본 발명은 아연피막이 형성된 주철 가로등주 표면에 분체도료를 코팅하는 분체도장 방법에 관한 것으로 보다 구체적인 것은 구상흑연 주철제 가로등주를 아연용융액 속에 담구어 구상흑연 주철등주의 표면에 아연용융액을 일정 두께로 피복시키고 인출하여 고화시켜 아연피막이 형성되게 한 공지의 주철 가로등주 표면에 분체도료를 확고하게 코팅시켜서 녹을 완전히 방지하고 미관을 좋게 하는 분체 도장 방법이다.The present invention relates to a powder coating method for coating a powder coating on the surface of cast iron street lamps with zinc coating, and more specifically, to immerse the spherical graphite cast iron street lamps in a zinc molten coating to cover the surface of the spherical graphite cast iron with a certain thickness and withdrawal. It is a powder coating method that completely prevents rust and improves aesthetics by firmly coating a powder coating on a surface of a known cast iron street lamp which solidified by forming a zinc coating.

아연피막은 주철가로등주의 녹을 방지하기 위해 실시하는 방청수단의 하나로 사용되고 있으나 파이프로 된 가로등주의 표면에는 전기 도금에 의하여 아연피막을 형성하기 때문에 기공이 없는 도금이 가능하지만 주철제 등주는 표면요철과 기공이 많아 전기도금을 하는 것이 어렵기 때문에 아연용탕액에 주철제 등주를 담구었다가 인출하는 방법으로 아연피막을 형성하기 때문에 아연피막이 균일하게 피복되지 아니하고 많은 기공이 형성되어 이를 매꾸어야 하는 문제가 있고 색상이 백색이므로 미관을 보완하기 위해 도색을 해야 하는 문제가 있다. Zinc coating is used as one of the rust preventive measures to prevent rust of cast iron street lamps. However, since the zinc coating is formed by electroplating on the surface of street lamps made of pipes, plating is possible without pores. Since it is difficult to do electroplating, zinc coating is formed by dipping cast iron column in zinc molten metal and drawing it. Therefore, zinc coating is not uniformly coated and many pores are formed to make up the problem. White, there is a problem that must be painted to complement the aesthetics.

그러나 아연피막 표면에는 페인트가 견고하게 부착되지 않기 때문에 도색후 쉽게 벗겨져서 수명이 오래가지 못하는 문제가 있다.However, since the paint is not firmly attached to the surface of the zinc coating, there is a problem that the paint is peeled off easily and the life does not last long.

본 발명은 위와 같은 종래의 문제점을 개선하기 위해 발명된 것이다.The present invention has been invented to improve the above conventional problems.

본원 출원인은 발명특허 제115114호로 아연피막이 형성된 주철 가로등주의 표면에 분체 도장을 실시하기 위해 미세요철면을 형성하는 장치에 대한 특허권을 가지고 있고 발명특허 제452483호로 주철 가로등주의 표면에 분체 도장을 코팅하는 방법을 개발하여 도장수명이 오래가는 가로등 등주를 얻을 수 있게 한 발명특허를 가지고 있으나 아연피막이 형성된 주철 가로등표면에 분체도장을 실시하기 위해서는 상기 발명을 개선한 방법이 필요하게 된다.Applicant has the patent right to the apparatus for forming the fine iron surface to apply the powder coating on the surface of the cast iron street lamp of the zinc coating formed by the invention patent No. 115114 and the method of coating the powder coating on the surface of the cast iron street lamp by the invention patent No. 452483 Although the invention has a patent to obtain a long-lasting street lamps, the coating life is long, but in order to apply the powder coating on the surface of the cast iron street lamps with zinc coating, there is a need to improve the invention.

Way.

한편, 본 발명에서 아연피막이 형성된 주철제 가로등주 표면에 미세요철을 형성하는 타격장치는 통상의 샌드처리와는 판이하게 스틸볼을 사용하여 아연피막 표면을 0.4~2mm 크기의 스틸볼로 타격하여 아연피막의 표면에 미세요철을 형성하고 이물질을 제거한다.On the other hand, in the present invention, the blow device for forming a fine iron on the surface of the cast iron street lamp made of zinc coating is different from the conventional sand treatment using a steel ball to hit the surface of the zinc coating with a steel ball of 0.4 ~ 2mm size of the zinc coating It forms fine irregularities on the surface and removes foreign substances.

이를 위해 본 발명은 외부와 격리되게 만든 타격실(10)내에 소재장치통(11)을 내장하여 현가시키고 회전시키면서 소재장치통 회전장치(11a)로서 회전시키고 그 속에 소재를 넣어 표면에 0.4~2mm 크기로 된 스틸볼을 타격팬(12)으로 20~30분간 타격함으로써 분체 도료코팅에 필요한 미세요철을 소재표면에 균등하게 형성시키고 이물질을 제거하여 분체도장에 필요한 미세요철을 형성하게 된다.To this end, the present invention is built into the batting chamber (10) made to be isolated from the outside and suspended and rotated while rotating as a material device rotating device (11a) and put the material therein 0.4 ~ 2mm By hitting the steel ball of the size with a blow fan 12 for 20 to 30 minutes to form a fine roughness required for powder coating coating on the material surface and to remove foreign substances to form a fine roughness required for powder coating.

또, 본 발명은 스틸볼의 타격으로 미세홈이 형성된 소재를 브로워 세척기에 투입하여 청소한 다음 가열실에 넣어 120~150℃에서 20~30분간 가열함으로써 소재에 잠재된 수분을 소증시킬 수 있고 이로 인해 아크릴우레탄 페인트를 20~50미크론 두께로 코팅할 때 효과적인 예비 도색이 가능하며 이때에는 집진시설과 분무기가 구비된 보호막 형성용 페인트부스(4)를 이용함으로써 편리한 도색이 이루어진다.In addition, the present invention can clean the material formed with a fine groove by hitting the steel ball in the blower and then put it in the heating chamber to heat 20 to 30 minutes at 120 ~ 150 ℃ to quench the potential moisture in the material Due to this, when the acrylic urethane paint is coated with a thickness of 20 to 50 microns, an effective preliminary painting is possible. In this case, a convenient coating is achieved by using a protective booth forming paint booth (4) equipped with a dust collector and an atomizer.

이어서 분체 도료코팅부스에 투입하여 분체로된 폴리에스텔 접착성 분체 도료를 80~150 미크론 두께로 코팅하고 Subsequently, it was put into powder coating coating booth and coated the powdered polyester adhesive powder coating with 80 ~ 150 micron thickness.

코팅된 분체 도료를 220~280℃의 열기를 유지하는 오븐기(6) 속에 투입하므로서 분체도료를 녹여서 아연피막 표면에 접착시키고 인출하여 분체 도료를 응고시 킨 다음 그 피막을 보호하기 위한 아크릴우레탄 투명페인트를 40~80미크론 두께로 도포하는 보호코팅실(7)에서 도색함으로써 작업이 종료된다.Put the coated powder paint into the oven 6 which maintains the heat of 220 ~ 280 ℃, melt the powder paint, adhere it to the zinc film surface, take it out, coagulate the powder paint, and then protect the film. The work is terminated by painting in a protective coating chamber 7 applying 40 to 80 microns thick.

특히, 본 발명에 사용되는 오븐기(6)는 가열실(60 외측에 가스버너가 부착된 열풍발생기(61)가 장치되어 가열실에 열기를 공급하고 가열실내의 열기는 흡인관(62)으로 흡인하여 열풍발생기(61)로 보내 재가열하여 공급하는 장치로 가열실의 열기를 220~280℃로 유지할 수 있고 아연피막이 형성된 가로등주는 이송체인(8)에 매달아서 이용시킴으로써 연속작업이 가능하고 페인트부스와 타격기에는 집진설비를 장치하여 작업환경이 열약해지지 않도록 하여 작업을 하게 된다.In particular, the oven 6 used in the present invention is equipped with a hot air generator 61 having a gas burner on the outside of the heating chamber 60 to supply heat to the heating chamber, and the heat in the heating chamber is sucked into the suction pipe 62. It is a device that sends to the hot wind generator 61 and reheats and supplies it to maintain the heat of the heating room at 220 ~ 280 ℃, and the street lamps with zinc coating can be used by hanging them on the transfer chain 8 to enable continuous work. Paint booth and blower The dust collector is installed in the work environment so as not to weaken the work.

이와 같이 된 본 발명은 구상흑연 주철가로 등주의 표면에 아연피막이 형성된 등주소재를 스틸볼 타격장치에 투입하여 회전시키면서 스틸볼로 타격함에 따라 아연피막 전체에 분체 도료 코팅에 필요한 미세한 요철을 형성할 수 있으며 타격볼을 0.4~2mm의 스틸볼을 사용함으로써 아연피막의 근간을 훼손하지 않고 효과적으로 미세홈 형성이 가능케 되며 미세요철이 형성된 소재를 120~150℃로 가열하여 소증시킨 다음 보호막을 입혀서 분체 도장을 형성함으로써 아연피막 위에 분체도장의 접착을 확고하게 형성할 수 있고 분체도장이 형성된 표면에는 아크릴우레탄 투명 페인트로 된 보호피막을 형성함으로써 분체 도장면을 보호하므로 습기와 공기의 침투를 차단하여 분체코팅의 수명을 내구적으로 유지시키게 된다.The present invention as described above can form fine irregularities required for coating powder coating on the whole zinc coating as the steel ball hits the steel ball while rotating the isotropic material formed of zinc coating on the surface of the column with the spherical graphite cast iron street. By using the steel ball of 0.4 ~ 2mm, it is possible to form micro grooves effectively without damaging the foundation of zinc coating.It is heated by heating to 120 ~ 150 ℃ to form fine fine iron and then coated with a protective film to apply powder coating. It can form the adhesion of powder coating firmly on the zinc coating, and protect the powder coating surface by forming a protective film of acrylic urethane transparent paint on the surface where powder coating is formed, thus preventing the penetration of moisture and air. It will keep life long.

따라서 본 발명은 아연피막과 분체도료의 협동에 의하여 주철 가로등의 표면 보호를 더 확고하게 보호하므로 녹이 발생하는 것을 막을 수 있고, 아연피막 형성 단계에서 산처리, 수세, 후릭스 처리가 끝난 구상흑연 주철가로등주를 가열하여 소증시키기 때문에 기공속에 수분이 완전히 제거된 상태에서 아연용융액의 피막을 형성시키므로 아연피막이 견고하고 아연피막의 이완을 막을 수 있으며 미려한 가로등주를 제공할 수 있게 되는 이점이 있다.Therefore, the present invention can more firmly protect the surface protection of the cast iron street light by the cooperation of zinc coating and powder coating, thereby preventing rust from occurring. In the zinc film forming step, the acid treatment, water washing, and flix treatment of spheroidal graphite cast iron Since the street lamps are heated and steamed to form a film of zinc molten liquid in a state in which water is completely removed in the pores, the zinc film is firm and prevents the zinc film from being relaxed, thereby providing a beautiful street lamp.
