Description

Manufacturing method of coating accessories

The present invention relates to a method for manufacturing a coating accessory, and more particularly, to a method for manufacturing a coating accessory that can easily form a pattern on the coating accessory.

In general, various types of accessories are used for clothes, bags, etc. (hereinafter collectively referred to as 'clothing'). Such cladding accessories include buttons, trademarks or other marks which are mainly used as fastening means for joining and separating, and badges or pendants for decorative effects.

In recent years, buttons are becoming more important to display a brand or image for one fashion accessory or high-end that completes the overall fashion of the cloth, rather than this traditional use.

In practice, the buttons are attached to the coating so that the top surface is exposed to the outside, so that symbols, characters, figures, and the like (hereinafter, referred to as 'patterns') are mainly represented on the top surface of these buttons.

On the other hand, the decoration of pendants for displaying the trademark or other marks of the coating or for decorative effect is also important day by day its function and role.

In the case of forming a pattern (hereinafter, referred to as a 'metal pattern') of a metal material on the coating accessory, the appearance may be elegant as well as an elegant image due to the unique luster of the metal material. In addition, the effect of improving the durability can be expected.

As an example of a manufacturing method of such a coating accessory, a technique of manufacturing a metal pattern through a separate mold work as shown in FIG. It is. However, such a conventional manufacturing method is difficult to form a sophisticated and complicated pattern due to the mold work. In addition, the design of the pattern is difficult to give a variety of changes, there was a problem such as a sense of unity between the pattern and the accessories after completion.

In addition, the manufacturing method of the conventional coating accessories has a problem that it is difficult to add a variety of colors during the lettering work (trademark, letters, etc.). That is, since the metal layer deposition is difficult to elaborate etching (etching) it is difficult to reflect heterogeneous colors in the pattern.

On the other hand, in another example of the manufacturing method of the conventional cladding accessories, in order to solve the above problems, a manufacturing method of forming a metal layer on the body of the appendage, and etching the pattern on the metal layer using a laser marking is disclosed.

However, the etching method using the laser marking has an advantage of easily processing various patterns, but for etching, the pattern body is fixed by fixing the accessory body to a jig and then laser marking on the flat plate (upper and lower surface) of the accessory body. Because of this, there was a problem that the coating on the side (side fixed with a jig) of the accessory body is difficult. That is, the etching on the front and rear surfaces of the attachment body was easy, and there was a problem that the etching on the side fixed with the jig was difficult.

The present invention has been devised to solve the above problems, by complementing the difficulty of etching the side surface of the accessory by laser etching the patterning process in the manufacturing process of the conventional coating accessories, and the pattern of the coating accessories It is an object of the present invention to provide a method for manufacturing a coating accessory that can add a double color and further improve the aesthetics while improving the manufacturing process.

According to a first embodiment of the present invention for achieving the above object, a first coating layer forming step of coating a coating on the body of the accessory; A surface planarization step of planarizing the first coating layer formed in the first coating layer forming step through a grinding operation; A metal layer forming step of forming a metal layer by coating a metal material on the planarized accessory body; A partial coating step of partially coating a predetermined pattern on a part of the plane of the metal layer by using a flatbed printer; Etching to form a metal pattern by exposing the appendage body to an etching solution to etch it over the entirety of the appendage body except for the coating portion; And providing a second coating layer forming step of coating and reinforcing a coating agent on the attachment body.

The metal layer forming step may be performed by depositing at least one of nickel, chromium, aluminum, and gold on the accessory body by vacuum deposition.

The coating agent may be at least one selected from the group consisting of UV (ultraviolet) coating liquid, enamel coating liquid, and meracoat coating liquid.

The etching solution may be at least one selected from the group consisting of arsenic solution, ferric chloride solution, and caustic soda solution.

Prior to the partial coating step, an etching step using laser marking for the etching of the elaborate pattern can be further carried out.

On the other hand, according to a second embodiment of the present invention, the first coating layer forming step of coating a coating on the body of the accessory; A metal layer forming step of forming a metal layer by coating a metal material on the accessory body; A pattern coating layer forming step of completely or partially covering a metal material having at least one color on a part of the surface of the metal layer by using a flatbed printer; Etching the metal layer and the pattern coating layer in a predetermined pattern through laser marking; And a second coating layer forming step of coating and reinforcing a coating agent on the etched accessory body. After the etching step, the chemical etching step of etching the side surface of the accessory body by exposing the accessory body to an etching solution is performed. It provides a method for producing a coating accessory comprising a further.

The metal layer forming step may be performed by depositing at least one of nickel, chromium, aluminum and gold on the accessory body by vacuum deposition, and the pattern coating layer may be coated with at least one heterogeneous metal different from the color of the metal layer. .

According to the present invention, in order to form a metal pattern on the coating accessory, the metal layer can be partially coated in a predetermined pattern and a chemical etching process can be performed, so that etching is performed only by conventional laser marking, so that etching on the side of the accessory is performed. Difficult to solve the process and troublesome process of etching the front and rear surfaces of the accessory separately, there is an effect that can further improve the production efficiency.

In addition, it is possible to easily coat a heterogeneous (different color) metal pattern on the coating accessory through a flatbed printer, thereby improving the aesthetics by adding a plurality of colors to the accessory. In addition, the pattern coating using a flat-panel printer and the etching (etching) through the laser marking in parallel has the effect of improving the process efficiency.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

2 is a process flowchart showing a manufacturing method of the coating accessory according to the first embodiment of the present invention.

First, to prepare a body of the accessory to form a metal pattern, the material of the accessory may be a variety of materials such as metal, plastic, mother-of-pearl, coconut (nut) or horn (horn).

Then, to form a first coating layer on the body of the prepared accessory (S 10; forming the first coating layer). The first coating layer may be a UV (ultraviolet) coating solution, enamel (enamel) coating liquid, a mera coat coating liquid and the like. The first coating layer serves to smooth the surface of the attachment body. As a result, the surface is not smooth, thereby preventing the deposited metal layer from being separated later. In addition, the deposition is evenly deposited on the attachment body in a later process. In this case, an additional planarization operation may be added through the grinding operation after the formation of the first coating layer.

Next, a metal material is deposited on the body of the accessory coated with the first coating layer (S 20; forming the metal layer). In this case, at least one of nickel, chromium, aluminum, or gold may be applied as the metal material. In addition, as an example of metal deposition, a resistance heating vacuum deposition method may be employed.

As described above, partial coating is performed on the attached body on which the metal material is deposited in a predetermined pattern (S 30; partial coating step). In this case, a flatbed printer may be employed to effectively partially coat a fine pattern. Accordingly, when an operator inputs a pattern (pattern such as lettering or pattern) into the flatbed printer, the head of the flatbed printer precisely applies the coating liquid based on the inputted pattern. In this case, the reason for the partial coating is to form a specific pattern on the body of the accessory by protecting the portion to be a pattern in an etching process in the future by etching and removing the rest except the protective coating in the later etching (etching).

Next, the etching solution is exposed to the entire surface of the partially coated accessory by etching (S 40; etching step). Accordingly, the remaining metal layer except for the partial coating area coated with the predetermined pattern is etched by a chemical reaction, so that only part of the pattern of the protective coated metal layer remains in the body of the appendage (the remaining metal layer is etched and removed). Work can be done.

Thus, chemical etching can be made to allow etching of the desired area through a single immersion solution, without the need to separately etch the front and back of the appendage. In particular, it is possible to solve the problem that the etching on the side that was conventionally generated in the etching process through laser marking is difficult. In this case, as the etching solution, one selected from the group consisting of an arsenic solution, a ferric chloride solution, and a caustic soda solution used in an etching process for a conventional nonferrous metal may be applied. In this case, an etching step using a laser marking for etching a fine pattern may optionally be further performed before the partial coating step S 30. This may optionally be done if a sophisticated patterning (lettering or patterning) process is required.

In the next process, the reinforcing coating is coated on the body of the etched appendage (S 50; second coating layer step). Accordingly, the metal pattern can be protected from external physical factors. In this case, as the reinforcing coating agent, the same coating liquid as that applied to the first coating layer (that is, UV, enamel, a Meracoat solution, etc.) may be applied.

Through such a series of processes, it is possible to significantly simplify the etching process in the related art, and in particular, when the metal pattern is formed, the metal pattern can be formed without inverting the front and rear surfaces of the body of the accessory, thereby forming processing performance and processing time. Can shorten.

Second Embodiment

Figure 3 is a process flow chart showing a manufacturing method of the coating accessory according to a second embodiment of the present invention, Figure 4 is an exemplary view showing a process state of the accessory body according to a second embodiment of the present invention.

First, to prepare the body 30 of the accessory to form a metal pattern, the material of the accessory may be a variety of materials such as metal, plastic, mother-of-pearl, coconut (nut) or horn (horn).

Then, to form a first coating layer on the body of the prepared accessory (S 10; forming the first coating layer). The first coating layer may be a UV (ultraviolet) coating solution, enamel (enamel) coating liquid, a mera coat coating liquid and the like. The first coating layer serves to smooth the surface of the attachment body. As a result, the surface is not smooth, thereby preventing the deposited metal layer from being separated later. In addition to this, the deposition is evenly deposited on the attachment body in a later process. In this case, an additional planarization operation may be added through the grinding operation after the formation of the first coating layer.

Part of the surface of the metal layer 32 is coated with a metal material having at least one color (pattern coating layer forming step; S 30). In this case, the coated metal material may be a heterogeneous metal material having a color different from that of the metal layer 32. Accordingly, a heterogeneous metal layer (pattern coating layer) 31 is formed on the body 30 of the accessory as shown in FIG. 4. In this case, a flatbed printer may be employed to effectively partially coat a fine pattern. As a result, the operator inputs a pattern (pattern such as lettering or pattern) into the flatbed printer, and the head of the flatbed printer can accurately coat the pattern coating layer 31 based on the input pattern.

In this case, the pattern coating layer 31 may be applied to the entire surface of the metal layer 32 or may be provided on a part of the metal layer 32 (which may be divided into a plurality of regions). In addition, the reason for forming the pattern coating layer 31 is to increase the aesthetics of the accessory by causing different colors to appear in the accessory. Therefore, the pattern coating layer may be coated by dividing into multiple regions having various colors.

Next, the metal layer 32 and the pattern coating layer 31 are etched in a predetermined pattern through laser marking (etching step S 40). The pattern 35 formed therein (which may be letters or patterns) may have different colors. That is, the colors of the metal layer 32 and the pattern coating layer 31 may appear to the outside, thereby improving the aesthetics of the product (coating accessory).

At this time, the etching step (S 40) may be performed in parallel with the partial etching through the laser marking, and the entire etching including the side of the body 30 of the accessory through the etching solution.

That is, etching may be performed by exposing the etching solution to the entire body of the accessory (S 45; chemical etching step). Thereby, the metal layer 32 with respect to the side surface of the attachment body 30 can be etched by a chemical reaction, and the effect of highlighting the pattern 35 can be expected. Thus, chemical etching is performed to allow etching of desired areas through one immersion of the solution, without the need to separately etch the front and back surfaces of the accessory. Accordingly, it is possible to solve the problem that the etching of the side surface raised in the etching process through the conventional laser marking is difficult.

In this case, as the etching solution, one selected from the group consisting of an arsenic solution, a ferric chloride solution, and a caustic soda solution used in an etching process for a conventional nonferrous metal may be applied.

In the next step, the reinforcing coating is coated on the body 30 of the etched appendage (S 50; second coating layer step). Accordingly, the metal pattern can be protected from external physical factors. In this case, as the reinforcing coating agent, the same coating liquid as that applied to the first coating layer (that is, UV, enamel, a Meracoat solution, etc.) may be applied.

Through such a series of processes, it is possible to significantly simplify the etching process conventionally, and in particular, when forming a metal pattern, different colors may be added to the pattern (for example, 35), thereby improving the aesthetics of the appendages. As a result, the time required for the process can be shortened, thereby improving productivity.

Although the present invention has been illustrated and described with respect to specific embodiments thereof, the present invention is not limited to the above-described embodiments, and a person skilled in the art to which the present invention pertains has the present invention described in the following claims. Various changes may be made without departing from the spirit of the technical idea of the invention.
