Description
본 발명은 가전용 강판으로서 사용되는 표면처리강판 제조용 Mo계 혼합 조성물에 관한 것으로, 보다 구체적으로 내흑화성이 우수한 Mo계 혼합 조성물 및 이를 이용한 내흑화성과 전기전도성이 우수한 표면처리강판에 관한 것이다.
The present invention relates to a Mo-based mixed composition for producing a surface-treated steel sheet used as a steel sheet for home appliances, and more particularly, to a Mo-based mixed composition having excellent blackening resistance and a surface-treated steel sheet having excellent blackening resistance and electrical conductivity using the same.
내지문 수지 용액을 코팅한 아연도금강판은 사람 손에 의한 지문이 형성되지 않기 때문에, 가전용 강판으로서 오래전부터 사용되어 왔다. Galvanized steel sheet coated with anti-fingerprint resin solution has been used for a long time as a steel sheet for home appliances because fingerprints are not formed by human hands.
그러나, 이러한 아연도금강판을 가공하게 되면 소프트(soft)한 아연도금층이 높은 압력을 받으면서 다이(die)와의 마찰에 의해 표면이 검게 변하는 흑화현상이 나타나는 문제점이 제기되었다.
However, when the galvanized steel sheet is processed, the soft zinc plated layer is subjected to a high pressure, and a blackening phenomenon in which the surface becomes black due to friction with the die has been raised.
이러한 문제점을 개선하기 위한 방안으로서, 아연도금층 위에 먼저 반응형 인산염을 처리한 후, 그 위에 내지문 수지 용액을 코팅한 강판이 제안되었다 (특허문헌 1). As a solution for improving such a problem, a steel plate coated with a reactive phosphate on a zinc plated layer first, and then coated with an anti-fingerprint resin solution thereon has been proposed (Patent Document 1).
상기 반응형 인산염은 인산 외에 아연, 망간, 니켈과 같은 금속이온들이 함유되어 있으며, 반응성을 높여주기 위해 질산, 불산과 같은 인체에 유해한 물질들도 포함되어 있다. The reactive phosphate contains metal ions such as zinc, manganese and nickel in addition to phosphoric acid, and also contains substances harmful to the human body such as nitric acid and hydrofluoric acid to increase reactivity.
이러한 반응형 인산염은 결정성을 가지는 것은 물론, 부착량도 1~3g/m2 정도의 많은 양이 형성되는데 이는 일정 부착량에 도달할 때까지 인산염 피막 형성 반응이 멈추지 않기 때문이다. 이와 같이, 반응형 인산염 피막은 많은 부착량과 결정성을 가지고 있기 때문에 가공성은 우수하나, 표면백색도가 급격하게 떨어지는 단점이 있다. 또한, 반응형 인산염 피막은 부도체이기 때문에 이후 코팅되는 수지층으로 인한 전기전도도 하락에 더하여 거의 전기가 통하지 않는 피막이 형성되어 전도성을 요구하는 부위에는 사용하기 어려운 사용상의 제약을 받는다.
These reactive phosphates not only have crystallinity but also have a large amount of adhesion amount of 1 to 3 g / m 2 because the phosphate film formation reaction does not stop until a certain amount of adhesion is reached. As such, the reactive phosphate coating has excellent adhesion since it has a large amount of adhesion and crystallinity, but has a disadvantage in that the surface whiteness drops sharply. In addition, since the reactive phosphate film is a non-conductor, in addition to the decrease in electrical conductivity due to the resin layer to be coated thereafter, an almost non-conductive film is formed, which makes it difficult to use at sites requiring conductivity.
본 발명은 상술한 문제점을 해결하기 위한 것으로, 강판을 가공한 후에도 내흑화성 뿐만 아니라 전기전도성도 우수한 표면처리강판 및 이의 제조방법을 제공하고자 한다.
The present invention is to solve the above-described problems, to provide a surface-treated steel sheet excellent in electrical conductivity as well as blackening resistance even after processing the steel sheet and a method of manufacturing the same.
본 발명의 일 측면은, 아연도금강판의 도금층 위에 도포되는 Mo계 혼합 조성물에 있어서, 몰리브덴 화합물 1~10 중량%, 폴리에틸렌글리콜(polyethylene glycol) 1~10 중량% 및 보론 화합물 1~10 중량% 및 잔부 물로 조성되는 혼합 조성물이고, 상기 혼합 조성물은 내흑화성 개선 도막을 형성하는 것을 특징으로 하는 Mo계 혼합 조성물을 제공한다.
One aspect of the invention, in the Mo-based mixed composition applied on the plating layer of the galvanized steel sheet, 1 to 10% by weight of molybdenum compound, 1 to 10% by weight of polyethylene glycol and 1 to 10% by weight of boron compound and It is a mixed composition composed of the balance water, the mixed composition provides a Mo-based mixed composition, characterized in that to form a blackening resistance improving coating film.
본 발명의 다른 측면은, 아연도금강판; 상기 아연도금강판의 도금층 위에 몰리브덴 화합물 1~10 중량%, 폴리에틸렌글리콜(polyethylene glycol) 1~10 중량% 및 보론 화합물 1~10 중량% 및 잔부 물을 포함하는 Mo계 혼합 조성물로 형성된 내흑화성 개선 도막; 및 상기 도막 위에 내지문 수지 용액으로 형성된 수지 도막을 포함하는 내흑화성 및 전기전도성이 우수한 표면처리강판을 제공한다.
Another aspect of the invention, galvanized steel sheet; The blackening resistance-improving coating film formed of a Mo-based mixed composition comprising 1 to 10% by weight of molybdenum compound, 1 to 10% by weight of polyethylene glycol, 1 to 10% by weight of boron compound, and the balance on the plating layer of the galvanized steel sheet. ; And it provides a surface-treated steel sheet excellent in blackening resistance and electrical conductivity comprising a resin coating film formed of a anti-fingerprint resin solution on the coating film.
본 발명에서 제공하는 Mo계 혼합 조성물을 코팅하고, 그 위에 내지문 수지 용액을 처리한 아연도금강판은 상기 혼합 조성물에 의해 형성된 도막이 가지는 우수한 미끄럼성으로 인해, 가공 시 흑화현상이 나타나지 않으며, 더불어 형성되는 도막의 두께가 10~20nm의 극박이므로 우수한 전기전도성도 나타낸다. 또한, 기존 반응형 타입에 비해 용액의 손실량이 적으며, 도포형 형태이기 때문에 질산, 불산과 같은 인체에 유해한 물질을 배제할 수 있어 친환경적이다.
The galvanized steel sheet coated with the Mo-based mixed composition provided in the present invention and treated with the anti-fingerprint resin solution thereon, due to the excellent sliding property of the coating film formed by the mixed composition, does not appear blackening during processing and is formed. Since the thickness of the coating film used is 10-20 nm ultra-thin, it also shows the outstanding electrical conductivity. In addition, the amount of loss of the solution is less than that of the conventional reactive type, and since it is a coated type, it is possible to exclude harmful substances such as nitric acid and hydrofluoric acid, which is environmentally friendly.

The present inventors studied in depth to derive a surface-treated steel sheet having both excellent blackening and electrical conductivity, and then processed the steel sheet by pre-treatment with a Mo-based mixed composition, followed by treatment with a fingerprint resin solution to form a coating film. After confirming that it is possible to provide a surface-treated steel sheet having blackening resistance and excellent electrical conductivity was completed the present invention.
이하, 본 발명의 구현에 의한 표면처리강판 제조용 Mo계 혼합 조성물에 대하여 보다 상세하게 설명한다.
Hereinafter, the Mo-based mixed composition for manufacturing a surface-treated steel sheet according to an embodiment of the present invention will be described in more detail.
본 발명에 의한 표면처리강판 제조용 Mo계 혼합 조성물은 몰리브덴 화합물 1~10 중량%, 폴리에틸렌글리콜(polyethylene glycol) 1~10 중량% 및 보론 화합물 1~10 중량% 및 잔부 물로 조성될 수 있다.Mo-based mixed composition for producing a surface-treated steel sheet according to the present invention may be composed of 1 to 10% by weight of molybdenum compound, 1 to 10% by weight of polyethylene glycol and 1 to 10% by weight of boron compound and the balance.
물은 상술한 화합물 이외의 잔부로서 포함된다. 상기 물의 양은 포함되는 화합물의 함유량에 따라 조절되며, 용매로서 작용한다.
Water is contained as remainder other than the compound mentioned above. The amount of water is adjusted depending on the content of the compound included, and acts as a solvent.
이때, 몰리브덴 화합물은 전기전도성을 향상시키는 물질로서 본 발명에서는 1~10 중량%를 첨가하는 것이 바람직하다. 몰리브덴 화합물의 함유량이 1 중량% 미만일 경우에는 아연도금강판의 전도성 향상을 기대하기 어려우며, 반면 10 중량%를 초과할 경우에는 전도성 향상 효과가 포화되어 더 이상의 효과를 기대하기 어려울 뿐만 아니라 고가의 몰리브덴이 다량 첨가되므로 비경제적이다. 본 발명에서 사용될 수 있는 몰리브덴 화합물의 구체적인 종류는 한정되는 것은 아니나, 예컨대 몰리브덴산암모늄(ammonium molybdate), 인몰리브덴산나트륨, 몰리브덴산나트륨(sodium molybdate) 중에서 선택된 1종을 적용할 수 있다.At this time, the molybdenum compound is a substance for improving the electrical conductivity, it is preferable to add 1 to 10% by weight in the present invention. If the content of the molybdenum compound is less than 1% by weight, it is difficult to expect improved conductivity of the galvanized steel sheet, whereas if the content of the molybdenum compound exceeds 10% by weight, it is difficult to expect further effects due to saturation of the conductivity enhancement effect. It is uneconomical because a large amount is added. Specific types of molybdenum compounds that can be used in the present invention are not limited, but for example, one selected from ammonium molybdate, sodium phosphmolybdate, and sodium molybdate can be applied.
폴리에틸렌글리콜(polyethylene glycol)은 화합물들의 결합력을 강화시킴으로써 아연도금강판 상에 조성물을 도포할 시 도막의 형성을 용이하게 하며, 또한 아연도금강판의 가공 후 내흑화성을 향상시키는 역할을 한다. 본 발명에서는 이러한 폴리에틸렌글리콜을 1~10 중량%로 첨가하는 것이 바람직하다. 폴리에틸렌글리콜의 함유량이 1 중량% 미만일 경우에는 아연도금강판의 내흑화성 향상 효과를 기대하기 어려우며, 반면 10 중량%를 초과하여 첨가할 경우에는 코팅용액의 거품 발생량이 많아지고, 침전물이 형성되어 코팅용액의 안정성이 떨어지는 문제점이 있다.Polyethylene glycol facilitates the formation of a coating film when the composition is applied on a galvanized steel sheet by strengthening the bonding strength of the compounds, and also serves to improve the blackening resistance after processing of the galvanized steel sheet. In the present invention, it is preferable to add such polyethylene glycol at 1 to 10% by weight. If the content of polyethylene glycol is less than 1% by weight, it is difficult to expect the effect of improving the blackening resistance of the galvanized steel sheet, whereas when it is added more than 10% by weight, the amount of foaming of the coating solution is increased, and a precipitate is formed to form a coating solution. There is a problem that the stability of the fall.
보론 화합물은 pH 완충, 표면외관 개선 및 내흑화성 개선을 위해 첨가하며, 본 발명에서는 1~10 중량%의 보론 화합물을 첨가하는 것이 바람직하다. 보론 화합물의 함유량이 1 중량% 미만이면 가공 후 내흑화성이나 pH 완충 및 표면외관 개선 효과를 기대하기 어려우며, 반면 10 중량%를 초과할 경우에는 용액의 안정성이 떨어져 침전물을 형성하게 된다. 본 발명에서 사용될 수 있는 보론 화합물의 구체적인 종류는 한정되는 것은 아니나, 예컨대 붕산(boric acid), 붕사(sodium borate), 산화보론(B2O3), 유기보론 화합물(organoboron compound) 중에서 선택된 1종을 적용할 수 있다.
The boron compound is added to improve the pH buffer, surface appearance and blackening resistance, in the present invention, it is preferable to add 1 to 10% by weight of the boron compound. When the content of the boron compound is less than 1% by weight, it is difficult to expect the effect of blackening resistance, pH buffering and surface appearance improvement after processing, whereas when the content of the boron compound exceeds 10% by weight, the stability of the solution is reduced to form a precipitate. Specific types of boron compounds that can be used in the present invention is not limited, for example, boric acid (boric acid), borax (sodium borate), boron oxide (B 2 O 3 ), one selected from organoboron compound (organoboron compound) Can be applied.
이하, 본 발명의 구현에 의한 표면처리강판에 대하여 보다 상세하게 설명한다.
Hereinafter, the surface-treated steel sheet according to the embodiment of the present invention will be described in more detail.
본 발명의 일 구현예에 의한 표면처리강판은 아연도금강판의 아연도금층 위에 몰리브덴, 폴리에틸렌글리콜(PEG), 보론 화합물로 이루어진 Mo계 혼합 조성물을 도포하여 내흑화성 개선 도막이 형성된 것이다. The surface-treated steel sheet according to an embodiment of the present invention is to form a blackening resistance improvement coating coating a Mo-based mixed composition consisting of molybdenum, polyethylene glycol (PEG), boron compound on the zinc plated layer of the galvanized steel sheet.
이때, 본 발명이 적용되는 아연도금강판은 특별히 한정하지 않는 것으로서, 아연계 전기도금강판, 아연계 합금 전기도금강판, 용융아연도금강판, 합금화 용융아연도금강판 등을 포함한다.
At this time, the galvanized steel sheet to which the present invention is applied is not particularly limited, and includes a zinc-based electroplated steel sheet, a zinc-based alloy electroplated steel sheet, a hot dip galvanized steel sheet, an alloyed hot dip galvanized steel sheet, and the like.
이하, 본 발명에 따른 표면처리강판에 대해 상세히 설명한다.
Hereinafter, the surface-treated steel sheet according to the present invention will be described in detail.
본 발명에 따른 Mo계 혼합 조성물을 이용하여 아연도금강판 위에 내흑화성 개선 도막을 형성할 시, 상기 도막의 두께는 10~20nm로 형성시키는 것이 바람직하며, 이를 위해 50~200mg/m2의 도막 부착량으로 Mo계 혼합 조성물을 도포하는 것이 바람직하다. 도막 부착량이 50mg/m2 미만이면 내흑화성을 개선하기 어려우며, 반면 200mg/m2을 초과하게 되면 가공 후 전도성이 하락하는 문제가 발생한다.
When forming the blackening resistance improving coating film on the galvanized steel sheet using the Mo-based mixed composition according to the present invention, the thickness of the coating film is preferably formed in 10 ~ 20nm, for this purpose 50 ~ 200mg / m 2 coating film adhesion amount It is preferable to apply Mo-based mixed composition. If the coating film adhesion amount is less than 50mg / m 2 it is difficult to improve the blackening resistance, whereas if it exceeds 200mg / m 2 there is a problem that the conductivity decreases after processing.
본 발명의 일 구현예에 의한 표면처리강판의 내흑화성 개선 도막은 50~200mg/m2 부착량으로 형성되고 그 두께도 10~20nm로 매우 얇은 피막이므로 강판을 가공한 후에도 우수한 내흑화성을 갖도록 할 수 있다. 또한, 상기 혼합 조성물은 금속계 화합물로 이루어져 있기 때문에, 기존 반응형 인산염을 처리하여 형성한 피막에 비해 전기전도성을 향상시킬 수 있다. 더불어, 상기 혼합 조성물은 도포형 타입으로서 강판 위에 도막을 형성시키는 데에도 유리하다.
The blackening resistance improvement coating film of the surface-treated steel sheet according to an embodiment of the present invention is formed with a coating amount of 50 ~ 200mg / m 2 and the thickness is also very thin film of 10 ~ 20nm, so it can have excellent blackening resistance even after processing the steel sheet have. In addition, the mixed composition is made of a metal-based compound, it is possible to improve the electrical conductivity compared to the film formed by treating the existing reactive phosphate. In addition, the mixed composition is advantageous in forming a coating film on a steel sheet as an application type.
또한, 본 발명에 의한 표면처리강판은 아연도금강판의 아연도금층 위에 상술한 조건들을 만족하도록 내흑화성 개선 도막을 형성한 후, 상기 도막 위에 내지문 수지 용액을 도포하여 수지 도막이 형성된 것이다.
In addition, the surface-treated steel sheet according to the present invention is to form a blackening resistance-improving coating film to satisfy the above-described conditions on the zinc plated layer of the galvanized steel sheet, and then the anti-fingerprint resin solution is applied on the coating film to form a resin coating film.
상기 내지문 수지 용액은 강판 표면상에 지문 또는 스크래치가 형성되는 것을 방지하기 위한 목적으로 강판의 표면에 도포하는 수지 용액이다. The anti-fingerprint resin solution is a resin solution applied to the surface of the steel sheet for the purpose of preventing fingerprints or scratches from forming on the surface of the steel sheet.
본 발명에서는 통상의 내지문 수지 용액이라면 어떠한 것도 적합하게 사용할 수 있으며, 예컨대 우레탄계 수지, 아크릴계 수지, 에폭시계 수지 및 이들의 혼합 수지 중 1종 또는 2종 이상이 사용될 수 있다. 더불어, 상기 수지 이외에도 경화제나 첨가제 등이 추가적으로 첨가될 수 있다.
In the present invention, any conventional anti-fingerprint resin solution can be suitably used, and for example, one or two or more of a urethane resin, an acrylic resin, an epoxy resin, and a mixed resin thereof can be used. In addition, in addition to the resin, a curing agent or an additive may be additionally added.
상기 내지문 수지 용액으로 수지 도막을 형성할 시, 강판 가공시 외부 압력에 충분히 견딜 수 있을 정도의 피복층을 갖도록 형성되는 것이 좋으며, 따라서 그 두께가 0.5~1.5μm로 형성되도록 500~1500g/m2의 부착량을 도포하는 것이 바람직하다.
When the resin coating film is formed of the anti-fingerprint resin solution, it is preferable to have a coating layer that can sufficiently withstand the external pressure during steel sheet processing, so that the thickness is 500 to 1500 g / m 2 so as to form a thickness of 0.5 to 1.5 μm. It is preferable to apply the deposition amount of.
본 발명의 표면처리강판은 종래의 강판과 달리 반응형 인산염 처리를 행하지 않은 강판일 수 있다.
Unlike the conventional steel sheet, the surface-treated steel sheet of the present invention may be a steel sheet not subjected to reactive phosphate treatment.
이하, 본 발명의 구현에 의한 표면처리강판의 제조방법에 대하여 보다 상세하게 설명한다.
Hereinafter, a method of manufacturing a surface-treated steel sheet according to an embodiment of the present invention will be described in more detail.
본 발명의 표면처리강판 제조방법은 Mo계 혼합 조성물을 아연도금강판 위에 도포하는 단계; 혼합 조성물이 도포된 아연도금강판을 건조하는 단계; 그 위에 내지문 수지 용액을 도포하는 단계; 및 내지문 수지 용액이 도포된 아연도금강판을 건조하는 단계를 포함한다.
Method for producing a surface-treated steel sheet of the present invention comprises the steps of applying a Mo-based mixed composition on a galvanized steel sheet; Drying the coated galvanized steel sheet; Applying an anti-fingerprint resin solution thereon; And drying the galvanized steel sheet to which the anti-fingerprint resin solution is applied.
이하, 상세히 설명한다.
It will be described in detail below.
[Mo계 혼합 조성물에 의한 내흑화성 개선 도막 형성][Formation of blackening resistance improvement coating film by Mo-type mixed composition]
아연도금강판의 도금층 위에 몰리브덴 화합물, 폴리에틸렌글리콜 및 보론 화합물을 포함하는 Mo계 혼합 조성물을 도포한 후 건조하여 내흑화성 개선 도막을 형성한다.The Mo-based mixed composition including the molybdenum compound, polyethylene glycol and boron compound is applied on the plating layer of the galvanized steel sheet and dried to form a blackening resistance improving coating.
이때, 용액 도포는 롤코팅 방법 또는 분사, 침적 등의 방식을 이용할 수 있다. 용액 도포 방법으로서 롤코팅 방법을 이용할 경우 롤의 주속비와 니프(Nip)압을 조절함으로써 목표로 하는 부착량을 얻을 수 있으며, 반면 분사나 침적을 통해 용액을 도포할 경우에는 도포된 용액이 강판의 표면으로부터 흘러 내림을 방지하고, 부착량을 조절하기 위해 링거롤(Wringer roll)을 이용하여 도포량을 조절함이 필요하다.At this time, the solution coating may use a roll coating method or a method such as spraying, deposition. In the case of using the roll coating method as a solution coating method, the target adhesion amount can be obtained by adjusting the circumferential ratio of the roll and the nip pressure, while in the case of applying the solution by spraying or depositing, the applied solution is applied to the steel sheet. It is necessary to adjust the coating amount by using a Ringer roll in order to prevent falling down from the surface and to control the deposition amount.
용액 도포를 완료한 후, 강판을 건조할 시 건조효율면에서 강판의 최고온도를 나타내는 PMT(Peak Metal Temperature)로 60~150℃에서 건조하는 것이 바람직하다. 이로써 한정하는 것은 아니지만, 예컨대 건조방식이 열풍건조 방식인 경우에는 도포된 용액을 250~350℃에서 5~15초 동안 열풍처리하여 건조할 수 있다.
After the solution coating is completed, it is preferable to dry at 60 ~ 150 ℃ by PMT (Peak Metal Temperature) representing the highest temperature of the steel sheet in terms of drying efficiency when drying the steel sheet. Although not limited thereto, for example, when the drying method is a hot air drying method, the applied solution may be dried by hot air treatment at 250 to 350 ° C. for 5 to 15 seconds.
[수지 도막 형성][Resin coating film formation]
상기와 같이 아연도금강판의 도금층 위에 Mo계 혼합용액으로 도막을 형성한 후, 그 위에 내지문 수지 용액을 도포하여 수지 도막을 형성한 후 건조하여 목적하는 두께의 수지 도막을 형성한다.As described above, after forming a coating film with a Mo-based mixed solution on the plating layer of the galvanized steel sheet, the anti-fingerprint resin solution is applied thereon to form a resin coating film and then dried to form a resin coating film having a desired thickness.
이때, 내지문 수지 용액을 도포하는 방법과 도포 후 강판을 건조하는 방법은 기존의 내지문 강판을 제조할 시 적용하였던 어떠한 방식도 가능하다. At this time, the method of applying the anti-fingerprint resin solution and the method of drying the steel plate after the application may be any method applied when manufacturing the conventional anti-fingerprint steel sheet.
수지 용액을 도포하는 방법으로서, 예컨대 롤코팅 방법을 이용할 경우, 롤코팅 방법에 의한 내지문 수지 처리공정에 대해 간략히 설명하면 다음과 같다. 우선 믹싱(mixing) 탱크에서 원하는 수지 조성(주제, 경화제, 첨가제, 순수)을 순차적으로 투입하고, 이를 충분히 교반한 후 순환배관을 통해 코터팬(coater pan)까지 이송시키고, 코터팬에서 롤코터(roll coater)로 강판 위에 수지 용액을 도포하게 된다.As a method of apply | coating a resin solution, when the roll coating method is used, for example, the anti-fingerprint resin processing process by a roll coating method is briefly described as follows. First, the desired resin composition (subject, curing agent, additives, pure water) is added sequentially in the mixing tank, and after sufficiently stirring, it is transferred to the coater pan through the circulation pipe and the roll coater (from the coater pan). A roll coater is used to apply the resin solution onto the steel sheet.
내지문 수지 용액을 도포한 후, 강판을 건조할 시, PMT(Peak Metal Temperature)로 100~200℃에서 건조하는 것이 바람직하며, 이와 같이 강판을 건조시킴으로써 0.5~1.5μm의 두께를 갖는 수지 도막을 얻을 수 있다. 이때, 수지 도막의 두께가 0.5μm 미만으로 형성될 경우에는 내식성 확보가 불가능하고, 반면 1.5μm를 초과하게 되면 전도성이 급격히 저하되고, 건조시에도 문제가 발생한다.
After coating the anti-fingerprint resin solution, when drying the steel sheet, it is preferable to dry at 100-200 ° C. with PMT (Peak Metal Temperature), and by drying the steel sheet in this way, a resin coating film having a thickness of 0.5-1.5 μm is formed. You can get it. At this time, when the thickness of the resin coating film is formed to less than 0.5μm it is impossible to secure the corrosion resistance, while if it exceeds 1.5μm, the conductivity is sharply lowered, a problem occurs even when drying.

먼저, 본 발명에 의한 Mo계 혼합 조성물을 하기 표 1의 조성범위로 제조한 후, 이 용액을 알칼리 탈지한 0.7mm 두께의 전기아연도금강판(EG 강판)에 바코터(bar coater)#3으로 균일하게 도포한 후 340℃ 분위기의 열풍건조로에서 5초간 건조하여 내흑화성 개선 도막을 형성하였다. 건조시 강판의 온도(PMT)는 70℃였다.First, the Mo-based mixed composition according to the present invention was prepared in the composition range shown in Table 1 below, and then the solution was coated with a bar coater # 3 on a 0.7 mm-thick electrogalvanized steel sheet (EG steel sheet) alkali-degreased.

<비교예 1>≪ Comparative Example 1 &
알칼리 탈지한 0.7mm 두께의 전기아연도금강판(아연도금 부착량 20g/m2) 표면을 표면조정한 후 반응형 인산염 처리하여 반응형 인산염 피막 형성하였다. The surface of the alkali-degreased 0.7 mm-thick electrogalvanized steel sheet (zinc plating amount 20 g / m 2 ) was surface-controlled, and then reactive phosphate was formed to form a reactive phosphate film.
이때, 표면 조정은 입도 0.01~0.1μm인 Ti3(PO4)2를 함유하는 pH 7의 티탄 콜로이드 표면조정제를 2초간 처리함으로써 수행하였다. 또한, 반응형 인산염 처리는 표면 조정한 강판을 인산아연, 질산, 인산니켈 및 F 화합물의 에칭제를 포함하는 인산염 용액에 4.5초간 침지하였다. 이로써 얻어진 반응형 인산염 피막은 43%의 Zn, 41%의 PO4, 0.3%의 Ni, 0.2~0.3%의 Fe 및 0.1% 이하의 F를 포함하며, 부착량은 1200mg/m2 였다.At this time, the surface adjustment was carried out by treating the titanium colloid surface regulator of pH 7 containing Ti 3 (PO 4 ) 2 having a particle size of 0.01 ~ 0.1μm for 2 seconds. In addition, in the reactive phosphate treatment, the surface-adjusted steel sheet was immersed in a phosphate solution containing zinc phosphate, nitric acid, nickel phosphate, and an etchant of an F compound for 4.5 seconds. The reactive phosphate coating thus obtained contained 43% Zn, 41% PO 4 , 0.3% Ni, 0.2-0.3% Fe and 0.1% or less F, and the deposition amount was 1200 mg / m 2 .
반응형 인산염 피막을 형성한 후, 인산염 피막 상에 에틸렌 아크릴 수지에 5 중량%의 멜라민 수지 경화제 및 20 중량%의 실리카를 첨가한 내지문 수지 코팅 용액을 롤코팅 방법으로 도포한 다음, 강판온도를 180℃로 설정한 상태에서 소부하고, 수냉시켜 두께 1.3μm의 수지 도막을 갖는 강판을 제조하였다. 이때, 수지 도막의 부착량은 950mg/m2 였다.
After the reactive phosphate film was formed, an anti-fingerprint coating solution containing 5% by weight of melamine resin curing agent and 20% by weight of silica was added to the ethylene acrylic resin on the phosphate film by a roll coating method, and then the steel sheet temperature was applied. The steel plate was baked in the state set at 180 degreeC, water-cooled, and the resin coating film of 1.3 micrometers in thickness was manufactured. At this time, the adhesion amount of the resin coating film was 950 mg / m <2> .
<비교예 2>Comparative Example 2
알칼리 탈지한 0.7mm 두께의 전기아연도금강판(아연도금 부착량 20g/m2) 표면에 어떠한 피막도 형성시키지 않은 상태에서 상기 비교예 1에서와 동일한 내지문 수지 용액을 롤코팅 방법으로 도포한 후, 강판온도를 180℃로 설정한 상태에서 소부하고, 수냉시켜 두께 1.3μm의 수지 도막을 갖는 강판을 제조하였다. 이때, 수지 도막의 부착량은 1000mg/m2 였다.
After applying the same anti-fingerprint resin solution as in Comparative Example 1 in the state that no film was formed on the surface of the alkali-degreased 0.7 mm thick electrogalvanized steel sheet (zinc plating amount 20 g / m 2 ), The steel plate was baked in the state which set the steel plate temperature to 180 degreeC, it was water-cooled, and the steel plate which has a resin coating film of 1.3 micrometers in thickness was produced. At this time, the adhesion amount of the resin coating film was 1000 mg / m <2> .
상술한 방법들에 의해 제조된 강판은 편면 마찰계수 측정장치로 마찰계수를 측정한 후, 표면의 백색도를 측정하여 흑화되는 정도를 평가하였으며, 전기전도성 평가는 표면저항 측정기기를 이용하여 측정하였다. 이하, 측정방법 및 결과에 대해 상세히 설명한다.
The steel sheet manufactured by the above-described methods was measured by measuring the friction coefficient with a one-sided friction coefficient measuring device, and then evaluated the degree of blackening by measuring the whiteness of the surface, and the electrical conductivity evaluation was measured using the surface resistance measuring device. Hereinafter, the measuring method and the result will be described in detail.
<흑화성 평가법-백색도 측정><Blackness Evaluation Method-Whiteness Measurement>
강판을 가공할 시 강판 표면의 흑화 정도를 평가하기 위해 마찰계수 측정장치를 이용하였다. 시편을 14×300mm로 절단한 후 이를 마찰시험기에 장착하여 650kgf로 가압력을 가한 후, 1000mm/min의 속도로 장치의 다이를 200mm 잡아당겨 색차계로 시편 표면의 백색도를 측정하였다. 측정 결과는 하기 표 2 및 도 1에 나타내었다.Friction coefficient measuring apparatus was used to evaluate the degree of blackening of the steel sheet surface when the steel sheet was processed. After cutting the specimen into 14 × 300mm, it was mounted on a friction tester and pressed with 650kgf. Then, the die of the device was pulled 200mm at a speed of 1000mm / min and the whiteness of the surface of the specimen was measured by a color difference meter. The measurement results are shown in Table 2 and FIG. 1.
통상, 전기아연도금강판의 표면은 은백색을 띠고 있으며, 매우 미려하여 백색도를 측정하게 되면 약 90 정도를 나타내게 된다. 이러한 전기아연도금강판에 내지문 수지 용액을 코팅한 비교예 2의 강판을 마찰계수를 측정한 후 표면 백색도를 측정한 결과 76 정도를 보였으며, 이러한 결과는 아연도금층이 가공에 의해 흑화되어 그 위에 수지 도금이 형성되어 있다 하더라도 흑화현상이 그대로 전사되어 검게 나타나기 때문인 것으로 사료된다. In general, the surface of the galvanized steel sheet has a silver white color, and is very beautiful, and when the whiteness is measured, the surface of the galvanized steel sheet is about 90 degrees. After measuring the coefficient of friction of the steel sheet of Comparative Example 2 coated with the anti-fingerprint resin solution on the electro-galvanized steel sheet, the surface whiteness was about 76, and the result was that the galvanized layer was blackened by machining. Even if the resin plating is formed, it may be because blackening phenomenon is transferred to black color as it is.
그러나, 발명예 1 내지 3과 비교예 1의 경우에는 강판을 가공할 시 하지층(발명예의 경우에는 내흑화성 개선 도막, 비교예 1의 경우에는 반응형 인산염 피막)이 도금층을 보호하고 윤활작용을 하기 때문에, 백색도 측정 결과가 모두 84~86의 높은 값을 유지함을 확인할 수 있다. 다만, 비교예 1에 비해 발명예 1 내지 3의 경우가 가공하기 전 전기아연도금강판의 백색도 값과 유사한 값을 나타냄을 알 수 있다.
However, in the case of Inventive Examples 1 to 3 and Comparative Example 1, when the steel sheet is processed, the underlying layer (blackening resistance improving coating film in the case of the invention example, reactive phosphate coating film in the case of Comparative Example 1) protects the plating layer and prevents lubrication. Therefore, it can be confirmed that all the whiteness measurement results maintain the high value of 84-86. However, it can be seen that the case of Inventive Examples 1 to 3 compared to Comparative Example 1 shows a value similar to the whiteness value of the galvanized steel sheet before processing.
<전기전도성 측정><Electric conductivity measurement>
강판 표면의 전기전도도는 표면저항 측정장치(LORESTA-GP)를 이용하여 측정하였으며, 측정 결과는 하기 표 2 및 도 2에 나타내었다.Electrical conductivity of the surface of the steel sheet was measured using a surface resistance measuring device (LORESTA-GP), the measurement results are shown in Table 2 and FIG.
하기 표 2에 나타낸 바와 같이, 발명예 1 내지 3 및 비교예 2의 경우에는 0.04~0.05 mΩ의 표면저항 값을 나타내는 것으로 보아 전기전도성이 우수함을 알 수 있으나, 아연도금층 위에 반응형 인산염 피막과 수지 도막을 순차적으로 형성시킨 비교예 1의 경우에는 표면저항 값이 무한대로 측정되어 전기전도성이 없는 것으로 확인되었다.
As shown in Table 2, in the case of Inventive Examples 1 to 3 and Comparative Example 2, it can be seen that the electrical conductivity is excellent because it shows a surface resistance value of 0.04 to 0.05 mΩ, but the reactive phosphate film and the resin on the zinc plated layer In the case of Comparative Example 1 in which the coating film was formed sequentially, the surface resistance value was measured to infinity, and it was confirmed that there was no electrical conductivity.
