이하에서는 첨부도면을 참조하여 본 발명에 대해 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
도 1은 본 발명에 따른 도장강판의 부분단면도이고, 도 2는 본 발명에 따른 도장강판의 방향도장층의 단면도이다. 이들 도면에 도시된 바와 같이, 본 발명에 따른 도장강판(1)은, 소지강판(2)과, 소지강판(2) 위에 순차적으로 도포되는 합금도금층(3), 크롬산염층(4), 하도도장층(5)과, 상도도장층인 방향도장층(6)을 갖는다. 1 is a partial cross-sectional view of a coated steel sheet according to the present invention, Figure 2 is a cross-sectional view of the directional coating layer of the coated steel sheet according to the present invention. As shown in these figures, the coated steel sheet 1 according to the present invention, the steel plate 2, the alloy plating layer (3), the chromate layer (4), sequentially coated on the steel plate 2 It has the coating layer 5 and the directional coating layer 6 which is a top coat layer.
소지강판(2)은, 냉간압연강판, 용융아연도금강판, 전기아연도금강판, 알루미늄강판 등으로 다양하게 마련될 수 있으며, 여기서는, Al, Zn로 이루어지는 합금용융 도금 욕조 내에 소지강판(2)을 통과시켜 에어와이법에 의해 도금피복량을 조절하여, 소지강판(2) 상에 합금도금층(3)을 형성하게 된다. The holding steel sheet 2 may be variously provided as a cold rolled steel sheet, a hot dip galvanized steel sheet, an electrogalvanized steel sheet, an aluminum steel sheet, and the like. Here, the holding steel sheet 2 is placed in an alloy molten plating bath made of Al and Zn. By passing through to adjust the coating coating amount by the air wipe method, to form the alloy plating layer 3 on the base steel sheet (2).
합금도금층(3)의 표면에 존재하는 녹 유분, 먼지 등의 오염물을 알카리액을 이용하여 완전히 제거한 후, 롤코팅 방법을 이용하여 얇은 막으로 크롬산 염을 도포한 다음, 80 내지 120℃의 온도에서 건조시켜 함금도금층 위에 15 내지 45㎎/㎡의 크롬산염층(4)을 형성시킨다.Contaminants such as rust oil and dust present on the surface of the alloy plating layer 3 are completely removed by using an alkaline liquid, and then the chromic acid salt is coated with a thin film using a roll coating method, and then at a temperature of 80 to 120 ° C. By drying, a chromate layer 4 of 15 to 45 mg / m 2 was formed on the plating layer.
한편, 크롬산염층(4) 위에는 고분자 폴리에스테르 도막층이 형성되며, 폴리에스테르 도막층은, 하도인 하도도장층(5)과, 하도도장층(5) 위에 상도인 방향도장층(6)으로 2층 구조로 이루어진다. On the other hand, a polymeric polyester coating layer is formed on the chromate layer 4, and the polyester coating layer is the undercoat layer 5 which is the undercoat, and the aromatic coating layer 6 which is the top coat on the undercoat layer 5. It consists of a two-layer structure.
하도도장층(5)은, 건조도막두께는 4-8㎛로 크롬산염층(4) 위에 작업을 실시하나, 5-7㎛으로 작업하는 것이 바람직하며, 소부 온도는 216-224℃ (PMT; Pick Metal Temperature 기준)에서 실시하게 된다.The undercoat layer 5 works on the chromate layer 4 with a dry coating thickness of 4-8 μm, but preferably at 5-7 μm, and the baking temperature is 216-224 ° C. (PMT; Pick Metal Temperature).
또한, 하도도장층(5)은, 방향도장층(6)의 고분자 폴리에스테르 수지와의 소재 부착성 및 유연성을 유지시키기 위해서 부착성이 우수한 엑폭시수지를 브랜딩하고 폴리이소시네이트 수지를 가교제로 한 우레탄 수지를 결합함으로써, 하도도장층(5) 자체의 기본물성인 일반적인 내식성 및 방향도장층(6)과 도금강판과의 부착성 강화 외에 충분한 연신율을 부여하여, 가공시 발생되는 소재의 균열을 방향도장층(6)까지 전달되지 않고 흡수될 수 있도록 마련된다.In addition, in order to maintain the material adhesion and flexibility of the aromatic coating layer 6 with the polymeric polyester resin, the undercoat layer 5 is branded with an epoxy resin having excellent adhesion and a polyisocyanate resin as a crosslinking agent. By combining the urethane resin, it provides general corrosion resistance, which is the basic property of the undercoat layer 5 itself, and strengthens the adhesion between the aromatic coating layer 6 and the plated steel sheet, and provides sufficient elongation to prevent cracking of the material generated during processing. It is provided to be absorbed without being transferred to the coating layer (6).
방향도장층(6)은, 하도도장층(5)이 완전경화한 후 하도도장층(5) 위에 건조도막두께가 18-22㎛이 되도록 롤코팅 방식으로 도장한 후, 오븐에서 롤코팅 된 강판을 232-241℃ (PMT; Pick Metal Temperature 기준)로 가열하여 건조시킨다. The direction coating layer 6 is a steel sheet roll coated in an oven after coating the coating layer 5 is completely cured and coated on the coating layer 5 with a dry coating thickness of 18-22 μm. It is dried by heating to 232-241 ℃ (PMT; Pick Metal Temperature).
여기서, 상도도장층인 방향도장층(6)은 54.2중량%의 고분자 폴리에스테르수지, 33.2중량%의 안료, 5중량%의 멜라민수지, 향을 발생하는 물질을 함유한 5.6중량%의 방향입자, 2중량%의 폴리프로필렌계 왁스와 폴리아마이드계 왁스 중 어느 하나를 포함한다. Here, the fragrance coating layer 6, which is a top coat layer, is a 5.6 wt% fragrance particle containing 54.2 wt% polymer polyester resin, 33.2 wt% pigment, 5 wt% melamine resin, and a substance generating aroma, It comprises any one of 2% by weight of polypropylene wax and polyamide wax.
즉, 방향도장층(6)은 고분자 폴리에스테르 수지를 포함함으로써, 폴리프로필렌계의 안료입자에 의한 돌출형성 및 도료의 열경화 밀도 차이를 이용하여 2중의 입체질감을 부여하는 방법으로 본 발명에 따른 도장강판(1)이 완성된다.That is, the fragrance coating layer 6 includes a high molecular polyester resin, thereby providing a dual three-dimensional texture by using protrusions formed by polypropylene pigment particles and differences in thermosetting density of the paint. The coated steel sheet 1 is completed.
이와 같이, 하도도장층(5)과 방향도장층(6)으로 구성된 고분자 폴리에스테르 도막층은, 수요자의 사용 용도에 따른, 가공시 나타나는 가공부위의 도막균열(크랙)이나, 사용 중 발생되는 표면오염 방지 등의 제반 요구사항을 해결하기 위하여 도막의 연신율이 우수하고 내오염이 우수하게 하였다. As described above, the polymer polyester coating layer composed of the undercoat layer 5 and the aromatic coating layer 6 has a coating film crack (cracks) at the processing site that appears during processing or a surface generated during use according to the use purpose of the consumer. In order to solve various requirements such as pollution prevention, the elongation of the coating film was excellent and the pollution resistance was excellent.
또한, 여기서 방향도장층(6)은, 도막표면에 나타나는 질감을 나타내기 위해서는 10-30㎛의 폴리프로필렌계 왁스에 의해 질감을 부여되며, 향을 발생하는 물질을 마이크로 캡슐화한 방향입자(10)가 첨가되어 있음으로써, 제조된 본 발명에 따른 도장강판(1)의 표면에는 방향입자(10)가 방향도장층(6)의 표면에 부상되어 있게 되어 본 발명에 따른 도장강판(1)의 표면을 손이나 걸레 등으로 문지를 경우 방향입자(10) 내에 향을 발생하는 물질이 대기 중에 노출되면서 냄새가 확산되는 특성을 가지고 있다.In addition, the aromatic coating layer 6 is provided with a texture by polypropylene wax of 10-30㎛ in order to exhibit the texture appearing on the surface of the coating film, and the aromatic particles 10 which microencapsulates the substance generating the aroma. By the addition, the surface of the coated steel sheet 1 according to the present invention is allowed to float on the surface of the direction coating layer 6 on the surface of the coated steel sheet 1 according to the present invention. In the case of rubbing with a hand or a mop, the smell-producing substance is exposed to the atmosphere while the fragrance-producing substance 10 is exposed to the air.
여기서, 본 발명에 따른 도장강판(1)으로부터 발산되는 향은, 각종 허브향, 각종 꽃향, 각종 과일향, 각종 맛을 내는 조미료의 향,(예를 들어 커피향, 초컬릿향, 바닐라향), 각종 음식 향, 그 외 한약재 향, 페로몬 향, 등으로 다양할 수 있다.Here, the flavor emitted from the coated steel sheet 1 according to the present invention is a variety of herb flavors, various flower flavors, various fruit flavors, flavors of various flavors (for example, coffee flavor, chocolate flavor, vanilla flavor), Various food flavors, other herbal flavors, pheromone flavors, etc. can vary.
여기에서, 본 발명에 따른 도장강판(1)으로부터 발산되는 향의 종류에 대해 기재하였으나, 본 발명에 따른 도장강판(1)으로부터 발산될 수 있는 향은 상기에 기재된 향에 국한되는 것이 아니며, 사람이 인식할 수 있는 향이면 모두 본 발명에 따른 도장강판(1)에 적용가능하다. Here, although the kind of incense emitted from the coated steel sheet 1 according to the present invention has been described, the incense that may be emitted from the coated steel sheet 1 according to the present invention is not limited to the incense described above, and All of these recognizable incense is applicable to the coated steel sheet 1 according to the present invention.
한편, 전술한 실시예에서는 방향도장층(6)을 구성하는 상도도료에 폴리프로필렌계 왁스가 포함되었으나, 폴리프로필린계 왁스 대신에 폴리아마이드계 왁스를 포함할 수도 있다. Meanwhile, in the above-described embodiment, the polypropylene wax is included in the top coat constituting the fragrance coating layer 6, but polyamide wax may be included instead of the polypropylene wax.
이상 설명한 바와 같이, 본 발명에 따른 도장강판을 사용한 제품이 실내에 배치되었을 경우에는, 방향입자가 대기 중에 노출되면서 향이 실내에 확산되므로 실내에 불쾌한 냄새를 제거하며 또한 정서적으로 안정감을 느낄 수 있는 쾌적한 실내환경을 제공할 수 있다.
