본 발명은 평판 유리의 안쪽 내면에 직접 부착되어 외부에서 안쪽 내면의 다양한 무늬와 색상을 감상할 수 있고, 유리의 내면에 필름이 위치하여 표면이 유리로 마감되므로 내마모성, 내용제성, 내약품성, 내스크래치성이 우수한 유리용 융착필름과 그 제조방법 및 그필름이 융착된 유리에 관한 것이다. 또한, 유리에 하도층을 형성할 필요가 없어 제조공정이 간소하고, 유리와의 접착력 및 층간 접착력이 우수하여 유리가 충격에 의해 파손되더라도 파편이 분산되지 않고 수분에 노출되더라도 인쇄층이 박리되지 않으므로 반영구적 제품의 제조가 가능한 유리용 융착 필름과 그 제조방법 및 그 필름이 융착된 유리에 관한 것이다.      The present invention is directly attached to the inner surface of the flat glass can be seen from a variety of patterns and colors of the inner surface from the outside, the film is located on the inner surface of the glass surface is finished with a glass wear resistance, solvent resistance, chemical resistance, resistance The present invention relates to a glass fusion film having excellent scratch resistance, a method of manufacturing the same, and a glass in which the film is fused. In addition, since there is no need to form an undercoat layer on the glass, the manufacturing process is simple, and the adhesion between the glass and the interlayer adhesion is excellent, so that even if the glass is broken by impact, the fragments are not dispersed and the printed layer does not peel off even when exposed to moisture. The present invention relates to a fusion film for glass capable of producing a semi-permanent product, a manufacturing method thereof, and a glass fused with the film.

유리의 표면에 무늬를 형성하는 방법으로 종래에는 스프레이 전사법 또는 실크스크린 인쇄법이 사용되었다. 그러나, 스프레이 전사법은 분사라는 방법의 한계로 인해 다양한 디자인의 구현이 어려웠을 뿐만 아니라, 분사된 물질이 대기중으로 확산되어 환경오염의 원인이 되었다. 실크 스크린 인쇄법은 동일한 디자인을 동일한 색상으로 반복 인쇄할 수 없어 동일한 컬러무늬가 인쇄된 유리를 대량으로 생산할 수 없다는 문제점을 가지고 있었다.      As a method of forming a pattern on the surface of glass, the spray transfer method or the silkscreen printing method was conventionally used. However, the spray transfer method was difficult to implement various designs due to the limitation of the spray method, and the sprayed material was diffused into the atmosphere, causing environmental pollution. The silk screen printing method has a problem that it is not possible to repeatedly print the same design with the same color, and thus cannot produce a large amount of glass printed with the same color pattern.

이러한 종래의 문제점을 해결하기 위하여 제안된 것이 소정의 무늬가 형성된 전사필름을 이용한 방법인데, 이 방법에 의하면 전사단계 이전에 접착제를 유리 표면에 도포하고 건조시키는 단계 및 전사된 무늬층을 보호하기 위하여 전사면의 상면에 보호층을 코팅하는 단계등이 포함되어 전체 공정이 다소 복잡하고, 전사된 무늬층을 보호하기 위하여 도포된 코팅의 두께가 얇고 경도가 약하면 스크래치와 같은 표면 손상이 쉽게 발생하는 단점이 있다.      In order to solve such a conventional problem, a method using a transfer film having a predetermined pattern is proposed. According to this method, an adhesive is applied to a glass surface and dried before the transfer step and to protect the transferred pattern layer. The overall process is somewhat complicated because it includes the step of coating the protective layer on the upper surface of the transfer surface, and if the thickness of the applied coating is thin and the hardness is weak to protect the transferred pattern layer, the surface damage such as scratch easily occurs. There is this.

또한, 유리는 기본적으로 내염성, 내스크래치성, 내마모성등이 우수하고, 쉽게 오염되지 않을 뿐만 아니라 청소가 용이하다는 장점을 가지고 있으나, 충격에 의해 깨질 염려가 있고, 재단할 때 물을 부으면서 재단하면 인쇄층이 파괴되거나 분리되는 현상이 많이 생긴다. 이런 문제로 가전제품이나 가구의 외부 마감재로 유리가 광범위하게 이용되지 못하고 있었다.In addition, glass has the advantages of excellent flame resistance, scratch resistance, abrasion resistance, etc., and is not easily contaminated and easy to clean, but it may be broken by impact, and when cut while pouring water when cutting, it is printed. Many of the layers are broken or separated. Because of this problem, glass was not widely used as exterior finishing material for home appliances or furniture.

상기의 문제점을 해결하고자, 본 발명에서는 유리에 다양한 무늬와 색상의 표현이 가능하고, 표면이 유리로 마감되어 내마모성, 내약품성 및 내스크래치성이 우수할 뿐만 아니라, 유리에 하도층을 형성할 필요가 없어 제조공정이 간소화되고, 유리와의 접착력 및 층간 접착력이 우수하여 유리가 파손되더라도 파편이 분산되지 않고 수분에 노출되더라도 인쇄층이 박리되지 않아 반영구적인 제품의 제조가 가능한 유리용 융착 필름과 그 제조방법 및 그 필름이 융착된 유리를 제공하자 한다. In order to solve the above problems, in the present invention, it is possible to express a variety of patterns and colors on the glass, and the surface is finished with glass not only excellent in wear resistance, chemical resistance and scratch resistance, but also need to form an undercoat layer on the glass Since the manufacturing process is simplified and the adhesion between the glass and the adhesion between layers is excellent, the glass fusion film and semi-permanent product can be manufactured because the printed layer does not peel off even if the glass is broken and the fragments are not dispersed even when exposed to moisture. It is intended to provide a manufacturing method and a glass in which the film is fused.

본 발명의 유리용 융착 필름의 기재층은 폴리에스테르 필름층(10)으로 평활도, 강도면에서 PET백색 필름이 바람직하다. 두께는 요구되는 강도에 따라 적절히 선택하여 사용할 수 있으나, 25 내지 100 마이크로미터의 두께로 하는 것이 바람직하다. 상기 범위 미만이면 강도가 약하고, 상기 범위 이상으로 두꺼우면 접착강도와 평활도가 떨어진다.As for the base material layer of the fusion film for glass of this invention, a polyester white film is preferable in the polyester film layer 10 from a smoothness and an intensity | strength. Although the thickness can be suitably selected and used according to the intensity | strength requested | required, it is preferable to set it as the thickness of 25-100 micrometers. If it is less than the above range, the strength is weak, and if it is thicker than the above range, the adhesive strength and smoothness are inferior.

기재층인 폴리에스테르 필름층의 상면과 하면에 아크릴 코팅층(20,20′)이 형성된다. 아크릴 코팅층은 폴리에스테르 필름과의 접착력이 우수하여 기재층과 분리되지 않으며, 내마모성, 내용제성, 내약품성 및 내스크래치성이 강하여 인쇄층을 보호하는 역할을 한다. 폴리에스테르 필름의 하면에 형성된 아크릴 코팅층은 피사체와 필름을 용이하게 접착시키는 역할을 한다. 본 발명의 일 실시예에 의하면 상기 아크릴 코팅층은 아크릴 수지 20 내지 40중량%를 톨루엔 20 내지 40중량%, 에틸아세테이트 1 내지 10중량% 및 메틸에틸케톤 20 내지 40중량%를 혼합한 용제에 용해하여 얻어진 코팅액을 도포, 건조하여 형성될 수 있다. Acrylic coating layers 20 and 20 'are formed on the upper and lower surfaces of the polyester film layer serving as the substrate layer. The acrylic coating layer is excellent in adhesion to the polyester film and is not separated from the base layer, and serves to protect the printed layer due to strong wear resistance, solvent resistance, chemical resistance, and scratch resistance. The acrylic coating layer formed on the lower surface of the polyester film serves to easily adhere the object and the film. According to an embodiment of the present invention, the acrylic coating layer is dissolved in a solvent in which 20 to 40% by weight of the acrylic resin is mixed with 20 to 40% by weight of toluene, 1 to 10% by weight of ethyl acetate, and 20 to 40% by weight of methyl ethyl ketone. It can be formed by applying and drying the obtained coating liquid.

상기 아크릴 코팅층의 어느 일면에는 수분을 차단하며 아크릴 코팅층과 인쇄층간의 접착력을 증대시켜 인쇄층의 분리를 막는 프라이머층(30)이 형성된다. 본 발명의 일 실시예에 의하면, 상기 프라이머층은 폴리우레탄 수지 15 내지 20중량%, 변성아크릴 수지 10 내지 20중량% 및 실리카분말 2 내지 5중량%를 톨루엔 10 내지 20중량%, 메틸에틸케톤 15 내지 25중량% 및 에틸아세테이트 15 내지 20중량%를 혼 합한 용제에 용해하여 얻어진 프라이머를 도포, 건조하여 형성된다. On one surface of the acrylic coating layer is formed a primer layer 30 to block the separation of water by increasing the adhesion between the acrylic coating layer and the printing layer to prevent separation of the printing layer. According to one embodiment of the present invention, the primer layer is 15 to 20% by weight of polyurethane resin, 10 to 20% by weight of modified acrylic resin and 2 to 5% by weight of silica powder toluene 10 to 20% by weight, methyl ethyl ketone 15 It is formed by applying and drying a primer obtained by dissolving 25 to 25% by weight and 15 to 20% by weight of ethyl acetate in a mixed solvent.

상기 인쇄층의 상면에는 유리와 본 발명의 필름과의 용융접착을 용이하게 하는 접착제층(50)이 형성된다. 본 발명의 일 실시예에 의하면, 상기 접착제층은 폴리우레탄 수지 5 내지 10중량%, 변성 아크릴 수지 10 내지 15중량%, 비닐수지 5 내지 10중량% 및 폴리에틸렌 왁스 2 내지 5중량%를 메틸에틸케톤 25 내지 30중량%, 에틸아세테이트 20 내지 25중량% 및 톨루엔 10 내지 15중량%를 혼합한 용제에 용해하여 얻어진 접착제를 도포,건조하여 형성된다. 접착제층은 피사체의 종류에 따라 그 성분을 다양하게 선택하여 사용할 수 있고, 다른 기능성을 부여하기 위하여 부가제를 선택하여 첨가할 수 있다. 접착제층은 유리와의 접착력을 위해 15마이크로미터 이상으로 형성하는 것이 바람직하다. An adhesive layer 50 is formed on the upper surface of the printing layer to facilitate fusion bonding between glass and the film of the present invention. According to one embodiment of the present invention, the adhesive layer is methyl ethyl ketone of 5 to 10% by weight of polyurethane resin, 10 to 15% by weight of modified acrylic resin, 5 to 10% by weight of vinyl resin and 2 to 5% by weight of polyethylene wax. It is formed by applying and drying the adhesive obtained by dissolving 25-30 weight%, 20-25 weight% of ethyl acetate, and 10-15 weight% of toluene in the mixed solvent. The adhesive layer may be used by variously selecting the components according to the type of the subject, and may be added by selecting an additive in order to impart different functionality. The adhesive layer is preferably formed at 15 micrometers or more for adhesion with glass.

본 발명에 따른 유리용 융착 필름은 접착제층과 인쇄층 및 프라이머층이 모두 폴리우레탄 수지 및 변성아크릴 수지를 톨루엔, 메틸에틸케톤 및 에틸아세테이트를 혼합한 용매에 용해하여 형성되었는 바, 동일재질의 합성수지로 이루어져 층간 접착력이 강하고 아크릴 코팅층 및 프라이머층에 의해 폴리에스테르 필름층, 인쇄층 및 접착제층이 단단하게 한 묶음으로 함침되어 유리가 파손되더라도 파편이 분산되지 않고 인쇄층이 분리되지 않아 반영구적인 제품의 제조가 가능하다. 또한 층간 접착력이 강하므로 수분에 노출시에도 인쇄층의 박리가 일어나지 않는다. In the fusion film for glass according to the present invention, both the adhesive layer, the printing layer, and the primer layer were formed by dissolving a polyurethane resin and a modified acrylic resin in a solvent mixed with toluene, methyl ethyl ketone, and ethyl acetate.
