Description

Electromagnetic wave isolation device

The present invention relates to an isolation device, and more particularly to an electromagnetic wave isolation structure that can effectively block electromagnetic waves.

In the daily life, because of the use of electronic and electrical products, the environment is filled with electromagnetic waves. Although there is no exact research report to confirm the harm of electromagnetic waves to human body, according to 1983, the University of North Carolina - Savitz et al Study: Regular exposure to a magnetic field of 60 Hz, using a baby under the electric blanket during pregnancy, compared with the uninhibited, the cancer attack rate is 1.3 times higher, and the incidence of blood cancer brain tumor is 2.5 times higher. In 1987, Savitz et al. of the University of North Carolina pointed out that the research on radio broadcasting and radar operators has increased the relative risk of blood cancer.

In 2000, according to the April 5th report of the United Daily News, the British Consumers Association's Whih magazine warned that when using a mobile phone to evade the handset, the brain receives three times more electromagnetic waves than using a mobile phone. Indeed, in some cases, excessive electromagnetic waves can cause uncomfortable feelings that can cause multiple lesions. The phenomenon is especially obvious when using mobile phones, and some scholars believe that the harm of electromagnetic waves to the human body does exist, and the degree of harm will deepen as the contact time accumulates.

However, in addition to mobile phones, there are more obvious electromagnetic waves generated in daily life. Generally, electronic products such as computers, televisions, and even electric fans will have electromagnetic waves. Traditional devices for personalizing electromagnetic waves are targeted at actions. The anti-electromagnetic wave patch is designed in the form of the use of the telephone, and the anti-electromagnetic wave patch mainly forms an electromagnetic wave by the conductive rubber material or the conductive metal sheet, but the cost of the conductive rubber is high. This makes it unsuitable for the production of larger patches, and because the texture of the conductive rubber is relatively hard, when used in a mobile phone, the rubber material or the metal piece is not ventilated, so that the volume is reduced. In addition, the user may feel uncomfortable, so that the applicability is reduced.

Referring to FIG. 1, a product of electromagnetic wave shielding patch is currently available on the market, which is commonly used for attaching a door panel or a mobile phone for opening a microwave oven. The main body 1 has a stainless steel mesh bottom layer 12 and a fiber mesh bottom layer 11, both of which The adhesives are then superposed on each other and fixed, and are fixed to the stainless steel mesh bottom layer 12 to face the user's surface. However, since the shielding patch is superposed and fixed by the two mesh layers, the magnetic wave shielding effect is not good, and if the fixing method is improper, the two upper and lower mesh layers are easy to fall off, and in addition, the bonding process will increase the manufacturing cost, so Unable to achieve the desired results.

Accordingly, it is an object of the present invention to provide an electromagnetic wave isolation device comprising an isolation layer, a first substrate layer, and a second substrate layer.

The isolation layer has a first surface and a second surface, and the isolation layer is doped with a plurality of metal particles. The first substrate layer is attached to the first surface of the isolation layer. The second substrate layer is attached to the second surface of the isolation layer.

Therefore, the effect of the invention is that the isolation layer is doped with a plurality of metal particles to form a protective net blocking electromagnetic radiation, and the electromagnetic wave can be blocked, and the whole electromagnetic wave isolation device can be formed into various forms of anti-electromagnetic wave sheets, not only in the form of anti-electromagnetic wave sheets. The manufacturing cost of the whole electromagnetic wave isolating sheet can be reduced, and the applicability can be further increased. In addition, the first and second base layers can be printed with the characteristics of the pattern, so that the decorative effect can also be provided.

The details of the related patents and the technical contents of the present invention will be apparent from the following detailed description of the preferred embodiments of the accompanying drawings.

In actual production, the iron and milling metal are first ground into fine powder, mixed with liquid glue or paint, and then poured into a molding mold for refining, then sent to the oven for baking to become a solid semi-finished product. Then, the first and second base layers 32 and 33 are bonded together to complete the finished product. Of course, it is also possible to directly adhere the first and second substrate layers 32 and 33 by using the separator 31 which is still in the form of a liquid gel, so that the cost of the adhesive between the heterogeneous materials can be eliminated. As can be seen from Figure 3, in the manner of the first preferred embodiment, the metal particles 313 are thoroughly mixed and dispersed in the spacer layer 31.

It is worth mentioning that, according to the actual experiment of the applicant, it is confirmed that the thickness of the isolation layer is greater than 1mm, which has the effect of blocking electromagnetic waves. Of course, the actual implementation can also block the electromagnetic wave intensity as needed, and moderately increase its Thickness to make it work.
