Surface treatment method of metal beauty tool {A SURFACE TREATMENT METHOD OF METALLIC CARE TOOL}

The present invention relates to a method for treating a surface of a metal cosmetic tool for printing a desired decorative pattern and coating silver nanoparticles, and more particularly, comprising printing, washing, silver nano coating, stabilization and hot air drying of the plated metal. A surface treatment method of a metal beauty tool.

Metals are very excellent in durability and rigidity, and are widely used in various kinds of household articles requiring such physical properties.

However, these household goods, especially products such as metal nail clippers have a disadvantage in that they are simple in appearance due to the nature of the material, so that a monochromatic paint layer is formed on the upper surface of the push lever of the nail clipper through spray painting or electrodeposition plating, or a separate decoration is provided. A side may be attached to show aesthetics.

The conventional decorative piece is formed of a transparent acrylic plate, and after forming a desired pattern through several times silk printing on the bottom surface of the decorative piece made of a transparent acrylic material, it can be produced by painting the background color. In this case, the silk printing is performed as many as the number of colors included in the pattern, and is mostly done by hand. Therefore, the labor cost increases as the number of colors increases, and it is difficult to accurately match a pattern when performing silk printing, so that the print quality decreases as the number of colors increases.

In addition, since the color that can be used for silk printing is limited, it is difficult to provide not only a variety of colors but also a gradation effect that gradually changes the color. In addition, the conventional nail clipper decoration piece produced in the above manner has a disadvantage that the adhesion between the printed bottom surface and the metal surface is not easy to fall off the metal surface, the work price is lowered in the production of a small amount of production cost increases.

In addition, the method of forming a desired pattern through several times of silk printing uses a large number of different colors of ink, which causes a lot of problems in preparation for preparation and after finishing work, and discards the remaining ink after the silk printing is finished. Even when the problem occurs, such as environmental pollution.

In addition to such appearance problems, nail clippers are widely used in general homes, lodgings, baths, beauty salons, and the like, and are used by unspecified majority of people, and thus risks exist in hygiene.

Nail clippers can be easily contaminated by bacteria or viruses because they are used by many people due to their characteristics. Especially, when bleeding occurs while cutting nails, they are frequently infected with bacteria or viruses present in nail clippers, causing serious inflammation. .

In order to solve this problem, various studies have been conducted to prevent bacteria or viruses from living by treating antimicrobial substances on the surface of nail clippers.

Silver (silver) has been used for the body to check the imbalance of the body that they do not feel because the gloss or color changes depending on the physical condition when worn on the body from ancient times, and has been recently used as various antibacterial materials.

However, when the surface is coated with silver, there is a disadvantage that the coating layer is relatively weak and the coating layer is peeled off over time. In particular, in the case of the nail clipper, the silver coating of the blade part was easily peeled off.

The present invention has been made in order to solve the above problems, the problem to be solved by the present invention, the desired pattern can be printed on the desired portion without restriction of material or color, silver nano coating layer giving antimicrobial power is easily peeled off It is an object of the present invention to provide a method for surface treatment of metallic cosmetic tools.

In order to solve the above problems, the surface treatment method of the metal cosmetic tool of the present invention is characterized by comprising the following steps:

(1) painting a base color on the surface to be decorated of the plated metallic beauty tool through spray painting or electrodeposition, and printing a desired pattern on the base color using a flatbed printer;

(2) ultrasonically cleaning the printed metallic cosmetic tool;

(3) silver nano coating the surface of the cleaned metallic cosmetic tool;

(4) soaking the coated metallic cosmetics tools in water to stabilize them; And

(5) hot-air drying the stabilized metallic beauty tool.

In addition, the surface treatment method of the metal cosmetic tool of the present invention is characterized by comprising the following steps:

(1 ') adhering a decorative piece made of an acrylic material printed with a desired pattern to a surface to be decorated by a plated metallic beauty tool using a flatbed printer;

(2) ultrasonically washing the metallic beauty tool to which the sequin is adhered;

(3) silver nano coating the surface of the cleaned metallic cosmetic tool;

(4) soaking the coated metallic cosmetics tools in water to stabilize them; And

(5) hot-air drying the stabilized metallic beauty tool.

Examples of the metal beauty tool of the present invention are nail clippers, nail cleaning tools, tweezers, earpicks, files, and the like.

In the step (1), the method of printing on the surface of the plated metal hairdressing tool of the present invention, after painting the base color through the spray painting or electrodeposition process on the upper surface of the metal to be decorated in the metal hairdressing tool, the flatbed printer It is a method of directly printing a desired pattern on the background color.

In addition, in the step (1 '), the printing method using the decorative piece is a method of improving the aesthetics by attaching the decorative piece to the metal upper surface of the portion to be decorated in the plated metal beauty tools, the decoration formed of acrylic material It is a method of directly printing a desired pattern on a piece using a flatbed printer, and attaching the decorative piece to a metal upper surface of a part to be decorated by the metal beauty tool. At this time, the pattern printed on the decorative piece is preferably formed on the inclined surface connecting the upper surface and the bottom surface, as well as formed on the upper surface of the decorative piece. As such, if the pattern is not printed on the bottom surface of the decorative piece, the adhesion is improved when the decorative piece is attached to the upper metal surface. That is, in the related art, as the base color is applied to the nail clipper in a state where the base color is applied to the bottom surface of the decorative piece, there is a problem that the adhesive force is lowered due to the ink of the base color portion, but this problem does not occur in the present invention. In addition, the decoration piece used in this method does not necessarily need to be formed of an acrylic material of a transparent material unlike the conventional art. Conventionally, in order to project the pattern printed on the bottom surface of the decorative piece to the upper side of the decorative piece, the decorative piece is formed of acrylic material of transparent material, but in this method, the decorative material is printed directly on the surface of the decorative piece so that the decorative material is decorated with an opaque acrylic material. Forming a piece does not cause any problem.

In the above steps (1) and (1 '), a desired pattern is printed on the surface or decorative piece of the metal beauty instrument using a jig using a flatbed printer. At this time, the flatbed printer used is a printer that allows printing on the surface of the to-be-printed material having various thicknesses by adjusting the distance between the printing means for ejecting ink and the surface of the to-be-printed object. A flatbed printer capable of printing while transferring is disclosed in Korean Patent No. 10-877899. Therefore, after designing a desired pattern, picture, text, etc. using a computer, it can be immediately output through a flatbed printer, and it is possible to immediately manufacture a product including a decoration designed to meet the needs of the customer. As described above, in the present invention, since the pattern is completed through one printing using the flatbed printer, the print quality is excellent and the quality is constant, thereby reducing the risk of defects. In addition, the present invention can work regardless of the demand amount, such as small quantity production or mass production, and is particularly excellent in the production of small quantities of many kinds.

The cleaning of the step (2) is to remove foreign matters remaining on the surface of the plated metal such as chromium plating and the gap generated during the printing and / or bonding process of the step (1) or (1 '), It may be carried out according to a conventional ultrasonic cleaning method. Preferably it is carried out for 30 to 90 seconds at a temperature of 50 ~ 60 ℃. If out of the temperature and time range there is a problem that a sufficient washing effect is not obtained.

Step (3) is a process of coating the metal surface with a coating agent containing silver nanoparticles in order to impart antimicrobial activity to the plated metal surface. The silver nanoparticles are preferably about 1 nm in diameter, and may vary depending on the concentration of the coating agent used. Generally, the silver nanoparticles are preferably used at a concentration of about 500 ppm based on the coating agent concentration of 40 ml / l. The coating agent may be any kind as long as it is generally used, but is preferably a ceramic coating agent. Preferred coating conditions are carried out for 30 to 90 seconds at 35 ~ 45 ℃, if less than the above range does not produce a sufficient coating layer, if it exceeds the above range the coating layer is too thick can not produce the desired product Occurs.

Step (4) is a stabilization process for preventing the silver nano coating layer completed from step (3) from being easily peeled off, and it is preferable to deposit the silver nano coated metal in water of 40 to 60 ° C. for 10 to 20 seconds. . If it is out of the above range occurs a problem that can not stabilize the coating layer to the desired degree.

The step (5) is a process of drying the stabilized coated metal product in water, it may adopt a natural drying or hot air drying method according to a conventional method, it is to dry hot air at a temperature of 70 ~ 90 ℃ desirable. If it is less than the temperature range has a disadvantage that the drying time is too long, if it exceeds the temperature range there is a problem that the coating layer becomes unstable.

The method of directly printing on the metal beauty tool of the present invention, because it prints a multi-colored pattern through a single printing operation, it is possible to express a variety of colors, the print quality is constant, there is an effect that can save labor costs The printing method of the metal beauty tool using the sequins removes the limitation of the acrylic material used as the sequins, and since the bottom surface of the sequins does not have ink, the adhesive strength between the sequins and the metal surface is improved and the sequins are improved. There is an effect that does not easily fall, the silver nano coating layer according to the present invention has an excellent antibacterial properties, there is an effect that the peeling of the coating layer does not easily occur.

Hereinafter, the present invention will be described in more detail with reference to Examples.

A paint layer was formed on the surface of the push lever of the nail clipper plated with chrome through spray painting, and a pattern was printed using a flatbed printer. Next, ultrasonic cleaning was performed at 60 ° C. for 1 minute. After the ultrasonic cleaning was completed, 500 ppm of silver nanoparticles having a particle size of 1 nm in diameter was coated for 1 minute at 40 ° C. using a ceramic coating agent (40 ml / l). After the coating was completed, the coating layer was stabilized by immersion in water at 50 ° C. for 10 seconds. After the stabilization step, hot air was dried at 80 ° C.

Example 2

In the process of Example 1, after forming a paint layer on the surface of the pressing lever of the nail clipper, instead of printing the plate directly, the plate printing on the upper surface and the inclined surface of the acrylic plate, and then bonding it to the pressing lever surface of the nail clipper The same process as in Example 1 was carried out except that was adopted.

Comparative Example 1

A nail clipper was manufactured in the same manner as in Example 1 except that the stabilization step was not performed.

Comparative Example 2

Instead of the printing method of Example 2, it was carried out in the same manner as in Example 2, except that a method of printing a pattern by a conventional silk printing method on a transparent acrylic plate.

2. Antimicrobial Activity

Escherichia coli was shaken in liquid medium, and the cultured strains were diluted and used for the test. After filling a 500 ml flask with 175 ml of a neutralizing solution, the nail clippers prepared in Example 1 and Comparative Example 1 were each added. After inoculation of the test strain, shaking culture for 24 hours at 120 rpm, 37 ℃. The culture solution was diluted 10-fold, 100 μl of the diluted culture solution was plated on a plate medium, and then cultured at 37 ° C. for 24 hours. The number of bacteria was measured and shown in Table 1 below.

division Initial concentration (CFU / ml) After 24 hours (CFU / ml) Control group (not nail clipper) 2.7 × 10 ³ 5.4 × 10 ⁵ Example 1 2.7 × 10 ³ 3.0 × 10 ⁵ Comparative Example 1 2.7 × 10 ³ 2.3 × 10 ⁴

As can be seen in Table 1, the silver nano-coated nail clippers subjected to the stabilization process of the present invention, it can be seen that the growth rate of Escherichia coli is very small compared to the nail clippers not subjected to the stabilization process.

3. Adhesion of the decorative piece adhered to the push lever

In order to find out the adhesive force of the sequins bonded to the push levers of the nail clippers manufactured by the steps of Example 2 and Comparative Example 2, the sequins were separated from the push levers by applying a constant force to the sequins, and the force at that time was measured. It was. As a result, it was confirmed that the decorative piece of Example 2 is completely separated from the push lever when a force of about 2 times or more is applied to the decorative piece of Comparative Example 2.
