초록

표면을 개질시켜 극성기를 도입한 다음 열융착시키는 방법으로 접착제를 사용하지 않고도 폴리에틸렌 필름과 알루미늄 판을 직접 접합시킬 수 있는지를 살펴보았다. 폴리에틸렌 필름은 산소 및 아크릴산 플라즈마로 처리하여 극성기를 도입하였으며, 알루미늄 판은 끓는 물로 처리하거나 diaminocyclohexane 플라즈마로 처리하여 극성기를 도입하였다. 폴리에틸렌 필름의 표면만을 개질시킬 경우에도 상당히 높은 접착력을 얻을 수 있었으며, 알루미늄 판의 표면까지 개질시킬 경우에는 접착시험시 폴리에틸렌 필름이 끊어질 정도로 높은 접착력을 얻을 수 있었다. 특히, 아크릴산플라즈마로 처리한 폴리에틸렌 필름과 diaminocyclohexane 플라즈마로 처리한 알루미늄 판을 접합시킬 경우에는 필름 표면의 카르복실기와 판 표면의 아민기가 반응하여 아마이드 그룹을 형성하는 화학적 결합에 대한 가능성도 보여주었다.

Direct thermal lamination of polyethylene film on aluminum plate without using adhesive was tried by modifying their surfaces to have polar groups. Polyethylene film was modified by treating with oxygen or acrylic acid plasma. Aluminum plate was modified by treating with boiling water or diaminocyclohexane plasma. Fairly high adhesion strength was obtained even in the case when only the polyethylene film was modified, and adhesion strength was so high that film was broken during the adhesion test if both the film and the aluminum plate were modified. Even chemical bonding seemed to be possible when the film treated with acrylic acid was laminated on the plate treated with diaminocyclohexane plasma by forming amide linkage through the reaction between COOH groups on the film surface and NH2 groups on the plate surface.
