CONSTITUTION: In the method to coat the door for the refrigerators having stainless touch which laminates a primer layer(104) on the surface of a metal steel sheet, a base layer(105), a printed layer(106) and a clear layer(107) on the surface of the printed layer orderly from the lower prime layer, the printed layer is formed by the steps of: (i) letting silver metal print on the surface of the layer by one color; (ii) letting gold metal print on the printed surface by two colors to adjust color and magnification; and (iii) allowing a printing roll to form a hair line(111) for having the printed layer get stainless touch.

Description

스테인레스 질감을 가지도록 하는 냉장고 도어의 도장방법{PAINTING METHOD OF REFRIGERATOR DOOR}Coating method of refrigerator door to have stainless texture {PAINTING METHOD OF REFRIGERATOR DOOR}

본 발명은 냉장고 도어의 도장방법에 관한 것으로, 특히 미세한 실버와 골드의 금속입자를 차례로 인쇄함과 아울러 헤어라인 처리하여 저비용으로 스테인레스 질감이 느껴지도록 하는 냉장고 도어의 도장방법에 관한 것이다.The present invention relates to a coating method of a refrigerator door, and more particularly, to a coating method of a refrigerator door to print a fine silver and gold metal particles in sequence and to process a hairline to feel a stainless texture at low cost.

도 1과 도 2에 도시된 바와 같이, 종래 일반적인 형태의 냉장고는 냉동실과 냉장실이 형성되어 있는 본체(1)와, 그 본체(1)의 냉동실과 냉장실의 전방 개구부에 개폐가능하도록 도어(2)가 각각 설치되어 있다.As shown in Fig. 1 and Fig. 2, the conventional general type refrigerator includes a main body 1 in which a freezing compartment and a refrigerating compartment are formed, and a door 2 so as to be opened and closed in the front openings of the freezing compartment and the refrigerating compartment of the main assembly 1. Are installed respectively.

그리고, 상기와 같이 도어(2)의 표면에는 다양향 색상으로 도장이 되어 있는데, 도 3을 참조하여 도장구조를 살펴보면 다음과 같다.And, as described above, the surface of the door 2 is painted in a variety of colors, looking at the coating structure with reference to Figure 3 as follows.

강판 재질로된 소재(10)의 후면에는 후면에 내식성을 위한 도색층(11)이 형성되어 있고, 그 소재(10)의 전면에는 부착성을 갖도록 프리퍼층(12)이 형성되어 있고, 그 프리머층(12)의 상면에는 기계적 화학적 물성이 유지되도록 과 베이스층(13)이 차례로 형성되어 있다.On the back side of the material 10 made of steel, a paint layer 11 for corrosion resistance is formed on the back side, and on the front side of the material 10, a preper layer 12 is formed to have adhesion. The upper layer 13 is sequentially formed on the upper surface of the mer layer 12 so as to maintain the mechanical and chemical properties.

또한, 상기 베이스층(13)의 상면에는 소정색상과 무늬를 가지는 프린트층(14)이 형성되어 있고, 그 프린트층(14)의 상면에는 그 프린트층(14)을 보호함과 아울러 미려한 외관질감을 갖도록 하기 위하여 클리어층(15)이 형성되어 있으며, 그 클리어층(15)의 표면에는 운동 및 취급시 손상되는 것이 방지되도록 보호비닐(16)이 부착되어 있다.In addition, a print layer 14 having a predetermined color and a pattern is formed on an upper surface of the base layer 13, and a beautiful appearance texture while protecting the print layer 14 on an upper surface of the print layer 14. A clear layer 15 is formed to have a surface, and a protective vinyl 16 is attached to the surface of the clear layer 15 to prevent damage during movement and handling.

상기와 같은 종래의 도장구조에서는 강판 소재(10)의 후면에 도색층(11)을 형성함과 아울어 전면에는 프리머를 도포하여 프리머층(12)을 형성하고, 그 프리머층(13)의 상면에 소정 색상과 무늬를 인쇄하여 프린트층(14)을 형성한다.In the conventional coating structure as described above, the primer layer 12 is formed by applying a primer on the front surface of the steel plate material 10 and forming a primer layer 12 on the front surface of the primer layer 13. The print layer 14 is formed by printing a predetermined color and pattern on the upper surface.

그런후, 그 프린트층(14)의 상면에 클리어층(15)를 형성한 후, 표면에 보호비닐(16)을 부착하여 도장층이 보호되도록 한다.Then, after the clear layer 15 is formed on the upper surface of the print layer 14, a protective vinyl 16 is attached to the surface to protect the coating layer.

그러나, 상기와 같은 종래 냉장고 도어의 도장방법으로는 고급스럽고 다양한 무늬의 구현이 어려우며, 특히 최근 각광받고 있는 스테인레스 질감의 무늬를 구현하는 것이 불가능한 문제점이 있었다.However, the coating method of the conventional refrigerator door as described above has a problem that it is difficult to implement a luxury and various patterns, in particular it is impossible to implement a pattern of stainless texture, which has recently been spotlighted.

상기와 같은 문제점을 감안하여 안출한 본 발명의 목적은 금속입자를 이용한 간단한 도장처리로 고급스런 스테인레스 질감이 나도록 하는데 적합한 스테인레스 질감을 가지도록 하는 냉장고 도어의 도장방법을 제공함에 있다.An object of the present invention devised in view of the above problems is to provide a coating method of a refrigerator door to have a stainless texture suitable for producing a high quality stainless texture by a simple coating treatment using metal particles.
