Description

다이캐스팅 금속재 전자기기 외장품의 표면처리방법{Surface treatment method of die-casting metal electronic devices exterior products.} Surface treatment method of die-casting metal electronic devices exterior products.

본 발명은 다이캐스팅 주조법으로 성형된 알루미늄 합금소재의 전자기기 외장품(휴대폰 케이스 등) 표면을 더욱 우수한 질감과 조도 및 칼라 처리가 가능한 새로운 표면처리법에 관한 것이다.The present invention relates to a new surface treatment method capable of more excellent texture, roughness and color treatment of the surface of the electronic device exterior article (mobile phone case, etc.) of the aluminum alloy material formed by die casting casting method.

통상 휴대폰 케이스 등과 같은 전자기기 외장품 중에는 다이캐스팅 주조법을 이용한 경량의 합금소재(주로 알루미늄 합금)로 성형 생산되는 경우가 많다.
In general, the electronic device such as a cell phone case is often produced by molding a lightweight alloy material (mainly aluminum alloy) using the die-casting casting method.

한편, 다이캐스팅 주조법으로 생산되는 휴대폰 금속재 케이스 표면에는 상품성 증대와 우수한 질감 구현 및 개질을 위해 일정한 두께의 금속박막을 형성시키는 표면처리공정이 실시되고 있는데, 종래에는 전도성을 이용한 전기 도금방법으로 이루어지고 있다.
Meanwhile, a surface treatment process for forming a metal thin film having a constant thickness is performed on the surface of a mobile phone metal case produced by die casting casting to increase the merchandise quality and to realize excellent texture and modification. .

그러나, 상기한 종래의 도금방법은 작업이 까다롭고 열악할 뿐 아니라 인체와 환경에 유해한 다량의 물질이 포함되고 배출됨으로 사용의 제한은 물론 환경에도 악영향이 불가피 할 뿐 아니라, 다양한 칼라의 연출이 사실상 어려워 부가성 높은 고품질의 상품생산에도 한계를 가질 수밖에 없는 상당한 문제점이 있었다.
However, the above-described conventional plating method is not only difficult and poor in operation, but also contains and discharges a large amount of substances harmful to the human body and the environment, which not only restricts use but also adversely affects the environment. Difficult to produce a high-quality product with high added value, there was a significant problem that has no limit.

즉, 종래의 전기도금에 의한 표면처리방법은, 금속에 뛰어난 특성과 양호한 밀착성을 가진 피막을 얻을 수 있는 장점은 있지만, That is, the conventional surface treatment method by electroplating has the advantage of obtaining a film having excellent properties and good adhesion to metal,

형상에 따라 도금하는 과정에서 얼룩이 생길 우려가 높아 불량 및 품질의 유지관리에 어려움이 따르고,Depending on the shape, there is a high possibility of staining during plating, which makes it difficult to maintain defects and quality.

특히, 도금에 사용되는 약액은 독성이 강하면서 환경에 유해한 CN을 포함하고 있어 폐수처리에 따른 추가적인 비용지출과 환경 유해성을 피할 수 없는 단점이 있을 뿐 아니라,In particular, the chemical solution used for plating contains CN, which is highly toxic and harmful to the environment, and thus, additional costs and environmental hazards due to wastewater treatment cannot be avoided.

작업환경과 조건이 극히 열악하여 작업자의 어려움은 물론 인력수급난과 원가비용이 크게 증가하는 문제점이 있다.
Due to the extremely poor working environment and conditions, there is a problem that the difficulty of workers, the supply and demand of manpower and the cost are greatly increased.

더군다나, 도금액에는 인체의 피부에 영향을 미치는 Ni(니켈)의 용출로 인해 휴대폰 케이스 사용자에게 알러지를 유발하는 경우가 많고, Ni(니켈) 성분이 제거된 경우에는 고품질의 도금피막의 형성이 어려워지는 등 상당한 문제점이 있다.
In addition, the plating solution often causes allergy to the user of the mobile phone case due to the elution of Ni (nickel) affecting the human skin, and when the Ni (nickel) component is removed, it is difficult to form a high quality plating film. Etc. There are considerable problems.

이의 대체 방법으로 일간에서는 화합물을 이용한 증착코팅방법도 간혹 시도되고 있기는 하나 이 증착방법은 작업 중 환경유해성분이 너무 과다하게 발생되는 문제로 인해 최근 환경오염에 큰 역점을 두는 현 국가시책에 비추어 극히 바람직하지 않은 방법으로 분류하고 있다.As an alternative method, the deposition coating method using a compound is sometimes attempted daily, but this deposition method is extremely difficult in view of the current national policy that puts a great emphasis on environmental pollution due to the excessive generation of environmentally harmful components during operation. It is classified as an undesirable method.

이에 본 발명에서는 금속재질(비철금속 합금) 휴대폰 케이스의 표면에 견고한 일정 두께의 금속 박막을 형성시킬 때, 보다 신속 간단하면서 균일한 박막형성이 가능하여 생산성과 품질향상에 크게 기여할 수 있을 뿐 아니라 특히 중요시되는 환경 및 인체유해성을 완전 배제할 수 있는 새로운 표면처리 방법을 제공함에 주안점을 두고 그 기술적 과제로서 완성한 것이다.Therefore, in the present invention, when forming a metal thin film of a certain thickness firmly on the surface of the metal material (non-ferrous metal alloy) mobile phone case, it is possible to form a thin film more quickly and simply, which can greatly contribute to productivity and quality improvement, especially important It is a technical task that focuses on providing a new surface treatment method that can completely eliminate environmental and human hazards.

위 기술적 과제를 달성하기 위한 본 발명은 휴대폰 금속재 케이스 표면에 크로메이트 또는 Non-크로메이트와 하도 프라이머를 도포하고, 증착용 하도 UV 또는 증착용 하도 열건조 도료를 도포한 다음 그 위에 스퍼터링(Sputtering), 아크 이온 플레이팅 (Arc Ion Plating) 중 선택된 하나의 진공증착법으로 금속박막을 형성하고, 그 위에는 중도 프라이머와, 상도 UV 또는 상도 열건조 도료를 도포해 마감처리는 하여서 된 것이다.In order to achieve the above technical problem, the present invention applies a chromate or non-chromate and a primer to a surface of a metal case of a mobile phone, and a sputtering, arc, or coating on the bottom coat UV or a coat bottom drying coat for deposition. The metal thin film is formed by vacuum evaporation method selected from one of the ion plating (Arc Ion Plating), and the finish is applied by applying a medium primer, top UV or top heat drying paint.

상기의 설명과 같은 본 발명은 다이캐스팅 금속재질의 휴대폰 케이스에 대한 박막 형성시 보다 적은 비용과 신속하고 간단한 방법으로 처리될 수 있을 뿐 아니라 금속박막의 탁월한 접착성으로 보다 우수한 표면경도, 내마모성, 내부식성을 얻을 수 있을 뿐 아니라 인체 및 환경에도 무해하여 이에 관한 제한성도 배제할 수 있는 등 그 기대되는 효과가 다대한 유용한 발명이다.As described above, the present invention can be processed at a lower cost and in a faster and simpler manner when forming a thin film on a cell phone case made of a die-casting metal, as well as excellent surface hardness, wear resistance, and corrosion resistance due to the excellent adhesion of the metal thin film. Not only can it be obtained, but also harmless to the human body and the environment, and the limitation thereof can be excluded.
