Description
본 발명은 자동차의 유리에 부착시키는 틴팅필름에 관한 것으로, 더욱 상세하게는 태양광의 자외선과 열선을 차단하는 동시에 외부충격에 의해 유리창이 갑작스럽게 파손될 경우, 유리파편의 비산을 방지함으로서 안전사고를 방지할 수 있는 이중 펌핑 펌핑 장치를 이용한 틴팅필름의 제조 방법에 관한 것이다.The present invention relates to a tinting film to be attached to the glass of a car, and more particularly, it blocks ultraviolet rays and heat rays of sunlight, and at the same time prevents safety accidents by preventing the scattering of glass fragments when a glass window is suddenly damaged by an external impact It relates to a method of manufacturing a tinting film using a double pumping pumping device that can do it.
썬팅은 자동차나 건축물의 투명한 유리에 자외선 차단 등을 위한 틴팅필름을 부착하는 작업을 말한다.Tinting refers to the operation of attaching a tinting film to the transparent glass of a car or building to block UV rays.
특히, 차량에 있어서 전면과 뒷면 및 좌우의 측면에는 차량의 내부와 외부의 상황을 쉽게 파악하기 위해 투명한 유리창이 설치되고, 이 투명한 유리창은 차량 내외부의 상황을 쉽게 파악할 수 있도록 하며 안전운전을 도모하기에 차량에는 투명한 유리를 사용하여 공장에서 출하되어 소비자에게 전달되게 된다.In particular, transparent glass windows are installed on the front, rear, and left and right sides of a vehicle to easily understand the inside and outside conditions of the vehicle, and this transparent glass window makes it easy to understand the inside and outside conditions of the vehicle and promotes safe driving. In the vehicle, transparent glass is used to be shipped from the factory and delivered to the consumer.
하지만 유리창이 투명하기 때문에 태양광선에 직접적으로 노출되는 불편함이 있을 뿐아니라, 더욱이 차량내부로 조사되는 햇빛은 사람의 피부를 태우고 이러한 자외선은 의해 각종 피부질환을 유발시키는 문제점이 있을 뿐아니라, 차량 내부로 조사되는 햇빛은 운전자 및 동승자의 시야를 흐려서 안전운전을 방해하는 문제점이 있었다.However, since the glass window is transparent, there is the inconvenience of being directly exposed to sunlight, and moreover, the sunlight irradiated into the vehicle burns the human skin, and there is a problem in that these ultraviolet rays cause various skin diseases. The sunlight irradiated into the interior obscured the driver's and passenger's vision, thereby obstructing safe driving.
상기와 같은 이유로, 소비자는 공장 출하시에 차량에 장착된 투명 유리에 틴팅필름을 부착함으로써 내부로 들어오는 가시광선을 적당한 정도로 차단하여 햇빛에 의한 눈부심을 방지하여 안전운전을 도모할 뿐아니라, 실내에서 안락한 분위기를 연출할 수 있고 외부로부터 시선 차단 효과와 차량이 품위있게 보이도록 하기 위해 틴팅필름을 이용한 썬팅을 많이 한다.For the above reasons, consumers not only promote safe driving by preventing glare from sunlight by blocking visible light entering the interior to an appropriate degree by attaching a tinting film to the transparent glass installed in the vehicle at the time of shipment from the factory, but also promote safe driving indoors. A lot of tinting is done using a tinting film to create a comfortable atmosphere and to block the eyes from the outside and make the vehicle look elegant.
또한, 상기 틴팅필름을 이용한 썬팅은 자외선을 차단하여 피부보호 및 물품의 탈색을 방지하고 적외선을 차단하여 차량내부의 열 발생량을 최소화할 수 있도록 한다.In addition, the tinting using the tinting film blocks ultraviolet rays to protect the skin and prevent discoloration of articles, and to minimize the amount of heat generated inside the vehicle by blocking infrared rays.
이러한 틴팅필름으로는 일반적으로 우수한 물리적, 화학적 특성을 가지고 있어 고분자 가공제품으로 광범위하게 사용되고 있는 PET(polyethylene terephthalate)를 기본적인 지지체로 사용하는데, 태양광을 차단할 뿐만 아니라 PET 필름의 강한 물성 때문에 창유리에 대한 안전 강화용으로 이용되어지고 있으며, 이것은 지지체로 사용되는 PET 필름의 강한 물성 및 접착력에 의하여 수행되어 진다.As such a tinting film, PET (polyethylene terephthalate), which is widely used as a polymer processing product because it has excellent physical and chemical properties, is used as a basic support. It is used for safety reinforcement, and this is performed by the strong physical properties and adhesion of the PET film used as a support.
한편, 이러한 지지체로 PET 필름을 차량에 사용되는 경우에는 PET 필름이 가지고 있는 물성치보다 더 필요한 경도 강화와 사생활 보호 등을 위해서 추가적인 코팅층을 형성하고 있는데, 코팅층의 형성시에 코팅층 두께의 비균일성으로 인하여 빛의 난반사 등의 품질 불량이 발생되는 문제점이 있다.On the other hand, when a PET film is used as such a support for a vehicle, an additional coating layer is formed to strengthen the hardness and protect privacy, which are more necessary than the physical properties of the PET film. Due to this, there is a problem in that quality defects such as diffuse reflection of light occur.
본 발명은 상기한 종래기술의 문제점을 해결하기 위한 것으로서, 틴팅필름에 사용되기 위하여 공급되는 코팅제의 공급시 공급 압력에 의한 코팅제의 맥동을 줄여 코팅시 코팅층 두께의 균일성을 확보할 수 있는 틴팅필름 제조 방법을 제공하는 것이다.The present invention is to solve the problems of the prior art, and to reduce the pulsation of the coating agent due to the supply pressure when supplying the coating agent supplied to be used in the tinting film, thereby securing the uniformity of the coating layer thickness during coating. To provide a manufacturing method.
또한, PET층 사이에 카본층 또는 염료층과 PET층 일면인 외부와 맞닿는 면에 유리막층을 형성함으로써, 기본적인 PET의 물리적, 화학적 특성 뿐만아니라 카본과 유리막의 추가적 특성으로 인한 뛰어난 태양광의 차단와 색상과 경도 강화를 확보할 수 있는 틴팅필름 제조 방법을 제공하는 것이다.In addition, by forming a glass film layer on the surface that is in contact with the outside, which is one surface of the carbon layer or the dye layer and the PET layer, between the PET layer, not only the basic physical and chemical properties of PET, but also excellent blocking of sunlight due to the additional properties of carbon and glass film, color and An object of the present invention is to provide a method for manufacturing a tinting film capable of securing hardness enhancement.
상기한 목적을 달성하기 위하여 본 발명은, 틴팅필름에 있어서, 제1 PET 원단의 일면에 카본 코팅을 수행하는 1차 코팅 단계, 상기 1차 코팅 단계를 거쳐 나온 카본층의 제1 PET 원단이 부착되지 않은 면에 제2 PET 원단의 일면을 부착하는 PET 부착 단계, 상기 제1 PET 원단의 카본층이 형성되지 않은 타면에 유리막 코팅층을 형성하는 유리막 코팅 단계, 상기 제2 PET 원단의 카본층과 접합되지 않은 타면에 점착제를 도포 또는 적층하는 단계, 상기 도포 또는 적층된 점착제에 보호필름을 부착하는 단계로 이루어진다.In order to achieve the above object, the present invention, in the tinting film, a first coating step of performing carbon coating on one surface of the first PET fabric, and the first PET fabric of the carbon layer that has passed through the first coating step is attached PET attachment step of attaching one side of the second PET fabric to the non-coated side, a glass film coating step of forming a glass film coating layer on the other surface where the carbon layer of the first PET fabric is not formed, bonding with the carbon layer of the second PET fabric It consists of a step of applying or laminating an adhesive on the other surface that is not, and attaching a protective film to the applied or laminated adhesive.
또한, 상기 1차 코팅 단계와 상기 PET 부착 단계 사이에 제1 건조단계가 더 추가되며, 상기 1차 코팅 단계와 상기 유리막 코팅 단계는 이중 펌핑 장치를 사용하여 코팅을 수행한다.In addition, a first drying step is further added between the first coating step and the PET attachment step, and the first coating step and the glass film coating step are performed by using a double pumping device.
이때, 상기 이중 펌핑 장치는 코팅액 저장부의 코팅액을 공급하기 위한 펌프와, 이에 연결된 코팅액 유입홀과 코팅액 과대 높이를 제한하기 위며 코팅액 저장부와 연결된 코팅액 유출홀과 코팅액 유입홀 전면에 설치되고 저면이 개방된 차단판을 갖춘 코팅액 수용용기와, 상기 코팅액 수용용기 내부에 설치되어 저면 일부가 코팅액에 닿는 롤러로 이루어진다.At this time, the double pumping device is installed in front of the pump for supplying the coating solution of the coating solution storage unit, the coating solution inlet hole connected thereto, and the coating solution excessive height. It consists of a coating solution receiving container equipped with a blocking plate, and a roller installed inside the coating solution receiving container and whose bottom surface is partially in contact with the coating solution.
본 발명에 의하면, 이중 펌핑 장치에 의해서 공급되는 코팅제는 코팅제 유입시 유입 압력에 의한 맥동이 감소되어 일정한 높이를 유지하므로, 코팅층 두께의 균일성을 확보할 수 있다.According to the present invention, since the coating agent supplied by the double pumping device maintains a constant height by reducing pulsation due to the inflow pressure when the coating agent is introduced, it is possible to secure the uniformity of the coating layer thickness.
또한, PET층 사이에 카본층과 PET층 일면에 유리막층으로 인하여 뛰어난 자외선 차단과 고경도의 틴팅필름을 제공할 수 있다.In addition, it is possible to provide a tinting film with excellent UV protection and high hardness due to the carbon layer between the PET layer and the glass film layer on one surface of the PET layer.

본 발명에 대해 첨부된 도면을 참조하여 상세히 설명하면 다음과 같다. 여기서, 동일한 구성에 대해서는 동일부호를 사용하며, 반복되는 설명, 본 발명의 요지를 불필요하게 흐릴 수 있는 공지 기능 및 구성에 대한 상세한 설명은 생략한다. 본 발명의 실시형태는 당업계에서 평균적인 지식을 가진 자에게 본 발명을 보다 완전하게 설명하기 위해서 제공되는 것이다. 따라서, 도면에서의 요소들의 형상 및 크기 등은 보다 명확한 설명을 위해 과장될 수 있다.The present invention will be described in detail with reference to the accompanying drawings as follows. Here, the same reference numerals are used for the same components, and repeated descriptions and detailed descriptions of well-known functions and configurations that may unnecessarily obscure the gist of the present invention will be omitted. The embodiments of the present invention are provided in order to more completely explain the present invention to those of ordinary skill in the art. Accordingly, the shapes and sizes of elements in the drawings may be exaggerated for clearer description.
이하, 첨부된 도면을 참조하여 본 발명의 바람직한 실시예를 상세히 설명한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
도 1에서 보는 바와 같이, 차량용 썬팅에 사용되는 틴팅필름(100)은 카본층(130)의 위, 아래로 제1, 2 PET층(120,140)이 형성되고 제1 PET층 위로는 유리막(110)층이 제2 PET층 아래로는 점착제층(150)이 형성되며 점착제층 아래로 보호필름(160)이 부착된다.As shown in FIG. 1 , in the
상기 PET층은 합성 섬유 소재인 PET를 원단 형태로 공급되며, 원단 제조 과정에서 광을 차단하는 시료를 첨가하여 제조될 수 있다.The PET layer is a synthetic fiber material, PET, is supplied in the form of a fabric, and may be prepared by adding a sample that blocks light during the fabric manufacturing process.
한편, 추가적인 자외선 차단과 칼라를 위한 제1, 2 PET층 사이의 카본층을 대신에 다양한 색상을 구현할 수 있는 염료층으로 대체하는 것도 가능하다.Meanwhile, it is also possible to replace the carbon layer between the first and second PET layers for additional UV protection and color with a dye layer capable of implementing various colors.
이렇게 틴팅필름의 최상층에 유리막층을 형성함으로써, 외부에 노출된 면의 광택 유지와 더불어 자연 오염물 제거에 효과적이다.By forming a glass film layer on the top layer of the tinting film in this way, it is effective in maintaining the gloss of the surface exposed to the outside and removing natural contaminants.
또한, 점착제층에 부착되는 보호필름의 일면에는 실리콘 코팅층(161)이 있어 보호필름의 제거시 매끄럽고 용이한 제거에 도움을 주게 된다.In addition, since there is a silicone coating layer 161 on one surface of the protective film attached to the pressure-sensitive adhesive layer, it helps smooth and easy removal when the protective film is removed.
이렇게 다층으로 형성된 틴팅필름을 차량의 앞, 뒤 및 좌,우 유리면에 썬팅하는 경우에는 보호필름층를 벗겨내고 차량의 유리면에 접착제층이 부착되도록 하면 차량의 썬팅이 완성되는 것이다.In the case of tinting the tinting film formed in multiple layers on the front, rear and left and right glass surfaces of the vehicle, the tinting of the vehicle is completed by peeling off the protective film layer and allowing the adhesive layer to be attached to the vehicle glass surface.
도2는 이러한 틴팅필름의 제조단계를 나타내고 있다.2 shows the manufacturing steps of such a tinting film.
제공된 제1 PET 원단을 카본 코팅제가 공급되는 이중 펌핑 코팅 장치로 공급하여 제1 PET 원단의 일면에 카본 코팅을 수행하는 1차 코팅 단계(S10)를 거치게 된다.The provided first PET fabric is supplied to a double pumping coating device to which a carbon coating agent is supplied, and a primary coating step (S10) of performing carbon coating on one surface of the first PET fabric is performed.
이중 펌핑 코팅 장치(200)는, 코팅액 저장부(210)의 코팅액을 공급하기 위한 펌프(220)와, 이에 연결된 코팅액 유입홀(230)과 코팅액 과대 높이를 제한하기 위며 코팅액 저장부와 연결된 코팅액 유출홀(240)과 코팅액 유입홀 전면에 설치되고 저면이 개방된 차단판(260)을 갖춘 코팅액 수용용기(250)와, 상기 코팅액 수용용기 내부에 설치되어 저면 일부가 코팅액에 닿는 롤러(270)로 이루어진다.Double
즉, 공급된 PET 원단이 이중 펌핑 코팅 장치의 코팅액 수용용기 내로 공급되게 되면서 롤러와 접촉하게 되고, 롤러가 회전하면서 롤러 표면에 묻어 있던 코팅액이 공급된 PET 원단의 일면에 묻게 되어 코팅이 되게 된다.That is, the supplied PET fabric comes into contact with the roller as it is supplied into the coating solution container of the double pumping coating device, and as the roller rotates, the coating solution on the surface of the roller is deposited on one surface of the supplied PET fabric to be coated.
이렇게 코팅액이 PET 원단에 묻어 소비되게 되므로 계속적으로 코팅액이 코팅액 수용용기 내로 공급될 필요가 있게 된다.Since the coating solution is consumed on the PET fabric in this way, it is necessary to continuously supply the coating solution into the coating solution container.
따라서, 코팅액 수용용기로 코팅액을 공급하기 위해서 펌프가 작동하게 되어 코팅액 저장부에 있는 코팅액은 코팅액 유입홀을 통하여 코팅액 수용용기로 공급되게 되는데, 이러한 펌프의 작동에 따른 유입되는 코팅액은 압력에 의해서 맥동이 발생되므로 이로 인한 코팅액 수용용기의 코팅액의 높이는 미세하지만 변화가 발생되어 롤러에 묻혀지는 코팅액의 차이가 발생되고 이로 인한 코팅면의 두께의 불균형이 발생되게 된다.Accordingly, the pump is operated to supply the coating solution to the coating solution receiving container, and the coating solution in the coating solution storage unit is supplied to the coating solution receiving container through the coating solution inlet hole. Since this occurs, the height of the coating solution in the coating solution container is minute, but a change occurs, and a difference in the coating solution applied to the roller occurs, resulting in an imbalance in the thickness of the coating surface.
그러므로 롤러에 묻혀지는 코팅액을 일정하도록 하기 위해서는 코팅액 수용용기로 코팅액이 유입될 때 유입 코팅액의 맥동에 의한 코팅액 수용용기의 코팅액 높이 변화를 최소로 하는 것이 필요하게 되어, 코팅액 유입홀 앞에 차단판(260)을 설치하고 이로 인하여 압력이 걸려 맥동되는 유입 고팅액이 1차적으로 차단판에 부딪힌 후 압력이 떨어지고 맥동량이 감소하게 한 후 차단판의 아래 틈을 통하여 코팅액 수용용기로 유입되도록 하였다.Therefore, in order to keep the coating liquid buried on the roller constant, it is necessary to minimize the change in the coating liquid height in the coating liquid container due to the pulsation of the influent coating liquid when the coating liquid flows into the coating liquid container. ) was installed, and the inflow coating solution pulsating due to pressure first collided with the blocking plate, then the pressure dropped and the amount of pulsation decreased, and then flowed into the coating solution container through the gap below the blocking plate.
이러한 차단판은 여러겹으로 함으로써 차단판의 아래 틈을 통하여 흐르는 코팅액의 흐름을 더욱 안정적으로 할 수 있으므로 코팅액 높이의 떨림을 더욱 줄일 수 수 있다.By forming such a barrier plate in multiple layers, the flow of the coating liquid flowing through the gap under the barrier plate can be made more stable, so that the vibration of the coating liquid level can be further reduced.
한편, 소비되는 코팅액 보다 과도한 코팅액이 유입되는 경우에도 코팅액 수용 용기내의 코팅액 높이가 높아져 롤러와 접촉되는 코팅액의 높이가 변화되어 코팅 두께의 변화가 발생된다.On the other hand, even when an excessive amount of coating solution flows in than the coating solution consumed, the height of the coating solution in the coating solution accommodating container is increased and the height of the coating solution in contact with the roller is changed, resulting in a change in the coating thickness.
따라서, 코팅액 수용 용기 내의 코팅액 높이를 일정하게 유지할 필요가 있게 되므로 코팅액 수용용기 상단에 코팅액 유출홀을 두어 코팅액 수용용기 내의 과도한 코팅액이 이를 통해 코팅액 저장부로 흘러 나가도록 하여, 코팅액 수용용기 내의 코팅액 높이를 일정하게 유지할 수 있도록 하였다.Therefore, since it is necessary to maintain a constant level of the coating solution in the coating solution container, a coating solution outlet hole is provided at the top of the coating solution container so that the excess coating solution in the coating solution container flows out to the coating solution storage unit. to keep it constant.
이러한 이중 펌핑 장치는 사용 코팅제의 종류만 변경함으로써 모든 코팅과정에서 사용 가능하다.This double pumping device can be used in all coating processes by changing only the type of coating agent used.
한편, 상기 1차 코팅 단계를 거쳐 나온 제1 PET 원단의 일면에 카본이 코팅된 카본층의 제1 PET 원단이 부착되지 않은 타면에 제2 PET 원단의 일면을 부착하는 PET 부착 단계(S20)를 거친다.On the other hand, the PET attaching step (S20) of attaching one side of the second PET fabric to the other side to which the first PET fabric is not attached of the carbon layer coated with carbon on one side of the first PET fabric that has been passed through the first coating step. rough
이렇게 1차 코팅 단계를 거쳐 카본층이 일면에 코팅된 제1 PET 원단의 카본층은 묽은 상태로 코팅되어 있어 제2 PET 원단을 부착하기에는 접착력이 적어 제2 PET원단과의 접착에 어려움이 있을 수 있으므로, 접착력 향상을 위해서 이들 1차 코팅단계와 제2 PET 원단을 부착하는 PET 부착 단계 사이에는 제1 건조단계가 더 추가 될 수 있다.In this way, the carbon layer of the first PET fabric with the carbon layer coated on one side after the first coating step is coated in a thin state, so there may be difficulties in adhesion with the second PET fabric because the adhesive strength is low to attach the second PET fabric. Therefore, in order to improve adhesion, a first drying step may be further added between the first coating step and the PET attachment step of attaching the second PET fabric.
상기 제1 건조단계는 1차 코팅 단계에서 카본층이 형성된 제1 PET 원단이 건조 챔버를 지나게 되는 것으로, 제 2 PET 원단이 부착하기에 적절한 점도를 가지도록 카본층에 포함된 솔벤트를 증발시켜 카본층이 요구되는 접착력을 가질 수 있도록 하는 것이다.In the first drying step, the first PET fabric on which the carbon layer is formed in the first coating step passes through a drying chamber, and the solvent contained in the carbon layer is evaporated to have an appropriate viscosity for attaching the second PET fabric to the carbon layer. This is to ensure that the layer has the required adhesive strength.
이러한 제1 건조단계에 사용되는 건조 챔버의 길이는 28m이며, 건조 챔버에서는 열풍에 의한 건조로서 열풍 온도는 120 ~ 160℃이며, 카본층이 코팅된 제1 PET 원단은 40 ~ 60 m/sec의 속도로 챔버내에서 흐르게 되고, 최종적으로 건조되어 나오는 카본층에 포함된 솔벤트는 5% 내외를 가지게 된다.The length of the drying chamber used in this first drying step is 28 m, and in the drying chamber, the hot air temperature is 120 ~ 160 ° C. It flows in the chamber at a high speed, and the solvent contained in the carbon layer that is finally dried has about 5%.
이렇게 제1 PET원단과 제2 PET원단 사이에 카본층이 형성된 필름의 제1 PET 원단의 카본층 반대면인 타면에 틴팅필름의 경도 향상을 위해서 유리막 코팅층을 형성하는 유리막 코팅 단계(S30)를 거치게 된다.In this way, the glass film coating step (S30) of forming a glass film coating layer to improve the hardness of the tinting film on the other surface of the film on which the carbon layer is formed between the first PET fabric and the second PET fabric is opposite to the carbon layer of the first PET fabric. do.
이러한 유리막 코팅은 통상적으로 잘 알려진 마이크로 그라비어 코팅 방법을 사용하여 코팅층의 두께가 2~3㎛가 되도록 수행하는 것이 일반적이지만, 앞서 설명한 이중 펌핑 장치를 사용하여 유리막 코팅을 수행할 수도 있다.The glass film coating is generally performed so that the thickness of the coating layer is 2 to 3 μm using a well-known micro gravure coating method, but the glass film coating can also be performed using the double pumping device described above.
한편, 이렇게 유리막 코팅을 한 후에는 코팅층의 빠른 건조를 위한 건조 단계를 거칠 수 있는데, 이때의 건조도 제1 건조단계와 마찬가지로 120 ~ 160℃의 열풍 건조를 수행하거나 UV건조를 수행하며, 이때 틴팅필름은 60 m/sec의 속도로 이송하게 된다.On the other hand, after coating the glass film in this way, a drying step for quick drying of the coating layer may be performed. In this case, as in the first drying step, hot air drying at 120 to 160° C. or UV drying is performed, and at this time, tinting is performed. The film is transported at a speed of 60 m/sec.
이렇게 유리막 코팅까지 마친 틴팅필름에 보호필름을 부착하기 위하여 카본층이 형성되지 않은 제2 PET 원단의 타면에 점착제 도포 또는 적층하는 단계(S40)를 거치게 되고, 이 도포 또는 적층된 점착제에 보호필름 부착 단계(S50)를 거쳐 보호필름까지 부착된 틴팅필름의 원단이 완성되는 것이다.In order to attach the protective film to the tinting film that has been coated with the glass film in this way, a step (S40) of applying or laminating an adhesive on the other side of the second PET fabric on which a carbon layer is not formed is performed, and a protective film is attached to the applied or laminated adhesive. The fabric of the tinting film attached to the protective film through the step (S50) is completed.
한편, 점착제에 부착되는 보호필름은 점착제와 맞닿는 면에 실리콘 코팅이 되어 있는 것을 사용할 수 있는데, 이는 썬팅시 보호필름의 제거시 점착제 표면에 깨끗한 이탈면을 형성하게 하고 보호필름의 제거가 용이하게 하도록 하기 위함이나, 반드시 실리콘 코팅이 된 보호필름일 필요는 없다.On the other hand, the protective film attached to the pressure-sensitive adhesive can be used with a silicone coating on the surface in contact with the pressure-sensitive adhesive, which forms a clean release surface on the surface of the pressure-sensitive adhesive when removing the protective film during tanning and facilitates the removal of the protective film. In order to do this, it is not necessarily a protective film coated with silicone.
이렇게 완성된 틴팅필름의 원단은 필요한 폭과 길이로 절단공정을 거쳐서 소비자에게 제공되게 된다.The fabric of the tinting film thus completed is provided to the consumer through a cutting process to the required width and length.
