Abstract
본 고안은 인체에 해로운 크롬산을 전혀 사용하지 않고, 또한 심가공될 때 건성오일이나 타발유나 프레스유를 바르지 않고 가공가능토록 하기위해, 공지의 갈바륨강판에 고윤활성의 기능을 갖는 갈바륨강판으로 제조함에 있어, 갈바륨강판(1)의 표면에 우레탄계의 수용성 윤활수지를 코팅하여 윤활수지층(2)을 형성한 것을 특징으로 하는 무도유 가공용 갈바륨강판에 관한 것이다.The present invention does not use any chromic acid that is harmful to the human body, and is also made of galvalume steel sheet having a high lubricating function on a known galvalume steel sheet so that it can be processed without applying dry oil, punching oil or press oil when deep processing. The present invention relates to a galvalume steel sheet for non-oil processing, wherein a lubrication resin layer (2) is formed by coating a urethane-based water-soluble lubricating resin on the surface of the galvalume steel sheet (1).
Description
본 고안은 가공시 윤활유나 프레스유를 도포할 필요가 없는 무도유 가공용 갈바륨 강판에 관한 것이다.The present invention relates to a galvalume steel sheet for non-oil processing, which does not need to apply lubricant or press oil during processing.
일반적으로 알루미늄-아연 합금도금강판은 철강제품의 내구성 및 내식성을 향상시키기 위하여 냉간 압연강판에 알루미늄-아연 합금을 용융도금하여 만든 강판이다.In general, aluminum-zinc alloy plated steel sheet is a steel sheet made by hot-dip aluminum-zinc alloy on cold-rolled steel sheet to improve the durability and corrosion resistance of steel products.
최근 수요 증가를 보이고 있는 알루미늄-아연 합금도금강판은 그 수요 분야에 있어서도 건축자재 및 방음벽, 자동차, 가전제품 등의 산업기기의 도장강판으로 점차 확산되고 있다.Aluminum-zinc alloy-coated steel sheet, which is showing increasing demand in recent years, is gradually spreading to coated steel sheets of industrial materials such as construction materials, soundproof walls, automobiles, and home appliances.
이 알루미늄-아연 합금도금강판은 알루미늄의 함량에 따라 갈판(GALFAN)강판과, 갈바륨(GALVALUME)강판 두 종류가 있다. 갈판은 알루미늄이 4-10중량%, 반 이상의 아연 및 적은 양의 Mg등을 배합한 저알루미늄-아연 합금강판이고, 갈바륨은 알루미늄이 55중량%, 아연이 43.3중량%, 소량의 Si를 합금도금한 고알루미늄-아연 합금강판이다. 상기의 합금도금강판은, 일반적인 아연도금 강판에 비하여 알루미늄이 많을 수록 내식성이 2-6배로 매우 우수하고 내열성 및 열반사성도 우수하다.There are two kinds of aluminum-zinc alloy plated steel plates, depending on the content of aluminum, galvanized steel and galvalume steel. Galvanized steel is a low aluminum-zinc alloy steel sheet containing 4-10% by weight of aluminum, more than half of zinc, and a small amount of Mg. Galvalume is alloyed with 55% by weight of aluminum, 43.3% by weight of zinc, and a small amount of Si. It is a high aluminum-zinc alloy steel sheet. The alloy plated steel sheet is very excellent in corrosion resistance 2-6 times as much aluminum as compared to the general galvanized steel sheet, and also excellent in heat resistance and heat reflectivity.
기존의 갈바륨강판은 윤활성이 없어서, 심가공을 할 경우에는 윤활유를 도포하고 작업하는 것이 일반적이다. 그러므로 냉장고 등의 가전제품의 부품으로서 적용하기 위한 갈바륨강판의 가공을 할 경우, 프레스유나 윤활유를 도포하여 가공한 뒤, 다시 프레스유나 윤활유를 제거하기 위해 탈지제(주로 액체 프레온이나 알카린)를 사용하여 표면에 뭍은 기름류를 제거하고 건조시킨 뒤, 그대로 제품으로 사용하거나 또는 분체도장을 하여 사용한다.Conventional galvalume steel sheet is not lubricating, so when deep processing, it is common to apply and work with lubricating oil. Therefore, when processing galvalume steel sheet for application as parts of home appliances such as refrigerators, apply press oil or lubricating oil, and then use degreaser (mainly liquid freon or alkaline) to remove press oil or lubricating oil again. Remove oils on the surface, dry them, and use them as a product or powder coating.
그러나 상기한 종래의 갈바륨 강판은 프레스유나 윤활유를 사용함으로 인해 환경오염을 유발하게 되고, 또한 탈지제로 이용하는 알카린도 환경오염을 유발하지만 무엇보다도 액체 프레온을 탈지제로 사용하면 이 액체프레온이 증발하여 대기중에 발산되면 오존층을 파괴하는 주원인이 되므로 심각한 문제를 일으킨다. 따라서 타발유를 사용하지 않고 직접 가공가능한 강판이 요구되어 왔다.However, the above-described conventional galvalume steel sheet causes environmental pollution by using press oil or lubricating oil.Alkaline used as a degreasing agent also causes environmental pollution, but above all, when liquid freon is used as a degreasing agent, the liquid freon evaporates to the atmosphere. If released in the air, the main cause of destroying the ozone layer causes serious problems. Therefore, there has been a need for a steel sheet that can be processed directly without using punching oil.
따라서, 본 고안은 상기한 종래의 요구에 부응하여 가공을 위해 도포하는 윤활유, 프레스유 및 알카린, 액체프레온 등의 탈지제등을 직접사용하지 않고 가공이 가능한 무도유 윤활성 갈바륨강판을 고안하게 되었다.Accordingly, the present invention has been made in accordance with the above-mentioned conventional requirements to devise an oil-free lubricating galvalume steel sheet which can be processed without directly using a lubricant, a press oil and a degreasing agent such as alkaline, liquid freon, etc. to be applied for processing.
이하, 본 고안을 더욱 구체적으로 상술한다.Hereinafter, the present invention will be described in more detail.
제1도는 본 고안에 따른 무도유 갈바륨강판을 나타내는 단면구성도.1 is a cross-sectional view showing an oil-free galvalume steel sheet according to the present invention.
제2도의 (a), (b)는 본 고안에 따른 갈바륨강판과 종래의 갈바륨강판의 가공성을 시험해본 사진물이다.(A) and (b) of FIG. 2 are photographs that test the workability of the galvalume steel sheet according to the present invention and the conventional galvalume steel sheet.
* 도면의 주요부분에 대한 부호의 설명* Explanation of symbols for main parts of the drawings
1 : 갈바륨강판 2 : 윤활수지층1: galvalume steel sheet 2: lubricating resin layer
본 고안에서는, 99.995%이상의 고순도 알루미늄과 99.995%이상의 고순도 아연을 사용하여 이들의 조성비를 각각 55%, 43.4%로 만들고, 여기에 실리콘을 1.6% 첨가한 용융도금강판, 즉 갈바륨강판(1) 위에, 우레탄 계열의 윤활수지를 코팅하였다.In the present invention, using 99.995% high purity aluminum and 99.995% high purity zinc to make their composition ratio 55% and 43.4%, respectively, on the hot-dip galvanized steel sheet, i.e. galvalume steel sheet 1, to which silicon is added 1.6%. , Urethane-based lubricant resin was coated.
사용되는 윤활수지는 수용성수지로서, 가공시 연신을 갖는 것이 아니고 소지강판의 연신과 더불어 미세한 조각으로 되어야 한다. 일반적인 수지처럼 밀려서 뭉개지거나 뭉처지면, 금형의 발열의 원인이 되거나 또는 가공되어야할 제품이 파열되거나 하는 경우가 발생한다.The lubricating resin used is a water soluble resin, which does not have elongation in processing and should be made into fine pieces together with elongation of the base steel sheet. When pushed or crushed like a general resin, a mold may generate heat or a product to be processed may rupture.
상기한 우레탄 계열의 윤활수지를 코팅한 고윤활성을 갖는 본 고안에 따른 무도유 가공용 갈바륨강판을 제조하는 방법은, 일반 상업용의 냉간강판(SAE 1006 및 1008) 및 lF 강판 위에 침지식 용융도금을 하면서 부착량을 편면 평당 미터당 10-25미크론으로 조절한 다음 다른 후처리, 예로서, 크롬산처리를 하지 않고 바로 윤활성을 나타내는 수용성수지를 롤코우터에서 1-3㎛미크론 정도로 코팅하여, 제1도에서와 같은 윤활수지층(2)이 형성되도록 코팅도막을 형성한다.The method of manufacturing a galvanium steel sheet for non-oil processing according to the present invention having a high lubricating activity coated with the above-described urethane-based lubricating resin, while immersion hot dip plating on a commercial steel cold plate (SAE 1006 and 1008) and lF steel sheet The adhesion amount is adjusted to 10-25 microns per meter per side and then coated with a water-soluble resin that shows lubricity immediately without other post-treatment, such as chromic acid treatment, on a roll coater on the order of 1-3 μm micron, as shown in FIG. A coating film is formed so that the lubricant resin layer 2 is formed.
즉, 이에 사용되는 윤활성분을 갖는 수지는 대한페인트잉크(주)에서 개발한 W650 이라는 제품을 사용하여 만들며, 처리방법은 상기의 W650을 얇은 막으로 롤코팅을 하고, 드라이 오븐에서 강판의 온도를 섭씨 120도-180도로 가열하여 수냉에 의해 냉각 및 건조시키면 완성된다.That is, the resin having a lubricating component used for this is made by using a product called W650 developed by Daehan Paint Ink Co., Ltd., and the treatment method is a roll coating of W650 with a thin film, and the temperature of the steel sheet in a dry oven. It is completed by heating to 120 degrees Celsius-180 degrees Celsius and cooling and drying by water cooling.
완성된 갈바륨강판의 내식성을 시험한 결과, 비가공 상태에서 염수분무를 했을 경우, 500시간 이상의 내백청성을 갖는다. 한편, 코팅처리한 강판 표면의 마찰계수는 0.035-0.07사이의 범위로 하는 것이 바람직하다. 상기의 표면마찰계수 범위를 벗어나면, 표면의 마찰력이 커서 가공시에 열이 심하게 발생되므로 오일레스 플레이트 제품으로 가치가 없다.As a result of testing the corrosion resistance of the finished galvalume steel sheet, when the salt spray is applied in the unprocessed state, it has a whiteness of 500 hours or more. On the other hand, the coefficient of friction of the coated steel sheet surface is preferably in the range of 0.035-0.07. If the surface friction coefficient is out of the range, the frictional force of the surface is so great that heat is generated during processing, so it is not worth it as an oilless plate product.
한편, 내식성을 얻는 방법은, 기존의 전기아연도금강판은 고내식성을 얻기 위하여 고내식성 크롬산을 면적 미터당 20-120 미리그람을 코팅하여야 하지만, 본 고안에서 사용하는 갈바륨 강판은 그 자체가 고내식성을 가지므로, 환경이나 인체에 해로운 크롬산을 처리할 필요가 없다.On the other hand, the method of obtaining corrosion resistance, the existing galvanized steel sheet should be coated with high corrosion resistance chromic acid 20-120 milligrams per square meter in order to obtain high corrosion resistance, but the galvalume steel sheet used in the present invention itself has a high corrosion resistance Therefore, there is no need to treat chromic acid that is harmful to the environment or the human body.
제2도에 첨부된 사진은 가공성 시험을 비교해 본 것으로, 본 고안에 따른 윤활 갈바륨강판을 사용한 예(a)와, 종래의 일반 갈바륨강판을 사용한 예(b)를 나타낸 것이다. 비교 사진물에서 보듯이, 본 고안에 따른 갈바륨 강판은 크랙이 발생하지 않아 종래 보다 가공성이 뛰어남을 확인할 수 있다.The photograph attached to FIG. 2 compares the workability test, and shows an example (a) using a lubricated galvalume steel sheet according to the present invention, and an example (b) using a conventional general galvalume steel sheet. As shown in the comparison picture, the galvalume steel sheet according to the present invention can be confirmed that there is no cracking processability than the conventional.
상기한 본 고안에 따른 무도유 가공용 갈바륨강판은, 상술한 바와 같은 탁월한 윤활성과 가공성이 뛰어나며 가공후, 염수분무 시험에 의한 내식성 촉친시험에서도 우수한 결과를 나타내고 있다.The galvalume steel sheet for non-oil processing according to the present invention described above has excellent lubricity and workability as described above, and shows excellent results in corrosion resistance stimulation test by salt spray test after processing.
또한 본 고안에 의하면 강판의 가공시, 프레스유나 윤활유를 사용할 필요가 없으며, 또한 이를 제거하기 위한 탈지제를 사용하지 않음으로써, 환경오염을 방지할 수 있고 또한 가공 공정도 크게 간편해지는 지대한 효과가 있다.In addition, according to the present invention, it is not necessary to use press oil or lubricating oil when processing the steel sheet, and also by using no degreasing agent to remove it, it is possible to prevent environmental pollution and greatly simplify the processing process.
