BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a polishing tool for exfoliating a body or polishing a nail, and more particularly, to an exfoliation having a polishing surface formed by coating an abrasive on at least one surface of a polishing tool body made of metal or plastic. Or it relates to a polishing tool for nail polishing and a method of manufacturing the same.

In areas of the body where the hands, feet, and knees are subjected to frequent compression or repeated friction, the skin's epidermis easily ages, resulting in a thick stratum corneum. If the stratum corneum is not removed, the part becomes rough while it is dry, the skin hardens and cracks, causing pain and unsatisfactory results. Therefore, the keratinized part has a rough polishing surface during the bath. Rubbing off with a sphere.

As one of such polishing tools, a polishing tool having a polishing surface coated with an abrasive is used. Conventionally, a polishing tool of this type has been produced by applying an adhesive to the surface of a main body to form a polishing surface, applying an abrasive on the thus applied adhesive, and then applying the adhesive again on the abrasive.

However, in the polishing tool manufactured by this method, since the abrasive is bonded to the main body by the adhesive, the bonding strength is low, so that the abrasive is easily detached during use, and thus, the polishing tool is short and not practical, and efficient polishing surface formation is achieved. There are problems such as difficulty.

Therefore, the present invention has been researched and developed in view of the problems of the prior art as described above, the object is to remove the exfoliation that can easily form the polished surface in a desired form without damage to the polished surface even after long-term use It is to provide a nail polishing polishing tool and a method of manufacturing the same.

According to the present invention to achieve the above object, in a polishing tool for exfoliation or nail polishing having a polishing surface coated with an abrasive on at least one surface of the main body, the surface of the main body to form the polishing surface in a silk screen device Conductive ink layer formed by printing in a predetermined pattern, an abrasive layer laminated on the conductive ink layer, and a metal plating layer covering the conductive ink layer and the abrasive layer is formed for exfoliation or toenail polishing Polishing tools are provided.

In addition, according to the present invention, as one of the preferred methods for manufacturing the above-described abrasives, the method comprising: forming a conductive ink layer by silkscreen printing in a predetermined pattern using conductive ink on at least one surface of the main body of the abrasive; Attaching an abrasive to the conductive ink layer formed by silkscreen printing to form an abrasive layer; And electroplating at least a portion where the conductive ink layer and the abrasive layer are formed to form a metal plating layer covering the two layers. A method of manufacturing a polishing tool for exfoliation or nail polishing is provided.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings illustrating an example of a polishing tool according to the present invention.

1 is a perspective view of an exfoliation polishing tool according to the present invention, Figure 2 is a detailed cross-sectional view showing a laminated structure of the polishing surface with respect to the A-A line in the polishing tool of FIG.

The exfoliation polishing tool shown in FIG. 1 includes a main body 10, a handle portion 11 integrally formed on one side of the main body 10, and an abrasive surface 20 formed on at least one surface of the main body 10. ).

As shown in detail in FIG. 2, the polishing surface 20 includes a conductive ink layer 21 on at least one surface of the main body 10, an abrasive layer 22 stacked on the conductive ink layer 21, and A metal plating layer 23 covering the conductive ink layer 21 and the abrasive layer 22 is provided.

As the material of the main body 10, a metal such as nickel, chromium or the like plated on a metal such as aluminum, or a plastic such as ABS or the like may be used.

The conductive ink layer 21 may be formed using a conductive ink in a silk screen device for printing a predetermined pattern (for example, a stripe pattern as shown in FIG. 1) on at least one surface of the main body 10. In this case, as the conductive ink, any kind of conductive ink capable of silk screen printing may be used, and specific examples thereof include conductive ink including copper, silver, carbon, and the like as a metal component.

The conductive ink layer of the present invention not only provides the effect that the abrasive layer laminated thereon is firmly adhered in the subsequent plating process, but in order to perform metal plating when the main body is plastic, an expensive non-electrolyte plating solution should be used. By using the conductive ink layer according to the present invention, an effect of using an inexpensive electrolyte plating solution can also be obtained.

The abrasive layer 22 is laminated on the conductive ink layer 21. In order to facilitate lamination of the abrasive layer 22, it is preferable to attach the abrasive before the conductive ink layer 21 is dried. The conductive ink may contain an additive for increasing the binding property to the abrasive. In this case, as the abrasive, generally used abrasive particles may be used. In particular, the use of an abrasive such as white alumina facilitates subsequent electroplating and is effective because of excellent adhesion.

The abrasive is used by adopting a suitable one for use, for example, in the case of exfoliation, rough use 60 ~ 120 mesh and fine use 150 ~ 220 mesh, for nail polishing, rough rough 150 Use 180 ~ 180 mesh, fine 220 ~ 600 mesh depending on the purpose.

The metal plating layer 23 covers the conductive ink layer 21 and the abrasive layer 22. When the material of the body 10 is conductive, the metal plating layer 23 also covers the surface of the body contacting the plating liquid. Examples of preferred metals for use in electroplating for forming the metal plating layer 23 include nickel, chromium, etc. Of these, nickel is advantageous in terms of cost reduction of the product.

Hereinafter, a method of manufacturing the polishing tool according to the present invention will be described by the method of the embodiment.

Example 1

After the surface of the aluminum substrate is subjected to pretreatment including alkali degreasing, pickling, washing with water and Bondal Dip treatment, nickel sulfamate 300-600 g / L, nickel chloride 5-50 g / L, boric acid in the electroplating apparatus. It was immersed in the plating liquid containing 30-60 g / L and a brightening agent. Next, using a DC rectifier, metal nickel is added to the + pole in the titanium net, and the pre-treated abrasive body is hung on the pole. Then, about 10-30 at DC voltage of 1-4V and current 1-2A. After energizing for about 1 minute nickel plated, washed and dried.

Next, the conductive ink is printed on the surface of the primary nickel plated substrate on which the polishing surface is to be formed in a predetermined pattern by using a silk screen device to form a conductive ink layer, and white alumina is used as an abrasive before the conductive ink layer is dried. Apply on the conductive ink layer and dry. Thereafter, secondary nickel plating was conducted by energizing for about 1 hour under the same conditions as the primary nickel plating to form a nickel plating layer covering the conductive ink layer and the abrasive layer, and dried after washing with water.

As a result of polishing experiments on a plastic abrasive product having conditions similar to keratin with the polishing tool having the polishing surface formed as above and the polishing tool having the polishing surface formed by the conventional adhesive method, In the polishing operation of 100-200 times, the removal of the abrasive occurred, but in the case of the polishing tool of this embodiment, the removal of the abrasive did not occur even in the number of times of polishing.

Example 2

To form the polishing surface of the plastic sheet, a conductive ink layer is printed on the surface by using a silk screen device to form a conductive ink layer. Before the conductive ink layer is dried, white alumina is applied to the conductive ink layer and dried. Next, it was immersed in a plating solution containing nickel sulfamate 300-600 g / L, nickel chloride 5-50 g / L, boric acid 30-60 g / L and a brightening agent in the electroplating apparatus. Next, using a DC rectifier, put a metal nickel on the + pole in a titanium mesh,-hang the body of the polishing tool with the abrasive on the pole, and then, for about 10-30 minutes under the conditions of DC voltage 1V and current 1A After conducting primary nickel plating by energization, secondary nickel plating was conducted by energizing for 40 minutes under a condition of voltage 1.5V and current 5A to form a nickel plating layer covering the conductive ink layer and the abrasive layer, followed by rolling.

If the plastic plate is ABS resin, the conductive ink is printed on the surface by using a silk screen device to form a conductive ink layer on the surface to form the conductive ink layer, and the conductive ink layer is used as an abrasive before the conductive ink layer is dried. The white alumina was attached onto the conductive ink layer and dried, and then the conventionally known non-electrolytic plating method was adopted to prepare the polishing tool of the present invention.

As a result of the polishing experiment with the polishing tool having the polishing surface formed according to the present invention and the polishing tool having the polishing surface formed by the conventional adhesive method, and subjected to the polishing of plastic polished materials with similar conditions to keratin, Even in the case of the polishing tool, the removal of the polishing agent did not occur even in the number of polishing times 10 times or more than the polishing number in which the abrasive removal of the conventional polishing tool occurred.

As described above, the polishing tool according to the present invention has a polishing surface in which the abrasive is firmly fixed by metal plating, so that desorption of the abrasive from the polishing surface does not occur even after long-term use, and the desired pattern is used because the silkscreen printing technique is used. It can be easily given, and also has advantages such as easy manufacturing and low manufacturing cost.
