Description
本発明は、熱可塑性樹脂、紫外線硬化剤、ゴム、エラストマー又は粘着剤などに添加し、樹脂あるいは基材等に導電性を付与するために用いる導電性付与剤及び該導電性付与剤が添加されてなる導電性材料に関する。 In the present invention, a conductivity imparting agent used for imparting conductivity to a resin or a substrate is added to a thermoplastic resin, an ultraviolet curing agent, rubber, an elastomer or an adhesive, and the conductivity imparting agent is added. It relates to a conductive material.
熱可塑性樹脂、紫外線硬化剤、ゴム、エラストマー又は粘着剤等に導電性付与剤が添加されてなる導電性材料は、防塵シート、帯電防止フィルム、除電マット、帯電防止床材などの導電性シート、電子写真式プリンターや複写機の導電性ロール（帯電ロール、現像ロール、転写ロールなど）、磁気記録媒体用基材、半導体用素材、液晶ディスプレイなどの保護フィルムなどに用いられている。 A conductive material obtained by adding a conductivity-imparting agent to a thermoplastic resin, an ultraviolet curing agent, rubber, an elastomer, or an adhesive is a conductive sheet such as a dustproof sheet, an antistatic film, a static elimination mat, an antistatic flooring, It is used for conductive rolls (charging rolls, developing rolls, transfer rolls, etc.) of electrophotographic printers and copying machines, base materials for magnetic recording media, semiconductor materials, protective films for liquid crystal displays, and the like.
従来、導電性付与剤に使用されるイオン導電剤として、過塩素酸リチウムが知られている（例えば特許文献１参照）。過塩素酸リチウムは、他のイオン導電剤と比較して帯電防止性、すなわち導電性に優れ、さらに安価であるためコスト的に非常に有利なイオン導電剤であるが、該化合物は消防法に定める危険物第１類に属する酸化性固体であり、可燃物と混合すると発熱、発火の危険性があるため、取り扱い上、特段の注意を要し、樹脂等への添加量が制限される。すなわち、導電性に優れた導電性材料を得るべく、高濃度の過塩素酸リチウムを添加した導電性付与剤の製造は、安全面から困難を伴うものである。 Conventionally, lithium perchlorate is known as an ionic conductive agent used for a conductivity imparting agent (see, for example, Patent Document 1). Lithium perchlorate is an ionic conductive agent that is very advantageous in terms of cost because it is superior in antistatic property, that is, conductivity, and is cheaper than other ionic conductive agents. Since it is an oxidizable solid belonging to the first class of hazardous materials and there is a risk of heat generation and ignition when mixed with combustible materials, special care is required in handling, and the amount added to the resin is limited. That is, in order to obtain a conductive material having excellent conductivity, it is difficult to produce a conductivity imparting agent to which a high concentration of lithium perchlorate is added.
近年、イオン導電剤として、ビス（トリフルオロメタンスルホニル）イミド酸リチウムやトリス（トリスフルオロメタンスルホニル）メタン酸リチウム等の含フッ素有機アニオン塩類を用いた導電性付与剤が提案されている（例えば特許文献２参照）。該化合物は、比較的導電性が良好で、相溶性が良いなど導電性材料として優れた特性を有している。しかし近年では更に高い導電性を有する導電性材料の開発が望まれている。 In recent years, conductivity imparting agents using fluorine-containing organic anion salts such as lithium bis (trifluoromethanesulfonyl) imidoate and lithium tris (trisfluoromethanesulfonyl) methanoate have been proposed (for example, patent documents). 2). The compound has excellent properties as a conductive material, such as relatively good conductivity and good compatibility. However, in recent years, development of a conductive material having higher conductivity has been desired.
本発明の目的は、熱可塑性樹脂、紫外線硬化剤、ゴム、エラストマーまたは粘着剤などへ混練する際に、相溶性良く簡便に混練することができ、非常に高い導電性を付与させることができる導電性付与剤及び導電性材料を提供することである。また、該導電性材料を使用し、ブリード等発生せず、安定性に優れた導電性部材、導電性フィルムを提供することにある。 The object of the present invention is to conduct kneading into thermoplastic resins, ultraviolet curing agents, rubbers, elastomers or pressure-sensitive adhesives, and the like, which can be easily kneaded with good compatibility and can impart very high conductivity. It is providing a property imparting agent and a conductive material. Another object of the present invention is to provide a conductive member and a conductive film that are excellent in stability and that do not generate bleed or the like using the conductive material.
前記課題に鑑み、本発明者らは鋭意検討した結果、イオン導電剤として、ビス（フルオロスルホニル）イミド塩をポリエーテルポリオールに溶解させてなる導電性付与剤が、前記課題を解決し得ることを見いだし、本発明を完成するに至った。 In view of the above problems, the present inventors have intensively studied.
