본 발명은 VTR 이나 DVD 등의 전자제품의 디스플레이 표시부에 사용되는 전자제품 하프미러 제조방법 및 하프미러 코팅액에 관한 것으로써 더욱 상세하게는, 외부의 빛을 반사하여 거울의 효과를 가져오며, 금속재질의 표현으로 하프미러의 고급화와 심미감을 향상시키고 리모트콘트롤의 작동빔을 투과시킬 수 있는 하프미러 제조방법 및 하프미러 제조시 사용되는 코팅액에 관한 것이다.The present invention relates to an electronic half mirror manufacturing method and a half mirror coating liquid used in a display display unit of an electronic product such as a VTR or a DVD, and more particularly, reflects external light to bring an effect of a mirror, and a metal material. The present invention relates to a half mirror manufacturing method capable of improving the quality and aesthetics of a half mirror and transmitting a working beam of a remote control, and a coating liquid used in manufacturing the half mirror.

하프미러(half mirror)란 합성수지계열시트에 특수처리를 하여 거울과 같은 느낌을 주도록 제조된 제품으로서, 거울과 같은 반사적인 효과 외에 반투명의 투시감까지 함께 제공하는 것을 말한다. 일반적으로 합성수지계열에는 아크릴수지 또는 PC 수지가 많이 쓰인다.A half mirror is a product manufactured to give a mirror-like feeling by special treatment on a synthetic resin sheet, and also provides a translucent perspective in addition to the reflective effect such as a mirror. Generally, acrylic resins or PC resins are commonly used in synthetic resins.

이러한 하프미러(half mirror)는 일반적으로 아크릴수지 또는 PC 수지에 양면을 하드코팅한 후, 크롬이나 니켈, 알루미늄 등의 금속막을 증착하여 제품의 무게를 줄이고, 소비자의 심미감을 충족시키는 한편, 열전도율이 낮아 제품의 내부고장을 유발시키지 않는 장점이 있다. Such a half mirror is generally hard coated on both sides of an acrylic resin or a PC resin, and then a metal film such as chromium, nickel, or aluminum is deposited to reduce the weight of the product, satisfy the aesthetics of the consumer, and have high thermal conductivity. Low, there is an advantage that does not cause the internal failure of the product.

그러나, 상기와 같이 금속재질을 표현하기 위한 금속막의 증착에 사용되는 크롬은 중금속 오염 등으로 인해 현재는 일반적으로 니켈이나 알루미늄으로 금속막을 형성하여 금속재질의 질감을 나타내고 있다. 그러나 니켈이나 알루미늄의 경우, 내구성이 낮아 수분이나 산화 및 부식에 의해 탈막되어 미러효과를 발생시키지 못하고 심미감을 현저히 떨어뜨려 제품 자체의 안정성에 문제점이 있었다.However, chromium used for the deposition of a metal film for expressing a metal material as described above generally shows the texture of the metal material by forming a metal film with nickel or aluminum due to heavy metal contamination. However, in the case of nickel or aluminum, due to its low durability, the film was removed by moisture, oxidation, and corrosion, so that the mirror effect was not generated, and the aesthetics were remarkably decreased, thereby causing stability of the product itself.

본 발명은 상기와 같은 문제점을 해결하기 위해 안출된 것으로, 종래와 같이 금속재질을 표현하기 위한 합성수지계열시트의 증착막 형성 후 별도의 코팅액을 이용한 코팅단계를 첨가함으로써 금속막의 탈막 및 산화 부식 등을 방지하여 심미감 있고 보다 안정적인 하프미러를 제공하는데 그 목적이 있다.The present invention has been made to solve the above problems, and after forming the deposition film of the synthetic resin series sheet to express the metal material as in the prior art to prevent the film removal and oxidative corrosion of the metal film by adding a coating step using a separate coating solution. The purpose is to provide an aesthetic and more stable half mirror.

상술한 기술적 과제를 달성하기 위하여, In order to achieve the above technical problem,

본 발명은 필름막이 양면에 씌어지고 양면이 하드코팅된 합성수지계열 시트의 일면에 금속의 증착막을 형성하는 금속의 증착막 형성단계(100);The present invention is a metal film deposition step forming step of forming a metal deposition film on one surface of the synthetic resin series sheet is coated on both sides and hard-coated both sides;

상기 금속증착막이 형성된 합성수지계열 시트를 별도의 장소에서 건조시키는 건조단계(300);  A drying step of drying the synthetic resin series sheet in which the metal deposition film is formed at a separate place (300);

상기 건조단계를 거친 합성수지계열 시트는 에칭을 통하여 증착막이 필요없는 부위의 증착막을 제거하는 에칭단계(400) 및 상기 에칭단계(400)를 거친 합성수지계열 시트에 N.C가공을 하는 C.N.C가공단계(500)로 이루어지는 일반적인 하프미러 제조방법에 있어서,The drying step of the synthetic resin series sheet is an etching step (400) for removing the deposition film of the portion that does not need a deposition film through etching and the CNC processing step 500 for NC processing on the synthetic resin series sheet through the etching step (400) In the general half mirror manufacturing method consisting of,

상기 증착막 형성단계(100)와 건조단계(300)사이에 금속의 증착막을 보호하 기 위한 코팅단계(200)를 제공하며, 상기 코팅단계(200)에 사용되는 코팅액은 기존 우레탄수지에 생산가교제로 사용되는 산촉매인 Amino alkanol ester가 첨가된 하프미러(half mirror) 코팅액을 제공한다.Provides a coating step 200 to protect the deposited film of the metal between the deposition film forming step 100 and the drying step 300, the coating liquid used in the coating step 200 as a production crosslinking agent to the existing urethane resin It provides a half mirror coating liquid to which the acid catalyst Amino alkanol ester used is added.

이하, 첨부된 도면을 통하여 본 발명에 따른 하프미러(half mirror)제조방법 및 하프미러(half mirror)에 사용되는 코팅액을 상세히 설명한다.Hereinafter, a method of manufacturing a half mirror and a coating liquid used for a half mirror according to the present invention will be described in detail with reference to the accompanying drawings.

도 1은 일반적으로 사용되는 하프미러 단면도이다1 is a cross-sectional view of a commonly used half mirror.

상기한 바와 같이 하프미러(half mirror)는 합성수지계열시트(10)에 특수처리를 하여 거울과 같은 느낌을 주도록 하기 위한 제품으로서, 거울과 같은 반사적인 효과외에 반투명의 투시감까지 함께 제공하는 것을 말하는데, 유리 시트가 아닌 합성수지계열시트가 쓰이는 이유는 제품의 무게가 가볍고 파손의 우려가 적기 때문이다. 합성수지계열 중 주로 아크릴수지 또는 PC 수지가 많이 쓰인다.As described above, the half mirror is a product for giving a synthetic-like treatment to the synthetic resin sheet 10 so as to give a mirror-like feeling. It is to provide a translucent perspective in addition to the reflective effect such as a mirror. The reason why synthetic resin sheets are used instead of glass sheets is that the weight of the product is light and there is little risk of breakage. Acrylic resin or PC resin is mainly used among synthetic resins.

상기한 합성수지계열시트(10) 양면에 하드코팅(20,30)을 하는데 이는 합성수지계열시트 즉 아크릴 소재 또는 PC 소재의 경도가 증가하고, 투과도가 증가하기 때문이다. 또한, 합성수지 자체를 보호함과 더불어 금속막의 증착(40)을 쉽게 하기 위한 것이다. 이러한 금속막의 증착(40)은 과거에 크롬이 많이 쓰였으나, 중금속 오염의 문제로 인해 니켈이나 알루미늄으로 금속의 재질감을 나타내는 것이 일반적인 추세이다. The hard coatings 20 and 30 are applied to both surfaces of the synthetic resin sheet 10 because the hardness of the synthetic resin sheet, that is, the acrylic material or the PC material increases, and the transmittance thereof increases. In addition, to protect the synthetic resin itself, and to facilitate the deposition of the metal film (40). In the deposition of the metal film 40, chromium was used a lot in the past, but due to the problem of heavy metal contamination, it is a general trend that the texture of the metal is represented by nickel or aluminum.

즉, 아크릴수지(10) 또는 PC 수지의 양면을 하드코팅(20,30)한 후, 금속의 재질감을 나타내기 위해 니켈이나 알루미늄으로 금속막을 증착(40)하여 고급스러운 이미지를 나타내었는데, 니켈이나 알루미늄은 그 자체가 산화 및 부식에 약하여 내구성이 약한 문제점이 있었던 것이다.That is, after hard coating (20, 30) of both sides of the acrylic resin (10) or PC resin, a metal film was deposited (40) with nickel or aluminum to show the texture of the metal, showing a luxurious image. Aluminum itself is weak in oxidation and corrosion had a problem of weak durability.

도 2는 본 발명에 따른 하프미러 제조방법이다.Figure 2 is a half mirror manufacturing method according to the present invention.

상기한 바와 같이 일반적으로 사용되어온 하프미러는 양면 하드코팅(20,30)된 합성수지계열시트(10)에 금속막을 증착(40)하여 사용되어 왔으나, 이러한 제품을 제조하는 단계에서 본 발명은 증착막 형성 단계(100)후 코팅단계(200)를 첨가한 모습을 나타낸다.Half mirrors, which have been generally used as described above, have been used by depositing a metal film 40 on a synthetic resin series sheet 10 having double-sided hard coatings 20 and 30, but in the step of manufacturing such a product, the present invention forms a deposited film. After the step 100 shows the appearance of the coating step 200 is added.

이하 각 단계 중 당업자에게 공지되어 사용되는, 필름막이 양면에 씌어지고 양면이 하드코팅된 합성수지계열 시트의 일면에 금속의 증착막을 형성하는 금속의 증착막 형성단계(100); 상기 금속증착막이 형성된 합성수지계열 시트를 별도의 장소에서 건조시키는 건조단계(300); 상기 건조단계를 거친 합성수지계열 시트는 에칭을 통하여 증착막이 필요없는 부위의 증착막을 제거하는 에칭단계(400) 및 상기 에칭단계(400)를 거친 합성수지계열 시트에 N.C가공을 하는 C.N.C가공단계(500)의 설명은 생략한다.Metal deposition film forming step 100 of forming a metal deposition film on one surface of the synthetic resin series sheet is coated on both sides and hard-coated on both sides, which is known and used by those skilled in the art of each step below; A drying step of drying the synthetic resin series sheet in which the metal deposition film is formed at a separate place (300); The drying step of the synthetic resin series sheet is an etching step (400) for removing the deposition film of the portion that does not need a deposition film through etching and the CNC processing step 500 for NC processing on the synthetic resin series sheet through the etching step (400) Will be omitted.

본 발명에 따른 코팅단계는 상기 증착막 형성단계(100)와 건조단계(300)사이에 금속의 증착막을 보호하기 위한 것으로써, 상기 코팅단계(200)에 사용되는 코팅액은 기존 우레탄수지에 생산가교제로 사용되는 산촉매인 Amino alkanol ester가 첨가된 하프미러(half mirror) 코팅액이다. The coating step according to the present invention is to protect the deposited film of the metal between the deposition film forming step 100 and the drying step 300, the coating liquid used in the coating step 200 as a production crosslinking agent in the existing urethane resin It is a half mirror coating liquid to which the acid catalyst Amino alkanol ester which is used is added.

코팅단계를 거치지 않은 기존의 하프미러의 경우 자동 산화가 일어나는데, 이는 연쇄반응으로 진행이 된다. 전체반응은 반복적으로 구성되고 각 단계마다 연쇄운반체라는 중간 생성물들이 발생하는 문제가 있다. 이러한 반응은 연쇄운반체들이 존재하는 한 계속 진행을 하게 되는데, 이는 자동 산화단계에서 연쇄 운반체는 홀전자를 갖고 있어 문제가 된다. 연쇄반응시 열을 받은 들뜬 분자, 전기적으로 중성인 자유라디칼이 금속촉매, 빛 등에 의해 반응을 시작하는데 본 발명에 따른 산촉매인 Amino alkanol ester를 첨가한 코팅액을 이용하여 코팅을 할 경우 연쇄 운반체를 차단하여 연쇄반응을 종결시킨다. 즉 대기중의 산소와 수분으로부터 금속막의 증착을 보호할 수 있게 되는 것이다.In the case of the conventional half mirror without a coating step, automatic oxidation occurs, which proceeds to a chain reaction. The overall reaction is repeated and there is a problem in that intermediate products, which are chain carriers, occur at each step. This reaction proceeds as long as there are chain carriers, which is a problem because the chain carrier has an electron in the automatic oxidation step. During the chain reaction, excited molecules heated by heat, electrically neutral free radicals start the reaction by metal catalysts, light, etc., and the chain carriers are blocked when the coating solution is added with the acid catalyst Amino alkanol ester according to the present invention. To terminate the chain reaction. That is, the deposition of the metal film can be protected from oxygen and moisture in the atmosphere.

본 발명에 따른 코팅단계에 사용되는 산촉매인 Amino alkanol ester를 첨가한 코팅액은 특수비닐성 아크릴 레진으로서 매우 높은 산가(Acid)를 지니고 있으며 다른 우레탄 도료에 비해 우레탄 반응 후에도 도막의 수축을 없애며, 금속증착막과도 부착력이 우수하다. 이는 금속산화물 등의 극성 고체면에는 극성의 레진이 부착력이 우수하고, 고분자 극성기, 분자구조가 유사한 것끼리는 서로 사용하고 부착력이 우수하기 때문이며, 높은 산가(Acid)는 금속표면의 부착력을 증가시켜 금속증착막의 변색 및 산화를 방지할 수 있게 되는 것이다.The coating solution to which the acid catalyst Amino alkanol ester used in the coating step according to the present invention is added is a special vinyl acryl resin and has a very high acid value. Excellent transient adhesion. This is because polar resins have excellent adhesion to polar solid surfaces such as metal oxides, and polymer polar groups and those with similar molecular structures are used with each other and have excellent adhesion.Acid increases the adhesion of metal to metal surfaces. Discoloration and oxidation of the deposited film can be prevented.

Amino alkanol ester는 산화방지용 2액형 도료로써 투명색상을 나타내며 도 막광택은 유광이다. 피도면은 알루미늄 증착막이며, 건조 두께는 7-10 ㎛이 적당하고, 코팅시의 도장방법으로는 에어 자동스프레이 방법이 바람직하다. 본 발명에 따른 코팅액의 경화제와 신나의 비율은 100:10 - 80:100 의 혼합비가 바람직하다. Amino alkanol ester is an anti-oxidant two-component paint that has a clear color and gloss. The surface to be coated is an aluminum vapor deposition film, and a dry thickness of 7-10 탆 is suitable, and an air automatic spray method is preferable as a coating method during coating. As for the ratio of the hardening | curing agent and thinner of the coating liquid which concerns on this invention, the mixing ratio of 100: 10-80: 100 is preferable.
