Description
본 발명은 다양한 재료의 요철면 위에 다양한 문양을 전사할 수 있는 외장재용 전사필름의 제조방법에 관한 것이다. 좀 더 구체적으로, 본 발명은 철, 알루미늄, 플라스틱, 세라믹, 고무 및 유리 등의 다양한 요철면에 다양한 문양을 전사할 수 있으며, 내후성이 개선된 외장재용 전사필름의 제조방법에 관한 것이다.The present invention relates to a method of manufacturing a transfer film for an exterior material which can transfer various patterns on an uneven surface of various materials. More specifically, the present invention can transfer a variety of patterns on various irregularities such as iron, aluminum, plastic, ceramics, rubber and glass, and relates to a method for manufacturing a transfer film for an exterior material having improved weather resistance.
종래의 전사필름에는 시이트상에 박리층, 보호층, 인쇄층 및 접착층이 차례로 적층된 전사필름(참조: 일본 특허공개 (평)9-58196호)과, 시이트에 박리성 도료의 이형층, 인쇄층, 은폐층 및 접착제층이 차례로 적층하여 형성한 전사필름(참조: 일본 특허공개 (평)7-47798호); 및, 수지층, 이형층, 보호프라이마층 및 인쇄층이 차례로 적층된 전사필름(참조: 대한민국 특허공고 제 96-2721호) 등이 알려져 있다. 따라서, 종래의 이러한 전사필름은 베이스층, 이형층, 인쇄층 및 접착제층 등으로 이루어져 있으므로, 수전사시 박리공정이 복잡하며, 열전사시에는 요철면위에 의도하는 문양의 전사가 쉽게 이루어지지 않는 문제점이 있었다. 더구나, 종래의 전사필름은 도막밀착성, 연필경도, 도막두께 및 내알칼리성 등 전사필름으로서의 물성이 열악한 단점을 포함하고 있었다.Conventional transfer films include transfer films (see Japanese Patent Application Laid-Open No. 9-58196), in which a release layer, a protective layer, a print layer, and an adhesive layer are sequentially stacked on a sheet, and a release layer of a peelable paint and a print on the sheet. A transfer film formed by sequentially laminating a layer, a concealment layer, and an adhesive layer (see Japanese Patent Application Laid-Open No. 7-47798); And transfer films (refer to Korean Patent Publication No. 96-2721) in which a resin layer, a release layer, a protective primer layer, and a printing layer are sequentially stacked are known. Therefore, the conventional transfer film is composed of a base layer, a release layer, a printing layer and an adhesive layer, so that the peeling process is complicated during water transfer, and the transfer of the intended pattern on the uneven surface during heat transfer is not easy. There was this. In addition, the conventional transfer film had a disadvantage of poor physical properties as a transfer film, such as coating film adhesion, pencil hardness, coating film thickness and alkali resistance.
한편, 대한민국 특허출원 제 98-11085호에는 상술한 문제점을 보완한 주필름층, 인쇄층 및 유연성코팅층으로 이루어진 전사필름이 개시되어 있으나, 전기 전사필름의 경우에는 내후성이 전혀 고려되지 않아, 장시간 햇볕(자외선), 비, 바람 등에 노출되어야만 하는 외장재로서는 산업적으로 응용되는데 한계가 있었다.On the other hand, Korean Patent Application No. 98-11085 discloses a transfer film composed of a main film layer, a printing layer, and a flexible coating layer that solves the above-mentioned problems. Exterior materials that must be exposed to (ultraviolet rays), rain, wind, etc. had limitations in industrial applications.
따라서, 박리공정이 간단하고, 문양의 전사가 용이하며, 동시에 내후성이 강하여, 외장재로서 사용이 가능한 전사필름을 개발하여야 할 필요성이 끊임없이 대두되었다.Therefore, the necessity of developing a transfer film which can be used as an exterior material has been continuously raised because of a simple peeling process, easy transfer of patterns, and strong weather resistance.
이에, 본 발명자들은 다양한 문양을 어떠한 요철면에라도 간단하게 전사할 수 있고, 나아가 내후성이 강하여 외장재로 널리 사용할 수 있는 외장재용 전사필름을 개발하기 위하여 예의 연구 노력한 결과, 물, 폴리비닐알콜, 전분 및 펄프를 주성분으로 하고, 설탕, 비누, 아교, 라텍스, 실리콘오일 및 수용성 대전방지제를 함유하는 펄프층에 전기 각 성분에서 펄프를 제외한 성분을 함유하는 주필름층을 부착하고, 전기 주필름층에 세라믹 안료와 불소수지를 배합하여 제조한 인쇄잉크로 인쇄하면, 종래기술의 단점을 해결할 수 있는 우수한 물성을 가지는 전사필름이 제조됨을 확인하고, 본 발명을 완성하게 되었다.Accordingly, the inventors of the present invention, as a result of earnest research efforts to develop a transfer film for exterior materials that can easily transfer various patterns to any uneven surface, and can also be widely used as exterior materials due to its strong weather resistance, water, polyvinyl alcohol, starch and A main film layer containing components other than pulp in each of the above components is attached to a pulp layer containing pulp as a main component, sugar, soap, glue, latex, silicone oil, and water-soluble antistatic agent, and ceramic When printing with a printing ink prepared by mixing a pigment and a fluorine resin, it was confirmed that a transfer film having excellent physical properties that can solve the disadvantages of the prior art, and completed the present invention.
결국, 본 발명의 주된 목적은 다양한 문양을 다양한 요철면 위에 효율적으로 전사할 수 있는 외장재용 전사필름의 제조방법을 제공하는 것이다.After all, the main object of the present invention is to provide a method for manufacturing a transfer film for exterior materials that can efficiently transfer a variety of patterns on a variety of irregularities.
