Abstract

The present invention relates to an electrostatic powder coating method for applying a paint to the surface of an object to be coated and, more specifically, to an electrostatic powder coating method, in which the thickness of a coating layer is constant while accurately and firmly applying various colors and patterns to the surface of an object to be coated by using a masking tape, thereby providing a smooth surface and a clean connection part of the coated surface. According to the present invention, a multi-pattern/color electrostatic powder coating method applies various colors and patterns to the surface of an object to be coated in an electrostatic powder coating method by using a masking tape and curing a coating layer at low temperature, thereby preventing deterioration of the state of the coated surface by the masking tape. Since the colors and patterns become accurate and firm by final high-temperature curing, a paint does not fall off from the coated surface and the thickness of the coated layer is constant, thereby providing a smooth surface and a clean connection part of the coated surface.

앞에서 설명한 바와 같이 본 발명의 일실시예인 다중무늬색상의 정전분체도장방법에 의하면, 마스킹테이프를 이용하여 다양한 색상과 무늬를 정전분체도장방법으로 피도물의 표면에 도포한 후 저온경화시킴으로써 상기 마스킹테이프에 의한 도포면 상태의 악화를 방지할 수 있고, 최종적으로 고온경화하여 상기 색상과 무늬를 정확하고 견고하게 함으로써 도료가 도포면으로부터 떨어지지 않을 뿐만 아니라 도포층의 두께가 일정하여 표면이 매끄럽고 도포면의 연결부위가 깨끗하게 되는 뛰어난 효과가 있다.As described above, according to the electrostatic powder coating method of multi-pattern color, which is an embodiment of the present invention, various colors and patterns are applied to the surface of the object by the electrostatic powder coating method using a masking tape and then cured at a low temperature to the masking tape. It is possible to prevent deterioration of the condition of the coated surface due to It has an excellent effect.

제1도는 본 발명의 일실시예인 다중무늬색상 정전분체도장방법에 따라 다중무늬색상으로 도포된 도포면을 도시한 부분정면도.제2도는 제1도의 도포면의 단면을 도시한 부분단면도.제3도는 본 발명의 일실시예인 다중무늬색상 정전분체도장방법에 따라 도료가 도포된 방화문 등의 피도물을 도시한 정면도.1 is a partial front view showing the coated surface coated with multi-pattern color according to the multi-pattern color electrostatic powder coating method, which is an embodiment of the present invention. A front view showing an object such as a fire door coated with paint according to the multi-pattern color electrostatic powder coating method according to an embodiment of the present invention.

본 발명은 도료를 피도물(被塗物)의 표면에 도포하는 정전분체도장방법에 관한 것으로서, 더욱 상세하게는 마스킹테이프를 이용하여 피도물의 표면에 다양한 색상과 무늬를 정확하고 견고하게 도포시키면서도 도포층의 두께가 일정하여 표면이 매끄럽고 도포면의 연결부위가 깨끗한 정전분체도장방법에 관한 것이다. 분체도료의 도장방법은 유동침적법, 정전유동침적법, 정전분체도장법등 여러 가지가 있으나 일반적으로 정전분체도장방법이 가장 많이 이용되고 있다. 정전분체도장(electrostatic powder painting)이라 함은 분무기로 도료를 분출하고 무화상태로 된 미립자를 정전유도작용으로 대전시킴으로써 발생하는 인력에 의하여 피도물의 표면에 흡착시키는 방법으로서,도포면에 기포가 없고 도료의 손실이 적어서 널리 이용되고 있다.그러나, 상기 정전분체도장방법은 각기 다른 무늬와 색상을 액체도장이나 스크린인쇄처럼 자유롭게 나타낼 수 없다는 문제점이 있었다.따라서, 정전분체도장방법에 의하여 도어 등의 피도물에 여러 가지 색상과 무늬를 나타낼 때에는 먼저 피도물의 표면에 바탕색을 고르게 정전분체도장한 다음, 그 상부에 원하는 무늬와 색상으로 인쇄된 필름을 부착하는 스크린인쇄법이 사용되었다.그러나, 상기의 방법은 인쇄면이 정확하고 깨끗한 장점은 있으나, 고급스럽지 못할 뿐만 아니라 시간이 경과함에 따라 부착이 부정확해지고 견고하지 못하며 쉽게 손상되는 몬제점이 있었다.또한, 다른 방법으로 피도물의 표면에 일정 무늬의 색상으로 먼저 분체도장하고 상기 도포면에 마스킹테 이프를 붙인 후, 상기 마스킹테이프를 붙이지 않은 표면에 원하는 다른 색상의 도료로 분체도장하여 건조로(baking oven)에서 도료가 용해 및 도막화되는 온도까지 가열한 다음 상기 마스킹테이프를 떼어내는 마스킹테이프법이 사용되었다.그러나, 상기의 방법은 마스킹테이프의 시저(seizure, 녹아붙음) 온도보다 도료의 용해 및 도막화 온도가 높아서, 도료가 용해되어 도막을 형성할 때까지 가열할 경우 상기 마스킹테이프가 먼저 분체도장된 도포면에 고착되어 떼어내기가 어려울 뿐만 아니라 떼어낸다하더라도 분체도장된 도료와 함께 떨어지게 되므로, 상기 마스킹테이프와의 경계부분이 깨끗하지 못하여 미관을 해치게 되는 문제점이 있었으며, 더욱이,도료의 용해 및 도막화과정에서 도포면이 마스킹테이프를 감싸고 경화되기 때문에 정전분체도장법을 이용할 수 없다는 문제점이 있었다.The present invention relates to an electrostatic powder coating method for applying a paint to the surface of an object to be coated, and more particularly, to a coating layer while accurately and firmly applying various colors and patterns to the surface of an object using a masking tape. It relates to an electrostatic powder coating method with a uniform thickness, a smooth surface, and a clean connection part of the coated surface. There are several coating methods for powder coatings, such as flow dipping, electrostatic fluid immersion, and electrostatic powder coating, but in general, electrostatic powder coating is the most used. Electrostatic powder painting is a method of adsorbing paint to the surface of the object by the attractive force generated by ejecting the paint with a sprayer and charging the atomized fine particles by electrostatic induction. However, the electrostatic powder coating method has a problem in that different patterns and colors cannot be freely expressed like liquid painting or screen printing. When displaying eggplant colors and patterns, a screen printing method was used in which the ground color was first evenly coated with electrostatic powder on the surface of the object, and then a film printed with the desired pattern and color was attached to the upper part. However, the above method Although this has the advantage of being accurate and clean, it is not luxurious, and there are monje points that are inaccurate, not sturdy, and easily damaged as time goes by. After attaching the masking tape to the coated surface, powder coating the surface to which the masking tape is not attached is coated with a paint of a different color desired, heated in a baking oven to a temperature at which the paint is dissolved and coated, and then the masking tape The peeling masking tape method was used. However, in the above method, the dissolution and coating temperature of the coating material is higher than the seizure temperature of the masking tape. Since the masking tape is first adhered to the powder-coated coating surface and is difficult to remove, and even if removed, it falls off together with the powder-coated coating material. , There was a problem that the electrostatic powder coating method could not be used because the coated surface was wrapped around the masking tape and cured during the dissolution and coating process of the paint.
