Ultraviolet (UV) coating, which is a coating method for hardening the coating film by ultraviolet energy, is used to improve the esthetics of the appearance design and to protect it from external impacts.

상기 유브이 코팅은 소재의 변형 없이 높은 에너지를 순간적으로 사출물에 조사함으로써 경도가 강한 도막을 형성시키게 되고, 이로 인하여 외관부품이 높은 광택도와 함께 스크래치가 방지되는 이점을 가지게 된다. The UV coating can form a coating film having high hardness by irradiating high-energy instantaneously to an injection material without deformation of the material, thereby having an advantage that the appearance component is prevented from being scratched with high gloss.

그러나, 상기와 같은 코팅방법은 공정의 소량화로 인하여 대량 생산이 어려운 문제점이 있으며, 높은 공정비로 인한 재료비의 인상 원인을 제공하게 되는 문제점이 있다. However, such a coating method has a problem that mass production is difficult due to a small amount of the process, and there is a problem that the material cost is increased due to a high process ratio.

또한, 사출물에 형성된 유브이 코팅층의 경도가 매우 높아 코팅층 상부에 문자나 숫자 등의 스탬핑(Stemping) 작업이 원활하게 이루어지지 않는 문제점이 있다.In addition, since the hardness of the uv coating layer formed on the injection molded article is very high, there is a problem that stamping work such as letters and numbers is not smoothly performed on the coating layer.

뿐만 아니라, 유브이 코팅의 경우 유색 구현이 어려운 문제점이 있다.In addition, there is a problem that it is difficult to realize the colored coating in the case of the UV coating.

이하에서는 본 발명에 의한 사출물 코팅방법에 대하여 첨부된 도면을 참조하여 상세히 설명한다.Hereinafter, a method of coating an injection-molded product according to the present invention will be described in detail with reference to the accompanying drawings.

도 1 에는 본 발명에 의한 사출물 코팅방법을 설명하기 위한 플로우차트가 도시되어 있다.FIG. 1 is a flow chart for explaining an injection material coating method according to the present invention.

도면에 도시된 바에 의하면, 본 발명에 의한 사출물 코팅방법은 우선 투명도료에 코팅대상물인 사출물과 동일 색상의 유색안료를 혼합하는 단계(a)가 수행된다. [S100]As shown in the drawing, in the method of coating an injection-molded product according to the present invention, step (a) is first carried out for mixing an injection-molded object and a colored pigment of the same hue into a transparent paint. [S100]

이에 앞서 상기 코팅대상물은 사출 성형시 주재료인 레진에 특정색상을 부가하기 위하여 유색안료를 첨가하여 사출성형하게 되고, 이때 첨가되는 유색안료와 동일한 유색안료가 상기 투명도료에 혼합된다. Prior to this, the coated object is injection-molded by adding a colored pigment to add a specific color to the resin, which is a main material at the time of injection molding, and the same colored pigment as the colored pigment to be added at this time is mixed with the transparent paint.

상기 투명도료는 유성 바니시(Varnish), 셀락 바니시(Varnish), 투명래커(Clear lacquer), 합성 수지 바니시(Varnish) 등을 사용해서 투명한 도막층을 만드는 것으로 사출대상물의 색상과 동일한 색상의 유색안료를 상기와 같은 투명도료에 혼합하게 된다. The transparent paint is made of transparent varnish, varnish, clear lacquer, varnish or the like to form a transparent coating layer, which is made of a colored pigment having the same color as that of the object to be injection molded It is mixed with the transparent coating material as described above.

그리고, 상기 단계(a)를 수행한 이후에는 상기 코팅대상물에 단계(a)에서 형성된 유색안료와 투명도료가 혼합된 혼합도료를 코팅대상물에 도포하는 단계(b)가 수행된다. [S200]After the step (a) is performed, a step (b) of applying a mixed paint, which is a mixture of a colored pigment and a transparent paint, formed in step (a) to the coating object is performed on the coated object. [S200]

즉, 상기 단계(b)에서는 단계(a)에서 형성된 혼합도료를 스프레이건과 같은 분사수단에 장입하고, 장입된 혼합도료를 코팅대상물에 분사함으로써, 코팅대상물의 표면에 혼합도료로 구성되는 얇은 코팅층을 형성하게 된다. That is, in the step (b), the mixed paint formed in step (a) is charged into a spraying means such as a spray gun, and the mixed paint to be charged is sprayed onto the object to be coated so that a thin coating layer .

한편, 상기와 같이 코팅대상물에 혼합도료에 의한 코팅층의 형성이 완료되면 상기 코팅대상물을 건조시키는 단계(c)가 수행되며, 상기 단계(c)는 상온에서 수행된다. [S300]Meanwhile, when the formation of the coating layer by the mixed paint is completed on the coating object as described above, the step (c) of drying the coating object is performed, and the step (c) is performed at room temperature. [S300]

이하에서는 상기와 같은 본 발명에 의한 사출물 코팅방법에 관하여 냉장고용 사출물에 적용된 일실시 예를 통해 상세히 설명하기로 한다.Hereinafter, the method of coating an injection-molded product according to the present invention will be described in detail with reference to an embodiment applied to an injection molding for a refrigerator.

도 2 에는 본 발명에 의한 사출물 코팅방법이 채용된 냉장고의 사출물 코팅과정을 설명하기 위한 플로우차트가 도시되어 있고, 도 3 에는 본 발명에 의한 사출물 코팅방법이 적용된 냉장고용 사출물의 외관을 도시한 사시도가 도시되어 있으며, 도 4 에는 도 3 의 A-A′부 단면도가 도시되어 있다.FIG. 2 is a flowchart illustrating an injection molding process of a refrigerator employing an injection molding method according to the present invention. FIG. 3 is a perspective view illustrating an appearance of an injection molding for a refrigerator to which an injection molding method according to the present invention is applied. And FIG. 4 is a sectional view taken along line AA 'of FIG.

이하에서는 본 발명의 일실시 예로 검정 색상의 냉장고의 디스펜서 일측에 구비되는 사출물을 일 예로 설명을 전개해 나가도록 한다.Hereinafter, an embodiment of the present invention will be described with reference to an example of an ejector provided on one side of a dispenser of a black color refrigerator.

도면에 도시된 바와 같이 본 발명에 의한 냉장고용 사출물(100)을 코팅하는 과정에서는 우선, 냉장고용 사출물(100) 본체(120)의 색상인 검정색의 안료를 투명도료에 혼합하게 된다. As shown in the drawing, in the process of coating the injection mold 100 for a refrigerator according to the present invention, black pigment of the color of the main body 120 of the injection mold 100 for a refrigerator is mixed with the transparent paint.

상기와 같이 투명도료에 혼합되는 검정색 안료는 투명도료에 비해 상대적으로 매우 적은 양이 혼합되므로 검정색 안료가 투명도료에 혼합되더라도 투명도를 유지할 수 있게 된다. As described above, since the black pigment to be mixed with the transparent paint is mixed with a relatively small amount as compared with the transparent paint, transparency can be maintained even when the black pigment is mixed with the transparent paint.

그리고, 상기와 같이 검정색 안료가 혼합된 투명도료는 상기 본체(120)의 외주면에 고르게 도포되며, 필요에 따라 외부로 드러나는 부분에만 혼합된 투명도료를 도포하는 것도 가능할 것이다. The transparent paint mixed with the black pigment as described above is evenly applied to the outer circumferential surface of the main body 120, and if necessary, it is also possible to apply the transparent paint mixed only to the portion exposed to the outside.

즉, 도 3 에 도시된 냉장고용 사출물(100)은 냉장고의 도어에 구비되는 디스펜서의 조작부로 중앙 부분에 디스플레이 화면이 수용되는 부분이 천공 형성되고, 그 외측으로 다수의 조작버튼이 수용되는 부분이 천공되도록 본체(120)가 형성된다.That is, the injection mold 100 for a refrigerator shown in FIG. 3 is an operation part of a dispenser provided in a door of a refrigerator, and a part where a display screen is received is formed at a central part thereof, The body 120 is formed to be perforated.

그리고, 상기 본체(120)는 사출성형시 주재료인 레진에 검정색 안료를 첨가하여 본체가 전체적으로 검정색을 띄도록 형성된다.The main body 120 is formed by adding black pigment to resin, which is a main material at the time of injection molding, so that the main body 120 is entirely black.

한편, 상기와 같이 형성된 냉장고용 사출물(100)의 본체(120)는 전면(前面)만 외부로 드러나게 되므로 전체적으로 상기 검정색 안료가 혼합된 투명도료를 도포할 필요가 없으므로 전면(前面)에만 상기 검정색 안료가 혼합된 투명도료를 도포하게 된다. Since only the front surface of the main body 120 of the molded article for a refrigerator 100 formed as described above is exposed to the outside, it is not necessary to apply the transparent paint mixed with the black pigment as a whole, so that the black pigment Is coated on the transparent coating material.

그리고, 상기와 같이 냉장고용 사출물(100)의 전면(前面)에 검정색 안료가 혼합된 투명도료의 도포가 완료되면 상온에서 상기 냉장고용 사출물(100)을 건조시켜 냉장고용 사출물(100)의 제조가 완료되며, 이와 같이 제조 완료된 냉장고용 사출물(100)은 도 4 에 도시된 바와 같이 검정색 안료와 투명도료의 혼합코팅층(140)을 가지게 된다.When the transparent paint mixed with the black pigment is applied to the front surface of the injection molded article 100 for a refrigerator as described above, the injection molded article 100 for the refrigerator is dried at room temperature, As shown in FIG. 4, the injection molded article 100 for a refrigerator thus completed has a mixed coating layer 140 of a black pigment and a transparent paint.

이하에서는 상기와 같은 본 발명의 작용에 대하여 설명한다. Hereinafter, the operation of the present invention will be described.

본 발명은 코팅대상물의 색상과 동일한 색상의 유색안료를 투명도료에 혼합하여 코팅대상물에 도포함으로써 코팅대상물의 외주면에 혼합코팅층을 형성하게 된다. The present invention forms a mixed coating layer on the outer circumferential surface of a coating object by mixing a color pigment having the same hue as the color of the coating object with a clear coating material and applying the mixture to the coating object.

이때, 상기와 같이 도포되는 유색안료와 투명도료의 혼합액은 스프레이건과 같은 분사수단에 장입되어 도포 되므로 기술적으로 별다른 어려움 도포 공정이 이루어지게 된다. At this time, since the mixed liquid of the colored pigment and the transparent paint to be applied as described above is charged into the spraying means such as the spray gun and is applied, technically a difficult coating process is performed.

그리고, 상기와 같이 투명도료에 혼합되는 유색안료는 코팅대상물인 사출물의 사출성형시 포함되는 유색안료와 동일한 색상으로, 사출물에 이와 같은 유색안료가 혼합된 투명도료를 도포하게 되면 사출물의 색상이 보다 선명해지고 광택이 두드러지게 된다. The colored pigments mixed in the transparent paint as described above have the same hue as the colored pigments contained in the injection molding of the injection molded article and when the transparent paint mixed with the colored pigment is applied to the injection molded article, Sharpness and luster become noticeable.

상기와 같은 본 발명의 범위는 전술한 실시 예에 한정되는 것이 아니라 본 발명이 속하는 기술분야에 종사하는 통상의 기술자들에게 있어서는 본 발명을 기초로 하는 다른 많은 변경이 가능할 것이다.The scope of the present invention is not limited to the above-described embodiments, and many other modifications may be made by those skilled in the art to which the present invention pertains.

예를 들어 본 발명의 일 실시 예에서는 검정색 안료를 투명도료에 혼합하여 스프레이건을 통해 사출물에 분사되어 코팅층을 형성하는 것으로 설명하였으나, 사 출물의 색상에 따라 다양한 색상의 안료를 투명도료에 포함시켜 분사하는 것이 가능할 것이다.For example, in an embodiment of the present invention, a black pigment is mixed with a transparent paint and sprayed onto an injection material through a spray gun to form a coating layer. However, various colors of pigments may be included in the transparent paint depending on the color of the subject matter It will be possible to spray.
