【従来の技術】
従来、PPS樹脂による摺動部材としては黒鉛、ポリテトラフルオエチレン樹脂(PTFE樹脂)、芳香族ポリアミド繊維、無機化合物、固体潤滑剤、金属酸化物及び潤滑油等の任意の組み合わせによる組成物が知られている。例えば特開昭59-215353におけるPPS樹脂にチタン酸カリウム繊維を添加した組成物、特開昭58-152051におけるPPS樹脂にチタン酸カリウム繊維と鉱物油を添加した組成物、特開平4-63866におけるPPS樹脂にアラミド繊維及び/またはチタン酸カリウム繊維及びPTFE樹脂、硫化モリブデン、超高分子量ポリエチレンからなる樹脂組成物、特公昭60-11061におけるPPS樹脂にPTFE樹脂、金属酸化物、芳香族ポリアミド繊維、金属粉末を配合してなる樹脂組成物、特公平4-65866 におけるPPS樹脂にフッ素樹脂と芳香族ポリアミド繊維からなる樹脂組成物等が知られている。

2. Description of the Related Art
Conventionally, known sliding members made of PPS resin include compositions containing any combination of graphite, polytetrafluoroethylene resin (PTFE resin), aromatic polyamide fiber, inorganic compounds, solid lubricants, metal oxides, and lubricating oils. For example, JP-A-59-215353 discloses a composition containing potassium titanate fiber added to PPS resin, JP-A-58-152051 discloses a composition containing potassium titanate fiber and mineral oil added to PPS resin, JP-A-4-63866 discloses a resin composition containing aramid fiber and/or potassium titanate fiber, PTFE resin, molybdenum sulfide, and ultra-high molecular weight polyethylene in PPS resin, JP-B-60-11061 discloses a resin composition containing PTFE resin, metal oxide, aromatic polyamide fiber, and metal powder in PPS resin, and JP-B-4-65866 discloses a resin composition containing fluororesin and aromatic polyamide fiber in PPS resin.

【0003】
また、導電性樹脂材料としては炭素繊維、カーボンブラック及び導電性を付与した無機化合物または無機物繊維の添加による方法が知られている。例えば特開平2-67358における熱可塑性樹脂に導電性チタン酸カリウム繊維と導電性カーボンブラックを添加した樹脂組成物、特公平4-68348における熱可塑性樹脂に導電性チタン酸カリウム繊維と導電性カーボンブラック及びガラス繊維及び/または炭素繊維が配合された樹脂組成物、特公平5-61306におけるPPS樹脂にニッケルで表面を被覆した雲母とニッケルで表面を被覆したワラストナイトまたはチタン酸カリウム繊維、炭素繊維、PTFE樹脂、二化モリブデンを添加してなる樹脂組成物等が知られている。
[0003]
Also, methods for adding carbon fibers, carbon black, and inorganic compounds or inorganic fibers that have been given electrical conductivity to the resin material are known. For example, JP-A-2-67358 discloses a resin composition in which electrically conductive potassium titanate fibers and electrically conductive carbon black are added to a thermoplastic resin, JP-B-4-68348 discloses a resin composition in which electrically conductive potassium titanate fibers, electrically conductive carbon black, and glass fibers and/or carbon fibers are blended with a thermoplastic resin, and JP-B-5-61306 discloses a resin composition in which nickel-coated mica, nickel-coated wollastonite or potassium titanate fibers, carbon fibers, PTFE resin, and molybdenum disulfide are added to a PPS resin.

【0019】
以上本発明における樹脂組成物に於いては、前記した全ての添加材を添加することにより所望する効果が実現でる。つまり、導電性チタン酸カリウム繊維が添加されると必要な導電性と補強効果は得られ、PTFE樹脂を添加ことにより耐摩擦摩耗特が向上する。また、金属酸化物を添加することによりアルミなど軟質相手材に対する耐摩耗性と安定した導電性が得られ、芳香族ポリアミド繊維を添加することによりアルミなど軟質相手材に対する安定した摺動特性の向上が望める。
[0019]
As described above, the resin composition of the present invention can achieve the desired effects by adding all of the additives described above. That is, the addition of conductive potassium titanate fiber provides the necessary conductivity and reinforcing effect, and the addition of PTFE resin improves friction and wear resistance. Furthermore, the addition of metal oxide provides wear resistance and stable conductivity against soft mating materials such as aluminum, and the addition of aromatic polyamide fiber is expected to improve stable sliding properties against soft mating materials such as aluminum.

[Example]
The following examples will be given to describe the specific embodiments and effects of the invention.
Examples 1 to 9, Comparative Examples 1 to 9
PPS resin (Toray Industries, Inc.: PPS Bulk Powder M-2900), PTFE resin (Sanko Shoji: SG-1000), zinc oxide (Maruo Calcium: Zinc Oxide ZA-100), aromatic polyamide fiber (DuPont Toray: KC-20), and conductive potassium titanate fiber (Otsuka Chemical: "Dentol" BK-300) were compounded in the formulations shown in Table 1 below. All raw materials were first mixed in a Henschel mixer, then fed into a twin-screw extruder set at a cylinder temperature of 300°C, where they were melt-kneaded and extruded at 70-100 rpm for granulation. The resulting composition was then molded in an in-line screw injection molding machine at a mold temperature of 140°C and a molding temperature of 310°C to produce bearing test pieces and property measurement test pieces of the shape shown in Figure 1.
