Description
본 발명은 형광등의 반사판으로 사용되는 반사필림제조에 관한 기술로서 더욱 구체적으로는 비극성 소수성의 열가소성 합성수지필림(primer)에 알루미늄 또는 은 등을 증착시켜서되는 형광등 반사판으로 사용되는 적층반사필림제조에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reflective film manufacturing technique used as a reflector for fluorescent lamps, and more particularly, to a laminated reflective film for use as a fluorescent reflector used by depositing aluminum or silver on a non-polar hydrophobic thermoplastic synthetic resin primer. .
종래부터 사용하여온 형광등용 반사판의 종류를 살펴보면 한때 등장한 유리 경면을 이용한 반사갓은 반사율이 극히 우수하긴 하나 유리판위에 은경반응으로 경면을 형성해야하므로 무겁고 원재료가 고가이며 절첩이 되지 않으므로 반사갓형에 따라 절단하여 조립해야하므로 제작비가 크게 상승하게된다.Looking at the type of reflector plate for fluorescent lamps that have been used in the past, the reflection shade using glass mirrors, which appeared once, has very good reflectivity but must be formed on a glass plate by silver mirror reaction. Since the assembly, the production cost will increase significantly.
또 유리면과 은경면은 팽창계수 차이로 온도변화가 되풀이 되는 과정에서 쉽게 간극이 발생하여 간극사이에 습기나 부식개스가 침투하여 부식되므로서 반사효율이 단기간에 떨어져 반사기능을 상실하게된다.In addition, the glass surface and the silver mirror surface have a gap easily generated in the process of repeated temperature change due to the expansion coefficient difference, and moisture or corrosion gas penetrates through the gap.
근간 사무실이나 가정에서 가장 많이 사용하고 있는 금속판에 백색 페인트를 도장한 반사갓은 제작과정이 극히 단순하여 염가이긴 하나 반사율이 좋지않고 도장된 표면이 쉽게 오염되어 빛의 반사효율이 더욱 떨어지게 된다.Reflective shades coated with white paint on the metal plate most commonly used in offices and homes are extremely simple to produce, but they are inexpensive, but the reflectivity is not good and the painted surface is easily contaminated, resulting in less light reflection efficiency.
상기 백색페인트를 도장한 반사갓보다 반사율이 좀더 개선된 것으로는 알미늄판을 양극전해시킨 알루미늄 광택반사판이 최근 선진국에서 개발되어 널리 사용되고 있으나 반사율이 약 90% 정도로서 반사율을 더욱 높히기 위해서는 제조비용이 더욱 상승하며 알루미늄반사판은 직접 대기중에 노출되므로 습기, 부식개스에 쉽게 산화되어 표면이 거칠어지면서 반사율이 떨어지고 내구성이 크게 떨어진다.Although the reflectance is more improved than the reflector coated with the white paint, an aluminum glossy reflector plate made of anodized aluminum plate has recently been developed and widely used in developed countries, but the reflectance is about 90%, and the manufacturing cost is increased to further increase the reflectance. Aluminum reflector is directly exposed to the atmosphere, so it is easily oxidized to moisture and corrosive gas.
그 밖에 본원 발명과 가장 근접한 형광등 반사용 필림이 국내특허공보 98-20697호로 소개되고 있다.In addition, a film for reflecting fluorescent lamps closest to the present invention is introduced in Korean Patent Publication No. 98-20697.
이는 폴리에스텔필림 일측면에 은 또는 알루미늄을 증착시키고 그 위에 접착제가 코팅되어 있으며 폴리에스텔필림의 타측면에는 아크릴보호막을 형성시켜된 필림이다.This is a film formed by depositing silver or aluminum on one side of the polyester film and an adhesive coating thereon, and forming an acrylic protective film on the other side of the polyester film.
이와같은 형광등용 반사필림은 반사율이 거의 98%에 까지 이르고 난반사등이 거의 없는 반사필림이라 할수 있으나 장기간 사용함에 따라 부식에 의한 내구성이 문제가 되고 있다.Such a reflective film for fluorescent lamps can be said to be a reflective film having a reflectance of almost 98% and almost no diffuse reflection, but durability due to corrosion has become a problem as it is used for a long time.
본 발명은 열가소성 합성수지필림에 금속을 증착시킨 적층필림에 있어서 금속증착후의 필림과의 접착성 그리고 필림과 경면의 열팽창계수의 차에 의한 수축과 신장의 반복으로 발생하는 간극을 방지하고 평활한 경면을 형성하는 재질과 수단의 선택으로 우수한 반사율과 내구성을 갖는 형광등 반사판으로 사용되는 금속증착 적층필림을 해결함에 그 목적이 있다 하겠다.The present invention provides a smooth mirror surface to prevent gaps caused by repetition of shrinkage and elongation due to the difference in adhesion between the film after deposition and the thermal expansion coefficient between the film and the mirror in the laminated film in which the metal is deposited on the thermoplastic synthetic resin film. The purpose of the present invention is to solve the metal-deposited laminated film used as a fluorescent reflector having excellent reflectivity and durability by the selection of materials and means to be formed.
본 발명은 국내 특허번호 98-20697 호에 소개된 형광등용 반사필림제조방법의 개량발명에 관한 것으로, 이건 발명에 앞서 상기에서 소개된 선발명의 핵심기술은 플리에스텔필림 일측면에 직접 금속이 접착되어 경면이 형성되고 경면위에 접착층이 형성된 구조로서 경면 양면에 폴리에스텔필림과 접착제층이 적층되어 있는 형광등 반사필림으로 반사효율이 극히 우수하고 제조비용이 염가이여서 현재까지 수년간 당사인 신조명 주식회사에서 생산하고 있는 반사필림이긴 하나 수년간 사용함에 따라 경면과 폴리에스텔필림, 경면과 접착층사이에 간극이 발생하고 이에 따라 간극사이에 수분등 이물질이 침투하고 부식으로 경면의 반사효율이 떨어지면서 문제점을 발생하고 있다.The present invention relates to an improved invention of a method for manufacturing a reflective film for fluorescent lamps, which is introduced in Korean Patent No. 98-20697, which is a core technology of the above-described prior art described above, wherein a metal is directly bonded to one side of a polyester film. It is a structure in which a mirror surface is formed and an adhesive layer is formed on the mirror surface. It is a fluorescent light reflecting film with polyester film and adhesive layer laminated on both sides of the mirror, and its reflection efficiency is extremely excellent and manufacturing cost is low. Although it is a reflective film that has been used for many years, a gap occurs between the mirror surface and the polyester film, the mirror surface and the adhesive layer, and thus foreign matters such as moisture penetrate between the gap and the reflection efficiency of the mirror surface decreases due to corrosion.
본 발명자는 다년간에 걸친 경험과 실험을 통하여 선발명의 문제점을 해결하기에 이르렀다.The present inventors have come to solve the problem of the selection through many years of experience and experiment.
즉, 문제점의 원인은 반사필림의 경면양면에 적층합성수지재질과 경면과의 점등 및 소등에의한 열변화에 따른 열팽창계수의 차이가 크므로서 신장수축시 각 재질층의 면과 면사이에 상당한 전단력이 발생 장기간에 걸쳐 반복되므로서 결국에 가서는 층과 층사이에 간극이 발생하게 되고 이로서 수분 및 개스등이 침투하여 부식이 발생하고 반사율이 감소하는 원인이 되며 또하나의 원인은 경면을 둘러싼 접착제층이나 폴리에스텔필림등 재질의 물과의 친화성 정도에도 영향을 받게됨을 확신하게되었다.That is, the cause of the problem is that the difference in the coefficient of thermal expansion due to the heat change due to the light on and off of the laminated synthetic resin material and the mirror surface on the mirror surface on both sides of the reflective film is large, so that the shearing force between the surfaces of the layers of each material layer during stretching This phenomenon is repeated over a long period of time, and eventually, a gap is generated between layers, which causes water and gas to penetrate, causing corrosion and decreasing reflectance. Another cause is adhesives surrounding mirror surfaces. I was convinced that the degree of affinity with water, such as layers and polyester films, would also be affected.
결국 본 발명은 위와같은 선발명을 개선한 방법으로 우선 경계면을 에워싸는합성수지재질이 소수성이면서 열변형으로 상호층간에 발생하는 전단력을 완충시켜 줄수 있는 재질선택이 핵심적인 기술로서 이를 구체적으로 설명하면 폴리에스텔필림 일면에 비극성 소수성의 열가소성수지(프라이머)용융액 또는 용액을 라미네이트방법으로 피막을 형성시킨 다음 이 피막층위에 금속진공증착 방법으로 경면을 형성시키고 이 경면위에 상기와 같은 동일한 수지로 다시 코팅하여 피막을 형성 적층시키고 그 위에 접착층을 형성시켜서된 형광등용 반사갓의 제조방법이라 할수 있다.As a result, the present invention is a method of improving the selection of the above, and the material selection that can buffer the shear force generated between the layers due to the hydrophobicity and thermal deformation of the synthetic resin material surrounding the interface is described as the core technology. A film of nonpolar hydrophobic thermoplastic resin (primer) melt or solution is formed on one surface of the film by laminating method, and then a mirror surface is formed on the film layer by metal vacuum deposition method, and the film is coated on the mirror surface again with the same resin as above. It can be said to be a method of manufacturing a reflector for fluorescent lamps by laminating and forming an adhesive layer thereon.
상기 본 방법에서 중요한 것은 경면을 샌드위치 상으로 적층시키는 양면 재질이 동일해야하고 비친수성 또는 발수성의 합성수지이어야 하며, 항상 점성과 탄성이 존재하여 층간에 발생하는 전단력을 흡수 완충시켜줄수 있는 합성수지 재질이어야 한다.It is important in the present method that the two-sided material for laminating the mirror surface onto the sandwich should be the same, and it should be a non-hydrophilic or water-repellent synthetic resin. .
이와 같은 합성수지는,에폭시/알킬에스텔, 염화비닐/초산비닐공중합체, 폴리비닐부치랄, 폴리우레탄고무등이라 할수 있으며 금속증착에 사용되는 금속은 은(Ag), 알루미늄(Al), 닉켈(Ni), 크롬(Cr), 티타니움(Ti) 등을 사용할수 있으며 증착방법은 E-Beam 진공중착법, R-F-Sputtering 법, Bias Sputtering(Ion-plating)등의 진공증착법을 금속이나 필림의 특성, 요구되는 증착 부착력에 따라 선택 사용할수 있다.Such synthetic resins may be referred to as epoxy / alkyl esters, vinyl chloride / vinyl acetate copolymers, polyvinyl butyral, polyurethane rubbers, and the metals used for metal deposition are silver (Ag), aluminum (Al), and nickel (Ni). ), Chromium (Cr), titanium (Ti), etc. can be used, and the deposition method is a vacuum deposition method such as E-Beam vacuum deposition method, RF-Sputtering method, Bias Sputtering (Ion-plating), etc. It can be used depending on the deposition adhesion.
그 밖에 경면 양면에 형성되는 피막층은 합성수지를 열용융시킨 상태나 용제에 용해시킨 상태로서 라미네이트 방법으로 직접 코팅하여 피막층을 형성시킬수도 있지만 이형지의 평활한 이형면에 코팅하여 피막을 형성시킨다음 피막을 전사하는 방법으로 피막층을 형성시킬수도 있다.In addition, the coating layer formed on both sides of the mirror surface may be formed by heat-melting synthetic resin or dissolving in a solvent, and by directly coating by lamination method to form a coating layer, but by coating on a smooth release surface of the release paper to form a coating film. A film layer can also be formed by the method of transferring.
이는 작업성이 용이하고 평활한 면이 형성되어 난반사를 철저히 방지할수 있다.It is easy to work and smooth surface is formed, it is possible to thoroughly prevent diffuse reflection.
본 발명은 비극성 소수성의 열가소성수지(프라이머)를 사용하므로서 발수성이 있어 수분의 흡수접근을 철저히 방지할수 있고, 점탄성이 있어 온도 변화에 따른 층간에 발생하는 전단력을 흡수 완충시킬수 있으며 경면을 중심으로 양면에 적층되는 피막층을 동일재질로 구성하므로서 더욱 전단력의 발생을 효과적으로 줄일수 있게되어 장기 사용해도 간극이 발생하지 않아 반영구적이라 할수 있는 형광등용 반사필림이라 할수 있다.The present invention is water-repellent by using a non-polar hydrophobic thermoplastic resin (primer) to prevent water absorption approach thoroughly, viscoelasticity can absorb and buffer the shear force generated between layers due to temperature changes, and on both sides of the mirror surface Since the laminated film layer is made of the same material, it is possible to effectively reduce the generation of shear force, and thus it is a semi-permanent reflective film for semi-permanent because there is no gap even after long-term use.
이상의 본 발명에 의한 형광등용 반사필림의 효과를 더욱 분명히 하기 위해 실시예로 나타내었다.In order to clarify the effect of the reflective film for a fluorescent lamp according to the present invention is shown in the Examples.
〈실시예〉<Example>
30μ 두께의 폴리에스텔필림 일면에 염화비닐/초산비닐공중합수지를 2μm 두께로 코팅하고 코팅피막층을 건조 안정화시킨후 10-5-10-6Torr 진공으로 유지시킨 상태에서 은을 증착시킨다음 2μm 두께로 위와 동일한 수지를 2μm 두께로 피막층을 형성시킨후 그 위에 비흡수성의 아크릴계 점착제를 코팅한후 탈지처리한 알루미늄판(0.4mm)에 4kg/㎠ 압으로 접착시켜서된 형광등용 반사갓시편을 얻었다.Coated vinyl chloride / vinyl acetate copolymer resin with a thickness of 2μm on one surface of 30μ thick polyester film, and the coating film layer was dried and stabilized, and then silver was deposited while maintaining the vacuum at 10 -5 -10 -6 Torr to 2μm thickness. Reflective specimens for fluorescent lamps were obtained by forming a coating layer having a thickness of 2 μm and coating a non-absorbing acrylic pressure-sensitive adhesive thereon, and then attaching the same resin to a degreasing aluminum plate (0.4 mm) at 4 kg / cm 2.
이 반사 필림과 국내특허공개공보 98020697호에 의한 본사제품 형광등용 반사필림으로 평균조도, 반사율, 내구성(부식성)등 3개항목을 측정한 결과 아래와 같은 물성 비교표를 얻었다.As a result of measuring three items such as average illuminance, reflectance, and durability (corrosiveness) with the reflecting film and the reflecting film for the fluorescent lamp of our company according to Korean Patent Publication No. 98020697, the following physical property comparison table was obtained.
반사필림물성 비교표Reflective film property comparison table
이상과 같이 본발명에 의한 형광등용 반사필림은 종래 필림에 비해 평균조도, 반사율에 있어서는 거의 동일하나 내구성은 거의 2배로 연장된 것을 알수 있다.As described above, the reflective film for the fluorescent lamp according to the present invention is almost the same in terms of average illuminance and reflectance as compared to the conventional film, but the durability is almost doubled.
