Description

Method for manufacturing interpenetrating mold transfer film including metal texture three-dimensional pattern

The present invention relates to a method of manufacturing a transfer mold transfer film comprising a metallic texture three-dimensional pattern. In particular, there is a technique for forming a three-dimensional pattern under the printed layer based on the state to be transferred to express a luxurious metal texture in various forms.

In general, a casing of a small electronic product such as a mobile phone is injection-molded with a synthetic resin to form an ultraviolet (UV) coating on the surface of a molded product such as the above-mentioned mobile phone case for protection or aesthetic appearance.

In recent years, a keyboard of a hand-held terminal or a panel of a liquid crystal display (LCD) liquid crystal panel is made of a metal having a good durability, and a surface of a keyboard or a panel such as a metal material is used. In order to add a decorative aesthetic, a tiny thin line pattern is formed to play the decorative effect.

According to a conventional method, a thin wire is formed on a surface of a metal keyboard or a metal edging, and is formed by rubbing a plurality of times with a steel brush. However, the use of a steel brush to form a thin wire requires careful polishing of the surface of the product, so that the operation is very cumbersome, and there is a problem that the workability such as the metal layer is difficult to be polished even if a steel brush is used. Moreover, the dust generated when the metal layer is polished adheres to the surface of the product, which increases the rate of defective products. Therefore, it is possible to increase the problem of removing the dust adhering to the surface of the product, and the like, and the productivity is lowered as the additional work is performed.

Therefore, the method of printing the surface of one of the products into a metallic color is to insert and insert a synthetic resin transfer film which provides a fine line pattern printing layer, so that the printing layer is transferred to the surface of the molded product. This makes it possible to reproduce the metallic texture on the surface of the molded product while also reproducing the fine line pattern.

According to the prior art, in order to form a printed layer of a fine line pattern on the transfer film, the operator forms a thin line pattern with the computer image processing software, and then prints it to the translucent mask film, and then uniformly applies the photosensitive liquid on the silk screen surface. The mask film of the printed fine line pattern is placed on the silk screen surface, and only the thin line pattern portion is fixed to the photosensitive liquid for development, and then the fine line pattern is first formed on the transfer film through the silk screen surface and printed. The metallic color is then covered on the transfer film for a second time to cover the thin line pattern portion and silk-printed into a metallic color of different colors. Finally, the transfer film forming the printing layer is inserted and injection molded, and the metal texture is reflected on the surface of the molded product. And a thin line pattern.

However, according to the above method, the operator manually creates a thin line pattern by using the computer software, and prints it onto the transfer film after printing it to a film film or the like, that is, since the thin line pattern is formed by the computer software, the surface of the product is formed. The thin line pattern shown appears to be both simple and regular, with an unnatural pattern.

Further, the transfer film produced by the above method has a reduced processing elongation, and at the same time, in addition to the fine line pattern, there are limitations in realizing other luxury metal textures such as logos and patterns.

Therefore, in view of the above problems, an object of the present invention is to form a fine line pattern or a three-dimensional pattern of various patterns on a printed layer by using a transparent ink on the basis of forming a transfer film from the lower base film, and using a deposited metal thereon. The layer method can reflect the luxurious metal texture, and can also provide excellent processing elongation, which is very easy to apply to various shapes of molded products; after inserting and transferring, there is no additional follow-up work, and it is not transferred onto the surface of the molded product. The transferred printed portion is cleanly separated from the molded product, thereby improving the productivity while preventing the occurrence of defective products; providing a metal-like interpenetrating mold transfer film composed of a new component and a manufacturing method thereof .

The semi-hard ultraviolet (UV) coating has a weight of 100 relative to the photohard solid, and 5 to 45 parts by weight of an organic solvent is used in combination.

In addition, in the manufacturing method of the interposing mold transfer film, the printing layer uses a metal layer as a background decoration layer; a semi-rigid ultraviolet (UV) coating layer and a printing layer further form a primer ( Primer) layer.

In addition, in the manufacturing method of the interposing mold transfer film, the thickness of the three-dimensional pattern layer is 0.2 to 20 micrometers (um); the thickness of the fine line (Hairline) pattern is 0.2 to 2 micrometers (um); The thickness is 2 to 20 microns (um).

Further, the interposer transfer film of the present invention is manufactured as described above, wherein the interposer transfer film comprises a metallic three-dimensional pattern.

As described above, the interposer transfer film of the present invention is manufactured by forming a three-dimensional pattern on the printed layer using transparent ink, and depositing a metal layer on the surface thereof so that various patterns, trademarks, and logos including the fine line pattern appear.

Hereinafter, the interposer transfer film and the manufacturing method of the present invention including the metallic texture three-dimensional pattern will be described in detail.

Hereinafter, preferred embodiments of the present invention will be described in detail in conjunction with the drawings. The same reference numbers are used throughout the drawings to refer to the same or equivalent parts.

"Fig. 1" is an exploded sectional view showing the process of joining the transfer film and the molded product of the present invention.

Please refer to "FIG. 1", which shows the structure of the interposer transfer film 180 according to the present invention, specifically, a base film 100, a release layer 110, and a semi-hard ultraviolet (UV) coating from top to bottom. The layer 120, an undercoat layer 130 for increasing the adhesion of the printing layer, a printing layer 140, a three-dimensional pattern layer 150 using a transparent ink, a metal layer 160, and an adhesive layer 170 are sequentially formed. The molded product 200 is positioned below the adhesive layer 170, and the transfer mold transfer film 180 is transferred onto the surface of the molded product 200.

As described above, the semi-rigid ultraviolet (UV) coating layer 120 is completely hardened after the printing layer is formed on the surface of the molded product 200, and then the base film 100 and the release layer 110 are removed, thereby completing the interpenetrating mold transfer operation.

Here, although the description has been made in the order from top to bottom in the "first drawing", in actuality, the order in which the transfer film is interposed is the base film 100, which is formed in layers at the top. The actual manufacturing method for the interpolating mold transfer film is explained below.

First, a step of forming a release layer 110 is performed to spray a release agent over the base film 100. The base film 100 is made of Poly Ethylene Terephthalate (PET) or Poly Ethylene Terephthalate Glycol (PETG) resin. Because polyethylene terephthalate (PET) or polyethylene terephthalate (PETG) has superior thermal elongation compared to conventional base film materials, interspersed mold transfer film is selected from poly The resin of Poly Ethylene Terephthalate (PET) or Poly Ethylene Terephthalate Glycol (PETG) can maximize moldability.

Also, the release layer 110 may use a melamine release agent or an organic release agent. Since the melamine release agent or the organic release agent can be thinned in a liquid state, in the subsequent operation, when the ultraviolet (UV) coating 120 is completely hardened, it has a property of making the two layers easily separated.

Then, a step of forming an ultraviolet (UV) coating layer 120 is performed over the release layer 110. At this time, the semi-hard ultraviolet (UV) coating layer 120 means an ultraviolet (UV) hard resin layer which is partially cured by the first ultraviolet (UV) irradiation.

Therefore, the semi-hard ultraviolet (UV) coating is based on 100% by weight of the photohard solid, and comprises 91 to 95% by weight of the soft acrylate oligomer and 5 to 9% by weight of the sensitizing initiator. substance. The soft propylene is selected from the group consisting of urethane acrylate, octa methacrylate urethane, epoxy acrylate, epoxy methacrylate, acrylate, methyl methacrylate, acrylic acrylate, polyester acrylate, and octaamine modified acrylic acid. At least one of them.

Further, the semi-hard ultraviolet (UV) coating layer 120 is used in an amount of 5 to 45 by weight based on 100 parts by weight of the organic solid solvent. If the organic solvent does not reach the weight of 5 to 45, the fluidity is excessively lowered, which increases the difficulty in forming a film protective layer. If the organic solvent exceeds 45 parts by weight, the fluidity is greatly increased, and normal film development cannot be guaranteed.

Next, a step of forming the printed layer 140 is performed over the semi-rigid ultraviolet (UV) coating 120. In order to improve the adhesion of the printing layer 140 and the absorption properties of the ink after printing, a primer layer is formed on the surface of the semi-hardened ultraviolet (UV) coating layer 120. The undercoat layer 130 uses an acrylic or polyurethane polyol copolymer selected from inks excellent in absorbability. It is preferred that the undercoat layer 130 maintain a certain refractive index with the semi-curable ultraviolet (UV) coating layer 120 in order to prevent a rainbow phenomenon. That is, when the semi-rigid ultraviolet (UV) coating layer 120 reflects the outer surface at an angle based on the external image which is considered to be flat, the image of the oil droplet on the outer surface, that is, the rainbow phenomenon, is seen. To counteract the rainbow phenomenon described above, an undercoat layer 130 is further formed between the semi-rigid ultraviolet (UV) coating layer and the printed layer. The undercoat layer is preferably coated with a multi-color Gravuer Printing Machine having a thickness of 1.0 to 1.5 μm (um), dried at 100 ° C for 10 seconds, and then dried. A fermentation process of 24 hours was passed at a temperature of 40 °C.

Further, a portion of the printed layer 140 is printed on the undercoat layer 130 to represent various designs, characters or trademarks in various colors. In particular, the printed layer 140 of the present invention preferably utilizes the metal layer 160 as a decorative layer for the background.

The printing layer 140 is preferably a material comprising a pigment of 25 parts by weight, a synthetic resin of 15 parts by weight, and a hardener of 5 parts by weight. In this case, the curing agent should be made of a synthetic resin containing about 40% of a polyurethane copolymer. should.

The printed layer 140 is formed by a multi-color Gravuer Printing Machine and operates in accordance with the printing frequency set by the multi-color gravure rotary printing press. At this time, the thickness of the printed layer 140 is 1.0 to 1.5 micrometers (um), dried at 100 ° C for 10 seconds, and then subjected to a fermentation process at a temperature of 40 ° C for 24 hours to form a crosslinked printing layer. 140.

Again, the step of implementing the three-dimensional pattern layer 150 using transparent ink over the printed layer 140. The transparent ink preferably contains a two-component reactive ink of a polyurethane resin system. Since the polyurethane resin has high adhesion to the panel fabric, the adhesion of the panel fabric to the printing layer 140 can be increased while the strength of the metal layer 160 can be increased.

The three-dimensional pattern layer 150 can freely form a thin line pattern and a pattern, a mark of a positive or negative image, a label, etc., and one of the gravure, silk screen, and inkjet printing methods can be selected, and the characteristics of the fine line pattern can be expressed, and the three-dimensional pattern layer can also be expressed. A good intaglio or positive pattern. At this time, the thickness of the three-dimensional pattern layer 150 is 0.2 to 20 micrometers (um), so that it is sufficient to fully exhibit the three-dimensional feeling and the adhesive property.

If the thickness of the three-dimensional pattern layer 150 is 0.2 to 2 micrometers (um), the performance of the three-dimensional pattern layer 150 can be as fine as a fine and super high-level pattern. When the three-dimensional pattern such as a logo is displayed, the thickness of the three-dimensional pattern layer 150 is 2~ 20 microns (um) is the best.

If the thickness of the three-dimensional pattern layer 150 is less than 0.2 micrometers (um), the stereoscopic effect cannot be sufficiently exhibited, and the adhesion to the printed layer 140 or the metal layer 160 cannot be ensured. If the thickness of the three-dimensional pattern layer 150 exceeds 20 micrometers (um), the overall thickness of the transfer mold transfer film is increased, so that the moldability is lowered and the normal insertion mold transfer operation may not be performed.

Again, the step of depositing a metal layer on the surface of the three-dimensional pattern layer 150. The metal layer is formed by using at least one selected from the group consisting of aluminum, copper, and titanium, and is preferably subjected to a cathode vacuum sputtering (Sputtering) welding process, and has a thickness of 50 to 150 angstroms ( ). If the thickness of the metal layer 160 does not reach 50 angstroms ( ), the metal texture cannot be fully displayed; if the thickness of the metal layer 160 exceeds 150 angstroms ( The characteristic texture exhibited by the three-dimensional pattern layer 150 fails, and the thickness of the transfer film of the interposing mold is increased, which may cause a problem of deterioration in moldability.

Further, the metal layer 160 of the present invention may include a printed layer having a background of other colors in addition to the color inherent to the metal. At this time, only a portion of the mark indicating the metallic texture is subjected to a sputtering vacuum deposition operation, and for the remaining portion, the background printed layer can be formed in accordance with the step of forming the printed layer.

Finally, in order to perform the step of forming the adhesive layer 170 on the metal layer 160, the interposer transfer film is seamlessly adhered to the molded product 200. At this time, the surface of the metal layer 160 exhibits an uneven surface state due to the three-dimensional pattern layer 150.

An adhesive undercoat layer 165 is further formed between the metal layer 160 and the adhesive layer 170. However, it is not necessary to carry out the step of adhering the undercoat layer 165, and only the effect of the undercoat layer can be additionally applied to the adhesive layer 170 of the present invention. Because of the formation of the adhesive layer 170, the flattening of the surface of the metal layer 160 can be made more natural, and the adhesive synthesis process of the molded product 200 can be smoothly performed.

In summary, the present invention can display an excellent metallic texture through the three-dimensional pattern layer 150, thereby multiplying the decorative effect. In particular, the use of a three-dimensional pattern layer 150 comprising a fine line pattern, for example, a deposited aluminum exhibits a metallic texture of a silver fine line pattern; for example, a deposited copper can exhibit a gold fine line pattern. Further, if the above-described fine line pattern is used in combination with the logo of the positive or negative pattern, a more excellent decorative pattern can be exhibited.

"Fig. 2" is a side view of a three-dimensional pattern layer of a transfer film transferred in accordance with the present invention.

"Fig. 2" shows an example in which a three-dimensional pattern layer 150 on which an intaglio mark is printed on a surface formed with a transparent ink, and a fine line pattern is formed on the surface of the intaglio mark to form a luxurious metal texture.

In practice, the three-dimensional pattern is formed to display the thin line pattern after the intaglio mark is printed in the reverse direction; the insert pattern transfer film containing the pattern is applied to the molded product to be marked with a positive mark.

As described above, according to the manufacturing method of the interposer transfer film of the present invention, a transparent pattern is used to form a three-dimensional pattern on the printed layer, and a metal layer is deposited on the surface thereof, and a luxury pattern and a logo including various patterns of a thin line pattern can be displayed. , identification, and easy to operate.

Further, as described above, the interposer transfer film of the present invention has a high elongation rate and excellent moldability because of the use of a semi-hardened ultraviolet (UV) coating. After the transfer operation of the inserting mold is performed, the transferred printing portion and the release film can be cleanly separated from the printed layer transferred from the molded product, so that the subsequent operations can be omitted, and the workability and productivity can be improved.

While the invention has been described above in terms of the preferred embodiments thereof, it is not intended to limit the invention. It will be appreciated by those skilled in the art that modifications and modifications may be made without departing from the spirit and scope of the invention as disclosed in the appended claims.
