効果を減少させる等の欠点があつた。Since a synthetic resin sheet is easy to manufacture and can be made transparent, it is often used for covers of various devices and curtains for isolation. However, static electricity may be generated on the surface of the synthetic resin sheet due to the flow of air accompanying the movement of a person or an object, which may accumulate on the synthetic resin sheet and cause an unexpected accident. For example, when used as a curtain in a place where SI is handled, or as a cover for precision equipment equipped with SI,
A small amount of static electricity may cause the SI function to be impaired. Therefore, when a synthetic resin sheet is used as a curtain for isolation in a place where SI or the like is handled, or as a cover for precision equipment equipped with SI or the like, it is necessary to perform antistatic processing on the synthetic resin sheet. In the conventional antistatic processing, an antistatic agent is applied to the front and back surfaces of a synthetic resin sheet in whole or in part, for example, in a grid pattern. However, since it is simply applied to the surface, the antistatic agent may fall off due to friction during use, etc., or the plasticizer contained in the synthetic resin sheet may migrate to the surface, and There were drawbacks such as reduced effectiveness.
本発明は摩擦等による帯電防止剤の脱落あるいは可塑剤

多かつた従来の合成樹脂シートを改良し、摩擦等に対し

提供しようとするものである。The present invention improves the conventional synthetic resin sheet that often loses its antistatic effect due to the removal of the antistatic agent due to friction or the like or the transfer of the plasticizer to the surface, and improves the resistance to friction and the like. It is an attempt to provide an antistatic cover or isolation curtain.

る。The present invention solves the above-mentioned problems, in which a thin layer of soft PVC is laminated on both sides of a conductive nonwoven fabric mainly composed of synthetic resin fibers by heat welding, and numerous small holes penetrating the laminated sheet are formed on the entire surface. An antistatic cover or a separating curtain made of a laminated sheet having a thickness of 0.1 to 0.25 mm.

ある。又透明性を要求される場合不織布の厚み即ち重量
は10〜15ｇ／m2であることが好ましい。The conductive non-woven fabric mainly composed of synthetic resin fibers according to the present invention may be any non-woven fabric having electroconductivity. For example, an acrylic non-woven fabric may be coated with a coating material containing a conductive substance such as carbon, a copper compound or a tin compound, or may be a mixed fabric of carbon fibers and other conductive fibers. Since the PVC thin layers laminated on the upper and lower sides of the non-woven fabric are heat-welded to each other through the gaps of the non-woven fabric, the material of the non-woven fabric is not necessarily compatible with PVC, but is transparent to the laminated sheet. When the property is required, the material of the nonwoven fabric must be compatible with PVC. When transparency is required, the thickness or weight of the nonwoven fabric is preferably 10 to 15 g / m 2 .

おいてもよい。The soft PVC thin layer preferably has a thickness of 50 to 200 microns and is preferably flame-retarded. Also, soft PVC with different surface and back surface of conductive non-woven fabric
Thin layers may be laminated. In addition, characters or patterns may be printed on the soft PVC thin layer. When a soft PVC thin layer is laminated on both sides of a conductive non-woven fabric and the three members are heat-welded at the same time, a uniform laminated sheet cannot be obtained due to shrinkage of the non-woven fabric and the like. A soft PVC thin layer is previously laminated on a release paper with a calendar, and a conductive non-woven fabric is laminated thereon and heat-welded. Next, a soft PVC thin layer may be further laminated with a calendar. The release paper used at this time may be removed after lamination, but may be left as it is until the end.

このようにして作られた積層シートは適度の厚み好まし

る効果の減少もないものである。In the antistatic cover or isolation curtain according to the present invention, when static electricity is generated on the surface, the static electricity is guided to the conductive non-woven fabric sheet through the small holes, and subsequently, in the case of a curtain, a curtain hanger or a lower end. In the case of the cover of the device, the fixing fitting does not discharge to the outside of the system by the grounding tool attached to the cover, and static electricity does not accumulate on the curtain or the cover. Therefore, it can be used as a curtain or a cover even for an object such as SI that is easily affected by static electricity. Furthermore, since the conductive substance is inside the laminated sheet and is not exposed on the surface, the conductive substance does not drop off due to friction or the like, and the effect due to the transfer of the plasticizer does not decrease.

ある。When static electricity is generated in the cover or the separating curtain according to the present invention, the static electricity is guided to the conductive substance inside the laminated sheet through the small holes penetrating the laminated sheet and discharged to the outside of the system. Alternatively, the effect that static electricity does not accumulate in the isolation curtain and the conductive material that induces static electricity is inside the laminate and is not exposed on the surface, so it may fall off due to friction, or the plasticizer may migrate to the surface. Therefore, there is no drawback that the antistatic effect is reduced.
