Abstract
본 발명은 수용성 폴리이미드 복합물로 표면 코팅된 기능성 플라스틱 필름에 관한 것이다. 본 발명의 기능성 플라스틱 필름은 유독성 유기용제, 계면활성제, 반응성 경화제 등을 첨가하지 않아 친환경적일 뿐만 아니라, 열 성형성, 내수성, 내유성, 내구성, 내열성, 내한성, 내블록킹성 등이 우수하므로, 코팅층의 박막화·경량화가 필요한 전기, 전자, 건축, 제약, 식품, 생활용품 포장 및 적층 소재 분야 등 관련 분야에 유용하게 사용될 수 있다.The present invention relates to a functional plastic film surface coated with a water-soluble polyimide composite. The functional plastic film of the present invention is not only environmentally friendly as it does not add toxic organic solvents, surfactants, reactive hardeners, etc., but also has excellent thermoformability, water resistance, oil resistance, durability, heat resistance, cold resistance, blocking resistance, etc., so the coating layer It can be usefully used in related fields such as electricity, electronics, architecture, pharmaceuticals, food, household goods packaging, and laminated material fields that require thinning and lightweighting.
Description
본 발명은 수용성 폴리이미드를 이용한 플라스틱 박막 필름에 관한 것이다. The present invention relates to a plastic thin film using water-soluble polyimide.
일반적인 플라스틱 박막 필름들은 물질의 화학적 구조로 인하여 물리·화학적 특성들이 각각 다르게 나타나며, 그로 인해 다양한 용도로 사용처가 구분된다.General plastic thin films exhibit different physical and chemical properties due to the chemical structure of the material, and as a result, they are used for various purposes.
종래의 플라스틱 박막 필름들은 단일 재질로 물성을 향상시키는데 한계가 있어 압출 라미네팅 또는 드라이 라미네이팅 합지 방식으로 기능성 소재를 다층(Multi layer)으로 구성하여 물성을 보완함으로써 다양한 산업 분야에 적용 중이다. 특히, 현재 업계의 개발 방향이 친환경성을 중요시하게 되면서, 다층으로 구성된 라미네이팅 소재들을 경량화, 박막화하거나 산업폐기물을 감소시킬 수 있는 소재를 발굴 중이며 고기능화, 생산성 향상, 가격 경쟁력 확보 등에 주력하는 추세이다. Conventional plastic thin films have limitations in improving physical properties using a single material, so they are applied to various industrial fields by supplementing physical properties by composing functional materials into multilayers using extrusion laminating or dry laminating methods. In particular, as the current development direction of the industry places importance on eco-friendliness, materials that can make multi-layered laminating materials lighter or thinner or reduce industrial waste are being discovered, and there is a trend to focus on making them highly functional, improving productivity, and securing price competitiveness.

In addition, the conventional coating layer was cured at high temperatures by adding a curing agent to polyurethane, acrylic, or epoxy resin, or the physical properties were improved by adding inorganic ceramics to silicone or fluoropolymer. However, there were many shortcomings in satisfying all physical properties such as thermoformability, water resistance, oil resistance, durability, heat resistance, cold resistance, blocking resistance, and flame retardancy.

In this case, there is a disadvantage that dispersibility is reduced.
상술한 탄소 나노튜브는 필름에 가해진 열을 발산시켜 필름의 변형을 감소시키고 난연성을 증가시키는 역할을 한다.The carbon nanotubes described above serve to reduce deformation of the film and increase flame retardancy by dissipating heat applied to the film.

This refers to a low-speed production coating method that applies thin film coating liquid uniformly and precisely by minimizing the contact area between the surface and the film.
