It can be used to shield electromagnetic waves over a wide range of areas by manufacturing electromagnetic shielding materials, and it can protect the human body from harmful electromagnetic waves by making electromagnetic shielding materials in the form of accessories that can be worn on the body. It relates to a method for manufacturing an electromagnetic shielding material and an electromagnetic shielding material by the method.

현대인은 가정 및 공업용 전력의 사용시나 텔레비견 수상기 및 컴퓨터 모니터의 시청시에 발생되는 유해 전자파는 물론 각종 통신 및 계측장비의 운용시나 레이이저 가공, 엑스레이 촬영, 방사선등에서 발생되는 다량의 유해 전자파에 직접 노출되어 있다. 상기한 각종의 유해 전자파가 인체내에 누적되면 각종 질병을 유발시킬 염려가 있을 뿐만 아니라 암 및 불임증등의 치명적인 증상을 유발시키게 된다. 따라서, 유해 전자파로부터 인체를 충분히 보호해야 할 필요성이 절실히 요구되고 있다.Modern people are not only concerned with the harmful electromagnetic waves generated when using household and industrial electric power, watching television receivers and computer monitors, but also by using a large amount of harmful electromagnetic waves generated during the operation of various communication and measurement equipment, laser processing, X-ray imaging, and radiation. Exposed When the various harmful electromagnetic waves are accumulated in the human body, not only there is a fear of causing various diseases, but also fatal symptoms such as cancer and infertility. Therefore, there is an urgent need for a sufficient protection of the human body from harmful electromagnetic waves.

상기와 같은 유해전자파의 해악이 지적됨에 따라 생활주변에서 발생되는 각종 유해 전자파를 차폐시켜 인체를 유해 전자파로부터 보호하기 위한 연구가 활발히 진행되고 있는 바, 현재 유해 전자파의 차폐를 위한 수단이 가장 보편적으로 이루어지고 있는 분야는 텔레비젼 수상기 및 컴퓨터 모니터이다. 이는 화면의 전면에 보안경을 설치한 것이 통상적인 것이나, 이러한 보안경은 그 설치가 번거롭고 차폐효과가 대단히 미미한 점이 있다. 또한 텔레비젼 수상기나 컴퓨터 모니터의 경우 사실상 화면을 통해 방출되는 유해 전자파 못지 않게 본체 및 주변기기에서 발생되는 유해 전자파의 방출량이 많았는 바, 그 설치에 따른 유해 전자파 차폐의 효과가 부족하였다. 그리고 보안경의 사용범위가 텔레비젼 수상기 및 컴퓨터 모티터등 화면을 갖는 제품에만 국한적으로 사용할 수 밖에 없는 문제점이 있었다.As the harmful electromagnetic waves are pointed out above, researches are being actively conducted to protect the human body from harmful electromagnetic waves by shielding various harmful electromagnetic waves generated around living, and the means for shielding harmful electromagnetic waves is the most common. Areas of application are television receivers and computer monitors. It is common to install a protective goggles on the front of the screen, but these goggles are cumbersome to install and have a very small shielding effect.

In addition, there is a problem that the use range of the safety glasses can be used only for products having a screen such as a television receiver and a computer monitor.

종래의 보안경은 상기한 다수의 문제점이 있어 실질적인 활용이 폭넓게 이루어지지 않았으며, 보안경등의 수단외에는 유해 전자파의 차폐를 위한 별다른 수단이 없었던 바, 생활주변의 각종 유해 전자파로부터 인체를 완벽하게 보호해주고 아울러 더욱 광범위한 영역에 거쳐 이용할 수 있도록 한 전자파 차폐물질의 필요성이 절실하다.Conventional safety goggles have a number of problems described above did not have a wide range of practical applications, there was no means for shielding harmful electromagnetic waves other than means such as safety goggles, it protects the human body completely from various harmful electromagnetic waves around life In addition, there is an urgent need for electromagnetic shielding materials that can be used across a wider range of applications.

따라서, 본 발명의 목적은 전자파 차폐물질을 도색이나 인쇄를 할 수 있는 도료의 형태로 제조할 수 있도록 하여 광범위영역에 거쳐 전자파의 차폐에 사용할수 있도록 함은 물론 전자파 차폐물질을 안경테나 뱃지등의 소품형태로 제작하므로써 위소품을 인체에 착용하는 간단한 행위만으로 생활주변의 각종 유해 전자파로부터 인체를 효과적으로 보호해줄 수 있도록 된 전자파 차폐물질 제조방법 및 그 방법에 의한 전자파 차폐물질을 제공함에 그 목적이 있다.Accordingly, an object of the present invention is to be able to manufacture the electromagnetic shielding material in the form of a paint that can be painted or printed, so that it can be used for shielding electromagnetic waves over a wide range of areas, as well as the electromagnetic shielding material such as glasses frames or badges Its purpose is to provide an electromagnetic shielding material manufacturing method and an electromagnetic shielding material by the method that can effectively protect the human body from various harmful electromagnetic waves around the life by simply wearing a small item on the human body by making it in a small form. .
