Description

폴리에스테르 적층 금속판체의 제조방법Manufacturing method of polyester laminated metal plate

본 발명은 금속판체 적층용 폴리에스테르 필름 및 이를 이용한 폴리에스테르 적층 금속판체의 제조 방법에 관한 것이다. 더 구체적으로는 이축배향 폴리에스테르와 비결정성 선형 폴리에스테르로 구성된 복합 폴리에스테르필름의 비결정성 폴리에스테르쪽면에 안료가 첨가된 잉크로 인쇄를 행하여 적층용 필름을 제조한 후 연속도장라인에서 복합 폴리에스테르필름의 인쇄면쪽을 크로메이트 및 도장 처리된 고온의 금속판체에 압착롤을 이용하여 적층시켜 표면성 및 의장성이 우수한 폴리에스테르 필름 적층 금속판체를 제조하는 방법에 관한 것이다.The present invention relates to a polyester film for metal plate laminate and a method for producing a polyester laminated metal plate body using the same. More specifically, the composite polyester film composed of biaxially oriented polyester and amorphous linear polyester is printed with ink in which a pigment is added to the amorphous polyester side to prepare a laminated film, and then the composite polyester in a continuous coating line. The printing surface side of a film is laminated | stacked on the high temperature metal plate body subjected to chromate and painting process using a press roll, and the method of manufacturing the polyester film laminated metal plate body excellent in surface property and designability.

금속 스트립과 같은 금속판체에 합성수지 필름을 적층시키는 것은 공지의 기술이다. 폴리에스테르 필름은 금속판체에 우수한 특성을 부여하기 위해 금속판체에 적층하는 데 빈번히 이용되고 있다. 대개 결정성이면서 배향구조를 갖는 폴리에스테르 필름을 금속판체에 적층하는데 그 이유는 결정성이면서 배향성을 갖는 폴리에스테르 필름이 우수한 화학적, 열적, 물리적 및 기계적 특성을 동시에 갖고 있기 때문이다. 그러나 이러한 결정성이면서 쌍축 배향된 폴리에스테르 필름을 금속판체에 적층시키기란 쉽지 않음이 알려져 있다.It is a known technique to laminate a synthetic resin film on a metal plate such as a metal strip. Polyester films are frequently used to laminate on metal plates to impart excellent properties to the metal plates. Usually, a crystalline and oriented polyester film is laminated on a metal plate because the crystalline and oriented polyester film has excellent chemical, thermal, physical and mechanical properties simultaneously. However, it is known that such crystalline and biaxially oriented polyester film is not easy to be laminated on a metal plate body.

일반적으로 금속판체에 배향성 수지 필름을 연속적으로 적층하는 2가지 방법이 잘 알려져 있다. 제 1 방법은 접착제가 도포된 금속판체를 사용하는 방법이다. 즉, 처음에는 용매속에 열경화수지가 주로 분산되어 있는 접착제가 금속판체의 표면에 도포된다. 다음에는 접착제를 경화시킨 후에 합성수지 필름을 금속판체에 적층시키고 수분 동안 큰 용량의 오븐에서 가열처리 한다. 그후 합성수지 필름이 적층된 금속판체가 냉각된다. 제 2 방법은 접착제가 도포된 합성수지 필름을 사용하는 방법이다. 이 경우에는 합성수지 필름이 금속판체에 적층되고 제 1 방법에서와 같이 큰 용량의 오븐내에서 장시간 가열된다. 그러나, 이 방법들은 접착제를 경화시키고 합성수지 필름을 적층한 후 가열하는 데 긴 시간을 필요로 한다는 문제점이 있다. 또한 어떤 경우에는 접착제로 사용하는 열경화 수지의 성형성이 좋지 않기 때문에 적층된 합성수지 필름이 가공시에 금속판체의 표면으로부터 벗겨지기도 한다. 특히 의장성을 부여하기 위해 인쇄를 행한 배향성 필름을 적층할 경우 배향성 수지 필름과 인쇄층간의 접착력이 약하여 금속판체로 부터 합성수지 필름이 쉽게 떨어지는 문제점이 있다. 최근 이와 같은 문제점 없이 단순열접착에 의해 폴리에스테르필름을 금속판체에 적층하는 방법이 개발되었다.(한특개10-1998-019424) 그러나, 한특개 10-1998-019424는 이축배향 폴리에스테르와 비결정성 선형 폴리에스테르로 구성된 복합 폴리에스테르필름의 비결정성 폴리에스테르쪽면에 안료가 첨가된 폴리에스테르수지를 기본으로 한 잉크로 인쇄를 행하여 적층용 필름을 제조한 후 이를 연속도장라인에서 크로메이트 및 도장 처리된 고온의 금속판체에 압착롤을 이용, 적층하여 표면성 및 의장성이 우수한 폴리에스테르 필름 적층 금속판체를 제조하는 것을 특징으로 하고 있으나 도장된 금속판체의 우수한 접착력을 위해 폴리에스테르 필름 제조에 사용한 잉크가 전체 고형분중에 안료가 15% 미만으로 첨가되어 실제 적용시에 표현할 수 있는 색상에 한계가 있으며, 또한 인쇄용 잉크 및 복합폴리에스테르의 비결정성 폴리에스테르쪽면과 우수한 밀착력을 나타내는 접착성 도료를 사용하여야만 한다는 문제점이 있다.Generally, two methods of continuously laminating an oriented resin film on a metal plate are well known. The first method is a method of using a metal plate body coated with an adhesive. That is, initially, an adhesive on which the thermosetting resin is mainly dispersed in a solvent is applied to the surface of the metal plate body. Next, after curing the adhesive, the synthetic resin film is laminated on a metal plate and heat treated in a large oven for several minutes. Thereafter, the metal plate body on which the synthetic resin film is laminated is cooled. The second method is to use a synthetic resin film coated with an adhesive. In this case, the synthetic resin film is laminated on the metal plate body and heated for a long time in a large capacity oven as in the first method. However, these methods have a problem in that it takes a long time to heat the adhesive after curing the adhesive and laminating the resin film. Moreover, in some cases, since the moldability of the thermosetting resin used as an adhesive agent is not good, a laminated synthetic resin film may peel from the surface of a metal plate body at the time of processing. In particular, when laminating an oriented film printed in order to give designability, there is a problem that the adhesive film between the oriented resin film and the printing layer is weak and the synthetic resin film easily falls from the metal plate body. Recently, a method of laminating a polyester film on a metal plate by simple thermal bonding has been developed. (Korean Patent Application No. 10-1998-019424) However, Korean Patent Application No. 10-1998-019424 is a biaxially oriented polyester and an amorphous material. The composite polyester film composed of linear polyester was printed with ink based on polyester resin with pigments on the side of amorphous polyester to prepare a laminated film, which was then chromated and painted in a continuous coating line. It is characterized by manufacturing a polyester film laminated metal plate with excellent surface properties and design by laminating by using a pressing roll on a metal plate of the sheet, but the ink used in the manufacture of the polyester film is excellent for the excellent adhesion of the coated metal plate. Less than 15% of the pigment is added to the solids to create a color that can be expressed in practical applications. There is a limitation, and there is also a problem in that an adhesive paint exhibiting excellent adhesion with the amorphous polyester side of the printing ink and the composite polyester has to be used.

본 발명은 이와 같은 종래의 문제점을 해결하기 위한 것으로 비교적 저렴한 가격으로 모든 색상의 표면이 가능하고 표면성 및 의장성이 매우 우수할 뿐만 아니라 2차 가공시에 광택저하, 미세균열 발생 및 필름의 박리가 전혀 없어 우수한 표면성 및 의장성이 요구되는 전기 부품, 수납장용재, 가구 및 가정용품재, 내장건재로서 사용할 수 있는 폴리에스테르 적층 금속판체 제조에 이용할 수 있는 금속판체 적층용 폴리에스테르 필름 및 이를 이용한 폴리에스테르 필름 적층금속판체를 연속도장라인에서 제조하는 방법을 제공하는 것이다.The present invention is to solve such a conventional problem, it is possible to the surface of all colors at a relatively low price and very excellent surface and design, as well as gloss reduction, fine cracks and peeling of the film during the secondary processing Polyester film for laminating a metal plate that can be used to manufacture a polyester laminated metal plate that can be used as an electric component, a cabinet material, a furniture and a household material, and an interior building material which requires excellent surface properties and design. It is to provide a method for producing a polyester film laminated metal plate in a continuous coating line.

이와 같은 목적을 달성하기 위하여 본 발명에서는 이축배향 폴리에스테르와 비결정성 선형 폴리에스테르로 구성된 복합 폴리에스테르필름의 비결정성 폴리에스테르쪽면에 안료가 첨가된 잉크로 인쇄를 행하여 적층용 필름을 제조한 후 이를 연속도장라인에서 크로메이트 및 도장 처리된 고온의 금속판체에 압착롤을 이용, 적층하여 표면성 및 의장성이 우수한 폴리에스테르 필름 적층 금속판체를 제조하는 것을 특징으로 한다.In order to achieve the above object, in the present invention, a pigment is added to an amorphous polyester side of a composite polyester film composed of a biaxially oriented polyester and an amorphous linear polyester, and then printed with ink to prepare a laminating film. It is characterized by producing a polyester film laminated metal plate body having excellent surface properties and designability by laminating by using a pressing roll on a high temperature metal plate body which has been chromated and painted in a continuous coating line.

이하 본 발명을 자세히 설명한다.Hereinafter, the present invention will be described in detail.

본 발명에서 사용한 폴리에스테르 필름은 융점이 150℃ 초과 250℃ 미만이며 실제로 비결정성 선형 폴리에스테르인 내부층과 융점이 250℃를 초과하고 30% 이상의 결정성을 갖는 쌍축배향된 선형 폴리에스테르의 외부층으로 구성된 복합 폴리에스테르 필름으로 공압출에 의해 제조되는 것이 바람직하다. 접착층으로서의 역할을 수행하는 비결정성 선형 폴리에스테르인 내부층의 융점은 200℃ 부근인 것이 바람직하며 내부층의 두께는 전체 필름 두께의 20-30% 범위인 것이 바람직하다. 복합 폴리에스테르 필름의 전체 두께는 15-100um 이어야 하고, 바람직하기로는 15-50um 이나 그러한 범위에 한정되는 것은 아니다. 두께가 15um 이하가 되면 제조 및 물성상에 문제가 발생하며 두께가 100um 이상이 되면 경제적으로 부적당하다. 폴리에스테르 필름은 내스크래치성등을 향상시킬 목적으로 쌍축배향 선형 폴리에스테르인 외부층의 표면에 하드코팅을 수행 할 수도 있다.The polyester film used in the present invention has an inner layer whose melting point is higher than 150 DEG C and lower than 250 DEG C and is actually an amorphous linear polyester, and the outer side of the biaxially oriented linear polyester having a melting point exceeding 250 DEG C and having a crystallinity of 30% or more. It is preferably produced by coextrusion with a composite polyester film composed of layers. It is preferable that the melting point of the inner layer which is an amorphous linear polyester serving as an adhesive layer is around 200 ° C and the thickness of the inner layer is in the range of 20-30% of the total film thickness. The total thickness of the composite polyester film should be 15-100 um, preferably 15-50 um, but is not limited to such a range. If the thickness is less than 15um, problems occur in manufacturing and physical properties. If the thickness is more than 100um, it is economically inadequate. The polyester film may be hard coated on the surface of the outer layer which is a biaxially oriented linear polyester for the purpose of improving scratch resistance.

본 발명의 중요한 특징은 금속판체에 도장된 도료와 복합 폴리에스테르 필름의 내부층인 비결정성 선형 폴리에스테르와의 접착성이 우수할 뿐만 아니라 첨가할 수 있는 안료의 한계가 없어서 다양한 색상의 표현이 가능하며 또한 단순열첩착에 의해 도료가 도장된 금속판체와 우수한 접착력을 나타내는 잉크의 사용이다. 본 발명에서는 목적 달성을 위해 여러 종류의 잉크를 검토한 결과, 염화비닐(vinyl chloride) 85%이상, 비닐아세테이트(vinyl acetate) 3%이상, 비닐알코올(vinyl alcohol) 5%이상 및 기타 첨가제가 첨가된 수평균분자량이 20,000 이상인 수지에 안료가 50% 미만으로 첨가된 잉크가 이러한 물성을 모두 만족시킴을 알 수 있었다. 본 잉크를 사용하여 이축배향 폴리에스테르와 비결정성 선형 폴리에스테르로 구성된 복합 폴리에스테르필름의 비결정성 폴리에스테르쪽면에 인쇄를 행하여 색상에 제한 없이 인쇄가 가능하고 또한 다양한 도료가 도장된 금속판체에 단순 열접착만으로 적층이 가능한 금속판체 적층용 폴리에스테르 필름을 얻게 되었으며 이를 이용하여 폴리에스테르 필름 적층 금속판체의 제조가 가능하게 되었다. 안료가 첨가된 잉크만을 사용하여 인쇄를 행한 금속판체 적층용 폴리에스테르 필름이 도장된 금속판체와 밀착력이 낮을 경우에는 원하는 모양을 인쇄한 후에 다시 안료가 첨가되지 않은 수지만으로 구성된 투명잉크를 사용하여 전체 인쇄를 행할 수도 있다.An important feature of the present invention is not only excellent adhesion between the coating on the metal plate and the amorphous linear polyester, which is an inner layer of the composite polyester film, but also a variety of colors can be expressed because there is no limit to the pigment that can be added. In addition, it is the use of an ink showing excellent adhesion with a metal plate body coated with paint by simple thermal adhesion. In the present invention, as a result of examining various types of inks to achieve the object, at least 85% of vinyl chloride, at least 3% of vinyl acetate, at least 5% of vinyl alcohol, and other additives are added. It was found that the ink with less than 50% of the pigment added to the resin having a number average molecular weight of 20,000 or more satisfied all of these properties. This ink is used to print on the amorphous polyester side of a composite polyester film composed of biaxially oriented polyester and amorphous linear polyester, which enables printing without limitation on color and simple heat on a metal plate coated with various paints. A polyester film for laminating a metal plate body which can be laminated only by adhesion has been obtained, and the polyester film laminated metal plate body can be manufactured using the same. When the polyester film for laminating the metal plate printed using only the ink to which the pigment is added is low in adhesion strength to the coated metal plate, the transparent ink composed of only the resin which has no pigment added after printing the desired shape is used. Printing can also be performed.

본 발명에서 사용되는 금속판체는 표면처리가 되거나 또는 되지 않은 강판 또는 알루미늄판이다. 금속판체와 도료와의 밀착성 향상을 위해 금속판체 상에 먼저 크로메이트 처리를 행하는 것이 좋으며 또한 방청성을 더욱 향상시키기 위해서 크로메이트 처리 후에 프라이머 처리를 하는 것도 좋다. 따라서 한쪽면에 인쇄된 폴리에스테르 필름이 금속판체위에 직접 적층되는 것은 아니고 금속판체상에 도장된 도료위에 적층되는 것이므로 사용 가능한 금속판체에는 제한은 없다.The metal plate body used in the present invention is a steel sheet or an aluminum plate with or without surface treatment. In order to improve the adhesion between the metal plate and the paint, it is preferable to first chromate treatment on the metal plate body, and to further improve the rust resistance, primer treatment may be performed after the chromate treatment. Therefore, since the polyester film printed on one side is not directly laminated on the metal plate body, but is laminated on the paint coated on the metal plate body, there is no limitation on the usable metal plate body.

본 발명에서 폴리에스테르 필름 적층에 요구되는 금속판체의 가열은 별도의 공정을 통해서 행하지 않고 금속판체의 표면에 도장된 도료를 경화시키기 위한 가열을 이용한다. 금속판체의 가열온도는 200-250℃ 이어야 하고, 바람직하게는 210-230℃ 인 것이 좋다. 금속판체의 온도가 200℃ 미만이면 복합 폴리에스테르 필름 내부층의 용융이 불충분하여 접착력이 불량하며 250℃ 이상이 되면 복합 폴리에스테르 필름의 외부층의 결정배향성이 저하되어 내식성, 가공성등이 저하된다는 문제점이 있다.The heating of the metal plate body required for the polyester film lamination in the present invention uses heating for curing the coating material coated on the surface of the metal plate body without performing through a separate process. The heating temperature of the metal plate should be 200-250 ° C, preferably 210-230 ° C. If the temperature of the metal plate is less than 200 ° C., the melting of the inner layer of the composite polyester film is insufficient, resulting in poor adhesion. If the temperature of the metal plate is 250 ° C. or higher, the crystal orientation of the outer layer of the composite polyester film is lowered, which lowers the corrosion resistance and workability. There is this.

본 발명을 제조 공정에 따라서 설명하면 다음과 같다.When explaining the present invention according to the manufacturing process as follows.

제 1 도의 연속도장라인의 금속판체 공급장치에 코일 형태의 금속판체를 장입한 후 금속판체의 표면에 존재하는 불순물을 제거하기 위해서 전처리를 행한다. 전처리가 된 금속판체에 크로메이트 처리 및 건조 과정을 행한 후 도료를 통상의 롤코팅방법으로 도장한다. 도장 된 도료의 건조를 위해 고온으로 가열된 오븐으로 금속판체를 통과시켜서 금속판체를 가열하여 도료를 경화시킴과 동시에 크로메이트와 도료가 도장 처리 된 고온의 금속판체에 비결정성 폴리에스테르쪽면에 염화비닐 85%이상, 비닐아세테이트 3%이상, 비닐알코올 5%이상 및 기타 첨가제가 첨가된 수평균분자량 20,000 이상의 수지에 안료가 전체 고형분중 50% 미만 첨가된 잉크를 사용하여 인쇄되어 제조된 폴리에스테르 필름을 압착롤로 압착하여 금속판체에 폴리에스테르 필름을 적층 시킨다. 적층후 냉각을 행한 다음 금속판체감김장치에 감음으로써 코일 형태의 표면성 및 의장성이 매우 우수한 폴리에스테르 필름 적층 금속판체가 저렴한 가격으로 제조되게 된다.After the coil-shaped metal plate body is charged into the metal plate body supply device of the continuous coating line of FIG. 1, pretreatment is performed to remove impurities present on the surface of the metal plate body. After the pretreated metal plate is subjected to a chromate treatment and a drying process, the paint is coated by a conventional roll coating method. In order to dry the painted material, the metal plate is heated in an oven heated to a high temperature to heat the metal plate to cure the paint, and at the same time, a high temperature metal plate coated with chromate and paint on the amorphous polyester side of vinyl chloride 85 A polyester film prepared by printing using a ink containing less than 50% of the total solids in a resin having a number average molecular weight of 20,000 or more, containing at least%, at least 3% of vinyl acetate, at least 5% of vinyl alcohol, and other additives It is crimped | bonded with a roll and the polyester film is laminated | stacked on a metal plate body.
