Description

[Detailed Description of the Invention] The present invention relates to a tape for shielding static electricity, electromagnetic waves, etc. that can protect the attached part from static electricity, electromagnetic waves, etc. by pasting the tape.

Many electronic devices and other devices that are currently widely used are adversely affected by static electricity. Furthermore, with the remarkable development of the electronics industry, a new pollution problem called electromagnetic pollution has arisen. What is this electromagnetic pollution?
For example, when electromagnetic waves generated by computers and related equipment directly hit the core of other computers, etc., the directly hit computers, etc., malfunction. This refers to industrial pollution, which is in contrast to the so-called electronics revolution, and will become more and more common in the future. This is expected to increase.

Therefore, if a tape capable of shielding not only static electricity but also electromagnetic waves and magnetic lines of force were developed, it would be extremely useful.

The present invention was developed against the background of the above-mentioned circumstances, with the purpose of providing a tape that can shield and protect a desired area from static electricity, electromagnetic waves, lines of magnetic force, etc. by attaching it to the desired area. The structure is characterized in that a conductive fiber layer is laminated on one side of a tape base material, and an adhesive is applied to the other side of the tape base material or the surface of the conductive fiber layer. It is.

Next, embodiments of the present invention will be described with reference to the drawings.

In FIG. 1, a conductive fiber layer 3 made of a nonwoven fabric made of conductive fibers is laminated on one side of a tape base material 1 made of vinyl chloride or other appropriate material via an adhesive layer 2. 5 is an enlarged cross-sectional view of an example of the tape of the present invention, which is formed by applying an adhesive 4 to the surface of the adhesive 4. In the figure, 5 is a release paper placed on the adhesive 4.

In FIG. 2, a conductive fiber layer 3 made of a nonwoven fabric made of conductive fibers is laminated on one side of a tape base material 1 via an adhesive layer 2, and a cover film 6 is attached to the surface of the conductive fiber layer 3. FIG. 2 is an enlarged cross-sectional view of another example of the present invention in which an adhesive 4 is applied to the other surface of the tape base material 1.

Moreover, in FIG. 3, in place of the cover film 6 of the tape shown in FIG. 2, the surface of the conductive fiber layer 3 is covered with approximately half of the fiber layer 3, and the surface of the fibers in the uncovered portion is covered. FIG. 7 is an enlarged cross-sectional view of another example of the present invention in which a half-cover film 7 is attached so that the half-cover film 7 is exposed.

In FIGS. 2 and 3, the same reference numerals as in FIG. 1 indicate the same members.

Therefore, the tape for shielding static electricity, electromagnetic waves, etc. of the present invention constructed as described above is applied by peeling the release paper 5 from the adhesive 4 and applying the adhesive to the part of the article that should be protected from static electricity, electromagnetic waves, etc. When the agent 4 side is attached, the conductive fiber layer 3 absorbs or eliminates static electricity, electromagnetic waves, and lines of magnetic force, and shields them, preventing them from having an adverse effect on the article, etc., and protecting the article, etc. from static electricity, etc. You can.

In particular, in the case of the tape shown in Figure 3, about half of the surface of the conductive fiber layer 3 is exposed, so the conductive fiber layer 3 exhibits a static eliminating and neutralizing effect and shields static electricity. extremely effective in protecting

It has been confirmed through experiments that each of the above tapes can completely shield against static electricity, and can weaken electromagnetic waves and lines of magnetic force.

The present invention is as described above, and includes static electricity,
A tape for shielding electromagnetic waves, etc. is made by laminating a conductive fiber layer on one side of a tape base material, and applying an adhesive to the other side of the tape base material or the surface of the conductive fiber layer. If this is attached to a part of an article that should be protected from static electricity or electromagnetic waves, the conductive fiber layer will shield the electromagnetic waves or static electricity, preventing them from reaching the part to be protected, or preventing them from reaching the part to be protected. Since it weakens the force caused by static electricity, etc., it is possible to prevent the article from being adversely affected by static electricity, etc., and its structure is simple, easy to manufacture, and can be provided at low cost.
