[0002]

2. Description of the Related Art Conventionally, transparent electromagnetic wave shield materials,
As the sheet material using the conducting wire, for example, a conductive mesh in which a fiber such as polyester is knitted to have conductivity with a copper or nickel coating is used, and this is used as a transparent adhesive film on a transparent substrate. Also known is one fixed with an adhesive, and is used as a front plate for display members such as cathode ray tubes and plasma display panels.

[0003]

The conductive mesh described above is formed, for example, by weaving fibers such as polyester into a mesh and then forming a copper or nickel coating on the surface of the fibers using a technique such as sputtering or electroless plating. However, this is what gives conductivity. However, such a manufacturing method requires the work of weaving fibers such as polyester and the work of coating the fibers with copper or nickel, which is not preferable in terms of manufacturing efficiency.

Moreover, one sheet of transparent electromagnetic wave shielding material is produced by superposing the above-mentioned conductive mesh on the adhesive film and the transparent substrate and heating and pressing.
The number of manufacturing steps increases, and the processing time increases accordingly.

The purpose is to provide.

[0006]

To achieve the above object, according to the present invention, a pair of comb-shaped bodies in which a plurality of comb-shaped teeth are linearly arranged at a constant pitch can mesh with each other. An arraying device arranged opposite to each other is prepared, a conducting wire is arranged so as to cross a plurality of comb teeth of the both comb-shaped bodies, and in that state, the comb teeth of the both comb-shaped bodies are engaged with each other By moving the comb-shaped body of the above and positioning the comb-tooth row behind the other comb-tooth row, the conducting wire is stretched between the comb-teeth of both comb-like bodies, and the conducting wire in this state is transparent. A method for producing a transparent sheet material fixed to a transparent pressure-sensitive adhesive layer of a sheet base material is defined as a first gist,
A transparent sheet material in which two transparent sheet base materials each having a conducting wire fixed to a transparent adhesive layer are produced, and the conducting wires are superposed so that the conducting wires are orthogonal to each other to form a lattice, and are laminated and integrated. In the second summary of the manufacturing method of, the conductive sheet is fixed to the transparent pressure-sensitive adhesive layer to prepare the above-mentioned transparent sheet base material,
This is separated from the arrangement device and rotated by 90 degrees, while a second conducting wire is stretched between the comb teeth of both comb-like bodies of the arrangement device by using the arrangement device, and the second conducting wire in this state is The conducting wire is superposed on the conducting wire of the transparent pressure-sensitive adhesive layer of the transparent sheet base material which is rotated by 90 degrees to form a grid pattern of both conducting wires,
A third gist of the present invention is a method for producing a transparent sheet material in which a transparent pressure-sensitive adhesive layer of a transparent sheet base material different from the above transparent sheet base material is further stacked and integrated, and a plurality of comb teeth are linearly arranged at a constant pitch. A pair of comb-shaped bodies arranged in a zigzag shape is provided with two pairs of arranging devices in which comb teeth can be meshed with each other, and a second virtual line connecting the pair of comb-shaped bodies of the first set and a second line. The two array devices are positioned so that a virtual line connecting a pair of comb-shaped bodies intersects each other, and in each of the above-mentioned array devices, a conducting wire is arranged so as to cross a plurality of comb teeth of both the comb-shaped bodies. , And in that state, after engaging the comb teeth of both the comb-like bodies and further moving one of the comb-like bodies to position the comb-tooth row behind the other comb-tooth row, The conductive wire is stretched between the comb teeth of both comb-like bodies, and the conductive wire in the stretched state forms a grid pattern to make the transparent sheet substrate transparent. The method for producing a wear agent layer in a fixed transparency is sheet material and the fourth gist.

That is, the inventors of the present invention have made earnest studies in order to develop a method capable of producing a sheet material in which conducting wires are arranged at a constant pitch with high productivity. As a result, a plurality of comb teeth are linearly arranged at a constant pitch. A pair of comb-shaped bodies arranged in a zigzag shape is prepared such that the comb teeth of the comb-shaped bodies can be meshed with each other, and a conducting wire is arranged so as to cross the plurality of comb-shaped teeth of both the comb-shaped bodies. In that state, by engaging the comb teeth of the both comb-like bodies and further moving one of the comb-like bodies to position the comb-tooth row behind the other comb-tooth row, the conduction line By stretching between the comb teeth of the comb-like body and fixing the conducting wire in this state to the transparent adhesive layer of the transparent sheet base material, the conducting wire can be quickly arranged at a constant pitch. We found that it is highly efficient, has a small number of manufacturing steps, and can shorten the processing time, It has reached the first method of manufacturing.

In the first manufacturing method of the present invention, first, as an arranging device, a pair of comb-shaped bodies formed by arranging a plurality of comb teeth in a straight line at a constant pitch are arranged so that the comb teeth can mesh with each other. We are preparing the set up. Next, a conducting wire is arranged so as to cross a plurality of comb teeth of both comb-like bodies of the arrangement device, and in that state, the comb teeth of the both comb-like bodies are engaged with each other, and then one of the comb-like bodies is further removed. The comb tooth row is moved and positioned behind the other comb tooth row, whereby the conducting wire is stretched between the comb teeth of both comb-like bodies. Then, the conducting wire in this state is fixed to the transparent adhesive layer of the transparent sheet substrate. Therefore, one comb-like body is moved toward the other comb-like body from a state in which a pair of comb-like bodies formed by arranging a plurality of comb teeth in a straight line at a constant pitch are paired, and both comb-like bodies are moved. After passing the other comb-shaped body while meshing the comb teeth of the body, and then moving it to a predetermined position behind the other comb-shaped body, the conductive line is formed along with the comb-teeth row of the one comb-shaped body and the other comb-shaped body. When moving toward the comb tooth row of the other comb-shaped body and passing through the comb tooth row of the other comb-shaped body, the conductive line is caught at each comb tooth of the other comb-shaped body at a constant pitch, and one comb-shaped body Each comb tooth is pulled out at a constant pitch from the gap between the comb teeth of the other comb-shaped body, and is stretched while being arranged at a constant pitch between the comb teeth of both comb-shaped bodies. Then, by fixing the conducting wire in this state to the transparent adhesive layer of the transparent sheet base material, it is possible to manufacture a sheet material in which the conducting wires are arranged at a constant pitch. Such a sheet material is used by cutting the conducting wire in the vicinity of the comb teeth of both comb-like bodies and separating it from the comb teeth of both comb-like bodies.

As described above, in the first manufacturing method,
By moving one comb-shaped body to a predetermined position behind the other comb-shaped body from a state in which a pair of comb-shaped bodies formed by arranging a plurality of comb teeth in a straight line at a constant pitch are paired, The conducting wires can be quickly arranged at a constant pitch, and the manufacturing efficiency is excellent and the productivity is good. In addition, according to the first manufacturing method, the sheet material is obtained by fixing the conducting wires stretched in a state of being arranged at a constant pitch between the comb teeth of both comb-like bodies to the transparent adhesive layer of the transparent sheet base material. When the transparent electromagnetic wave shield material and the like are manufactured using this sheet material, the number of manufacturing steps is small, the processing time can be shortened, and the productivity is further improved. The term "conducting lines arranged at a constant pitch" means not only the case where the conducting lines are arranged in parallel but also the case where they are arranged in a slightly inclined state. For example, when the comb teeth of both comb-like bodies are meshed with each other, the gap between the comb teeth is appropriately set, and the diameter of the conducting wire and the pitch between the comb teeth are appropriately set. By combining these, it is possible to set the arrangement state of the conductive lines to a parallel state or a state in which the conducting lines are slightly inclined. Moreover, in each manufacturing method of the present invention, the “adhesive layer” is meant to include an adhesive layer.

Further, the inventors of the present invention can also quickly arrange the conducting wires at a constant pitch in the second manufacturing method of the present invention, have excellent manufacturing efficiency, have a small number of manufacturing steps, and reduce processing time. We have found that it can be shortened.

In the second production method of the present invention, first, two transparent sheet base materials (obtained by the first production method) having conductive lines fixed to a transparent pressure-sensitive adhesive layer are produced, and then,
The conducting lines are orthogonal to each other and are arranged in a grid pattern so as to be laminated and integrated. The sheet material thus obtained is used as a transparent electromagnetic wave shield material or the like.

As described above, in the second manufacturing method,
Since the transparent sheet base material obtained by the above-mentioned first manufacturing method is used, the conducting wires can be quickly arranged at a constant pitch, and the manufacturing efficiency is excellent and the productivity is good. Moreover, only two transparent sheet base materials need to be overlapped and laminated to be integrated. When manufacturing a transparent electromagnetic wave shielding material or the like, the number of manufacturing steps is small and the processing time can be shortened. Productivity is improved.

Also, the inventors of the present invention can also arrange the conducting wires at a constant pitch quickly even in the third manufacturing method of the present invention, which is excellent in manufacturing efficiency, has a small number of manufacturing steps, and requires a long processing time. We have found that it can be shortened.

In the third production method of the present invention, first, a transparent sheet base material (obtained by the above-mentioned first production method) in which a conducting wire is fixed to a transparent adhesive layer is produced, and then this is prepared. It is arranged to be rotated by 90 degrees separately from the array device (used in the first manufacturing method). On the other hand, the second conducting wire is stretched between the comb teeth of both comb-like bodies of the arranging device by using the arranging device, and the second conducting wire in this state is connected to the above-mentioned 9
A transparent pressure-sensitive adhesive layer of a transparent sheet base material, which is different from the above-mentioned transparent sheet base material, is formed by superposing on the conduction line of the transparent pressure-sensitive adhesive layer of the transparent sheet base material rotated by 0 ° Are further stacked and integrated. Therefore, in the third manufacturing method, the transparent sheet base material in which the conducting wires are arranged in one direction at a constant pitch is rotated by 90 degrees, and is further arranged by the arrangement device in the one direction at a constant pitch. Since the second conducting wire stretched over is overlapped with each other, it is possible to form a lattice shape with both conducting wires. The sheet material thus obtained is used as a transparent electromagnetic wave shield material or the like.

As described above, in the third manufacturing method,
Since the transparent sheet base material obtained by the first manufacturing method is used, the conducting wires can be arranged quickly at a constant pitch, which is excellent in manufacturing efficiency and has good productivity. In addition, the transparent electromagnetic wave shielding material and the like can be manufactured by using the above-mentioned arraying device again and stacking and integrating the transparent sheet base material with the second conductive wire superposed on the transparent sheet base material. The number of manufacturing steps is small, the processing time can be shortened, and the productivity is further improved.

The inventors of the present invention can also quickly arrange the conducting wires at a constant pitch even in the fourth manufacturing method of the present invention, have excellent manufacturing efficiency, have a small number of manufacturing steps, and reduce processing time. We have found that it can be shortened.

In the fourth manufacturing method of the present invention, first, as a set of two arranging devices, a pair of comb-shaped bodies in which a plurality of comb teeth are linearly arranged at a constant pitch are meshed with each other. We are preparing for the opposite. Then, the two sets of arraying devices are positioned so that an imaginary line connecting between the pair of comb-like bodies of the first set and an imaginary line connecting between the pair of comb-like bodies of the second set cross each other. Next, in both of the arrangement devices, conductive lines are arranged so as to cross the plurality of comb teeth of the both comb-like bodies, and in that state, the comb teeth of the both comb-like bodies are meshed with each other, The comb-like body is moved so that the comb-tooth row is positioned behind the other comb-tooth row, whereby each conducting wire is stretched between the comb-teeth of both comb-like bodies, and the conducting wire in the double-stranded state is stretched. To form a grid pattern and fix it to the transparent adhesive layer of the transparent sheet substrate. Therefore, in the fourth manufacturing method, the first
In the same manner as in the manufacturing method described above, the conducting wires are arranged in one direction at a constant pitch in the first set of aligning devices, and the conducting wires are arranged in a constant pitch in the direction intersecting the one direction in the second set of aligning devices. Array
After forming a grid with both conducting wires, by fixing both conducting wires in this state to the transparent adhesive layer of the transparent sheet substrate,
It is possible to manufacture a sheet material in which conductive lines are arranged in a grid. In the fourth manufacturing method of the present invention, the conductive wire used in the first manufacturing method may be used as the “second conductive wire”.

As described above, even in the fourth manufacturing method,
Since the conducting wires are arranged at a constant pitch in the same manner as the first manufacturing method, the conducting wires can be arranged at a constant pitch quickly, and the manufacturing efficiency is excellent and the productivity is good.
Moreover, according to the fourth manufacturing method, it is possible to obtain a sheet material obtained by fixing the conducting wires stretched in a lattice array to the transparent adhesive layer of the transparent sheet substrate. When a transparent electromagnetic wave shielding material or the like is manufactured using the material, the number of manufacturing steps is small, the processing time can be shortened, and the productivity is further improved.

In the present invention, when a part of the conductive line is exposed from the surface of the transparent pressure-sensitive adhesive layer of the transparent sheet base material, two transparent sheet base materials are superposed by the second manufacturing method. It is possible to stack the conductive wires in a state of abutting each other when they are matched with each other and when the grid is formed by both conductive wires by the third manufacturing method. As such a method of exposing a part of the conductive wire from the surface of the transparent adhesive layer of the transparent sheet substrate, the thickness of the transparent adhesive layer, and laminating conditions when fixing the conductive wire to the transparent adhesive layer. (temperature,
There is a method of appropriately changing the pressure). In addition, in each manufacturing method of the present invention, the conducting wire may be embedded in the transparent adhesive layer of the transparent sheet substrate. In particular, in the case of the above-mentioned fourth manufacturing method, it is easier to carry out the post-process when the conductive wire is embedded in the transparent adhesive layer of the transparent sheet substrate.

In the present invention, when the comb teeth forming the both comb-like bodies are provided with a rotation mechanism or the surfaces of the comb-teeth are provided with a sliding function, a conducting wire is provided between the both comb-like bodies. It can be moved smoothly. As a method for providing the above-mentioned comb tooth with a rotating mechanism, a roller is provided at a portion of the comb tooth through which the conducting wire passes, or a rotating mechanism such as a bearing is provided at a root portion of the comb tooth to rotate the entire comb tooth portion. Etc. are possible. Further, as a method of providing a sliding function on the surface of the comb teeth, a sliding process such as Teflon (R) coating is applied to a portion of the comb teeth through which the conducting wire passes, or a material of the comb teeth is made of resin with less friction. It is possible to use it as a material. Further, both of the comb-shaped bodies or the comb teeth may be provided with a rotating means for rotating the comb teeth themselves along the axis thereof.

In the present invention, the transparent sheet substrate
When a pressure-sensitive adhesive layer is formed on the surface opposite to the side where the conducting wire is fixed, and a member having releasability is attached to this pressure-sensitive adhesive layer, the above-mentioned pressure-sensitive adhesive is removed by peeling off the member. With the agent layer, the transparent sheet substrate can be easily attached to a front plate for a display member such as a cathode ray tube or a plasma display panel.
