Description
【0011】
更に伸び率は大きいほど破壊されることなく変形する範囲が大きい特性を示しており、バインダであるポリアミドイミド樹脂の伸び率が大きいほど潤滑膜が破壊することなく変形することができ、潤滑膜の変形によって接触応力を分散し低減することができる。これにより摩擦係数を低減することができ、優れた摩擦特性を有することが可能となる。また伸び率が大きければ破壊することなくのびるので、優れた耐摩耗性を有することができる。この場合ポリアミドイミド樹脂の伸び率が10%未満であると、接触応力を分散して、摩擦係数を低減する効果が不十分となる。逆に伸び率が20%を超えると、潤滑膜の変形が大きくなり、潤滑膜の摺動部材との密着性が不十分となる。[0011]
Furthermore, the larger the elongation percentage, the larger the range of deformation without breakage, and the larger the elongation percentage of the polyamideimide resin as the binder, the more the lubricant film can be deformed without breakage, and Contact stress can be dispersed and reduced by deformation. This makes it possible to reduce the coefficient of friction and to have excellent friction characteristics. In addition, if the elongation rate is high, it can extend without breaking, so it can have excellent wear resistance. In this case, when the elongation of the polyamideimide resin is less than 10%, the contact stress is dispersed, and the effect of reducing the friction coefficient becomes insufficient. On the contrary, when the elongation rate exceeds 20%, the deformation of the lubricating film becomes large, and the adhesion between the lubricating film and the sliding member becomes insufficient.

固体潤滑剤は、公知のものから適切なものを選択して用いることができるが、
固体潤滑剤をバインダであるポリアミドイミド樹脂に分散させて潤滑膜を摺動部材の表面に形成することにより、摩擦係数を低減させて、なじみ性を確保することができる。なお2硫化モリブデン(MoS2)及び2硫化タングステン(WS2)等の硫化物、ポリテトラフルオロエチレン(PTFE)、テトラフルオロエチレン-パーフルオロアルキルビニルエーテル共重合体、テトラフルオロエチレン-ヘキサフルオロフロピレン共重合体、テトラフルオロエチレン-エチレン共重合体、ポリビニリデンフルオライド及びポリクロロトリフルオロエチレン等のフッ素化合物、黒鉛(グラファイト)、フッ化黒鉛等から選択することが好ましく、硫化物、フッ素化合物、黒鉛のうち1種、2種又は3種を選択して用いることが摩擦特性、耐焼き付き性の向上の観点から好ましい。詳細なデータを特に記載しないが、硫化物、フッ素化合物、黒鉛とも同様な効果を示すことが確認されている。[0017]
The solid lubricant can be selected from known ones and used appropriately.
By forming a lubricating film on the surface of a sliding member by dispersing a solid lubricant in a polyamide-imide resin as a binder, the coefficient of friction can be reduced, and conformability can be ensured. In addition, sulfides such as molybdenum disulfide (MoS 2 ) and tungsten disulfide (WS 2 ), polytetrafluoroethylene (PTFE), tetrafluoroethylene-perfluoroalkyl vinyl ether copolymer, tetrafluoroethylene-hexafluoroflopylene copolyester It is preferable to select from polymers, tetrafluoroethylene-ethylene copolymers, fluorine compounds such as polyvinylidene fluoride and polychlorotrifluoroethylene , graphite (graphite), fluorinated graphite and the like, and sulfides, fluorine compounds, graphite It is preferable to select and use one, two or three of them from the viewpoint of improving the friction characteristics and the seizure resistance. Although detailed data are not particularly described, it is confirmed that sulfide, fluorine compound and graphite show similar effects.
