Description
본 발명은 실리콘 증착강판의 미려한 색상을 보존하여 칼라강판으로 활용하기 위해 광택이 양호한 강판에 실리콘을 박도금하고 투명수지를 도포한 투명수지도포 실리콘 증착강판의 제조방법에 관한 것이다.The present invention relates to a method of manufacturing a transparent resin coated silicon deposited steel sheet in which silicon is plated and coated with a transparent resin in order to preserve the beautiful color of the silicon deposited steel sheet and utilize it as a color steel sheet.
강판은 강도가 우수하고 가공이 용이하여 가전제품 및 건자재용으로 많이 사용되고 있다. 그러나, 강판은 쉽게 부식이 된다는 취약점을 지니고 있어 이를 보완코자 강판 표면에 아연이나 알루미늄을 도금하여 내식성을 향상시키고 있다. 이와 같이 강판에 도장처리를 하여 강판의 내식성을 향상시킴과 아울러 도료가 가지는 다양한 색상을 이용하여 장식의 효과를 높이고 있다.Steel sheet is excellent in strength and easy to process, and is widely used for home appliances and construction materials. However, the steel sheet has a weakness that it is easily corroded to improve the corrosion resistance by plating zinc or aluminum on the surface of the steel sheet to compensate for this. In this way, the coating is applied to the steel sheet to improve the corrosion resistance of the steel sheet and to enhance the effect of decoration by using various colors of the paint.
강판에 색상을 표현하는 방법으로는 여러 가지 방법이 개발되어 있는데, 도료 자체가 가지는 색상을 이용하는 방법, 강판에 산화티타늄, 산화실리콘, 산화알루미늄 등의 산화물 등을 증착하여 빛의 간섭색을 이용하는 건식도금방법 등이 있다. 도료를 이용할 때는 도료의 불투명성으로 인하여 색상의 분위기가 전반적으로 어두워 보이며, 산화물을 증착시킬때는 산화물이 증발열원에 의해 화합물이 분해되어 진공챔버내의 진공도를 변화시킴으로 인하여 제조공정이 매우 까다로워 진다는 문제가 따른다.Various methods have been developed to express colors on steel sheets, and the method of using the color of the paint itself, and dry plating using light interference color by depositing oxides such as titanium oxide, silicon oxide, and aluminum oxide on the steel sheet. Method and the like. When using paint, the atmosphere of color appears to be dark due to the opacity of paint, and when depositing oxide, the process is very difficult because the oxide is decomposed by the evaporation heat source and changes the degree of vacuum in the vacuum chamber. Follow.
본 발명은 실리콘을 진공증착방식으로 강판에 도금시킬 때, 실리콘의 증발형태가 안정하여 제조가 용이하고 도금층은 실리콘-실리콘 산화물 혼합형태의 투명막으로 존재하게 되어 실리콘 도금층의 빛이 간섭색 효과로 인하여 다양한 색상을 표현하는데 용이할 뿐아니라, 도금층의 두께가 얇아 소지기판의 색상을 그대로 드러냄으로 광택을 가진 소지기판을 사용할 경우 밝은 색조를 얻을 수 잇다. 또한 본 발명에서는 도금층의 내스크레취(내scratch)성 및 내지문성을 확보하기 위해 투명한 수지를 실리콘 도금층에 도포하였다. 투명수지의 도포로 인하여 실리콘 도금층의 빛에 의한 간섭색 효과가 사라지지 않고 밝은 색조가 그대로 보존되었으며, 강판의 내식성을 향상시키는 효과도 있다.According to the present invention, when silicon is plated on a steel sheet by vacuum deposition, the evaporation form of silicon is stable and the production is easy. Not only is it easy to express various colors, but the thickness of the plating layer is thin so that the color of the small substrate is exposed. In the present invention, in order to secure scratch resistance and fingerprint resistance of the plating layer, a transparent resin was applied to the silicon plating layer. The application of the transparent resin did not disappear the interference color effect of the light of the silicon plating layer, the bright color tone was preserved as it is, and also has the effect of improving the corrosion resistance of the steel sheet.
본 발명의 제조공정을 상세히 설명하면 다음과 같다.Hereinafter, the manufacturing process of the present invention will be described in detail.
실리콘 증착도금에 사용된 소지강판은 제관용에 사용되는 전기주석 도금강판의 소재인 블랙플레이트(Black Plate)이다. 블랙플레이트 강판을 소지강판으로 사용하는 것은 블랙플레이트 강판 표면의 광택이 양호하여 실리콘 도금층의 밝은 색상을 표현하기가 용이했기 때문이다. 이 소지기판을 아세톤 및 알콜 용액에서 초음파 세척한 후, 진공챔버내에 장입하고 증발물질인 실리콘을 수냉식 수리 도가니에 채운 후 진공배기 시키고 전자빔을 이용하여 실리콘을 진공증착시킨다. 이때 강판의 예열 온도는 150∼300℃가 되게 한다. 같은 도금부착량에서도 예열온도에 따라 색상이 다르게 나타나기도 한다. 이는 실리콘 도금층이 기판 온도에 따라 실리콘-산소와 같이 조성비가 달라지고 결국 도금층 빛의 굴절율을 다르게 하기 때문이라 보인다.The base steel sheet used for the silicon deposition plating is a black plate (Black Plate), which is a material of the electro-tin plated steel sheet used for the pipe making. The use of the black plate steel sheet as the base steel sheet is because the gloss of the surface of the black plate steel sheet is good and it is easy to express the bright color of the silicon plating layer. The substrate is ultrasonically cleaned in acetone and alcohol solution, charged in a vacuum chamber, filled with evaporated silicon in a water-cooled repair crucible, evacuated and vacuum-deposited silicon using an electron beam. At this time, the preheating temperature of the steel sheet is to be 150 ~ 300 ℃. Even in the same coating weight, the color may appear different depending on the preheating temperature. This is because the silicon plating layer has a composition ratio that is different from that of silicon-oxygen depending on the substrate temperature, and thus the refractive index of the plating layer is different.
상기와 같이 제조된 실리콘 증착강판 위에 투명수지를 도포한다. 본 발명에서 사용된 투명 수지는 시판되고 있는 제품인 아크릴 알키드 수지 1702(Acrylic Modified Alkyd resin 1702) 및 아크릴 알키드 수지 410(Acrylic Modified Alkyd resin 410) 두가지이다. 본 발명의 중점 사항은 투명수지와 실리콘과의 밀착성 및 실리콘 박도금층의 빛에 의한 간섭색 효과에의 영향 등을 알기 위함이었으므로, 이 두가지 특성 외의 다른 특성에는 비중을 두지 않았다. 이 수지를 바-코터(bar coater)로 도포한 후 상온에서 30분간 자연건조시켰다. 이때 수지층의 두께는 약 20μm가 되도록 하였다.The transparent resin is coated on the silicon deposited steel sheet prepared as described above. Two transparent resins used in the present invention are acrylic modified alkyd resin 1702 and acrylic modified alkyd resin 410 which are commercially available products. The main focus of the present invention was to understand the adhesion between the transparent resin and silicon and the effect of the interference color effect caused by light of the silicon thin plated layer, and therefore, no emphasis was placed on other properties other than these two properties. The resin was applied with a bar coater and then naturally dried at room temperature for 30 minutes. At this time, the thickness of the resin layer was set to about 20 μm.

상기와 같이 제조된 시편을 다음과 같은 방법으로 그 특성평가를 실시하였다.The specimen prepared as described above was evaluated for its properties in the following manner.
1) 밀착성 시험 : 발명제품과 비교제품의 밀착성을 비교평가하여 위해 다음과 같이 두가지 방법을 병행하여 평가하였다.1) Adhesion test: In order to evaluate the adhesion between the invention and the comparative product, the following two methods were evaluated in parallel.
가) 충격시험(1,000g 추를 50cm에서 낙하)A) Impact test (drop 1,000g weight from 50cm)
나) 강판에 십자형 홈을 낸 후, 스카치 테이프를 밀착시킨 후 떼어내는 밀착성 시험B) Adhesion test in which a cross-shaped groove is made in the steel sheet, and then the Scotch tape is adhered to and peeled off.
2) 색차계 측정2) colorimeter measurement
수지로 인한 실리콘 도금층의 색상 변화정도를 확인하기 위해 색차례(Color differance Meter)사용하여 색상을 측정하였다. 색상은 L*, a*, b*값으로 나타낼 수 있는데, L* 값이 클수록 밝은 색조를 나타내며, 각각의 값은 a*: 빨간색, - a*: 녹색, b*:노란색, - b*: 파란색을 나타낸다. 값의 절대값이 클수록 기본 색상에 근접한다.Color was measured using a color differance meter to determine the degree of color change of the silicon plating layer due to the resin. Colors can be represented by L * , a * , b * values, with larger L * values representing lighter hues, with each value a * : red,-a * : green, b * : yellow,-b * : It is blue. The larger the absolute value of the value, the closer to the base color.
표 1에서 실시예 1-8에서 보여주듯이 실리콘 도금층은 실리콘 도금층 두께 및 수지층 두께와 관계없이 투명 아크릴 알키드 수지와의 밀착성이 우수하였다. 이는 기존 도장강판증 고가공성을 가지는 하이플리머 도마 밀착성과 동등 사이의 밀착성 가지고 있음을 보여주고 이다.As shown in Example 1-8 in Table 1, the silicon plating layer was excellent in adhesion with the transparent acrylic alkyd resin regardless of the silicon plating layer thickness and the resin layer thickness. This shows that it has the adhesiveness between the equivalent of the high-plymer cutting board having high processability of the existing coating steel sheet.
표 2에서 실시예 1-8은 비교예 5-8에 비해서 백색도가 전체적으로 3∼6 정도의 변화를 보였으나, 그 변화의 양이 작고 육안으로 관찰할 때도 색상의 변화가 적음을 확인할 수 있었다. 따라서 실리콘 증착강판에 투명수지를 도포함으로써 실리콘 증착강판이 가지는 밝은 색조를 그대로 유지 할 수가 있다.In Table 2, Example 1-8 showed a change in whiteness of about 3 to 6 as compared with Comparative Example 5-8, but the amount of change was small and the change in color was small even when visually observed. Therefore, by applying transparent resin on the silicon deposited steel sheet, it is possible to maintain the bright color tone of the silicon deposited steel sheet as it is.
색상의 변화에 있어서도 그 변화가 2∼7로 작았고, 오히려 기본 색상을 더 선명하게 한 결과도 얻을 수 있었다.In the change of color, the change was small (2-7), and the result of sharpening the basic color was also obtained.
이상의 특성평가를 통해서 광택을 가진 강판에 실리콘을 증착하여 투명수지를 도포한 것은 기존의 도장강판 대비 동등이상의 우수한 밀착성을 가지며, 진공증착 실리콘 도금층의 색상을 거의 동일한 수준으로 유지시키고 추가 내지문성의 특성도 가지므로 밝은 색조를 띤 도장강판으로 사용이 가능하다.As a result of the above characteristics evaluation, silicon deposited on glossy steel sheet and transparent resin coated had better adhesiveness than equivalent to conventional coated steel sheet, and kept the color of vacuum-deposited silicon plating layer at almost the same level and added additional fingerprint characteristics. It can also be used as a painted steel plate with bright hue.
