Abstract
본 고안은 다기능 휴대폰에서 발생되는 전자파를 차폐하여 사용자가 전자파에 노출되지 않도록 하는 휴대용 전자파 차폐 필름 케이스에 관한 고안이다.The present invention is to devise a portable electromagnetic shielding film case for shielding the electromagnetic waves generated in the multi-function mobile phone so that the user is not exposed to electromagnetic waves.
지금까지는 일반적으로 사용되는 휴대폰용 필름 케이스는 사용하고 있어나, 전자파 차폐용 케이스는 없었다. 일부에서는 부직포와 같은 천에 금속 분말을 첨가하여 제작된 타 용도의 제품을 존재하고 있었으나, 휴대폰용으로 사용하기에는 적절하지 않았으며, 전자파 차폐효과를 위한 제품이 아님으로 인한 문제점이 있었다. 따라서 본 고안에서는 아크릴계 점착제에 전도성 금속 분말 또는 전도성 고분자 물질을 첨가하여 폴리에틸렌 필름, 폴리프로 필름, 폴리 비닐 클로라이드 필름, 폴리에틸렌 테레프탈레이트 필름, 등과 같은 종류의 열가소성 필름에 도포하여 점착 필름을 만든 후, 점착 표면에 보호 필름으로 보호하여 다기능 휴대 폰에서 나오는 전자파를 차폐하여 폰 사용자가 전자파에 노출되지 않도록 하기위한 휴대폰용 전자파 차폐 필름 케이스에 대한 고안이다.Until now, although the film case for mobile phones generally used is used, there is no electromagnetic shielding case. In some cases, there was a product for other uses made by adding metal powder to a cloth such as a nonwoven fabric, but it was not suitable for use for a mobile phone, and there was a problem due to not being a product for electromagnetic shielding effect. Therefore, in the present invention, by adding a conductive metal powder or a conductive polymer material to the acrylic pressure-sensitive adhesive to apply to a thermoplastic film of the same kind, such as polyethylene film, polyprop film, polyvinyl chloride film, polyethylene terephthalate film, etc. It is designed to protect the electromagnetic wave from the multi-function mobile phone by protecting the surface with a protective film to prevent the phone user from being exposed to electromagnetic waves.
Description
본 고안은 휴대용 폰에 발생되는 전자파를 차폐하는 휴대폰 케이스에 대한 것으로 다시 말하면, 전도성 금속 분말이나, 전도성 고분자 물질을 첨가한 아크릴계 점착제가 열가소성 필름에 도포된 점착 필름을 다기능 휴대폰의 케이스에 점착함으로 휴대폰에서 발생되는 전자파를 차폐하는 휴대용 폰 케이스에 관한 것이다.The present invention relates to a mobile phone case that shields electromagnetic waves generated in a mobile phone. In other words, an acrylic pressure-sensitive adhesive containing conductive metal powder or a conductive polymer material is applied to a case of a multifunctional mobile phone by applying an adhesive film coated on a thermoplastic film to a case of a multifunctional mobile phone. It relates to a portable phone case shielding electromagnetic waves generated by.
지금까지는 전자파 차폐용인 아닌 일반용의 휴대폰용 필름 케이스가 있었으나, 전자파의 차폐와는 거리가 있었으며, 부직포 등에 금속 분말을 분산 첨가하여 제작한 필름 케이스가 있었으나, 이 또한 전자파의 차폐 기능을 하지 못하였다. 따라서 다기능 휴대폰에서 발생하는 전자파를 차폐하여 사용자가 전자파에 노출되지 않도록 막아주는 휴대폰 전자파 차폐 필름 케이스를 요구하게 되었다.Until now, there has been a film case for a general-purpose mobile phone which is not for electromagnetic wave shielding, but there is a distance from the shielding of electromagnetic waves, and there was a film case made by dispersing and adding metal powder to a nonwoven fabric, but this also did not function as a shielding electromagnetic wave. Therefore, there is a need for a mobile phone electromagnetic shielding film case that shields the electromagnetic waves generated from the multi-function mobile phone to prevent the user from being exposed to electromagnetic waves.
따라서 본 고안은 상기의 문제점들 해결하기 위하여 점착제에 전자파 차폐 금속류로서, 구리 분말, 은 분말, 탄소 나노 튜버 분말 등의 전기 전도가 양호한 금속 종류의 분말을 첨가 혼입하거나, 금속류 대신 전기 전도가 양호한 폴리싸이오펜 종류의 고분자 물질을 첨가 혼입하여 제작한 점착제를 열가소성 필름에 도포하고 제작된 전자파 차폐 점착 필름을 휴대폰용 케이스의 필요부에 부착하여 전자파 차폐의 기능을 제공하는데 그 목적이 있다.Therefore, in order to solve the above problems, the present invention adds and mixes a metal-type powder having good electrical conductivity such as copper powder, silver powder, carbon nanotube powder, or the like as an electromagnetic shielding metal to the pressure-sensitive adhesive, or a poly having good electrical conductivity instead of metals. The purpose of the present invention is to provide a function of electromagnetic shielding by applying a pressure-sensitive adhesive prepared by adding and mixing a thiophene-type polymer material to a thermoplastic film and attaching the produced electromagnetic shielding adhesive film to a necessary part of a case for a mobile phone.
