Description

{Nail art structure having antiviral function and manufacturing method thereof}

The present invention relates to a structure for nail art, and more specifically, to a structure for nail art and a method for manufacturing the same, which can exhibit a permanent antiviral function by mixing an antiviral composition into a semi-cured UV top gel composition.

Nail art, a field in the beauty industry, has recently been developing rapidly as an element of body expression art regardless of age and gender.

Conventional nail art uses a method of applying liquid pigments, such as nail polish in various colors, to fingernails or toenails and letting them dry. This requires a technique for evenly applying the liquid pigments, and even if they are evenly applied, it takes a long time to dry them, and there is a problem that they easily peel off partially or completely after drying.

Accordingly, UV gel nails have been developed, which apply a liquid pigment containing a UV curable resin composition to fingernails or toenails and then cure it using a UV irradiation device. UV gel nails have the advantages of being flexible and soft, not easily broken, having excellent gloss, and being firmly attached to the nail.

However, the manufacturing process is cumbersome, as it requires applying liquid gel nails to the nails, hardening them, attaching various shapes of patterns in the form of stickers or drawing them directly, and then applying a top coat or other reinforcing agent on top of them. In addition, the process of immersing the fingers in a harmful solvent for a long time is necessary to remove the UV gel layer, which is very harmful to the skin and nails.

Accordingly, dry nail stickers were developed to overcome the problems of liquid products such as manicures or UV gel nails. However, most dry nail stickers have a fixed shape, so they have poor adhesiveness, and their durability after attachment is very weak, which causes problems in their longevity. On the other hand, there are artificial nails that have excellent durability, but since they are made of hard plastic, they lack flexibility and elasticity, which reduces the feeling of wear and adhesiveness, so they do not naturally settle on the nail and tend to lift, which not only reduces the aesthetics, but also causes the problem of foreign substances or harmful bacteria being introduced into the spaced space.

In particular, recently, due to the coronavirus pandemic, the demand for sanitary issues, non-toxicity to the human body, and antibacterial and antiviral effects is also increasing.

There have already been many attempts and technologies to provide antibacterial properties to nail art structures. However, the antibacterial and antiviral ingredients that have been commonly used in the past have problems such as not lasting long, there is a risk of resistance developing and creating super bacteria, and they are toxic to the human body.

Hereinafter, implementation examples and embodiments of the present invention will be described in detail with reference to the attached drawings. However, the present invention may not be limited to these implementation examples and embodiments and drawings.

FIG. 1 is a schematic diagram illustrating a nail art structure according to one embodiment of the present invention.

Referring to Fig. 1, first, a substrate layer (100) can be prepared. The substrate layer (100) can be a base layer for forming a nail art structure, specifically, a UV semi-cured gel nail sticker.

There is no particular limitation on the type of the above-mentioned substrate layer (100), and when attaching a gel nail sticker to an adherend, any material that is flexible and elastic so that the sticker can be easily bent along the curved surface of the adherend may be used.

For example, the substrate layer (100) may be made of a thermosetting material made of a synthetic material based on polyol and isocyanate, or may be made of an ultraviolet curable material including at least one of a urethane acrylate oligomer having a functional group number of less than 6 and a monomer acrylate having a functional group number of 2 or more.

Next, a printing layer (200) can be formed on the front surface of the substrate layer (100). The printing layer (200) can be formed to express the background color of the gel nail sticker to provide visual aesthetics.

The above printing layer (200) may be formed as a single layer or multiple layers of two or more layers. When multiple layers are laminated, the colors of the pigments can be laminated in multiple single layers to implement more vivid colors, and color combinations can be expressed in various ways, and new color combinations can be implemented by utilizing techniques such as gradation, color matching, and complementary colors.

For example, the printing layer (200) may be formed by a silk screen printing method, an offset printing method, or a direct digital (DDP) printing method. However, the manufacturing method is not limited thereto.

Next, a UV pattern layer (300) can be formed on the entire surface of the printing layer (200).

The above UV pattern layer (300) may be a layer for implementing various design elements such as color, pattern, design, and decoration in a gel nail sticker.

There is no significant limitation on the method of forming the above UV pattern layer (300), but it can be manufactured using, for example, a UV printing method.

For example, it is preferable that the UV pattern layer (300) be formed as a soft type UV pattern layer with a thickness of 6 ㎛ or less.

Next, a deposition layer (400) can be formed on the UV pattern layer (300). The deposition layer (400) can be formed by applying pigments that maintain various colors in order to express design elements such as the color of the gel nail sticker. However, it is not limited thereto, and components and manufacturing methods commonly used in the relevant field can be formed by designing and changing them in any way.

For example, it is preferable that the deposition thickness of the deposition layer (400) be formed to be 2,000 Å or less.

Next, a first semi-cured UV top gel layer (500) can be formed on the deposition layer (400). The first semi-cured UV top gel layer (500) can include a UV resin and be cured by ultraviolet rays.

The first semi-cured UV resin composition for forming the first semi-cured UV top gel layer (500) may be, for example, a mixture of 10 to 40% of a UV-curable resin and 60 to 90% of a thermosetting resin. If the mixing ratio of the thermosetting resin is less than 60%, the curability is reduced, and if it exceeds 90%, there is a disadvantage in that flexibility is reduced due to high curability.

In one embodiment, the UV curable resin may further include 1 to 3 parts by weight of a photoinitiator having a light wavelength range of 200 nm to 600 nm per 100 parts by weight of a UV resin mixed with at least one of urethane acrylate, epoxy acrylate, and polyester acrylate.

The above photoinitiator can be used alone or in combination with an a-hydroxy ketone type and a phenylglyoxylate type initiator in equal amounts. The a-hydroxy ketone type photoinitiator as described above has excellent transparency after curing, and the phenylglyoxylate type photoinitiator has excellent effects of surface curing and improving the physical properties of a transparent coating, so they are used alone or in combination.

In addition, the UV resin is a mixture of at least one of urethane acrylate, epoxy acrylate, and polyester acrylate, and ideally, 10 to 30 parts by weight of epoxy acrylate and 10 to 20 parts by weight of polyester acrylate are mixed with 100 parts by weight of urethane acrylate.

The reason for applying a mixture of multiple UV resins as described above is that urethane acrylate has good reactivity, is easy to cure, maintains flexibility after curing, and has little yellowing.

In addition, epoxy acrylate has high reactivity, so it has good hardness and polishing properties, is easy to harden, has excellent flexibility, and can be hardened stably even when in contact with oxygen.

In addition, polyester acrylate has the advantage of excellent reactivity and lower viscosity than urethane acrylate and epoxy acrylate, resulting in excellent pigment dispersibility.

By mixing the UV resin to take advantage of its characteristics, it maintains a semi-cured state, does not rapidly harden when exposed to air, and has poor durability after attachment, improving the inconvenience of easily falling off.

The above thermosetting resin may be a mixture of 100 parts by weight of a composition mixing at least one of non-toxic substances such as epoxy resin, acrylic resin, and polyester resin, and 100 to 200 parts by weight of a composition mixing at least one of butyl acetate, ethyl acetate, acetone, and isopropyl alcohol for dissolving the solid resin or adjusting the viscosity.

The above thermosetting resin may be applied as a one-component or two-component type depending on whether it is in a solid or liquid state and whether a curing agent and a solvent are included, but is not limited thereto.

The specific process for forming the first semi-cured UV resin composition and the first semi-cured UV top gel layer (500) can follow a known technology.

Next, a second semi-cured UV top gel layer (600) can be formed on the first semi-cured UV top gel layer (500). The second semi-cured UV top gel layer (600) contains an antiviral composition and exhibits excellent antiviral and antibacterial effects.

Specifically, the second semi-cured UV top gel layer (600) may be formed by mixing the first semi-cured UV resin composition and the antiviral composition. It may be the same as the first semi-cured UV resin composition used in the second semi-cured UV top gel layer (600), or, in some cases, there may be differences in some components and mixing.

The above antiviral composition is a liquid composition based on an acid component, and is mixed with the first semi-cured UV top gel composition to enable the second semi-cured UV top gel layer (600) to exhibit a permanent antiviral effect.

The above antiviral composition may specifically include one or more components selected from carboxylic acid, organotitanium compound, and combinations thereof, and a solvent.

The above carboxylic acid may be at least one selected from acetic acid, i.e., acetic acid, trifluoroacetic acid, and combinations thereof. For example, the above carboxylic acid may include acetic acid and trifluoroacetic acid.

The above organotitanium compound may be tetraisoprpoxy titanium (synonym: Titanium(Ⅳ)isopropoxide).

The solvent may be an aqueous solvent, specifically, water.

For example, the antiviral composition may include acetic acid, trifluoroacetic acid, tetraisoprpoxy titanium, and water.

In this case, the acetic acid may be included in an amount of 15 to 20 wt%, specifically, 16 to 19 wt%, more specifically, 16.5 to 18.5 wt%, based on the total weight of the composition. The trifluoroacetic acid may be included in an amount of 5 to 10 wt%, specifically, 6 to 9 wt%, more specifically, 6.5 to 8.5 wt%, based on the total weight of the composition. The tetraisopropoxytitanium may be included in an amount of 7 to 13 wt%, specifically, 8 to 12 wt%, more specifically, 8.5 to 11.5 wt%, for example, 10 wt%, based on the total weight of the composition. The water may be included as a remainder based on the total weight of the composition.

In the case of existing antibacterial and antiviral compositions, most of them use the toxicity of metals such as silver nano, copper, and zinc to kill bacteria. However, these methods have the problem that the antibacterial effect gradually decreases as the frequency of exposure increases, resulting in significantly lower performance and durability. In addition, there is a concern that resistance may develop and create super bacteria. In addition, there is the problem that the toxicity of the metals can have a harmful effect on the human body.

In contrast, an antiviral composition according to one embodiment of the present invention provides a composition of ingredients that are not harmful to the human body based on an acid component and a water-soluble solvent, has an antibacterial performance of 99% or more, physically destroys viruses so that resistance does not develop, and can exhibit an effect in which high antibacterial performance is maintained even when the frequency of use increases and can be used permanently.

It is preferable that the above antiviral composition be blended in an amount of 15 to 20 wt% based on the total weight of the first semi-cured UV resin composition.

The above-described mixing ratio enables the second semi-cured UV top gel layer (600) to maintain its shape, properties, etc., while at the same time exhibiting permanent antibacterial and antiviral effects.

The specific process for forming the second semi-cured UV top gel layer (600) can follow a known technology.

Meanwhile, an adhesive layer (not shown) for direct attachment to a nail may be further provided on the lower portion of the substrate layer (100), and a release film (not shown) may be further provided on the lower portion of the adhesive layer.

The above adhesive layer may include, but is not limited to, at least one of acrylic, urethane and silicone.

The above release film is a detachable transparent or semitransparent film that can be separated from the substrate layer (100) without damage. The above release film maintains the function of an adhesive during storage, thereby preventing the problem of adhesion to the packaging material. The above release film can use, for example, a release paper that has been surface-treated with fluorine and coated with a silicone series.

According to one embodiment of the present invention, a nail art structure can be provided that can exhibit a permanent antiviral function by mixing an antiviral composition into a semi-cured UV paint.

The above description of the present invention is for illustrative purposes, and those skilled in the art will understand that the present invention can be easily modified into other specific forms without changing the technical idea or essential characteristics of the present invention. Therefore, it should be understood that the embodiments described above are exemplary in all respects and not restrictive. For example, each component described as a single component may be implemented in a distributed manner, and likewise, components described as distributed may be implemented in a combined manner.

The scope of the present invention is indicated by the claims set forth below, and all changes or modifications derived from the meaning and scope of the claims and their equivalent concepts should be interpreted as being included in the scope of the present invention.
