In general, glass is applied in a variety of ways, such as glass for interior and exterior walls, glass for interior decoration, and glass for doors or windows. Recently, a 3D and three-dimensional atmosphere has been added to glass to create a more beautiful and highly decorative interior atmosphere.

As a related glass plate technology, Korea Patent Registration No. 10-1963540 (Prior Patent 1) introduces 'decorative glass panel and its manufacturing method'. In the decorative glass panel of Prior Patent 1, a dot pattern and a dot pattern are formed on both sides of the glass, and an optical illusion between them is used to create a three-dimensional effect.

In addition, Korean Registered Patent No. 10-2290886 (Prior Patent 2) introduces a 'method for manufacturing opaque plate glass having a color pattern'. In the opaque plate glass of Prior Patent 2, after forming a base layer and a pattern layer on a glass substrate, the base layer and the pattern layer are fused to the surface of the glass substrate by high-temperature heat treatment, and at the same time, micropores are formed, and micropores are eroded by etching. A method for manufacturing a plate glass having a three-dimensional effect is introduced.

However, the opaque plate glass of Prior Patent 1 is also manufactured in a way of forming a pattern through repetitive printing and etching processes, and the manufacturing process is complicated, and many foreign substances are generated after the process and the use of chemicals, causing problems of contaminating the surrounding environment. there is.

Referring to FIG. 1 , in the glass sheet material 100 of this embodiment, a pattern film 130 having a three-dimensional pattern 131 transferred to the surface of the glass sheet 110 is bonded through an adhesive film 120 .

The plate glass 110 may be made of glass of a transparent material having a predetermined thickness and area, and the adhesive film 120 is made of a hot melting film of a transparent material. For example, the adhesive film 120 may be composed of an ethylene vinyl acetate (EVA) film or a polyamide (PA) film.

The pattern film 130 is a configuration for designing a 3D three-dimensional shape on the surface of the plate glass 110, and may be composed of a transparent film made of a plastic material. The pattern film 130 is adhered to the surface of the glass plate 110 via the adhesive film 120, and a 3D three-dimensional pattern 131 is formed on the surface. The three-dimensional pattern 131 may be formed by being transferred from a separate pattern plate 20 . The pattern film 130 may be bonded to one side or both sides of the plate glass 110 .

Hereinafter, a process of manufacturing a glass plate material having a three-dimensional pattern on the surface of the present embodiment will be described.

Figure 2 is a cross-sectional view showing a laminated structure for the main configuration of the process of manufacturing a glass sheet according to the present embodiment, Figure 3 is a flow chart showing the process of manufacturing a glass sheet according to the present embodiment, Figures 4 and 5 is a diagram showing a vacuum compression process and a thermal bonding process of the glass plate according to the present embodiment.

Referring to FIGS. 2 and 3 , in the glass sheet material 100 of this embodiment, a sheet glass 110 constituting the glass sheet material, an adhesive film 120, and a pattern film 130 are sequentially laminated on a base plate 10. And, the pattern plate 20 for transferring the 3D three-dimensional pattern and the buffer film 30 are laminated on top of the pattern film 130, respectively. The pattern film 130 is composed of a film having a predetermined thickness before the three-dimensional pattern 131 is transferred, and the three-dimensional pattern 21 of the pattern plate 20 is transferred to the pattern film 130 .

The base plate 10 is configured to seat each component, and is composed of a plate of material having a predetermined thickness and sufficient rigidity to safely protect the components even in a vacuum state.

The pattern plate 20 is configured to transfer a 3D three-dimensional pattern to the pattern film 130, and for this purpose, the original 3D three-dimensional pattern 21 is formed on the lower surface in contact with the pattern film 130. The three-dimensional pattern 21 may have various shapes such as a concavo-convex shape and a wavy shape. The pattern plate 20 is made of a material having sufficient heat resistance and pressure resistance because the shape of the pattern must be maintained under high temperature and high pressure.

The buffer film 30 has a configuration such that uniform pressure is applied to the entire area of the pattern plate 20 and is laminated on the entire area of the upper surface of the pattern plate 20 .

When the pattern plate 20 is pressed against the pattern film 130 using the vacuum compression device 40 , vacuum pressure may not be uniformly applied to each region of the pattern plate 20 . In this case, the transfer rate of the three-dimensional pattern 131 transferred to the pattern film 130 may vary according to the position of the pattern plate 20 . The buffer film 30 is laminated to prevent this, and the vacuum pressure applies a uniform pressure to the pattern plate 20 so that the three-dimensional pattern is uniformly transferred. The buffer film 30 for this is made of a material having a predetermined elasticity, and may be made of, for example, a silicon film.

In addition, when vacuum pressure is instantaneously applied to the pattern plate 20, the buffer film 30 buffers the pattern film 130 so that the vacuum pressure is gradually transmitted. When the vacuum pressure instantaneously applied to the pattern plate 20 is transferred to the pattern film 130 as it is, the transfer efficiency of the three-dimensional pattern 21 and the accuracy of the pattern may deteriorate. Accordingly, the buffer film 30 improves the transfer efficiency by allowing the three-dimensional pattern 21 to be accurately transferred.

Looking at the process of manufacturing a glass plate material using the components as described above in detail, first, the plate glass 110 is prepared and the surface is modified (S11). Surface modification is a process of surface treatment to improve bonding strength of the pattern film 130, and is performed by irradiating UV light to the surface of the plate glass 110 to which the pattern film 130 is to be bonded. That is, the prepared sheet glass 110 is placed on a jig (50 in FIG. 4) before the adhesive film 120 and the pattern film 130 are laminated, and light is irradiated with a UV lamp to remove fine foreign substances or moisture remaining on the surface. remove enough

Then, as shown in FIG. 4, each component is sequentially stacked on the vacuum pressing device 40 on the jig 50 (S12). In the vacuum compression device 40, the upper and lower frames 41 and 42 are coupled to be opened and closed based on a hinge axis on one side, and the lower frame 41 is provided with a lower plate 44 in which a vacuum hole 46 is formed. , The upper frame 42 is provided with a cover film 45. The cover film 45 is configured to elastically press each component in a vacuum state, and may be composed of a PET (Polyester) film.

The base plate 10, the plate glass 110, the adhesive film 120, the pattern film 130, the pattern plate 20 and the buffer film 30 are sequentially applied to the lower plate 44 of the vacuum compression device 40. After stacking, when the driving motor 51 of the jig 50 operates in a state in which the upper frame 42 is closed and the inner space of the upper and lower frames 41 and 42 is vacuumed, the cover film 45 vacuums each component. It is pressurized (S13). Therefore, the base plate 10, the plate glass 110, the adhesive film 120, the pattern film 130, the pattern plate 20, and the buffer film 30 are in close contact with each other by vacuum, forming one laminate 200. will achieve

At this time, the pattern plate 20 presses the pattern film 130 with strong pressure so that the three-dimensional pattern 21 formed on the pattern plate 20 can be transferred to the pattern film 130 .

Then, as shown in FIG. 5, in a state where the components are vacuum-compressed, the vacuum-compressed assembly is put into the thermal bonding chamber 60 and bonded with high-temperature heat (S14). At this time, the vacuum compression assembly maintains a vacuum state. In the thermal bonding process, the pattern film 130 is adhered to the plate glass 110 by the adhesive film 120, and at the same time, the three-dimensional pattern 21 of the pattern plate 20 is completely transferred to the pattern film 130.

An ultraviolet heater may be used as a heat source in the thermal bonding process, and the thermal bonding process is performed in the thermal bonding chamber 60 blocked from the outside according to predetermined temperature and time conditions. The temperature and operation time may be determined according to the characteristics of the adhesive film 120, and the EVA film is made at a temperature of 85° C. for about 20 minutes in the case of a 0.25 mm thick film and about 30 minutes in the case of a 0.5 mm thick film. In addition, when the adhesive film 120 is a PA film having a thickness of 0.25 mm, it is performed at a temperature of 130° C. for about 20 minutes.

When the laminate 200 is formed by the thermal bonding process, the vacuum compression assembly is taken out of the chamber 60 and the adhesive film 120 is cured (S15). In the curing process of the adhesive film 120, since peeling may occur on the bonding surface due to the cooling rate of the different materials, in order to prevent this, it is preferable to proceed in an environment where the temperature is gradually lowered as much as possible, and until complete curing is achieved. keep a vacuum

After the adhesive film 120 is completely cured, the vacuum state is released to separate the glass sheet material 100 (S16). The release of the vacuum state is performed when the temperature of the vacuum compression assembly is checked and confirmed to be the same as the temperature in the workshop. Since the glass sheet 100 may be peeled off or the three-dimensional pattern may be damaged during the separation process, it is preferable to separate the glass sheet 100 after 24 hours have elapsed after releasing the vacuum to prevent this.

The separated glass plate 100 is used after being cut to the required standard (S17).

As such, the glass sheet material of this embodiment can impart a three-dimensional pattern to the surface of the glass sheet by using an adhesive film, a pattern film, and a pattern plate, and a uniform three-dimensional pattern can be formed over the entire area of the glass sheet by using a buffer film in the vacuum adsorption process. can form In addition, since the glass plate material of this embodiment can be manufactured by vacuum pressing and thermal bonding processes, there is an effect of simplifying the manufacturing process.

Therefore, according to the manufacturing method of this embodiment, two glass plate materials 100 can be manufactured by one vacuum compression process and a heat bonding process.

And, referring to FIG. 7 , in this embodiment, the functional film is further combined so that the glass sheet 100 can exhibit various functions or decorations.
