Conductive composition for nail coating {CONDUCTIBLE COMPOSITION FOR NAIL COATING}

The present invention relates to a conductive composition for nail coating, and more particularly, to a conductive coating for nails to provide a conductivity to the user's fingernails when using a capacitive touch screen, so that the touch screen can be manipulated even at the nail site. It relates to a composition.

The present invention relates to a conductive composition for nail coating, and more particularly, to a composition for providing a conductivity to a user's fingernails when the capacitive touch screen is used so that the touch screen can be manipulated even at the nail site. .

With the recent rapid increase in smartphones and tablet PCs, the usage of touch screens, which are the major components of smartphones and tablet PCs, is also increasing.

Touch screens have a variety of operating principles, but are typical of pressure-sensitive, capacitive, and infrared type. In the case of immersion type, a string of sensors responding to the pressure applied to the surface of the screen is closely installed. Although it has been used a lot in the past, the frequency of use has recently been reduced due to some disadvantages in precision.

In the case of the capacitive type, the method developed to increase the precision on the screen, which is a disadvantage of the above-described attenuation type, is charged to the surface of the screen (current flow), and the degree of loss of the charge on contact after installing sensors around the screen. Detecting where the contact was made by detecting the, there is a disadvantage that the unit price is relatively higher than the sensitized expression.

In addition, there is an infrared method that uses a higher density sensor to detect the location of the contact by detecting infrared blockage by installing infrared rays around the screen, which is not directly applied to the screen and contaminates the screen surface. It is mainly used in an easy environment, but there are disadvantages in that it is restricted only in the field of use.

Recently, among the three methods described above, capacitive is most commonly used, and most of the smartphones and tablet PCs currently on the market employ capacitive touch screens.

However, the above-mentioned electrostatic type is a method of inputting a signal to the touch screen through the flow of electric current generated from a human hand, because the female user has a relatively long nail length, because the nail cuts off the current. There was a difficulty in operating the touch screen.

An object of the present invention is to provide a conductive coating composition for nail coating by mixing a conductive material in the coating liquid to be coated on the nail, the operation of the capacitive touch screen through the distal end of the nail.

The object of the present invention is achieved by providing a conductive composition for nail coating, characterized in that it consists of a nail coating liquid and a conductive mixture.

According to a preferred feature of the invention, the conductive coating composition for nails is to be composed of 75 to 99.9 parts by weight of the nail coating liquid and 0.1 to 25 parts by weight of the conductive material.

According to a more preferred feature of the invention, the nail coating solution is to be made of one selected from the group consisting of nail polish, nail nutrient and nail enhancer.

According to a more preferred feature of the invention, the conductive material is made of at least one selected from the group consisting of aluminum oxide, silicon oxide, magnesium oxide, zinc oxide, titanium oxide, zirconium oxide, iron oxide, nickel and copper.

According to an even more preferable feature of the present invention, the conductive material is to be made of a mixture of an acrylic mixture in a ratio of 1: 1 compared to the conductive material.

According to a further preferred feature of the invention, the acrylic mixture is to be made of one or more selected from the group consisting of butyl acrylate, methyl methacrylate, 2-hydroxypropyl methacrylate and 2-ethylhexyl acrylate.

In the conductive composition for nail coating according to the present invention, the conductive material is mixed with the nail coating liquid, and when the conductive composition for nail coating is applied to the nail, the capacitive touch screen can be operated at the distal end of the nail, thereby allowing the user to control the touch screen. It shows the outstanding effect for the convenience.

In the following, preferred embodiments of the present invention and the physical properties of each component will be described in detail, which is intended to explain in detail enough to be able to easily carry out the invention by one of ordinary skill in the art, This does not mean that the technical spirit and scope of the present invention is limited.

The conductive composition for nail coating according to the present invention is made of a nail coating liquid and a conductive material, more preferably 75 to 99.9 parts by weight of the nail coating liquid and 0.1 to 25 parts by weight of the conductive material.

The above-mentioned nail coating liquid contains 75 to 99.9 parts by weight, and consists of one selected from the group consisting of nail polish, nail nutrient and nail enhancer, which aesthetically improves the surface of the nail, nourishs damaged nails and physically impacts the nail. It protects against

If the content of the nail coating liquid is less than 75 parts by weight, the conductive coating composition for nail coating is easily peeled off after being coated on the surface of the nail, if the content of more than 99.9 parts by weight there is a problem that the conductivity of the conductive coating composition for nails is reduced.

At this time, any one of the above-described nail polish can be used as long as it is generally used, but a nail polish made of nitrocellulose or vinyl-based synthetic resin, a solvent, a plasticizer and a pigment is preferable. In this case, acetone or alcohol is preferable. As the plasticizer mentioned above, the component which consists of camphor and ethyl benzoate is preferable.

The aforementioned nail nutrients can be used as long as they are harmless to the human body and can moisturize or nourish the skin, such as components of mask packs that are commonly used, and calcium components are contained in keratin like cosmetic coatings. It is preferable to add a protein component purified from fruit, and these nail nutrients are prepared in liquid form, such as a viscous gel type or cosmetic material, and applied to the nail.

The nail enhancer described above may be any component that can improve the strength of the nail by providing nutrition and moisturizing effect to the surface of the nail, and it is preferable that the nail enhancer is made of glycerin, an exfoliating agent and the like having excellent moisturizing effect.

The above-mentioned conductive material is added in an amount of 0.1 to 25 parts by weight and comprises at least one selected from the group consisting of aluminum oxide, silicon oxide, magnesium oxide, zinc oxide, titanium oxide, zirconium oxide, iron oxide, nickel and copper. Conductive material consisting of serves to make the conductive composition for nail coating to have a conductivity.

If the aforementioned conductive mixture is added in less than 0.1 parts by weight, the conductivity of the conductive composition for nail coating is lowered, and if it exceeds 25 parts by weight, the manufacturing cost is increased without improving conductivity.
