of reducing manufacturing costs and improving manufacturing convenience.

In addition, since the metal 3D printer, polymer 3D printer, laser unit 600, and pressurizing unit 700 are connected to the rail module for the 3D printer and can be moved to various positions, the storage member 440 is connected to the storage member 448. There is an advantage that the production of gold leaf printed matter can be controlled fully automatically, except for the operation of replacing with and inserting the base plate 300 into the internal space 442 instead of the pressing plate 200.

In addition, the storage member 440 disperses the metal particles inside the metal particle solution 320 to a uniform thickness by ultrasonic waves through a plurality of side oscillators 444 inserted into the outer wall, so that the metal particles produced by the laser 620 are dispersed to a uniform thickness. There is an advantage that the surface of the image layer 340 is processed to be flat, and the thermal compression effect of the gold foil 350 by the image layer 340 is improved.
