装材料等に用いる帯電防止性を有する材料の製造方法に
関するものである。Detailed Description of the Invention [Industrial Application Field] The present invention relates to an antistatic material used for packaging materials, etc. used for bags, containers, or lids for packaging parts of electrical equipment products, or electronic equipment or parts. The present invention relates to a method for producing a material having properties.
電子機器製品が高度化、精密化するに伴ない、集積回路
や大規模集積回路が利用される様になったが、これらは
微量の静電気により静電気破壊を起しやすく、また感光
材料も高感度化しており、たとえばＸ線フィルムなども
静電気の発生によりスタチックマークと呼ばれる一種の
露光現象を起しやすい。As electronic products have become more sophisticated and precise, integrated circuits and large-scale integrated circuits have come into use, but these are easily damaged by static electricity due to minute amounts of static electricity, and photosensitive materials also have high sensitivity. For example, X-ray films are prone to a type of exposure phenomenon called static marks due to the generation of static electricity.
これら感静電気性の材料あるいは部品を包装する際に、
汎用のプラスチックフィルム、例えばポリエチレン、ポ

電しやすく、作業中あるいは輸送中に発生する静電気に
より、静電破壊をはじめとした種々の静電気障害を起し
やすく、包装材料としては難しい問題を抱えていた。When packaging these static-sensitive materials or parts,
When using general-purpose plastic films such as polyethylene, polypropylene, polyvinyl chloride, polyethylene terephthalate, polyamide, etc., these general-purpose plastic films are insulating materials, so they are extremely susceptible to being charged with electricity and may be easily charged during work or transportation. The generated static electricity tends to cause various electrostatic damage including electrostatic damage, which poses a difficult problem as a packaging material.

土性も不均一なものとなる。一方、イオン性の界面活性
剤、いわゆる帯電防止剤を樹脂中に混入させた場合には
、その効果が湿度の影響を受けやすく、均一性、持続性
などに於て好ましいものではない。Conventionally, in order to prevent this kind of trouble, general-purpose resins such as polyethylene were mixed with conductive fillers such as conductive carbon fine powder or metal fine powder and dispersed therein, or they were mixed with ionic surfactants. There is something mixed in. However, it is difficult to completely and uniformly disperse these fine carbon powders and fine metal powders in the resin.
If the dispersion is incomplete, the desired conductivity will not be obtained and the anti-static property will be non-uniform. On the other hand, when an ionic surfactant, a so-called antistatic agent, is mixed into the resin, its effect is easily affected by humidity, which is not preferable in terms of uniformity, sustainability, etc.
また、これら導電性フィラーを樹脂中に分散させる為、

促進する界面活性剤の低分子量性などが必要であるが、

あるいは樹脂の成膜時の熱履歴を受けて、界面活性剤の
分散、揮散などがあり、効果の均一性・持続性などに於
て好ましいものではない。In addition, in order to disperse these conductive fillers into the resin,
It inhibits heat sealability (thermal fusion) and impairs its function as a packaging material. On the other hand, when an ionic surfactant, a so-called antistatic agent, is mixed into the resin,
Its effect is easily affected by humidity, and it bleeds onto the surface of the resin to produce its effect.
Incompatibility between the resin and surfactant, low molecular weight of the surfactant that promotes the mobility of the surfactant, etc.
These are the former, which is due to the incompatibility of the surfactant, which comes off over time and during transportation, and the latter, which is due to the volatility of the surfactant.
Alternatively, the surfactant may be dispersed or volatilized due to the thermal history during resin film formation, which is not preferable in terms of uniformity and sustainability of the effect.
本発明はこのような現況を鑑みてなされたものである。 The present invention has been made in view of these current circumstances.
即ち、本発明は極めて透明で、かつ均一性、持続性を有
し、しかも袋等を製造可能な帯電防止性を有する材料を
得る製造方法を提供する事を目的としている。That is, an object of the present invention is to provide a manufacturing method for obtaining a material that is extremely transparent, has uniformity and durability, and has antistatic properties that can be used to manufacture bags and the like.

特徴としている。Specifically, as shown in FIG. 1, the laminated surface 3 of a hydrophobic plastic film or sheet serving as the base material 1 is subjected to low-temperature plasma treatment with oxygen or a mixed gas of oxygen and nitrogen,
It is characterized in that a water-soluble binder containing ferric chloride as a catalyst is coated thereon, and after drying, a polypyrrole layer 2 is partially laminated by leaving it in a pyrrole gas phase.

It was invented to compensate for these shortcomings. That is,
The hydrophilicity of the laminated surface of the base material hydrophobic plastic film or sheet is significantly improved by subjecting it to low-temperature plasma treatment with oxygen or a mixed gas of oxygen and nitrogen, and as a result, the water-soluble binder and It is characterized by increasing the adhesive strength of
