Description
본 발명은 플라스틱 거울에 관한 것으로, 더욱 상세하게는 플라스틱 사출물의 양면에 용융 알루미늄(Al)을 진공코팅하여 반사물질을 코팅하고 반사코팅면 양면의 상부에 하드코팅을 하여 플라스틱 사출물이 양면거울의 기능을 갖도록 한 플라스틱 양면 거울 및 그 제조방법에 관한 것이다.The present invention relates to a plastic mirror, and more specifically, to a reflective coating by vacuum-coating molten aluminum (Al) on both sides of the plastic injection molding, and hard coating on the upper surface of both sides of the reflective coating, the plastic injection molding function of a double-sided mirror It relates to a plastic double-sided mirror and a method of manufacturing the same.
일반적인 유리 거울은 빛이 매질을 통과할 때의 굴절율이나 유리 거울 후면의 반사코팅에 의해 선명성이 떨어지며, 도 1은 이러한 유리를 이용한 양면 거울의 구성도를 도시한 것이다.The general glass mirror is inferior in clarity due to the refractive index of the light passing through the medium or the reflection coating on the back of the glass mirror, Figure 1 shows a block diagram of a double-sided mirror using such glass.
이에 도시한 바와 같이, 오목면(1)과 평면(2)의 후면에는 각각 반사코팅 물질에 의한 반사코팅면(3)이 형성되며, 상기 오목면(1)과 평면(2)의 반사코팅면(3)이 접착제에 의해 결합되어 양면거울이 형성되며, 보통 유리 거울의 소재는 창유리라 불리는 창호에 사용되는 재질들이며, nd는 약 1.51정도이다.As shown in the figure, a reflective coating surface 3 is formed on the rear surface of the concave surface 1 and the plane 2 by a reflective coating material, respectively, and the reflective coating surface of the concave surface 1 and the plane 2 is formed. (3) It is bonded by this adhesive to form a double-sided mirror, and the materials of glass mirrors are the materials used for windows and doors called window glass, and nd is about 1.51.
그러나 이러한 유리 거울은 도 2에 도시한 빛의 굴절도에서와 같이, 빛이 입사하게 되면 유리의 굴절율에 따라 빛이 굴절하여 반사코팅면(3)에서 반사하며, 이때 유리표면에서 빛의 굴절로 인한 표면 반사 현상이 생기며, 이때의 반사와 반사코팅면(3)에서의 반사에서 고스트(Ghost) 화상이 생겨 상의 선명성이 결여되게 된다.However, such glass mirrors, as shown in the refractive index of the light shown in Figure 2, when the light is incident, the light is refracted according to the refractive index of the glass and reflected on the reflective coating surface 3, at this time due to the refraction of the light on the glass surface A surface reflection phenomenon occurs, and a ghost image is generated at the reflection and reflection at the reflection coating surface 3, thereby lacking the sharpness of the image.
또한, 유리 거울은 후면에 반사코팅을 함으로써 표면의 반사로 인한 착시현상이 생겨 선명성이 떨어진다.In addition, the glass mirror is subjected to the reflective coating on the back, causing optical illusion due to the reflection of the surface, resulting in poor clarity.
그리고 이러한 종래의 양면 거울은 접착제를 이용하여 양면 거울을 만들므로써 접착부위가 떨어져 양면 거울의 기능을 행하지 못하게 될 수 있을 뿐만아니라, 유리로 만들어지므로 파손이나 무게감으로 인해 소지에 불편함이 따랐다.In addition, such a conventional double-sided mirror may not be able to perform the function of the double-sided mirror by making the double-sided mirror by using an adhesive, as well as being unable to perform the function of the double-sided mirror, because it is made of glass, it was inconvenient to carry due to damage or weight.
또한, 두 개의 일면경을 만들어 이를 접착제를 이용하여 결합시켜 양면 거울을 만들므로 제조공정이 복잡할 뿐만아니라, 재질이 유리이므로 다양한 디자인에도 한계가 따르는 단점이 있었다.In addition, since two mirrors are made by combining two mirrors using an adhesive to make a double-sided mirror, not only the manufacturing process is complicated but also the material is glass, which has limitations in various designs.

Vacuum coating is performed on both surfaces to form a reflective coating surface (step 31), to wash the product on which the reflective coating surface is formed (step 32), and to perform hard coating after the cleaning (step 33).
이러한 본 발명을 도 3 및 도 4와 함께 보다 상세히 살펴본다.This invention will be described in more detail with reference to FIGS. 3 and 4.
먼저, 거울 금형 코어 형상을 가공하기 위한 선반 가공을 하고(단계21), 선반 가공을 마치고 나면, 열처리를 하여 형상 가공된 거울 금형 코어의 강도를 증가시킨다(단계22). 열처리가 마쳐지면 거울 금형 코어를 0.03mm 크기의 세륨옥사이드로 1차 연삭을 한 후(단계23), 보다 세밀한 0.01mm 크기의 세륨옥사이드로 2차 연삭을 한다(단계24). 상기 연삭공정에서 세륨옥사이드가 0.03mm 이상의 크기인 경우 그 입자가 커서 효과적인 연삭이 이루어질 수 없으며, 마찬가지로 0.01mm 이하에서는 그 입자가 너무 작아 연삭의 효과를 거의 가질 수 없게 된다. 따라서 먼저 보다 조밀한 0.03mm 크기의 세륨옥사이드로 1차 연삭을 한 후, 연삭의 효과를 높이기 위하여 보다 세밀한 0.01mm 크기의 세륨옥사이드로 2차 연삭을 한다.First, the lathe processing for processing the mirror mold core shape is performed (step 21). After the lathe processing is finished, the heat treatment is performed to increase the strength of the shaped mirror mold core (step 22). After the heat treatment, the mirror mold core is first ground with 0.03 mm of cerium oxide (step 23), and then secondly ground with more fine 0.01 mm of cerium oxide (step 24). In the grinding process, when the cerium oxide is 0.03 mm or more in size, the particles are large and thus effective grinding cannot be achieved. Similarly, at 0.01 mm or less, the particles are too small to have the effect of grinding. Therefore, first grinding with a denser cerium oxide of 0.03mm in size, and then second grinding with a finer 0.01mm in size of cerium oxide in order to increase the effect of grinding.
상기 연삭공정 완료 후, 0.003mm 크기의 산화알루미나로 1차 폴리싱을 한 후(단계25), 0.001mm 크기의 산화알루미나로 2차 폴리싱을 한다(단계26). 상기 폴리싱공정에서도 산화알루미나의 크기가 0.003mm 이상인 경우, 그 입자가 커서 효과적인 폴리싱이 이루어질 수 없으며, 마찬가지로 0.001mm 이하인 경우 그 입자가 너무 작아 폴리싱의 효과를 거의 나타낼 수 없게 된다. 따라서 먼저 보다 조밀한 003mm 크기의 산화알루미나로 1차 폴리싱을 한 후, 폴리싱의 효과를 높이기 위하여 보다 세밀한 0.001mm 크기의 산화알루미나로 2차 폴리싱을 한다. 2차 폴리싱이 완료되면 폴리싱된 형상을 세정하고(단계27), 세정 공정이 마쳐지면, 금형을 조립한다(단계28). 상기 조립된 금형에 액상의 플라스틱을 주입시켜 사출함으로써 소정의 플라스틱 사출물을 얻는다(단계29).After completion of the grinding process, primary polishing is performed with alumina oxide having a size of 0.003 mm (step 25), and secondary polishing is performed with alumina oxide having a size of 0.001 mm (step 26). In the polishing process, when the size of the alumina oxide is 0.003 mm or more, the particles are large and thus effective polishing cannot be achieved. Similarly, when the size of the alumina oxide is 0.001 mm or less, the particles are too small to show the effect of polishing. Therefore, the first polishing is performed with a denser 003mm alumina oxide, and then the second polishing is performed with a finer 0.001mm alumina oxide in order to enhance the polishing effect. When the secondary polishing is completed, the polished shape is cleaned (step 27), and when the cleaning process is completed, the mold is assembled (step 28). A predetermined plastic injection molded product is obtained by injecting and injecting liquid plastic into the assembled mold (step 29).
상기 금형 기술에 대해 다시 한 번 살펴보면, 표면이 고경면 처리된 코어를 금형틀(Mold Base)에 삽입하고, 여기에 인젝션 머신을 통해 액상의 플라스틱을 주입하여 플라스틱 사출물을 얻는 것이며, 상기 코어의 경면 처리는 Rmax 0.02μm 이하로 가공표면을 유지하여야만 물체의 선명함을 확보할 수 있다.Looking at the mold technology again, the surface is a high-mirror-cored core is inserted into a mold base (Mold Base), the liquid plastic is injected through the injection machine to obtain a plastic injection molding, the mirror surface treatment of the core The sharpness of the object can be ensured only if the machining surface is maintained below Rmax 0.02μm.
그리고 상기 플라스틱 사출물은 사출시 금형틀의 형태에 따라 양면이 평면과 볼록면, 평면과 오목면, 볼록면과 오목면 등으로 사출될 수 있으며, 원형, 사각형, 별 모양등 다양한 형태로 얻어질 수 있다.In addition, the plastic injection molding may be injected into a flat and convex surface, a flat and concave surface, a convex surface and a concave surface, etc., depending on the shape of the mold during injection, and may be obtained in various shapes such as a circle, a square, and a star have.
상기 사출된 플라스틱은 1차 세정된 후(단계30), 플라스틱 사출물을 거울로 만들기 위해 진공로 내에 전압을 주어 알루미늄(Al)을 녹여 진공로에 설치된 제품에 코팅을 행하는 일반적인 진공코팅방법에 의하여 반사물질을 세정된 제품의 양면에 코팅한다(단계31). 이와 같이 하여 플라스틱 사출물의 양면에 반사코팅면이 만들어진 제품을 세정한 후(단계32), 다시 반사코팅면이 만들어진 플라스틱 사출물의 양면에 하드 코팅(Deeping)을 행하여 경면에 흠이나 기스가 나는 것을 방지한다(단계33).상기 하드코팅은 종래의 하드코팅방법을 사용하였으며, 일반적인 하드코팅방법은 아크릴계 수지를 코팅액으로 주로 사용하며, 경화방법에 따라서 IR계 와 UV계로 구분된다. 상기 IR계 하드코팅방법은 적외선 방식으로 많은 양을 경화할 수는 있으나 시간이 오래 걸리는 단점이 있으며, 반면 상기 UV계 하드코팅은 자외선 방식으로 한개씩 경화하여야 하나 경화시간이 매우 짧다는 이점이 있다.본 발명에서는 제품의 특성상 시간이 오래 걸리는 경화방법은 진공코팅시킨 반사 코팅막이 탈락될 우려가 있으므로, 아크릴수지 코팅액을 사용하여 UV계 하드코팅방법을 수행하였다. 또한 본 발명에서 하드코팅은 일반적인 디핑(Deeping)방식으로, 플라스틱 안경렌즈 하드코팅 방식을 사용하였다.The injected plastic is first cleaned (step 30), and then reflected by a general vacuum coating method in which a voltage is applied in a vacuum furnace to make the plastic injection molding mirror and melts aluminum (Al) to coat a product installed in the vacuum furnace. The material is coated on both sides of the cleaned product (step 31). In this way, after washing the product on which the reflective coated surface is formed on both sides of the plastic injection molding (step 32), hard coating (Deeping) on both sides of the plastic injection molded product on which the reflective coating surface is made again to prevent scratches or stains on the mirror surface. The hard coating method uses a conventional hard coating method, and a general hard coating method mainly uses an acrylic resin as a coating liquid, and is classified into an IR system and a UV system according to a curing method. The IR-based hard coating method has a disadvantage that it takes a long time to cure a large amount by the infrared method, while the UV-based hard coating has to be cured one by one in the ultraviolet method, but the curing time is very short. In the present invention, the curing method that takes a long time due to the characteristics of the product may drop off the vacuum-coated reflective coating, so that the UV-based hard coating method was performed using an acrylic resin coating solution. In addition, in the present invention, the hard coating is a general dipping (Deeping) method, a plastic eyeglass lens hard coating method was used.
상기의 과정을 거치면 도 3과 같은 플라스틱 양면 거울이 만들어지는 것이며, 도 3에는 사출된 플라스틱(11)의 양면을 평면으로만 도시한 것이다.Through the above process is to create a plastic double-sided mirror as shown in Figure 3, Figure 3 shows only the both sides of the injected plastic 11 in a plane.
한편, 상기에서는 단계(31-33)를 거쳐 플라스틱 사출물의 양면에 진공코팅과 하드코팅을 행하는 것으로 설명하였으나, 플라스틱 사출물의 일측면에 상기 단계(31-33)를 거쳐 용융 알루미늄(Al)을 진공코팅하여 반사코팅면을 형성하고, 하드 코팅을 행한 후, 다시 단계(31-33)을 거쳐 플라스틱 사출물의 타측면에 용융 알루미늄(Al)을 진공코팅하여 반사코팅면을 형성하고, 하드 코팅을 행하여도 된다.따라서 본 발명의 또다른 실시예에 따른 플라스틱 양면 거울의 제조방법은 거울 금형 코어의 형상을 가공하여 가공된 형상을 열처리한 후, 열처리된 형상을 세륨옥사이드로 연삭하는 제 1 과정을 수행하고(단계21-24), 상기 연삭된 거울 금형 코어를 산화알루미나로 폴리싱하는 제 2 과정을 수행하고(단계25-26), 상기 제 2 과정 수행후에 세정 및 금형을 조립한 후 상기 조립된 금형에 액상의 플라스틱을 주입하여 사출한 후, 세정하는 제 3 과정을 수행하고(단계27-30), 상기 플라스틱 사출물의 일측면에 반사물질 코팅과 하드 코팅을 행하는 제 4 과정을 수행하고(단계31-33), 상기 플라스틱 사출물의 타측면에 반사물질 코팅과 하드 코팅을 행하는 제 5 과정(단계31-33)을 포함하여 이루어짐을 특징으로 한다.On the other hand, in the above it was described as performing the vacuum coating and hard coating on both sides of the plastic injection molding through the step (31-33), but vacuum the molten aluminum (Al) through the step (31-33) on one side of the plastic injection molding After coating to form a reflective coating surface, and after performing a hard coating, through the step (31-33) again to form a reflective coating surface by vacuum coating molten aluminum (Al) on the other side of the plastic injection molding, and by hard coating Accordingly, in the method of manufacturing a plastic double-sided mirror according to another embodiment of the present invention, after processing the shape of the mirror mold core and heat-treating the processed shape, the first process of grinding the heat-treated shape with cerium oxide is performed. Performing a second process of polishing the ground mirror mold core with alumina oxide (steps 25-26), followed by cleaning and assembling the mold after performing the second process. After injecting a liquid plastic into the assembled mold and injecting the liquid, a third process of cleaning is performed (step 27-30), and a fourth process of coating the reflective material and hard coating on one side of the plastic injection molding is performed. (Step 31-33), and the fifth step (step 31-33) of performing a reflective coating and hard coating on the other side of the plastic injection molding.
상기의 단계(21-33)를 모두 수행하면 플라스틱 양면 거울은 완성되는 것이지만 이러한 플라스틱 양면 거울의 미감을 위해 조립단계(34)를 더 수행하여 다양한 형태로 제품을 조립할 수 있다.한편, 거울의 외경이 커질 경우 구면수차로 인한 왜곡으로 인해 물체가 둥글게 보이는데, 이를 보정하기 위해 본 발명에서는 도 4에 단계(21)의 수치 제어 선반으로 비구면 가공 후 단계(22)에서 단계(34)를 거쳐 비구면 처리하여 물체의 확대, 축소가 가능하게 하며, 물체가 왜곡없이 비춰지도록 할 수 있으며, 비구면 처리는 볼록경이나 오목경에만 행하면 된다.If all the above steps 21-33 are completed, the plastic double-sided mirror is completed, but for the aesthetics of the plastic double-sided mirror, the assembly step 34 can be further performed to assemble the product in various forms. In this case, the object looks round due to distortion due to spherical aberration. In order to correct this problem, in the present invention, the aspherical surface treatment is performed through step 34 in step 22 after aspheric processing with the numerical control lathe of step 21 in FIG. The object can be enlarged or reduced, the object can be projected without distortion, and the aspherical surface treatment needs to be performed only on convex or concave mirrors.
이상에서 살펴본 바와 같이 본 발명에 따른 양면 거울은 재질을 플라스틱을 이용함으로써 플라스틱의 견고성과 경량성에 따라 휴대가 용이한 거울에서 부터 아이들의 장난감 분야까지 다양하게 응용될 수 있으며, 다양한 디자인이 용이함으로심미성을 지닌 다양한 제품으로의 응용이 가능한 장점이 있다.As described above, the double-sided mirror according to the present invention can be applied to a variety of applications from the mirror to the children's toys, easy to carry according to the rigidity and light weight of the plastic by using a plastic material, various designs are easy There is an advantage that can be applied to various products with.
또한, 반사체의 표면 코팅으로 빛이 굴곡되지 않고, 비구면 처리를 통하여 왜곡없는 정확한 모습으로 비춰질 수 있으며, 양면이 평면과 오목, 오목면과 볼록, 볼록면과 평면으로 서로 조합되어 하나의 제품을 이루므로 메이크업시 세부 화장과 필요한 부분만을 비춰서 화장할 수 있는 부분 화장을 가능하게 해준다.In addition, the surface coating of the reflector does not bend the light, and aspheric surface treatment can be reflected in the correct appearance without distortion, and both sides are combined with each other in a plane and concave, concave and convex, convex and plane to form a single product Therefore, it makes possible to make up the part that can be done by shining only the necessary part and make-up at the time of make-up.
또한, 플라스틱 사출물의 양면에 동시에 진공코팅방법에 의하여 반사코팅면을 형성하고 하드코팅을 순차적으로 행하여 양면 거울을 얻을 수 있으므로 종래에 비해 제조공정이 단순해지는 잇점이 있으며, 거울의 크기가 큰 경우의 볼록면이나 오목면의 경우에는 표면을 비구면 처리함으로써 물체의 왜곡을 방지할 수 있게 된다.In addition, since the reflective coating surface is formed on both sides of the plastic injection molding at the same time by the vacuum coating method and the hard coating is sequentially performed, the double-sided mirror can be obtained. In the case of a convex surface or a concave surface, aspheric surface treatment can prevent distortion of an object.
