캐스팅 필름 제조과정 중의 용액 또는 겔 상의 액상 수지는 캐스팅 필름 제막용 시트 표면에서 액상에서 점차 고상으로 변화하며, 이 과정에서 물질 간의 상대적인 인력의 크기는 비례적으로 유지된다.The liquid resin on the solution or gel in the casting film manufacturing process gradually changes from the liquid phase to the solid phase on the surface of the casting film forming sheet, and in this process, the magnitude of relative attraction between materials is maintained in proportion.
상기 인력의 크기는 시트의 표면에너지(surface energy)로 표현될 수 있으며, 상기 표면에너지는 캐스팅 과정 중의 필름상 물질인 액상 수지의 형태유지와 제조된 캐스팅 필름과 시트의 분리 용이성과 연관되어 있다.The size of the attraction force may be expressed as the surface energy of the sheet, which is related to the shape retention of the liquid resin, which is a film material, during the casting process, and the ease of separation of the cast film and the sheet.
시트 표면과 증류수와의 접촉각은 상기 표면에너지를 상대적으로 나타내는 지표라고 할 수 있는데, 본 발명의 캐스팅 필름 제막용 다층 시트는 시트 표면(11)에 증류수(12)를 적하(滴下)하였을 때, 시트 표면과 증류수의 접촉각(13)이 90~140°의 범위가 되도록 한다(도 1 참조).The contact angle between the surface of the sheet and distilled water can be said to be an index indicating the surface energy relatively. In the multilayer film for casting film forming of the present invention, when distilled

측정은 접촉각 측정기(contact angle meter, DSA100, KRUSS사 제조, 독일)를 이용하여, 온도 20±2 ℃, 상대습도 40±25 %의 조건하에서 증류수를 마이크로뷰렛으로 적하하여 접촉각을 측정하였다.
The measurement was carried out using a contact angle meter (DSA100, manufactured by KRUSS, Germany), and distilled water was dropped into the microburette under conditions of a temperature of 20 ± 2 ° C. and a relative humidity of 40 ± 25% to measure the contact angle.
상기 표 2의 결과, 실시예의 경우 접촉각이 122°, 138°, 93° 및 124°를 나타내어 본 발명에 따른 캐스팅 필름 제막용 다층 시트의 표면과 증류수와의 접촉각이 90~140°의 범위에 있음을 알 수 있다.As a result of Table 2, in the case of the embodiment, the contact angles are 122 °, 138 °, 93 ° and 124 °, and the contact angle between the surface of the multilayer sheet for casting film deposition according to the present invention and distilled water is in the range of 90 to 140 °. It can be seen.
반면에 이오노머가 첨가되지 않은 비교예 1의 경우 접촉각이 145°를 나타내었으며, 이오노머가 과도하게 첨가된 비교예 2의 경우 접촉각이 88°를 나타내었다.
On the other hand, in Comparative Example 1, in which the ionomer was not added, the contact angle was 145 °, and in Comparative Example 2 in which the ionomer was excessively added, the contact angle was 88 °.
<시험예 2> 캐스팅 필름의 품질 평가Test Example 2 Evaluation of Quality of Casting Film
상기 실시예 및 비교예에서 제조된 캐스팅 필름 제막용 다층 시트를 사용하여 캐스팅 필름을 제조하고, 상기 제조된 캐스팅 필름의 균일성과 캐스팅성을 측정하여 하기 표 3에 나타내었다.Casting films were prepared using the multilayer sheets for casting film forming prepared in Examples and Comparative Examples, and the uniformity and casting properties of the prepared casting films were measured and shown in Table 3 below.
용제형 폴리우레탄(polyurethane grade # UCE-COAT 7212, CYTEC 제조, 미국)을 건조챔버의 온도가 120 ℃로 운전되는 상기 knife coating laminator에 투입하여 필름 두께를 15 ㎛로 캐스팅하여 캐스팅 필름을 제조하였다.
Solvent-type polyurethane (polyurethane grade # UCE-COAT 7212, manufactured by CYTEC, USA) was put into the knife coating laminator in which the temperature of the drying chamber is operated at 120 ℃ cast a film thickness of 15 ㎛ to prepare a casting film.
균일성 측정은 상기 캐스팅 필름의 불특정 5개 위치를 선정하여 200㎜×200㎜ 크기로 샘플을 취한 후 중량기준 (최대값-최소값)/(최소값)×100 (%)을 구한 후 다음과 같이 판정하였다.The uniformity measurement was performed by selecting five unspecified positions of the casting film, taking a sample in a size of 200 mm × 200 mm, and then determining the weight basis (maximum value-minimum value) / (minimum value) × 100 (%) and determining as follows. It was.
○ (균일) : 5 % 이하○ (uniform): 5% or less
× (불량) : 5 % 초과
× (defective): more than 5%
캐스팅성 측정은 캐스팅 필름 제막용 다층 시트 위에 형성된 캐스팅 필름의 슬립, 접힘 또는 기타 불량 형태를 육안으로 관찰하고, 형성된 캐스팅 필름을 분리하였을 때의 용이성을 관찰하여, 다음과 같이 판정하였다The castability measurement was visually observed for slip, fold or other defects of the cast film formed on the multilayer sheet for casting film forming, and the ease of when the formed cast film was separated was determined as follows.
○ (양호) : '불량 없음' 그리고 '분리됨'○ (good): 'no defect' and 'separated'
× (불량) : '불량 개소 1개 이상' 또는 '필름의 변형이나 파손 없이 쉽게 분리되지 않음'
× (defect): '1 or more defective points' or 'not easily separated without deformation or damage of film'
상기 표 3에서 알 수 있듯이, 실시예의 캐스팅 필름의 경우 캐스팅 필름의 불량발생이 없고, 캐스팅 필름 제막용 다층 시트로부터 캐스팅 필름의 분리가 변형 및 파손 없이 용이하게 이루어졌다.As can be seen in Table 3, in the case of the casting film of the embodiment there is no failure of the casting film, the separation of the casting film from the multilayer sheet for casting film film formation was easily made without deformation and breakage.
반면에 이오노머가 혼합되지 않은 비교예 1의 경우 제조된 캐스팅 필름의 불량이 5 %를 초과하였으며, 이는 상기 실험예 1의 결과 시트 표면과 증류수의 접촉각이 145°를 나타내어 캐스팅 필름 제조과정 중 필름상 물질의 형태가 유지되지 못하여 필름의 성형불량이 발생한 것으로 판단된다.On the other hand, in the case of Comparative Example 1, in which the ionomer was not mixed, the defect of the manufactured casting film exceeded 5%, which indicates that the contact angle between the surface of the sheet and the distilled water was 145 °, resulting in the film phase during the manufacturing process of the casting film. The shape of the material could not be maintained, it is judged that the poor molding of the film.
또한, 이오노머가 과도하게 혼합된 비교예 2의 경우 제조된 캐스팅 필름을 다층 시트로부터 분리시 변형이나 파손이 발생하였는데, 이는 실험예 1에서 접촉각이 88°를 나타내어 제조된 캐스팅 필름이 다층 시트와 용이하게 분리되지 못한 원인으로 추측된다.
In addition, in the case of Comparative Example 2 in which the ionomer was excessively mixed, deformation or breakage occurred when the manufactured casting film was separated from the multilayer sheet, which shows that the contact angle was 88 ° in Experimental Example 1 It is presumed to be the cause that could not be separated.
이상에서 살펴본 바와, 본 발명의 캐스팅 필름 제막용 다층 시트는 시트 표면과 증류수와의 접촉각이 90~140° 범위가 되도록 함으로써, 캐스팅 공정 중 필름상 물질의 형태가 유지되어 캐스팅 필름의 결점이나 불균일성을 방지할 수 있으며, 제조된 캐스팅 필름이 다층 시트로부터 용이하게 분리된다.As described above, the multilayer sheet for casting film forming according to the present invention has a contact angle between the surface of the sheet and distilled water within a range of 90 to 140 °, thereby maintaining the form of a film-like material during the casting process, thereby improving defects and nonuniformity of the casting film. Can be prevented, and the cast film produced is easily separated from the multilayer sheet.
특히, 다양한 박막 형태나 패턴을 가지는 필름상 제품을 제조할 경우 균일한 품질의 캐스팅 필름을 얻을 수 있으며, 상기 캐스팅 필름을 이용하여 섬유, 인테리어 및 전자 등의 산업분야에 응용될 수 있는 다양한 형태의 캐스팅 필름의 개발 및 적용이 가능하다.In particular, when manufacturing a film-like product having a variety of thin film forms or patterns it is possible to obtain a casting film of a uniform quality, by using the casting film of various forms that can be applied to industries such as textile, interior and electronics Development and application of casting films is possible.
