Description
본 발명은 플라스틱소재를 이용한 자동차용 룸미러(Room Mirror)와 그 제조방법, 더욱 상세하게는 폴리카보네이트(Polycabonate)또는 PMMA(Polymethy Metha Acrylate)등의 플라스틱소재로 룸미러를 제작하여 충격에 의한 파손시 파편의 발생을 방지함에 따라 파편에 의한 2차 사고를 미연에 방지할 수 있게한 자동차용 룸미러와, 그 제조방법에 관한 것이다.The present invention relates to an automobile room mirror using a plastic material and a manufacturing method thereof, more specifically, a room mirror made of a plastic material such as polycarbonate (Polycarbonate) or PMMA (polymethy methacrylate) And more particularly, to a room mirror for an automobile, which can prevent a secondary accident caused by debris as it prevents the generation of debris, and a manufacturing method thereof.
일반적으로, 자동차용 룸미러(10)의 소재를 유리재로 되고, 이 유리소재(1)를 도 1내지 도 2에서와 같이 소정형상으로 가공한 후 알루미늄재 또는 크롬재로된 반사 코팅막(2)과 보호막(3)을 순차적으로 형성하여 룸미러를 제조하였다.In general, the material of the automotive room mirror 10 is made of a glass material, and after the glass material 1 is processed into a predetermined shape as shown in Figs. 1 and 2, a reflection coating film 2 made of aluminum or chromium ) And a protective film 3 were sequentially formed to fabricate a room mirror.
상기 유리재로된 룸미러는 취성이 약하여 작은 충격에도 손쉽게 파손되었고, 이때 발생된 파손부위는 예리한 칼날형태로 되므로써 인체에 치명적인 손상을 가하는 하나의 요인이 됨으로써, 자동차 사고시 2차적인 사고를 유발하는 문제점이 있었다.The room mirror made of the glass material is fragile and easily broken even with a small impact. The damaged portion generated at this time is a sharp blade, which is one of the factors causing fatal damage to the human body. Thus, There was a problem.
특히, 자동차 사고의 대부부은 차체의 전면에서 발생하게 되어 룸미러에 의한 2차사고의 위험이 더욱더 가중되기도 하였다.Particularly, since the majority of the automobile accidents occurred at the front of the vehicle body, the risk of the second accident due to the room mirror was further increased.
그라한 위험 때문에 룸미러를 차내의 다른 위치에 설치하는 방법을 모색한다는 것은 차량의 후방시야에 막대한 지장을 주게되므로 결코 바람직한 의도라 할 수 없었다.It was never a good idea to look for a way to install a room mirror in a different location in the car because of the danger, because it would have a huge impact on the rear view of the vehicle.
위에서 열거한 바에 의하면 자동차용 룸미러는 차량의 안전운행에 없어서는 안될 필수적인 반면, 때로는 운전자 또는 탑승자에게 해를 가하는 ㅓ도구로 변하기도 하였다.As mentioned above, automotive room mirrors have become indispensable for the safe operation of the vehicle, but sometimes it has become a tool for harming the driver or occupant.
본 발명은 위와 같은 종래의 룸미러의 문제점을 해결하기 위해 안출한 것으로, 그 목적은 충격이나 충돌에 의해 변형이 가해질 때 그 변형을 흡수하여 굴신될 수 있게한 플라스틱 소재를 이용한 자동차용 룸미러를 제공하는 것이다.The object of the present invention is to provide a room mirror for a vehicle using a plastic material capable of absorbing deformation when deformed due to impact or collision, .
본 발명의 다른 목적은, 충격이나 충돌에 대한 내충격을 구비하여 파손이 방지되는 플라스틱소재를 이용한 자동차용 룸미러의 제조방법을 제공함에 있다.It is another object of the present invention to provide a method of manufacturing a room mirror for a vehicle using a plastic material which is resistant to impact and impact and is protected against breakage.
이러한 목적을 달성하기 위한 본 발명은, 폴리카보네이트 또는 PMMA등의 재료를 소정형상으로 제작하여 그 어느 일면에 반사막을 형성하고 이의 표면 및 그 반대측면에는 경도를 부여하면서 양측표면을 보호하는 하드막을 형성함에 따라, 룸미러에 충격이 가해질 경우 파손으로 인한 2차사고를 방지하여 운전자 및 탑승자를 보호하게 된 것 특징으로 한다.In order to achieve the above object, the present invention provides a method of manufacturing a semiconductor device, which comprises the steps of: forming a material such as polycarbonate or PMMA in a predetermined shape, forming a reflective film on one surface thereof and hardening the surface thereof, , It protects the driver and passengers by preventing the second accident caused by the breakage when an impact is applied to the room mirror.

이하 본 발명의 플라스틱 소재를 이용한 자동차용 룸미러와 그 제조방법을 첨부도면을 참조하여 설명하면 다음과 같다.DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an automobile room mirror using the plastic material of the present invention and a manufacturing method thereof will be described with reference to the accompanying drawings.
도 3은 본 발명의 실시예의 룸미러 제조공정을 나타낸 블럭도로서, 폴리카보네이트 또는 PMMA등의 내충격이 강한 플라스틱 소재의 원재료를 제습건조기에서 110℃~120℃의 분위기에서 120~210분 정도 가열,건조시켜 사출 성형기에 의해 룸미러(10)형상의 모재(11)를 사출성형한다.FIG. 3 is a block diagram showing a process of manufacturing a room mirror according to an embodiment of the present invention, in which a raw material of a plastic material having a high impact resistance such as polycarbonate or PMMA is heated in a dehumidifying drier in an atmosphere at 110 ° C. to 120 ° C. for 120 to 210 minutes, The base material 11 having the shape of the room mirror 10 is injection molded by an injection molding machine.
상기 폴리카보네이트와 PMMA의 내충격강도는 각각 60~85kg/cm,3~6.5kg/cm가 바람직하다.The impact strength of the polycarbonate and PMMA is preferably 60 to 85 kg / cm and 3 to 6.5 kg / cm, respectively.
상기 사출성형기를 통해 룸미러의 형상으로 사출성형된 모재는 중성세제 등으로 세척한다.The base material injection-molded in the shape of a room mirror through the injection molding machine is cleaned with a neutral detergent or the like.
세척제로는 살균작용을 겸하는 이소 프로필 알콜(iso propyi alcohol)이 적합하다.As a cleaning agent, isopropyl alcohol (iso propyi alcohol), which also acts as a sterilizing agent, is suitable.
세척이 완료된 모재는 알루미늄재를 가열.증발시키는 진공증착기의 증착실에서 3.0×10-4Torr의 분위기로 증착시켜 어느 일면에 반사막 코팅을 한후, 이 모재를 아크릴 계통의 코팅액 중에 침적 및 이탈되게 디핑방식 또는 스프레이 방식으로 코팅하여 양측표면에 하드막코팅을 한다.The washed base material was vapor-deposited in an evaporation chamber of a vacuum evaporator for heating and evaporating an aluminum material in an atmosphere of 3.0 × 10 -4 Torr to form a reflection film on one side of the substrate. The base material was immersed in an acrylic system coating liquid, Coating or spraying method to hard-coat the both surfaces.
상기 진공증착기 증착실 온도는 60~70℃종도가 바람직하다.The temperature of the vacuum evaporator deposition chamber is preferably 60 to 70 ° C.
하드막 코팅이 완료된 모재는 70℃정도의 온도하에서 약 10-30분정도 1차 건조를 한후 약 135℃정도의 고온에서 30~40분간 2차건조를하여 경화시킴에 따라, 유리와 동일 내지 유사한 반사율이 구비된 룸미러로 제작된다.After the hard film coating has been completed, the base material is first dried for about 10-30 minutes at a temperature of about 70 ° C, and secondarily dried at a high temperature of about 135 ° C for 30 to 40 minutes to cure the base material. And is made of a room mirror having a reflectance.
이때 하드막 코팅이 완료된 모재를 그 온도 및 시간을 번화시켜 1차건조로 경화를 완성할 수 있으나, 급격한 온도변화에 의해 발생될 수 있는 균열이나 색상변화 등의 이상현상을 방지하기 위해서 적어도 복수회의 건조가 바람직하다.In this case, it is possible to complete the curing with the primary drying by varying the temperature and the time of the hard film coated base material. However, in order to prevent abnormal phenomena such as cracks and color change which may be caused by the rapid temperature change, Drying is preferred.
한편, 모재에 하드막 코팅을 하게될 때 실리콘 계통의 코팅액을 사용하는 것도 가능하다.On the other hand, it is also possible to use a silicone-based coating liquid when the hard coating is applied to the base material.
상기한 공정에 의해 도 4에서와 같이 플라스틱 소재로 된 모재(11)의 일면에 반사막(12)이 형성되고 그 양측 표면에는 하드막(13)이 각각 형성되어 내구성과 내열성이 구비된 룸미러(10)를 얻을 수 있게 된다.4, a reflective film 12 is formed on one side of a base material 11 made of a plastic material and a hard film 13 is formed on both sides of the base film 11 to form a room mirror (not shown) having durability and heat resistance 10).
이와 같은 본 발명의 플라스틱 소재로 된 룸미러는 외형적으로나 기능적으로 볼 때 유리소재로 된 룸미러와 동일한 작용을 하게되며, 룸미러에 충격이 가해질 때 그 충격이 가해지는 만큼 굴신변형은 일어날지언정 파손이 방지되어 2차사고를 미연에 방지할 수 있는 효과가 있다.The room mirror made of the plastic material of the present invention has the same function as the room mirror made of a glass material when viewed from an external viewpoint or a functional viewpoint, and when the impact is applied to the room mirror, Breakage is prevented so that the second gear can be prevented in advance.
