DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a carbon-based electromagnetic wave shielding material.

[0002]

2. Description of the Related Art Recently, devices that emit electromagnetic waves, such as televisions, microwave ovens, personal computers, mobile phones, game machines, etc., have increased. Because these devices are so convenient, those who use them will be exposed to this electromagnetic wave without their knowledge, so that, for example, when using a personal computer or watching TV, you may feel tired,
Physical and mental disorders such as tired eyes, heavy use of cell phones, brain tumors and cataracts, use of electronic carpets may cause pregnancy abnormalities, and cell phones may cause pacemaker malfunctions. Has become a major social problem.

Electromagnetic wave shielding is an important global issue because leaked electromagnetic waves cause various obstacles such as various communication failures, broadcasting equipment failures such as televisions, accidents in transport equipment such as airplanes, and malfunctions of automation equipment such as robots. But also. Of these,
Visibly, possible measures are being taken one after another, but with regard to electromagnetic interference to homes and individuals, causal relationships are not clear or measures are difficult, so measures that are always satisfactory are taken. It can not be said.

[0004]

The problem to be solved is that, among the above-mentioned conventional electromagnetic interferences, those for homes and individuals are not always clear because the causal relationship is not clear or countermeasures are difficult. Satisfactory measures have not been taken, the present invention has solved the above problems,
An object of the present invention is to provide a charcoal-based electromagnetic wave shielding material which is inexpensive, has no side effects, and is effective in purifying living environments such as activating animal and plant cells, purifying air, deodorizing, and promoting health.

[0005]

Means for Solving the Problems As shown in FIGS. 1 and 2, the present invention integrates a carbon powder, a ceramic powder, and a paper, which have a high specific surface area, a high graphitization rate, a high density, and a good electrical conductivity. This is a charcoal-based electromagnetic wave shielding material obtained by wrapping a carbonized and ceramics-containing paper sheet 1 with a nonwoven fabric 2. ADVANTAGE OF THE INVENTION According to this invention, the electromagnetic wave which various electronic devices emit is shielded, and mind and body are protected from the obstacle by exposure to an electromagnetic wave. Furthermore, it removes moisture from the room where it is placed, eliminates unpleasant odors, activates cells of animals and plants, including the human body, purifies the surrounding air, purifies the living environment, and improves health. Moreover, it is inexpensive and has no side effects.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of a charcoal-based electromagnetic wave shielding material according to the present invention will be described with reference to FIGS. 1 and 2. Reference numeral 1 denotes a paper sheet containing charcoal and ceramics. It is integrated with paper (Charcoal powder: ceramics = 7 to 8: 3 to
2). The charcoal powder is manufactured from Ubamegashi from Wakayama Prefecture, has a high specific surface area, a high graphitization rate,
Dense and highly conductive. The ceramic powder may be of any type as long as it is porous, has adsorptive properties (hygroscopicity and odor absorbing properties), and has a catalytic function. Mixtures of the components are preferred.

The form of the carbon / ceramics-containing paper sheet 1 will be specifically described. Various forms are conceivable. For example, a mixture of charcoal powder and ceramic powder is sandwiched between two paper sheets. Compression molded, carbon powder and ceramic powder dispersed in paper slurry, passed through many pairs of rolls, compression molded into sheets, laminated and stitched, or any of the above two Or a combination of three. In FIG. 1, 1a is a paper in which charcoal powder and ceramic powder are dispersed, and in FIG. 2, 1b is the paper 1a, 1b.
The mixture 2 of the charcoal powder and the ceramic powder sandwiched between a is a non-woven fabric with good air permeability that wraps the carbon / ceramics-containing paper sheet 1.

[0008] To explain the operation, the electromagnetic wave shielding material of the present invention is a microwave oven, a television, a word processor, a personal computer,
It is only necessary to place it near the part that emits electromagnetic waves of game machines, mobile phones, electric carpets, for example, put it on the back side of the above equipment, lay it below, or in the case of a microwave oven,
It may be attached to the lower surface of the internal turntable. In the case of a mobile phone, it is preferable to cover the side of the portion that emits the electromagnetic wave to the ear and the side to the pacemaker with the electromagnetic wave shielding material of the present invention.

[0009] By doing so, the carbon powder contained in the electromagnetic wave shielding material, which has a high graphitization rate, and is dense and has high conductivity, shields the electromagnetic waves emitted from the above-mentioned equipment by using a personal computer or a television. To prevent body fatigue, eye fatigue, brain tumors and cataracts caused by heavy use of mobile phones, abnormal pregnancy due to the use of electronic carpet, etc., and malfunction of pacemakers caused by mobile phones. Thus, the body and mind can be protected from obstacles caused by exposure to electromagnetic waves.

[0010] Further, the carbon powder contained in the electromagnetic wave shielding material is porous, has a large specific surface area, is rich in adsorptivity, and is excellent in adsorptivity. In addition to adsorbing odors, there are countless microorganisms in the pores, which have the deodorizing effect of decomposing odorous substances and replacing them with odorless substances. Moreover, charcoal powder contains a large amount of active negative electrons, and has a strong effect of supplying electrons to the surroundings (reducing action), activating cells of animals and plants, including the human body, and ionizing action. It purifies the air and gives the surrounding people, animals and plants a peaceful mood as if they were bathing in the forest. Ceramic powder has almost the same effect as charcoal powder, and when combined with charcoal powder,
Its action increases.

[0011]

[Effects of the Invention] Since the present invention is configured as described above, it shields electromagnetic waves emitted from various electronic devices and protects mind and body from obstacles caused by exposure to electromagnetic waves. Furthermore, it removes moisture from the room where it is placed, eliminates unpleasant odors, activates cells of animals and plants, including the human body, purifies the surrounding air, purifies the living environment, and improves health. Moreover, it is inexpensive and has no side effects.
