Description
フッ素系潤滑油組成物の添加剤成分として用いられる含フッ素化合物は、窒素原子を有するため、分子構造中に非共役電子対を持ち、金属表面に適正な配位能を発揮する。また、分子骨格中にアミド結合を持つことにより、金属表面との配位能をより安定化させるといった働きも併せ持っている。これらの高い配位能により、金属表面への吸着が強くなり、金表面、銀表面、金メッキ表面、銀メッキ表面等の貴金属表面、銅表面、少量の添加元素、例えばAg、Cd、Cr、Be、Be-Co、Te、Zn、Sn、Al、Ni、Si、Pb等との銅合金の表面に対しすぐれた耐摩擦摩耗性を発揮することができる。 Since the fluorine-containing compound used as an additive component of the fluorine-based lubricating oil composition has a nitrogen atom, it has a non-conjugated electron pair in the molecular structure and exhibits an appropriate coordination ability on the metal surface. In addition, by having an amide bond in the molecular skeleton, it also has the function of further stabilizing the coordination ability with the metal surface. These high coordinating capabilities enhance the adsorption to the metal surface, such as gold surface, silver surface, gold-plated surface, noble metal surface such as silver-plated surface, copper surface, small amounts of additive elements such as Ag, Cd, Cr, Be Excellent friction and wear resistance can be exerted on the surface of copper alloys such as Be-Co , Te, Zn, Sn, Al, Ni, Si, and Pb.
含フッ素化合物の製造に用いられるパーフルオロポリエーテル酸フロライドは、公知の方法で容易に得ることができ、一般的にはヘキサフルオロプロピレンオキサイドをフッ化セシウム触媒およびテトラグライム溶媒の存在下でオリゴマー化反応させると、一般式〔IV〕に示されるようなパーフルオロポリエーテルが得られる。
Perfluoropolyether acid fluoride used in the production of fluorine-containing compounds can be easily obtained by a known method. Generally, hexafluoropropylene oxide is oligomerized in the presence of a cesium fluoride catalyst and a tetraglyme solvent. When reacted, a perfluoropolyether represented by the general formula [IV] is obtained.
また、分岐構造を持たないパーフルオロポリエーテル酸フロライドも、公知の方法で得ることができる。その一例として、一般式〔V〕に示されるようなテトラフルオロエチレンオキサイドの光酸化重合によりテトラフルオロエチレンオキサイド単位とジフルオロメトキシ単位が不規則に結合したものが挙げられる。
CF3O(CF2O)p(CF2CF2O)qCF2COF 〔V〕
Further, perfluoropolyether acid fluoride having no branched structure can also be obtained by a known method. As an example, there may be mentioned those in which tetrafluoroethylene oxide units and difluoromethoxy units are irregularly bonded by photo-oxidative polymerization of tetrafluoroethylene oxide as represented by the general formula [V] .
CF 3 O (CF 2 O) p (CF 2 CF 2 O) q CF 2 COF (V)
以上の例に示される如く、フルオロカーボン基Rfは炭素数1〜2のパーフルオロアルキレン基または分岐パーフルオロアルキレン基であり、具体的には-CF2-、-CF2CF2-、-CF(CF3)-基が示される。 As shown in the above example, the fluorocarbon group Rf is a perfluoroalkylene group or a branched perfluoroalkylene group having 1 to 2 carbon atoms, -CF 2 specifically -, - CF 2 CF 2 - , - CF ( CF 3 ) -group is shown.

Each of the prepared greases is 0.25 mm thick on a 2 mm thick silver-plated plate [Ag] , copper alloy (C1100) plate [Cu] , gold-plated plate [Au] and stainless steel S45C plate [Fe]. Apply and apply grease to each tribogear surface property measuring machine (manufactured by Shinto Kagaku) and set each metal plate and ball of the same material as the metal used, and perform a friction and wear test under the following measurement conditions. The wear depth (unit: μm) of each metal plate was measured.
