[Detailed Description of the Invention] Recently, the development of electronics has been remarkable, and micro devices are increasingly being used in many devices and electrical products, and advanced functions are being added to these devices. It contains an integrated circuit and generates microwave noise. Furthermore, as these electronic elements have become smaller and faster, the current they use has become weaker, and as a result, the intensity and frequency of noise entering from the outside has become close to that of signal radio waves. This causes malfunctions. Therefore, electronic devices are not allowed to emit noise to the outside or pick up noise from the outside, so microwaves are used for computers and other information devices surrounding them, office equipment, electronic medical equipment, automobiles, etc. Recently, there has been a particular demand for countermeasures against microwave noise in a wide range of fields. In response to this need, the present invention provides an inexpensive microwave device with excellent microwave effects.

The conventionally known method is as shown in Publication No. 44-8394, where the frequency of the irradiated microwave is approximately 9X109H.
In Z, the amount of backside reduction is 21.8 to 26.9 digihels, that is ■
(2) The effectiveness was less than 27% and it could not be put to practical use. In addition, the inventions of Japanese Patent Application Laid-open No. 47-83357 and Japanese Patent Publication No. 54-36441, both of which were invented by the author earlier, showed a reduction amount of 90 decihers or more when irradiated with microwaves of 1×1010 Hz, and the microwave ■■ effect was 90%. The above is excellent, but since the conductive material of this product uses silver powder, after the oil shock, the price of silver skyrocketed in reaction to the oil shock, jumping 2 to 3 times, resulting in an extremely high material cost. The cost has become significantly higher. No matter how effective the product is, if it is too expensive, the field of demand will be limited and it will become impractical, leading to a decline in demand. To improve this economical defect, the amount of expensive silver powder, which is a conductive material, should be reduced by 1/2.
If the weight can be reduced by 2, or 1/5, or even 1/10, it is inevitable that the cost will be reduced to 1/2, 1/5, or 1/10. However, since the surface area of the silver powder is contacted and connected by the rubber medium to form a conductive mechanism, and it is electrically a conductor similar to metal, it has excellent microwave effects. The conductive mechanism is 102 cm, 108 cm, 1015 cm,
The electrical resistance increases and it finally becomes an insulator, and microwave ■
■Function disappears. Therefore, the amount (weight) of silver must be reduced without destroying the conductive mechanism. As mentioned above, the conductive mechanism is constituted by the surface area of the silver particles contacting each other, so by reducing the amount of silver inside the constituent silver particles, which is not related to this surface area contact, it is possible to reduce the cost. This goal can be achieved by constructing a conductive mechanism using hollow, strong silver particles like soap bubbles as a medium and the same volume using rubber as a medium.
The weight can be reduced to 1/2, 1/5, or 1/10 if necessary. However, this is a technical idea, and in reality, hollow silver particles with grain sizes of 50 μm or less are not commercially available, so the present invention uses silver coating on the surface of hollow glass spheres with grain size of 44 μm or less. Add 150 to 250 parts (by weight) of the conductive particles to 100 parts (by weight) of methyl vinyl silicone rubber using a mixing roll, and then add an appropriate amount of crosslinking agent and a small amount of coloring agent to mix well and homogenize. After being dispersed in
It provides a superconducting rubber that is less than ■ cm and highly effective in microwave ■■.
