Description

FIELD OF THE INVENTION [0001] The present invention relates to a method of attaching a decorative piece to a surface of a transparent body,

The present invention relates to a method of attaching a decorative piece to a surface of a glass or plastic transparent body, more specifically, to a decorative pattern formed by UV curable ink, a plurality of decorative pieces can be easily attached, To the surface of the decorative piece.

In general, printing is a process of copying letters or pictures in a mechanical or chemical way onto the surface of paper, cloth or other objects. Currently, printing is performed by using color printing, letterpress printing, rotogravure, offset, letter set, silk screen printing, , Electrostatic printing, and the like.

Recently, the development of printing technology has been developed so that printing can be directly performed on objects having relatively high surface roughness such as tempered glass and plastic.

More specifically, screen printing or transfer printing using a transfer sheet is used as a specific printing method when printing directly on an object having a high surface roughness.

In the screen printing method, there is no restriction on the pattern development and size. However, since printing is performed within 4 degrees due to the nature of silkscreen printing, it is difficult to apply complicated patterns, and the working process is difficult and mass production is difficult It is rarely applied except for some special cases.

Further, in the transfer printing method, a pretreatment step is required to ensure good thermal transfer of the printed pattern, and a back coating layer for improving the hiding power is additionally required under the transfer printing layer. When a glass plate is used as a transparent plate in this method, the transfer film for glass is not produced domestically and the entire amount of the film is dependent on the import, the pattern of the transfer film is limited, and it is difficult to develop a separate pattern.

In addition, there is a problem in the production of a large size to be applied to a home appliance or an interior. In addition, when the thickness of the transfer printing layer is thin, scratches on the printing layer are liable to be damaged due to surface scratches during the handling process, and there is a high possibility of failure in the production process and a transparent glass plate in which the pre- There is a problem that the surface of the transfer printing layer is likely to be peeled off and discolored, resulting in poor quality stability.

In addition, spray paints for achieving solid color or metallic effect are inexpensive, but there are many defects caused by problems such as stain or discoloration of paints for paints, and there is a problem in that a transparent plastic material such as an acrylic plate or a polycarbonate plate When used in place of substitution, problems such as staining and swelling may occur due to chemical properties.

In recent years, a lot of reinforced glass has been used so that users can enjoy their eyes and enjoy the beauty of electronic products such as refrigerators and air conditioners. In such a tempered glass, patterns or characters of various colors are printed.

Thus, it has been a primary concern of those skilled in the art to have the pattern of the glyph or character represented on the tempered glass be more clearly revealed.

1 is a flow chart illustrating a method for perl mixing printing on a tempered glass surface according to the prior art.

As shown in Fig. 1, a method for performing perlite blending printing on a conventional tempered glass surface comprises the steps of (S1) applying ink to print a pattern of characters or characters on the surface of the tempered glass, (S2) of applying a transparent ink mixed with pearl (also referred to as a " glitter ") in a state in which the pearl mixed ink is dried ).

Fig. 2 is a cross-sectional view showing a printed product produced by a method for perl mixing printing on a glass surface according to the prior art.

As shown in Fig. 2, the printed matter 1 produced by the method for perl mixing printing on a glass surface according to the prior art has a structure in which an ink layer (not shown) A transparent ink layer 4 for protecting and hiding the ink layer 3 and an identification ink layer 5 for facilitating identification of the pattern or character pattern.

However, the conventional method for performing the pearl mixed printing on the glass surface is difficult because it is difficult to firmly adhere the ink to the tempered glass having a high surface roughness because the ink for forming patterns of patterns or characters is directly applied to the tempered glass There was a problem.

The printed matter produced by the method for perl mixing printing on the glass surface according to the prior art has a problem in that it is difficult for the user to clearly identify the pattern or the character because the pattern of the pattern or character is not clear and the three- .

In addition, since the ink layer is not firmly adhered to the tempered glass, the pattern produced by the method for perl mixing printing on the glass surface according to the prior art is difficult to keep for a long time or a pattern of letters, The pattern can be expressed only in a simple planar pattern, and the three-dimensional pattern can not be expressed properly, so that the expression and the beauty of the pattern are deteriorated.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a transparent body capable of easily forming a pattern of characters or characters using a conventional apparatus such as a digital UV printer on the surface of glass or plastic having excellent surface roughness, And a method for attaching a decorative piece to a surface.

According to an embodiment of the present invention, there is provided an ink applying method comprising: an ink applying step of applying a UV curable ink to a surface of a transparent body so that the transparent body has a decorative pattern; There is provided a method of attaching a decorative piece to a surface of a transparent body including a decorative piece applying step of applying a decorative piece and an ultraviolet light irradiation step of irradiating the transparent body with ultraviolet light.

According to the present invention, since a decorative piece and UV curable ink are not mixed and used in advance, a pattern of a decorative pattern can be formed on a transparent body by using a conventional apparatus such as a digital UV printer. That is, in order to use a mixture of a decorative piece and a UV curable ink, a digital UV printer having nozzles of a print head having a size such that a decorative pattern is manually formed in a transparent body or a size through which a decorative piece is passed must be newly purchased, Since the present invention can use an existing apparatus, the working time is shortened and a clear decoration pattern can be formed.

Further, since the present invention does not require premixing of the decorative pieces and the UV curable ink, it is convenient to store the unused materials after the work, and the cost is reduced because waste which is difficult to recycle is not generated.

In addition, since the exterior of the ornamental pattern is clearly displayed, the present invention can express the pattern to be expressed more stereoscopically. Since the UV curable ink having a high surface roughness is first applied to the transparent body having a high surface roughness, the UV curable ink is sprayed with a decorative piece, and then the UV curable ink is irradiated. Therefore, Can be easily removed.

Further, the present invention can easily attach different types of decorative pieces to the UV curable ink applied to the transparent body, so that delicate expressions are possible and the degree of freedom of design is high.

3 is a flowchart for explaining an embodiment of a method of attaching the decorative piece 30 according to the present invention.

Referring to FIG. 3, a method of attaching a decorative piece according to the present invention includes applying an ink applying step (S100) for applying UV curable ink, a decorative piece applying step (S200) for applying a decorative piece, And irradiating ultraviolet light (S300).

Hereinafter, each component will be described in more detail with reference to the drawings.

4 is a cross-sectional view showing a printed matter produced by a method of attaching a decorative piece according to the present invention.

Referring to FIG. 3, a method of attaching a decorative piece according to the present invention includes an ink application step (S100).

The ink applying step S100 is a step of applying a UV curable ink to the surface of the transparent body so that the transparent body has a decorative pattern. The decorative pattern formed by the UV curable ink has a texture to the transparent body 10 To provide a three-dimensional beauty.

Since the decorative piece 30 is not mixed with the UV curable ink 20, the ink applying step S100 can use existing equipment such as a digital UV printer. In other words, when the decorative piece 30 is mixed with the UV curable ink 20, the print head nozzle of the digital UV printer can not pass the decorative piece 30, so that the existing equipment can not be used, In the applying step S100, since the decorative piece 30 is applied to the transparent body 10 in a state that the decorative piece 30 is not included in the UV curable ink 20, existing equipment can be used.

As described above, in the prior art, since the decorative piece 30 is applied to the transparent body 10 while being mixed with the UV curable ink 20, in order to form a specific decorative pattern on the transparent body 10, Since the ink 20 is applied, it takes a long time in the ink applying step S100 and the decoration pattern is not clear due to the limitation of the manual operation. However, the present invention is applicable to a conventional apparatus such as a digital UV printer The decorative pattern required by the user can be simply printed on the transparent body 10, and the decorative pattern has the effect of displaying a clear line.

Here, as the transparent body 10, any one of glass having high surface roughness, tempered glass, and plastic can be used. At this time, the plastic is made of any one of poly methly methacrylate (PMMA), polytetrafluoroethylene (PTFE), and polycarbonate (PC), which satisfy both transparency and durability in various synthetic resins Can be selected and manufactured. Herein, the tempered glass means a glass which is heated by 500 to 600 ° C and quenched with compressed cooling air to cause compression deformation on the glass surface portion, and tensile deformation of the glass surface portion.

The UV curable ink 20 is an ink that is cured and dried in a liquid phase to a solid state by causing a photochemical reaction with ultraviolet energy (100 to 400 nm). The ink can be instantly cured according to the instantaneous irradiation of ultraviolet rays, Lt; / RTI >

In addition, since the UV curable ink 20 has a short curing time and is improved in workability and is made of 100% solids free from volatile organic solvent, it is possible to prevent pollution and curing at a low temperature, ) Can be easily applied. In addition, there is no discoloration on the work, and continuous operation is possible. There is no odor of the printed matter, no back hiding and blocking, less yellowing, and excellent resistance to abrasion, heat resistance, solvent and chemicals.

The UV curable ink 20 includes a photopolymerization initiator, a photopolymerizable resin, an organic solvent, and the like. Specifically, the UV curable ink 20 is composed of a photopolymerizable resin, a photopolymerization initiator, an organic solvent, a pigment, an auxiliary agent, a polymerization inhibitor, and a drying inhibitor.

As the photopolymerizable resin, an ultraviolet ray reaction type acrylic or vinyl monomer may be used.

The photopolymerization initiator generates a radical from ultraviolet rays, which reacts with the monomer to cause polymerization. Such photopolymerization initiators include carbonyl compounds, sulfur compounds, azo chemicals, and organic and inorganic compounds, and carbonyl compounds are mainly used.

The pigment is selected and used because it inhibits the action of forming a film or has poor storage stability.

Various additives such as a viscosifying agent, an antioxidant, a wetting agent, a dispersant, a stabilizer, and a wax are used as the adjuvant, and the wax serves as a coating enhancer of the coating film.

The polymerization inhibitor is added in a small amount to prevent dark reaction of the UV curable ink 20, and the storage stability is improved.

Preferably, a transparent varnish is used as the UV curable ink 20 according to the present invention, and the color is a transparent color.

As described above, the UV curable ink 20 can provide an improved aesthetic by imparting a texture to the surface of the transparent body 10, unlike a glass coating agent or an adhesive that merely imparts an adhesive force, and hardened within a few seconds through ultraviolet irradiation, Even with a solid line, a clear line can be maintained so that the user can clearly identify the decorative pattern.

5 is a flowchart for explaining another embodiment of a method for attaching a decorative piece according to the present invention.

Referring to FIG. 5, the method of attaching a decorative piece according to the present invention may further include a background pattern forming step (S50) before the ink applying step.

The background pattern forming step (S50) is a step of applying a UV curable ink having a color pigment added thereto to a transparent body in a predetermined pattern, and irradiating ultraviolet rays to cure the predetermined pattern to form a background pattern.

For example, as shown in FIG. 6, the background pattern forms a leaf pattern providing a decorative pattern formed in a flower shape and serves to highlight the beauty of the decorative pattern.

At this time, in the background pattern forming step, a predetermined pattern is printed on the transparent body 10 with the UV curable ink 20 using existing equipment such as a digital UV printer, and then the UV curable ink 20 is cured.

Referring to FIG. 3, a method of attaching a decorative piece according to the present invention includes a decorative piece applying step (S200).

The decorative piece application step S200 is a step of applying the decorative piece 30 to the surface of the transparent body 10 to which the UV curable ink 20 is applied through the ink applying step S100, Is applied to the surface of the transparent body 10 by hand or applied to the surface of the transparent body 10 through spraying.

The decorative piece 30 applied to the surface of the transparent body 10 in this step S200 is brought into contact with the UV curable ink 20 applied to the surface of the transparent body 10 through the ink application step S100, The ink 20 is seated on the surface of the transparent body 10 to which the ink 20 is not applied.

As the decorative piece 30, a synthetic resin powder, a metal powder, a pearl powder, a stone powder, a sequin, a hot piece, a rhinestone, a stone piece or a mixture thereof may be used.

Referring to FIG. 3, a method of adhering a decorative piece according to the present invention includes an ultraviolet ray irradiation step (S300).

The ultraviolet ray irradiation step S300 is a step of irradiating ultraviolet rays to the transparent body 10 which has passed through the decorative piece applying step S200, and the ultraviolet ray irradiation is performed in a range of 1 to 10 seconds.

In this step S300, the UV curable ink 20 in contact with the decorative piece 30 is cured by ultraviolet irradiation to fix the decorative piece 30 to the UV curable ink 20.

The ultraviolet ray irradiation may be changed depending on the type of the decorative piece 30. More specifically, when only a synthetic resin powder, a metal powder, a pearl powder, a stone powder, or a mixture thereof is used as the decorative piece 30, it has an irradiation time ranging from 1 to 5 seconds. When a mixture of a powder such as a synthetic resin powder, a metal powder, a pearl powder, a stone powder, and a sequin, a hot piece, a rhinestone, and a stone piece is used as the decorative piece 30, the irradiation time is in the range of 3 to 7 seconds. In addition, when only the mixture of sequins, hot peas, rhinestone and stone pieces is used as the decorative piece 30, it has an irradiation time ranging from 5 seconds to 10 seconds. The UV irradiation time required for the UV curable ink 20 to fix the sequin, the hot piece, the rhinestone, and the stone piece to the UV curable ink 20 is less than that of the UV curable ink 20 because the volume of the sequin, This is because a time longer than the ultraviolet ray irradiation time required for the UV curable ink 20 for fixing the powder to the UV curable ink 20 is required. That is, when the ultraviolet ray irradiation time is below the lower limit, the decorative piece 30 may be detached from the transparent body 10 as the use period elapses.

Referring to FIG. 5, the method of attaching a decorative piece according to the present invention may further include a cleaning step S400 after the ultraviolet ray irradiation step S300.

The cleaning step S400 is a step of washing the transparent body 10 to remove the decorative piece 30 applied in addition to the UV curable ink 20 from the surface of the transparent body 10 and remove the liquid such as water have.

If the surface of the transparent body 10 is cleaned by using a liquid such as water in this step S400, the decorative piece 30 applied in addition to the UV curable ink 20 is not fixed to the transparent body 10, 10 smoothly.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention as defined in the appended claims. It can be understood that it is possible.
