The mobile phone gradation deco film of the present invention includes a
즉, 본 발명의 휴대폰 그러데이션 데코필름은 도 1에 도시된 바와 같이, 상하 단면을 기준으로 PC PMMA층(110)의 상측으로 그러데이션층(120), UV 패턴인쇄층(130), 증착층(140), 및 실크인쇄층(150)이 차례로 적층된 구조를 가진다.That is, the mobile phone gradation deco film of the present invention is a
베이스 필름인 PC PMMA층(110)은, PC(Polycarbonate)와 PMMA(Polymethyl methacrylate)를 압축하여 복합시트로 형성한 것으로서, 그 두께는 0.5mm가 바람직하다.The PC
PC는 열가소성 플라스틱의 일종. 내충격성, 내열성, 내후성, 자기 소화성, 투명성 등의 특징이 있고, 강화 유리의 약 150배 이상의 충격도를 지니고 있어 유연성 및 가공성이 우수하다. 잘 깨지고 변형되기 쉬운 아크릴의 대용재이자 일반 판유리의 보완재로 많이 쓰인다.PC is a kind of thermoplastic. It has features such as impact resistance, heat resistance, weather resistance, self-extinguishing property, and transparency, and has an impact degree of about 150 times higher than that of tempered glass, so it has excellent flexibility and workability. It is widely used as a substitute for acrylic, which is easily broken and deformable, and as a supplement to general plate glass.
PMMA는 특수 수지(樹脂)의 일종으로, 메칠메타크릴레이트의 폴리머(중합체) 성분이며, 뛰어난 광학 특성, 내후성, 표면강도, 경도, 성형성 등이 특징이다. PMMA, a type of special resin, is a polymer (polymer) component of methyl methacrylate, and is characterized by excellent optical properties, weather resistance, surface strength, hardness, and moldability.
그러데이션층(120)은 베이스 필름인 PC PMMA층(110)에 대하여 잉크젯 방식에 의해 그러데이션(gradation)을 부여한 층이다.The
그러데이션층(120)은 C(cyan), M(magenta), Y(yellow), K(black)의 UV 잉크를 각각 개별 헤드에 의해 잉크젯 방식으로 분사하여 형성된다.The
UV 패턴인쇄층(130)은 그러데이션층(120)에 자외선 인쇄(Ultra-Violet Printing) 방식에 의해 패턴(pattern)이 인쇄되는 층이다.The UV
인쇄용지로 많이 쓰이는 일반 상업지와는 달리 금지, 은지, PP와 같은 재질은 일반지와는 달리 잉크의 침투성이 좋지 않기 때문에 인쇄후 잉크의 건조 속도가 늦고, ?Ⅹ?음이 생기게 되고 잉크가 번지고 인쇄물의 상태가 좋지 않은 문제가 있다.Unlike general commercial papers, which are widely used for printing paper, materials such as Ban, Silver and PP have poor ink permeability unlike regular papers, so the drying speed of the ink after printing is slow, Ⅹ?, and ink bleeding. There is a problem with the printout being bad.
UV 인쇄방식은 상기의 문제점을 보완하기 위한 방식으로, UV 빛에 노출되면서 순간 경화, 즉 바로 건조가 되는 특성이 있는 전용의 액체잉크를 사용하며, 자외선을 이용해 순간 건조하게 되므로 재질의 제약이 없어 다양한 컬러를 표현할수 있으며 탈색과 습기에 강해 외부 날씨 변화 등에 탁월한 내구성을 보장할 수 있다.The UV printing method is a method to compensate for the above problems, and uses a dedicated liquid ink that has the property of instant curing, that is, drying immediately when exposed to UV light, and it is instantaneously dried using ultraviolet rays, so there is no material restriction. It can express various colors, and it is resistant to discoloration and moisture, so it can guarantee excellent durability for external weather changes.
증착층(140)은 UV 패턴인쇄층(150)에 형성되되, 화학적 기상 증착(Chemical Vapor deposition, CVD) 또는 물리적 기상 증착(Physical Vapor Deposition, PVD) 등에 의해 형성될 수 있다.The
제작과정에서 화학반응을 이용하는 화학적 기상 증착은 IC 등의 제조공정에서 기판 위에 실리콘 등의 박막을 만드는 공업적 수법이다. 실리콘 산화막, 실리콘 질소막, 아모퍼스 실리콘(Amorphous Silicon) 박막 등을 만드는데 쓰인다. 화학물질을 포함하는 가스에 열이나 빛으로 에너지를 가하거나, 고주파로 플라스마화시키면 원료 물질이 라디칼화되어 반응성이 크게 높아져서 기판 위에 흡착되어 퇴적한다.Chemical vapor deposition using a chemical reaction in the manufacturing process is an industrial method of making a thin film such as silicon on a substrate in a manufacturing process such as IC. It is used to make silicon oxide film, silicon nitrogen film, and amorphous silicon thin film. When energy is applied to a gas containing a chemical substance with heat or light, or plasma is converted to a high frequency, the raw material is radicalized and the reactivity is greatly increased, and is adsorbed and deposited on the substrate.
물리적 기상 증착 공정은 산화물 반도체나 GaAs 등을 기판에 증착시킬 때 화합물들을 녹여서 고체 상태의 타겟으로 제조해 열이나 전자빔으로 휘발시켜서 기판에 증착시킨다. 이때 원료물질은 열, 레이저, 전자빔 등을 통해 기체상태로 날려서 보내고 날아간 기체 상태의 원료 물질이 기판에 닿았을 때 고체 상태로 변화된다.In the physical vapor deposition process, when an oxide semiconductor or GaAs is deposited on a substrate, compounds are melted and manufactured into a solid target, volatilized with heat or an electron beam, and deposited on the substrate. At this time, the raw material is sent to a gaseous state through heat, laser, electron beam, etc., and is changed to a solid state when the blown gaseous raw material touches the substrate.
